In the design, the building structure and the hydropower are generally designed by the Architectural Design Institute. The air conditioning ventilation is based on the design of the room. Or first air conditioning ventilation? More
Normal heat absorption is also due to poor ventilation (dirty) and air humidity so icing
Aluminum alloy metal shell better than the plastic shell; we all know that most of the market is now charging the lithium battery, lithium battery is the only drawback is the possibility of a long time with the explosion, so the use of aluminum Alloy shell, much better than steel; polymer battery is good, but the price is expensive,
Decoration refers to the home improvement part, housing construction is the content of the building
Polystyrene should not be polycyclic aromatic. Polycyclic aromatic groups generally refer to aromatic groups when multiple benzene rings are used. Not all of the hydrocarbon chemical products are carcinogenic, and our bodies are producing hydrocarbon compounds all the time. Polystyrene carcinogenicity is small. General benzene ring on the more substituents, the toxicity is relatively small, such as toluene is less than the toxicity of benzene. Of course, there are many compounds with benzene ring, so there are a lot of scholars to study with our body creatures do not meet the quality of raw materials to do the polymer, such as lactic acid production of polylactic acid, but the current Can be put into use much.
