Suggestions on the Use and Identification Methods of Fiberglass Mesh

Fiberglass mesh is widely used in many fields, but many people do not know its specific use or identification methods. This article will briefly introduce the usage and identification methods of fiberglass mesh so as to better use fiberglass mesh at work.

Functions and Standards of Fiberglass Mesh Tape

Currently, the fiberglass mesh used for exterior wall insulation systems on the market weighs about 160 g per square meter. When controlling cracks in external wall insulation, not only the insulation layer material is required to have a certain tensile strength and ultimate tensile strength, but also the crack-resistant protective layer material is required to have sufficient tensile strength. For this reason, when choosing alkali-resistant fiberglass mesh, it is necessary to pay attention to whether the tensile strength of the alkali-resistant fiberglass mesh itself meets the standards.
The use of alkali-resistant fiberglass mesh compounded in the plastering mortar can effectively increase the tensile strength of the protective layer. On the other hand, it can effectively disperse the stress and disperse the wide cracks that may have occurred. Fine cracks, thus forming its anti-cracking effect. The surface coating material and coating amount are of great significance to the alkali resistance of fiberglass mesh, and the fiberglass variety is decisive for long-term alkali resistance.

Suggestions During the Use of Fiberglass Mesh Tape

The overlap width between alkali-resistant mesh cloths should not be less than 100 mm. The alkali-resistant mesh cloths at the inner corners should be pressed and overlapped. The width should be ≥100mm and the width at the outer corners should be ≥100mm. During construction, the alkali-resistant mesh cloth should be laid flat, without wrinkles, and the mortar fullness should reach 100%. At the same time, it should be smoothed and straightened, and the squareness and verticality of the yin and yang corners should be maintained.
The first floor is reinforced with 240g double-layer mesh cloth, the door and window openings are reinforced at a 45° diagonal, the length of the overlap between the fireproof isolation belt and the large surface is not less than 100mm, and the insulation terminal alkali-resistant netting size is not less than 100mm.

Identify the Quality Problems with Alkali-Resistant Fiberglass Mesh

1. The worst fiberglass mesh cloth. Its fiberglass fibers are usually made of waste glass from beer bottles. The production process is clay crucible drawing, which is a prohibited production process, and the surface coating is not alkali-resistant emulsion. 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. This type of mesh cloth generally loses its strength after two months when used in the insulation layer. If the mortar is knocked out and the mesh cloth is taken out, the fiberglass yarn will turn into powder with just a slight grinding.
2. There is a kind of imitation platinum fiberglass mesh, also called mixed silk yarn. This is a relatively good imitation of glass fiber, but it is usually made from flat broken glass with good transparency, and the fiber diameter is relatively thin. Sometimes it is difficult to judge its authenticity from the surface, but its quality cannot meet the requirements of real alkali-resistant mesh cloth in exterior wall insulation.
3. Standard, high-quality mesh cloth uses platinum glass fiber as the base material. 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 a good hand feel and good construction conformity, which can greatly reduce the amount of plastering mortar.
4. The scope of use of alkali-resistant páska ze skelného vlákna in exterior insulation systems:
Internal insulation of exterior walls usually uses: 3×3×45g, 5×5×75g
Exterior wall panel insulation system adopts: 5×5×160 grams
The exterior wall rubber powder particle system adopts: 5×5×160 grams
Exterior wall tile facing or insulation layer below two meters: 5×5×240 grams
