The choice of temperature and humidity test chamber insulation material

Electric appliances used or used in everyday life or work, as long as they involve temperature control, need to be insulated. Then, the choice of the thickness and material of the constant temperature and humidity test chamber insulation material is very important. The following is the discussion of the choice of the material of the insulation material by the ASITECH Technical Department.

The choice of heat preservation method differs from the sensing method and adopts corresponding methods and materials. For example, a vacuum insulation layer is used in order to eliminate hot air minute heat transfer. However, due to technical and cost reasons, the current environmental testing equipment uses insulation materials such as ultra-fine glass fiber cotton (abbreviated asbestos), polyurethane rigid foam, and foamed styrene. Now we analyze and analyze these materials. The difference.

Asbestos, due to its good thermal insulation properties and low cost, was first applied on a large-scale thermal insulation layer of thermal insulation materials. It also has the characteristics of easy operation and filling, so it is widely used in thermal conduction and thermal insulation. However, its big problem is that glass fiber is easily inhaled into the lungs of human body, and it easily penetrates into clothing and touches the skin, and then penetrates into the human body. Into the lungs and the body of the glass fiber can not be digested and discharged, and glass fiber is prone to cancer. Therefore, in recent years, many industries have banned the use of asbestos as a thermal insulation material.

Polyurethane rigid foaming is also widely used, but because the temperature range of polyurethane rigid foam insulation cannot be higher than 100°C, it limits its scope of use. We have a dynamic and highly qualified sales force and technology. A comprehensive and experienced after-sales service team is not only the source of our company's development, but also the guarantee that we provide our customers with good services. The customer's full trust and support for the company is the foundation on which we rely to develop. To meet the different needs of users to a large extent is our goal.
