Overview of Fiberglass

2023-03-09

Glass fiber is made of SiO2, which melting point is 1720°C. SiO2 is also the basic element of quartz, quartz is crystalline, and its SiO2 content is greater than or equal to 99% (when SiO2 is heated to 1200 ° C, and then cooled in the environment, it will crystallize into quartz). Glass is produced by varying the temperature and cooling rate. Crystallization can be prevented if pure SiO2 is heated to 1720°C and then rapidly cooled. Through continuous improvement and innovation, today's fiberglass manufacturers have combined this strategy of high temperature and rapid cooling with other steps, although the process is essentially the same as that developed in the 1930s, but with a much larger scale. The manufacturing process of glass fiber can be divided into five basic steps: batching, melting, fiberization, sizing and drying.

Metal Expansion Joints vs Fabric Expansion Joints

2023-03-09

For many years, fabric expansion joints have been the preferred type of joints in the power industry and pipeline fields due to their excellent high temperature resistance, corrosion resistance, sealing, insulation, noise reduction and shock absorption, and easy installation. Compared with metal expansion joints, fabric expansion joints are more cost-effective and have greater advantages in terms of price cost, service life, displacement performance, load transmission, maintenance cost, and replacement cost.
