Content tips: China's tape industry enterprises are widely distributed, a large number, but relatively concentrated. Almost all provinces and autonomous regions in China have belt production enterprises, and there are hundreds of large and small enterprises; however, belt enterprises are mainly concentrated in Zhejiang, Shandong, Hebei, Henan, Shanghai, Jiangsu, Liaoning, Guangdong and other provinces and cities.

Basic status and position of tape industry in China

1.1 production capacity and output

China is a big producer and consumer of adhesive tape in the world. There are more than 100 adhesive tape manufacturers in China. It is roughly estimated that the annual rubber consumption (including resin) of rubber belt products in China in 2004 is about 100000 tons, accounting for about 1 / 3 of the world rubber belt consumption and about 2.5% of the national rubber products consumption. According to the rough statistics of the industry, the annual production capacity of conveyor belt in China is about 250 million m2, and the annual production capacity of V belt is more than 1 billion am, ranking the top in the world. According to the statistical data of relevant departments, the output of conveyor belts in China from 2001 to 2004 were 7246, 7327.52, 8876.21 and 100 million m2 respectively, and the output of V belts were 63700, 65410.45, 76341.2 and 880 million am respectively. It is estimated that the gross output value of rubber belt products in 2004 is about 6 billion yuan, accounting for about 4% of the total value of rubber products in China.

According to the statistics of the customs, the export delivery value of the national adhesive tape products from 2001 to 2004 were US $6300, US $6256, US $8635 and US $127.2 million respectively, and the import value was US $6011, US $6200, US $10415 and US $119.16 million respectively. It can be seen that the export delivery value of China's tape products in 2004 has a greater growth than that in 2003, but it is still basically the same as that of import. Generally speaking, China's tape products are self-sufficient, and some of them are exported, resulting in excess production capacity. On the contrary, due to the variety, specification, quality level and other factors, some of them are imported every year.

1.2 characteristics of regional development

In China, there are many enterprises in the belt industry, but they are relatively concentrated. Almost all provinces and autonomous regions in China have belt production enterprises, and there are hundreds of large and small enterprises; however, belt enterprises are mainly concentrated in Zhejiang, Shandong, Hebei, Henan, Shanghai, Jiangsu, Liaoning, Guangdong and other provinces and cities. In addition, the production of the top 10 in China's belt industry accounts for more than 60% of the total output of the country's belt. For example, according to the statistics of Zhejiang Rubber Industry Association, in 2004, the province's V-belt output reached 450 million am, accounting for 51.1% of the total national output; the conveyor belt output reached 14.06 million m2, accounting for 14% of the total national output; the export delivery value of belt reached 288 million yuan, accounting for 1 / 4 of the national export delivery value of belt. The belt industry in Zhejiang Province is concentrated in Ningbo, Shaoxing, Tongxiang, Sanmen, Tiantai and other areas. For another example, according to the statistics of Shandong Rubber Industry Association, in 2004, the conveyor belt output of Enterprises above Designated Size in Shandong Province reached 29.4 million m2, accounting for about 30% of the total conveyor belt output in China. According to the investigation of the belt Management Branch, the conveyor belts in Hebei Province are mainly concentrated in Lixian and Boye, with a production capacity of about 50 million m2 and an annual output of 30 million m2.

1.3 joint venture

Since the reform and opening up, China's tape industry has been expanding foreign cooperation, actively introducing foreign capital, and has established a number of joint ventures or wholly-owned enterprises, such as Shandong Yinhe Depu tape Co., Ltd., Shanxi Fenghuang tape Co., Ltd., Dongsen automotive rubber products Co., Ltd. These enterprises have a certain influence in the industry because of their advantages in capital and technology, better technical equipment and higher product quality.

