来源:http://www.jnqkgjg.com 日期:2019-02-26 发布人:admin

彩钢瓦又叫彩色压型瓦,具有质轻、色泽丰厚、高强、施工方便快捷、抗震、防火、防雨、寿命长、免保护等特色,是一种常用的修建材料。如今已被广泛推广应用,适用于工业与民用修建、库房、特种修建、大跨度钢结构房屋的屋面、墙面以及内外墙装修等。

Colored steel tile, also known as color pressed tile, has the characteristics of light weight, rich color, high strength, convenient and fast construction, earthquake resistance, fire prevention, rain proof, long life and no protection, and is a commonly used construction material. Now it has been widely used in industrial and civil construction, warehouse, special construction, roof, wall and interior and exterior wall decoration of long-span steel structure houses.
彩钢瓦在遭到风沙雨雪、烈阳霜露及一年四季的温度和湿度变化的作用下,都会使得彩钢瓦发生腐蚀的现象,那么该如何做好防护方法呢?彩钢瓦厂家为大家介绍下常用的方法:
Under the action of wind, sand, rain, snow, hot sun, frost and dew, and the change of temperature and humidity throughout the year, the color steel tile will be corroded. So how to do a good job of protection? Coloured steel tile manufacturers for you to introduce the following commonly used methods:
一、热喷铝(锌)复合涂层:这是一种与热浸锌防腐蚀作用适当的长效防腐蚀方法。具体做法是先对钢构件表面作喷砂除锈,使其表面暴露金属光泽并打毛。再用乙炔-氧焰将不断送出的铝(锌)丝融化,并用压缩空气吹附到钢构件表面,以构成蜂窝状的铝(锌)喷涂层(厚度约80μm~100μm)。
1. Thermally sprayed aluminium (zinc) composite coating: This is a long-term corrosion protection method suitable for hot-dipped zinc. The concrete method is to sandblast and rust the surface of steel components to expose the metallic luster and wool. Aluminum (zinc) wires are melted by acetylene-oxygen flame and then blown onto the surface of steel members with compressed air to form honeycomb-like Al (zinc) spraying coating (thickness is about 80-100 um).
然后用环氧树脂或氯丁橡胶漆等涂料填充毛细孔,以构成复合涂层。此法无法在管状构件的内壁施工,因而管状构件两端有必要做气密性关闭,以使内壁不会腐蚀。
Then, the capillaries are filled with epoxy resin or chloroprene rubber paint to form a composite coating. This method can not be applied to the inner wall of tubular members, so it is necessary to make the two ends of tubular members airtight so that the inner wall will not corrode.
二、涂层法:涂层法防腐蚀性一般不如长效防腐蚀方法(但当前氟碳涂料防腐蚀年限甚至可达50年)。所以用于室内钢结构或相对易于保护的室外钢结构较多。它一次成本低,但用于野外时保护成本较高。涂层法的施工的第一步是除锈。优异的涂层依赖于彻底的除锈。所以需求高的涂层一般多用喷砂喷丸除锈,暴露金属的光泽,除去一切的锈迹和油污。
2. Coating method: Coating method is generally not as effective as long-term anti-corrosion method (but the current anti-corrosion life of fluorocarbon coatings can even reach 50 years). Therefore, there are many outdoor steel structures which are used in indoor steel structures or are relatively easy to protect. It has low cost at one time, but higher protection cost when used in the field. The first step in coating construction is rust removal. Excellent coatings depend on thorough rust removal. Therefore, coatings with high demand usually use sand blasting to remove rust, expose the luster of metal, remove all rust and oil stains.
现场施工的涂层可用手艺除锈。涂层的选择要考虑周围的环境。不一样的涂层对不一样的腐蚀条件有不一样的耐受性。涂层一般有底漆(层)和面漆(层)之分。底漆含粉料多,基料少。成膜粗糙,与钢材粘附力强,与面漆结合性好。面漆则基料多,成膜有光泽,能保护底漆不受大气腐蚀,并能抗风化。不一样的涂料之间有相容与否的疑问,前后选用不一样涂料时要注意它们的相容性。涂层的施工要有适当的温度(5~38℃之间)和湿度(相对湿度不大于85%)。
The coating applied on site can be rusted by hand. The selection of coatings should take into account the surrounding environment. Different coatings have different resistance to different corrosion conditions. Coatings are generally divided into primer (layer) and topcoat (layer). Primer contains more powder and less base material. Coarse film formation, strong adhesion with steel, good adhesion with topcoat. Topcoat has many base materials and glossy film, which can protect primer from atmospheric corrosion and resist weathering. There is a question of compatibility between different coatings. When choosing different coatings, we should pay attention to their compatibility. The coating should be constructed at appropriate temperature (between 5 and 38 C) and humidity (relative humidity not more than 85%).
涂层的施工环境粉尘要少,构件表面不能有结露。涂装后4小时以内不得淋雨。涂层一般做4~5遍。干漆膜总厚度室外工程为150μm,室内工程为125μm,答应差错为25μm。在海滨或海上或是在有激烈腐蚀性的大气中,干漆膜总厚度可加厚为200~220μm。
The construction environment of the coating should be less dust, and the surface of the component should not be dew. No rain within 4 hours after painting. Coating is usually done 4 to 5 times. The total thickness of dry paint film is 150 micron for outdoor engineering and 125 micron for indoor engineering. The allowable error is 25 micron. The total thickness of dry paint film can be increased to 200-220 microns in the seashore or at sea or in the atmosphere with severe corrosiveness.
三、阴极保护法:在钢结构表面附加较生动的金属代替钢材的腐蚀。常用于水下或地下结构。
3. Cathodic Protection Method: Adding more vivid metal to the surface of steel structure instead of steel corrosion. Usually used in underwater or underground structures.
不少人对彩钢瓦有一个误区的认知,认为彩钢瓦的厚度是越厚越好,由于越厚就越耐用,但事实上并不是这样的哦,区分彩钢瓦的好坏不能只靠厚度与分量来衡量。现在许多的新型原料,厚度薄,原料轻,但刚好相反,耐用节能,性价比也是好的。所以有用鉴别其质量的好坏显得尤为重要。
Many people have a misunderstanding of the cognition of the steel tile, color steel tile thickness that is thicker better, because the more thick more durable, but in fact it is not bad Oh, distinguish color steel tile cannot be measured only by the thickness and weight. Now a lot of new materials, thin thickness, light material, but on the contrary, durable energy-saving, price is also good. So useful in differentiating its quality is particularly important.
