Abstract

The invention provides a preparation method of a modified PPS (polyphenylene sulfide) superfine fiber needled filter bag and solves the technical problems that, for instance, the prior art has no preparation methods of such filter bag. The preparation method herein comprises the steps of a, opening polyphenylene sulfide and aramid fiber, mixing, combing, performing cross laying to obtain a base cloth layer having surface density of 170-180 g/m<2>; b, feeding the base cloth layer into a common dust collector to remove dust and impurities on the surface; c, weighing the materials in parts by weight; d, adding polytetrafluoroethylene concentrated dispersion, a coupling agent, epoxy phenolic resin, thermosetting acrylic resin, phenylmethyl silicone oil, magnesia, zinc oxide, an antistatic agent and deodorized water into a common stirrer to obtain an emulsion; e, spraying the emulsion to the base cloth layer through a spraying and drying machine; f, sewing together a bag body, a head and abottom via a common sewing machine. The preparation method has the advantage of high preparation efficiency.

Description

technical field [0001] The invention relates to a preparation method of an improved PPS superfine fiber acupuncture filter bag. Background technique [0002] The rapid development of modern industry has brought many material benefits and social benefits to human beings. At the same time, it has also brought serious harm to the environment on which human beings live, especially in the aspect of large amounts of exhaust gas emissions. In order to protect the environment in which human beings live, it is quite necessary to formulate more stringent air emission standards, promote more advanced and more efficient dust removal technology, reduce industrial dust emissions, and improve the atmospheric environment. The filter bag is a key part in the operation of the bag filter, and the cylindrical filter bag is usually hung vertically in the filter bag. In the existing dust collector, the dust is attached to the outer surface of the filter bag. When the dusty gas passes through the...
