Three major uses of glass rod

1. When using mesh to control cracks in external wall insulation, not only the insulation layer material is required to have a certain tensile strength and ultimate stretch, but also the crack-resistant protective layer material is required to have sufficient tensile strength. For this reason, when choosing "glass rod", it is necessary to pay attention to whether the tensile strength of the glass rod itself meets the standards.

2. The use of "grid cloth" compounded in the plastering mortar: on the one hand, it can effectively increase the tensile strength of the protective layer, on the other hand, it can effectively disperse the stress, and can disperse the wide cracks that may have occurred into many Fine cracks, thus forming its anti-cracking effect. The surface coating material and coating amount are of great significance to its alkali resistance, and the Fiber Glass variety is decisive for long-term alkali resistance.
3. Quality identification of glass rod: The Fiber Glass of the worst "glass rod" is usually made of waste glass from some beer bottles. The production process is clay crucible drawing, which is a production process prohibited by the state. The surface coating It is also not an alkali-resistant lotion. From an intuitive point of view: the workmanship is relatively rough, and generally sold in large quantities in the market. The length is often insufficient, the weight is insufficient, and it breaks after folding twice. The joints are not strong and easy to shift, and it is easy to puncture the skin.
Standard high-quality "glass rod" uses platinum Fiber Glass as the base material, and both the selection of materials and the weaving process are very particular. The coating emulsions used have good alkali resistance. The excellent alkali resistance and high longitudinal and latitudinal tensile strength make the product have good hand feel and good construction conformity, and can greatly reduce the amount of plastering mortar.
