粉體、液體涂裝線
一、粉體、液體涂裝線：
預處理設備主要分為物理式、化學式。
1.物理式：（1）出去附著于鋼板表面的雜質，用稀釋劑除去油脂等污垢。
（2）如果硫酸鹽或腐蝕性鹽類，應以清水洗凈，以壓縮空氣吹干。
（3）在鋼板預處理流水線上，一拋丸或噴砂除銹方法將氧化皮、鐵銹及其他雜質清除干凈，然后用真空吸塵器或經凈化器的壓縮空氣將剛才表面清除干凈。
2.化學式：浸漬式、噴射式、浸噴結合式、噴—浸—噴相結合式。主要由槽體、槽液加熱系統(tǒng)、通風系統(tǒng)、槽液攪拌系統(tǒng)、磷化除渣系統(tǒng)、油水分離系統(tǒng)等組成。其中，磷化除渣和油水分離裝置是關鍵系統(tǒng)，磷化除渣有沉降法、斜板沉淀法、袋式過濾法、板框壓濾機等常用方法。油水分離主要有：吸附法、超濾法、熱油分離法和離心法等。
重要關鍵詞：粉體、液體涂裝線
Powder, liquid coating line
A, powder, liquid coating line:
Pretreatment equipment is mainly divided into physical, chemical formula.
1. Physical type: (1) go out on the surface of the adherent Yu Gangban impurities, use thinner to remove oil and dirt.
(2) if the sulfate or corrosive salts, should rinse, blow dry with compressed air.
(3) on the steel pretreatment line, a shot or sandblasting derusting method will scale, rust and other impurities removed, and then use a vacuum cleaner or by compressed air purifier will just surface clean.
2. The chemical formula: dip type, injection, combined type, combination type spray, dip, spray. Mainly by the bath tub, bath heating system, ventilation system, mixing system, phosphate slag system, oil water separation system, etc. Among them, phosphate slag and oil-water separation device is the key system, phosphate slag have settlement, of inclined plate precipitation, bag filter, commonly used methods, such as plate and frame filter press. Oil-water separation mainly include: adsorption method, ultrafiltration method, hot oil separation and centrifugation.
