In the past, most manufacturers did not have strict testing standards for tarpaulin products, and they have been ignoring this issue. Therefore, the user is slowly guided to a wrong way to judge the quality of the tarp, such as judging the wear resistance and folding resistance of the PVC coating based on the feel and appearance; or judging the quality of the material through a simple test of the thickness and weight; or manually tearing it. Judge whether the tension of the tarp is good. In fact, these are all wrong methods and are very unscientific. First of all, the amount of human effort cannot be determined. This requires professional equipment to test the data in the same environment and the same standard to be accurate; there are still many people who think that the tarp is heavy enough Thick, then the production materials are better and more wear-resistant, which is a more one-sided understanding.
After the tarpaulin testing center used professional equipment to test the color fastness, aging, tensile load, tear load, abrasion resistance, and folding resistance of various tarpaulins on the market, the results were summarized. The analysis has now summed up a set of methods for simply judging the quality of tarpaulin and canvas through appearance and appearance.
1. Odor: There is a pungent smell, the coating material must be poor, not abrasion-resistant, and easy to age;
2. Surface texture: the cloth texture is fuzzy or unclear, the price is low, the coating material is definitely poor, not wear-resistant, and easy to age;
3. Tensile load: the size needs to be tested by professional tensile testing equipment;
Four, tearing load: the size needs to be tested by professional tensile testing equipment; manual tearing can only be used to observe the tearing point to judge the quality of the coating material, the tearing point is uneven, the surrounding folds are severe, and the length of the yarn (except industrial yarn) is exposed. First, it shows that the adhesion of the coating and the yarn is poor, and the coating material must be poor, not wear-resistant, and easy to age.
5. The abrasion resistance of the tarpaulin; color fastness; folding resistance; aging requires professional equipment testing or time verification.
