Fire rating of external wall insulation board for gradually increase _ langfang three friends of insulation materials co. , LTD
now fire rating of external wall insulation board requirements gradually increase, the heat preservation effect and the first class A fire performance to achieve, rock wool for class A fire but high water absorption, easy bibulous failure, resulting in the heat preservation effect of modified fly ash and other inorganic insulation mortar has class A fire, but not easy to control, thermal conductivity and the production technology and construction conditions have very big concern, leading in domestic more number of exterior insulation materials should be foamed cement insulation board with good thermal insulation, thermal insulation, sound insulation, light load, such as performance, better than the other light solid plastic expanded perlite, ceramsite, asbestos products such as insulation materials. With the features of easy operation, high mechanization degree, vertical pipeline section, save work, mechanical, shorten the working hours, than the other way times working efficiency can be improved.
refers to the adoption of a certain fixed way (the heat preservation Bonding, mechanical anchoring, paste + mechanical anchoring, spraying, casting, etc. ) , the low thermal conductivity, Heat preservation and heat insulation effect is better) The thermal insulation materials and building the wall fixed one, increasing the average thermal resistance of the wall, so as to achieve insulation or heat insulation effect of a kind of engineering practice.
