Abstract

The invention discloses a heat-resisting dust collecting bag. The heat-resisting dust collecting bag comprises a bag body and a bag basket inside the bag body, wherein the bag basket is in a hollow-out column structure provided with support bars; the mouth of the bag body is arranged at the top of the bag basket in a hooping mode; the inner diameter of the bag body is smaller than the diameter ofthe cross section of the bag basket. According to the heat-resisting dust collecting bag, potassium titanate whisker and nano titanium dioxide particles achieve synergistic effects to fill and modifypolytetrafluoroethylene resin and further to effectively reduce adhesive abrasion and to prolong the service life; besides, matched application of samarium oxide and gamma-methacryloxy propyl trimethoxyl silane can enhance the interface bonding force among glass fiber, carbon fiber and the polytetrafluoroethylene resin, to improve the modification effects of the glass fiber and the carbon fiber onthe polytetrafluoroethylene resin, to improve breathability, heat resistance and mechanical strength, and to endow the heat-resisting dust collecting bag with the advantages of being age-resistant, heat-resistant, high in mechanical strength and good in dust removing effects.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a high-temperature-resistant dust-removing cloth bag. Background technique [0002] In today's world, due to various problems such as soil damage, climate change, energy waste and greenhouse effect, the intensity of environmental protection is gradually increasing, so the development and application of environmental protection equipment are also increasing. The bag filter is the most common type of environmental protection equipment. Therefore, the structure is simple and the process parameters are relatively low. It has become the most popular type of filter. The dust filter bag is a key part of the operation of the bag filter. . However, the existing dust filter bags are poor in high temperature resistance. When used in some special environments, the excessively high temperature will cause the filter bags to bend and wrinkle, thereby affecting normal use. Co...
