Industrial oil cleaning has been the heart of many factory cleaning staff difficult, only choose to meet their own cleaning needsCleaning agentIn order to achieve the effect of high cleanliness. In order to achieve this purpose, it is necessary to clean the workpiece, cleaning equipment,Cleaning agentThe cleaning method should have a good understanding, so that the cleaning work is twice the result with half the effort.
1. cleaning of workpiece
Generally, there are several kinds of workpieces to be cleaned, such as aluminum, copper, iron, zinc alloy, etc. In the production process, the types of dirt on the surface of the workpiece (oil, wax, dust, etc.) 3, whether the structure of the workpiece is complex, whether there are gaps, blind holes 4, whether the surface coating is easy to scratch, easy to fall off 5, easy to rust 6, whether the workpiece is a combined material, such as plastic inlay on the alloy, etc; whether there are special requirements for chemicals (such as prohibited chemicals, environmental protection requirements, acid and alkali, etc.);
2. cleaning conditions
Before starting cleaning, we must first understand the cleaning object and cleaning environment. There are mainly the following points:
1. Pay attention to whether there is residue on the surface when cleaning mechanical workpieces
2. What is the anti-rust and anti-discoloration ability of the equipment, and whether strong alkaline cleaning agent can be used
3. Whether there are surface treatment processes such as electroplating, blackening, anodizing, painting, PVD coating, vacuum coating treatment, etc.
3. cleaning agent selection
Alkaline cleaning agent is an emulsion formed by adding emulsifier to the alkali solution, which can reduce the tension and adhesion of the oil film to the surface of the equipment, so that the oil film is broken into very small oil droplets and no longer returns to the metal surface, thus removing the surface oil. It should be noted that different cleaning agents should be used to clean parts of different materials. Alkaline solutions have different degrees of corrosion to metals, especially for aluminum.
If the equipment needs to prevent rust and corrosion, it is necessary to use water-based metal cleaning agent, which is mainly surfactant and has strong decontamination ability. In addition, there will be some auxiliary agents in the cleaning agent, which can enhance the anti-corrosion and anti-rust ability of the metal cleaning agent.
4. cleaning method
1. Scrub. Put the parts in a container with diesel, kerosene or other cleaning fluid, scrub with cotton yarn or brush with a hair brush. This method is easy to operate, simple equipment, but low efficiency, suitable for single small batch of small parts. Under normal circumstances should not use gasoline, because of its soluble fat, will damage people's health and easy to cause fire.
2. Boiled and washed. Put the prepared solution and the parts to be cleaned into a cleaning pool with appropriate size welded by steel plate, heat it to 80~90 ℃ with a stove under the pool, and boil and wash it for 3~5min.
3. Spray washing. Spray the cleaning fluid with a certain pressure and temperature to the surface of the part to remove the oil. This method has good cleaning effect and high production efficiency, but the equipment is complex, and it is suitable for cleaning parts with less complex shapes and serious grease on the surface.
4. Vibration cleaning. The parts to be cleaned are placed on the cleaning basket or cleaning rack of the vibrating cleaning machine and immersed in the cleaning liquid. The vibration generated by the cleaning machine simulates the manual rinsing action and the chemical action of the cleaning liquid to remove oil stains.
5. Ultrasonic cleaning. By the chemical action of the cleaning liquid and the introduction of ultrasonic vibration in the cleaning liquid, in order to remove oil.
