The production process of asbestos

The production process of asbestos-free gaskets has undergone some important innovations in recent years, and here are some key points:

The use of new materials:

Asbestos-free gaskets now use organic fibers such as aramidon and plant fibers, nitrile rubber and minerals as raw materials

. These materials provide better resistance to high temperatures, chemicals and environmental protection, while maintaining high strength and good resilience.

Pressing or copying process:

The production of asbestos-free gaskets involves pressing or copying processes that ensure uniformity and consistency of the gaskets. Through these processes, sealing products with superior permeability resistance can be produced.

Application of high temperature resistant synthetic fiber:

Some asbestos-free gasket products, such as CPS5220 asbestos-free sheet gasket, are made of high temperature resistant synthetic fibers, mineral fibers, special rubber and inorganic fillers by roller press vulcanization. This process improves the temperature resistance of the gasket, making it suitable for a wider range of industrial applications.

Short fiber reinforced rubber based sealing composite:

The development of asbestos-free short fiber reinforced rubber base sealing composites (NAFC materials), which are valued for their high temperature resistance (300 degrees Celsius), low creep, high strength and low cost characteristics. The technology transfer center of Nanjing University of Technology has developed the preparation technology of this material, and the preparation process is simple, and the production equipment of traditional CAF material is basically used.

Environmental and health considerations:

Since asbestos is recognized as a carcinogen, the use of asbestos materials and their products has been banned worldwide. Therefore, the production of asbestos-free gaskets takes into account not only performance, but also environmental protection and health factors.

Color stability and weather resistance:

During the production process, the color stability and weather resistance of the asbestos-free gaskets have also been improved. The outdoor durability of the product is improved through the selection of pigments and dyes with better light resistance, oxidation resistance, heat resistance, acid and alkali resistance, and the use of anti-aging additives.

Large-scale production:

Some internationally renowned enterprises have achieved the large-scale production of asbestos-free gasket materials, which not only improves production efficiency, but also reduces costs.

These innovations have resulted in significant improvements in the performance of asbestos-free gaskets, while also meeting the requirements of environmental protection and health, and promoting the wide application of asbestos-free gaskets in the global market.
