How does the flame retardant rubber-plastic insulation pipe distinguish the fire rating?

The main feature of the rubber and plastic insulation pipe is the closed foam structure, which has small thermal conductivity; it has excellent heat insulation effect and can save energy consumption: the closed bubble structure and the dense skin make the water vapor difficult to penetrate, and the water absorption rate is low; the product is soft. Sex, construction and installation is very convenient, saves labor and materials; elegant appearance; wide temperature range (-40 ° C to 120 ° C), good fire resistance, durable; unique flame retardant formula, the material has excellent fire retardant effect.
1. The closed-cell structure can effectively prevent heat conduction, and the thermal conductivity does not exceed 0.034 W/m?k at 0 °C.
2, the surface heat release coefficient is high, reaching 9W/m2k
3, with excellent resistance to water vapor permeability, moisture resistance μ ≥ 5,000 constitute a "built-in" waterproof vapor layer, so that the insulation board as a whole is both insulation and moisture barrier.
4, fire performance aerobic index of 32 or more, installation is simple and fast, does not contain CFC, HFC or HCFC and other fluorine-containing hydrocarbon materials do not contain formaldehyde, dust and fiber.
5, rubber and plastic insulation pipe has excellent resistance to water vapor permeability, moisture resistance 5,000 is both insulation and moisture barrier;
6. Fluorine-free hydrocarbon materials such as CFC, HFC or HCFC are free of formaldehyde, dust and fiber;
7, rubber and plastic insulation pipe has excellent fire performance. It is a Class B1 flame retardant material and its temperature range is from -50 °C to 110 °C.
Rubber and plastic insulation materials have high elasticity, which can greatly reduce the vibration and resonance of chilled water and hot water pipes during use. Rubber and plastic insulation materials are very stable in use. Under the same conditions, the thermal conductivity of water is 24 times higher than that of air. If the material of the non-closed structure is damaged, the water vapor can penetrate into the interior of the material and guide it safely, which will not irritate the skin, ie it will not harm. health. They prevent mold growth from pests or rats, and are resistant to acids and alkalis. These properties make rubber and plastic an ideal insulation material for protecting pipes from corrosion due to atmospheric media or industrial environments. Indoor and outdoor hot water piping systems, such as hospitals, houses, factories, etc., use rubber and plastic insulation materials to reduce their heat loss. In addition, rubber and plastics have proven to be the ideal insulation material for indoor and outdoor pipes used in solar heating systems. The rubber-plastic insulation material has a perfect closed-cell structure. All the cells are independent of each other, and the bubbles that are not connected to each other form a closed air layer, which effectively improves the thermal insulation performance of the product. At the same time, the rubber-plastic independent plastic insulation material can effectively reduce the heat. loss. In addition, rubber and plastics have proven to be the ideal insulation material for indoor and outdoor pipes used in solar heating systems. The closed bubble structure of rubber and plastic can form multiple barriers to water vapor molecules. Even if the surface of the material is damaged, it can prevent water vapor from penetrating into the interior of the material, thus maintaining the heat insulation effect of the product. The rubber and plastic insulation material is a high quality insulation. Material, water vapor resistance is an important factor affecting its service life. Therefore, it is necessary to test the water vapor permeability of rubber and plastic insulation pipes, which is one of the indicators that related enterprises must pay attention to and control. The use of good insulation measures and insulation materials in construction and industry can significantly reduce production energy consumption and cost, improve the environment, and achieve twice the result with half the effort. In the late 1970s, some developed countries in foreign countries began to use rubber and plastic insulation materials in building energy conservation, and achieved great results, and building energy consumption dropped drastically. For example, in Denmark, after using rubber and plastic insulation materials, the heating area increased by 30% in 1985 compared with 1972, but the heating energy consumption was reduced by 3.18 million tons of standard coal. Significant social and economic benefits have led to the rapid development of rubber and plastic insulation materials, and the detection of its performance has also been carried out. This paper combines Labthink's W3/0120 water vapor transmission rate tester to adopt a closed-cell elastic structure for rubber-plastic insulation pipe B1 flame-retardant rubber-plastic insulation pipe. It has soft bending resistance, cold resistance and heat resistance. It also has excellent performance at the same time with sacrificial damping.
