随着改革开放的不断深入和社会经济的迅速发展,城市建设日新月异,一些大跨度和超高层建筑物应运而生。为了满足建筑物跨度大和高度高的要求,钢结构应用越来越广泛。钢结构耐火极限低这一缺陷大大制约了钢结构的发展,为了满足钢结构的应用需求,一些新兴的防火涂料随之诞生。 With the continuous deepening of reform and opening up and the rapid development of the social economy, urban construction is changing with each passing day, and some large-span and high-rise buildings have emerged. In order to meet the requirements of building spans and heights, steel structures are increasingly used. The low limit of fire resistance of steel structures greatly restricts the development of steel structures. In order to meet the application requirements of steel structures, some new fire-retardant coatings are born.
