The standard for the use of HDP pre-painted sheet

Let’s talk about the use of HDP color-coated board standards As the use rate of HDP color-coated board is becoming more and more common, its quality is getting higher and higher, due to its characteristics and advantages, it is widely used, in order to let you use it better, let’s first understand what the use standard of HDP color-coated board is at this stage. 　　

China’s annual apparent consumption of HDP color-coated plate is less than 5 million tons, but at present, HDP color-coated plate professional skills (total output) more than 20 million tons, overall, the market sales rate of color-coated diesel generator sets is only 20%, although hot-dip aluminum-galvanized plate color-coated steel is China’s national industry standard, but this specification is only mandatory, not mandatory, however, the unified design standard of profiled steel plate for construction engineering is not perfect, with the help of a sense of responsibility in the field, most of them are empty talk at this stage. Like many decorative building materials of HDP color-coated plates, it is unrealistic for ordinary people to judge the quality and service life of raw materials with their professional ability and vision, without professional weapons and equipment, even technical professionals can not identify the quality, under the current professional ability standards, it is impossible to quickly identify the service life of color-coated steel plate and aluminum alloy plate, even if it is coated with a coating with excellent anti-ultraviolet performance, it takes 1000 hours to identify, which gives a lot of fake and shoddy products – color-coated steel plate, Aluminum alloy plates leave an opportunity to take advantage of, because the raw materials of counterfeit and shoddy products can last for 1-2 years before the project is completed. 　　

The above is the standard of use of HDP color-coated board at this stage, you can go to understand that in the process of use, you must follow the correct operation method in order to achieve good results. 　　

Methods to prevent the rust of color-coated steel plates In the production process of color-coated steel plates, although relevant anti-corrosion and anti-rust measures have been taken, if they are not used and stored properly, they may still rust and affect their service life, so how to effectively avoid this problem? 　　

1. The color-coated steel plate should be stored in a clean and tidy environment to avoid the corrosion of various corrosive media, and the ground of the yard should be flat, free of hard objects, and have sufficient bearing capacity. 　　

2. Some types of color-coated steel plates should be placed on rubber pads, skids, brackets and other devices, and the lock should be facing upwards, and cannot be directly placed on the ground or transported. 　　

3. In addition, it should be stored in a dry and ventilated indoor environment, avoiding outdoor storage and places prone to condensation and large temperature differences, and the storage location should also be reasonably arranged to facilitate access and reduce unnecessary movement. 　　

Painted steel plates come in various patterns and colors, and if they rust, it will not only directly affect their aesthetic use, but also affect the performance and service life of the product to varying degrees.
