Glass fiber needle-punched Mat/Felt

Glass fiber needle-punched Mat/Felt is a new high-temperature filter material with reasonable structure and excellent performance. It uses glass fiber as raw material to be needle-punched into felt. It has a three-dimensional pore structure, voids, high rate, low resistance, and the dust removal efficiency exceeds that of the fabric filter, which can reach 99.9%. The filtration speed is about twice as high as the fabric filter material. The filter material is suitable for high-temperature flue gas filtration in industries such as the carbon black chemical industry, steel, metallurgy, coal-fired boilers, refractory materials, and cement. It is suitable for pulse cleaning and high-speed back-blowing bag filters. After the long-term test of high temperature and corrosive media, it has excellent performance, effectively treats dust pollution, and recovers products with valuable fine particles.

1. Excellent features 1. Good thermal insulation: According to physical principles, the thermal conductivity of gas is small, and excellent thermal insulation materials have many air pockets inside. The glass fiber needle-punched cotton has countless fine gases and irregularly arranged fibers. It is an excellent thermal insulation material with thermal conductivity of 0.2~0.040kcal/mhr.;

2. The main component of the glass fiber that will not burn is silicide (more than 50%), which is non-combustible, non-deformable, non-embrittle, and has a high-temperature resistance of 7000C;

3. Good sound absorption: when sound waves penetrate into the glass When fiber cotton is used, a large amount of energy will be absorbed 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 temperature, good mechanical properties, and high chemical stability, which is the best insulating material;

5. High corrosion resistance: The glass fiber is not afraid of strong acids and alkalis, and will not reduce its functional properties 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: soft Compared with other heat insulation materials, fiberglass needled felt is the lightest and most flexible. If installed on a machine, it can reduce its weight and vibration load.

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


Main uses: 

1. Used for heat preservation of various heat sources (coal, electricity, oil, gas) high-temperature equipment and central air-conditioning pipes;

2. Used for various heat insulation and fireproof materials;

3. Used for sealing in special places, Sound-absorbing, filtering and insulating materials;

4. used for heat preservation of various heat transfer and heat storage devices;

5. used for sound insulation, heat insulation, and heat resistance of cars, ships, airplanes and other parts;

6. for automobiles and motorcycles The sound insulation of the inner core of the muffler and the silencer of the engine;

7. The thermal insulation of the interlayer of the colored steel plate and the wooden structure house;

8. The thermal and chemical pipeline insulation and the thermal insulation effect is better than general thermal insulation materials;

9. The air conditioner, refrigerator, microwave oven, Dishwasher, and other household electrical appliance wall panels;

10. Other occasions where heat preservation, heat insulation, fire prevention, sound absorption, and insulation are required.


Suitable working conditions:

The product can be used for a long time at a high temperature of 240℃, and can withstand a temperature of up to 260℃ in a short time. It is used in steel, cement, electric power, non-ferrous metals, garbage incineration, asphalt concrete mixing, chemical industry and other high-temperature flue gas filtration. It is suitable for a pulse and high speed. The back-blowing dust removal method is currently the most widely used filter material for high-temperature bag filters.
