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
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.