1.4 product quality

In the past 20 years, the development of belt products in China is very fast, whether it is conveyor belt, or the variety of transmission belt is relatively complete, and in line with international standards. In terms of product quality, we should pay more attention to the timely adoption of international standards and foreign advanced standards. At present, there are more than 30 national or industrial standards for products. These national or industrial standards are basically formulated with reference to international standards or foreign advanced standards. At present, the conveyor belt with synthetic fiber and steel wire rope core as the skeleton accounts for about 80% of the total conveyor belt in China, and the V-belt with wire rope structure is close to 80% of the total V-belt, which is close to the international advanced level. Since 2003, the state has implemented the production license system for flame retardant conveyor belt and automobile V-belt, which is a great promotion for the improvement of the quality level of belt products in China. Flame retardant conveyor belt includes four types: fabric core flame retardant conveyor belt (PVC type and PVG type), steel wire core flame retardant conveyor belt and general purpose flame retardant conveyor belt, and its output accounts for about 1 / 3 of the total output of conveyor belt. Because the flame retardant conveyor belt is required to be flame retardant and static conductive, and it is also used in the flammable and explosive places controlled by the state, the technical content of the product is relatively high, and the quality level of the product can represent the quality level of conveyor belt products in China to some extent. There are two types of automobile V-belt, i.e. wrapping V-belt and trimming V-belt. Automobile V-belt is also a high-tech product in V-belt products because of its relatively strict service conditions. Its quality status can also represent the quality status of V-belt products in China to some extent.

From the sampling inspection, the strength and width of flame retardant conveyor belt in China are still low. In addition, there is still a certain gap between the actual service life and appearance quality of conveyor belt in China and foreign advanced level, which are the direction of our future efforts. However, the quality of V-belt products needs to be further stabilized and improved, the fatigue life of V-belt still lags behind the advanced level of foreign countries, and the wrapped V-belt still accounts for a certain proportion, so the pace of upgrading should be accelerated.

1.5 production technology level

At present, the overall development level of China's belt industry is basically synchronized with the international advanced level. Some large and medium-sized tape enterprises have successively introduced a number of more advanced tape production equipment and technology from Europe, America, Japan and other developed countries and regions. At the same time, on the basis of digestion and absorption, they have also developed a number of tape production technology and equipment close to the international advanced level and with Chinese characteristics, which has gradually brought China's tape production technology level to a new level and is in line with the international advanced level Flat approach. In addition, the emergence of a number of joint ventures and wholly-owned enterprises also promoted the improvement of China's tape production technology.

However, due to capital, system, management and other reasons, the development of production technology level of tape enterprises in China is not balanced, and the equipment and technology level of some enterprises are still relatively backward. Compared with the advanced level of foreign countries, the gap between China's tape production technology level and foreign advanced level is relatively large, which is also reflected in the detection means. At present, the static test means of some large and medium-sized belt enterprises in China are basically complete, but the dynamic test means are generally lacking, especially the various dynamic test equipment for conveyor belt, which is basically blank. The dynamic test machine for transmission belt imported from abroad has been gradually aging, and the quality of domestic products needs to be further improved. In order to ensure the quality level of our belt products, the backward ones are not suitable The detection situation needs to be changed.

1.6 economic benefits

In recent years, thanks to the development of China's coal, steel, electric power, mining, automobile, agricultural machinery and other industries, the output of conveyor belt and V-belt in China has increased significantly year after year. Although the output has increased, the economic benefit of the industry has decreased. According to the statistics of 41 tape member units of the management belt branch, compared with 2003, there are 30 enterprises whose economic benefits have declined, accounting for 73% of the total number of members, and 20 enterprises with losses, accounting for 48.7%. Some enterprises with a good foundation have also seen their profits decline. There are probably three reasons: first, the price of raw materials has increased significantly, and the cost of products has increased. In 2004, the price of raw materials needed by the belt industry rose, with an increase of about 30%. Second, the price war disrupted the market. Conveyor belt users set the standard by price, and peer pressure is serious. In the case of rising prices of raw materials, the price of adhesive tape will not rise, but fall. Third, the oversupply leads to the fact that users ignore the rising prices of raw materials and product costs, and still wantonly depress the prices. In order to occupy the market, some enterprises have to bear the pain of reducing prices, resulting in disorderly competition, and eventually the economic benefits of the industry have been lost.

However, some enterprises with relatively strong strength have achieved better economic benefits by adhering to the principle of winning by quality, profit being more important than market share, and not blindly reducing prices in competition.

1.7 main raw materials

Elastomeric materials for tape products in China mainly include natural rubber, styrene butadiene rubber, cis-1,4-polybutadiene rubber, nitrile butadiene rubber, chloroprene rubber, ethylene propylene rubber, PVC resin, etc. According to the estimation of the total output of the belt, about 100000 tons of various elastomers and 150000 tons of various additives including carbon black were consumed in 2004. Polyester is the main backbone material of belt products in China, followed by nylon, steel wire, glass fiber and cotton fiber. According to the estimation of the total output of belt, the conveyor belt consumed about 35000 tons of core fabric and 10000 tons of steel wire in 2004; the V belt consumed about 10000 tons of polyester cord and curtain cloth, and about 30000 tons of polyester cotton canvas.

