Current situation and market analysis of domestic industrial cleaning

I. Overview

Industrial cleaning industry is a new industry, in our country only 20 years of development history. After 20 years of rapid development, great progress has been made, and many practical problems in production practice have been successfully solved, which plays a great role in promoting the development of related industries, and becomes an important part of China's national economy to achieve sustainable development strategy. Compared with 20 years ago, industrial cleaning is no longer a simple labor, but a new industry that requires professional technology and professional equipment. The 21st century is an era of clean and environmental protection, and China's emerging cleaning industry will develop rapidly. Today, a variety of green, environmentally friendly cleaning technology continues to launch, new products and machinery and equipment continue to emerge, and the entire cleaning industry has penetrated into almost all industrial fields, the comprehensive progress of the cleaning industry has been and is becoming an indispensable driving force for the development of the national market economy, therefore, the cleaning industry is known as "sunrise industry" in our country.

Second, industrial cleaning technology and its application

From the principle of action, industrial cleaning technology generally includes chemical cleaning, physical cleaning and biological cleaning. The development process of these three cleaning technologies is described below.

1.1 Development process and status quo of chemical cleaning technology

1) Development process of chemical cleaning technology

The development of chemical cleaning technology is closely related to the progress of cleaning agents, and the progress of cleaning agents has experienced three stages of development: simple type, combined type, special convenient type. The cleaning agent used in the first stage is mainly hydrochloric acid, nitric acid, sulfuric acid, hydrofluoric acid, sodium hydroxide and other corrosive strong acids and bases. At that time, pickling corrosion inhibitors had few varieties and poor performance, and were only suitable for a certain acid and corrosion control of a certain metal material, and their corrosion inhibition performance was poor for a variety of metal materials and their components, which limited the application of chemical cleaning. The cleaning object is mainly the unit equipment related to heat transfer such as petroleum, chemical, electric power and heating. The oil remover is mainly solvent-based and two-phase emulsion, which is inflammable, explosive and toxic, and the waste liquid has serious pollution to the environment. At this stage, the composition of the cleaning agent is simple, the corrosion inhibition performance is poor, the comprehensive technical level is low, and it is easy to cause pickling corrosion accidents, organic solvent poisoning accidents and fire accidents due to wrong operation. The second stage is mainly a combined cleaning agent. With the emergence of Lan-826 multi-purpose pickling corrosion inhibitor as a sign, various functional cleaning additives such as penetrant, stripping agent, accelerator, catalyst, trivalent iron ion reducing agent and copper ion inhibitor have gradually entered the cleaning agent formula, so that the cleaning agent has stronger function, better synergic performance, scaling performance and corrosion inhibition effect. At this stage, chemical cleaning needs more theoretical knowledge of chemistry, materials science, metal corrosion science, material processing science and other disciplines, and the operation and control of cleaning needs more specialization. The third stage is marked by a large number of applications of simple special convenience cleaning agents, special dirt cleaning agents and low-dose non-stop cleaning agents. With the increasing improvement of cleaning agents, corrosion inhibitors and cleaning auxiliaries, a variety of safer and simpler special cleaning agents have emerged and been serialized, making cleaning agents more specialized, refined, efficient, safe and serialized, and forming a variety of special cleaning agent modules. At present, the domestic chemical cleaning technology is in the second stage, the third stage is beginning, the level of integration is low, and the development of functional cleaning agents has achieved some results.

2) Status of chemical cleaning technology

The development of chemical cleaning technology has made great progress and successfully solved many practical problems in production practice, but chemical cleaning is generally declining, and chemical cleaning currently accounts for more than 70% of the overall market share of industrial cleaning. In order to protect the natural environment, chemical cleaning technology will develop in the direction of environmental protection, functional, fine and integrated. With the progress of fine organic synthesis technology, biotechnology, detection technology and other related technologies, chemical cleaning technology has also been developed, and is developing in the direction of green environmental protection: the synthesis of green environmental protection chemical cleaning agents with biodegradation ability and enzyme catalysis; Weakly acidic or neutral organic compounds will replace strong acids and bases; Straight-chain organic compounds and plant extracts will replace the aromatic compounds. Phosphor and fluorine free cleaning agents will replace phosphor and fluorine containing cleaning agents; Water-based cleaning agents will replace solvent and emulsion cleaning agents; Biodegradable green environmental protection cleaning agent will replace the difficult to decompose polluting cleaning agent; All kinds of serialized "fool type" cleaning agent has strong function and easy operation.

1.2 Status of physical cleaning technology

Physical cleaning with a variety of mechanical external forces and energy to crush, decompose and peel away from the surface of the object, to achieve the effect of cleaning. In physical cleaning, water jet cleaning dominates and shows a rapid development trend, and pollution-free physical cleaning technologies such as PIG cleaning, dry ice cleaning, and ultrasonic cleaning are being rapidly promoted and applied.

