为了防止火灾给钢结构建筑造成灾难性破坏，确保人员、财产的安全，因此建筑标准规定用耐火涂层保护钢结构。
In steel-frame buildings, steel members should be protected by spraying fire-resistant coating so as to preventing from calamity of fire, insuring safety of life and wealth.
研究了涂料层中不同耐火粉料及粘结剂等因素对涂层强度的影响。
Some factors affecting coating strength, such as refractory and binder, were studied.
由该涂料制得的涂层遇火发泡膨胀，形成具有一定厚度的密实微孔状阻燃层，从而提高了钢结构的耐火极限。
The coatings film will be dilatated when contacted to fire, forming a high dense and micro-porous fire proofing layer to prolong the fire retardant limit of steel structures.
耐火钢提高了钢的高温强度，从而减少了防火涂层。
Newly developed fire resistant steels improve their elevated-temperature strength, thus reducing fire-resistant coating.
如按iso 834曲线升温，耐火性能达到3h，一般涂料涂层厚度约需20 ~30mm；由于涂层较厚，需要多次喷涂，施工困难。
E. g. by ISO 834 curve thawing, fireproof performance reach 3h, general coating thickness need about 20 ~ 30 mm, Due to the coating thicker, requiring multiple coating, construction difficulties.
