Abstract

The utility model relates to the technical field of glass fiber, and particularly discloses a glass fiber screen cloth, which comprises a plurality of warps and wefts, wherein the warps and wefts are all glass fiber yarns which are puffed by glass fiber yarns, and steel wires are embedded in each puffed glass fiber yarn; and the plurality of warp yarns and the plurality of weft yarns are woven into a bulked glass fiber mesh cloth, and two sides of the bulked glass fiber mesh cloth are provided with adhesive layers. The expanded glass fiber mesh cloth of the utility model adopts expanded glass fiber added with steel wires to be interwoven into mesh cloth, which not only can play a good filtering effect, but also can ensure the strength of the mesh cloth and improve the service life of the mesh cloth; in addition, the surface of the expanded glass fiber mesh cloth is only coated with less than 0.5% of adhesive, so that the smokeless effect is achieved when the expanded glass fiber mesh cloth is used at high temperature.

Description

Expanded glass fiber mesh

Technical Field

The utility model belongs to the technical field of glass fiber, specifically a popped glass fiber screen cloth.

Background

The bulk glass fiber filter cloth, glass fiber filter cloth for short, is composed of bulked yarns. The yarn is fluffy, the covering capability is strong, the air permeability is good, so the filtering efficiency can be improved, the filtering resistance is reduced, the dust removal efficiency can reach more than 99.5 percent, and the product is mainly used for high-temperature atmospheric dust removal, valuable industrial dust recovery and the like. The strength of the traditional alkali-free coated glass fiber filter cloth is relatively reduced after being expanded, and the smoke-free effect after high temperature is difficult to achieve, so that the expanded glass fiber mesh cloth which has high strength and can achieve the smoke-free effect when meeting high temperature needs to be provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a puffed glass fiber screen cloth, intensity is high, and the filter effect is good, can reach the effect of no flue gas when using moreover.

For solving the technical problem, the utility model provides a puffed glass fiber screen cloth, including a plurality of warps and a plurality of woofs, warp and woof are the puffed glass fiber yarn after the glass fiber yarn is popped, every the embedded steel wire that is equipped with of puffed glass fiber yarn, a plurality of warp and a plurality of the woof are interweaved into puffed glass fiber screen cloth, the two-sided coating of puffed glass fiber screen cloth has the adhesive.

Further, the volume of the bulked glass fiber yarn is 1.2-3 times of the volume of the glass fiber raw yarn.

Furthermore, the density of the expanded glass fiber mesh cloth is 15 multiplied by 8 pieces/25 mm, the thickness is more than or equal to 1.4mm, and the mass per unit area is more than or equal to 1200g/m²。

Further, the warp and the weft are both single-ply glass fiber raw yarns synthesized by 8 strands of 138tex yarns or double-ply glass fiber raw yarns synthesized by 4 strands of 138tex yarns.

Further, the total combustible content of the expanded glass fiber mesh cloth is less than 0.5%.

Furthermore, the steel wire is a high-strength stainless steel wire, the diameter of the steel wire is 0.08-0.18mm, and the tensile strength is more than or equal to 1960 MPa.

The utility model has the advantages that: the expanded glass fiber mesh cloth of the utility model adopts expanded glass fiber added with steel wires to be interwoven into mesh cloth, which not only can play a good filtering effect, but also can ensure the strength of the mesh cloth and improve the service life of the mesh cloth; in addition, the surface of the expanded glass fiber mesh cloth is only coated with less than 0.5% of adhesive, so that the smokeless effect is achieved when the expanded glass fiber mesh cloth is used at high temperature.