2. Forecast of production and demand development

2.1 market analysis

The development of belt industry mainly depends on the development of coal, steel, cement, electric power, port, mine, automobile, petroleum, textile, light industry, machinery and other industries. Since the tenth five year plan, the sustained and rapid development of China's national economy has driven the development of the above industries and brought good opportunities for the development of the belt industry. In 2004, China's coal production exceeded 1.9 billion tons, with an average annual growth of more than 200 million tons; steel production reached 272 million tons; power generation reached 220 million kwh; cement production was about 950 million tons, ranking first in the world. Automobile production reached 5.0705 million, ranking fourth in the world, with a year-on-year growth of 14.1%. 98300 large and medium-sized tractors, with a year-on-year increase of 83.9%; 1794000 small tractors, with a year-on-year increase of 0.9%.

At the same time, the measures taken by the state to expand domestic demand are expected to continue to be implemented for a period of time, which will undoubtedly drive the development of automobile, building materials, light industry and other industries. In addition, the western development strategy and the national policy of attaching importance to "agriculture, rural areas and farmers" will continue for a long time, which will open up a broad potential market for China's belt industry. For example, as a pillar industry of China's national economy, the automobile industry will be supported and developed by the state. According to the prediction of relevant parties, the total demand for automobiles in 2005 will reach 5.8 million, with a year-on-year increase of 12%, including 2.75 million cars, an increase of 17%, the growth rate of production will remain at 15% ~ 20%, and the production and sales volume will be nearly 6 million. At the same time, the number of cars will be more and more. It is estimated that the number of cars in China has exceeded 30 million, and there are more than two cars per 100 Urban Households. These data show that China's automobile industry is developing rapidly. But relatively speaking, China's average car ownership is still very low, which is not commensurate with the level of China's economic development. If we want to reach the world's advanced level, there is still a long way to go. Therefore, the potential of the automobile market is still very large, and the development potential of the automobile transmission belt matching with the automobile is also very large. Agricultural machinery is similar to automobile industry. According to reports, China's current social ownership of various tractors, agricultural transport vehicles and harvesting machinery has approached 20 million. Although the possession is not small, but for China, a large agricultural country, the average possession is still quite low, and agricultural machinery must be developed. Therefore, the demand for various transmission belts for agricultural machinery will increase.

To sum up, it is expected that in a long period of time in the future, including the 11th Five Year Plan period, China's belt industry is still a period of sustained and stable development, and the domestic market prospect of both conveyor belt and transmission belt is good.

From the perspective of foreign market, it also provides development opportunities for China's belt industry. In recent years, the world economy has shown a trend of recovery, and the momentum of economic recovery in developed countries has exceeded expectations. Experts predict that the world economy will maintain a moderate recovery, which will have a greater positive impact on China's economy and foreign markets, and is conducive to the export of tape products. Since 2002, the export delivery value of adhesive tape in China has increased year by year, which shows this problem to some extent. In addition, after years of development, China's tape industry has basically had the ability to participate in the international market competition. As long as we further increase the development of marketable products and the improvement of product quality, and strive to open up the international market, we can fully occupy a larger share in the international market.

2.2 output forecast of main products in 2010

The average annual growth rate of conveyor belt products in China from 2001 to 2004 is 12.76%. If the growth rate is 10% in 2005, the national conveyor belt output will reach 110 million m2 in 2005. From 2006 to 2010, if the average annual growth rate is 7%, the national conveyor belt output will reach 150 million m2 in 2010. The average annual growth rate of China's V-belt products from 2001 to 2004 is 9.6%. If the growth rate is 7% in 2005, the national V-belt production will reach 940 million am in 2005. From 2006 to 2010, if the annual average growth rate is 5%, the national V-belt production will reach 1.2 billion am in 2010. In addition, there will be about 100 million V-belts and multi wedge belts for automobiles, about 10 million synchronous belts for automobiles and 30-40 million industrial synchronous belts and multi wedge belts.

2.3 demand of main raw materials in 2010

According to the above forecast, the industry needs 140000 tons of raw rubber, PVC and other elastomer materials in 2010, and 210000 tons of various additives including carbon black. The conveyor belt needs 53000 tons of core fabric, 14000 tons of steel wire, 14000 tons of polyester cord and cord for V-belt and 40000 tons of polyester cotton canvas.