Physical cleaning is the use of various forces, heat, sound, light, electricity and other physical effects to remove dirt, its technical level is mainly reflected in the equipment and its optimal configuration and comprehensive use. Physical cleaning does not need to consume a variety of raw materials, only need to consume a certain amount of energy, will not produce a variety of waste liquid pollution of the environment. At present, our country is in the second stage of the development of physical cleaning, high pressure water jet cleaning, PIG pipeline cleaning technology has been practical application, but in the integration of physical cleaning technology, domestic has just started, and there has been a great development abroad. In China, physical cleaning accounts for about 30% of the overall market share of industrial cleaning. Among them, high-pressure water jet cleaning occupies an absolutely dominant position, and high-pressure water jet cleaning accounts for 20% of the overall market share of industrial cleaning. Ultrasonic cleaning accounted for 5% of the overall market share of industrial cleaning; PIG cleaning accounted for 3% of the overall market share of industrial cleaning; Other physical cleaning technologies such as dry ice cleaning accounted for 2% of the overall market share for industrial cleaning.

1.3 Development process of biological cleaning technology

Biological cleaning is the process of using microorganisms to convert dirt such as oil attached to the surface of the equipment into non-toxic and harmless water-soluble substances. This kind of cleaning agent can completely decompose dirt such as oil and organic matter, which is a real environmentally friendly green cleaning technology. Microbial cleaning technology has been greatly developed in foreign countries and successfully applied in many fields, but in the domestic biological cleaning technology is still in the research and development stage.

Third, industrial cleaning hot market

3. 1 Electronic information field

In the development zones around the country, for a long time, the protagonist is definitely the electronic information industry. New projects and developments are heavy

Most of them are electronic products, and with the transfer of foreign enterprises to the domestic production and processing base, there will be a large number of electronic factories and production lines to build or expand, requiring a large number of cleaning equipment. The proportion of ultra-precision industrial cleaning equipment and high value-added equipment has gradually increased. The focus areas include: communications products, computers and components, semiconductors, liquid crystals and optoelectronics.

3. 2 Cars

The huge market demand has driven the rapid development of China's automobile industry, which is in sharp contrast to the depression in other parts of the world. Now car manufacturers all over the world are eager to set up factories in China. Some parts manufacturers have also entered the country in large numbers, wholly owned, joint venture factories. The production of automobiles and parts generally requires precision cleaning, which puts forward new requirements for cleaning technology and cleaning equipment.

3. 3 Medical devices

Medical instruments such as syringes, surgical knives and so on in the production process not only to precision cleaning, but also through human experiments. The injection needle belongs to deep and fine air cleaning, which is very difficult, and is generally cleaned with freon. In the end, fluripleone is also used as a dispersant, and a layer of silicone oil is evenly covered on the surface of the needle to reduce the pain of the needle when it is pierced into the skin.

3. 4 Optics

Various optical products and components, such as camera lenses, large screen rear-projection TV lenses, slide projectors, projector lenses, etc., are still in strong demand, and these products have high requirements for cleaning equipment. The technology and equipment suitable for optical cleaning can be richly rewarded.

3. 5 Small Devices

China has a variety of enterprises with annual consumption of cleaning agents below 3 t, that is, small consumer users of cleaning agents are about 6 000 ~ 10 000. The characteristic of these enterprises is that there is generally no cleaning equipment, and many use freon hand washing or just simple equipment. Possible alternatives to cleaning agents are either too expensive to be acceptable; Or there are problems that require specialized equipment. The more feasible way is to use the current alternative cleaning agent to develop a "single-cylinder automatic" cleaning machine suitable for small users, which can adapt to the requirements of wide range, simple operation, less solvent consumption and low cost of use, and is easy for users to accept.

In the long run, the market capacity of industrial cleaning agents is huge. Now, from the breadth of the market point of view, cleaning has been widely recognized by the society, the service field has been from petroleum, chemical industry, energy, electricity to metallurgical construction, machinery and electronics, post and telecommunications, transportation, textile printing, nuclear industry, light industry and other social walks of life, from enterprises to families, large to complete sets of equipment, small to electronic parts need cleaning services, but different industries The degree of attention to cleaning is different, the purpose of cleaning is different, and the degree of dependence on the cleaning industry is also different. Cleaning has also gradually spread from key industrial cities to small and medium-sized cities, and then form a trend of popularization to urban and rural areas, regionalization characteristics are becoming more and more obvious, cleaning industry has become a socialized service industry, marking the formation of a broad market atmosphere in our country.

Fourth, domestic industrial cleaning market status and analysis

1, at present, China's cleaning industry is still in the production stage and industrialization stage, in the technical level there is still a large room for improvement. Cleaning agent formula is relatively simple, corrosion inhibition technology, operating technology level is relatively backward, the quality of practitioners is generally low, physical cleaning original, cleaning industry to develop chemical cleaning, the overall cleaning level is low, far behind the developed countries cleaning capacity, far from meeting the needs of the domestic market.

2, according to the latest data statistical analysis shows that China's civil and industrial cleaning market demand of up to 300 billion per year. 300 billion mainly civilian cleaning for the vast majority, industrial cleaning can only account for about 10%, it is not difficult to calculate that the industrial cleaning market every year

Demand should be 30 billion, and the current domestic industrial cleaning agent market supply is less than 6 billion. During the "eleventh Five-Year Plan" period, China will complete the elimination of ODS (ozone depleting substances), prohibit the production and consumption of CFCs (CFCS commercially known as freon), so as to enter the use period of HCFCs (chlorofluorocarbons), and China will produce and supply HFCs(hydrofluorocarbons) for developed countries.

