Stainless simbi chinhu chinoshamisa chinoita basa rakakosha mumaindasitiri akasiyana siyana, nekuda kwehunhu hwayo hwakasiyana uye kuita kusingaenzaniswi. Asi waizviziva here kuti pane chakavanzika chekuchengetedza kuita kwayo uye hupenyu hurefu? Chakavanzika ichi chiri muchiitiko chinonzi passivation.

Nhanganyaya kune Stainless Steel

Kunzwisisa simba rekufambisa kunotanga nekuonga zvakakosha zvesimbi isina tsvina pachayo. Simbi isina tsvina haisi chinhu chiri nyore;

ialloy yakagadzirwa nesimbi, kabhoni, uye ine rupo dosi yechromium.

Chii Chinoita Stainless Simbi Yakasarudzika

Mutambi akakosha munyaya yesimbi isina tsvina ndeye chromium. Kana yaiswa kuokisijeni, chromium inoumba chidimbu chisingaoneki chechromium

oxide pamusoro pesimbi. Iyi layer ndeyekuita, zvichireva kuti haina chekuita nechimwe chinhu.

1. Kunzwisisa Corrosion Resistance

Chromium oxide ingirozi inochengeta yesimbi isina tsvina. Inodzivirira ngura uye ngura, zvinova makomba akajairika emamwe simbi zhinji.

Uku kuramba kwecorrosion kunopa simbi isina tsvina zita rayo uye kushandiswa kwayo kwakapararira.

2. Basa rePasivation muStainless Steel

Zvino, ngatinyure mumusoro wenyaya - passivation. Passivation ikemikari nzira inosimudzira inowanzoitika chromium oxide layer.

Izvi zvinoita kuti simbi iyi irambe ichiita ngura nekuora.

3. The Sayenzi Kuseri kwePasivation

Munguva ye passivation, simbi isina tsvina inobatwa neine mild acid solution. Izvi zvinobvisa simbi yemahara uye zvimwe zvinosvibisa kubva pamusoro,

izvo zvinogona kukanganisa kuumbwa kwechromium oxide layer.

Ungade here kuziva kuti nei Stainless simbi ichida kupfuura?

Pakutanga, tinoda kuziva kuti chii chinorehwa nesimbi isina simbi? Kupfuura kwesimbi isina tsvina kunoreva kuita kuti pamusoro pesimbi isina tsvina iite neajenti yekufambisa kuti igadzire yakagadzikana passivation firimu inodzivirira simbi isina tsvina substrate kubva mukuora. zvinokonzerwa ne oxidation uye corrosion. Iyo ngura yekudzivisa kuita kwesimbi isina tsvina yakanaka. Zvisinei, munzvimbo dziri mumahombekombe egungwa kana kusangana nemamwe makemikari ane acid nealkali, maion anogadzirwa echloride anogona kupinda zviri nyore mufirimu resimbi resimbi. Simbi isina tsvina inoora zvishoma nezvishoma uye kuita ngura nekufamba kwenguva. Nokudaro, simbi isina tsvina inoda kupfuudzwa. Passivated simbi isina tsvina inogona kuvandudza iyo yekutanga anti-ngura hwaro nemakore 3-8, ichideredza zvakanyanya mukana wesimbi isina ngura.

HENGKO simbi isina tsvina sintered sefa chinhu chine chaiyo mhepo pore saizi, yunifomu sefa gomba saizi uye yunifomu kugovera; kunaka kwemhepo kupindirana, kutenderera nekukurumidza, yakanaka yekubata maitiro, yakanyanya kusefa kunyatsoita; yakanaka corrosion resistance, high-temperature resistance, heat shock resistance, simbi isina tsvina inogona kuita 600 Operation pakupisa kwepamusoro; kureba kweiyo yakanaka sefa chubhu inogona kusvika 800mm, iyo yakakura saizi yeiyo sefa plate chimiro inogona kusvika 800mm kureba * 450mm yakafara, uye iyo yakakura dhayamita yeyakatenderera sefa chimiro inogona kusvika 450mm. Isu tinopawo kufambiswa kwezvikamu zvechigadzirwa, Kana iwe uchida kunyorera kune yakasimba corrosion kuramba uye ngura kuramba nharaunda.

