The selection of glass fiber casing is more important, so today I will talk about the knowledge of glass fiber casing selection in detail:
1. The primary task of preparing high-performance carbon fiber is to achieve high purification, high strengthening, densification and smooth surface of the raw silk. The carbon fiber system engineering needs to start with the polymerization monomer of the raw yarn to realize one-stop production. The quality of the raw silk not only determines the properties of carbon fiber, but also restricts its production cost. High-quality pan strands are the primary prerequisite for manufacturing high-performance carbon fibers.
2. In the pre-oxidation process, under the premise of ensuring homogenization, the pre-oxidation time should be shortened as much as possible. This is a directional issue for reducing production costs. Research high-temperature technology and high-temperature equipment and related important components. The high temperature carbonization temperature is generally 1300～1800℃, and the graphitization temperature is generally 2500～3000℃. Operating at such a high temperature requires continuous operation and the service life of the equipment. Therefore, it is extremely important to study a new generation of high-temperature technology and high-temperature equipment. Such as microwave, plasma and induction heating under inert gas protection and oxygen-free conditions.
3. Minimization of impurity defects is a fundamental measure to improve the tensile strength of carbon fiber, and it is also a hot topic for scientific and technological workers. In a sense, the process of increasing strength is essentially a process of reducing and reducing defects.
In addition, a good glass fiber casing also has the advantages of high strength, light weight, corrosion resistance, acid and alkali resistance, creep resistance, and high temperature resistance.
