簡介
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.
結構
前處理設備主要由各工藝槽體、槽液攪拌系統、槽液加熱系統、磷化除渣系統、通風系統、給排水管路系統以及物流輸送系統等部分組成。
前處理設備根據工件形狀和生產量不同，主要結構形式有浸漬式、隧道通過噴淋式；浸漬式適用于大件、笨件等產量不太大的生產線；隧道通過噴淋式適用于小工件且產量較大的生產流水線；
