Thola Ukuphakama Kwezitini Ze-Silicon Carbide Ezidingweni Zakho Zezimboni

Embonini yesimanje, lapho ukusebenza kwezinga lokushisa eliphezulu kuyinto evamile, ukukhetha izinto eziphikisayo kungathinta kakhulu ukusebenza kahle, ukuqina, kanye nokusebenza kahle kwezinqubo zokukhiqiza. Izitini ze-silicon carbide zivele njengesixazululo esihamba phambili, zinikeza inhlanganisela eyingqayizivele yezakhiwo ezenza zibe yinto ebalulekile ezinhlotsheni eziningi zezicelo.​

Izakhiwo Eziyingqayizivele Zomzimba Nezamakhemikhali​

Ukuqina Okuphezulu Nokumelana Nokuguguleka​

Izitini ze-silicon carbide zinobunzima obumangalisayo be-Mohs obungu-9, obucishe bufane nobedayimane. Lobu bunzima obuphezulu buzivumela ukuthi zikwazi ukumelana nokuguguleka okukhulu okuvela ezinhlayiyeni zesivinini esiphezulu, izinto ezincibilikisiwe, kanye nokuhlanzwa kwemishini. Ezimbonini ezifana nezezimayini, i-metallurgy, kanye nokukhiqizwa kwesimende, lapho imishini ihlala ibhekene nezinto ezigugulekayo, ukusetshenziswa kwezitini ze-silicon carbide kungandisa kakhulu impilo yesevisi yezingcezu zesithando, amapayipi, nezinye izinto ezibalulekile. Isibonelo, kuma-oven esimende, uhlobo lokuguguleka kwezinto zokusetshenziswa kanye nendawo eshisayo ephezulu kungabangela ukuguguleka okusheshayo kwezinto zendabuko eziphikisayo. Izitini ze-silicon carbide, ngokumelana kwazo okuvelele kokuguguleka, zingabekezelela lezi zimo ezinzima, zinciphise imvamisa yokugcinwa nokufakwa esikhundleni, futhi ekugcineni zinciphise izindleko zokukhiqiza.​

Ukushisa Okuhle Kakhulu​

Esinye sezici ezibalulekile zezitini ze-silicon carbide ukuhanjiswa kwazo okuphezulu kokushisa. Le mpahla ivumela ukudluliselwa kokushisa okusebenzayo ngaphakathi kwezitofu zezimboni kanye nama-reactor. Ezisetshenzisweni lapho kudingeka khona imijikelezo yokushisa okusheshayo nokupholisa, njengasenqubweni yokukhiqiza ye-semiconductor yokufakelwa nokushisa, izitini ze-silicon carbide zingadlulisela ukushisa ngokushesha endaweni yokusebenza, ziqinisekise ukusatshalaliswa kokushisa okufanayo. Ngenxa yalokho, inqubo yokukhiqiza iba ngcono kakhulu, futhi ikhwalithi yomkhiqizo wokugcina iyathuthukiswa. Ngaphezu kwalokho, ukuhanjiswa okuphezulu kokushisa kwezitini ze-silicon carbide nakho kusiza ukunciphisa ukusetshenziswa kwamandla. Ngokuvumela ukudluliselwa kokushisa okusheshayo, amandla amancane ayachithwa ngendlela yokulahlekelwa ukushisa, okuholela ekongeni okukhulu kwezindleko zamandla ngokuhamba kwesikhathi.​

Ukuzinza Okuhle Kakhulu Kokushisa​

Izitini ze-silicon carbide zingagcina ubuqotho bazo besakhiwo kanye nezakhiwo zazo zomshini emazingeni okushisa aphezulu kakhulu, kuze kufike ku-1800°C (3272°F) kwezinye izimo. Lokhu kuzinza kokushisa okumangalisayo kuzenza zifanelekele ukusetshenziswa ezithandweni zokushisa okuphezulu, njengalezo ezisetshenziswa ekukhiqizweni kwensimbi, izinsimbi ezingezona i-ferrous, kanye nengilazi. Esithandweni sokwenza insimbi, isibonelo, ulwelwesi ludinga ukumelana nokushisa okukhulu kwensimbi encibilikisiwe kanye nokujikeleza kokushisa okuqhubekayo ngesikhathi senqubo yokukhiqiza. Izitini ze-silicon carbide zingabekezelela lezi zimo ngaphandle kokuguquka okukhulu noma ukuwohloka, zinikeze isivikelo esithembekile segobolondo lesithando futhi ziqinisekise ukusebenza kahle kokukhiqiza.​

Ukumelana Okuphezulu Kwamakhemikhali​

Lezi zitini zibonisa ukumelana okuhle kakhulu nezinto ezi-acidic kanye ne-alkaline. Ezimbonini zamakhemikhali, lapho kusetshenziswa khona amakhemikhali aqothulayo ngobuningi, izitini ze-silicon carbide zingasetshenziswa ukufaka ama-reactor, amathangi okugcina, kanye namapayipi. Zingamelana ngempumelelo nokugqwala kwama-acid ahlukahlukene, ama-alkali, kanye nosawoti, zivimbele ukuvuza futhi ziqinisekise ukusebenza okuphephile kwemishini. Isibonelo, ekukhiqizweni komanyolo, lapho ama-acid aqinile nama-alkali ebandakanyeka enkambisweni yokukhiqiza, izitini ze-silicon carbide zinikeza isivikelo esihlala isikhathi eside ngokumelene nokugqwala kwamakhemikhali, kunciphisa ingozi yokwehluleka kwemishini kanye nokungcola kwemvelo.​

