As a consumer, no matter what is unqualified, it always makes us feel disgusted. This is also the case in the PC endurance board market. In fact, unqualified PC endurance boards will have some similar features, and these functions can also be used as the basis for future identification. The following is a brief introduction of the main features of unqualified PC endurance boards by the Shanghai Jienai endurance board manufacturer:
1、 It is obvious that there is no trademark on the unqualified product brand, nor the production address and contact information of the endurance board manufacturer. If such a PC endurance board is rolled into a cylinder, it will be found that the PC endurance board will not recover after a period of time, thus judging that the recycled PVC content in the PC endurance board is relatively high.
2、 From the surface, the PC endurance board surface is quite vague, even with small spots, indicating that it is an unqualified product produced by industrial waste; PC endurance board is bent laterally. If it is easy to break, it is unqualified; After the PC Endurance Board is installed, if the PC Endurance Board looks dark and not bright, or stripes of different colors appear on the same PC Endurance Board, it means it is a poor product.
