Features of plain woven alkali resistant glass fiber mesh fabric 1. Excellent alkali resistance and waterproof nature, made of materials coated with compound oily paint, which has an over 90% intensity reservation ratio after compounded with low-alkali cement for one week (over 95% in actual tests) 2. Made with plain weaving technology, i.e., glass fiber single yarn coating---winding warping---- plain weaving---- heated molding, for achieving an apparently higher intensity than other intertexture mesh fabrics, as well as square and clear mesh and smooth and plain surface. II. Application of plain woven alkali resistant glass fiber mesh fabric 1. Glass fiber mesh enhanced cement board 2. Exterior wall moisture keeping 3. For other enhanced alkali-resistant application