Izicelo Ezihlukahlukene Ezimbonini Eziningi​

1. Imboni Yezinsimbi​

Ukwenza insimbi:Enkambisweni yokwenza insimbi, izitini ze-silicon carbide zisetshenziswa ezitsheni zikagesi ze-arc, ama-ladle, kanye nama-tundishes. Ukushisa kwazo okuphezulu kusiza ekufudumaleni nasekuncibilikiseni insimbi ngokushesha, kuyilapho ukumelana kwazo okuhle kakhulu nensimbi encibilikisiwe kanye nokuguguleka kwe-slag kuqinisekisa ukuhlala isikhathi eside kolwelwesi lwesithando. Lokhu akugcini nje ngokuthuthukisa ukusebenza kahle kokukhiqizwa kwensimbi kodwa futhi kunciphisa isidingo sokuphinda kufakwe ulwelwesi njalo, okuyinqubo ethatha isikhathi futhi ebiza kakhulu.​

Ukuncibilikisa Insimbi Okungeyona Insimbi:Ukuze kuncibilikiswe izinsimbi ezifana ne-aluminium, ithusi, ne-zinc, izitini ze-silicon carbide nazo zisetshenziswa kabanzi. Ekuncibilikiseni i-aluminium, isibonelo, izitini zisetshenziswa kumaseli e-electrolytic kanye nasezitsheni zokubamba. Ukumelana kwazo nemiphumela yokugqwala kwe-aluminium encibilikisiwe kanye nosawoti ohambisana nayo, kanye nokuqina kwazo okuphezulu kokushisa, kuzenza zibe ukukhetha okuhle kokugcina ubuqotho bemishini yokuncibilikisa nokuqinisekisa inqubo yokukhiqiza eqhubekayo.​

2. Imboni Ye-Ceramic Nengilazi​

Ukukhiqiza i-Ceramic:Kumahhavini e-ceramic, izitini ze-silicon carbide zisetshenziswa njengefenisha ye-oven, okuhlanganisa amashalofu, izisekelo, kanye nama-saggers. Amandla azo aphezulu emazingeni okushisa aphezulu azivumela ukuthi zithwale isisindo semikhiqizo ye-ceramic ngesikhathi sokudubula, kuyilapho ukuhanjiswa kwazo okuhle kokushisa kuqinisekisa ukufudumala okufanayo kwe-ceramics. Lokhu kuphumela emikhiqizweni ye-ceramic esezingeni eliphezulu enombala nokuthungwa okuhambisanayo. Ngaphezu kwalokho, impilo ende yefenisha ye-silicon carbide kiln inciphisa izindleko zokushintsha kanye nesikhathi sokungasebenzi ekukhiqizweni kwe-ceramic.​

Ukukhiqizwa Kwengilazi:Ezitsheni zeglasi, izitini ze-silicon carbide zisetshenziswa ezindaweni lapho kukhona khona izindawo ezinokushisa okuphezulu kanye nezokugqwala, njengegumbi lokusha kanye nendawo yokuncibilika kwengilazi. Zingamelana nengilazi encibilikisiwe enokushisa okuphezulu kanye nesenzo sokugqwala samakhemikhali akha ingilazi, okuhlinzeka ngokuvikela okuthembekile kanye nokuvikela isakhiwo sesithando. Lokhu kusiza ukuthuthukisa ukusebenza kahle kokuncibilika kwengilazi kanye nekhwalithi yengilazi ekhiqizwayo.​
Ukukhiqizwa Kwamandla Nokushiswa Kwemfucuza​.

Izitshalo Zikagesi:Ezitshalweni zamandla ezisebenzisa amalahle, izitini ze-silicon carbide zisetshenziswa kuma-boilers nasezinhlelweni zokuphatha umlotha. Zingamelana nokuguguleka komlotha ompukane kanye nendawo yokusha eshisa kakhulu, okuthuthukisa ukuthembeka nokusebenza kahle kwemishini yokukhiqiza ugesi. Ngaphezu kwalokho, ezitshalweni zamandla ezisebenzisa i-biomass, lapho ukusha kwe-biomass kukhiqiza amagesi agqwalisayo kanye nomlotha, izitini ze-silicon carbide zinikeza ukumelana okuhle kakhulu nalezi zimo ezinzima, okuqinisekisa ukusebenza okuzinzile kwesitshalo samandla.​

Izitshalo Zokushisa Udoti:Ukushiswa kwemfucuza kuhilela ukushiswa kwezinga lokushisa eliphezulu kwezinto ezahlukahlukene ezilahlwayo, okungakhiqiza amagesi alahlwayo kakhulu kanye nomlotha. Izitini ze-silicon carbide zisetshenziswa elayini lama-incinerator ukuze zimelane nalezi zimo ezimbi kakhulu. Ukumelana kwazo namakhemikhali kuvikela izindonga zama-incinerator ekugqwaleni, kuyilapho ukuzinza kwazo kwezinga lokushisa eliphezulu kuqinisekisa ukusebenza okuphephile nokuphumelelayo kwenqubo yokushiswa kwemfucuza.​
