Product name: BTT-NY4200 non-asbestos rubber fiberboard

product description:

Introduce the two concepts of non-asbestos board from both the broad sense and the narrow sense. The former refers to all non-asbestos boards, such as red steel paper, oil-resistant fiber paper, ordinary rubber boards, etc., which can be called asbestos-free boards. In a narrow sense, non-asbestos boards only refer to the initial use of asbestos fibers as reinforcing fibers or insulating materials.

The products mainly use nitrile rubber and natural rubber as adhesives, non-metallic materials as fillers, and organic and inorganic fibers as frames. Rolled by a sheet forming machine.

Conventional colors: blue, green, other colors can be customized.

Specification size: 1520*4100mm, 1520*4600mm, 1270*3810mm, can be cut into small pieces

Conventional thickness: 0.4-5.0mm, boards above 5.0mm can be bonded

However, with the improvement of environmental protection requirements, materials produced from asbestos fibers such as aramid and acrylic fibers have been replaced by other wide-ranging high-performance fibers. These high-performance fibers are collectively referred to as non-asbestos boards and are further classified as non-metallic and non-metallic materials. Seal it. Asbestos sealing board and non-asbestos calcium silicate board for heat insulation. They are very good insulating materials. It is ideal in terms of high temperature resistance. It can be used normally at high temperatures.

Non-asbestos rubber fiberboard performance parameters index: transverse tensile strength ≥ 6Mpa, leakage rate ≤ 1.0ml/min, compression rate 7-17%, rebound rate ≥ 40%, qualified oil resistance, large instantaneous temperature resistance 200 ℃, continuous Use temperature resistance 150℃.

Inspection standard: Rolling method non-asbestos fiber gasket (JC/T2052-2011)

Expensive gaskets may not be suitable. Especially non-asbestos boards are made by mixing inorganic fibers or organic fibers with rubber. Different fibers are mixed with different rubbers, and the applications are also very different. For example, gaskets made of aramid fiber and nitrile rubber are more versatile and more expensive than vegetable fiber gaskets made of plant fiber and animal glue, but under certain conditions, such as: reducer , The gear uses plant fiber. When the temperature of the storage tank is not high, the pressure is not high and grease is used, the gasket is economical and the price is reasonable.

Remarks: The product can be coated with graphite and anti-sticking agent according to customer requirements, and metal wires can be clamped with a thickness of 0.8mm or more; gasket materials with a thickness greater than 3.0mm are not subject to transverse tensile strength test; gasket materials reinforced by wire mesh are not Do transverse tensile strength and nitrogen leakage rate tests.
