Drain board filter cloth manufacturing technique and prepared filter cloth

Abstract

The invention provides a drain board filter cloth manufacturing technique and a prepared filter cloth, and relates to the technical field of drain board filter cloth production. The method is mianly used for improving filtration coefficients of the drain board filter cloth to enhance the water absorption capability of the drain board filter cloth. According to the drain board filter cloth manufacturing technique, a liquid chemical spraying process is added between a spun-laid process and a hot pressing roller process of a traditional filter cloth production line. By means of a spraying device, a liquid chemical which is formed by mixing a hydrophilic agent with water in the proportion of 8:100 is evenly sprayed on the surface of the filter cloth in a mist mode. The drain board filter cloth manufacturing technique increases the filtration coefficients of the filter cloth on the basis that immovable original parameters and original production processes of the filter cloth are not changed, resource are saved, and the overall working performance of a drain board is improved.

Description

technical field [0001] The invention relates to the field of production technology of drainage board filter cloth, in particular to a production technology of drainage board filter cloth and the obtained filter cloth. Background technique [0002] Non-woven materials are widely used in filtration and water penetration. For example, in wrapping plastic drainage boards, non-woven fabrics are widely used as filter cloths, which can achieve the dual functions of filtering out sediment and penetrating water. However, when using During the process, we found that when the traditional non-woven fabric was used as a filter cloth, due to its low water seepage, the overall performance of the drainage board was not satisfactory. During construction, due to the poor permeability of the filter cloth and the drainage efficiency of the drainage board Low, resulting in a long period of time for consolidating the foundation, delaying the construction period, and consuming manpower and financi...
