seal industry development present situation
Hebei sponge foam strip wholesaleSmall make up Tell you seal industry development present situation
In recent years, the production and quality of rubber seal products gradually into a new stage, new period. But, these are far from satisfied only other businesses of all kinds of rubber seal products standardization, seriation product needs, especially compared with the international advanced countries, our country product no matter in the quality of the product, or in terms of product varieties, all have a considerable gap. This hundred BBS expounds the seal to learn the concept, research content and research significance, rubber seal, mechanical seal, and summarized the present situation of the packing seal technology, analyzes the sealing technology with the world advanced research level and ability of new product development in developed countries the gap, and the sealing areas in our country in the future research focus on some Suggestions are put forward. Seal industry overall competitiveness is not strong in China as we all know, in our country, sealing industry is the smallest industry, but can be used with great industrial products. Aviation, Marine, petroleum, chemical, and mechanical, electricity, metallurgy, mining, etc., are inseparable from the seal. In short, where the organic, pump, pipe, valve, all depends on the seal. So the industry is small, plane is involved. In recent years, with the development of economy, the seal industry development also soon. But unlike other industries, the sealing industry development is fast, seal company change is slow. In the late 70 s and early 80 s, for example, in jiangsu, zhejiang, shandong only several manufacturers, and both coastal and inland, or south, north, everywhere seal factory, the seal industry has been developed from previous several development to more than 300, the development speed is fast.
But in terms of individual enterprises, many enterprises havent changed much, weave the scale of production, or even reverse, the power of science and technology not only has no major increase, some in unmarried, many manufacturers are still holding the "old four", namely the old products, old technology, equipment, scale. Of course, there are some companies, strong ability to generic copy some products, but have the independent ability to develop new products in the industry enterprises. In terms of its products, the vast majority of manufacturers or some winding gasket, packing ring, packing and high strength gasket and other old products. Slightly new ptfe products, in terms of technology and quality greatly lags behind that of foreign countries, such as ptfe packing, expanded ptfe tape. Throughout all round, very few new products. In terms of technology, most of the smaller proportion of science and technology personnel, and many enterprises lack of original trained technical personnel, technical force is weak, so enterprises lack ability of development and reform. Since its inception the European unio, combined with powerful, get the eu to improve and establish the new European sealing quality standards, instead relying on the American association of fluid formulated a series of standards. In the new European sealing quality standards and emphasize the leakage rate. Our country product leakage rate is in commonly 10-1 mg/s level, Europe has been leakage rate of 10-4 mg/s of high-strength graphite composite board! In terms of equipment, the vast majority of companies have only a few old clay of the winding machine, knitting machine, several simple tooth machine and shearing machine, etc., depends on the workers ability to organize production. While many manufacturers of equipment production task unsaturated state for a long time.
