Iziphathezi zeSteyinishi Zivikela Kanjani Ukuchithakala

Ukulwazi NgeNtando Yokuqina Kwethixoqo YeYisithuthi Esheshayo Yokwenza

Emhlabeni wamathuba ezenzulwini, insimbi engagqwali ikhoyili isingqiso sokubalaselela kwalabo bonke ababengi nokuthuthukisa kwemithombo. Inkinga yalo ekulahlweni kungcoliswa ngokusebenza kwezinhlayiya, izindlela zokwakha, nezinhlelo zokulungisa ihlathi.

Isiciqinisekiso esibonakalayo sokuba isilisa esikhawulayo secoil sahlukana nesilisa esisodwa kungumkhawulo wokungeniswa, okwenzeka kakhulu phakathi kwe-10.5% ne-30%. Xa kuthathwa amaxesha, umkhawulo wenza ibhara ephakeme engeyiyo eyancibilika ekuphazanyisweni, enyuselwa ngokuphindaphindwa, ekunika ukuphepha okudala kumathuba okuphazanyiswa. Le ngxelo yokunciphisa iyaphihlela ukuba imithwalo iphila ngempilo nangona ikuhlwayelwa ngemithwalo engcono.

Ubungakanani Bokuphazanyiswa

Umbiko Wokugcinwa Kwamathambo Nokwakha KweLeyeru Esebenzayo

Isiciqinisekiso sokuphazanyiswa kwesilisa esikhawulayo kusekelwe kumbiko wokugcinwa kwamathambo onjengoko wavelisiwe. Umthambo ophambili wokubanjwa, umkhawulo, unyusa ilayer ezingavaliyo yomkhawulo we-oxide xa uphendula amaxesha. Le layer, efuphi kuphela ngamathambo angamnye, isebenza njengebarrier engayihlukananga kumathuba aphazanyayo. Nakuba igunya libonakale, le layer ebopheleyo inyuselwa ngokushesha, ikunika ukuphepha okuphindaphinda.

Izinhlayiya zokudweba efanayo njenge-nikel, imolibdenama, nenitrojini zakhuthaza izici zokulindela ukuchithakala kwemithwalo. I-nikel isabalisa ubunzima beqondo eliphambili, ngelisho i-molibdenama ikhuthaza ukulindela kweziphazamiso nezichithako. Umehluko wokuxhumana kwezinhlayiya ezi zonke kwenza indlela yokulinda okuphephile kuzindlela zonke zokuchithakala.

Umboniso wesimo nasezinikeni

Umsebenzi wokukhiqiza kwesithuthi sezinkunkuma sokuchithakala kubangela umboniso wesimo, okwenzekayo kubangelwa ngokulindela kwalo kokuchithakala. Ukugaya nokulahla kwenza umboniso ohlelekile, ophephile okwenzela ukuthi kufutshane amaphuzu athintekayo apho ukuchithakala kungathembeka. Isimo sesayizi sinesidingo esikhulu futhi - izinhlangothi ezihlelele zanika amandla afutshane kumahluko lokuchitha ukuthi akwazi ukuthunyelwa futhi aqale ukwenza udvaba.

Izindlela zokwakha ezimoderna zihlanza ukwahlukanwa kwebhodi yesithombe nokulinganisa kwezimo, zikusiza ekuvikelweni okuphucile kumoya. Ukuqinisekisa okuhle kwezinkimbini ngaphakathi kwemisebenzi kungavimba ukuthi izimpande zibonakale emathilweni, okungakhomba amaphuzu avamile emsebenzi wokuvikela.

Imisebenzi Yokwakha Eyangeni Ukuvikela Kukumoya

Izindlela Zokulungisa Isandla

Kusetshenziswa izindlela ezahlukene zokulungisa isandla ukuze kuqinisekiswe ukuvikela okuphucile kohlelo lwesitsha esivelayo. Izilungiso zokuphazanyiswa zisusa umlilo ohleli kusandla futhi zangenhisa ibhodi yekhromiyam okhside. Ukulungiswa ngokwelektro kukudala isandla esigugu esiphansi okwesaba ukubamba kwebhakteriya futhi kuyakunciphisa inkohlakalo yokucula, okubaluleke kakhulu emisebenzini yezithelo nezempilo.

Izinkulungwane ezide emva kwezibalo zingakwethula ukukhathazeka kwe-corrosion. Lezi zingaba izibalo eziphucaka kakhulu zokuguquka kwamandla noma izibalo ezihle zezinhlayiya ezingakunika ukuphatha okudala ngaphandle kokugcina izici ezibalulekile zomthelelo. Ukukhethwa kwebala kubangelwa yindlela ekusetyenziswa ngayo nezimo zokuthembekile kumoya.

