Specific Classification and Uses of Fiberglass

Introduction Specific classification and use of fiberglass Fiberglass is generally classified according to the composition of glass raw materials, monofilament diameter, fiber characteristics, fiber appearance, etc. Fiberglass has a twisted, straight strand

Specific Classification and Uses of Fiberglass

Glass fibers are generally classified according to the composition of glass raw materials, single filament diameter, fiber characteristics, appearance, etc. Fiberglass includes roving, direct roving, cut strands, roving, fiberglass mat, friction material, continuous fiberglass, etc.

1. Classification of glass raw material components: generally distinguished by different contents of alkali metal oxides

(1) Alkali-free fiber (commonly known as E glass): R2O content is less than greater than 0.8 %, is an aluminum borosilicate component. Its chemical stability, electrical insulation properties and resistance are all very good. Mainly used as electrical insulation materials, fiberglass reinforcement materials and tire cables.

(2) Medium alkaline fiber: R2O content is 11.9% to 16.4%. This is a cocomponent of sodium and calcium silicate. Due to its high alkali content, it cannot be used as an electrical insulation material. but its chemical stability and strength are good. Generally used as latex fabric, gingham fabric base material, acid filter cloth, mosquito net base material, etc.

(2) Highly alkaline fiber: glass component with an R2O content equal to or greater than 15%. Such as fiberglass taken from broken flat glass, broken bottle glass, etc. It can be used as waterproof and moisture-proof materials such as battery insulation sheets, pipe wrapping fabrics and felt sheets.

2. Monofilament diameter classification: Glass fiber monofilaments are cylindrical, and the thickness can be expressed by diameter

(1) Thick fiber: Its monofilament diameter is generally 30um

p>(2) Primary fiber: its diamIts single filament diameter is greater than 20 um;

(3) Intermediate fiber: its single filament diameter is 10 to 20 um

(4) Advanced fiber: (also known under the name of textile fiber) its single filament diameter is 3 to 10 um.

3. Classification based on fiber characteristics: high-strength fiberglass; ordinary high temperature resistant fiberglass; (referring to alkali-free and moderately alkaline fiberglass); low dielectric constant fiberglass; conductive fiber, etc.

Glass fiber (original English name: fiberglass or fiberglass) is a non-metallic inorganic material with excellent performance. It has many types and advantages. It has good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. Islandst made from seven kinds of ores such as pyrophyllite, quartz sand, limestone, dolomite, ponite and boronite as raw materials by smelting, drawing, winding, weaving and other high temperature processes. The diameter of its single filament is several microns. at more than 20 microns, the equivalent of 1/20-1/5 of a hair. Each strand of fiber is made up of hundreds or even thousands of unique filaments.
