Cleaning can be divided into civil cleaning and industrial cleaning according to the scope of cleaning, and the cleaning involved in industrial production all belong to the category of industrial basic cleaning.
Industrial cleaning can generally be divided into the following three ways.
1, according to the cleaning precision requirements, mainly divided into general industrial cleaning, precision industrial cleaning and ultra-precision industrial cleaning three categories.
General industrial cleaning, including car, ship, aircraft surface cleaning, generally only to remove the coarser dirt;
Precision industrial cleaning including a variety of product processing and production process cleaning, a variety of materials and equipment surface cleaning, etc., which is characterized by the ability to remove the tiny dirt particles;
Ultra-precision cleaning including precision industrial production process of mechanical parts, electronic components, optical components and other ultra-precision cleaning, the purpose is to remove the tiny dirt particles.
2, according to the different cleaning methods, can also be divided into physical cleaning and chemical cleaning.
Physical cleaning: the use of mechanics, acoustics, optics, electricity, heat and other principles, relying on the role of external energy, such as mechanical friction, ultrasound, negative pressure, high pressure) in the hit. Ultraviolet light, steam and other methods to remove dirt from the surface of the object.
Chemical cleaning: rely on the role of chemical reactions, the use of chemicals or other solvents to remove dirt on the surface of the object is called chemical cleaning. For example, with a variety of inorganic or organic acids to remove the surface of the object rust, scale, with oxidizing agents to remove the surface of the object stains. Disinfectants can kill microorganisms and remove mold.
Physical cleaning and chemical cleaning have their own advantages and disadvantages, with good complementarity. In the actual application process, the two are usually used in combination to obtain a better cleaning effect.
3, according to the different cleaning media, can be divided into wet cleaning and dry cleaning.
General cleaning in the liquid medium is called wet cleaning, cleaning in the gas medium is called dry cleaning. Most of the traditional cleaning methods are wet cleaning, and dry cleaning, more easily understood by people is also vacuum cleaner. However, in recent years, dry cleaning has developed rapidly. Such as laser cleaning, ultraviolet cleaning, plasma cleaning, dry ice cleaning, etc., are in the field of high, precise and advanced industrial technology is developing rapidly.
