Yog li hu ua pickling yog siv hydrofluoric acid thiab nitric acid tov los ntxuav steel nto oxide generated tom qab tshav kub-kho.Siv nyob rau hauv cov tshuaj muaj pes tsawg leeg thiab tus nqi piv: HF (3-8%), HNO3 (10-15%), H2O (tus nqi ntxiv) thaum ua cov tshuaj kub ntawm 40-60 ° C.

Steel yeeb nkab pickling txheej txheem:
Ntxuav cov khib nyiab hauv cov roj nchuav → Loaded baskets → Chemical degreasing → Hot water cleaning → Cold water cleaning → Chemical rust → high pressure hair pururge → Cov dej ntws los ntxuav → Cov dej kub ntxuav → Tshuab ziab → kuaj

Txoj kev pickling yuav tsum xyuam xim rau cov ntsiab lus hauv qab no:
Thawj point:qhov kev lees paub ntawm cov npe tuaj, specifications, kom muaj nuj nqis thiab straightening txiav zoo tsis tsim nyog lees txais ntawm ncua lub pickling thiab raws sij hawm daim ntawv ceeb toom ntawm lub zoo tswj department los yog rhiav.

Qhov thib ob point:Thawj yog ntxiv cov kua qaub raws li qhov sib piv tus nqi ntawm lub khw hauv pem teb tswj, ntxiv cov kua qaub yuav tsum muab sib npaug sib npaug hauv lub tank pickling, es tsis ntxiv rau hauv ib feem ntawm cov kua qaub tank;Tom qab ntawd tswj qhov luaj li cas ntawm qhov cub, txhawm rau tswj qhov kub ntawm cov kua qaub steel feem ntau tswj qhov kub ntawm cov kua qaub kom me ntsis steaming prevail (kwv yees li 60 degrees), thiab yuav tsum tsis txhob tswj qhov kub siab dhau los yog xav tias kub kub. kua qaub;seem yog los npaj cov txheej txheem ntawm qhov chaw steel yeeb nkab daim npav, kom paub qhov txawv ntawm tus lej sib txawv, Vim tias muaj ntau hom steel pickling lub sij hawm sib txawv.

Qhov thib peb point:cov txheej txheem pickling tswj, thiab tseem yog cov kauj ruam tseem ceeb tshaj plaws.Cov khoom sib txawv steel kav thiab tiav steel pickling thiab degreasing.Uas, lifting khoom steel kav yuav ncaj qha siv nylon hlua rau lub pickling tank, dai lub fashionable steel yeeb nkab yuav tsum tail siab lub taub hau qis, thiaj li hais tias cov kua qaub yuav ntse nkag mus rau hauv cov yeeb nkab bore;tiav steel yeeb nkab dai rau hauv cov kua qaub da dej pickling, thaum lub sij hawm tsim nyog nqa cov yeeb nkab steel rov qab rau hauv cov kua qaub tank, los ua cov oxidation ntawm cov yeeb nkab steel sab hauv thiab sab nraud Picchi no tawm kom tshem tawm cov yeeb nkab steel, maj mam branched substantial flush. Nrog cov dav hlau dej siab siab los ntxuav cov yeeb nkab bore, tom qab ntawd cov yeeb nkab steel rau hauv cov hlua khi rau hauv cov kua qaub kom tsim nyog lub sij hawm steel yeeb nkab dai tawm cov kua qaub tank yuav tsum tau soaked rau 10 feeb nyob rau hauv lub dab ntxuav tes thiab maj mam branched yaug sab hauv thiab sab nrauv. .Rau roj yeeb nkab yuav tsum mus sump tawm ntawm cov roj saum npoo thiab lubrication txiv qaub nyob rau hauv lub dab dej rau 10 feeb thiab ces yaug lub puab qhov-los ntawm-txoj hauj lwm flush;dov cov khoom tiav rau cov roj yeeb nkab hauv lub dab dej kom ntub dej rau lub sijhawm kom paub tseeb tias cov yeeb nkab steel tau txias tag, cov yeeb nkab steel rau hauv cov kua qaub da dej rau ib nrab feeb, thiab tom qab ntawd mus rau hauv lub dab dej thiab yaug-los ntawm ceg.

Qhov thib plaub point:cov txheej txheem pickling tom qab kev tshuaj xyuas ua haujlwm.Tiav tiav pickling steel yeeb nkab kuaj tsom feem ntau oxide huv ntawm sab hauv thiab sab nrauv ntawm cov yeeb nkab steel, tshwj xeeb tshaj yog nyob rau hauv kev huv ntawm lub puab tsaig, qhov zoo tshaj plaws siv xov paj DON los ntawm cov qauv tshuaj ntsuam xyuas, tus nqi piv txwv yuav tsum tsis pub tsawg tshaj 10%.Ua raws li acid blot kuaj cov hlau nto thiab steel yeeb nkab xim tshuaj ntsuam xyuas tsis ua hauj lwm yuav tsum tau re-pickling;deb cov roj ntawm cov yeeb nkab steel yuav tsum tsis muaj cov roj nchuav, tshwj xeeb yuav tsum tsis txhob muaj cov kua qaub tawm hauv cov yeeb nkab kawg.
