Fiberglass Mesh Good Sound Insulation, High Tensile Strength

Jun 27, 2017

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.

(10) cheap.

(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.

Glass for the production of Fiberglass Meshs is different from glass for other glass products. The glass composition of commercially available fibers is as follows:


Also known as alkali-free glass, is a borosilicate glass. Is currently the most widely used Fiberglass Mesh glass components, has good electrical insulation and mechanical properties, widely used in the production of electrical insulation Fiberglass Mesh, but also a large number of Fiberglass Mesh reinforced plastic for Fiberglass Mesh, its drawback is easy to be Inorganic acid erosion, it is not suitable for use in acidic environments.


Also known as alkali glass, which is characterized by chemical resistance, especially acid resistance is better than alkali-free glass, but the electrical performance is poor, mechanical strength is less than 10% to 20% of alkali-free Fiberglass Mesh, usually foreign alkali Fiberglass Mesh with a certain The amount of diboric trioxide, and China's alkali Fiberglass Mesh is completely free of boron. In foreign countries, the alkali Fiberglass Mesh is only used to produce corrosion-resistant Fiberglass Mesh products, such as for the production of Fiberglass Mesh surface felt, etc., but also for the enhancement of asphalt roofing materials, but in China's alkali Fiberglass Mesh Fiberglass Mesh production accounted for more than half (60%), widely used in the enhancement of Fiberglass Mesh reinforced plastic and the production of filter fabrics, wrapping fabrics, etc., because of its price is lower than the alkali-free Fiberglass Mesh and have a strong competitive edge.

High strength Fiberglass Mesh

It is characterized by high strength, high modulus, its single fiber tensile strength of 2800MPa, than the alkali-free glass tensile strength of about 25%, elastic modulus of 86000MPa, higher than the E-Fiberglass Mesh strength. With their production of glass steel products used for military, space, bullet-proof armor and sports equipment. But because of the high price, and now in civilian areas can not be promoted, the world production will be about a few thousand tons.

AR Fiberglass Mesh

Also known as alkali-resistant Fiberglass Mesh, alkali-resistant Fiberglass Mesh is Fiberglass Mesh reinforced (cement) concrete (referred to as GRC) rib material, 100% inorganic fiber, non-bearing cement components is an ideal substitute for steel and asbestos. Alkali-resistant Fiberglass Mesh is characterized by good alkali resistance, can effectively resist the erosion of high alkali material in cement, strong grip strength, elastic modulus, impact resistance, tensile strength, high bending strength, nonflammable, frost resistance, temperature , Alkali-resistant Fiberglass Mesh is widely used in high-performance enhanced (cement) concrete in a new type of green environment-friendly enhanced, the use of alkali-resistant Fiberglass Mesh is widely used in high-performance enhanced (cement) concrete in a new type of green environment-enhanced material.