Benefits of Passivation

Kune akawanda mabhenefiti ekupfuura simbi isina tsvina, zvese izvo zvinobatsira mukusimudzira kushanda kwayo uye hupenyu hurefu.

Nzira yekuita sei passivation-stainless simbi?Rega tikuudze.

Nekuti mhando dzakasiyana dzesimbi isina tsvina dzinoshandisa musanganiswa wakasiyana wemakemikari ekufambisa, mamwe madeti achave akasiyana panguva yekupfuura kwesimbi isina tsvina. Passivation inoda tsika. Nekudaro, iyo yekutanga maitiro kazhinji ine matanho akafanana: Ita shuwa kuti pamusoro pechikamu chakachena. Chete kana iyo substrate yaiswa pachena inogona kuve nani passivated. Isa chikamu chimwe chete kana kuti akati wandei kuti apinzwe mumudziyo. Dururira mvura yemakemikari mumudziyo uye rega zvikamu zvinyure kwenguva yakati. Geza nemvura inoyerera. Ita shuwa kuti pamusoro pechikamu chakacheneswa uye pasina yakasara passivation fluid pa.

Nitric acid passivationndeimwe yeazvino basic passivation tekinoroji. Tisati tasarudza tekinoroji yepassivation, isu tinofanirwa kuziva mhinduro yemakemikari inodiwa kuti passivation reaction yesimbi isina simbi kudzivirira kushandisa mhinduro isiriyo kukonzera kukanganisa kwezvikamu. Uye panguva imwechete kusarudza yakabatana passivation tekinoroji zvinoenderana nehunhu hweakasiyana simbi isina tsvina. Semuyenzaniso, chromium content of austenitic stainless steel (senge 304 stainless steel) inowanzokwirira kudarika yemartensitic stainless steel (senge 430 stainless steel), zvichiita kuti austenitic alloys arambe achishingirira mukuora uye gomba.

Pamberi pekupfuura kwezvikamu zvesimbi isina tsvina, zvinotevera zvinofanirwa kutariswa:

Weldments inogona kunge isina kukodzera passivation. Iyo passive firimu iri pamusoro pesimbi isina tsvina inoita kuti irambe ichiita ngura. Arc welding inoisa izvo zvinhu kune ipfupi tembiricha yekupisa bhasikoro, nekudaro ichiparadza marara ayo ekuramba.

Iro tsika yekugeza yemakemikari inodiwa. Iyo tembiricha uye mhando yeasidhi inoshandiswa mukuita passivation inofanirwa kugadziridzwa zvinoenderana neiyo alloy iri kupfuudzwa. Izvi zvinowedzera mutengo uye kuoma kuenzaniswa ne electropolishing. Mamwe maalloys haagone kuvharwa. Semuyenzaniso, mamwe masimbi esimbi asina simbi ane yakaderera chromium uye nickel zvirimo achaparadzwa. Nokudaro, havagoni kuregererwa.

Kubatsira kukuru kwesimbi isina simbi passivation ndeyokuti inogona kuvandudza kupikisa kwesimbi yezvikamu zvesimbi, uye mutengo wakaderera pane we electropolishing. Izvo zvakanyanya kukanganisa kweiyo electropolishing process ndeyokuti inodhura kupfuura yakajairwa passivation process. Mukuwedzera, electropolishing haina mhedzisiro yakakosha pane inodzivirira oxide layer yesimbi senge passivation.

Nekudaro, kana uchitaura nezve mamiriro epamusoro ezvikamu mukutarisa kukuru, electropolishing ichiri iko kurapwa kwakasarudzika. Passivation haina kufanana ne electropolishing kuita kuti chikamu chechikamu chive chakatsetseka, zvakare hachichinji zvakanyanya kutaridzika kwechikamu. Naizvozvo, iyo passivation haisi nzira yakanaka kana chigadzirwa ichida yakatsetseka uye isina-tsvimbo. Maindasitiri ezvekudya nemishonga anowanzo shandisa maelectro-polished stainless steel padenga nekuti pasi pakatsetseka uye nyore kuchenesa nekuuraya utachiona.
