It has a low thermal conductivity, low density, high flexibility, fire insulation lining on water and other characteristics. Light weight, general 10-96kg / m3, Weifang insulation board, 20kg / m3 or less for the carpet, 24-48kg / m3 as the hard board, insulation board, 48-96kg / m3 for the hard plate, wherein 48kg / m3 can be ceiling , a softening point of about 500 ° C, insulation 300 ° C, a large amount of the United States, k = 0.9. Calcium silicate insulation products, the successful development of the country 70 years, with high compressive strength, thermal conductivity, easy construction, can be used repeatedly characteristics, is widely used in the power system. XPS and sheet metal bonding, XPS extruded plate bonding cement wall: ※ can PU-50 two-component special adhesive, the adhesive is divided into A, B groups, the ratio of 5: 1, when used according to the quality of parts After mixing with a serrated blade sizing, either directly after cold load. ※ If you need to improve tack, insulation board classification, such as interior and exterior bonding, insulation board price may be further coated plastic sheet XPS sizing, sizing extruded plate after airing for some time, let it appear stretched silk and has a certain viscosity recombination, so to avoid sagging or sticky adhesive move. XPS is a bit special adhesive: water, cold, acid, there is a certain toughness can be adapted to the hot summer and cold winter climate change.
