Stainless simbi isimbi ine alloy ine zvishoma chromium zviri 10.5%. Chromium inopindirana neokisijeni iri mumhepo uye inoita danda rekudzivirira rinoita kuti simbi isina tsvina isarambe ichiita ngura kana kuita ngura. Parizvino, pane anopfuura zana nemakumi mashanu emhando dzesimbi isina tsvina pamusika.

Nekuda kwechimiro chayo chekuchengetedza yakaderera, kuramba kune oxidation uye kusvibisa, simbi isina tsvina inofarirwa mune akawanda maapplication, kunyanya ayo ane basa aesthetics.

Kunyangwe iine zvinhu izvi zvinokatyamadza, simbi isina tsvina inogona uye inoita ngura mushure mezvose, 'haina tsvina' kwete 'stainfree'. Mamwe marudzi esimbi isina tsvina anowanzoita ngura kupfuura mamwe, zvichienderana nemukati wekromium. Iyo yakakwirira iyo chromium yemukati, kashoma simbi ingaite ngura.

Asi, nekufamba kwenguva uye kana isina kuchengetedzwa zvakanaka, ngura inogona uye inokura pasimbi isina tsvina.

Zvinhu Zvinokanganisa Ngura paStainless Simbi

Zvinhu zvakasiyana-siyana zvinogona kukanganisa kugona kwesimbi isina kusimba kuramba ngura. Kuumbwa kwesimbi ndiko kunonyanya kunetseka kana zvasvika pakudzivisa kuora. Zvinhu zviri mumagiredhi akasiyana esimbi isina tsvina zvinogona kuva nemhedzisiro yakaipa pakupokana nekuora.

Nzvimbo iyo simbi inoshandiswa ndechimwe chinhu chinogona kuwedzera mikana yesimbi isina tsvina. Nzvimbo dzine chlorine semadziva ekutuhwina dzinoita ngura zvakanyanya. Zvakare, nharaunda dzine mvura ine munyu dzinogona kukurumidza kuita ngura pasimbi isina tsvina.

Pakupedzisira, kuchengetedza kuchava nemigumisiro pane simbi kukwanisa kudzivisa ngura. Iyo chromium musimbi isina tsvina inopindirana neokisijeni mumhepo kugadzira inodzivirira chromium oxide layer pamusoro pepamusoro. Kunyange zvazvo yakaonda zvikuru, danda iri ndiro rinodzivirira simbi kuti isaora. Iyi nhanho inogona kuparadzwa nenzvimbo dzakaomarara kana kukuvadzwa kwemagetsi senge zvikwambo zvisinei, kana ikacheneswa zvakanaka uye munzvimbo yakakodzera, iyo yekudzivirira inoumba zvakare kudzorera zvinhu zvekudzivirira.

Mhando dzeStainless Steel Corrosion

Kune marudzi akasiyana e-stainless steel corrosion. Chimwe nechimwe chazvo chinopa matambudziko akasiyana uye chinoda kubata kwakasiyana.

• General corrosion - ndiyo inonyanya kufanotaurwa uye iri nyore kubata. Iyo inoratidzirwa nekurasikirwa kweyunifomu yepasi rose.
• Galvanic Corrosion - rudzi urwu rwekuora runokanganisa akawanda masimbi alloys. Inoreva mamiriro ezvinhu apo simbi imwe inosangana neimwe uye inoita kuti imwe kana zvose zvibatane uye zvigora.
• Pitting corrosion - imhando yenzvimbo yecorrosion inosiya makomba kana maburi. Inowanikwa munzvimbo dzine chlorides.
• Crevice corrosion - zvakare corrosion yenzvimbo inoitika pamukaha pakati penzvimbo mbiri dzinobatana. Zvinogona kuitika pakati pesimbi mbiri kana simbi uye isiri-simbi.

Maitiro ekudzivirira Stainless Simbi kubva kuNgura

Kusakara simbi isina tsvina kunogona kuve kunetseka uye kutaridzika kusingataridzike. Iyo simbi yakagadzirirwa kudzivirira ngura ndosaka vashandisi vazhinji vachitya pavanotanga kuona mavara uye ngura pasimbi. Sezvineiwo, kune nzira dzakasiyana-siyana pamatanho akasiyana dzinogona kubatsira kuvandudza ngura uye kusagadzikana kwemarara.

Design

Kugadzirira panguva yekuronga, kana uchishandisa simbi isina tsvina, inogona kubhadhara munguva refu. Iva nechokwadi chokuti simbi inoshandiswa munzvimbo dzine mvura shoma shoma kuti ideredze kukanganisa kwepamusoro. Mumamiriro ezvinhu apo kusangana nemvura kusingadzivisiki, maburi emvura anofanira kushandiswa. Iyo yakagadzirwa inofanirawo kubvumira kutenderera kwemhepo kwemahara kudzivirira kukanganisa kune alloy.

Fabrication

Panguva yekugadzira, kungwarira kwakasiyana kunofanirwa kunge kuri kutora nharaunda yakatenderedza kudzivirira kusvibiswa kwemuchinjiko nemamwe simbi. Zvese kubva kune zvishandiso, zvigadziriso zvekuchengetedza, kutendeuka rolls nemaketani zvinofanirwa kunyatsotariswa kuti zvisadonhedze tsvina mualloy. Izvi zvinogona kuwedzera kukwanisa kuumbwa kwe ngura.

Maintenance

Kana iyo alloy yaiswa, kugadzirisa nguva dzose kwakakosha mukudzivirira ngura, zvakare kudzikisira kufambira mberi kwechero ngura ingave yakatoumba. Bvisa ngura yakaumbwa uchishandisa michina kana makemikari nzira uye chenesa alloy nemvura inodziya nesipo. Iwe unofanirwawo kuvhara simbi nemucheka usingadziviriri.
