2. Precision Industrial Cleaning Market Analysis

(1) Overview of market development

In many processing industries, some intermediate processes need to be cleaned first before the next process can be carried out, and some of the final products need to be cleaned again. Such as metal, plastic parts and glass in electroplating, painting, vacuum coating before precision cleaning, in order to remove oil and dirt; textile industry in cotton, wool, silk, linen and other scouring cleaning; paper industry in degreasing, deinking cleaning. Precision industrial cleaning is directly related to product quality and performance, if the residual dirt is greater than the requirements, there will be bubbles, peeling, defects and other problems, generally need special cleaning equipment and process. There are certain requirements for the purity of the cleaning agent, the water must be purified, and some of the working environment requires a clean room. Because the cleaning technology and equipment used in the production process of different industries and products are very different, even if the same products, enterprises of different sizes and different investment levels, the cleaning process and cleaning equipment are also different. The same metal parts processing enterprises, large investment may use fully automatic running water cleaning line, while small investment may use manual washing, first with diesel oil to remove oil and metal chips,

Reuse solvent deoiling and fine washing; Large-scale automatic cleaning and installation may require tens of millions of dollars or even hundreds of millions of dollars. However, enterprises with small investment may only spend tens of thousands of yuan to buy a single-tank or multi-tank cleaning machine, and some even have several pots and cans. The mainstream technology commonly used in the field of precision industrial cleaning is a combination of ultrasonic steam washing (heating) and spraying. Using water washing process, solvent recovery and regeneration stations need to be added to increase the drying process and the auxiliary pure water preparation and sewage treatment using solvent cleaning agents. Solvents with relatively low boiling points should also be condensed and sealed. Using solvents with high boiling points, drying equipment should be added; and the use of flash point of the solvent to increase the explosion-proof measures.

Such as metal, plastic parts and glass in electroplating, painting, vacuum coating before precision cleaning, in order to remove oil and dirt; textile industry in cotton, wool, silk, linen and other scouring cleaning; paper industry in degreasing, deinking cleaning.
(3) Technical requirements for cleaning

In recent years, some new cleaning technologies and equipment have been gradually developed and applied, such as vacuum cleaning, plasma cleaning, UV/odor hydrogen cleaning, laser cleaning, dry ice cleaning, etc., showing good results and application prospects. At the same time, with the improvement of the overall level of industry, cleaning-free technology has also begun to be promoted, especially in the fields of electronic industry and precision machining, clean packaging technology can make components and silicon wafers "out of the box". The development of solid flux has made the circuit board cleaning-free technology increasingly popular. Some precision metal processing uses no residue stamping or drawing oil, combined with the next blackening process, to directly heat and volatilize the processing oil, to achieve no cleaning, in the color picture tube shadow mask production process has been applied.
The cleaning equipment, cleaning agent and cleaning technology needed for precision industrial cleaning can now be basically based in China. Shenzhen United Environmental Protection Equipment Co., Ltd. and other professional cleaning equipment production units have won the bid in international public bidding for many times, and mass production of stand-alone automatic and complete sets of large-scale cleaning equipment, after acceptance by domestic and international experts, can fully meet the needs of China's cleaning industry.
(4) Future development prospects

Precision cleaning equipment as industrial production equipment, market development and industrial upgrading and transformation are inseparable. With the upgrading and transformation of China's industry, the current domestic precision cleaning equipment industry presents the following trends:
1) The scale of the industry continues to expand

With the gradual deepening of China's industrialization, the application field of precision cleaning equipment is becoming more and more extensive, and the corresponding industrial scale is also expanding. On the one hand, in recent years, the rise of flat panel display, semiconductor, photovoltaic and other high-tech industries, due to the high precision of the production process of its products, precision cleaning equipment is an indispensable production line equipment in its production process, which greatly broadens the market space of precision cleaning equipment. On the other hand, traditional manufacturing enterprises through the purchase of advanced automatic cleaning equipment to optimize the transformation of production lines, enhance the level of automation to improve production efficiency, improve product quality has become an inevitable trend; in general, with the continuous progress of industrial technology and the improvement of product processing precision, the application field of precision cleaning equipment will continue to expand.
2) Technical requirements are getting higher and higher

With the continuous expansion of application fields, customers have also put forward higher technical requirements for precision cleaning equipment, which not only requires the performance improvement of a single cleaning technology, but also requires the combination of a variety of cleaning technologies to improve cleaning efficiency and cleanliness. For example, spray technology widely used in auto parts, aerospace, hardware and other industries has been integrated into high-pressure gas spray. Due to the particularity of the products themselves, some fast-growing emerging scientific and technological fields have higher requirements for cleaning. For example, the cleaning of large-size panels requires a combination of rolling brushes, spraying and dipping, and the cleaning of semiconductor chips requires ultrasonic cleaning equipment to reach megabound. The continuous improvement of downstream customer requirements is both an opportunity and a challenge for precision cleaning equipment manufacturers.

Manufacturers with the pace of industrial upgrading will stand out and become industry leaders.

3) Green environmental protection

Precision cleaning is one of the main links of resource consumption and pollutant emission in industrial production. With the gradual strengthening of the Chinese government's efforts to promote cleaner production, enterprise energy prices and sewage costs gradually increase, downstream industries put forward higher requirements for environmental protection and energy conservation of precision cleaning equipment, such as the use of hydrocarbons instead of ODS, the recycling of cleaning media and post-processing.
