Kune simbi isina tsvina, inowanzoonekwa sesimbi isiri nyore kuita ngura, asi chaizvoizvo simbi isina tsvina inogonawo kuita ngura.Iyo ngura uye marara kuramba kwesimbi isina tsvina inokonzerwa nekuumbwa kwechromium-rich oxide film (passivation film) pamusoro payo.Uku kuramba ngura uye kusaita ngura zvine hukama.
Bvunzo dzinotaridza kuti kusaonda kwesimbi mumidziyo isina simba semhepo nemvura uye mune oxidizing media senge nitric acid inowedzera nekuwedzera kwechromium zviri musimbi.Kana iyo chromium yemukati yasvika imwe muzana, iyo corrosion resistance yesimbi inoshanduka kamwe kamwe., ndiko kuti, kubva nyore kusvika kune ngura kusvika kusiri nyore kuita ngura, uye kubva pakuora-inodzivirira kusvika kune-inodzivirira.
Kuti uedze kana iyo simbi isina tsvina valve inogona kuita ngura, iyo vharafu imwe chete inogona kuiswa munzvimbo dzakasiyana dzekuona uye kuenzanisa.
Mumamiriro ezvinhu akajairika, kana simbi isina tsvina yakaiswa munzvimbo yakaoma yakaoma, mushure menguva yakareba, valve haisi mumamiriro ezvinhu akanaka chete, asiwo isina ngura.
Uye kana vharuvhu yakaiswa mumvura yegungwa ine munyu wakawanda, inopera mukati memazuva mashoma.Naizvozvo, iyo corrosion resistance uye Stainless simbi zvimiro zveStainless simbi mavharuvhu zvinodawo kuyerwa zvinoenderana nenharaunda.
"Kubva pahunhu hwevharuvhu yesimbi isina tsvina pachayo, chikonzero nei isina tsvina ndechekuti pane denderedzwa re chromium-rich oxide firimu pamusoro payo kudzivirira maatomu ekunze eokisijeni uye zvimwe zvimedu kuti zvisakonzere kukuvadza kwechinhu. valve ine hunhu hwesimbi isina tsvina."Nyanzvi Zvisinei, kana membrane yakanganiswa nezvinhu zvakaita semhoteredzo, inoita ngura nekupinda kwemaatomu eokisijeni uye inoparadzana kubva kune iron ions.
Pane zvikonzero zvakawanda zvekuora kwemavharuvhu esimbi isina tsvina, senge electrochemical reaction pakati pe membrane uye mamwe simbi element particles kana guruva, uye kushandiswa kwemhepo yakanyorovesa sepakati kugadzira micro-battery cycle, iyo inoita simbi isina tsvina. pamusoro ngura.
Mumwe muenzaniso ndewekuti Stainless simbi yepamusoro firimu inosangana zvakananga nezvinwiwa zvinopisa zvakaita seasidhi yakasimba uye alkalis, zvichikonzera ngura zvichingodaro.Nokudaro, kuitira kuti valve yesimbi isina tsvina irege kuita ngura, zvakakosha kubhadhara kucheneswa kwezvinhu mukushandiswa kwezuva nezuva uye kuchengetedza nzvimbo yevhavha yakachena.
Saka, kana vharafu yesimbi isina tsvina yakasvibiswa, mushandisi angagadzirisa sei dambudziko iri?
Kutanga, zvinodikanwa kuchenesa uye kukwesha pamusoro pevhavha yesimbi isina tsvina nguva nenguva kubvisa zvakabatanidzwa uye kubvisa kunze zvinhu zvinokonzera ngura.
Chechipiri, 316 simbi isina tsvina inofanira kushandiswa munzvimbo dzegungwa, nokuti 316 zvinhu zvinogona kudzivisa kuora kwemvura yegungwa.
Chechitatu, kuumbwa kwemakemikari emamwe mapaipi esimbi asina tsvina pamusika haazadzise zvinoenderana nenyika uye haaite zvinodiwa zve304, saka zvinokonzeresa ngura.Panyaya iyi, nyanzvi dzakataura kuti kana vashandisi vakasarudza mavharuvhu esimbi, vanofanira kunyatsosarudza zvigadzirwa kubva kune vagadziri vane mbiri.Bund Stainless simbi vharafu, yakanakisa zvinhu, yakanaka mhando, isarudzo yako yaunovimba nayo ~
Kune mashoma mashoma mavharuvhu esimbi anoita ngura.Kazhinji, mavharuvhu ekuchengetedza akagadzirwa nesimbi isina tsvina akachengeteka uye asingaenzaniswi nezvimwe zvinhu.Naizvozvo, vharuvhu yechinhu ichi yakajairika munharaunda yeimwe midhiya ine njodzi, uye zvakare ndiyo kiyi yekuona kuita kwayo.
Mukuwedzera, mavharuvhu esimbi asina tsvina anowanzo sangana nemamwe ma media emvura, uye nharaunda inowanzonyorova, uye iyo anti-ngura yakanakira yerudzi urwu rwevhavha yakave yakakosha, uye inoita kuti rudzi urwu rwevhavha rurambe rwakasimba.Upenyu hwebasa hunowedzerwa zvikuru, uye simba risina kufanira rezvinetso zvinogona kuita ngura rinobviswa.
