Ngaba i-rust yentsimbi engama-304?
Njengoko ilanga laliqalisa ukuphuma esixekweni, uMary wangena kwibalcony yakhe ukuze onwabele impepho yakusasa. Amehlo akhe azulazula phezu kwesibhakabhaka esimangalisayo kwaye wema kwi-balcony yakhe. Okwamothusayo kukuba, wabona amabala anomhlwa kwintsimbi yentsimbi. UMary wayesoloko ekholelwa ukuba intsimbi engenakutyiwa ngumhlwa, kodwa ngoku kwafunyaniswa ukuba akachananga. Oku kwamkhokelela ekubeni azibuze, ngaba i-304 irusa intsimbi engatyiwayo? Kwaye ke, waqala uhambo lwakhe lokutyhila inyaniso emva kwale ngcamango iqhelekileyo.
I-304 yensimbi engenasici inokumelana okuphezulu nokugqwala kunye nokubola. Nangona kunjalo, ayikhuselekanga ngokupheleleyo kumhlwa kwaye inokonakala phantsi kweemeko ezithile, ezifana nokuba sesichengeni setyuwa eninzi okanye ukuba sesichengeni ixesha elide kwindawo ezineasidi.
Eli nqaku liza kuqhubeka nokuxoxa ngalo mbuzo kule miba ilandelayo:
Isiqulatho
Ziziphi izinto ezinokubangela ukuba i-304 insimbi engenasici ivuthe?
I-304 insimbi engenasici yaziwa ngokugqwesa kwayo ukumelana nokugqwala, kodwa phantsi kweemeko ezithile, isenako ukurusa.
Enye yezinto eziphambili ezinokubangela umhlwa kukuchanabeka kwindawo erhabaxa, njengokufuma okuphezulu, amanzi etyuwa, okanye izisombululo ezineasidi.
Enye into kukungcoliseka komhlaba, njengokuvezwa kwentsimbi okanye i-carbon steel, enokubangela ukubola kwegalvanic.
Ukongezelela, ukugcinwa okungafanelekanga okanye ukuphatha kakuhle kunokukhokelela ekugruleni, njengoko imikrwelo okanye izibonda eziphezu komhlaba zingenza iindawo zokufuma kunye neoksijini ukungena. Kubalulekile ukugcina nokucoca intsimbi engatyiwayo rhoqo ukunqanda ukurusa.
Ukusebenzisa iingubo ezikhuselayo, njengepeyinti okanye i-electroplating, kunokunceda ukwandisa ukuxhathisa kwayo ekudlekeni.
Ngokuqonda izinto ezinokubangela ukugqwala, sinokuthatha amanyathelo asebenzayo ukukhusela kunye nokwandisa ubomi be-304 yensimbi engenasici kwizicelo ezahlukeneyo.
I-304 insimbi engagqwaliyo yinto ekwaziyo ukumelana nomhlwa, kodwa ayikhuselekanga ngokupheleleyo ekuruseni. Kukho iindlela ezininzi zokuyikhusela ekuruseni, kuquka:
Ukukhuselwa kwePassive: Eyona ndlela ixhaphakileyo kukukhuselwa kwe-passive, okubandakanya ukudala umaleko omncinci, ongabonakaliyo we-chromium oxide kumphezulu wentsimbi. Lo maleko ukhusela intsimbi engaphantsi kokusingqongileyo kwaye ikhusela ukurusa. Le ndlela isebenza ngokude nje ukuba umphezulu ungonakaliswanga okanye ungcolisekile.
Iingubo: Enye indlela yokukhusela i-304 yensimbi engenasici kukusebenzisa i-coating, njengepeyinti okanye i-powder coating. Ezi zambatho zisebenza njengomqobo phakathi kwentsimbi kunye nokusingqongileyo, ukuthintela umswakama kunye ne-oksijini ekufikeleleni phezulu.
Ukukhuselwa kweCathodic: Le ndlela ibandakanya ukudibanisa intsimbi kwintsimbi esebenzayo, njenge-zinc okanye i-magnesium. Ezi zinyithi zidleka ngokukhawuleza kunentsimbi engatyiwayo, zizincama ukuze zikhusele intsimbi ingavuthwa.
Ukucoca nokugcinwa ngokufanelekileyo: Ukucoca kunye nokugcinwa rhoqo kunokunceda ukuthintela ukugqwala ngokususa izinto ezingcolileyo kunye nokugcina indawo yomile.
Ngokulandela ezi ndlela, kunokwenzeka ukukhusela ukugqwala kunye nokwandisa ubomi be-304 yensimbi engenasici kwizicelo ezahlukeneyo, kubandakanywa ukwakhiwa, ukulungiswa kokutya kunye nezixhobo zonyango.
Ingakhuselwa njani i304 yentsimbi engatyiwayo ekuruseni?
Ngaba i-304 yentsimbi engatyiwayo ithanda ukurusa ngakumbi okanye ngaphantsi xa ithelekiswa nezinye iintlobo zentsimbi engatyiwayo?
