1、 从外观标识上看：一级彩涂板正品产品均为立式木栈板精包装，而协议产品多为卧式包装。
2、 从彩钢板的面漆和后涂层识别：高档彩钢板的漆膜厚度较厚，外观较重，颜色纯正，后涂层较厚。
3、 产品质量证明书：供方提供的产品质量证明书中“标准”、“卷号/捆号”、“炉号”、“合同号”、“重量”五个参数与相应的“标准”、“捆号”、“炉号”、“用户合同号”、“净重”完全一致，如果相差很小，误差应该非常大，如果复合砝码称重有误差，复合砝码可以做成两卷，其差值应该相等。
彩钢板外观用肉眼检查，彩钢板尺寸和外观用适当的量具测量，取样时每批取一块钢板，头尾切一根钢卷。彩涂板应分批检验。每批由同一牌号、规格、基材类型、涂层重量、涂层厚度、涂层类型、颜色不大于25吨的彩涂板组成。彩涂板复验应符合GB/t17505的规定。
彩涂辊俗称聚偏氟乙烯彩涂辊。它在建筑中有很好的应用。其主要优点是具有良好的抗紫外线能力。彩涂辊采用高档聚偏氟乙烯树脂制成。众所周知，PVDF的化学键和化学键之间存在着很强的键能，使其具有很好的耐腐蚀性和保色性，是建筑用彩涂钢板涂料中最先进的产品，其分子量大且呈直键结构。除耐化学性外，其机械性能、抗紫外线和耐热性也得到了广泛的认可。
我相信当你购买任何产品时，你应该注意产品的质量。至于彩涂辊的质量，我不知道你们是否研究过或注意过。当我们选择的时候，我们可能会关注不同的点，所以彩涂辊的质量也是不同的。影响彩涂辊质量的因素有哪些？以下是为您整理的相关资料。希望你不要错过。
彩涂辊的影响因素很多，其中质量主要受物理化学性能和表面质量的影响，对各种缺陷的认识也不尽相同，但一般可分为基材质量差、涂层表面张力变化、预处理不当等，固化缺陷、涂层缺陷和划痕。另外，我们都知道彩涂辊的生产过程是连续的。一旦出现质量缺陷，就要与全线密切配合，找出缺陷产生的原因并加以解决。因此，可以说，正确选择生产工艺和产品的生产工艺对产品的质量也非常重要。

1、 From the appearance identification: the first-class color coated plate genuine products are all vertical wooden pallet fine packaging, and the agreement products are mostly horizontal packaging.

2、 Identification from the top coat and back coat of color steel plate: the film thickness of top-grade color coated plate is relatively thick, the appearance is heavy, the color is pure, and the back coat is thick.
3、 Product quality certificate: the five parameters of "standard", "coil No. / bundle No.", "heat No.", "Contract No.", "weight" in the product quality certificate provided by the supplier are completely consistent with the corresponding "standard", "bundle No.", "heat No.", "user Contract No.", "net weight" in the label on the coil, and the error should be extremely high If there is a small difference, if there is an error in the weighing of the compound weight, the compound weight can be made into two rolls, and their difference should be equal.
The appearance of color coated plate shall be inspected by naked eyes; the size and appearance of color coated plate shall be measured by appropriate measuring tools; when sampling, one piece of steel plate shall be taken from each batch, and one piece of steel coil shall be cut at the head or tail. Color coated plates shall be inspected in batches. Each batch shall be composed of color coated plates with the same brand, specification, substrate type, coating weight, coating thickness, coating type and color not more than 25 tons. The re inspection of color coated plate shall comply with the provisions of GB / t17505.
Color coating roll is commonly known as polyvinylidene fluoride color coating roll. It has a good application in architecture. The main advantage is that it has a good anti ultraviolet ability. Color coating roll is made of high-end polyvinylidene fluoride resin. We all know that there is a strong bond energy between chemical bond and chemical bond of PVDF, which makes the coating very good Its corrosion resistance and color retention make it the most advanced product in the color coated steel plate coating used in the construction industry, and its molecular weight is large and straight bond structure. In addition to chemical resistance, its mechanical properties, UV resistance and heat resistance are also well recognized.
I believe that when you buy any product, you should pay attention to the quality of the product. As for the quality of the color coated roll, I don't know if you have studied or paid attention to it. When we choose, we may focus on different points, so the quality of the color coated roll is also different. What are the factors that affect the quality of the color coated roll? The following is the relevant information compiled for you. I hope you don't miss it.
There are many influencing factors for the color coating roll, among which the quality is mainly affected by the physical and chemical properties and surface quality, and the understanding of various defects is also different, but generally can be divided into poor substrate quality, change of coating surface tension, improper pre-treatment, curing defects, coating defects and scratches. In addition, we all know that the production process of color coating roll is continuous. Once there are quality defects, we need to work closely with the whole line to find out the causes of the defects and solve them. Therefore, it can be said that the correct selection of the production process and the production process of the product is also very important for the quality of the product.
