The heavy oilpollution cleansing agent comprises, in 100 parts by weight, 2-5 parts of potassium carbonate, 3-6 parts of sodium carbonate, 2-4 parts of potassium silicate, 3-6 parts of tetrapotassium pyrophosphate, 10-30 parts of surfactants, 5-10 parts of solubilizers, 1-4 parts of sterilizing preservatives, 4-8 parts of lipase and 27-70 parts of deionized water. The preparation method of the heavy oil pollution cleansing agent includes the steps: (1) pre-mixed solution preparation; (2) surfactant addition; (3) solubilizer addition; (4) lipase and sterilizing preservative addition.

Description

technical field [0001] The invention relates to the technical field of attachments for oil stain cleaning agents, in particular to a heavy oil oil stain cleaning agent and a preparation method thereof. Background technique [0002] As everyone knows, heavy oil greasy dirt cleaning agent and preparation method thereof are a kind of obstinate greasy dirt accumulated on the surface and interior of the workpiece surface and internal accumulation in the various production and processing processes used for removing automobiles, machinery, electronics, metallurgy and construction, to ensure the normal operation of the operation. [0003] The accumulation of heavy oil and oil on the surface of the workpiece will affect the normal use of the workpiece. If the heavy oil and oil accumulate on the inner wall of the fuel transportation pipeline and fuel nozzles and other transportation parts if it is not cleaned for a long time, it will easily cause obstacles to oil transportation and cau...

Problems solved by technology

[0003] The accumulation of heavy oil and oil on the surface of the workpiece will affect the normal use of the workpiece. If the heavy oil and oil accumulate on the inner wall of the fuel transportation pipeline and fuel nozzles and other transportation parts if it is not cleaned for a long time, it will easily cause obstacles to oil transportation and cause a sharp increase in local pressure in the fuel transportation pipeline. Partial parts of the workpiece are in a high-pressure state for a long time, which is prone to blasting of the transportation pipeline, causing equipment failure or even paralysis, causing unnecessary losses, and more serious safety accidents, leaving irreparable losses. Therefore, the equipment is regularly inspected for heavy oil pollution. cleaning is necessary

[0004] In the early days, organic solvent fuels such as gasoline and kerosene were used to clean up heavy oil pollution, but this method caused a lot of waste of resources, and the sustainability and safety were poor.

[0005] In recent years, oil stain cleaning agents are mostly prepared by combining surfactants and alkaline chemical reagents. Although the oil stain cleaning agents prepared by this method have a high removal rate of oil stains, most of the commonly used surfactants are chlorinated. Hydrocarbons and phosphorus-containing substances, chlorinated hydrocarbons have certain toxicity, and the use safety is poor, and the waste water after cleaning with cleaning agents is troublesome to deal with, the cost is high, the rationality of use is poor, and the treatment is not thorough. The discharge of waste water containing toxic substances such as chlorinated hydrocarbons into the environment is likely to cause water pollution, which poses a threat to the human body and the environment, and is less safe to use; most of the alkaline substances contained in the oil cleaning agent prepared by this method use sodium hydroxide , sodium hydroxide has strong alkalinity, and it also has a certain corrosion effect on the workpiece when degreasing, causing damage to the surface of the workpiece, which has certain potential safety hazards, and reduces the service life of the workpiece at the same time, resulting in increased cost; the prepared by this method The cleaning agent has a short storage period and needs to be used within a certain period of time, so the rationality of use is poor
