Overview of fiberglass?

Glass fiber is a kind of inorganic non-metallic material with excellent performance. Its advantages are good insulation, heat resistance, corrosion resistance and high mechanical strength. It is made of pyrophyllite, quartz sand, limestone, dolomite, boronite and magnesite by high temperature melting, drawing, winding, weaving and other processes, its filaments range in diameter from a few microns to zero microns, about one-twentieth to one-fifth the size of a human hair, and each bundle of filaments consists of hundreds or even thousands of individual filaments. Glass fibers are commonly used as reinforcements in composites, electrical insulation and thermal insulation materials, circuit boards and other areas of the national economy. Its main ingredients are silicon dioxide, aluminium oxide, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. , they can be divided into alkali-free glass fibers (0%-2% sodium oxide, aluminium Borosilicate glass) , medium-alkali glass fibers (8%-12% sodium oxide, sodium-calcium silicate glass with or without boron) and high-alkali glass fibers (over 13% sodium oxide, sodium-calcium silicate glass) . Raw materials and applications: glass fiber than agricultural production system fiber high temperature, non-flammable, anti-corrosion, Heat Insulation, sound insulation, high tensile strength, good electrical insulation. But brittle, poor wear resistance. Used to make reinforced plastics or reinforced rubber, glass fibers as reinforcements have the following characteristics that make them far more widely used than other types of fibers, the following are some of its features:

(1) high tensile strength, low elongation (3%) .

(2) high elastic coefficient and good rigidity.

(3) the elastic limit has a large elongation and high tensile strength, so it has a large absorption of impact energy.

(4) it is an inorganic fiber with good chemical resistance and noncombustibility.

(5) little water absorption.

(6) good scale stability and heat resistance.

(7) good processing, can be made into strands, bundles, felt, weaving and other forms of products.

(8) transparent to light.

(9) development of a surface treatment agent with good adhesion to the resin.

(10) cheap.

(11) non-flammable, high temperature can be melted into glass beads.
