Introduction:
Basically, the use of traditional pipes with temperature performance requires insulation, and the selection of insulation materials naturally becomes a key step. The products on the market are mixed, the value is difficult to judge, how to avoid the phenomenon of pipeline condensation, corrosion and rust? Is there any insulation material that can let us "once and for all"?
What is dew?

Before talking about the phenomenon of "dew", we must first understand what the phenomenon of dew is. Condensation means that when the water vapor in the air reaches saturation, if the ambient temperature continues to drop, the phenomenon of precipitation of supersaturated water vapor in the air begins. Condensation occurs in many places, such as building walls, air conditioning equipment and so on.
Common dew formation scenes and phenomena in our daily life include basements, where the indoor air temperature is greatly affected by the environment. In the low-temperature and high-humidity environment during the plum rain season from May to September, the temperature and humidity can easily reach the dew point, resulting in dew formation.
In addition, when the temperature of the water flowing in the pipe is much lower than the ambient temperature (such as room temperature), condensation may also occur. Water droplets formed by condensation adhere to external surfaces such as pipes or walls in the environment, which may have a bad effect on equipment or other work; Such as pipe rust, reduce the insulation function of the pipe equipment itself.
Second, what insulation materials are generally used to prevent condensation?
How to prevent and prevent the occurrence of dew hazard? The research shows that when the inner surface of the external wall of the building is selected, the outer envelope with small heat transfer coefficient and high thickness can make its inner surface temperature not too low to ensure that its surface does not produce condensate. For condensation phenomenon, people often use thermal insulation materials to achieve thermal insulation, waterproof and anti-seepage, anti-condensation effect.

Rubber and plastic is a kind of closed cell foam structure insulation material, all the bubble holes are independent of each other, do not connect the bubble to form a closed air layer, effectively improve the product's thermal insulation performance and waterproof penetration ability, so as to ensure the long-term effective and stable performance of the product. Therefore, building insulation will choose rubber and plastic insulation materials as external wall filling materials to prevent the occurrence of dew phenomenon hazards.
Generally speaking, B1 grade rubber and plastic is a more commonly used insulation material in the problem of anti-condensation. At present, some rubber and plastic products do not have the effect of curing the problem of condensation, and there is still a phenomenon of condensation; It may be that the quality of rubber and plastic products does not meet the relevant standards or requirements.

In fact, the traditional pipe that needs insulation, whether it is foam glass or aluminum silicate or glass wool, belongs to the open-hole material, which is directly covered on the pipe, and the material is found to rust the pipe after long-term use; Secondly, water absorption will occur after the application of thermal insulation cotton for a long time, thereby reducing the thermal insulation effect of thermal insulation materials; Spraying a thin layer of aerogel coating on the pipe can greatly reduce the possibility of condensation and reduce the construction time.
In dealing with the problem of anti-condensation, traditional thermal insulation materials naturally occupy most people's cognition, and are generally recognized under long-term use. When the industry develops, we should also follow the footsteps of the industry, try to think about the problem from a different Angle, and find, accept and recognize the advantages and applications of new materials in the present. The "composite process" is a good example.
