Products Description
Alkali resistant mesh tape is a reinforcing material with alkali resistance properties, usually made of materials such as glass fiber or graphene. This material has excellent alkali resistance, corrosion resistance, aging resistance and other characteristics, making it widely used in fields such as construction and roads.
Here are some detailed information about alkali resistant mesh tape:
Specification
Mesh size: Common sizes include 5x5mm and 4x4mm.
Weight: Depending on different application requirements, the weight of alkali resistant mesh tape also varies, commonly ranging from 80g/㎡ to 160g/㎡.
Width and length: The width and length of the alkali resistant mesh tape can be customized according to actual needs, with a common width of 1000mm and a length ranging from 50m to 200m.
Standard For Alkali Resistant Mesh Tape
The current national standard for external wall insulation technology (JG149-2003) stipulates that the tensile strength of alkali resistant mesh fabric in both the warp and weft directions shall not be less than 750N/50mm, the retention rate of alkali resistant tensile strength shall not be less than 50%, and the weight per square meter shall be ≥ 130 grams.
The JG158-2004 standard requires that the tensile strength of alkali resistant mesh fabric in both the warp and weft directions should not be less than 1250N/50 mm, the retention rate of alkali resistant tensile strength should not be less than 90%, and the weight per square meter should be ≥ 160 grams.
Construction Process
Base wall treatment: Firstly, it is necessary to thoroughly remove floating ash, oil stains, release agents, hollows, and weathered substances on the surface of the base wall that affect wall construction, and ensure that the protrusions on the wall surface are leveled when they are greater than or equal to 10.
Interface mortar: Apply base interface agent mortar on the surface of the base wall.
Construction of insulation layer: According to the design requirements for the thickness of the insulation layer, use rubber powder polystyrene particles as the standard thickness to stick cake and punch reinforcement to control the thickness of the insulation layer.
Construction of anti cracking protective layer and decorative layer: After the insulation layer is cured and dried, apply anti cracking mortar, press in alkali resistant mesh cloth, and finally perform appropriate water spraying curing.
In summary, alkali resistant mesh tape is a high-performance reinforcement material with strong alkali resistance, good stability, and high strength, which can effectively improve the crack resistance and durability of buildings. When selecting alkali resistant mesh belts, their specifications, standards, and construction techniques should be considered to ensure that they meet the engineering requirements.
