Abstract

The invention discloses a production technology for coated glass fiber gridding cloth. The production technology comprises the following steps: weighing raw material for standby use according to a formula; stirring raw materials by a stirrer to enable raw materials and auxiliary materials to be evenly mixed; then, through a vacuum material suction device, continuously conveying mixed raw materialsto a screw extruder; after the raw materials are molten and compressed by the screw extruder, forming fusant of a viscous state, and then, conveying to a fusant filter through a fusant pipeline to befiltered; sending the fusant into a metering pump, controlling by the metering pump to be sent into a spinning box body, carrying out a spinning operation to obtain a silk bundle, and carrying out airflow traction on the silk bundle to form a fiber network blank. The coated glass fiber gridding cloth has the advantages of good alkali resistance, flexibility and warp and weft direction height tensile resistance, good chemical stability, alkali resistance, cement etching resistance, other chemical corrosion resistance, high strength, high modulus, light weight, good size stability, stiffness, flatness, small possibility of shrinkage strain and good positioning performance.

Description

technical field [0001] The invention relates to the technical field of mesh cloth production technology, in particular to a production technology of coated glass fiber mesh cloth. Background technique [0002] Glass fiber mesh cloth is based on glass fiber woven fabric and coated with polymer anti-emulsion immersion coating. Therefore, it has good alkali resistance, flexibility, and high tensile strength in warp and weft directions, and can be widely used in thermal insulation, waterproofing, and crack resistance of internal and external walls of buildings. The glass fiber mesh cloth is mainly alkali-resistant glass fiber mesh cloth. It is made of medium-free alkali-free glass fiber yarn (mainly composed of silicate and good chemical stability) through a special organizational structure-leno tissue. Afterwards, it is subjected to high-temperature heat-setting treatment such as anti-alkali solution and reinforcing agent; however, the strength of the existing mesh cloth canno...
