Price and testing method for galvanized sprayed plastic barriers in factory area

声屏障的价格主要的影响因素有声屏障屏体材质的选择、屏体厚度、间距、高度等因素决定，而好的镀锌喷塑也能影响到声屏障价格的高低。

The main factors affecting the price of the sound barrier are the selection of the material of the sound barrier, the thickness, the distance and the height of the screen, and the good galvanizing spray can also affect the price of the sound barrier.

声屏障浸塑、镀锌、喷镀等防腐处理

Anticorrosion treatment of sound barrier, dip coating, galvanizing, spray plating and so on

如何影响着声屏障的价格选择？

How do you affect the price selection of the sound barrier?

一般塑粉等级分类，是按质保的年限来分类。

The general classification of plastic powder grades is classified according to the years of quality assurance.

质保3-5年的塑粉，每吨2.2万元左右；质保5-8年的塑粉，每吨2.6万元左右；质保8-10年的塑粉，每吨4万左右。

The plastic powder that is guaranteed for 3-5 years is about 22 thousand yuan per ton; the plastic powder that guarantees quality for 5-8 years is about 26 thousand yuan per ton; the plastic powder that guarantees quality for 8-10 years is about 40 thousand per ton.

回收的废旧塑料制品做的塑粉，每吨1.3万元左右；一年后开始退色、龟裂、脱皮、风化成粉末状。

The recycled plastic products are made of plastic powder, which is about 13 thousand yuan per ton. After a year, they are fading, cracking, peeling and weathering into powder.

我们公司（如客户无特殊要求）采用的是杜邦、阿克苏，质保5-8年不褪色不开裂的塑粉，并附有塑粉厂在国家建筑材料检测中心做的检测报告。

Our company (if the customer has no special requirements) is DuPont, Akesu, 5-8 years of quality assurance not faded plastic powder, and with a powder factory in the National Building Materials Testing Center for testing reports.

1，检测方法：用硬物在塑层表面做方格划痕试验和锤击试验。

1, the detection method: using hard objects to make scratch check and hammer test on the surface of plastic layer.

2，便宜的塑粉，紫外线照射后塑粉皮脆开裂，退色，塑性差，附着力不好，多雨和阳光充足地区极易老化，易腐蚀。这都是小厂料，常常在一年左右褪色。

2, cheap plastic powder, after ultraviolet radiation plastic powder brittle crack, decolor, poor plasticity, poor adhesion, rainy and sunny areas are very easy to age, easy to corrosion. These are small factories and often fade in about a year.

3，塑层镀锌层厚度也非常重要，H型钢立柱，如电镀锌，锌层厚度为5微米，上锌量10克/平方米；热镀锌，锌层厚度为60微米，上锌量450克/平方米。屏体的塑粉厚度为76微米以上。塑层是否均匀，塑层不均在迎阳光时呈现波浪花纹。

3, the thickness of the plastic layer galvanized layer is also very important, H steel column, such as galvanizing, zinc layer thickness of 5 microns, the amount of zinc 10 grams per square meter, hot galvanizing, zinc layer thickness of 60 microns, zinc content of 450 grams / square meters. The plastic powder thickness of the panel is more than 76 microns. Whether the plastic layer is uniform and the plastic layer is uneven is presented with wavy patterns when facing the sunlight.

无论是金属声屏障屏体以及边框还是非金属透明等屏体的边框、立柱等防腐处理，只有所有的金属表面要处理干净，塑层才能与金属牢固结合，防腐年限才有保障。

Whether it is the metal sound barrier screen body and the border or non metal transparent screen body of the border, column and other anticorrosion treatment, only all the metal surface to be treated clean, plastic layer can be firmly combined with metal, corrosion life is guaranteed.

1、屏体板材无论是镀锌板，还是铝合金板，都需要磷化，去除表面油污粉尘，表面都要处理，才能充分和塑层接触。（使塑层牢贴在金属上）

1, the panel plate, either galvanized or aluminum alloy plate, needs phosphating to remove the surface oil dust, and the surface should be treated to fully contact the plastic layer. (the plastic layer is firmly attached to the metal)

2、检测方法：看其塑层的附着力是否良好，用小刀划十字格方法或锤击方法检测，附着力对塑层的抗老化、抗紫外线、龟裂、脱皮等防腐特别重要。

2, detection method: see whether the adhesion of the plastic layer is good, use a knife to cross the cross method or hammer method detection, adhesion to the plastic layer of anti-aging, anti ultraviolet, crack, desquamation, and other anticorrosion of particular importance.
