A cold wash of vegetable planter. Use kerosene, gasoline, and diesel as cleaning agents, and put these parts in an oil basin with a screen. The oil stains are cleaned with a steel wire brush, and the oil stains sink to the bottom of the basin through the screen. After washing, the parts can be dried in the air. But it should be noted that if you clean the oil stains of the friction plate, you should use a little gasoline to clean it. Oil-based cleaning agents should not be used for oil stains on rubber and leather parts that are not resistant to oil. To save oil and achieve a better cleaning effect, first, clean the surface cleaner, smoother, smaller parts, and then clean the larger parts with heavier oil stains on the surface. The oil can also be divided into several oil basins, divided into several steps: primary washing, secondary washing, and fine washing. The washed oil can be used for the initial washing and can be used after precipitation, to achieve the purpose of fuel-saving.
A hot wash of vegetable planter. Wash with alkali and emulsifier solution after heating. Since engine oil, gear oil, etc. cannot dissolve in alkaline solutions but can form emulsions, it is necessary to add emulsifiers to alkaline solutions (sodium silicate, soap, etc.). The role of the emulsifier is to penetrate the oil layer, weaken the bonding force between the oil and the metal, and cause the oil film to rupture and separate. It is necessary to heat the solution to 70-80°C and immerse part of it in the solution. After cleaning the parts, rinse with 60-80 degree water and dry. The commonly used solution formula for removing oil stains on steel and iron castings is: caustic soda 0.75%, sodium carbonate 5%, trisodium phosphate 1%, soap 0.15%, and the rest is water. Caustic soda solution should not be used for cleaning aluminum parts, but sodium carbonate solution should be used instead.
Clean the vegetable planter with metal cleaner. In recent years, metal cleaning agents have been widely used. They can replace diesel, kerosene, and gasoline to clean parts, and are cheap and safe to use. It can clean metal without rust spots. Metal cleaning agents are divided into acidic, alkaline, neutral, solvent-based, etc. For example, acidic metal cleaning agents are generally used to remove oil from stainless steel surface processing machinery. At room temperature, the oil removal effect is very good. Alkaline metal cleaning agents require high-temperature cleaning, and the cleaning effect at room temperature is not good. In the process of using a metal cleaning agent, pay attention to the type and nature of dirt on the parts, master the concentration and temperature of the cleaning agent, and clean the parts according to the instructions.
