Abstract

The invention discloses a preparation method of ECR ​​glass fiber filter cloth, which comprises the following steps: a. arranging the warp yarns on the warp head used for weaving through a warping machine; b. expanding and loosening the weft yarns through a bulky yarn machine; c. 1. Weave the prepared warp and weft yarns into the filter base cloth through the loom; d. Pass the filter base cloth through the boiling hot water in the hot cleaning unit at a speed of 3-8m / min for thermal cleaning, and then at the same speed Combustion is carried out by passing hot air at 380-420°C; e, coating the surface treatment agent on the filter base cloth; f, drying the filter base cloth coated with the surface treatment agent to obtain ECR glass fiber filter cloth. The invention can not only make the glass fiber filter cloth resist the corrosion of strong acid substances such as concentrated sulfuric acid, concentrated hydrochloric acid and hydrofluoric acid, but also improve the rigidity, high temperature resistance and filtering effect of the glass fiber filter cloth.

Description

technical field [0001] The invention relates to a glass fiber filter cloth, in particular to a preparation method of an ECR glass fiber filter cloth. Background technique [0002] Glass fiber filter material is widely used because of its high strength, stable size, high temperature resistance and high filtration efficiency, but glass fiber also has obvious disadvantages, that is, the fiber is brittle, not resistant to folding, not wear-resistant, and easily corroded by acid , These shortcomings have seriously affected the service life of the glass fiber filter material. [0003] In the prior art, after the glass fiber filter cloth is made, it is usually treated with a surface treatment agent to improve the overall performance of the glass fiber filter cloth and prolong the service life of the filter cloth. For example, the Chinese patent number is "201210276805.X The prior art of "disclosed a kind of glass fiber filter cloth surface treatment agent and glass fiber filter cl...
