FMS needle felt features:
1. Excellent thermal insulation: According to the physical principle, the thermal conductivity of the gas is small, and there are many air holes inside the excellent thermal insulation material. The glass fiber acupuncture cotton has innumerable tiny gas, and the fiber presents irregular arrangement, it is an excellent thermal insulation material, thermal conductivity coefficient is 0.2-0.040kcal/mhr. c between;
2. Will not burn: The main component of glass fiber is silicide (more than 50%), non-flammable, no deformation, no embrittlement, high temperature up to 7000C;
3. Sound absorption rate is good: When the sound wave invades the glass fiber cotton, the period energy will be inhaled in large quantities due to friction with the fiber and the size of the cavitation. In general, the sound absorption rate is as high as 90% or more, which is a good way to prevent noise interference.
4. High insulation: Glass fiber can withstand high temperature, good mechanical properties, and high chemical stability, is the best insulation material;
5. High corrosion resistance: glass fiber is not afraid of strong acid, strong alkali, will not reduce its functional characteristics for a long time;
6. Resilience: The glass fiber contains countless fixed air pockets and it has excellent resilience. Not afraid of any shock and vibration, the tensile strength is more than 1.0kg.
7. Low moisture absorption: The moisture absorption rate is usually close to zero.
8. Lightweight and soft: Compared with other heat insulation materials, the quality of glass fiber needle felt is the lightest and softest. If it is installed on the machine, it can reduce its weight and vibration load.
9. Easy construction: The size can be cut according to customers.
