Analysis Of The Application Of Fiberglass Mesh
01 What is Fiberglass Mesh?
Fiberglass mesh is a reinforcing material made from alkali-resistant fiberglass yarn as the base material, woven using a special process to form a regular mesh structure, and then coated with an alkali-resistant emulsion.
02 Why Do Walls Crack Easily?
Many people believe that "wall cracks are caused by poor construction." However, this isn't entirely true. Over long-term use, walls are constantly affected by various external factors:
01 Temperature Changes Leading to Thermal Expansion and Contraction: Wall materials repeatedly expand and contract with temperature changes. Over time, this accumulation creates stress concentration in weak areas, eventually leading to cracks.
02 Natural Settlement of the Building Structure: Cement naturally shrinks in volume during hydration and hardening. This drying shrinkage stress causes cracks in the plaster layer.
03 Humidity Changes: High humidity causes walls to absorb water and expand, then shrink as they dry. This cycle repeatedly undermines the stability of the base layer, resulting in fine, mesh-like cracks.
03 Advantages of Fiberglass Mesh
01 Improved Crack Resistance
The mesh structure effectively absorbs shrinkage stress in mortar, reducing the risk of crack propagation.
02 Enhanced Overall Wall Strength
Adding mesh significantly improves the overall strength of the plaster layer, reducing later cracking.
03 Better Alkali Resistance
Mesh treated with alkali-resistant emulsion can maintain its strength for a long time and is less prone to aging.
04 High Construction Efficiency
Easy to install during construction, less prone to bubbling and curling, helping to improve construction efficiency.
04 Applications of Fiberglass Mesh
Currently, fiberglass mesh is widely used in:
01 External Insulation Systems (EIFS)
It evenly distributes stress, preventing cracking and detachment of the external insulation system due to temperature differences or impacts.
02 Wall Plaster Reinforcement
It significantly improves the overall tensile strength of the plaster layer, effectively inhibiting the formation of drying shrinkage cracks and micro-cracks.
03. Stone Backing Reinforcement: Increases the flexural strength and impact resistance of the slabs, reducing the risk of breakage during
transportation and installation.
04. Waterproofing System: Enhances the tensile and puncture resistance of the waterproofing layer, ensuring a durable and reliable seal.
05. How to Choose High-Quality Mesh Fabric?
The quality of mesh fabric products on the market varies greatly. When purchasing, it is recommended to focus on the following aspects:
Raw Materials: High-quality fiberglass yarn determines the basic performance of the product.
Weight: Choose the appropriate weight according to different application scenarios, such as: 60g, 75g, 90g, 110g, 145g, 160g. Different weights correspond to different construction requirements.
Mesh Size: Common specifications include:
4×4 mm, 5×5 mm, and custom sizes. A reasonable mesh size can balance reinforcement effect and construction convenience.
Alkali Resistance: Alkali resistance directly affects the long-term service life of the product and is also an important indicator for judging product quality.
