Abstract

The invention provides a preparation method of a PPS superfine fiber acupuncture filter bag, which solves the technical problems that the existing filter bag does not have the characteristics of flame retardance, antistatic property, high-temperature resistance and the like, only can be applied to a single simple environment and has a single function and a preparation method of the filter bag is unavailable and the like are solved. The preparation method of the PPS superfine fiber acupuncture filter bag comprises the following steps: (a) performing opening, mixing, carding and cross lapping of polyphenylene sulfide and aramid fiber to obtain a base cloth layer with surface density of 170-180g / m<2>; (b) putting the base cloth layer into a common dusting machine and removing the dust and impurities on the surface; (c) weighing the required raw materials; (d) adding the raw materials into a common stirrer to obtain an emulsion; (e) spraying the emulsion on the base cloth layer by a spraying-drying integrated machine, and drying the formed emulsion layer to obtain a protection layer; and (f) sewing the bag body, the bag head and the bag bottom together by a common sewing machine, and processing into the PPS superfine fiber acupuncture filter bag. The preparation method provided by the invention has the advantage of high preparation efficiency.

Description

technical field [0001] The invention relates to a preparation method of a 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 dust coll...