Ukuphatha nokuthetha Ukudibanisa

Imithetho engcono yokuhleleka kuyadinga ukuthi kubaluleke ukukhathazeka kwe-corrosion ekwakhiweni kwe-stainless steel coil. Abakhi abasebenzisa izindlela ezahlukene zokuchaza, kufana nozilingo lwe-salt spray, ukuchaza kwe-electrochemical, nokuzilondoloza kwezingu long-term exposure trials. Lezi zilingo ziqinisekisa iphumelelo lomthelelo phakathi kwezimo ezihlukene zokuthembekile kwe-corrosion bese zikunciphisa izinkinga zokwakha.

Ukubheka kahle kwezinhlobo zezimbi nokuthi yiniqhamo yesayizi ngaphakathi kokwakhiwa kusidla ukuthi ingxenye nganye ibe nemikhuba ethintekayo. Izindlela ezibonakala eziphuculi, kufana nesiphalamethu esiqondisa izimbi nezindlela zokubheka isayizi, ziyachaza ubunzima bezimbi nokwephiliswa kwazo.

Izinhloso Zamanzi Nokuhlanjelana Kwezenzo

Ukuziphatha Kwizimo Zamanzi

Izenzo zesithuthi sezinkuni enobumba siyahlukana ngokusho kwezimo zamanzi. Izinhloso ezifana nokwenzeka, uhluko, ukuthi kukhona izimbi, nokugcinwa kwezimali zihlukanisa indlela ayophila ngayo. Ukuziqonda lezi zinyathelo kusiza ekukhetheni i-ghreyidi neyisayizi efanele kumsebenzi wethu.

Imizimu yasehlabathini, imidwebo yezindustri, namathuba okusebenza kakhulu angaphezulu ayahlinzeka ngemiphumela engafanelekileyo. Isilinganiso se-chloride emzimbeni wamanzi, umzekelo, sikhomba ukuthi kudingeka ukuthi kutholakale izinhlobo ezinezinkinga eziphezulu zemolybdenum. Ngokufanayo, izimo ezinamathuba aphezulu kudinga izinhlobo ezingaqashelwa ubunzima balesigaba sokugcina phakathi kwamathuba aphezulu.

Ukunakekelwa Nokuphila isikhathi eside

Iindlela ezichanekileyo zokuphila kakhulu kuzinzile ekugcineni isikhathi eside sezindiza zesiStaini. Ukucula kanye kunciphisa ukukhula kwamathambo akhubazekayo kanye kunciphisa ubunzima besigaba sokugcina. Ukuqonda izithuthi nezindlela zokucula zihlenga ukuthi izenzo yokuphila kungazange zihlale zihlukanisa isandla sokugcina.

Ukubanenjalo kanye kuzo zonke izimo zingadinga ukulunga kancane-nje kanye nezinyathelo zokuphepha. Ukusebenzisa izinketho ezichanekileyo zokuphila kanye nezindlela zokuphatha kunciphisa ukugcinwa kwebhurkhazi yomthelela ngesikhathi eside sekusebenza.

Imibuzo Evame Ukubuzwa

Kutheni ukuba ikoyili yezilonda esiphazanywayo kahawukile kuzilonda ezenziwe ngokuvamile ngokubukeka kwebophazanyi?

Ikoyili yesilonda esiphazanywayo ishiyekela okungenani 10.5% kwe-chromium, okwakhiwa yilo ilaye ethulwane yesilonda esiphazanywayo xa isohlwa ngenqubo yokuxhala. Leli laye eliqinileyi libe yindlela eqhubekayo yokuphepha kwebophazanyi, ngempela kuzilonda ezivamile ezingenalo lo msebenzi wokubuyisa.

Ukuchophana kwesitinga kusenzelani njengoba kubophazanya nekoyili yesilonda esiphazanywayo?

Izinto zokulinganiselana njengezinkukhu, ubushushu, ukuthinta kwezimbi, nokugcinwa kwezixhobo zingathintana nobophazanyi bekoyili yesilonda esiphazanywayo. Izinhlobo ezahlukene namathreatment atholakala ukuze aphindekele imisebenzi emazingeni amahle, kusukela emazingeni aphazanywayo kuze kube kumasebe alohloko.

Ubuncinane obufunekayo ukugcina ubophazanyi bekoyili yesilonda esiphazanywayo?

Ukucula kahle ukususa izinkohlakalo, ukuphatha kahle ukuze kugcinwe indawo ephansi iphazimise, nezikhathi ezikhathazekileyo zokuhlola kubaluleke. Ukusebenzisa i-agensi nokusebenza okufanelekileyo ekuculeni kunciphisa ubungako beqondo eliphambili futhi libe yingozi yokukhupha ngokude.
