Iyo 304 isina ngura simbi ngura?
Zuva parakatanga kukwira muguta, Mary akapinda muvharanda rake kuti ambofurwa nemhepo. Maziso ake akatenderera pamusoro pedenga raiyevedza achibva amira pamadziro evharanda rake. Zvakamushamisa, akaona madhaka akaita ngura pasimbi isina simbi. Mary akanga agara achidavira kuti simbi isina simbi haiviri ngura, asi zvino zvakaratidza kuti akanga asina kururama. Izvi zvakaita kuti azvibvunze kuti, ko 304 simbi isina tsvina inoita ngura here? Uye saka, akatanga rwendo rwake kuburitsa chokwadi kuseri kweiyi pfungwa isiriyo.
304 simbi isina tsvina ine yakakwirira kuramba ngura uye ngura. Nekudaro, haina kudzivirirwa zvachose kune ngura uye inogona corrode pasi pemamwe mamiriro, sekuratidzwa kune yakanyanya kuwanda kwemunyu kana kuratidzwa kwenguva refu kune acidic nharaunda.
Chinyorwa chino chicharamba chichikurukura mubvunzo uyu kubva pazvinhu zvinotevera:

Ndezvipi zvinhu zvinogona kukonzera 304 simbi isina tsvina kuita ngura?
304 simbi isina tsvina inozivikanwa nekunaka kwayo kwekudzivirira kusimba, asi mune mamwe mamiriro ezvinhu, inogona kuramba ichiita ngura.
Chimwe chezvikonzero zvikuru zvinogona kukonzera ngura kutarisana nenzvimbo dzakaoma, senge hunyoro hwakanyanya, mvura yemunyu, kana acidic mhinduro.
Chimwe chinhu kusvibiswa kwepamusoro, sekusangana nesimbi kana kabhoni simbi, iyo inogona kukonzera galvanic corrosion.
Pamusoro pezvo, kuchengetedza kana kubata zvisina kufanira kunogona kukonzera kuita ngura, sezvo zvikwambo kana matinji ari pamusoro anogona kugadzira nzvimbo dzekuti unyoro uye oxygen ipinde. Zvakakosha kuchengetedza uye kuchenesa simbi isina tsvina nguva nenguva kudzivirira kuita ngura.
Kuisa machira ekudzivirira, akadai sependi kana electroplating, kunogonawo kubatsira kuwedzera kuramba kwayo mukuora.
Nekunzwisisa zvinhu zvinogona kukonzera ngura, tinogona kutora matanho ekudzivirira uye kuwedzera hupenyu hwe304 simbi isina tsvina mumashandisirwo akasiyana.
304 simbi isina simbi chinhu chisingadzivirirwe necorrosion, asi haina kudzivirirwa zvachose mukuora. Kune nzira dzakawanda dzekudzivirira kubva kune ngura, dzinosanganisira:
Passive Dziviriro: Nzira yakajairika ndeyekungoita chengetedzo, iyo inosanganisira kugadzira yakatetepa, isingaonekwe layer yechromium oxide pamusoro pesimbi. Iyi danda inodzivirira simbi yepasi kubva kune zvakatipoteredza uye inodzivirira kuita ngura. Iyi nzira inoshanda chero bedzi nzvimbo yacho isina kukuvara kana kusvibiswa.
Coatings: Imwe nzira yekudzivirira 304 simbi isina tsvina ndeyekuisa coating, senge pendi kana poda coating. Aya mabhanhire anoita sechivharo pakati pesimbi uye zvakatipoteredza, kudzivirira unyoro uye oxygen kusvika pamusoro.
Kudzivirirwa kweCathodic: Iyi nzira inosanganisira kubatanidza simbi kune imwe simbi inoshanda, senge zinc kana magnesium. Simbi idzi dzinoita ngura nekukurumidza kupfuura simbi isina tsvina, dzichizvipira kudzivirira simbi yacho kuti isaita ngura.
Kucheneswa Kwakakodzera uye Kuchengeta: Kugara uchichenesa uye kugadzirisa kunogona kubatsira kudzivirira kuita ngura nekubvisa zvinosvibisa uye kuita kuti pasi pakaoma.
Nekutevera nzira idzi, zvinokwanisika kudzivirira kuita ngura uye kurebesa hupenyu hwe304 simbi isina tsvina mumashandisirwo akasiyana siyana, kusanganisira kuvaka, kugadzira chikafu, uye michina yekurapa.
Ko 304 simbi isina tsvina ingadzivirirwe sei kuti isaita ngura?
Ko 304 simbi isina tsvina yakawedzera kana kushomeka kuita ngura kana ichienzaniswa nemamwe marudzi esimbi isina tsvina?
