Analysis on the application of environmental protection painting equipment

Modern coating line can well meet the production needs, whether it is air, humidity and temperature can meet the environmental protection production requirements. However, the traditional coating line can not guarantee the requirements of air, humidity and temperature, and the result is that the paint film is prone to vacuum, particles and peeling problems, which cannot guarantee the effective control of the amount of air dust, seriously affecting the atmospheric environment. In order to solve this problem, it is necessary to focus on the environmental problems of the production line, separate the painting process, cleaning process and grinding process, so as to avoid the grinding dust into the drying furnace and the spraying room, and reduce the adverse impact of grinding dust on the spraying production.

In addition, environmental protection equipment should be used to ensure the environmental protection of the coating. In recent years, under the guidance of domestic policies, powder coatings, high-solid coatings and water-based coatings have been rapidly developed, and the application of these coatings in different production lines will have relatively large differences in results.

There will be noise, waste residue, waste water and waste gas pollution in the painting. Among them, the exhaust gas of the painting production line comes from the drying furnace, the drying room and the jet room. The pollutants generally include photochemical aerosol solvents, malodorous coatings, decomposition products and spray paint dust. Applying coatings with low or no organic solvents is the easiest way to solve organic pollution.

This device uses the principle of thin film penetration to complete the separation of media. This device has been well used in domestic beverage, pharmaceutical, chemical, electronic and power industries. This technology is gradually replacing the traditional ion exchange process to produce pure water. Generally speaking, after the treatment of the device, the desalting rate of water can reach the level of 97% to 98%, and it is very stable.

The film of this equipment is formed after the production of zirconia, titanium oxide and alumina in a special process. Under pressure, the material will flow in the tube, where large molecules will be intercepted by the membrane, while small molecules can pass through the membrane smoothly. The process realizes the purpose of fluid purification, concentration and separation. This film has the advantages of long service life, good separation performance, narrow aperture distribution, strong washable, large penetration, high mechanical strength, chemical corrosion resistance and high temperature resistance, and has been successfully applied in automotive painting, medicine, biology, food and petrochemical fields.

The device uses membrane separation technology, which is more effective than traditional water treatment methods, and has the advantage of recovering useful substances and fully recycling waste water. The technology has the advantages of simple operation, low energy consumption and outstanding efficiency. This technology is often used in the treatment of oil wastewater and heavy metal wastewater, and is an important device in the food industry, textile printing and dyeing industry and paper industry. Of course, due to the need for environmental protection and efficiency, the automotive painting industry is also applying this technology in the process of treating waste paint.

Membrane filtration technology itself has the advantages of convenient operation, simple operation, outstanding energy saving and high separation efficiency, which gives the technology a great potential for wastewater treatment. Most of the industrial wastewater contains oil, alkali and acid and other substances, and has a relatively harsh treatment environment. Therefore, membranes for wastewater treatment must have outstanding properties, achieve long-term treatment and maintain efficient treatment. In view of this requirement, the filter membrane with excellent performance and strong anti-pollution level is the development trend of the technology and device in the future. In addition, the research of engineering supporting pretreatment, membrane pollution control, membrane pollution model and membrane pollution mechanism will also be the future research direction of this technology.

In the production and construction of water-based coating is a material that uses water as a solvent, and the water-based coating device can use water for cleaning. This material generally has a high solid content and a relatively low price. Coating process and coating parameters should meet the requirements of water-based coatings.

Compared with solvent coatings, the advantages of water-based coatings are as follows: first of all, it saves resources and can avoid fire during construction. Secondly, the low toxicity of water-based coatings can improve the working environment and reduce the pollution of the atmospheric environment. Water-based paint can be directly constructed in wet environment and wet environment, has strong adaptability, has good coating adhesion ability, and the tools used can be cleaned directly with water, reducing the consumption of cleaning solvents.

Today, with people's increasing awareness of environmental protection, the application of environmental protection painting equipment has become the direction and trend of social development. Improving the effectiveness of painting, reducing the production cost of painting and reducing the harm caused by painting are the primary topics of painting industry. Because of the great development value of environmental protection painting equipment, it will be widely concerned by the painting industry.
