Introduction to the characteristics and production process of glass fiber mat

一、Various characteristics of glass fiber mat

  Glass fiber felt is a high-grade felt with insulation, heat insulation and fire prevention, noise reduction, air purification and other properties made by cutting composite fibreglass into a certain length, and then making through the processes of splitting, velvet, and acupuncture.

  Glass fiber mat features:

  1. Good thermal insulation: According to the physical principle, the thermal conductivity of gas is small, and there are many air pockets inside the excellent thermal insulation material. The glass needle mat has countless tiny gases, and the fibers are irregularly arranged. It is an excellent thermal insulation material with a thermal conductivity of 0.2 to 0.040kcal/mhr.

  2. It will not burn: the main component of glass fiber is silicide (more than 50%), which is non-flammable, non-deformable, non-brittle, and resistant to high temperature up to 7000C.

  3. Good sound absorption rate: When the sound wave penetrates into the glass fiber cotton, the period energy will be inhaled in large quantities due to the friction with the fibers and air pockets of different sizes. Generally speaking, the sound absorption rate is as high as 90% or more, which is a good talent to prevent noise interference.

  4. High insulation: ar fibreglass can withstand high temperature, has good mechanical properties, and has high chemical stability, which is the insulating material of hao.

  5. High corrosion resistance: glass fiber is not afraid of strong acid and alkali, and its functional properties will not be reduced for a long time.

  6. Good recovery: The glass fiber contains numerous fixed air pockets, and the recovery is excellent. Not afraid of any shock and vibration, the tensile strength is above 1.0kg.

  7. Low moisture absorption rate: The moisture absorption rate is usually close to zero.

  8. Lightweight and soft: Compared with other thermal insulation materials, Fiberglass Needle Mat is light and soft. If it is installed on a machine, it can reduce its weight and vibration load.

  9. Simple construction: the size can be cut according to customers.
