As an essential auxiliary material for external wall insulation, fiberglass mesh has excellent crack resistance, tensile resistance, and chemical stability. So where are fiberglass mesh mainly used and what are their functions?
Fiberglass mesh is glass fiber woven with medium alkali or alkali free glass fiber yarn and coated with alkali resistant polymer lotion. Grid cloth has high strength, good alkali resistance, and can resist the decay of alkaline substances for a long time. It is the main reinforcement material for cement concrete products, GRC wall panels, and GRC components.
1、 What are the uses of fiberglass mesh?
1. Fiberglass combined with thermal insulation materials is widely used for insulation, waterproofing, fire prevention, crack resistance, and other purposes on both internal and external walls of buildings. The glass fiber mesh fabric is mainly made of alkali resistant glass fiber mesh fabric, which is made of medium alkali free glass fiber yarn (mainly composed of silicate and good chemical stability) twisted and woven with a special organizational structure (leno structure), and then subjected to high-temperature heat setting treatment such as alkali resistance and reinforcing agent.
2. In addition, fiberglass is widely used in wall reinforcement materials (such as fiberglass wall mesh cloth, GRC wall panel, EPS inner and outer wall insulation board, gypsum board, etc.; reinforced cement products (such as Roman columns, flue, etc.); Granite, mosaic specialized mesh, marble back sticking mesh; Waterproof roll cloth and asphalt roof waterproofing; Reinforce the skeleton materials of plastic and rubber products; Fireproof board; Grinding wheel base cloth; Geogrid for highway pavement; Construction caulking tape and so on.
2、 What is the general use of fiberglass mesh?
1. Newly built wall
In general, after a new wall is built, it needs to be maintained for about a month. In order to save construction time, wall construction is carried out in advance. Many masters hang a layer of fiberglass mesh on the wall before applying latex paint, and then start applying latex paint. The mesh cloth can protect the wall and prevent wall cracking.
2. Old walls
When renovating the walls of an old house, it is generally necessary to remove the original coating first, and then hang a layer of fiberglass mesh on the wall before continuing with the subsequent wall construction. Because the walls of the old house have been used for a long time, there will inevitably be problems with the wall structure. By using grid cloth, the problem of cracks on the walls of the old house can be minimized as much as possible.
3. Wall slotting
Generally, opening wire ducts at home will inevitably cause damage to the structure of the wall, and over time, it is easy to cause the wall to crack. At this point, hanging a layer of fiberglass mesh on the wall and continuing with the subsequent wall construction can minimize the possibility of wall cracking in the future.
4. Wall cracks
Cracks may occur on the walls of your home after prolonged use. For safety reasons, it is necessary to repair the cracks on the walls. When repairing large wall cracks, it is necessary to first remove the wall coating, then use an interface agent to seal the base layer of the wall, and hang a layer of mesh cloth on the wall before continuing wall construction. This not only repairs wall cracks, but also prevents the wall from continuing to crack.
5. Splices of different materials
Partial wall decoration requires the use of different materials for splicing decoration. During splicing, there may inevitably be cracks at the joints. If a fiberglass mesh is laid at the cracks, different wall decoration materials can be well connected.
6. Connection between new and old walls
Generally, there are differences in the connection between new and old walls, which can easily lead to cracks in the latex paint during construction. If you hang a layer of fiberglass mesh on the wall before applying latex paint, and then continue to apply latex paint, you can try to avoid this phenomenon as much as possible.
