Qhov tshwm sim ntawm corrosion puas nyob rau hauv stainless hlau kav yuav roughly muab faib ua ob pawg: general corrosion thiab hauv zos corrosion. Corrosion feem ntau yog hais txog kev xeb uas sib npaug lossis tsis sib npaug ntawm tag nrho cov khoom ntawm cov khoom. Hnub no, lubstainless hlau yeeb nkab manufacturersyuav txheeb nws rau koj.
Vim li cas stainless hlau welded yeeb nkab undergo nto corrosion?
1. Plua plav
Feem ntau thaum stainless hlau welded kav yog ua tiav, yuav muaj ib co hmoov av nyob ib ncig ntawm lawv, thiab cov plua plav nyob rau hauv lub ambient cua yuav poob rau saum npoo ntawm stainless hlau welded kav. Cov plua plav no tuaj yeem ntxuav nrog dej lossis tshuaj alkaline. Txawm li cas los xij, yog tias cov av nplaum nplaum, nws yuav tsum tau ntxuav nrog rab phom dej siab. Yog tias tsis tau ntxuav hauv lub sijhawm, nws yuav ua rau lub ntsej muag corrosion ntawm stainless hlau welded kav.
2. Floating hlau hmoov los yog embedded
Ntawmnto ntawm stainless hlau welded kav, dawb hlau yuav ua rau nto xeb thiab corrosion. Yog li nws yuav tsum tau muab tshem tawm. Floating hlau feem ntau yuav raug tshem tawm nrog rau cov plua plav. Qee qhov chaw uas muaj zog adhesion yuav tsum tau kho raws li cov hlau embedded.
Ntxiv nrog rau cov plua plav, muaj ntau qhov chaw ntawm cov hlau saum npoo, nrog rau kev ntxuav nrog cov pa roj carbon zoo tib yam hlau txhuam thiab tua blasting nrog xuab zeb, iav hlaws lossis lwm yam abrasives yav tas los siv rau cov pa roj carbon zoo tib yam, cov hlau tsis tshua muaj hlau lossis hlau castings, lossis sib tsoo yav dhau los hais txog cov khoom tsis-stainless hlau ze ntawm stainless hlau qhov chaw thiab khoom siv. Yog tias tsis muaj kev tiv thaiv kev tiv thaiv los tiv thaiv cov yeeb nkab steel hlau thaum lub sijhawm tshem tawm lossis nqa cov txheej txheem, cov hlau ntawm cov hlua hlau, cov khoom sib kis, thiab cov chaw ua haujlwm tuaj yeem yooj yim ua rau hauv qhov chaw.
3. Kos
Txhawm rau tiv thaiv kev tsim cov txheej txheem lubricants lossis cov khoom siv lossis cov av, nco ntsoov ua kom huv thiab du du nto xws li khawb ntawm cov kav hlau stainless.
4. Thermal tempering xim thiab lwm yam oxide txheej
Thaum lub sij hawm vuam los yog sib tsoo txheej txheem, cov yeeb nkab steel hlau yuav raug rhuab mus rau ib qho kub ntawm cov huab cua. Lub sijhawm no, cov xim chromium oxide thermal tempering yuav tshwm rau ntawm ob sab ntawm cov vuam, qhov chaw qis, thiab hauv qab ntawm qhov vuam. Cov xim thermal tempering yog nyias dua li oxidation tiv thaiv zaj duab xis thiab pom. Cov xim, nyob ntawm qhov tuab, tuaj yeem muaj los ntawm iridescent, xiav, thiab ntshav mus rau daj ntseg daj thiab xim av. Thicker oxides feem ntau yog dub.
5. Qhov chaw xeb
Cov xeb qee zaum tshwm sim ntawm cov kav hlau tsis muaj steel lossis cov khoom siv, qhia tias muaj kab mob loj heev ntawm cov yeeb nkab nto. Cov xeb yuav tsum tau muab tshem tawm ua ntej cov cuab yeej muab tso rau hauv kev pabcuam, thiab cov chaw huv huv huv yuav tsum tau kuaj xyuas los ntawm kev ntsuas hlau thiab / lossis kev kuaj dej.
Cov saum toj no yog cov yam ntxwv thiab kev tiv thaiv kev tiv thaiv raucorrosion ntawm stainless hlau welded kav. Kuv vam tias kev sib koom ntawm stainless hlau yeeb nkab manufacturers tuaj yeem pab txhua tus.
