Question:

Extrusion insulation board b1 and b2 grade fire resistance how to distinguish?

How is the flame and combustible defined by the naked eye? I burn the B1 level and B2 level XPS board is different? Question added: detection time is longer, can quickly and intuitively identified? More

Answer:

Air-conditioned room can not have flammable gas, in order to avoid explosion and fire do not frequent switch air conditioner, because the compressor starts when the current is running a lot of times the current, easy to burn the compressor motor 3) Do not put things on the outdoor unit of the air conditioner to avoid air conditioning noise. It is a great persecution for the air conditioner. The temperature of the general air conditioner is adjusted to 26 ° C to 28 ° C. , To avoid excessive power consumption next to the air conditioner must not be twitching Fengqi gong bite astringent ax to have a high temperature heat source, so as not to heat the panel deformation
Mainly for insulation to reduce heat loss. So use a good insulation material insulation. Hope it helps you.
Panasonic refrigerator with the world's leading vacuum insulation material Vacuuminsulationpanel (referred to as VIP) vacuum insulation board, is developed in recent years, a new type of highly efficient insulation material, which uses vacuum insulation principle, under vacuum conditions, the thermal conductivity is very low , Widely used in household appliances. The product to fill the gaps, is a leading international high-tech products. . VIP in the production and application process does not use ODS substances. . the insulation layer of the same thickness, you can save energy. . the same energy consumption, VIP can reduce the thickness of the insulation layer to reduce the volume of objects, increase storage space. . VIP design engineers can provide a variety of flexible options. . CFC consumption of ozone, destruction of the ecological environment, if the alternative blowing agent, its high thermal conductivity, reducing the thermal insulation properties of the foam, although the environmental protection, but need to consume more energy, and VIP is environmentally friendly And the dual advantages of energy saving. . VIP on environmental protection and national energy conservation has a great contribution. . VIP thermal conductivity is PU one-eighth, is the replacement of insulation materials. Vacuum insulation panel (VIP) technology industry has quickly formed a practical industry trends, and industry-class enterprises to adopt. Was rated as energy-saving refrigerator model products which is the use of VIP technology to achieve energy-saving purposes. (BCD-239DVC), Panasonic "energy saving king" refrigerator (NR-E461U), the new energy-saving "Golden Eagle" refrigerator (BCD-218E) Meiling "digital energy-saving Wang" refrigerator (BCD-239DVC) BCD-200A / HC, BCD-270A / HC and other six models (BCD-219U / C), the best energy-saving refrigerators, including BCD-180A / HC, BCD-200A / HC, BCD-270A / HC and other six models Wait.
