How to use metal cleaner properly
In the maintenance of agricultural machinery, the traditional cleaning method is to use gasoline, diesel or kerosene to clean parts. This not only consumes a lot of fuel, but also has disadvantages such as high costs, insecurity, and harm to health. Metal cleaning agent as a new type of industrial washing, it can replace petrol, diesel or kerosene cleaning metal equipment and parts, with the advantages of fuel economy, safety, low cost, clean, good cleaning, good effect. First, commonly used metal cleaning agent and features 1.8112 agricultural cleaning agent. Powdery, strong emulsifying and dispersing performance, good detergency and rinsing performance, cleaning at room temperature. 2.77-3 dry powder metal cleaner. Powder, suitable for tractors, can be cleaned at room temperature, excellent decontamination ability. 3. Universal metal cleaner. Paste, decontamination, anti-rust ability. 4. TX-1 metal cleaning agent. Powder, anti-rust, good lubrication, emulsification, dispersion properties. 5.8318 metal cleaning agent. Powdery, good rust resistance. 6.803 metal cleaner. Liquid, strong rinsing performance. Second, the use of metal cleaning agent 1. Prepare a suitable concentration. The effect of the metal cleaning agent is related to the concentration of the cleaning solution, but when the concentration is increased to a certain value, the cleaning performance will not be significantly improved. Different parts should be formulated with different concentrations of cleaning fluid. General parts cleaning, the concentration of 2% to 3% is appropriate; cleaning heavy scale parts, the concentration of 5% is appropriate; after cleaning bridge gear and shaft parts, the concentration of 3% to 4% is preferred. 2. Control and master the temperature. In a certain temperature range, the metal cleaning agent is conducive to the dissolution of grease and grease. Therefore, cleaning should be carried out strictly according to the appropriate temperature range specified by various metal cleaning agents. Summer cleaning general parts can be carried out at room temperature, the spring and autumn season should be properly heated or prepared with warm boiled water, the winter must be heated B to clean heavy-duty parts, the temperature should be properly increased. If using 8112 cleaning agent, the temperature should be controlled between 65 ~ 70 °C, the washing effect will be better. Heating can be done by dipping or directly heating the water, depending on the circumstances. 3. Master the correct cleaning method. After the cleaning solution is properly prepared, two washing containers are used for rough washing and fine washing. Before cleaning, the parts with thick dirt and carbon deposits on the surface shall be scraped and rubbed first, and then immersed in rough washing containers for a certain period of time, followed by rough washing to fine washing. When cleaning, clean the precision parts first and then clean the general parts. When cleaning the water channels and oil passages of parts such as the crankshaft, pressure guns or other injection tools are preferably used for pressure flushing. After cleaning for a certain period of time, the cleaning solution in the fine washing container should be poured into the rough washing container, and then replaced with a clean cleaning solution to ensure the quality of the fine washing. The pH value should also be checked when it is used. If the pH is less than 7, the cleaning agent should be added to ensure the cleaning quality. 4. Do not use spent cleaning agent. Pay attention to the validity period when purchasing and using, do not use the invalid cleaning agent. Metal cleaning agents should be prepared quantitatively and they should be used as they are. If the amount of cleaning fluid after scrapping is small, there will be little environmental pollution; if the amount is large, it will pollute the environment and waste liquid treatment is required. The cleaned agricultural machine parts should be wiped or dried before use.
