Glass fiber needle pad quality identification method and application range
Glass fiber pin pads are often used for thermal insulation of equipment and play a very important role in the industrial industry. So how to identify the quality of the fiberglass pin cushion? Where can the fiberglass pin cushion be applied? Next, the editor will discuss with you the quality identification method and application range of the glass fiber pin cushion, and I hope to help everyone.
Glass fiber needle pad quality identification method
First of all, the understanding of the formation of the glass fiber pin cushion is made by using a needle punching process to make the fiber-like heat-insulating cotton into a blanket shape, which can be distinguished from the appearance, and whether the appearance is contaminated with impurities or the like.
Secondly, the tensile properties of the glass fiber pin cushion are tested, because the good quality glass fiber pin cushion has a certain toughness, and if there is a falling phenomenon during the pulling process, the quality is problematic.
Then, you can also distinguish the color, the product with yellowish color, the quality will be slightly worse.
Finally, the quality of the glass fiber pin cushion is determined by measuring the volume according to the test standard, such as about 100 kg per cubic centimeter. These identification methods are suitable for users to use in the field, can probably identify the quality of the fiberglass pin cushion, but it is inevitable that there will be omissions, more professional identification methods need to go to the formal inspection unit to detect.
Glass fiber needle pad application range
Glass fiber pin cushion is made of ceramic fiber as raw material, processed by processing, light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat and mechanical vibration resistance. It is specially used for various high temperature. , high pressure, easy to wear environment. It is an excellent refractory material. It has the advantages of light weight, high temperature resistance, small heat capacity, good thermal insulation performance, good high temperature insulation performance and no toxicity. The application of glass fiber pin pads is mainly in the processing industry and heat treatment industry (industrial furnaces, heat treatment equipment and other thermal equipment). Ceramic fiber consumption in the processing industry and heat treatment industry accounts for 40% of the production of glass fiber pin cushions, followed by the steel industry, which consumes 25% of the fiberglass needle pad production.
The above is about the quality identification method and application range of glass fiber pin cushion. I hope that everyone can understand the quality identification method and application range of glass fiber pin cushion, and it is helpful for everyone to use fiberglass pin cushion.
