Glass tube production Fiberglass Poles Corrosion resistant High
Glass fiber (English name: glass fiber or fiberglass) is a kind of
performance of inorganic non-metallic
materials, a wide range of advantages of good insulation, heat
resistance is strong, good corrosion
resistance, high mechanical strength, but the drawback is crisp,
poor wear resistance.
It is a glass ball or waste glass as raw materials by high
temperature melting system, wire drawing, winding,
weaving and other manufacturing processes, its monofilament
diameter of a few microns to 20 meters
microns, the equivalent of a human hair 1/20-1/5, each bundle fiber
original SiDou consists of hundreds
or even thousands of root monofilament.
The reinforced material glass fiber is often used as a composite
material, electrical insulation and heat
insulation materials, substrate and so on various fields of
Plus or minus 0.1 mm, if you have special tolerance requirements,
The nature of the
※ Glass fiber as reinforcement of reinforced plastic materials, the
biggest characteristic is tensile
strength.Tensile strength under standard condition is 6.3 ~ 6.9
g/d, moist condition 5.4 ~ 5.8 g/d.
The density of 2.54.Good heat resistance, the temperature of 300 ℃
have no impact in strength.
Have excellent electrical insulation, is senior electrical
insulating materials, also used for insulation
and fire protection shielding material.Only commonly by
concentrated alkali, hydrofluoric acid and
concentrated phosphoric acid corrosion.
The main composition of silica, alumina and boron oxide and
magnesium oxide, calcium oxide, sodium
oxide, etc., according to the amount of alkali content, in the
glass can be divided into non-alkali glass fiber
(0% ~ 2% sodium oxide, aluminum borosilicate glass), the alkali
glass fiber (8% ~ 12% sodium oxide,
boron or boron sodium calcium silicate glass) and high alkali glass
fiber (more than 13% sodium oxide,
sodium calcium silicate glass).
