Huicong Coatings Network News: Modern coating lines can well meet production requirements, regardless of air, humidity and temperature. However, the traditional coating line does not guarantee the requirements of air, humidity and temperature. As a result, the paint film is prone to problems such as vacuum, particles and peeling, which cannot guarantee the effective control of air dust and seriously affects 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, the cleaning process and the grinding process, so as to prevent the grinding dust from entering the drying furnace and the spraying room, and reduce the adverse effects of the grinding dust on the spraying production. In addition, but also with environmental protection equipment protection coating environmental protection. In recent years, under the guidance of domestic policies, powder coatings, high-solid coatings and water-based coatings have developed rapidly, and the application of these coatings in different production lines will have relatively large differences in results.

The pollution source of the coating line

will cause noise, waste residue, waste water and waste gas during the coating. The exhaust gas of the coating production line comes from the drying furnace, the drying room and the air jet room. Pollutants generally include photochemical smog solvents, odorous coatings, decomposition reaction products and spray paint dust. Applying coatings with low or no organic solvents is a simple way to address organic contamination.

Environmental Protection Coating Equipment

EDRO Reverse Osmosis Equipment

This device uses the principle of membrane permeation to complete medium separation. This device has been well applied in the domestic beverage, pharmaceutical, chemical, electronics and power industries. This technology is gradually replacing the traditional ion exchange process to make pure water. Generally speaking, the desalination rate of the water after the treatment of the device can reach the level of 97% to 98%, and it is very stable.

Pretreatment Ceramic Conversion Film Equipment

The film of this equipment is formed after the production of zirconium oxide, titanium oxide and aluminum oxide in a special process. Under pressure, the raw materials will flow in the tube, where large molecules will be intercepted by the membrane, while small molecules can smoothly pass through the membrane. This process achieves the purpose of fluid purification, concentration and separation. This kind of membrane has the advantages of long service life, good separation performance, narrow pore size distribution, strong cleanability, large permeability, high mechanical strength, chemical corrosion resistance and high temperature resistance. It has been successfully applied in automobile coating, medicine, biology, food, petrochemical and other fields.

Wastewater Treatment Ultrafiltration Equipment

This device applies membrane separation technology. Compared with traditional water treatment methods, this treatment method has more outstanding effects and has the advantages of recovering useful substances and fully circulating wastewater. 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, for the needs of environmental protection and high efficiency, the automotive coating industry is also applying this technology in the process of dealing with waste paint. The advantages of convenient operation, simple operation, energy saving and high separation efficiency of membrane filtration technology endow the technology with great potential for wastewater treatment. Industrial wastewater mostly contains oil, alkali and acid and other substances, has a relatively harsh treatment environment. Therefore, wastewater treatment membranes must have outstanding performance, achieve long-term treatment and maintain efficient treatment. According to this requirement, the filter membrane with outstanding performance and strong anti-pollution level is the development trend of the technology and device in the future. In addition, the research on engineering supporting pretreatment, membrane fouling control, membrane fouling model and membrane fouling mechanism will also be the research direction of this technology in the future.

Water-based coating equipment

In the production and construction, water-based coating is a material that uses water as a solvent, and water-based coating devices can be cleaned with water. The solid content of this material is generally high and the price is relatively low. The coating process and coating parameters need to 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 in construction. Secondly, the low toxicity of the water-based coating itself can improve the working environment and reduce the pollution of the atmospheric environment. * After the water-based coating in humid environment, wet environment can be directly applied, adaptability is relatively strong, has a good coating adhesion, the tools used can be directly used to clean water, reducing the consumption of cleaning solvent. In today's increasingly strong environmental awareness, the application of environmental protection equipment has become the direction and trend of social development. Improving the effectiveness of painting, reducing the cost of painting production and reducing the harm caused by painting are the primary issues in the painting industry. Because of the environmental protection coating equipment has a huge development value, so it will get the extensive attention of the coating industry.
