Embodiment 1

[0045] The aramid microfiber needle-punched filter bag includes a bag body, a bag head and a bag bottom. One end of the bag body is fixed to the bag head, and the other end of the bag body is fixed to the bottom of the bag. The bag body includes a base cloth layer and a protective layer. The protective layer is respectively fixed on both sides of the base cloth layer, and the protective layer is composed of the following components in parts by weight: 50-65 parts of polytetrafluoroethylene concentrated dispersion, 0.8-1.5 parts of coupling agent, 8-15 parts of silicone resin 3-10 parts of antistatic agent, 10-15 parts of antibacterial agent, 0.2-0.5 parts of antioxidant and 40-60 parts of deionized water. After using this component, since the main raw material of the protective layer is polytetrafluoroethylene Concentrate the dispersion, and add a proper amount of coupling agent, silicone resin, antistatic agent, antibacterial agent, antioxidant and deionized water to make the ...

Abstract

The invention provides a preparation method of an aramid superfine fiber needled filter bag. By using the preparation method of the aramid superfine fiber needled filter bag, the technical problems that an existing filter bag has no characteristics of corrosion resistance, antistatic performance, antibacterial performance and the like, can be only used in a simple environment, and is poor in functionality, further, a preparation method for preparing the filter bag does not exist, and the like are solved. The preparation method of the aramid superfine fiber needled filter bag comprises the following steps of a, making an aramid fiber, a glass fiber and polyphenyl thioether into a basic fabric layer of which the surface density is 180g / m<2> to 185g / m<2> through opening, mixing, carding and cross lapping; b, introducing the basic fabric layer into an ordinary singeing and calendering machine to carry out singeing and calendering treatment; c, introducing the basic fabric layer into an ordinary dust removing machine to remove an ash layer and an impurity on a surface; d, weighing to take needed raw materials; f, adding the raw materials into an ordinary agitating machine so as to make an emulsion; g, spray-coating the emulsion on the basic fabric layer through a spray-coating and oven-drying device; h, sewing up a bag body, a bag head and a bag bottom together through an ordinary sewing machine. The preparation method of the aramid superfine fiber needled filter bag has the advantage that the product quality is good.

Description

technical field [0001] The invention relates to a preparation method of an aramid 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 ...
