High-quality alkali-resistant grid cloth has three main indicators, namely alkali resistance, tensile strength, fracture strain, which is the most important alkali resistance. Because in the case of poor alkali resistance, tensile strength and then its strength will also be rapid decline in concrete, can not play the role of anti-cracking. The alkali-resistant mesh performance, mainly by the composition of the yarn mesh and coating the performance of alkali-resistant adhesive to achieve. However, the quality of alkali-resistant mesh on the market varies greatly, fake and shoddy, shoddy phenomenon is worrying.
 
Fiberglass mesh of the glass fiber mesh are the following: First, the use of recycled high alkali glass broken in the clay crucible out of the glass fiber yarn, the yarn strength is low, no alkali performance, the state banned the production ; Second is broken glass ball in the clay pot on the pull out, this kind of yarn is very brittle, and the single fiber thickness difference is very big, so strength can not be guaranteed; three in the process of twisting, the above two yarn or The clay crucible yarn and high quality platinum crucible yarn mixed, so that mesh manufacturers and ordinary consumers is difficult to identify. However, the production of high-quality yarn and inferior yarn mesh, a test can show differences in alkali, poor alkaline products, the basic performance is not up to standard.
