Hauv kev lag luam niaj hnub no, cov khoom lag luam sau npe "316 stainless hlau" muaj ntau. Txawm li cas los xij, cov neeg siv khoom soj ntsuam feem ntau pom tias txawm tias tib lub "316" stamp, qee cov khoom muaj daim iav- zoo li ci rau lawv qhov chaw, thaum lwm tus muaj qhov qis - qhov tseem ceeb matte tiav; qee qhov nyob twj ywm zoo li tshiab tom qab siv ntau xyoo, thaum lwm tus tsim cov pob zeb los yog cov xim tsis zoo li ob peb lub hlis xwb. Tom qab qhov tsis sib xws hauv qhov tsos no yog kev sib ntaus sib tua uas muaj cov khoom sib xyaw, kev ua haujlwm, kev hloov pauv ib puag ncig, thiab kev ua lag luam ncaj ncees.
I.Component sib txawv: Ib qho yuam kev me me tuaj yeem ua rau muaj qhov yuam kev loj.
Cov tub ntxhais ntawm 316 stainless hlau nyob hauv nws cov tshuaj muaj pes tsawg leeg: 18% chromium, 10% npib tsib xee, thiab qhov tseem ceeb 2-3% molybdenum (Mo). Txawm li cas los xij, qhov kev hloov pauv me me hauv qhov muaj pes tsawg leeg yog thawj qhov teeb meem uas txiav txim siab nws lub neej zoo li qub.
Kev hloov pauv hauv cov ntsiab lus molybdenum:Molybdenum yog lub hauv paus tseem ceeb rau kev txhim kho pitting corrosion. Qee cov tuam ntxhab, hauv kev sib zog los txo cov nqi, tuaj yeem txo cov ntsiab lus molybdenum qis dua tus qauv. Qhov no "txo version" 316 yog qhov yooj yim rau xeb pob hauv ib puag ncig nrog cov tshuaj chlorine (xws li cov chaw ntug dej hiav txwv).
Qhov sib txawv ntawm cov qauv duplex:Kev lig kev cai 316 yog ntawm cov qauv austenitic, thaum hom tshiab ntawm duplex stainless hlau (austenitic + ferritic) muaj qhov sib txawv ntawm cov khoom siv vim muaj qhov sib txawv microstructures. Cov qauv duplex tuaj yeem nthuav tawm ntau yam luster tom qab polishing thiab tuav lub ntsej muag zoo dua.
II. Kev Siv Tshuab: Hloov los ntawm Hlau Phaj rau Artwork
Kev kho deg technology:Los ntawm ultra- ci iav tiav (8K) mus rau thev naus laus zis- tau tshoov siab txhuam txhuam tiav, thiab tom qab ntawd mus rau electrolytic polishing (EP) uas tsim cov txheej txheej ci ntsa iab, cov txheej txheem sib txawv tau muab cov yam ntxwv tsis pom kev zoo. Cov nyhuv iav yuav tsum muaj qhov tseeb heev hauv qhov flatness ntawm daim ntawv, thaum lub txhuam txhuam tuaj yeem zais me ntsis khawb.
Kev tsim cov txheej txheem cuam tshuam:Qhov saum npoo ntawm cov ntawv txias- dov yog du dua li ntawm cov ntawv kub - dov. Tsis tas li ntawd, cov txheej txheem vuam kuj tseem ceeb heev. Yog tias tsis muaj kua qaub ntxuav thiab kev kho mob passivation tom qab vuam, qhov chaw vuam yuav ua rau muaj kev zoo nkauj.
III. Kev ntsuam xyuas ib puag ncig: Kub tsis ntshai hluav taws.
Chloride ion corrosion kuj:Nyob rau hauv dej hiav txwv thiab ntsev tsuag ib puag ncig, 316 stainless hlau yuav raug kev txom nyem los ntawm pitting vim kev nkag mus ntawm chloride ions los ntawm passivation zaj duab xis. Qhov ntau corrosion-resistant S32001 duplex stainless hlau ua tau zoo dua nyob rau tib qhov chaw.
