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
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

It is a white solid with a fine closed-cell structure which is heated and preformed in a mold by heating before it is made of a volatile liquid blowing agent.
Sound insulation and polystyrene insulation board which sound insulation better?
But its assembly is more complex and is not conducive to high-level construction, safety performance Dingzao cut to cut the salt tax is also poor, if the assembly is very easy to accident, and susceptible to natural factors and reduce its safety, As more and more emphasis on the protection of green today, it is bound to be replaced by steel scaffolding fastener type steel scaffolding with easy processing, easy handling, versatility and other advantages, is currently the largest use of China, the most common use of a scaffolding, but this scaffolding security is equally poor, the construction efficiency Low, scaffolding maximum erection height of 33 meters, can not meet the development needs of high-rise building construction bowl button assembly disassembly is relatively simple, the assembly performance is also good, more in the United States, China seems to use is not very wide But personally think that the future bowl button scaffolding will certainly be popular, there are prospects aluminum scaffolding is mainly lightweight, corrosion-resistant But not a high degree of construction, can not be high-level construction the disc does not seem to use the fastener with the bowl button type, universal joint do not understand So, personally think that in China fastening scaffolding or the mainstream, bowl button-style prospects are good
