随着钢结构建筑的迅猛发展,对钢结构的保护也提到了重要的日程,我国目前普遍采用的是钢结构涂料保护法,也就是使用一种防火涂料涂敷在钢材上,一旦发生火灾起到应有的防火保护作用。但防火涂料在使用中也出现了一些问题。一是防火涂料型号选择错误。根据《钢结构防火涂料通用技术条件》把防火涂料按照涂层厚度分为三种,即厚型涂料、薄型涂料和超薄型涂料。从涂料的使用趋势看,薄型及超薄型涂料的使用越来越多,一方面是为了追求装修效果,另一方面为了降低工程造价。而生产厂家为了迎合这一趋势,不顾目前我国的实际原料生产水平及涂料生产工艺水平,盲目地“科学”组合配方,用近似只有实验条件下才能产生的“产品”推向市场,其隐患可想而知。二是没有充分考虑防火涂料的老化及耐久性。建筑工程提倡的是百年大计,一方面要合理选择并使用防火
With the rapid development of steel structure and building, the protection of steel structure also mentioned an important schedule. At present, steel structure coating protection law is widely used in our country, that is, a fire retardant coating is applied on the steel. Once a fire occurs To the due protection of fire. However, there are some problems in the use of fire retardant coatings. First, choose the wrong type of fire retardant paint. According to the “general technical conditions of fire-retardant steel structure,” the fire-retardant coatings in accordance with the thickness of the coating is divided into three types, namely, thick coatings, thin coatings and ultra-thin coatings. From the use of coatings trends, thin and ultra-thin coatings more and more use, on the one hand, the pursuit of decoration effect, on the other hand in order to reduce construction costs. In order to cater to this trend, the manufacturer, in spite of the current level of actual raw material production and the level of paint production technology in our country, has blindly “scientifically” combined the formulations and introduced “products” into the market with similar conditions only under experimental conditions. Think of it. Second, do not fully consider the aging and durability of fire retardant coatings. Construction projects advocate is a hundred years plan, on the one hand to choose and use fire prevention
