Reducing Foreign Dependence: Status and Prospects of China's Cleaning Industry

Cleaning is a kind of labor closely related to people's life practice, and human beings have been engaged in this kind of labor since ancient times. Traditional cleaning has not attracted much attention because it is simple to operate, or is only attached to the production process as a process. Entering the 21st century, people's life has entered a comfortable era from the stage of subsistence and clothing. The increasing demand for cleaning products has accelerated the pace of new product research and development; at the same time, the rapid development of the manufacturing industry has also promoted companies such as cleaning equipment and cleaning agents. of rapid progress. The huge market demand in the two major cleaning fields of civil and industrial has created a new future for China's cleaning industry.

what is cleaning

Cleaning can be classified from different angles. According to the different cleaning scope, cleaning is usually divided into two categories: civil cleaning and industrial cleaning:

 

1. Civil cleaning

In daily life, washing closely related to personal and family life, including clothing washing, human skin, hair washing, household items, house cleaning, etc., is usually called civil washing.

2. Industrial cleaning

Cleaning involved in the labor process of industrial production belongs to the category of industrial cleaning. food industry. textile industry. paper industry. Printing industry. Petroleum processing industry. Transportation industry, electric power industry, metal processing industry, machinery industry. Automobile manufacturing, instrumentation, electronics industry, post and telecommunications, household appliances. Medical equipment. Optical products, military equipment, aerospace, atomic energy industry, etc. are widely used in cleaning technology.

 

Industrial cleaning can generally be classified in the following three ways:

According to the requirements of cleaning accuracy, it is mainly divided into three categories: general industrial cleaning, precision industrial cleaning and ultra-precision industrial cleaning.

General industrial cleaning includes the cleaning of the surfaces of vehicles, ships and airplanes, generally only coarse dirt can be removed;

Precision industrial cleaning includes cleaning in the processing and production of various products, cleaning of various materials and equipment surfaces, etc., which is characterized by the ability to remove tiny dirt particles;

Ultra-precision cleaning includes ultra-precision cleaning of mechanical parts, electronic components, optical components, etc. in the process of precision industrial production, with the purpose of removing extremely small dirt particles.

According to different cleaning methods, it can also be divided into physical cleaning and chemical cleaning: using the principles of mechanics, acoustics, optics, electricity, and heat, and relying on the action of external energy, such as mechanical friction, ultrasonic waves, negative pressure, and high pressure. ) hit. The method of removing dirt on the surface of objects such as ultraviolet rays and steam is called physical cleaning; the method of using chemicals or other solvents to remove dirt on the surface of objects by the action of chemical reactions is called chemical cleaning. For example, use various inorganic or organic acids to remove rust and scale on the surface of objects, use oxidants to remove stains on the surface of objects, and use fungicides. Disinfectants kill microorganisms and remove mildew, etc. Both physical cleaning and chemical cleaning have their own advantages and disadvantages, but also have good complementarity. In the actual application process, the two are usually used in combination to obtain better cleaning effect.

 

Current Situation of China's Cleaning Industry

Cleaning, as a basic activity in people's daily life, is so common that no one pays attention to it. Before the 1980s, the concept of cleaning industry did not appear in my country. However, in recent years, with the rapid economic development and the improvement of people's living standards. Cleaning is also attracting more and more attention. On the one hand, after the 1990s, with economic development and social progress, the scope of cleaning activities has gradually expanded, and a large number of professional cleaning companies have emerged. Especially in recent years. A large number of laid-off personnel participate in activities in this field, and various cleaning companies spread all over the country. They are usually engaged in both general industrial cleaning and civil cleaning. According to incomplete statistics, currently. There are more than 2,000 various cleaning companies in the country, with more than 300,000 employees.

On the other hand, new factories and production lines are being built everywhere in our country. Is gradually becoming a "world processing factory." Huge market demand. It provides a good opportunity for rapid development for industrial cleaning equipment manufacturers and professional cleaning agent production suppliers.

Currently. There are more than 1,000 manufacturing and operating enterprises of various cleaning equipment. Among them, ultrasonic cleaning machine manufacturers have grown from a few in the early 1990s to more than 200 now; there are also more than 1,000 cleaning agent production and distribution enterprises. formed a huge industry

The concept of cleaning industry first appeared in 1992 by the former State Environmental Protection Administration (now the State Environmental Protection Administration) organized by Peking University and other units. And approved by the State Council <China's national plan for the phase-out of ozone-depleting substances). According to the division of labor of the State Council. The cleaning industry is in charge of the former Ministry of Electronics Industry (now Ministry of Information Industry). Since 1992. Some are engaged in cleaning equipment. Cleaning agents, enterprises, institutions and individuals engaged in the production, application and research of cleaning technology have initiated preparations for the establishment of a national cleaning industry organization. On May 17, 1994, China Cleaning Engineering Technology Cooperation Association was officially approved by the state and registered with the Ministry of Civil Affairs.

In the past nine years, my country's cleaning industry has undergone earth-shaking changes. The member units of the Cleaning Association have also developed from the original precision industrial cleaning field to the national civil cleaning and industrial cleaning fields. Some international well-known enterprises have also taken the initiative to apply to join the China Association of Cleaning Engineering and Technology Cooperation. Currently. The Cleaning Association is the only national first-level industry association in China's cleaning industry. Has a wide range of representation.
