Speaking of fiberglass every day, what exactly is fiberglass?
1. Definition of fiberglass Glass fiber reinforced plastic (also known as glass fiber reinforced plastic, symbol GFRP or FRP) is a composite material that uses glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as reinforcement materials and synthetic resin as the matrix material. The concept of composite materials refers to a material that cannot meet usage requirements and needs to be composed of two or more materials to form another material that can meet people's requirements, namely composite materials. Due to the different types of resins used, they are ref

The main types and functions of common flame retardants
Flame retardants are functional additives that endow flammable polymers with flame retardancy. They are mainly designed for the flame retardancy of polymer materials. Gas asphyxiation, etc. Most flame retardants achieve the purpose of flame retardancy through the joint action of several mechanisms. endothermic effect The heat released by any combustion in a short period of time is limited. If a part of the heat released by the fire source can be absorbed in a short period of time, the temperature of the flame will decrease, radiate to the combus
Causes of foaming of epoxy resin glue and methods of eliminating bubbles
Causes of bubbles produced in the stirring process: The reason why bubbles are produced in the mixing process of epoxy resin glue is firstly the bubbles caused by the gases brought into the mixing process, and the "cavitation effect" caused by the liquid with too fast stirring speed. However, there are two kinds of bubbles visible to the naked eye and invisible ones. Using vacuum defoaming can only eliminate the bubbles visible to the naked eye, which is not good for removing the tiny bubbles invisible to the huma
Introduction and Main Characteristics of Squeezed Grille
The extruded fiberglass grille has most of the characteristics of the molded fiberglass grille. But there are also significant differences, the most important of which is the high glass fiber content (65% -70%) in the direction of the load-bearing strip, making it more advantageous to use it in large spans compared to molded fiberglass gratings. This will reduce the foundation support and reduce engineering costs. Chemical resistance Select excellent ortho benzene, meta benzene, vinyl resins, and extruded fiberglass gratings with surface felt, which have