Kana zvasvika kune simbi isina tsvina, zita chete rinogona kunyengera. Haasi ese masimbi asina tsvina anosikwa akaenzana, uye imwe neimwe ine yayo yakasarudzika midziyo inokanganisa kurwisa kwayo ngura. Nepo 304 simbi isina tsvina ichizivikanwa nekunakisisa kwayo corrosion resistance, haidzivirirwe nekuita ngura. Muchokwadi, zvichienderana nenzvimbo chaiyo, inogona kunge yakanyanya kana kushomeka kuita ngura kana ichienzaniswa nemamwe marudzi esimbi isina tsvina.
Semuyenzaniso, 316 simbi isina tsvina ine molybdenum, iyo inokwidziridza kusakara kwayo munzvimbo dzine hukasha dzakadai senzvimbo dzemugungwa. Kune rimwe divi, 430 Stainless simbi ine yakakwira huwandu hwechromium asi isina nickel, inoita kuti itengeke asi zvakare isingaite ngura pane 304 simbi isina tsvina.
Muchidimbu, kuita ngura kwesimbi isina tsvina kunoenderana nemakemikari ayo uye nharaunda yainoshandiswa. Nepo 304 simbi isina simbi iri sarudzo yakakurumbira kune yayo yese kusaita ngura, inogona kunge isiri iyo yakanakisa sarudzo pane yega application.
Kana zvasvika pakuita ngura, 304 simbi isina simbi inogona kuita zvishoma.
Kunyanya, kuvepo kwemakemikari kana mvura yemunyu inogona kukanganisa zvakanyanya kugona kwayo kurwisa ngura. Kana yaiswa mumakemikari ane hasha kana mvura yemunyu, 304 simbi isina tsvina inogona kunyanya kuve panjodzi yekuora uye ngura.
Izvi zvinodaro nekuti zvinhu izvi zvinogona kuputsa passive layer yechromium oxide inodzivirira simbi kubva kuita ngura. Kana iyo passive layer ikakanganiswa, simbi inoratidzirwa kune okisijeni uye unyoro, izvo zvinogona kutungamirira kukugadzira ngura.
Kurwisa izvi, zvakakosha kushandisa giredhi rakakodzera resimbi isina tsvina uye kuona kuti yacheneswa uye inochengetedzwa kuti idzivirire kubva kumakemikari ane hutsinye uye kuratidzwa kwemvura yemunyu.
Kuvapo kwemakemikari kana mvura yemunyu kunokanganisa sei ngura ye304 simbi isina tsvina?
Ko simbi yakasvibiswa 304 ichiri kushandiswa mumashandisirwo akasiyana siyana?
Kana zvasvika pakuora 304 simbi isina tsvina, mhinduro haisi yakatwasuka nguva dzose. Zvinoenderana nekuoma kwe ngura uye kushandiswa kwakananga kwezvinhu.
Kazhinji, ngura diki inogona kusanyanya kukanganisa kushanda kwesimbi isina tsvina, kunyanya kana iri munzvimbo isina kupisa.
Zvisinei, mune mamwe maitiro akaoma, akadai seaya anosanganisira kusangana nezvokudya kana makemikari, kunyange ngura duku inogona kuita kuti chinhu chacho chisashandiswa.
Muzviitiko izvi, zvakakosha kunyatsochenesa uye kugadzirisa chero nzvimbo dzine ngura, kana kutsiva zvinhu zvachose kuti uve nechokwadi chekushanda kwakanaka uye kuchengeteka.
Senguva dzose, kudzivirira ndiyo nzira yakanakisisa yekuita, saka kuchengetedza nguva dzose uye kuchengetedza kwakakodzera kunogona kubatsira kudzivirira kuita ngura uye kuwedzera hupenyu hwe304 simbi isina tsvina mumashandisirwo akasiyana-siyana.
mhedziso
Mubvunzo wekuti 304 simbi isina tsvina inowanzoitika, uye mhinduro ndeyokuti inogona mune mamwe mamiriro ezvinhu. Zvinhu zvinogona kukonzera ngura zvinosanganisira kusangana nezvinhu zvinoora, tembiricha yakanyanya, uye kukuvara kwemagetsi.
Kuti udzivise kuita ngura, zvakakosha kushandisa nzira dzakakodzera dzekuchenesa, kudzivisa kutarisana nemhoteredzo dzakaoma, uye kuisa marashi ekudzivirira. 304 simbi isina tsvina haiwanzo kuita ngura kana ichienzaniswa nedzimwe mhando dzesimbi isina tsvina, asi kuratidzwa nemvura yemunyu kana makemikari kunogona kukurumidza kuita. Yakaraswa 304 simbi isina tsvina inogona kuramba ichishandiswa mune mamwe maapplication, asi zvakakosha kuti uongorore kutendeseka kwayo kwechimiro uye kutora matanho akakodzera kudzivirira imwe corrosion.
Pakazere, kuchengetedza kwakaringana uye kudzivirira kunogona kuve nechokwadi chehupenyu hurefu uye kushanda kwe304 simbi isina tsvina mumhando dzakasiyana dzekushandisa.
