Uses of Glass Fiber Cloth
1. Medium-Alkali Glass Fiber Cloth
Medium-Alkali Glass Fiber Cloth (abbreviated as Medium-Alkali Cloth) is woven from medium-alkali yarn and is suitable for use as fiberglass reinforced plastic (FRP) base fabric, plastic-coated and rubber-coated base fabric, asphalt felt base fabric, air duct base fabric, waterproofing, pipe wrapping, wall covering base fabric, acid filter cloth, reinforced mesh, and TV projection screen fabric. Medium-Alkali Cloth is made of soda-lime silicate glass with an alkali metal oxide content of 12 ± 0.4%. Substitution of other types of sizing agents or changes in the sizing content is a matter of negotiation between the supplier and the buyer.
2. Medium-Alkali Glass Fiber Wrapping Cloth
Suitable for corrosion protection, corrosion resistance, and thermal insulation of various types and specifications of pipelines and storage tanks exposed to highly corrosive media in power plants, oil fields, chemical industry, papermaking, and environmental protection, as well as for FRP pipe construction.
3. Alkali-Free Glass Fiber Cloth
Suitable for use as a reinforcement material for electrical insulating mica products, electrical insulating varnished cloth, and fiberglass reinforced plastics. E-glass cloth is made from aluminoborosilicate glass, with an alkali metal oxide content of no more than 0.8%. When drawing raw glass fiber yarn, a paraffin emulsion is used as the sizing agent, with a content of no more than 2.2%. Any substitution of other sizing types or changes in the sizing content is a matter of negotiation between the supplier and the buyer.
4. Medium-alkali/E-glass Fiber Grid Cloth
This product, made with a carefully selected resin and formula, boasts pressure resistance, corrosion resistance, aging resistance, long service life, lightweight, high strength, impermeability, thermal insulation, non-toxicity, and a smooth surface. It is widely used in the petroleum, chemical, textile, printing and dyeing, power, transportation, food, brewing, synthetic materials, water supply and drainage, seawater desalination, and irrigation industries. It is primarily used in the production of various integral FRP equipment, including FRP storage tanks, pickling tanks, electroplating tanks, corrugated tiles, honeycomb fillers, flat panels, and inorganic glass. It also manufactures FRP cooling towers, acid gas purification towers, water tanks, and a series of FRP centrifugal, axial, and roof fans. It can also be used in the production of filament-wound FRP piping. The company also offers contract manufacturing for various FRP lining and corrosion protection projects, including FRP aircraft escalators, submersible pumps, FRP motor sheathing, automotive instrument panels, trash cans, electric meter boxes, and stools.
How is glass fiber produced?
There are two main glass fiber production processes: the two-stage crucible drawing method and the single-stage tank kiln drawing method.
The crucible drawing method involves a complex process. Glass raw materials are first melted at high temperature to form glass pellets. The pellets are then melted again and drawn at high speed to produce glass fiber strands. This process has drawbacks such as high energy consumption, unstable forming processes, and low labor productivity, and has been largely eliminated by large-scale glass fiber manufacturers.
The tank kiln drawing method melts raw materials such as pyrophyllite in a kiln to form a glass solution. After air bubbles are removed, the solution is transported through a channel to a multi-porous bushing plate, where it is drawn at high speed to produce glass fiber strands. The kiln can be connected to hundreds of bushing plates through multiple channels for simultaneous production. This process is simple, energy-efficient, stable, and highly efficient, making it suitable for large-scale, fully automated production. It has become a mainstream international production process, producing over 90% of global glass fiber production.
