Pretreatment heat exchanger,pretreatment equipment
Description
The pretreatment equipment mainly uses the physical mechanical scouring and chemical reaction principle to process the workpiece; the workpiece suspended on the logistics conveying line sequentially enters the pre-treatment equipment shed, and the corresponding processing liquid is pumped in the pump Under the action of suction, spray pipe distribution and nozzle atomization, it is evenly sprayed on the surface of the workpiece according to a certain pressure, flow and temperature. The grease, scale, dust and debris on the surface of the workpiece are cleaned; then the substrate and treatment are processed. The bath chemically reacts to provide an excellent corrosion-resistant substrate for the final coating of the workpiece.
Structural
The pretreatment equipment mainly consists of various process tanks, tank liquid mixing system, tank liquid heating system, phosphating slag removal system, ventilation system, water supply and drainage pipeline system and logistics transportation system.
The pretreatment equipment has different main structure forms: impregnated type and tunnel through spray type; the impregnated type is suitable for production lines with large output and stupid parts, etc.; Through the spray type, it is suitable for small workpieces and has a large production line.
