Qhov saum npoo tiav ntawm high-purity stainless hlau piping tshuab ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb ua khoom noj thiab tshuaj. Zoo nto tiav tau ntxhua, txo cov microbial kev loj hlob, kev txhim kho corrosion, thiab tshem tawm cov hlau tsis zoo. Txhawm rau txhawm rau txhim kho saum npoo zoo ntawm cov hlau tsis xeb hlau cov yeeb nkab, uas yog, txhawm rau txhim kho cov txheej txheem saum npoo thiab cov qauv morphological, thiab txo cov naj npawb ntawm cov khaubncaws sab nraud povtseg, cov txheej txheem kev kho saum npoo yog raws li hauv qab no:
1. Mechanical sib tsoo thiab polishing (Mechanically Polished) hu ua MP
Kev sib tsoo kom zoo ntawm lub ntsej muag kom txhim kho saum npoo tawv tuaj yeem txhim kho qhov kev ntxhib los mos saum npoo yam tsis muaj kev txhim kho morphological qauv, qib zog, thiab cov lej ntawm txheej txheej.
2. Buffed Polished (Buffed Polished) hu ua BP
Txoj hauv kev siv ntau hauv kev lag luam stainless hlau kom muaj qhov ci ci ntawm qhov chaw, txawm hais tias Ra tus nqi yuav zoo heev, ntau cov kab nrib pleb tuaj yeem pom nyob rau hauv lub tshuab hluav taws xob, qhov tseeb hauv thaj chaw yog nthuav dav, thiab cov sib cais ferrite thiab martensite qauv nyob hauv zos. Qhov saum npoo yog paug nrog ntau impurities li zoo li pob zeb tawg.
Vim tias siv cov ntawv polishing siv, ntau cov hmoov tsis huv raug khaws cia hauv qhov tsis txaus siab thiab maj mam tso tawm rau hauv cov kua dej, ua kom cov zaub mov tsis huv.
3. Pickled or passivated (Pickled & Passivated / Chemically Polished) xa mus ua AP thiab CP
Cov yeeb nkab txhuam tau los yog hla dhau yam tsis muaj qhov ua kom zoo dua rau saum npoo, tab sis nws tshem tawm cov khoom seem ntawm lub ntsej muag thiab txo cov theem zog tsis txo cov txheej txheej. Kev tiv thaiv passivation txheej txheej ntawm chromium oxide yog tsim nyob rau saum npoo ntawm cov hlau thaiv los tiv thaiv cov hlau stainless los ntawm kev tiv thaiv oxidation.
4. Electro Polishing (Electro Polishing) hu ua EP
Los ntawm electrochemical polishing, cov nplaim deg thiab cov qauv tsim kho tau ua tau zoo heev, thiab qhov tseeb thaj tsam chaw tuaj yeem raug txo kom tsawg. Qhov saum npoo yog kaw, tuab chrome oxide zaj duab xis nrog lub zog ze rau qib ib txwm ntawm cov hlau loj thiab cov nqi ntawm cov xov xwm raug txo kom tsawg.
Txhawm rau kom ua tiav qhov kev xaiv hluav taws xob zoo kawg, kev siv tshuab polishing yuav tsum muaj abrasive polishing.
Nws yuav tsum raug sau tseg tias tus nqi qub Ra tsis sawv cev tib yam kev kho mob saum npoo av.
