High-strength ceramic fiber filter filter-paper

Abstract

The invention discloses high-strength ceramic fiber filter filter-paper. The high-strength ceramic fiber filter filter-paper is prepared from, by weight, 60-80 parts of straw pulp, 1-2 parts of ceramic fibers, 8-10 parts of aluminum silicate fibers, 1-2 parts of sodium tripolyphosphate, 1-2 parts of an antioxidant DSTP, 0.2-0.8 part of erucyl amide, 0.5-0.6 part of zinc borate, 10-18 parts of tencel fibers, 1-2 parts of polyvinyl acetate emulsion adhesive, 1-2 parts of sodium hexametaphosphate, 1-2 parts of folium artemisiae argyi, 1-2 parts of folium isatidis, 0.1-0.2 part of melamine, 15-20 parts of styrene-acrylic emulsion, 2-4 parts of orange peels, 4-8 parts of durian shells, 5-6 parts of sugarcane peels, 1-2 parts of coconut fibers, 3-5 parts of sawdust, 0.02-0.05 part of citric acid, 0.1-0.2 part of zinc nitrate and 0.2-0.5 part of silver nitrate.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a high-strength ceramic fiber filter paper. Background technique [0002] The engine has three types of filters: air, oil, and fuel, generally referred to as "three filters". They are respectively responsible for the filtration of the medium in the engine intake system, lubrication system and combustion system. There are two types of air filters, dry and wet. A dry air filter is a filter that separates impurities in the air through a dry filter element (such as a paper filter element). [0003] The air filter used in light vehicles (including cars and mini-cars) is generally single-stage, and the filter material is filter paper or non-woven fabric. Under the rated air volume flow rate, the original filtration efficiency of the filter element should not be less than 99.5%. Due to the harsh working environment of heavy vehicles, its air filter must be multi-stage. The first st...

Problems solved by technology

[0004] Use low-priced filter paper to make the filter element, because of its large pore size, poor uniformity, and low filtration efficiency, it cannot effectively filter out harmful impurities and endanger your health.
