Abstract

An oil filter paper, comprising a resin with a weight percentage greater than 0 and less than or equal to 25%, an inorganic fiber with a weight percentage greater than 0 and less than or equal to 20%, and a wood pulp fiber with a weight percentage greater than or equal to 55% and less than 100%, and the inorganic fiber is glass A mixture of fiber or glass fiber and ceramic fiber; by adding a certain amount of inorganic fiber composed of glass fiber and ceramic fiber to the wood pulp fiber, this inorganic fiber can adjust the filtration accuracy and air permeability of the oil filter paper, and reduce the pore size of the filter paper , At the same time, it also increases the water absorption and strength of the oil filter paper, so that the oil filter paper can effectively absorb and remove impurities in the oil, and improve the quality and utilization of oil products.

Description

technical field [0001] The invention relates to an oil filter paper. Background technique [0002] With the process of building a well-off society, the country's industrial and agricultural production has developed rapidly, and the oil used in the production of petroleum, automobiles, construction machinery, power generation industry, metallurgical industry and other industries (such as various high-grade lubricants, turbine oil for generator sets, internal combustion engine oil, The amount of power supply transformer oil and heavy machinery hydraulic system oil) is increasing, and after a period of use of various lubricating oils, the solid impurities, moisture, gas and sludge in them will increase, making the quality of the oil continue to deteriorate. Solid impurities will destroy the oil film and accelerate the damage of the equipment. When the particle size of the solid impurities is larger than or close to the friction gap, the damage to the equipment will be particula...
