EPS boards (also known as benzene board) is a polystyrene foam board for short. By polystyrene beads containing a volatile liquid blowing agent, upon heating advance thermoformed white solid having a fine closed cell structure in the mold. Is a raw material pre-made, curing, molding, drying and cutting the like. It can be made of different densities, different shapes of the foam article, and can produce a variety of different thicknesses of foam sheet. Widely used in construction, insulation, packaging, refrigeration, daily necessities, industrial casting and other fields. It can also be used to show venue, commodity cabinet, advertising signs and toy manufacturing. In order to meet the current national building energy requirements are mainly used in exterior wall insulation, external wall insulation, underfloor heating. Specifications: thermal conductivity w / mk ≤0.041 Apparent density kg / m3 15-32 Tensile strength Mpa ≥0.1 Compressive strength Dimensional stability% ≤0.3 Kpa ≥100 benzene board advantages: 1, has been operating into the system, the technology is mature. Because it has been used for nearly three decades in Europe and the United States, in the United States has built building up to 44 layers. Therefore, this technology has formed a system, an adhesive layer, insulating layer and facing layer supporting the use of more mature technical documents. 2, good insulation effect. 3, due to expanded polystyrene insulation materials, the price is not very expensive, so that the whole system is affordable. Easy for users to accept. 4, no complicated construction process, the general construction unit after a brief training, can grasp the essentials of construction, ease of technologies. Benzene board Disadvantages: 1, due to the nature of the plate itself, the intensity is not high, the low load-bearing capacity, the need for strengthening the process the outer wall tiles. 2, when plate factory over a period of maturity, to be placed some time before use. If the aging time is less, the quality of the sheet can not be guaranteed, lumber shrink after construction, the system is cracking. 3, no fire, a fire is burning, and will produce toxic gases.
