How to identify the advantages and disadvantages of Drywall Tape

High-quality Drywall Tape has three main indicators, namely alkali resistance, tensile strength, and cracking strain. Among them, the more important one is alkali resistance. Because in the case of poor alkali resistance, no matter how high the tensile strength is, the strength will decrease rapidly in the concrete and it will not be able to resist cracking.

As for the alkali resistance of Fiber Glass, Fiber Glass manufacturers mainly rely on the composition of the Fiber glass yarn and the alkali resistance of the coating glue. However, the quality of alkali-resistant Fiber Glass on the current market varies from good to bad, and the phenomenon of fake and shoddy products is worrying. There are many types of Fiber Glass products on the market with different prices. How to identify the quality is very important. To identify the quality, you must look, touch and pull.
Drywall Tape manufacturers mainly look at the positioning of the product. Positioning is the firmness of the grid. The stronger the grid, the better the positioning. If the grid is not strong and loose, it means the positioning is poor. Generally, the positioning of emulsion Fiber Glass is better than that of urine gel Fiber Glass. The cloth is positioned well.
The main thing to touch is to touch the surface of the product to see if it is prickly. If it is very prickly, it means that the product is coated with urine glue or earthen pot Drywall Tape. If there is no prickly feeling and it is very soft to the touch, it means that the product is of high quality. Very good. Generally, emulsion Fiber Glass has a better feel.
Pulling is mainly to test the tensile strength of the product. Although it cannot detect the tensile strength after soaking in alkaline solution, it can roughly detect the tensile strength. That is to tie the yarn into a knot and then pull it hard. If it can be easily broken, it means The tensile strength of the product is relatively poor. If it cannot be easily broken, it means that the tensile strength of the product is relatively good.
Fiber Glass products have excellent performance and are widely used. They have become an indispensable raw material in construction, transportation, electronics, electrical appliances, chemical industry, metallurgy, sports, environmental protection, military industry and national defense.
