Muaj pes tsawg leeg thiab xaiv ntawm Degreasing Agents rau hluav taws xob cua sov Tube Electroplating
2.1 Muaj pes tsawg leeg ntawm degreasing tus neeg sawv cev
Ib tug raug steel phaj detergent mas muaj alkali, surfactant, chelating tus neeg saib xyuas, cosolvent, anti re nag lossis daus tus neeg saib xyuas, defoamer, thiab lwm yam.
Hauv cov tshuaj degreasing ib txwm muaj, surfactants yog cov organic tebchaw nrog cov qauv tshwj xeeb thiab cov khoom uas tuaj yeem hloov pauv qhov kev sib tshuam ntawm ob theem lossis qhov nro ntawm cov kua (feem ntau yog dej), thiab muaj emulsifying, ntub dej, foaming, thiab ntxuav cov teebmeem. Lawv txhua tus muaj cov yam ntxwv zoo sib xws: cov qauv molecular muaj ob pawg hydrophilic thiab hydrophobic. Daim duab schematic ntawm cov qauv surfactant yog qhia hauv daim duab 1.
Fluorine, carbon silicon, thiab lwm yam [3]. Cov pab pawg hydrophilic feem ntau yog anionic, cationic, non ionic, thiab amphoteric functional pawg, uas muaj hydrophilicity txaus los xyuas kom meej tias tag nrho cov surfactant yog soluble hauv dej thiab muaj qhov tsim nyog solubility.
2.2 Xaiv cov tshuaj degreasing
Lub substrate tuaj ntawm Meigang's tin plating chav tsev txais yuav cov txheej txheem ntub dej, yog li piv rau cov txheej txheem qhuav qhuav, yuav muaj cov roj lipids seem nyob rau saum npoo ntawm cov sawb hlau. Piv nrog rau cov txheej txheem degreasing uas twb muaj lawm thiab tu cov txheej txheem rau tin plating units, tus neeg sawv cev degreasing rau Meigang lub tshuab hluav taws xob tin plating chav tsev yuav tsum muaj peev xwm tshem tawm cov roj zaub lipid. Lub leveling kua siv nyob rau hauv lub leveling tshuab ntawm Meigang lub nruam annealing unit yog ib tug ntev carbon saw qauv. Nyob rau hauv teb rau cov yam ntxwv ntawm ntev carbon saw organic tebchaw, cov mis ntawm cov uas twb muaj lawm degreasing tus neeg sawv cev tau raug kho los txhim kho nws lub peev xwm los tshem tawm cov residual leveling kua nyob rau saum npoo ntawm lub substrate.
Los ntawm cov txiaj ntsig kev xav tau, LECO nrhiav pom cov txiaj ntsig ntawm lub substrate ntxuav nrog 338YZ yog qhov nruab nrab, thaum qhov kev txhim kho 338YZ qauv yog tsom rau kev tshem tawm cov kua dej seem, thiab cov ntsiab lus carbon ntawm cov substrate ntxuav nrog 338MG degreaser yog txo qis (saib Table 1 ), ua rau lub phaj ci ntsa iab.
