Qingyuan Automobile Repair Paint Manufacturer Tells You Six Important Issues in the Spray System
1. The painting system can be imagined as starting from the spray gun spraying paint onto the surface of the vehicle. After the paint is atomized by the spray gun, only a portion of the paint is actually applied to the surface of the vehicle. The ratio of the amount of paint applied to the surface of the vehicle to the total amount sprayed by the spray gun is defined as the coating power.
2. A power of 50-60 means that the remaining 40-50 overspray coatings must be captured and processed before being emitted into the external environment. Due to the use of a large amount of coatings, choosing a water treatment or wet purification system is a better capture method. The ratio of the amount of overspray material captured to the total amount of paint entering the capture system is defined as the capture power of overspray paint.
3. After the car body is sprayed, the wet film on the surface of the car body needs to be dried or solidified, and the drying process is usually carried out in an infrared or hot air convection drying room. Using less energy to solidify the paint film on the body surface to obtain the highest quality coating product is another important topic, called the drying rate of the coating surface, which is related to the environment and coating quality.
4. The paint residue generated by the spray capture system will be collected and processed, and some of the paint and purified water components will be recycled and reused. The rest will be treated as waste residue. Recycling or recycling the components of paint waste at the best possible cost and environmentally friendly disposal of waste residue is another important issue, known as the issue of waste paint treatment and recycling.
5. During the spraying, wet mist removal, film solidification, and residue treatment and reuse processes, VOC and other gases that were originally dissolved in the circulating water of the coating and mist treatment will be released. These harmful gases to the environment need to be collected and oxidized before they can be discharged into the atmosphere. The damage of VOC to human health has been studied recently. Some of these emissions can be classified as greenhouse gases that affect global warming. Controlling and reducing the occurrence of greenhouse gases and effectively oxidizing the released VOC is another important topic, known as VOC and greenhouse gas emissions.
6. In order to ensure that the final product, a painted body, meets or exceeds the requirements of the car manufacturer and satisfies customer expectations, it is necessary to continuously monitor the quality of the coating. Finding suitable methods to complete these policies is a surface appearance monitoring issue.
