Qingyuan Automotive Repair Paint: Tell You Key Points of 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 power.
2. 50% to 60% of the coating power means that the remaining 40% to 50% of the overspray coating must be captured and processed before being emitted into 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 power 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. Using less power to solidify the paint film on the exterior of the vehicle body to obtain high-quality coating products is another important topic, known as 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. Another important issue is to recover or recycle the components of paint waste and dispose of waste residue appropriately, which is called 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 to human health has been discussed recently. Among these emissions, some 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 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 methods to complete these policies is attributed to the issue of appearance monitoring.
