Qingyuan Automotive Repair Paint Manufacturer Tells You Six Important Issues in Automotive Spray System
1. The painting system can be envisioned as starting from the spray gun spraying paint onto the exterior of the vehicle. After the paint is atomized by the spray gun, only a portion of the paint is actually applied to the exterior of the vehicle. The ratio of the amount of paint applied to the exterior of the vehicle to the total amount sprayed by the spray gun is defined as the coating efficiency.
2. The efficiency of 50-60 coating means that the remaining 40-50 overspray coating must be captured and processed before being emitted to the external environment. Due to the use of many 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 efficiency of overspray paint.
3. After the car body is sprayed, the wet film on the exterior 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. Consuming less power to solidify the paint film on the exterior of the vehicle body to obtain high-quality coating products 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 treatment will be collected and processed, and some of the coating and purified water components will be recovered and recycled. The rest will be treated as waste residue. Recycling or recycling the components of paint waste as much as possible with good usage costs 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 harm of VOC in coatings to human health has recently been discussed. Some of these emissions can be classified as greenhouse gases that affect global warming. Controlling and reducing the generation of greenhouse gases and effectively oxidizing VOC released is another important topic, known as VOC and greenhouse gas emissions.
6. In order to ensure that the final product meets or exceeds the requirements of the car manufacturer and meets customer expectations, it is necessary to continuously monitor the quality of the coating. Finding suitable ways to complete these policies is a matter of external appearance monitoring.
