In the past, most manufacturers did not have strict inspection standards for tarpaulin products, and they have always neglected this problem. Therefore, the user is gradually 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; perhaps through a simple test of the thickness and weight to judge the quality of the material; or manually torn Determine whether the tension of the tarp is good.
In fact, these are all wrong methods, which are very unscientific. The data obtained by professional equipment in the same environment and the same specification test is required to be accurate; there are many people who think that the tarpaulin is heavy and thick enough, then the production materials are better. More wear-resistant, that is a more one-sided understanding.
Then after Linyi Shengde Plastic Co.,Ltd used professional equipment to test the color fastness, aging, tensile load, tearing load, abrasion resistance, and folding resistance of various tarpaulins on the market, The results are summarized and analyzed, and now a set of methods to briefly judge the quality of tarpaulin and canvas through appearance and appearance have been summarized.
1. Odor: There is a flushing odor, the coating material must be poor, not abrasion-resistant, and easy to age.
2. Appearance texture: the texture of the cloth is fuzzy or unclear, the price is low, the coating material must be poor, not abrasion-resistant, and easy to age.
3. Tensile load: professional tensile testing equipment is required for testing.
4. Tearing load: professional tensile testing equipment is required; manual tearing investigation can only judge the quality of the tarpaulin coating material. The tearing hole is uneven, the surrounding folds are severe, and the yarn (except industrial silk) is exposed. Staggered canine teeth means that the adhesion of the coating and the yarn is poor, and the coating material must be poor, not abrasion-resistant, and easy to age.
