1. Thov ntsuas qhov ncig sab nraud ntawm lub taub hau. Yog hais tias lub tog raj kheej tau ua tiav ua ntej, thov nug lub tuam txhab txog qhov loj ntawm kev txiav tawm sab nraud.
2. Thov faib qhov sib nrug sab nraud ntawm lub taub hau rau 4 qhov sib npaug, thiab khij lub tog raj kheej thiab taub hau.
3. Rau qhov muab tso rau qhov chaw vuam, qhov chaw txiav txim siab ntawm kev muab tso rau qhov chaw vuam yog xaiv los ntawm cov neeg siv khoom raws li txoj kab uas hla thiab tuab ntawm lub phaj.
4. Tom qab cov vuam tsoo ua tiav, ua vuam. Ua tib zoo saib xyuas kev tiv thaiv nyob rau saum npoo ntawm stainless hlau taub hau. Tom qab lub taub hau thiab lub tog raj kheej tau sib sau ua ke, ntxuav lub vuam seam, thaj tsam cuam tshuam tshav kub thiab cov vuam vias ib puag ncig, cov kev sib tsoo thiab cov paug tsis huv nyob rau lub sijhawm, thiab nqa tawm PT tshuaj ntsuam xyuas thiab nto pickling.
5. Tiv thaiv ua pob thiab khawb rau saum npoo ntawm stainless hlau taub hau.
6. Tiv thaiv kom ncaj qha rau carbon hlau thiab tsis txhob muaj cov hlau ion paug.
7. Tsis txhob tso' t ntim khoom hauv qhov chaw qhib cua, cia kom deb ntawm nag.
8. Zam kev sib dhos sib dhos vuam. Tus qauv tsim qauv yuav tsum tiv thaiv kev ntxhov siab ntau dhau.
9. Cov chloride ion ntsiab lus ntawm cov dej rau kev ntsuas hydrostatic yuav tsum tsis txhob muaj ntau dua 25mg / L, thiab nws yuav tsum tau qhuav hauv lub sijhawm tom qab ntsuas.
10. Stainless hlau pickling tsis tuaj yeem siv txo cov kua qaub xws li hydrochloric acid.
11. nruj me ntsis raws txoj kev tshaj tawm xov xwm sib piv hauv cov" Kev Muaj Peev Xwm Txoj Cai" ;. Nco tseg: Rau cov metastable austenitic stainless hlau hau xws li 0Cr18Ni9 thiab 304, nws yog ib qho yooj yim uas ua rau nto pitting corrosion vim kev tiv thaiv tsis zoo. Thaum superimposed nrog kev ua haujlwm ntxhov siab thiab vuam kev ntxhov siab, nws yuav ua rau kev nyuaj siab corrosion thiab intergranular xeb. Vim li no, cov neeg siv khoom tau thov kom them nyiaj tshwj xeeb rau kev tiv thaiv saum npoo ntawm hom hlau no.
Cov ntsiab lus kom nco ntsoov thaum lub taub hau siv:
1. Lub taub hau carbon carbon yuav tawg nyob rau hauv ib puag ncig ntawm nitrate, ammonia, alkaline sodium, thiab lwm yam. Thov qhia kom tshem tawm cov kev ntxhov siab thaum lub sijhawm txiav txim lub taub hau.
2. Austenitic stainless hlau yuav muaj kev nyuaj siab corrosion tawg hauv ib puag ncig tshwj xeeb nrog chloride ions. Thov xaiv cov khoom tsim nyog thaum tsim qauv.
3. Rau cov pa roj carbon steel ntim uas xav tau qhov kub-dip galvanizing lossis aluminizing, thov ua kev kho cua sov ua ntej kom tshem tawm cov kev ntxhov siab.