Xa kufikwa kwintsimbi engenasici, igama lodwa linokukhohlisa. Ayizizo zonke iintsimbi ezingenasici ezidalwe zilingana, kwaye nganye ineempawu zayo ezizodwa ezichaphazela ukuchasana kwayo nomhlwa. Ngelixa i-304 yentsimbi engatyiwayo yaziwa ngokugqwesa kwayo ukumelana nokugqwala, ayikhuselekanga ekuruseni. Enyanisweni, ngokuxhomekeke kwindawo ethile, inokuba ngaphezulu okanye ngaphantsi kwe-rust xa kuthelekiswa nezinye iintlobo zentsimbi ecocekileyo.
Ngokomzekelo, i-316 insimbi engenasici iqulethe i-molybdenum, eyandisa ukuxhathisa kwayo kwi-corrosion kwiindawo ezinobundlobongela ezifana neendawo zaselwandle. Ngakolunye uhlangothi, i-430 insimbi engenasici inesixa esiphezulu se-chromium kodwa ayikho nickel, iyenza ifikeleleke ngakumbi kodwa ikwazi ukumelana nokubola kune-304 yensimbi engenasici.
Ngamafutshane, ukurusa kwensimbi engenasici kuxhomekeke kubume bekhemikhali kunye nendawo esetyenziswa kuyo. Ngelixa i-304 yensimbi engenastainless ilukhetho oludumileyo lokuxhathisa umhlwa, isenokungasoloko ilolona khetho lufanelekileyo kwisicelo ngasinye.
Xa kufikwa ekuruseni, i-304 intsimbi engatyiwayo inokuba mncinci.
Ngokukodwa, ubukho beekhemikhali okanye amanzi etyuwa anokuchaphazela kakhulu amandla ayo okumelana nomhlwa. Xa ibekwe kwimichiza erhabaxa okanye emanzini anetyuwa, i-304 steel stainless steel inokuba sesichengeni sokutya nomhlwa.
Oku kungenxa yokuba ezi zinto zinokwaphula umaleko wechromium oxide okhusela intsimbi kumhlwa. Ukuba umgca we-passive uphazamisekile, insimbi ibonakaliswe kwi-oksijini kunye nomswakama, oku kunokukhokelela ekubunjweni kwe-rust.
Ukulwa noku, kubalulekile ukusebenzisa umgangatho ofanelekileyo wensimbi engenasici kwaye uqinisekise ukuba icocwe ngokufanelekileyo kwaye igcinwe ukuze ikhuseleke kwiikhemikhali ezinzima kunye nokuvezwa kwamanzi etyuwa.
Ubukho beekhemikhali okanye amanzi etyuwa buchaphazela njani ukurusa kwe-304 yentsimbi engatyiwayo?
Ngaba i-rusted 304 yentsimbi engatyiwayo isenokusetyenziswa kwizicelo ezahlukeneyo?
Xa kuziwa kwi-rusted 304 yensimbi engenasici, impendulo ayisoloko ithe ngqo. Kuxhomekeke kubunzima bomhlwa kunye nokusetyenziswa okuthe ngqo kwezinto eziphathekayo.
Ngokuqhelekileyo, i-rust encinci ayinakuchaphazela kakhulu ukusebenza kwensimbi engenasici, ngakumbi ukuba ikwindawo engabonakaliyo.
Nangona kunjalo, kwizinto ezibaluleke ngakumbi, ezifana nezo zibandakanya ukudibana nokutya okanye iikhemikhali, nomhlwa omncinci unokwenza ukuba izinto zingasebenzi.
Kule meko, kubalulekile ukucoca ngokucokisekileyo kunye nokulungisa nayiphi na indawo egrunjiweyo, okanye ukubuyisela izinto eziphathekayo ngokupheleleyo ukuze kuqinisekiswe ukusebenza kakuhle kunye nokhuseleko.
Njengamaxesha onke, ukukhusela kuyona ndlela ilungileyo yokwenza, ngoko ke ukugcinwa rhoqo kunye nokugcinwa okufanelekileyo kunokunceda ukukhusela ukugqwala kunye nokwandisa ubomi be-304 yensimbi engenasici kwizicelo ezahlukeneyo.
isiphelo
Umbuzo wokuba i-304 i-rust yensimbi engenasici yinto eqhelekileyo, kwaye impendulo kukuba iyakwazi phantsi kweemeko ezithile. Izinto ezinokubangela umhlwa ziquka ukuchanabeka kwizinto ezidlayo, amaqondo obushushu aphezulu kunye nomonakalo owenziwe ngumatshini.
Ukuthintela ukugqwala, kubalulekile ukusebenzisa iindlela ezifanelekileyo zokucoca, ukuphepha ukuchanabeka kwindawo erhabaxa, kwaye usebenzise iingubo zokukhusela. I-304 intsimbi engatyiwayo ayifane ithande ukurusa xa ithelekiswa nezinye iintlobo zentsimbi engatyiwa, kodwa ukuvezwa kumanzi anetyuwa okanye imichiza kunokukhawulezisa inkqubo. I-Rusted 304 insimbi engenasici isenokusetyenziswa kwizicelo ezithile, kodwa kubalulekile ukuvavanya ukuthembeka kwayo kwesakhiwo kunye nokuthatha amanyathelo afanelekileyo okuthintela ukubola okuqhubekayo.
Ngokubanzi, ukugcinwa okufanelekileyo kunye nokukhuselwa kunokuqinisekisa ixesha elide kunye nokusebenza kwe-304 yensimbi engenasici kwizicelo ezahlukeneyo.
