Uma kukhulunywa ngezimo ezishisa kakhulu—kusukela ezithandweni zezimboni kuya ezindlini zomlilo zokuhlala—into eyodwa ivelele njengomgogodla wokuqina kwesakhiwo:udaka oluphikisayo lobumba. Yakhelwe ukumelana nokushisa okukhulu, ukuguguleka kwamakhemikhali, kanye nokushaqeka kokushisa, lolu daka olukhethekile lungaphezu nje "kweglu" yezitini ezimelana nokushisa. Luyingxenye ebalulekile eqinisekisa ukuphepha, ukusebenza kahle, kanye nokuphila isikhathi eside lapho izitini ezivamile zingadilika khona. Kungakhathaliseki ukuthi usemkhakheni wokukhiqiza, wokwakha, noma wokuthuthukisa ikhaya lakho, ukuqonda ukusetshenziswa kanye nezinzuzo zodaka olumelana nokushisa kungaguqula amaphrojekthi akho okushisa okuphezulu.
Okokuqala nokubaluleke kakhulu, izitofu zezimboni nama-oven yizona ndawo yokudlala eyinhloko yodaka olunamathelayo lobumba. Ezindaweni zokugaya insimbi, ezimbonini zengilazi, ezitshalweni zesamente, nasezindaweni zokukhiqiza i-ceramic, izitofu zisebenza emazingeni okushisa angaphezu kuka-1,000°C (1,832°F) amahora noma ngisho nezinsuku eziningi. Udaka oluvamile lwesamente lwasePortland luyancibilika noma lubole ngalezo zimo ezimbi kakhulu, okuholela ekwahlulekeni kwesakhiwo, ukuvuza, kanye nesikhathi sokungasebenzi esibizayo. Nokho, udaka olunamathelayo lobumba lwenziwe ngobumba oluhlanzekile kakhulu, i-silica, kanye nezinye izinto ezinamathelayo ezigcina amandla azo okubopha kanye nesimo kulezi zimo zokushisa eziqinile. Luvala izikhala phakathi kwezitini ezinamathelayo, luvimbele ukulahlekelwa ukushisa okunganciphisa ukusebenza kahle kwamandla ngamaphesenti angama-30. Kwabasebenzi bezimboni, lokhu kusho ukwehlisa izikweletu zamandla, ukuphazamiseka okuncane kokulungisa, kanye nokuhambisana nezindinganiso zokuphepha eziqinile.
Ngaphandle kwezimboni ezisindayo, udaka oluyi-clay refractory luyinto ebalulekile ezinhlelweni zokushisa zezentengiselwano nezezindlu. Izindawo zomlilo, izitofu ezishisa izinkuni, kanye ne-chimney liner zithembele kulo ukudala isithiyo esivikelekile nesimelana nokushisa. Cabanga ngokukhanyisa umlilo opholile egumbini lakho lokuphumula ukuze udaka olubamba izitini zakho zomlilo ndawonye luqhekeke futhi lukhiphe umusi onobuthi—lokhu kuyingozi yokusebenzisa udaka olungayi-refractory. Udaka oluyi-clay refractory alugcini nje ngokubekezelela imijikelezo yokushisa nokupholisa ephindaphindwayo yezindawo zomlilo zokuhlala kodwa futhi lumelana nemikhiqizo ebhubhisayo yokhuni oluvuthayo noma amalahle. Kulula ukuxuba nokusebenzisa, okwenza kube ukukhetha okuphezulu kwabakhi abangochwepheshe kanye nabathandi be-DIY ngokufanayo. Abanikazi bezindlu abatshala imali endaweni entsha yomlilo noma abavuselela endala bazothola ukuthi ukusebenzisa udaka oluyi-clay refractory kuqinisekisa ukuthi isici sabo sokushisa sihlala amashumi eminyaka ngaphandle kokubeka engcupheni ukuphepha.
