1. Product Overview
Alkali Resistant (AR) Fiberglass Screen is a high-performance mesh woven from specialized glass fiber yarns and coated with a protective vinyl or acrylic resin. While standard fiberglass screens are designed for general insect protection, the AR version is specifically engineered to withstand highly alkaline environments. It is an essential material in the construction industry, used both for premium insect screening and as a reinforcement layer in architectural renderings and stucco systems.
2. Manufacturing & Craftsmanship
The production process utilizes advanced coating technology to ensure chemical stability:
Glass Fiber Drawing: High-quality glass marbles are melted and drawn into micro-filaments, treated with a sizing agent containing zirconium (in some premium AR versions) to enhance alkali resistance.
Plain Weaving: The filaments are woven into a consistent mesh structure using precision weaving looms.
Plastic Coating Process: The mesh undergoes a thermal setting process where it is dipped in an alkali-resistant polymer. This locks the intersections and creates a shield against chemical erosion.
3. Technical Characteristics
Chemical Stability: Exceptional resistance to alkaline substances found in cement, lime, and mortar, preventing the mesh from becoming brittle or dissolving over time.
Dimensional Stability: The mesh has a very low coefficient of thermal expansion, ensuring it remains flat and does not sag or warp under extreme temperature changes.
Tear Resistance: High tensile strength in both warp and weft directions provides superior protection against accidental impact or wind pressure.
Environmental Health: Non-combustible, rot-proof, and lead-free, ensuring safety for both residential and industrial use.
