Pickling:
Raws li ib tug tej yam concentration, kub thiab ceev, acids yog siv los tshem tawm cov hlau oxide daim tawv nqaij tshuaj, uas yog hu ua pickling.
Phosphating:
Cov txheej txheem ntawm kev tsim cov phosphate txheej ntawm cov hlau nto los ntawm cov tshuaj lom neeg thiab cov tshuaj electrochemical.Cov phosphate conversion zaj duab xis yog hu ua phosphating zaj duab xis.
Lub hom phiaj: txhawm rau txhim kho cov khoom tiv thaiv corrosion thiab tiv thaiv xeb ntawm qhov chaw ntawm cov khoom.Nyob rau tib lub sijhawm, phosphate zaj duab xis tsim los ua lub tshuab lubricating muaj cov tshuaj tiv thaiv zoo nrog cov roj nplua nyeem thiab txo qhov kev sib txhuam coefficient ntawm cov khoom siv tom ntej.Txhim kho xim adhesion thiab npaj rau cov kauj ruam tom ntej.
Saponification:
Tom qab lub workpiece yog phosphating, lub stearate thiab zinc phosphate zaj duab xis txheej nyob rau hauv cov kev daws rau immersed nyob rau hauv lub saponification da dej teb los tsim ib tug zinc stearate saponification txheej.Lub Hom Phiaj: Los tsim ib txheej saponification nrog zoo heev adsorption thiab lubrication ntawm cov khoom siv, thiaj li pab txhawb txoj kev vam meej ntawm kev ua haujlwm tom ntej.
Txoj kev pickling xeb thiab nplai yog txoj kev siv dav tshaj plaws hauv kev lag luam.Lub hom phiaj ntawm kev tshem tawm xeb thiab oxide nplai yog ua tiav los ntawm kev siv tshuab stripping nyhuv ntawm cov kua qaub ntawm oxide dissolution thiab corrosion los tsim hydrogen gas.Cov feem ntau siv nyob rau hauv pickling yog hydrochloric acid, sulfuric acid, thiab phosphoric acid.Nitric acid tsis tshua siv vim nws tsim cov pa roj nitrogen dioxide thaum lub sijhawm pickling.Hydrochloric acid pickling yog tsim rau siv nyob rau hauv qis kub, yuav tsum tsis txhob ntau tshaj 45 ℃, nws yuav tsum tau ntxiv ib tug tsim nyog tus nqi ntawm cov kua qaub pos inhibitor.Lub pickling ceev ntawm sulfuric acid nyob rau hauv qis kub yog qeeb heev, nws yog tsim nyog siv nyob rau hauv nruab nrab kub, kub 50 - 80 ℃, siv concentration ntawm 10% - 25%.Qhov zoo ntawm phosphoric acid pickling yog tias nws yuav tsis tsim cov corrosive residues, uas muaj kev nyab xeeb dua, tab sis qhov tsis zoo ntawm phosphoric acid yog tus nqi siab dua, qeeb qeeb pickling ceev, qhov kev siv dav dav yog 10% mus rau 40%, thiab kev ua haujlwm kub tuaj yeem ua tau. ib txwm kub rau 80 ℃.Hauv cov txheej txheem pickling, kev siv cov kua qaub sib xyaw kuj yog ib txoj hauv kev zoo heev, xws li hydrochloric acid-sulfuric acid mix acid, phosphoric acid-citric acid mix acid.
Cov kab pickling tsim los ntawm Wuxi T-tswj yog tag nrho nyob rau hauv thiab automated.Cov txheej txheem tsim khoom yog nqa tawm hauv lub tank kaw thiab cais tawm ntawm lub ntiaj teb sab nraud;cov kua qaub tsim tawm yog muab rho tawm los ntawm cov kua qaub pos huab rau kev kho kom huv;cov txheej txheem ntau lawm yog cais los ntawm kev noj qab haus huv ntawm tus neeg teb xov tooj Impact;tsis siv neeg tswj, siab ntau lawm efficiency, loj tso zis, tshwj xeeb tshaj yog haum rau loj tso zis, centralized ntau lawm;computer tsis siv neeg tswj cov txheej txheem tsis, ruaj khov txheej txheem;piv nrog rau yav dhau los pickling phosphating ntau lawm kab, zoo heev txhim kho kev ua tau zoo, tab sis kuj tsis tshua muaj neeg ntiaj teb txo cov pa phem rau ib puag ncig.
