Txawm li cas los xij, ib lo lus nug uas feem ntau tshwm sim yog "txawm tias cov hlau tsis muaj ntxeem tau". Cov lus teb raug yog, cov hlau tsis zoo ib txwm tsis ntxeem tau.
Hauv tsab ntawv blog no, peb yuav tshawb txog cov ntsiab lus ntawm porosity hauv stainless hlau thiab txiav txim siab seb nws puas yog cov khoom ntxeem tau.

1. Stainless hlau yog dab tsi?

Ua ntej, peb yuav tsum paub dab tsi yog stainless hlau?
Stainless hlau yog ib hom hlau uas muaj tsawg kawg yog 10.5% chromium. Lwm cov ntsiab lus, xws li npib tsib xee, molybdenum, thiab titanium, kuj tseem tuaj yeem raug ntxiv los txhim kho nws cov khoom tiv thaiv corrosion. Stainless hlau yog lub npe hu rau nws lub zog siab, durability, thiab tsis kam mus corrosion, ua rau nws zoo tagnrho rau siv nyob rau hauv hnyav ib puag ncig.

Tab sis nco ntsoov, Muaj ntau ntau hom stainless hlau, txhua tus nrog nws cov khoom tshwj xeeb thiab cov yam ntxwv. Xws li Austenitic stainless hlau, tsis yog-sib nqus thiab muaj kev tiv thaiv corrosion zoo heev, thaum ferritic stainless hlau yog hlau nplaum thiab tsawg dua corrosion-resistant.

2. Porosity nyob rau hauv cov ntaub ntawv

Tom qab ntawd peb yuav tsum paub tias Porosity yog dab tsi.
Nyob rau hauv luv luv, Porosity yog qhov muaj qhov tsis muaj chaw lossis qhov pores hauv cov khoom. Cov ntaub ntawv ntxeem tau muaj peev xwm nqus tau cov kua thiab cov pa roj, uas tuaj yeem cuam tshuam rau lawv cov khoom thiab kav ntev. Porosity tuaj yeem muaj nyob rau hauv qee cov ntaub ntawv, xws li ntoo lossis daim txhuam cev, lossis nws tuaj yeem yog los ntawm kev tsim khoom, xws li casting lossis vuam.

Lub xub ntiag ntawm porosity tuaj yeem cuam tshuam rau lub zog ntawm cov khoom siv, xws li lub zog, ductility, thiab toughness. Cov ntaub ntawv ntxeem tau kuj yuav ua rau corrosion ntau dua, vim tias muaj cov voids tuaj yeem tsim txoj hauv kev rau corrosive agents nkag mus rau cov khoom.

3. Porosity nyob rau hauv Stainless hlau

Stainless hlau tuaj yeem ua ntxeem tau vim muaj ntau yam, suav nrog cov txheej txheem tsim khoom tsis zoo, raug corrosive ib puag ncig, thiab muaj cov impurities. Feem ntau hom porosity nyob rau hauv stainless hlau yog intergranular porosity, uas yog tshwm sim los ntawm nag lossis daus ntawm carbides ntawm grain ciam teb thaum vuam.

Intergranular porosity tuaj yeem txo qhov corrosion kuj ntawm stainless hlau thiab cuam tshuam rau nws cov khoom siv kho tshuab. Lwm hom porosity uas yuav tshwm sim hauv stainless hlau muaj xws li hydrogen-induced porosity thiab dendritic segregation.

4. Kev ntsuam xyuas qhov porosity hauv Stainless hlau

Muaj ob peb txoj hauv kev los ntsuas qhov porosity ntawm stainless hlau, suav nrog kev tshuaj xyuas qhov muag, kev ntsuas dej nkag mus, thiab X-ray radiography. Kev tshuaj xyuas qhov muag pom pom qhov muag ntawm cov khoom siv rau cov cim qhia ntawm porosity, xws li voids lossis tawg. Kev ntsuam xyuas kua dej yog siv cov tshuaj penetrant rau saum npoo ntawm cov khoom thiab tom qab ntawd siv tus tsim tawm los qhia txog qhov tsis xws luag.

X-ray radiography yog ib txoj kev kuaj tsis muaj kev puas tsuaj uas siv X-rays los tsim cov duab ntawm cov qauv sab hauv ntawm cov khoom. Txoj kev no yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev txheeb xyuas qhov porosity uas yuav muaj nyob hauv qab ntawm cov khoom siv.

5. Daim ntawv thov ntawm Cov Hlau Stainless

Cov hlau tsis ntxeem tau yog qhov tseem ceeb hauv ntau qhov kev lag luam, suav nrog kev ua zaub mov, tshuaj, thiab khoom siv kho mob. Qhov tsis muaj qhov ntxeem tau ntawm cov hlau tsis huv ua rau nws yooj yim los ntxuav thiab ntxuav, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv ib puag ncig uas kev nyiam huv yog qhov tseem ceeb.

Stainless hlau kuj tseem siv rau hauv kev tsim kho cov tshuaj thiab petrochemical cov nroj tsuag, qhov twg nws raug rau hnyav corrosive ib puag ncig. Tsis yog-porous stainless hlau yog tsim nyog nyob rau hauv cov ntaub ntawv no los xyuas kom meej tias cov khoom yog resistant rau corrosion thiab tuaj yeem tiv taus qhov hnyav.

Xaus

Hauv kev xaus, stainless hlau tuaj yeem dhau los ua ntxeem tau vim muaj ntau yam, suav nrog cov txheej txheem tsim khoom tsis zoo, cuam tshuam rau ib puag ncig corrosive, thiab muaj cov impurities. Porosity nyob rau hauv stainless hlau tuaj yeem txo nws cov corrosion kuj thiab cuam tshuam rau nws cov khoom siv kho tshuab.
