According to the cleaning precision requirements,it can be divided into three categories:general industrial cleaning,precision industrial cleaning and ultra-precision industrial cleaning.General industrial cleaning includes the surface cleaning of vehicles,ships and aircraft.
In general,only rough dirt can be removed.Precision industrial cleaning includes the surface cleaning of materials and equipment in the processing and production of various products.It is characterized by the removal of tiny dust particles.
Ultra-precision cleaning includes precision industrial production.Ultra-precision cleaning of mechanical parts,electronic parts,optical parts,etc.to remove very small dust particles.
Depending on the cleaning method,it can also be divided into physical cleaning and chemical cleaning:using mechanics,acoustics,optics,electrochemistry and thermodynamics.
Relying on the role of external energy,such as mechanical friction,ultrasound,negative pressure,high pressure,impact,ultraviolet light,steam,etc.known as physical cleaning,relying on the role of chemical reactions.
the use of chemicals or other solvents to remove dirt on the surface of the object,known as chemical cleaning,such as the use of a variety of inorganic or organic acids to remove rust on the surface of the object.
The use of oxidizing agents to remove discoloration on the surface of the object,the use of fungicides,disinfectants.Kill microorganisms and remove mold spots.
Physical cleaning and chemical cleaning have their own advantages and disadvantages,and complement each other well.In the practical application process,they are usually used together to obtain better cleaning results.
According to the different cleaning media,can be divided into wet cleaning and dry cleaning;usually,cleaning in liquid media is called wet cleaning.Cleaning in a gaseous medium is called dry cleaning.
Most of the traditional cleaning methods are wet cleaning and dry cleaning,which is easier to understand and a vacuum cleaner.However,in recent years,dry cleaning has been rapidly developed,such as laser cleaning,ultraviolet cleaning,
plasma cleaning,dry ice cleaning,etc.,which have been rapidly developed in the field of high,fine and sharp industrial technology.
In recent years,new technologies have also been used in cleaning technology.With the development of biotechnology,more and more enzymes and microorganisms are used in cleaning technology.This is the use of biochemical reactions;in air purification and water.
The use of activated carbon has also become increasingly popular in the use of adsorption.There is also electrolytic cleaning,etc.Thus,cleaning is simply divided into several categories.It is not possible to fully cover the current situation of the rapid development of cleaning technology.
