Spray pretreatment
1. More clean: nozzle cross arrangement, pump high level design, two fine filtration; at the same time control the cleaning time, liquid temperature, nozzle pressure angle, so that the workpiece cleaning cleaner
2. No liquid spilled and entering to other tanks: 20 years of field experience, continuous optimization and improvement of process
3. Saving labor: automated spray pretreatment, saving labor, saving costs.
Brief introduction
Spray pretreatment equipment mainly utilizes the principle of chemical reaction to treat workpieces. Hanging on the conveyor line of the workpiece in turn into the pre-treatment equipment shed body, the corresponding process of treatment fluid in the pump suction, spray pipeline distribution and nozzle atomization, according to a certain pressure, flow and temperature uniform spray on the surface of the workpiece, the surface of the workpiece oil, grease, oxidized skin, dust and sundries are cleaned; and then the substrate and the treatment of the tank liquid chemical reaction for the workpiece for the ultimate coating to provide excellent Anti-corrosive substrate base layer.
Structure
Pretreatment equipment mainly consists of process tanks, tank mixing system, tank heating system, phosphate slag removal system, ventilation system, water supply and drainage piping system, and logistics and transportation system.
Advantages:
1. Ensure that there is no problem of liquid spilling to other tanks: according to the distance of water mist splashing down under the maximum pressure of the pump and the time of water droplets coming down on the surface of the workpiece, to accurately design the filtration section of the workpiece, and reasonably arrange the extraction system.
2. Ensure that the workpiece is clean: can reasonably control the cleaning time, constant temperature degreasing liquid temperature and nozzle pressure and angle, so that the surface of the workpiece is cleaner.
3. Improve the quality and life of the workpiece: Adopt advanced degreasing and emulsion breaking technology to realize simultaneous processing and utilization, avoiding the secondary pollution of the workpiece. So that the products get better quality and prolong the service life of the products.
4. Labor saving: The line of pre-treatment can save 2-3 workers and labor cost.
5. Stable product quality: Automated operation, cleaner and more thorough cleaning, not affected by human factors.
Our Coating will design pre-treatment for you based on your spraying line and the actual situation of the workpiece. Pretreatment can be divided into online type and offline type, but online pretreatment is the development trend now. Its advantages lie in high automation, which can save workers and labor costs; and during use, it will not be affected by human factors and cleaned thoroughly to ensure stable product quality.
