Fiberglass Needle Felt Reasonable Structure And Good Performance

Fiberglass Needle Felt is a kind of new high-temperature filtration material with reasonable structure and good performance, which takes glass fiber as raw material and needles into felt. With three-dimensional pore structure, void, high rate, small resistance, dust removal efficiency more than fabric filter material, up to 99.9%. The filtration speed is about one times higher than that of fabric filter material. The filter material is suitable for high-temperature flue gas filtration in carbon black chemical industry, steel, metallurgy, coal-fired boilers, refractory materials and cement industries. Suitable for use in the bag filter with pulse cleaning and high speed reverse blowing. Through high temperature, corrosion medium long-term test, excellent performance, effective control of dust pollution, recovery of valuable micro-particles of products.

I. Excellent features

1. Good breaking heat: according to the principle of physics, the heat conduction rate of the gas is small, and there are many air holes in the excellent material. The glass fiber needle cotton has numerous fine gas, and the fiber presents irregular arrangement,Fiberglass Needle Felt is excellent thermal insulation, heat conduction coefficient 0.2~0.040kcal/mhr. C;

2, will not burn the main components of glass fiber is silicide (accounted for more than 50%), with non-flammable, no deformation, no embrittlement, high temperature up to 7000C;

3, sound absorption rate: When the ultrasonic invasion of glass fiber cotton, the energy will be due to the fiber and the size of the different cavitation friction, but is a large number of inhalation. Generally speaking,Fiberglass Needle Felt the sound absorption rate is up to more than 90%, is to prevent noise interference of the good;

4, High insulation: glass fiber capable of high-temperature, good mechanical, and chemical stability is high, is the best insulation material;

5, corrosion-resistant High: glass fiber is not afraid of strong acid, alkali,Fiberglass Needle Felt long time will not reduce its functional characteristics;

6, good recovery: Glass fiber contains countless fixed gas points, excellent recovery. Not afraid of any impact vibration, tensile strength of 1.0kg above.

7, low moisture absorption rate: Moisture absorption rate is usually close to zero.

8, light weight: soft and other insulation material comparison, glass fiber needle felt the lightest quality,Fiberglass Needle Felt most supple, if installed on the machine, can reduce its weight and vibration load.

9, simple construction: size can be cut according to customer.

II. Main uses:

1, for a variety of heat sources (coal, electricity, oil, gas) high-temperature equipment, central air-conditioning pipeline insulation;

2, for a variety of insulation, fire-retardant materials;

3, for special places of sealing, sound absorption, filtration and insulation materials;

4, for all kinds of heat transfer, thermal device insulation;

5, for vehicles, ships, aircraft and other parts of the sound insulation, insulation, heat resistance;

6, the car, motorcycle muffler inner core noise and engine silencing;

7, the color steel plate and the wood frame house interlayer interval thermal insulation;

8, thermal, chemical pipeline insulation, thermal insulation effect is better than general insulation materials;

9, air-conditioning, refrigerators, microwave ovens, dishwashers and other household electrical appliances wall Board insulation;

10, need insulation, heat insulation, fire, sound absorption, insulation of other occasions.

Suitable conditions:

The product can be used in 240 ℃ high-temperature long-term, short time temperature can reach 260 ℃, applied to steel, cement, electricity, non-ferrous metals,Fiberglass Needle Felt refuse incineration, asphalt concrete mixing, chemical industry and other industries of high-temperature flue gas filtration, suitable for pulse and high speed reverse blowing dust removal method, It is the most widely used filter material of high temperature bag filter at present.
