Insulation board and holding plastic from the chemical reaction? Insulation board dip in the glass, with the structure of plastic line
, to "plastic" approach in the pipe machine by extrusion processing Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, easy construction and other characteristics, in the construction project has been more and more widely used
Both are made of polystyrene as the basic raw material for processing, but due to the different processing technology, the formation of two different insulation materials
Foam cement, the formation of a certain tension of the foam, and then the foam and cement slurry at the same time mixing, mixing process will continue to expand the cement, when the expansion effect to a pre-set ratio can be formed after the foam cement. Foaming is divided into physical and chemical methods of two kinds of foam, which is the physical method of foaming foam is the use of air compressor (that is, foaming machine) to form a bubble with a certain tension, and then foam and cement At the same time mixing, mixing process will continue to expand the cement, when the expansion effect to a pre-set ratio can be formed after the foam cement. Chemical foam, but refers to the blowing agent (liquid / powder solid) added to the cement slurry for mixing, the chemical reaction to release the gas so that the cement volume continues to expand, the expansion effect to the pre-formula set the state to form foam cement The Polystyrene foam board - also known as foam board, EPS board is made of volatile liquid blowing agent containing polystyrene beads, heated by the preheating in the mold after heating the formation of white objects, its fine The structural characteristics of obturator