Esinye isicelo esibalulekile izinqubo ze-petrochemical kanye nezensimbi. Izindawo zokuhlanza, izinsimbi zokuncibilikisa, kanye nezindawo zokukhiqiza izinsimbi azigcini nje ngokushisa okuphezulu kodwa futhi namakhemikhali anamandla—ama-acid, ama-alkali, kanye nezinsimbi ezincibilikisiwe ezingabhubhisa izitsha ezivamile. Ukungangeni kwamakhemikhali kwe-clay refractory mortar kwenza kube kuhle kakhulu emithanjeni yokusabela kwe-lining, izinto ezivuthayo, kanye nezinhlelo zokukhipha umoya. Kwakha uphawu oluqinile oluvimbela ukuvuza kwezinto eziyingozi, kuvikela abasebenzi kanye nemvelo. Ekuncibilikiseni i-aluminium, isibonelo, i-clay refractory mortar isetshenziselwa ukufaka amaseli e-electrolytic, lapho imelana nokugqwala okuvela kusawoti we-aluminium oncibilikisiwe kanye ne-fluoride. Lokhu kuthembeka yingakho kuyisinqumo esikhethwayo ezimbonini lapho ngisho nokuhluleka okuncane kungaba nemiphumela emibi kakhulu.
Udaka oluyi-refractory ludlala indima ebalulekile kuma-oven e-pizza nasemakhishini ebhizinisi. Ama-oven e-pizza ashiswa ngokhuni asebenza emazingeni okushisa aphakathi kuka-400°C no-500°C (752°F no-932°F), adinga udaka olungamelana nokushisa okukhulu ngaphandle kokuqhekeka noma ukulahlekelwa ukunamathela. Ama-pizza ochwepheshe kanye nabapheki basekhaya ngokufanayo bathembela udaka oluyi-refractory lodaka ukwakha nokulungisa lawa ma-oven, njengoba luqinisekisa ukusatshalaliswa kokushisa okuqhubekayo futhi luvimbela umusi noma ukushisa ukuthi kuphume. Emakhishini ebhizinisi, lusetshenziselwa ukufaka ama-grill, ama-rotisseries, kanye neminye imishini yokushisa okuphezulu, kugcinwa amazinga okuhlanzeka ngokuvimbela izinhlayiya zokudla ukuthi zingabanjwa udaka oluyi-refractory.
Yini ehlukanisa udaka oluyinqaba lobumba nezinye izinto eziyinqabayo? Ukuguquguquka kwalo kanye nokusebenza kahle kwezindleko. Ngokungafani nodaka oluyi-alumina ephezulu noma i-silica, oluklanyelwe amazinga okushisa aphezulu kakhulu kodwa luza nentengo ephezulu, udaka oluyinqaba lobumba lulinganisela ukusebenza kanye nokufinyeleleka kalula kwezicelo ezivame kakhulu zokushisa okuphezulu. Lutholakala ngesimo sempuphu, olungaxutshwa namanzi endaweni ukuze luhambisane nokuqina okufunwayo, kunciphisa izindleko zokulahla imfucuza kanye nezokuthutha. Ngaphezu kwalokho, lusebenza kahle kakhulu—abakhi bangakwazi ukulubumba nokululungisa kalula, baqinisekise ukubopha okuqinile phakathi kwezitini.
Ukukhetha udaka olufanele oluvikela ubumba kubalulekile empumelelweni yephrojekthi yakho. Funa imikhiqizo ehlangabezana nezindinganiso zemboni, njenge-ASTM C199, ecacisa izidingo zodaka oluvikela ubumba. Cabanga ngezinga lokushisa eliphezulu lokusetshenziswa kwakho, njengoba ezinye izidaka zobumba zenzelwe amazinga okushisa aphezulu kunezinye. Kumaphrojekthi ezimboni, khetha udaka olunezithasiselo ezengeziwe ezithuthukisa ukumelana nokushaqeka kokushisa kanye nokuqina kwamakhemikhali. Ukuze kusetshenziswe ekhaya, udaka olujwayelekile oluvikela ubumba luzokwanela izindawo eziningi zomlilo nezitofu.
Ekuphetheni, udaka oluyi-clay refractory luyinto ebalulekile kunoma yiluphi uhlelo lokusebenza oluhlanganisa amazinga okushisa aphezulu. Kusukela ezithandweni zezimboni kuya ezindlini zomlilo zasekhaya, lunikeza amandla, ukumelana nokushisa, kanye nokuqina okudingekayo ukugcina izakhiwo ziphephile futhi zisebenza kahle. Ububanzi balo bokusetshenziswa, ukusebenza kahle kwezindleko, kanye nokulula kokusetshenziswa kwenza kube ukukhetha okuphezulu kochwepheshe kanye nabantu abasebenza ngokuzenzela izinto zabo kuzo zonke izimboni. Uma uhlela iphrojekthi yokushisa okuphezulu, unganeliseki ngodaka oluvamile—tshala imali kudaka oluyi-clay refractory futhi uqinisekise ukuthi umsebenzi wakho uhlala isikhathi eside.
