Fiberglass can be divided into alkali-free fiber, medium-alkali fiber,high-alkali fiber, special glass fiber, etc. according to the alkali content in its composition. The first three kinds of fibers are commonly used in wet-laid felt. alkali-free glass fiber is suitable for epoxy copper clad laminates and electrical insulation products. Read More

Polyester glass fiber cloth has been widely used in bridge construction because of its high strength, high temperature stability, good chemical stability and other characteristics. In the process of application in bridge engineering, the application of polyester glass fiber cloth in the specific construction stage needs comprehensive design and comprehensive management from several aspects such as construction preparation, construction process and post-construction control. Only in this way can we ensure that the effect of polyester glass fiber cloth technology can be fully played out. Read More

In recent years, the environm​ental protection standards set by the government have become increasingly strict, and the contradiction between supply and demand of global water resources has gradually intensified. The application and development of reverse osmosis membrane technology in the field of water treatment has ushered in new opportunities. It has good applications in water treatment fields such as domestic sewage, textile printing and dyeing industry wastewater and landfill leachate. Read More

In the process of "white and black" reconstruction, a thin stress absorbing layer on the rigid base can effectively prevent the appearance of reflection cracks. The traditional geotextile stress layer has a certain waterproof ability, but when the spreading temperature of the hot asphalt mixture exceeds 160℃, the geotextile has poor strength and creep resistance, so it can not play the reinforced anti-cracking effect. Glass fiber grating and asphalt mixture can form the effect of extrusion. Read More
