Who knows the fire endurance of rock wool color plate?
I'm glad to answer your question and offer you some of my experiences, for reference only. In fire?safety?rules, it can be divided into non-combustible component, hard-combustible component, combustible component according to the combustible degree of building materials. Rock wool board is building board recombinated artificially by fibers processed by coated steels and inorganic minerals like basalt mineral, because steel plate and rock wool which is the main components are non-combustible material, so rock wool board should be considered as non-combustible component. The fire endurance of rock wool board has its own judging criteria. Lose sustaining power, integrity and fire insulation function. Its fire endurance is within 2 hours.
I'm glad to answer your question and offer you some of my experiences, for reference only. rock wool board is artificial inorganic fiber taking basalt as raw material and produced by melting with high temperature, which has characteristics of lightweight, non-combustible, heat absorbing, small thermal conductivity. The initial research is a common type of application in the building mainly used for industrial buildings which should be consistent with provisions in "the application types and basic requirements of building insulation materials". Successfully tested in June, 1981 Rock wool board is a new type material with fuctions of thermal insulation, fire retardant, sound absorption. The fire endurance of general rock wool board is 140-180 degrees, within two hours, better not exceed this safe period, in order to avoid security risks.
Colored steel rock wool board is used for areas with high fireproofing requirements. Colored steel rock wool board belongs to class A according to "Fireproof? Specification of Building Interior Decoration?Design" whose lifetime can reach more than 15 years, operating temperature can up to about 700 ℃, maximum fireproofing time is 6 hours. And rock wool colored plate is environmentally friendly materials, which is is the preferred material in the construction industry .