3. Problems and suggestions

3.1 scientific development, focusing on efficiency

The continuous development of China's national economy, the recovery of the world economy, and the growth of global consumption of steel, energy, building materials, automobiles, and grain have brought good opportunities for the development of the belt industry. The belt industry should seize this development opportunity. However, the development of the belt industry should adhere to the scientific concept of development and pay attention to the growth of economic benefits. At present, China's tape production capacity, on the whole, is oversupply, large output and low economic efficiency. The belt industry should pay attention to the development of high-grade products with high technical content and limit the development of low-grade products with low technical content. Avoid the price war caused by the contradiction between supply and demand, and disrupt the tape market, affecting the economic benefits of the tape industry. Economic benefit is the feedback of the market on the overall quality of the enterprise, and it is also the ultimate goal of the enterprise. Without benefit, there is no need for the enterprise to exist in the market to a certain extent. In addition, in view of the relatively backward belt industry in the western region of China, attention should be paid to the development of the western region in terms of investment and layout.

3.2 independent innovation and market expansion

Nowadays, the advanced technology of adhesive tape is still in Europe, America and Japan. Compared with it, there are still some gaps in the technical level of adhesive tape in China. Although some of our country's tape products are exported every year, and there is a trend of increasing year by year, the technical content and price of the exported products are relatively low, and the benefit is relatively poor. On the contrary, in order to meet the demand of the domestic market, we have to import tape products with similar export delivery value every year, and the price of imported tape products is relatively high. Therefore, the fundamental way out for China's tape industry is to adhere to independent innovation and vigorously expand foreign markets. Belt enterprises should strengthen the development of core technology with independent intellectual property rights, strengthen the export advantage by enhancing the intrinsic added value of products and increasing brand benefits, so as to improve the export sales value and increase export benefits, and change extensive export into benefit oriented export; at the same time, strive to meet the needs of the domestic market and reduce imports as much as possible

3.3 develop circular economy, save and reduce consumption

The development of circular economy is an inevitable choice for the scientific development of China's rubber industry, especially in the current situation of high prices of raw materials, prominent contradiction between energy supply and demand, and low economic benefits of the industry, it is of great practical significance to vigorously improve the utilization rate of resources, save and reduce consumption, so as to improve the economic benefits of the belt industry. According to its own characteristics, the belt industry should take improving the utilization rate of resources, saving and reducing consumption, and developing circular economy as an important content of technological innovation and transformation. It is necessary to further optimize the structural design and compound formula design of the belt, so as to achieve the greatest economic and social benefits with the least resource consumption and environmental cost. The proportion of high strength conveyor belt with steel wire and synthetic fiber as core should be further increased to improve the service life of conveyor belt. V-belt should continue to promote polyester cord, improve service life and transmission efficiency. It is necessary to increase the development and application of thermoplastic elastomer. To develop the repair and renovation technology of adhesive tape. It is necessary to increase the recycling of solvents and the comprehensive utilization of waste gas and wastewater in the production process. In addition, we should try our best to realize the airtight rubber mixing, advocate the automatic weighing and airtight transportation of carbon black, additives and oil, so as to minimize the loss of raw materials, save and reduce consumption, and reduce environmental pollution

3.4 strengthen industry self-discipline and product quality supervision

At present, in the belt industry, it is a big problem in the production and operation of enterprises to reduce the price and compete for sales. In the face of non-standard market competition, the belt industry must take self-discipline action. It is necessary to give full play to the coordination and management role of industry associations and the supervision role of belt product quality supervision department on product quality. For the association, first, it is necessary to organize and carry out industry publicity activities to let users understand the tape industry; second, it is necessary to organize and carry out quality credit activities to support enterprises with good product quality and good reputation; third, it is necessary to carry out activities to cultivate famous brand products to improve the competitiveness of the industry; fourth, it is necessary to do a good job in enterprise coordination to guide enterprises not to engage in loss operation and disorderly competition. For the tape quality supervision and inspection department, first, it is necessary to cooperate with the association to do a good job in the tape product quality credit activities; second, it is necessary to strengthen the contact with the relevant departments, carry out regular spot checks on tape products, and report the spot checks to boycott inferior products; third, it is necessary to continue to implement the key product production license issuance system and product quality certification system
