Standard Seals Industry Status

Industry status editor

In recent years, China's rubber seal products production and quality gradually into a new stage, the new period. However, these are far from being able to meet the needs of other industries to develop all kinds of rubber sealing products, serialized products, especially with the international advanced countries, China's products in terms of product quality, or in product varieties, are A considerable gap. This paper focuses on the concept, research content and research significance of sealing theory, summarizes the current situation of rubber seal, mechanical seal and packing sealing technology, and analyzes the relationship between China and the world's advanced technology in the research and development of advanced products Development capacity of the gap, and the future of China's future research areas of the focus of a number of recommendations.

China's seal industry's overall competitiveness is not strong

As we all know, in our country, the seal industry can be said to be the smallest industry, but the product can be used with large industrial use. Regardless of aviation, navigation, petroleum, chemical, or machinery, power generation, metallurgy, mining, etc., are inseparable from the seal. In short, all the organic, pump, tube, valve place, are dependent on the seal. So the industry is small, the surface is very wide involved.

In recent years, with the economic development, the development of sealing industry is also very fast. But unlike other industries, the development of sealed industry is fast, sealing business changes are slower. For example, the late 70s and early 80s, only in the river, Zhejiang, Lu has several manufacturers, and whether it is coastal, the mainland, or the south, north, everywhere visible seal factory, the entire seal industry from the previous few, To 300 as much, this development rate can be said to be very fast. But in terms of individual enterprises, many companies do not change, the scale of production is detour, and some even retrogression, science and technology not only did not increase the big, but in the weakened, many manufacturers still holding the "four old" , That is, old products, old technology, old equipment, the old scale. Of course, there are some enterprises, imitation of some of the ability to imitate a strong product, but in the entire industry with independent development of new business capacity is not much.

In terms of products, the vast majority of manufacturers or some spiral wound, packing ring, packing and high-strength gaskets and other old products. Slightly innovative polytetrafluoroethylene products, in technology and quality greatly lagged behind abroad, such as PTFE packing, expansion of PTFE belt. Looking around, few new products.

In terms of technical strength, the proportion of scientific and technical personnel in most enterprises is small. Many enterprises lack the technical personnel of genuine science class, and the technical force is weak, so the enterprise lacks the corresponding development and transformation ability. Since the establishment of the European Union, the joint brought about by the strong, to promote the EU to raise and establish a new European seal quality standards, replacing the previous dependence on the American Fluid Association to develop a series of standards. The leakage rate is present and emphasized in the new European sealed quality standards. China's product leakage rate is generally 10-1mg / s level, while Europe has emerged a leakage rate of 10-4mg / s-class high-strength graphite composite board!
