The method of judging the quality of tarpaulin by observation

In the past, most manufacturers did not have strict testing specifications for tarpaulin products, and they have always ignored this problem. Therefore, users are gradually guided to a wrong way to judge the quality of the tarpaulin, such as judging the wear resistance and folding resistance of the PVC coating by the feel and appearance; perhaps by simply testing the thickness and weight to judge the quality of the tarpaulin; or by manual tearing Determine whether the pull of the tarpaulin is good or not. In fact, these are all wrong methods, which are very unscientific. The strength of the first ancestors cannot be determined. This requires professional equipment to obtain accurate data from the same standard test in the same environment; many people think that the tarpaulin is heavy enough. Thick, then the production materials are better and more wear-resistant, which is also a more one-sided understanding. Then, after testing various tarpaulins in the market by the tarpaulin testing center and using professional equipment to test the color fastness, aging, tensile load, tear load, abrasion resistance and folding resistance of the tarpaulins, the results are checked. After the summary and analysis, a set of methods for judging the quality of tarpaulins through appearance and appearance have been summarized. 1. The smell of the tarpaulin: there is a pungent smell, the coating material must be poor, not wear-resistant, and easy to age; 2. The surface texture of the tarpaulin: the cloth texture is blurred or unclear, the price is low, the coating material must be poor, and it is not resistant Grinding, easy to age; 3. Tensile load of tarpaulin: the size needs to be tested by professional tensile testing equipment; 4. Tear load of tarpaulin: the size needs to be tested by professional tensile testing equipment; manual tearing and observation of the tear opening can only determine the coating material Good or bad, the tear is uneven, the surrounding folds are fierce, and the yarn (except industrial yarn) is intertwined, indicating that the adhesion between the coating and the yarn is poor, and the coating material must be poor, not wear-resistant, and easy to age. Five, tarpaulin wear resistance; color fastness; folding resistance; aging requires professional equipment testing or time verification.
