alkali-free glass fiber chopped strands will further increase


Sep 20,2022


As a new type of material with superior performance and strong substitution, E-glass fiber chopped strands are suitable for many fields in the national economy. Although my country is the largest country in glass fiber production, a large part of it is used for export, and the downstream application field of domestic glass fiber still needs to be further developed. Statistics show that the annual consumption of glass fiber per capita in developed countries such as the United States and Japan reaches 4.5 kilograms, while the annual consumption of glass fiber per capita in my country is only 0.6 kilograms. In the future, the domestic market has great potential for improvement.

 The construction investment of alkali-free chopped glass fiber kiln production kiln is large, and the industry is capital-intensive, technology-intensive, and labor-intensive, with high industry barriers. In order to curb the low-level repetitive construction and blind expansion of the glass fiber industry and promote the upgrading of the industrial structure, the "Access Conditions for the Glass Fiber Industry", which was implemented by the state on February 1, 2007, has a Consumption, environmental protection and other aspects have put forward clear requirements, which has raised the entry threshold of the glass fiber industry. In the future, with the acquisition and merger of domestic glass fiber production enterprises, the industry concentration will further increase.

Rigorous testing of alkali-free chopped glass fiber filaments:

   No opaque unmelted material is allowed in the alkali-free chopped glass fiber filaments, and poor fusion and bonding between the two glass bodies are not allowed. Visual inspection of the brick body should not have ripples, bubbles and layered streaks caused by inhomogeneity in the glass body. The inner concave of the large outer surface of the glass brick should be less than 1 mm, and the outer convex should be less than 2 mm.

   The inspection of alkali-free chopped glass fiber should not only be tested according to the requirements of flat glass, but also its processing quality should be inspected to check whether the specifications and dimensions are standard, whether the processing accuracy and pattern clarity meet the requirements, and the edges are not allowed to have defects.

Alkali-free chopped glass fiber filament promotes energy saving and emission reduction:

By mastering the core technology of alkali-free chopped glass fiber reinforced composite materials, the batch production of alkali-free chopped glass fiber material for auto parts has become a reality, and may partially replace steel parts. Alkali-free chopped glass fiber is an inorganic non-metallic material, which has advantages over traditional materials in terms of strength, elasticity, corrosion resistance and wear resistance. Compared with traditional materials, auto parts made of alkali-free chopped glass fiber are lighter in weight. Under the same conditions, the weight of parts using composite materials is only 1/3 of that of traditional materials. However, due to the current technology and cost of composite materials, the proportion of domestic vehicle accessories only accounts for 8% to 12%, while foreign vehicles account for 20% to 30%. The use of this composite material to replace traditional steel is in line with the trend of lightweight development of automobiles. It is expected that in 5 to 10 years, this material will be widely used in auto parts. Such as car seats, bumpers, tray brackets and other accessories, will replace steel, the use of alkali-free chopped glass fiber reinforced composite materials, will reduce the weight of the car, promote energy saving and emission reduction.
