In the industrial cleaning agent market, metal cleaning agents are used as solvents for cleaning metal parts and equipment, and because they are environmentally friendly and can successfully replace gasoline and kerosene, they account for the majority of the market share. Almost every machine manufacturer will The metal cleaner is used to maintain the equipment, but the cleaning effect does not reach the ideal state due to careless use, which wastes the solution and increases the cleaning cost. So, what is the correct way to use metal cleaners? What should I pay attention to when using it?

一、Common misunderstandings about the use of metal cleaners

    1、Do metal cleaners use stock solution to clean?

Different products use different methods, so be sure to follow the product instructions when using them. Generally speaking, metal cleaners are divided into two types: water-based and solvent-based. Solvent-based cleaning agents are usually composed of hydrocarbon solvents and cannot be diluted with water. The water-based cleaning agent is foamy, and if it is used directly without diluting it with water in a certain proportion, it will produce a lot of foam. In addition, the concentration of water-based cleaning agent is relatively high, if it is used directly, it will give people a very "oily" feeling, and it is not good for the surface of the equipment.  正解：溶剂型使用原液，水基型需要稀释（1：5-10）。

 2、Is the cleaning agent cleaned at room temperature?

Solvent-based cleaning agents are mainly composed of hydrocarbon solvent substances and have a flash point, which cannot be heated and cleaned, so they can only be cleaned at room temperature. The water-based cleaning agent can be heated and cleaned with ultrasonic cleaning agent. Generally speaking, the temperature of the solution is controlled at about 55°C. 正解：溶剂型常温下清洗，水基型可以加热清洗。

 3、Does a simple scrub work?？

Many people think that it is enough to spray the cleaning solvent directly. In fact, there are many ways to use metal cleaning agents. When cleaning, you must make a judgment based on the actual situation. For example, for parts with thick surface dirt and high carbon deposits, first scrape and wipe them, and then immerse them in a cleaning tank for a period of time before heating and cleaning to ensure the removal of stubborn grease. When cleaning, you should clean the precision parts first, and then clean the ordinary equipment parts to ensure that the precision parts can work normally. When cleaning the pipeline, use a pressure gun or other spray tools to first pressurize and flush. After waiting for a while, use a cleaning agent to clean it. After cleaning, the pH value should be tested. If it is acidic, it means that it has not been cleaned and should continue to clean.  

Positive solution: the way of cleaning is changed according to the different cleaning objects.

二、The correct use of metal cleaning agent

     1、Water-based cleaning agent cleaning method

   （1） Spray cleaning: use 1:1-10 according to the degree of oil stains. If the oil stains and grease stains are heavy, spray the metal cleaner directly on the stained surface. After a while, scrub with a scouring pad.

   （2） Dipping: When cleaning equipment with a larger structure, you can put the metal oil cleaner into the sink for manual cleaning.

   （3） Ultrasonic cleaning: When cleaning equipment with a complex structure and small volume, it can be cleaned with an ultrasonic machine. This can easily remove the oil and grease in the equipment, and the cleaning effect is better.

    2、Solvent cleaning agent cleaning method

   （1）According to the actual situation, it can be cleaned by brushing, spraying and soaking.

   （2）Ultrasonic vibration cleaning after soaking (pay attention to control the cleaning temperature), the cleaning efficiency will be higher.
