目前的建筑大多以鋼材構成，并且建筑越來越密集，一旦發生火災，一時難以撲滅。業內人士指出鋼結構(工程結構)的構件中要屬鋼柱占。立柱是整個輕鋼結構建筑的主要承壓構件，在火災中由于長時間的高溫，會產生局部（part)屈曲、整體屈曲和截面屈服，這就需要涂刷鋼結構防火涂料。

At present, most of the buildings are made of steel, and the buildings are more and more dense. Once there is a fire, it is difficult to extinguish it. Industry insiders pointed out that the steel structure (engineering structure) components should be steel column. The column is the main pressure bearing component of the whole light steel structure building. Due to the long-time high temperature in the fire, it will produce partial buckling, overall buckling and section yield, which requires the steel structure fireproof coating.

防火涂料立柱是鋼結構(工程結構)中的首要承重構件，防火涂料涂刷立柱就會增加鋼結構的耐火極限，在抗火設計中首先要保證鋼柱的安全，防火涂料在鋼柱的應用又是很廣泛(extensive)的，所以，施工團隊在施工的時候一定要注意鋼柱的重要性，在購買鋼柱防火涂料時一定要選擇正規的防火涂料生產(Produce)廠家，購買，確保鋼結構鋼柱部件的安全。

Fire retardant coating column is the primary load-bearing component in steel structure (engineering structure). Painting the column with fire-retardant coating will increase the fire-resistant limit of steel structure. In fire-resistant design, the safety of steel column should be ensured first. The application of fire-retardant coating in steel column is extensive. Therefore, the construction team must pay attention to the importance of steel column during construction and purchase fire-retardant coating for steel column When you must choose the formal fire retardant coating manufacturer, purchase, to ensure the safety of steel column components of steel structure.

一、鋼結構(工程結構)工程防火涂料的種類選擇

1、 Type selection of fire retardant coating for steel structure (engineering structure)

就以省棗莊市為例，每年涉及(to involve)到鋼結構(工程結構)的建設工程約有一百余個；發現在實際工程中鋼結構(工程結構)防火涂料的正確選用上存在一些問題，常常有一些混淆亂用現象，筆者分析(Analyse)認為其中大致有以下三種情況：

Taking Zaozhuang City as an example, there are more than 100 construction projects involving steel structure (engineering structure) every year. It is found that there are some problems in the correct selection of fire retardant coating for steel structure (engineering structure) in practical projects, and there are often some confusion and misuse. The author analyzes and thinks that there are three situations as follows:

一是把室內鋼結構(工程結構)防火涂料與室外鋼結構防火涂料相混淆。室外使用環境要比室內嚴酷得多，涂料在室外要經受日曬雨淋，風吹冰凍，應該選用耐水、耐凍融、耐老化、強度（strength)高的防火涂料。但在實際巡查中，發現有些工程的室外鋼結構防火保護使用了僅適用于室內的防火涂料。

One is to confuse the fire retardant coating of indoor steel structure (engineering structure) with that of outdoor steel structure. The outdoor use environment is much harsher than the indoor environment. The coating should be exposed to the sun, rain, wind and freezing. The fire retardant coating with water resistance, freeze-thaw resistance, aging resistance and high strength should be selected. However, in the actual inspection, it is found that the fire-proof coating only suitable for indoor is used in some projects.

二是耐火極限要求大于1.5h的承重鋼結構(工程結構)不能選用正確的鋼結構防火涂料。有些設計人員錯誤地認為，防火涂料的耐火時間與涂料的厚度成正比，只要增加防火涂料的厚度就可以相應提高涂料的耐火時間，從而錯誤地把一些超薄型涂料用于耐火極限要求大于1.5h的承重鋼結構。

The second is that the correct fire retardant coating cannot be selected for load-bearing steel structure (engineering structure) whose fire resistance limit is greater than 1.5h. Some designers mistakenly believe that the fire resistance time of the fire retardant coating is directly proportional to the thickness of the coating. As long as the thickness of the fire retardant coating is increased, the fire resistance time of the coating can be increased accordingly. Therefore, some ultra-thin coatings are wrongly applied to the load-bearing steel structure whose fire resistance limit is greater than 1.5h.