Acid- puag thiab kub siab:Hauv cov khoom siv tshuaj, cov kua qaub yuav ua rau huab cua-zoo li oxide txheej; ntawm qhov kub thiab txias, 316 stainless hlau tuaj yeem raug rhiab heev, ua rau txo qis ntawm qhov gloss. Siv cov hlau tsis muaj hlau nrog cov ntsiab lus qis dua (316L) lossis kev kho tshwj xeeb tuaj yeem txo cov teeb meem no.
IV. Kev ua lag luam ntxiab: Cov cuab yeej thiab "316 cuav"
Material adulteration:Pheej yig 201 stainless hlau (tsis muaj molybdenum) yog siv los xyaum 316, thiab cov khoom sib txawv yog zais los ntawm sandblasting los yog electroplating. Cov khoom no pib tshwm sim zoo ib yam, tab sis xeb pib tsim tom qab 3-6 lub hlis ntawm kev siv.
Cov txheej txheem yooj yim:Txhawm rau txo cov nqi, cov txheej txheem tseem ceeb xws li polishing thiab passivation raug tshem tawm. Piv txwv li, qee lub khob insulated tsuas yog hauv qab ua los ntawm 316 cov khoom, thaum lub cev yog ua los ntawm 201 stainless hlau thiab tsis muaj electrolytic polishing, uas ua rau cov phab ntsa hauv cov ntxhib ntxhib uas nquag khaws cov av thiab cov kab mob.
Nrhiav kev dag ntxias:Cov ntaub ntawv qhia txog kev dag ntxias spectral yog siv los dag ntxias cov neeg siv khoom. Cov ntaub ntawv los ntawm cov chaw kuaj kev tshaj lij qhia tau hais tias kwv yees li 15% ntawm cov khoom sau npe "316 stainless hlau" tiag tiag muaj cov ntsiab lus molybdenum tsawg dua 1%.
V. Lub Qhov Muag Ntsej Muag: 4 Lub Tswv Yim rau Kev Xaiv Qhov Tseeb 316 Cov Khoom Uas Ua Los Ntawm Cov Khoom Zoo -Zoo Khoom siv
1. Saib xyuas qhov ci ntsa iab
High- cov khoom zoo yuav tsum nthuav tawm cov xim hlau zoo nkauj yam tsis muaj xim sib txawv lossis oxidation me ntsis. Daim iav saum npoo qhia txog lub teeb kom meej meej yam tsis muaj kev cuam tshuam, thiab qhov txhuam txhuam tau zoo ib yam kev coj ua.
2. Kov qhov kev ntxhib los mos
Qhov saum npoo ntawm cov khoom uas tau dhau los ntawm electrolytic polishing yog du zoo li daim iav, tsis muaj qhov nplaum; thaum electroplated los yog tshuaj tsuag cov khoom yuav muaj ib tug grainy xav.
3. Tshawb xyuas cov ntawv pov thawj
Cov tuam txhab lag luam niaj hnub yuav sau cov ntaub ntawv qib (xws li "316"), cov qauv siv tau, thiab cov khoom siv ntau lawm. Tsis txhob yuav "peb-tsis muaj" cov khoom.
4. Ua ib qho kev sim yooj yim
Muab cov tshuaj tiv thaiv stainless hlau tso rau ntawm qhov chaw. Yog tias nws tsis hloov xim hauv 3 feeb, nws yog 316 stainless hlau; Yog tias nws tig liab sai, nws yog 201 lossis 202 stainless hlau.
Xaus
Qhov sib txawv ntawm qhov zoo li ntawm 316 stainless hlau yog qhov tseem ceeb ntawm kev xav txog cov ntaub ntawv tshawb fawb, kev siv thev naus laus zis, thiab kev ua lag luam ncaj ncees. Thaum cov neeg siv khoom yuav khoom, lawv tsis tsuas yog yuav tsum nkag siab txog qhov sib txawv ntawm cov txheej txheem, tab sis kuj yuav tsum tau ceev faj tiv thaiv kev lag luam chaos. Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua tau siab heev -zoo 316 stainless hlau cov khoom ib txwm ci nrog lub ci ci ntawm cov thev naus laus zis thiab kev ua tau zoo dhau sijhawm.
