Problems solved by technology

[0002] Filter materials are widely used in chemical industry, electric power, metallurgy, petroleum, electronic appliances, machinery and other industries. The most common ones are automobile air filters, which are used to filter the air of automobile engines and remove particulate matter and particles in the air. Mechanical impurity components are blocked to prevent these components from entering gasoline, diesel or engine oil to ensure the normal operation of the engine. There are also a large number of filter materials used in the air conditioning system. The existing environmental air pollution is seriously polluted by stone dust, which greatly endangers human health. Air filter materials It can absorb all kinds of harmful particles in the air, prevent them from entering people's living or working environment, reduce the inhalation of harmful substances such as particles in the human lungs, improve people's quality of life, prevent them from entering people's life and work, and reduce the risk of human lung damage. Part of the inhalation of harmful substances such as particulate matter improves people's quality of life and reduces the occurrence of diseases. Another part is used for water filtration or sewage treatment to separate heavy metals or harmful components in water. The existing filter materials mainly include honeycomb ceramics, Filter paper, steel wire mesh, etc., the proportioning function of ceramic filter materials is relatively single, which cannot meet the requirements of continuous technological development
