Application characteristics of rubber and plastic insulation materials in building insulation - low thermal conductivity: "Rubber sponge" has a low thermal conductivity, and the average temperature is 0.034w/mk at 0 °C. Therefore, under the same environmental conditions, the “rubber sponge†is thinner than the other insulation materials in order to achieve the same thermal insulation effect, thus saving space above the floor ceiling, especially for raising the height of the indoor ceiling. helpful.
“Rubber sponge†has strong resistance to water vapor penetration, its thermal conductivity can be stable for a long time, so the material has a long service life and low daily maintenance costs.
Good flame retardant properties This material contains a large number of flame retardant and smoke-reducing raw materials. The concentration of smoke generated during combustion is extremely low, and it does not melt in the fire, and does not drop the fireball. The material has self-extinguishing characteristics. According to GB8624-1997 "Classification Method of Combustion Performance of Building Materials", this product is B1 grade flame retardant material, ensuring safety and reliability.
Closed bubble structure, large "wet plastic sponge" is a closed-bubble structure with strong resistance to water vapor permeability. The wet resistance factor μ is greater than or equal to 3000, which constitutes a "built-in" waterproof vapor layer in the outside air. The water vapor is difficult to penetrate into the material, and the outer surface of the cold insulation layer does not have to be added with a vapor barrier. The "rubber sponge" as a whole is both an insulation layer and a moisture barrier layer.
The performance of rubber and plastic insulation materials is completely independent of the rubber foam insulation material, with closed bubble structure, so it has very low water vapor permeability; and integrates three functions of heat insulation, moisture proof and fire prevention, and the performance is stable. It is currently the ideal insulation material. The glass wool fiber has an open-cell structure with pores inside and connected to each other, and the water vapor permeability is extremely high; and if any protective layer is damaged, the heat insulation layer may be damaged, and the heat insulation effect is greatly reduced. Polyethylene (PEF) has a perforated structure inside, and the water vapor is also easy to penetrate. The material itself cannot be protected from moisture. Asphalt or other auxiliary materials are required as the moisture barrier layer. In addition, the texture itself is hard, the installation is complicated and the outer layer is easily damaged. , short life. Easy and fast installation method 
It has the advantages of a peristaltic pump, and a single tube is used alone
without cross-contamination; a wide flow range, reversible forward and reverse operation.Replaceable
charging power, light and portable, flexible operation, can easily cope with stratified sampling, deep water
sampling, sampling of gas samples, high-viscosity liquids, suspended liquid containing tiny particles, etc. It is
especially suitable for field operations.
