Quality of alkali mesh has 3 main index that alkali resistance, tensile strength and fracture strain, of which the most important is alkali resistance. Because in alkali poor performance, tensile strength to the strong will in concrete rapid decline, not to crack. While the mesh alkali resistance, alkali resistance mainly depends on the composition and coating glue cloth yarn to achieve. However, the current market on alkali resistant mesh quality is uneven in quality, fake and shoddy phenomenon concerns.

Shoddy fiberglass mesh glass fiber yarn has the following several kinds: one is the recycling of high alkali broken glass in the clay crucible pulled out of the glass fiber yarn, the yarn strength is low, no alkali resistance is expressly prohibit the production of countries; second is by broken glass ball in the clay crucible pulling out, the yarn is very brittle and single fiber thickness difference so great strength can not be guaranteed; three is in twisting process, the two kinds of yarn or clay crucible yarn and high quality platinum crucible yarn mixed, make fabric producers and consumers, it is difficult to distinguish. However, the high-quality yarn and coarse yarn production, once alkali resistance experiment can show differences and inferior products, the alkali resistance of basic standards.
