"The airbag wire for car nylon airbags and the nylon thread for women's LV bags are all produced by us." On February 19, in the enterprise exhibition hall, Wang Hailun, deputy general manager of Zhongwei Chemical Fiber Co., Ltd. (hereinafter referred to as "Zhongwei Chemical Fiber"), introduced it. The company he works for, located in Hebiqi County, is the only private enterprise in China that can produce nylon airbag silk.
The airbag wire in Helen Wang's mouth is a high-end nylon material - nylon 66. Compared with traditional polyester industrial yarn, nylon wire has higher strength, melting point and better friction resistance.
For a long time, the production process and technology of nylon 66 automotive airbag wire have been firmly controlled by multinational giants, and there are only six automotive airbag filament manufacturers in the world, such as INVISTA in the United States, PHP in Germany, and Toray in Japan. "We're just going to make products that nobody else can do." Wang Hailun said that Zhongwei Chemical Fiber, together with well-known experts in the industry and at home and abroad, has successfully developed and mastered the core production technology of nylon 66 automotive airbag wire, filling the gap in the domestic automotive airbag wire market and greatly reducing the production costs of downstream enterprises. At present, its production of nylon airbag wire has reached a market occupancy rate of 20%.
In the production workshop of Zhongwei Chemical Fiber, nylon wire with a diameter of less than one-third of the diameter of a hair strand is melted and pulled at high temperatures, "This production principle is like we make vermicelli." Wang Helen made an analogy.
In addition to being applied to airbags, the nylon wire developed and produced by Zhongwei Chemical Fiber has been applied to military clothing, fire suits, bags, high-speed rail special gauge baffles, gauge blocks, buried casings, baffle seats and other series of products, achieving a breakthrough of zero for domestic private enterprises. "The 'Fine Dan High Strength Nylon 66 Fiber' developed by us is also used in the party flag and four huge banners guarded by the air flag guard echelon at the celebration of the 100th anniversary of the founding of the party." Wang Helen said.
Why can we break the monopoly of foreign nylon wire manufacturers? Wang Helen introduced that among them, there is a key intermediate, that is, adiponitrile, which is the key organic matter for the synthesis of nylon 66, "We have completed the synthesis of adiponitrile to nylon 66 through technology research and development. What makes Wang Helen even happier is that in March this year, the mainland's domestic production of adiponitrile enterprises will be officially put into production, not to be "stuck neck" by foreign companies, at that time, the production capacity of nylon wire will be further expanded, more applications to the market.
"Dig one meter wide and 100 meters deep." Wang Helen said that the nylon industry has trillions of yuan in the future market prospects, they will also be the application of nylon 66 subdivision to the extreme, with scientific and technological innovation to drive comprehensive innovation, open up more application categories, "We also believe that in the future, more nylon material products can also enter the vision of ordinary people, no longer mysterious." ”
