Abstract

The invention relates to a basalt fiber coating film filter material which is formed by hot-pressing and coating basalt fiber bulk yarn base cloth and a PTFE (Polytetrafluoroethylene) film at a high temperature after the basalt fiber bulk yarn base cloth is subjected to dewaxing, the dipping treatment with a surface treatment solution, and baking, wherein the surface treatment solution is a water-based mixed solution which is prepared from the following components in percentage by weight: 5%-40% of tetrafluorine emulsion, 0.3%-5% of waterproofing agent, 0.05%-5% of coupling agent and the balance of water. The basalt fiber coating film filter material can be used for a long term at a high temperature of 300 DEG C, and can achieve the filtering efficiency of 99.995% for 1-micron or smaller dust.

Description

technical field [0001] The invention relates to an ultra-high temperature, corrosion-resistant high-performance film-coated filter material in the high-temperature flue gas filtration industry, in particular to a basalt fiber film-coated filter material. Background technique [0002] With the development of industry, the working conditions of the high-temperature flue gas filtration industry are becoming more and more complex and diverse. In the face of harsh working conditions, how to perform high-efficiency filtration while ensuring and prolonging the service life of filter bags, ensuring filtration efficiency, and achieving the purpose of environmental protection is a problem. A long-term task is required. [0003] The base material of the existing high-temperature filter material is mainly glass fiber fabric or a mixed fabric of glass fiber and other fibers, and the maximum service temperature is 250°C. In addition, there are needle-punched felts made of chemical fibers ...
