Fiberglass Mesh (English name: Fiberglass Mesh or fiberglass) is an excellent performance of inorganic non-metallic materials, a wide range of advantages is good insulation, heat resistance, good corrosion resistance, high mechanical strength, but the disadvantage is the Brittle, poor wear resistance. It is made of glass ball or waste glass as raw material by high temperature melting, drawing, yarn, weaving and other processes made of its monofilament diameter of a few microns to twenty microns, the equivalent of a hair Of the 1 / 20-1 / 5, each bundle of fiber raw silk by hundreds or even thousands of monofilament composition. Fiberglass Mesh is usually used as a composite material in the reinforced materials, electrical insulation materials and insulation materials, circuit boards and other areas of the national economy.
Its main components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., according to the amount of alkali in the glass, can be divided into alkali-free Fiberglass Mesh (sodium oxide 0% to 2% Borosilicate glass), alkali Fiberglass Mesh (8% to 12% of sodium oxide, boron or boron-free silicate glass) and high-alkali Fiberglass Mesh (more than 13% sodium oxide, sodium Silicate glass).
Raw materials and their applications: Fiberglass Mesh than organic fiber temperature is high, non-combustible, anti-corrosion, heat insulation, good sound insulation, high tensile strength, good electrical insulation. But the brittle, wear resistance is poor. Used to make reinforced plastic or reinforced rubber, as a reinforced Fiberglass Mesh has the following characteristics, these features make the use of Fiberglass Mesh far more than other types of fiber, the development speed is also far ahead of its characteristics are listed below:
(1) high tensile strength, elongation is small (3%).
(2) high elasticity coefficient, good rigidity.
(3) elastic limit within the large elongation and high tensile strength, so the absorption of large impact energy.
(4) for the inorganic fiber, with non-flammable, good chemical resistance.
(5) water absorption is small.
(6) scale stability, heat resistance are good.
(7) good processing, can be made into shares, beams, carpets, weaving, and other different forms of products.
(8) transparent through the light.
(9) was developed with a good surface treatment agent for resin adhesion.
(11) is not easy to burn, high temperature can be melted into glass beads.
Fiberglass Mesh according to the shape and length, can be divided into continuous fiber, fixed fiber and glass wool; according to the glass composition, can be divided into alkali, chemical resistance, high alkali, alkali, high strength, high elastic modulus and alkali ( Anti-alkali) Fiberglass Mesh and so on.
The main raw materials for the production of Fiberglass Mesh are: quartz sand, alumina and pyrophyllite, limestone, dolomite, boric acid, soda ash, mirabilite, fluorite and so on. The production method is divided into two categories: one is to make the molten glass directly into the fiber; one is made of molten glass first made of 20mm diameter glass ball or rod, and then in a variety of ways to heat remelting made after the diameter of 3 ~ 80μm very fine fibers. Through the platinum alloy plate by mechanical drawing method of drawing infinite fiber, called continuous Fiberglass Mesh, commonly known as long fiber. Non-continuous fibers made by rollers or air streams are called fixed-length Fiberglass Meshs, commonly referred to as short fibers.
Fiberglass Mesh according to the composition, nature and use, divided into different levels. According to the standard level, E-class Fiberglass Mesh use the most common, widely used in electrical insulation materials; S-level for special fibers.