3, China's cleaning industry started late, although there is no shortage of international well-known enterprises such as blue star cleaning, but the overall strength is still relatively weak, there are more problems. Due to the current domestic cleaning industry there are multiple management, segmentation phenomenon, so industry protection, disorderly competition, engineering service quality uneven phenomenon everywhere, the entry threshold needs to be improved. This will continue.

4, because the industry has no entry threshold, so the cleaning industry is dominated by individual enterprises, accounting for nearly 60 to 70%, and a sharp rise in the trend, among these enterprises do not have the relevant standards issued by the cleaning and other departments, has been far from meeting the requirements of The Times. With the deterioration of the global environment, the development of new environmental protection, pollution-free, low-cost green cleaning technology has become the inevitable development trend and competitive conditions of the cleaning industry, and environmentally friendly cleaning technology needs to be developed. At present, the traditional cleaning method and the technology and equipment of professional cleaning large-scale projects coexist in our country, but it can disrupt the bidding of the project at an absolute low price. There are not many brand enterprises, and the industry standards are backward. It is understood that the current domestic industrial cleaning enterprises can refer to the implementation of standards are still in the 1980s and 1990s, the coexistence of the Ministry of Chemical Industry model period. Due to the huge domestic market, foreign cleaning industry manufacturers have entered the Chinese market landing, bringing sophisticated equipment, high-quality cleaners and advanced cleaning technology, traditional cleaning methods will gradually withdraw from the market competition.

5, in view of the current development status of cleaning technology, chemical cleaning can clean almost all equipment and dirt, and physical cleaning because of the limitations of cleaning equipment, can only clean storage tanks, pipelines, heat exchangers and other internal structure is relatively simple or small equipment. Therefore, chemical cleaning also occupies the mainstream position of industrial cleaning. However, with the progress of physical cleaning equipment and technology, as well as the pollution-free nature of physical cleaning, physical cleaning will gradually replace chemical cleaning.

6, in the future, as the industry gradually matures, the development of the cleaning industry is booming, the market is very optimistic. With the introduction of foreign advanced technology, the development of China's cleaning technology will be more rapid, popular, a large number of colleges and universities, research institutes, professional companies of scientific and technological personnel will join the cleaning technology research and development team, some of the existing industry technical problems have been solved, the overall technical level of the industry has been greatly improved, new technology, new products emerge in large numbers. A variety of novel cleaning equipment into the market and people's normal life, people will no longer just rely on experience to clean, the industry division of labor more professional, meticulous, industry standards and technical specifications will be promoted and popularized, industry management norms will be orderly. Chemical cleaning technology will gradually develop in the direction of refinement, functionalization and integration, and many functional simpleton special cleaning agent products have been formed. The prospect of cleaning industry is infinite.

Fifth, the current problems faced by the cleaning industry in China

1) Institutional obstacles

Due to the influence of China's traditional departmentalism, the non-standardized and non-professional cleaning teams scattered in various industries and departments protect the interests of the industry and the department, and the exclusion of professional cleaning teams from entering the industry and the department is prominent. It should be seen that the protection of this egoism is inconsistent with the trend of industrial division of labor and specialization, and the unfair competition in the cleaning market is bound to affect the growth of the professional cleaning team. The result is an artificial wall that limits the expansion of the cleaning field

Base.

2) Technical obstacles

Although China's cleaning industry has developed rapidly for more than a decade, some single cleaning technology has reached or even exceeded the international advanced level, cleaning methods are increasingly diverse, but at the same time, it should also be noted that there are not many professional cleaning equipment manufacturers, the type is relatively single, and some professional cleaning equipment needs to rely on imports. This makes the development of China's cleaning industry in the technical field subject to others, restricting the improvement and in-depth production technology, many monitoring, analysis, control instruments and equipment in the cleaning process urgently need to be localization.

3) Financial barriers

At present, a considerable number of cleaning enterprises in China are relying on their own strength to develop, the foundation is relatively weak, the limitation of funds makes many cleaning enterprises in technology research and development, market management and operation, the establishment of a standardized industry system, to achieve sustainable development and other aspects of insufficient investment, facing greater difficulties.

4) Environmental protection puts forward new requirements for the cleaning industry

With the deterioration of the global environment, people's environmental protection awareness gradually strengthened, the cleaning industry in the environmental requirements are also higher and higher, because China's cleaning industry is in the extensive stage of development, people's understanding of environmental protection has not yet improved to the due height, some early development of cleaning technology in environmental protection there are some defects, with the improvement of environmental protection requirements, As well as the establishment and improvement of environmental protection regulations, environmental protection issues have become an important issue to be solved urgently for the sustainable development of the cleaning industry, which requires us to strengthen the research on new cleaning technology, develop pollution-free green cleaning technology, to meet the requirements of modern society for cleaning.

6, the development trend of domestic industrial cleaning technology

The development of chemical cleaning technology has made great progress and successfully solved the production practice
