adj.耐火

The steel cylindrical casings using fire proof material,also heat insulating material interiorly, which forms fire-proof structure. 鋼板制成的圓筒外殼中使用了耐火材料，內(nèi)部也貼有絕熱材料，形成耐火結構。

The coatings film will be dilatated when contacted to fire, forming a high dense and microporous fire proofing layer to prolong the fire retardant limit of steel structures. 由該涂料制得的涂層遇火發(fā)泡膨脹，形成具有一定厚度的密實微孔狀阻燃層，從而提高了鋼結構的耐火極限。
