Characteristics of fiberglass chopped strand mat
Fiberglass chopped strand mat is a kind of advanced felt with insulation, heat insulation, fire prevention, noise reduction, air purification, etc. after glass fiber is cut into a certain length, it is made through the processes of filament separation, pile forming and needle punching.
Characteristics of fiberglass chopped strand mat:
1. Good heat insulation: according to the physical principle, the heat conductivity of the gas is small, and the excellent heat insulation material has many air holes inside. The glass fiber needle punched cotton has numerous fine gases, and the fibers are arranged irregularly. It is an excellent thermal insulation material with a thermal conductivity of 0.2-0.040kcal/mhr.
2. No combustion: the main component of glass fiber is silicide (more than 50%), which has no flammability, no deformation, no embrittlement, high temperature resistance up to 7000c;
3. Good sound absorption rate: when the sound wave invades the glass fiber cotton, the period energy will be inhaled by a large amount due to the friction with the fiber and different size of air cavity. Generally speaking, the sound absorption rate is as high as 90%, which is a good talent 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 and alkali, and its functional characteristics will not be reduced for a long time;
6. Good recovery: glass fiber contains numerous fixed air holes, excellent recovery. The tensile strength is more than 1.0kg.
7. Low moisture absorption: moisture absorption is usually close to zero.
8. Light weight and soft: compared with other thermal insulation materials, glass fiber needle felt is the lightest and most flexible. If installed on the machine, it can reduce its weight and vibration load.
9. Simple construction: the size can be cut according to customers.
Application of fiberglass chopped strand mat:
1. It is used for heat preservation of various heat sources (coal, electricity, oil, gas) high temperature equipment and central air conditioning pipeline;
2. Used for all kinds of heat insulation and fireproof materials;
3. Sealing, sound absorbing, filtering and insulating materials for special places;
4. It is used for heat preservation of various heat transfer and heat storage devices;
5. It is used for sound insulation, heat insulation and heat insulation of vehicles, ships, aircraft and other parts;
6. The sound insulation of the inner core of automobile and motorcycle muffler and the noise elimination of engine;
7. The interlayer thermal insulation of color steel plate and wood structure buildings is also discussed;
8. Thermal and chemical pipeline insulation, thermal insulation effect is better than general insulation materials;
9. Heat insulation and heat preservation of wall panels of household appliances such as air conditioner, refrigerator, microwave oven, dishwasher, etc;
10. Other occasions requiring heat preservation, heat insulation, fire prevention, sound absorption and insulation.
