Glass Fiber Needle mat

Fiberglass needle mat is a kind of rational structure, performance, good filter material, with glass fiber as raw material, after combed with thorn for short cut glass fiber needle felt, felt with mechanical method between layers of glass fiber, glass fiber mat layer and mutual entanglement between fiber reinforced fiberglass cloth, fabric is strengthened and blanket made of nonwoven filter material.



Characteristics

Glass fiber monofilament disorderly crisscross penetration, assumes the astatic three-dimensional microporous structure, small space, space law, has a good sound-absorbing, shock, corrosion resistance, insulation, high temperature resistant, flame retardant performance. High porosity, small gas filtration resistance and filtration velocity, high dust removal efficiency, at the same time, bending resistance, abrasion resistance, dimension stability of glass fiber needle felt mainly for manufacturing
The main features



1, hot resistance: according to the principle of physics, the thermal conductivity of the gas is small, good break hot material internal has many air holes. And glass fiber needle-punched cotton with countless small gas, an irregular arrangement, and fiber for excellent heat insulation materials, heat transfer coefficient is 0.2 ~ 0.040 kcal/MHR. C;

2, not combustion, the main components in glass fiber silicide (50% above), incombustible, no deformation, no embrittlement, high temperature resistant up to 7000 c;

3, good sound-absorbing rate: when sonic into glass fiber cotton, phase of the energy due to friction with the size of fibers and different air pockets, and be inhaled in large quantities. In general, the acoustic absorption rate is as high as 90% above, is to prevent noise interference LiangCai;

4, high insulation, high temperature glass fiber ability, good mechanical, and chemical stability high, is the best insulation material;

5, high corrosion resistance, not afraid of strong acid, strong alkali glass fiber, long time will not reduce its features;

6, good resilience: glass fiber containing numerous fixed air pockets, and excellent resilience. Not afraid of any impact vibration, tensile strength of more than 1.0 kg each.

7, low moisture absorption rate, moisture absorption rate is usually close to zero.
Eight, light weight and soft: compared with other thermal insulation materials, the quality of the glass fiber needle felt the most light and soft, if installed on the machine, can reduce the weight and the vibration load.

Applications

Glass fiber needle felt can be used in the automotive industry in sound insulation, sound-absorbing, shock absorption, flame retardant, etc., mainly used in industrial filtration in the field; High temperature flue gas filtration; Glass fiber needle felt is widely used in carbon black, steel, non-ferrous metal, chemical, incineration flue gas purification and other industries of the dust and recycling all kinds of bag filter.

1, used for various heat sources (coal, electricity, oil, gas) high temperature equipment, central air conditioning pipe heat preservation;

2, used in a variety of insulation, fireproof materials;

3, seal used in special places, sound-absorbing, filtering and insulating materials;

4, heat transfer and heat storage devices used in all kinds of insulation;

5, for cars, boats, aircraft parts, such as sound insulation, thermal insulation, heat resistance;

6, for car, motorcycle muffler deadened the sound insulation and inner core engine;

7, color steel and wood structure building is sandwiched between layers of heat insulation heat preservation;
