Stainless hlau yog cov khoom siv nrov tshaj plaws los ua cov thawv thiab cov khoom siv uas tuaj yeem tiv nrog cov khoom noj. Stainless hlau muaj cov khoom zoo tiv thaiv corrosion, durability thiab tsis muaj qhov hnyav. Txawm li cas los xij, nws yuav tsum tau nco ntsoov tias cov khoom siv no tsis yog ib txwm tiv taus qhov chaw nruj heev; nyob rau hauv rooj plaub no, cov khoom noj tshwj xeeb-qib formulations raug siv.

Tau kawg, nws yog qhov zoo tshaj plaws los khaws cov zaub mov hauv cov thawv hlau lossis iav, txij li cov khoom siv niaj hnub no nrov tsis tau raws li txhua qhov tsim nyog. Tsis tas li ntawd, nws txoj kev pab cuam lub neej luv dua li cov khoom ua los ntawm steel.

Ntau tus xav paub yuav ua li cas paub qhov txawv ntawm cov zaub mov qib stainless hlau los ntawm cov khoom tsis tsim nyog rau kev khaws khoom noj? Txhawm rau teb cov lus nug no, nws tsim nyog xav txog qhov zoo, nta thiab kev faib tawm ntawm cov hlau no.

Khoom noj khoom haus qib stainless hlau zoo

Yog tias peb tham txog qhov zoo ntawm cov khoom noj stainless hlau, ces nws tsim nyog qhia:

• kev nyab xeeb ntawm cov khoom;
• kev kho yooj yim;
• khoom tsis kam rau cov tshuaj feem ntau;
• hnav resistant;
• Tau ntsib cov kev cai hnyav hlau tawg.

Ntxiv rau, nws tau ntev tau ua pov thawj tias es tsis txhob siv cov lauj kaub uas tsis yog-stick txheej nws muaj txiaj ntsig zoo dua los siv cov tais diav ua los ntawm cov zaub mov qib stainless hlau. Cov khoom siv tib yam yog siv los ua cov qhov zoo tshaj plaws thiab qhov chaw tub yees.

Yuav ua li cas stainless hlau suav tias yog qib zaub mov

Stainless hlau tsim nyog rau kev cia khoom noj thiab kev npaj yog cov hlau alloyed uas muaj 25% chromium. Nws yog ua tsaug rau cov tshuaj no uas alloys nto moo rau lawv cov yam ntxwv los tiv thaiv corrosion. Nyob rau hauv cov ntaub ntawv ntawm kev sib cuag nrog ib tug nruj ib puag ncig, ib tug tshwj xeeb tiv thaiv zaj duab xis yog tsim nyob rau hauv cov hlau nto. Ua tsaug rau cov txheej saum npoo no, cov hlau tsis xeb.

Ntxiv rau, titanium, molybdenum, npib tsib xee thiab lwm yam tshuaj lom neeg tau ntxiv rau cov zaub mov qib stainless hlau, ntxiv rau kev tiv thaiv corrosion ntawm cov khoom.

GOST thiab qib stainless hlau

Yog tias peb tham txog tsoomfwv cov qauv, ces lawv tsis sau cov cai cuam tshuam txog cov hlau tsis muaj steel. Tias yog vim li cas cov kws tshaj lij pom tias nws nyuaj los teb cov ntaub ntawv twg yog pom zoo kom siv hauv kev lag luam khoom noj. Nyob rau hauv lem, manufacturers ntawm no stainless hlau teb hais tias, tsis hais nws hom, nws yog haum rau cov khoom noj khoom haus.

Puas cov kev cai yeej tsis hais dab tsi txog zaub mov qib stainless hlau? GOST 5632-72 yog kab tias tus qauv ze tshaj plawsib daim ntawv uas tuaj yeem siv tau thaum xaiv cov hlau zoo tshaj plaws rau kev siv hauv tsev. Lub Xeev Tus Qauv no hais txog cov qib high-alloy steel thiab corrosion-resistant thiab kub-resistant alloys. Cia wb mus saib qhov kev faib tawm no.

