Glass Fiber Knitwear

Product Features

1. Good thermal insulation: According to physical principles, the thermal conductivity of gas is small, and there are many air pockets inside the excellent thermal insulation material. Glass fiber needle-punched cotton has countless fine gases, and the fibers are arranged irregularly. It is an excellent thermal insulation material with a thermal conductivity coefficient of 0.2-0.040kcal/mhr. between c;
2. No burning: The main component of glass fiber is silicide (accounting for more than 50%), which is non-combustible, non-deformable, non-brittle, and can withstand high temperatures up to 700°C;
3. Good sound absorption rate: When sound waves invade glass fiber cotton, its energy will be absorbed in large quantities due to friction with fibers and air pockets of different sizes. 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 temperatures, and has good mechanical properties and high chemical stability, so it is the best insulating material;
5. High corrosion resistance: glass fiber is not afraid of strong acids and alkalis, and will not reduce its functional characteristics for a long time;
6. Good recovery: the glass fiber contains numerous fixed air pockets, and the recovery is excellent. Not afraid of any impact and vibration, the tensile strength is above 1.0kg.
7. Low moisture absorption rate: The moisture absorption rate is usually close to zero.
8. Light and soft: Compared with other heat insulation materials, 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. Simple construction: the size can be cut according to the customer.

The main product usage
Medium and non-alkali expanded glass fiber filter cloths (bags) are widely used in dust and air filtration in industries such as iron and steel, electric power, metallurgy, chemical industry, environmental protection, and cement.

Other product usages

Glass fiber needle felt can be used for sound insulation, sound absorption, shock absorption, flame retardancy, etc. Various bag-type dust collectors for flue gas purification and dust recovery in metal, chemical, incineration and other industries.
1. Used for heat preservation of various heat sources (coal, electricity, oil, gas) high-temperature equipment, and central air-conditioning pipelines;
2. Used in various heat insulation and fireproof materials;
3. Sealing, sound-absorbing, filtering, and insulating materials used in special places;
4. Used for heat preservation of various heat transfer and heat storage devices;
5. It is used for sound insulation, heat insulation, and heat resistance of vehicles, ships, airplanes, and other parts;
6. For the sound insulation of the inner core of the muffler of automobiles and motorcycles and the noise reduction of the engine;
7. Colored steel plates and interlayers of wood-structured houses are insulated from heat and heat;
8. Thermal and chemical pipeline insulation, the thermal insulation effect is better than that of general thermal insulation materials;
9. Heat insulation and heat preservation of electrical wall panels in household industries such as air conditioners, refrigerators, microwave ovens, and dishwashers;
10. Other occasions that require heat preservation, heat insulation, fire prevention, sound absorption, and insulation.

Operating conditions
Long-term use is 200°C-280°C, the best use temperature is 90°C-220°C, the working temperature of the FCA formula should be less than 180°C; the filtration wind speed should be less than 0.8m/min.
