It mainly cleans the surfaces of various objects contaminated by oil. The following is a detailed introduction:

Service objects
? Metal parts: such as engine cylinders, machined parts, automobile wheels, etc., are easily contaminated with oil during manufacturing, assembly or use, affecting their performance and subsequent processing.
? Industrial equipment: The surfaces and internal components of equipment such as drill pipes, machine tools, printing machines, injection molding machines, etc., oil pollution will affect the normal operation and heat dissipation of the equipment, and may also cause failures.
? Pipeline system: oil pipelines, industrial drainage pipelines, etc., oil pollution will adhere to the inner wall of the pipeline, reduce the flow area of ??the pipeline, and even cause blockage.
? Buildings and ground: factory workshop floors, kitchen fume ducts, building exterior walls, etc., oil pollution not only affects the appearance, but also may bring safety hazards.

Oil removal method
? Solvent cleaning: Use organic solvents such as gasoline, kerosene, trichloroethylene to dissolve oil pollution, which is suitable for parts with heavy oil pollution and high surface accuracy requirements.
? Alkaline solution cleaning: Sodium hydroxide, sodium carbonate and other alkaline substances are used to react with oil to form a saponification reaction, which converts the oil into a water-soluble substance. It is low-cost and widely used.
? Emulsion cleaning: Through the emulsification effect of surfactants, the oil is dispersed in water to form an emulsion and removed. It is relatively friendly to the environment and has a good cleaning effect.
? Ultrasonic cleaning: The cavitation effect of ultrasound is used to break the tiny bubbles in the liquid to generate impact force, and the oil is peeled off the surface of the object. It is suitable for degreasing small precision parts.

Service process
? On-site investigation: Understand the type of oil, degree of pollution, material of the object, etc., and determine the appropriate degreasing plan.
? Preparation: Prepare the corresponding equipment, materials and protective equipment according to the degreasing method and plan, and build necessary enclosures to prevent the splashing of the cleaning solution.
? Degreasing operation: Carry out environmentally friendly degreasing treatment according to the selected method to ensure that the oil is completely removed. For stubborn oil, multiple cleanings may be required.
? Rinse and dry: Rinse with clean water to remove residual cleaning liquid and oil, and then dry the surface of the object by natural drying, compressed air drying or heating and drying.
? Quality inspection: Check the degreasing effect to ensure that there is no oil residue, corrosion, damage, etc. on the surface of the object, which meets relevant standards and customer requirements. Importance ? Improve product quality: For parts in production and manufacturing, clean degreasing can ensure the quality of subsequent processing, such as better adhesion in painting, electroplating and other processes. ? Ensure normal operation of equipment: After industrial equipment is degreased, it can reduce the occurrence of failures, improve operating efficiency and extend service life. ? Improve the working environment: After degreasing buildings and floors, the risk of slipping can be reduced, creating a clean and safe working environment, while also meeting environmental protection requirements.
