1.钢结构防火涂料

钢材是一种不会燃烧的建筑材料,它具有抗震,抗弯等特性。在实际应用中,钢材既可以相对增加建筑物的荷载能力,也可以满足建筑设计美感造型的需要;还避免了混凝土等建筑材料不能弯曲,拉伸的缺陷。因此钢材受到了建筑行业的青睐,单层,多层,摩天大楼,厂房,库房,候车室,候机厅等采用钢材都很普遍。但是,钢材作为建筑材料在防火方面又存在一些难以避免的缺陷,它的机械性能,如屈服点,抗拉及弹性模量等均会因温度的升高而急剧下降。钢结构通常在450~650℃温度中就会失去承载能力、发生很大的形变、导致钢柱、钢梁弯曲,结果因过大的形变而不能继续使用,一般不加保护的钢结构的耐火极限为15分钟左右。因此,对钢结构进行保护势在必行。隧道防火涂料告诉您钢结构防火涂料刷涂或喷涂在钢结构表面,起防火隔热作用,防止钢材在火灾中迅速升温而降低强度,避免钢结构失去支撑能力而导致建筑物垮塌。从80年代初,我国也开始研制钢贵州防火涂料,至今已有许多优良品种广泛应用于各行各业。

厚涂型钢结构防火漆是指涂层厚度在8~50mm的涂料,这类防火涂料的耐火极限可达0.5~3h。贵州防火材料北京11选5告诉你在火灾中涂层不膨胀,依靠材料的不燃性、低导热性或涂层中材料的吸热性,延缓钢材的升温,保护钢件。这类钢结构防火涂料采用合适的粘结剂,再配以无机轻质材料、增强材料。与其他类型的钢结构防火涂料相比,除了具有水溶性防火涂料的一些优点之外,由于它从基料到大多数添加剂都是无机物,因此成本低廉。该类钢结构防火涂料施工一般采用喷涂,多应用在耐火极限要求2h以上的室内钢结构上。但这类产品由于涂层厚,外观装饰性相对较差。
