Selection, Identification And Application Of High Quality Glass Fiber Mesh Cloth

(1) Fiberglass Mesh Selection

Glass fiber mesh cloth for the external wall insulation surface strengthening material, the main function is: improve the mechanical strength of the surface layer, ensure the continuity of the resistance of the finish layer, disperse the contraction pressure and insulation stress of the surface layer, avoid stress concentration, resist the natural temperature, humidity changes and accidental impact caused by the surface cracking. Therefore, alkali-resistant glass fiber mesh cloth plays an important function and role in the external insulation system, so the selection of good glass fiber mesh cloth is also an important part of ensuring the comprehensive quality of the external insulation system.

China’s current external wall insulation technical standard (JG149-2003) : The glass fiber net shall not be less than 750N/50mm in the longitudinal and zonal alkali tensile break strength, the alkali tensile break strength retention rate shall not be less than 50%, and the weight per square meter shall not be less than 130 grams. The JG158-2004 glass fiber net shall not be less than 1250N/50 mm, alkali tensile break strength retention rate shall not be less than 90%, weight per square meter ≥160 grams.

At present, the mesh cloth used in the external wall insulation system in the Chinese market weighs about 130g per square meter, and the strength is generally low, and the normal fracture strength is only 1000N/5cm, or even lower. To this end: the technical indicators of the mesh cloth for the external wall insulation project are required to be standardized, and the qualification of the purchased glass fiber mesh cloth must be confirmed before use. In the crack control of external wall insulation, it is not only required that the thermal insulation material should have a certain tensile strength and ultimate tensile strength, but also that the anti-crack protective material should have sufficient tensile strength. Therefore, when choosing glass fiber mesh cloth, it is necessary to pay attention to whether the tensile strength of glass fiber mesh cloth itself meets the standard.

NQ’s glass fiber mesh cloth has significant advantages over common products on the market. It not only meets or even exceeds the current external wall insulation technical standards, to ensure that the longitude and weft alkali tensile break strength and retention rate are at a high level, and the weight per square meter is stable, the strength is higher, the normal breaking strength is far more than 1000N/5cm, providing more reliable mechanical properties. In addition, NQ glass fiber mesh cloth uses high-quality materials and advanced production processes to ensure good alkaline resistance and long-term stability, even in harsh natural environments can maintain excellent performance, effective resistance to temperature, humidity changes and accidental impact, greatly extending the service life of the external insulation system. Its excellent adhesion and construction convenience also make NQ glass fiber mesh fabric an ideal choice for strengthening materials in external wall insulation projects.

(2) The Use Of Fiberglass Mesh Composite In The Plastering Sand Slurry

On the one hand, it can effectively increase the tensile strength of the protective layer, and on the other hand, because it can effectively disperse the stress, the wider cracks that may be generated can be dispersed into many finer cracks, thus forming its anti-cracking effect. The surface coating material and coating amount have important significance on the alkali resistance of the glass fiber mesh cloth, and the glass fiber variety has decisive significance on the long-term alkali resistance.

Glass fiber mesh cloth in the use process:The lap width between the mesh cloth is not less than 50mm, and the mesh cloth at the negative Angle should be pressed into the stubble-lap, and the width is ≥50mm and the positive Angle is ≥200mm. During construction, the glass fiber mesh cloth should be flat, without folds, and the sand slurry fullness should reach 100%. At the same time, the square and vertical degree of the Yin and Yang Angle should be smoothed, straightened, and maintained.

(3) How To Identify Fiberglass Mesh Quality Problems:

The poor glass fiber mesh cloth market price is usually 1.00 yuan -1.60 yuan, his glass fiber is usually made of some beer bottles of waste glass, the production process for clay crucible wire drawing, is prohibited by the state of the production process, the surface coating is not alkali resistant emulsion. From an intuitive point of view: the workmanship is relatively rough, generally in the market volume to sell more, often appear insufficient length, insufficient gram weight, break two times, the contact is not strong and easy to shift, and easy to puncture the skin. This kind of mesh cloth used in the insulation layer generally loses strength after two months, if the sand is knocked off the mesh cloth, as long as a gentle grind, the glass fiber yarn will become powdered.
There is also a kind of imitation platinum glass fiber mesh cloth, also known as mixed silk yarn. This is a good imitation of glass fiber, but it is usually some flat glass with good transparency in the selection of waste glass, and the fiber diameter is relatively thin. Sometimes it is difficult to judge its authenticity from the surface, but its quality does not in any case meet the requirements of the real alkali-resistant mesh cloth in the external wall insulation.
The standard mesh cloth with good quality is made of platinum glass fiber as the base material, and the selection of materials and the weaving process are more exquisite. The coating emulsions used have good alkali resistance. Excellent alkali resistance and high warp and weft tensile strength make the product have good feel and good construction adhesion, and reduce the amount of plaster-sand to a greater extent.

For example, NQ’s glass fiber mesh cloth is of good quality. NQ performs rigorous quality control tests, such as visual testing, coating testing, adhesion testing, etc., and maintains 60-80% strength after 28 days of testing in Naoh, thus guaranteeing high strength, high tensile strength, and lightweight. The surface is coated with sufficient alkali-resistant adhesive, zirconia-containing acrylic emulsion, etc., to improve corrosion resistance. The adhesive is made of German BASF company products, with strength retention rate >90%, elongation rate <1%, and durability of more than 50 years.

