What is Fiberglass?
Summary of Materials
Fiberglass, referred to as "Fiberglass", is a new material for reinforcement and a metal substitute material. The diameter of its monofilament is several microns to more than 20 microns, which is equivalent to 1/20-1/5 of a hair, and each bundle of fiber precursors is composed of hundreds or even thousands of monofilaments.
The fiberglass is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other fields.
When fiberglass is used as a reinforcing material for reinforced plastics, the biggest feature is its high tensile strength. The tensile strength is 6.3~6.9 g/d in standard state and 5.4~5.8 g/d in wet state. Density 2.54g/cm3. It has good heat resistance and has no effect on the strength when the temperature reaches 300°C. It has excellent electrical insulation and is an advanced electrical insulation material. It is also used in heat insulation materials and fire shielding materials. Generally only corroded by concentrated alkali, hydrofluoric acid and concentrated phosphoric acid.
Production process
The fiberglass production process is to grind and homogenize pyrophyllite and other raw materials, directly melt them in a high-temperature kiln to make glass liquid, and then draw them. The wire drawing machine is the key equipment for glass fiber forming, and it is a machine for drawing molten glass into wire. The molten glass flows down through the bushing plate, is stretched at high speed by the wire drawing machine, and is wound into shape in a certain direction. After subsequent drying and interlacing, there will be extremely tough fiberglass products.
Material properties
advantage:
Fiberglass has the characteristics of non-combustibility, corrosion resistance, heat insulation, sound insulation, high tensile strength, and good electrical insulation. It is widely used and has broad applications in construction, automobiles, ships, chemical pipelines, rail transit, and wind power Application prospect.
Application cases
The building facade modules are made of white cement and fiberglass, etc.