Hauv Tebchaws Europe, cov hlau no yog tsim los ntawm lub npe AISI 430. Cov hlau tsis muaj stainless yog qhov tseem ceeb yog tias cov zaub mov hauv cov tais diav raug kev kho cua sov. Hom hlau no muaj lub zog siab tshaj plaws. Txawm li cas los xij, cov khoom no yog deformed sai heev nyob rau hauv ib puag ncig leej faj. Nyob rau tib lub sijhawm, stainless hlau tsis xeb thiab tuaj yeem tiv taus txhua yam kev ntxhov siab. Nws raug nquahu kom yuav cov lauj kaub kib los ntawm cov khoom siv no, vim 08X17 yog tus cwj pwm los ntawm cov coefficient siab ntawm thermal conductivity.

Txhua lwm yam khoom siv yog siv tshwj xeeb, lawv cov nqi ntau dua. Txawm li cas los xij, tsis yog tag nrho cov stainlesshlau tuaj yeem siv tau zoo rau kev ua noj thiab khaws cov zaub mov. Yuav kom tsis txhob delve rau hauv qhov sib txawv ntawm cov khoom noj stainless hlau thiab technical stainless hlau, nws yooj yim dua los nyeem ob peb cov lus pom zoo. Lawv yuav tso cai rau koj txiav txim siab sai sai seb cov khoom siv puas haum rau zaub mov. Qhov no muaj txiaj ntsig rau txhua tus neeg siv kev noj qab haus huv kom paub.

Yuav ua li cas kom paub qhov txawv ntawm cov khoom noj stainless hlau los ntawm kev?

Txhawm rau txiav txim siab txog cov ntsiab lus ntawm cov khoom tiv thaiv corrosion, nrog rau qhov ua tau ntawm nws txoj kev siv hauv lub neej txhua hnub, koj tuaj yeem sau tawm cov npe uas tau teev tseg saum toj no. Yog tias qhov cim no nyob ntawm cov tais diav, ces nws yog qhov tsim nyog rau kev ua noj thiab khaws cov zaub mov.

Tab sis qee zaum nws tshwm sim tias cov khoom siv ntawm lub npe tsis paub yog nyob rau hauv pem hauv ntej ntawm koj ob lub qhov muag, thiab tus neeg muag khoom hais tias cov hlau no yog ib puag ncig zoo thiab tsis tuaj yeem ua mob rau tib neeg. Hauv qhov no, nws txaus los tso cov hlau rau hauv 2% acetic tov thiab tos rau cov tshuaj tiv thaiv. Yog tias qhov ntxoov ntxoo ntawm cov khoom hloov pauv, nws tau dhau los ua tsaus, ces nws yog qhov zoo dua tsis siv nws. Qhov tsis sib xws ntawm cov xim qhia tias stainless hlau yog cov zaub mov tiag tiag. Nws tuaj yeem siv tau.

Muaj lwm txoj hauv kev uas cov neeg siv khoom feem ntau siv tom qab nyeem cov ntaub ntawv qhia txog kev txheeb xyuas cov zaub mov qib stainless hlau. Lawv siv cov hlau nplaum rau qhov no. Tab sis nws yuav tsum to taub tias txoj kev no tsis muaj txiaj ntsig, txij li cov hlau tsis muaj hlau tuaj yeem sib nqus thiab tsis sib nqus. Yog li ntawd, kev siv cov hlau nplaum yuav tsis pab txhua txoj hauv kev los txiav txim seb cov khoom puas tuaj yeem siv rau zaub mov.

Xaiv cov hlau zoo tshaj plaws, koj yuav tsum kawm cov ntaub ntawv khoom thiab nug tus neeg muag khoom rau cov ntaub ntawv txhawb nqa. Txhua yam khoom siv yuav tsum tau ua raws li cov qauv thiab cov kev cai. Yog tias tsis muaj qhov cim rau ntawm cov khoom, ces nws yog qhov zoo dua tsis kam txais cov khoom zoo li no. Txwv tsis pub, koj tuaj yeem yuav cov khoom siv uas tsis zoo thiab txaus ntshai rau tib neeg kev noj qab haus huv.