The scope of use of glass fiber mesh cloth in external insulation system:

External wall internal insulation is usually used: 3×3×45 grams, 5×5×80 grams
Exterior wall panel insulation system: 5×5× 130g, 5×5× 145g
External wall rubber powder particle system: 5×5×160 grams

(4) Fiberglass Mesh Application

The product has high strength, good adhesion, adhesion and excellent positioning, and is widely used in wall enhancement, external wall insulation, roof waterproof and other aspects, and can also be used in cement, plastic, asphalt, marble, Mosaic and other wall materials, which is the ideal engineering material for the construction industry.

The application of glass fiber alkali-resistant mesh cloth in external wall insulation system

Mainly to prevent the generation of cracks. Due to its excellent resistance to acid, alkali and other chemical substances and high longitudinal and weft tensile strength, the stress of the external wall insulation system can be evenly dispersed, and the deformation of the entire insulation structure caused by the collision and extrusion of the external impulse force can be avoided, so that the insulation layer has a high impulse strength, and is easy to construction and quality control. It plays the role of “soft steel bar” in the insulation system.

At the same time, the excellent performance of alkali-resistant glass fiber mesh cloth is also reflected in its long-term stability and durability. Even in harsh natural environments, such as extreme temperature and humidity changes, wind and rain erosion, it can maintain stable performance and is not easy to age or damage. This stability ensures the long-term use of the external wall insulation system, reducing maintenance and replacement costs caused by aging or damage to the material.

In addition, the alkali-resistant glass fiber mesh cloth also has good permeability, which can effectively prevent the accumulation of water inside the insulation layer and avoid mold, corrosion and other problems caused by it. This not only improves the overall performance of the insulation system, but also prolongs its service life.

In summary, the application of alkali-resistant glass fiber mesh cloth in the external wall insulation system has significant advantages, it can not only effectively prevent the generation of cracks, improve the impact strength of the insulation layer, but also has long-term stability and durability, as well as good permeability. These characteristics make it an indispensable and important material in exterior wall insulation systems.

2, the application of alkali-resistant mesh cloth in the roof waterproof system

In the roof waterproof system, the waterproof medium (such as asphalt) itself lacks sufficient strength, so it is easy to crack and leak under the action of four seasons temperature change, wind and sun exposure and other external forces, so that it can not effectively play a waterproof role. In order to solve this problem, people began to add glass fiber mesh cloth or its composite felt to the waterproof coil.

The addition of alkali-resistant mesh cloth significantly enhanced the weathering resistance and tensile strength of the waterproof coil. Its unique fiber structure and alkali-resistant coating make the mesh cloth able to withstand various stress changes without cracking, thus ensuring the long-term stability and integrity of the waterproof layer. Even in harsh weather conditions, such as extreme high and low temperatures, strong winds, heavy rain, etc., alkali-resistant mesh cloth can maintain its excellent performance and is not easy to age and damage.

In addition, the alkali-resistant mesh cloth also has good water permeability, which can effectively prevent the accumulation of water inside the waterproof layer and avoid the problems such as bubbling and falling off caused by it. This further improves the overall performance and service life of the waterproof system.

In summary, the application of alkali-resistant mesh cloth in roof waterproof system has significant advantages. It can not only enhance the weathering resistance and tensile strength of the waterproof coil, but also withstand various stress changes without cracking, so as to obtain a long-term waterproof effect. This effectively avoids the discomfort and inconvenience caused by roof leakage to the people, and improves the comfort and safety of the building.

The application of alkali-resistant mesh cloth in stone enhancement

In the field of stone applications, especially in the enhancement of materials such as marble or Mosaic, alkali resistant mesh cloth plays a vital role. By covering the back of these stones with fiberglass mesh cloth, it is possible to use its excellent adhesion and positioning properties to achieve uniform distribution of the stress of the stone during construction and application.

The unique structure of the alkali-resistant mesh cloth enables it to effectively absorb and disperse the stress from all directions, thereby preventing the stone from cracks or damage due to uneven stress. This enhanced treatment not only improves the compressive and bending strength of the stone, but also significantly enhances its durability and service life. Even in the case of long-term heavy pressure or frequent external impact, the stone reinforced by alkali resistant mesh cloth can maintain its integrity and stability.

In addition, the alkali-resistant mesh cloth also has good chemical stability, which can resist the erosion of corrosive substances such as acid and alkali, and further protect the stone from damage by environmental factors. This comprehensive enhancement and protection effect makes the alkali-resistant mesh cloth an indispensable and important material in the stone enhancement treatment.

In summary, the application of alkali-resistant mesh cloth in stone strengthening has significant advantages. It can not only evenly disperse the stress of the stone in the construction and application process, play an enhanced role, but also resist the erosion of corrosive substances and protect the stone from damage. These characteristics make the alkali-resistant mesh cloth an ideal choice to improve the performance and service life of stone.
