1.钢:活动板房一般选用一些耐腐蚀钢,这种耐腐蚀钢一般称为耐候钢;耐候钢中含有磷、铜、镍、铬、钛等金属,这些材料对钢表面会形成很高的防护效果,从而提高钢的耐蚀性;活动板房直接面对阳光、雨水、霜冻和降雪的自然气候,耐候钢的低温冲击韧性也优于普通结构钢。
1. Steel: generally, some corrosion-resistant steel is selected for prefabricated house, which is generally called weathering steel; the weathering steel contains phosphorus, copper, nickel, chromium, titanium and other metals, which will form a high protective effect on the steel surface, so as to improve the corrosion resistance of the steel; the movable plank house is directly facing the natural climate of sunlight, rain, frost and snow, and the low-temperature impact toughness of the weathering steel is also It is superior to ordinary structural steel.

2.高温锌:热浸锌是一种耐高温产品;其制作工艺达到600度高温浸泡。钢构件表面有这样一层锌层,而且锌层的厚度已经达到了5微米,而且附着在钢构件表面的锌层也有详细规定,薄板不得小于65微米,厚板不得小于86微米。从而耐高温,耐腐蚀。这种工艺的优点是高温不易变化,周期长,质量有保证。因此,本产品广泛应用于户外大型钢结构,然后清洗;对于钢结构的设计,我们应避免设计有粘结面的构件,以避免粘结面缝隙中酸洗不彻底或酸洗;导致镀锌表面出现黄水。热浸锌是在高温下进行的。
2. High temperature zinc: hot dip galvanizing is a kind of high temperature resistant product; its production process reaches 600 ℃ high temperature immersion. There is such a layer of zinc layer on the surface of steel member, and the thickness of zinc layer has reached 5 μ m, and the zinc layer attached to the surface of steel member is also specified in detail. The thin plate shall not be less than 65 μ m, and the thick plate shall not be less than 86 μ M. Therefore, it is resistant to high temperature and corrosion. The advantages of this process are that the high temperature is not easy to change, the cycle is long and the quality is guaranteed. Therefore, this product is widely used in outdoor large-scale steel structure, and then cleaning; for the design of steel structure, we should avoid the design of components with bonding surface, so as to avoid incomplete pickling or pickling in the gap of bonding surface, resulting in yellow water on galvanized surface. Hot dip galvanizing is carried out at high temperature.
3.涂层方法:涂层的耐蚀性一般不如高温锌,所以室外钢结构多用在室内钢结构或相对容易维护。这种涂料的特点是成本低,更多地用于室内钢结构。这种涂料防锈,不需要耐高温,也不需要直面大自然的气候。涂装法施工的步是除锈,涂装比高温锌除锈要求更高,所以要求高的涂装一般采用喷砂喷丸去除全部铁锈和油污。野外施工的涂料可以手工除锈。涂层对环境要求更高。涂料施工环境要少扬尘,构件表面不能有灰尘,涂装后四小时内不能下雨。不同的涂层对不同的腐蚀条件有不同的抵抗能力。
3. Coating method: the corrosion resistance of coating is generally not as good as that of high temperature zinc, so outdoor steel structure is mostly used in indoor steel structure or relatively easy to maintain. This kind of coating is characterized by low cost and is more used in indoor steel structure. This kind of coating is rust proof and does not need to be resistant to high temperature and natural climate. The first step of coating method is rust removal, which requires more than high temperature zinc rust removal. Therefore, sandblasting and shot peening are generally used to remove all rust and oil stains. The paint applied in the field can be derusted by hand. The coating has higher environmental requirements. There should be less dust in the coating construction environment, there should be no dust on the surface of the components, and there should be no rain within four hours after coating. Different coatings have different resistance to different corrosion conditions.
4.热喷涂铝(锌)复合涂层:该涂层的优点是对构件尺寸具有较强的适应性,几乎可以制成零件的形状和尺寸。另一个优点是,该涂层的高温是局部的,因此不会因高温而发生变化。
4. Thermal spraying aluminum (zinc) composite coating: the advantage of the coating is that it has strong adaptability to the size of components, and can almost be made into the shape and size of parts. Another advantage is that the high temperature of the coating is local, so it will not change due to high temperature.
与此相结合,钢结构活动板房的耐蚀性越来越强,现代工艺处理也越来越完善。活动板房的主要结构是钢,活动板房的质量取决于钢的质量和涂层的质量。
Combined with this, the corrosion resistance of steel structure movable plank house is more and more strong, and the modern process treatment is also more and more perfect. The main structure of prefabricated house is steel. The quality of prefabricated house depends on the quality of steel and coating.
