Abstract

The invention discloses a special filter element for aqua regia treatment, which comprises a filter element body and an additive, wherein the filter element body consists of the following raw materials in parts by weight: 20-25 parts of polyethylene terephthalate, 10-20 parts of high-density polyethylene plastic, 10-15 parts of polychlorotrifluoroethylene, 25-30 parts of polyarylate and 12-18 parts of polyester resin. The filter element provided by the invention is specially suitable for aqua regia treatment, has a high treatment efficiency, and can maintain a high filtration efficiency afterbeing used for a long time, thereby reducing the replacement frequency of the filter element, and saving the cost.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a special filter element for aqua regia treatment. Background technique [0002] The filter element separates solid particles in liquid or gas, or fully contacts different material components to speed up the reaction time, which can protect the normal operation of the equipment or the cleanliness of the air. When the fluid enters the filter element with a certain specification filter, its impurities are blocked. , while clean fluid exits through the filter element. The liquid filter element makes the liquid (including oil, water, etc.) clean the polluted liquid to the state required for production and life, that is, to make the liquid reach a certain degree of cleanliness. [0003] Generally, filter elements of different materials are selected according to the media to be processed in order to improve the processing efficiency. However, the material of the filter element on ...
