Uma kukhulunywa ngezindawo ezinezinga lokushisa eliphezulu—kusuka eziko ezimbonini kuya eziko zokuhlala—into eyodwa igqama njengomgogodla wobuqotho besakhiwo:udaka lwe-clay refractory. Njengoba iklanyelwe ukumelana nokushisa okwedlulele, ukuguguleka kwamakhemikhali, nokushaqeka okushisayo, lolu daka olukhethekile lungaphezu nje “kokunamathelisa” ezitini ezibambayo. Kuyingxenye ebalulekile eqinisekisa ukuphepha, ukusebenza kahle, nokuphila isikhathi eside lapho udaka olujwayelekile lungabhidlika. Kungakhathaliseki ukuthi usemsebenzini wokukhiqiza, wokwakha, noma ukuthuthukiswa kwekhaya le-DIY, ukuqonda ukusetshenziswa nezinzuzo zodaka lwe-clay refractory kungaguqula amaphrojekthi akho ezinga lokushisa eliphezulu.
Okokuqala nokubaluleke kakhulu, izithando zomlilo zezimboni kanye namahhanisi ayinkundla yokudlala eyinhloko yodaka lobumba. Ezigayweni zensimbi, ezimbonini zengilazi, ezimbonini zikasimende, nasezindaweni zokukhiqiza ze-ceramic, iziko lisebenza emazingeni okushisa angaphezu kuka-1,000°C (1,832°F) amahora noma ngisho nezinsuku ekugcineni. Udaka lukasimende oluvamile lwase-Portland luyancibilika noma lubole ngalezo zikhathi ezeqisayo, okuholela ekuhlulekeni kwesakhiwo, ukuvuza, kanye nesikhathi esimba eqolo. Udaka lwe-clay refractory, nokho, lwakhiwe ngobumba oluhlanzeke kakhulu, i-silica, nezinye izinhlanganisela eziphikisayo ezigcina amandla azo ebhondi kanye nokuma kulawa mazinga okushisa ashubile. Ivala izikhala phakathi kwezitini eziphikisayo, ivimbele ukulahlekelwa ukushisa okunganciphisa ukusebenza kahle kwamandla kuze kufike ku-30%. Kubasebenzi bezimboni, lokhu kuhumushela ekwehliseni izikweletu zamandla, iziphazamiso ezimbalwa zokulungisa, kanye nokuhambisana nezindinganiso eziqinile zokuphepha.
Ngaphandle kwemboni enzima, udaka lwe-clay refractory luyisisekelo sezinhlelo zokufudumeza ezentengiselwano nezokuhlala. Iziko, izitofu zokubasa izinkuni, namalayini kashimula athembele kuwo ukuze enze umgoqo ovikelekile, ongashisi. Ake ucabange ukokhela umlilo othokomele egumbini lakho lokuphumula ukuze nje udaka olubambe izitini zakho zomlilo luqhekeke futhi lukhiphe intuthu enobuthi—lena ingozi yokusebenzisa udaka olunganqamuki. Udaka lwe-clay refractory alugcini nje kuphela ukumelana nomjikelezo wokushisisa nokupholisa wezindawo zokuhlala kodwa futhi lumelana nezinto ezigqwalayo zezinkuni ezivuthayo noma zamalahle. Kulula ukuhlanganisa nokufaka isicelo, okuyenza ibe inketho ephezulu yabamashi abangochwepheshe nabathanda i-DIY ngokufanayo. Abanikazi bezindlu abatshala imali eziko elisha noma belungisa endala bazothola ukuthi ukusebenzisa udaka lwe-clay refractory kuqinisekisa ukuthi isici sabo sokushisa sihlala amashumi eminyaka ngaphandle kokubeka engcupheni ukuphepha.
Esinye isicelo esiyinhloko yizinqubo ze-petrochemical kanye ne-metallurgical. Izikhungo zokucwenga, izincibilikisi, nezindawo ezisekelwe kuzo azihlanganisi nje izinga lokushisa eliphezulu kuphela kodwa namakhemikhali anonya—ama-asidi, ama-alkali, nezinsimbi ezincibilikisiwe ezingacekela phansi udaka oluvamile. I-Clay refractory mortar`s chemical inertness iyenza ilungele imikhumbi yokusabela kolwelwesi, ama-crucible, namasistimu wokukhipha umoya. Kwakha uphawu oluqinile oluvimbela ukuvuza kwezinto eziyingozi, ukuvikela abasebenzi kanye nemvelo. Ekuncibilikiseni i-aluminiyamu, isibonelo, udaka lwe-clay refractory lusetshenziselwa umugqa wamaseli e-electrolytic, lapho lumelana nokugqwala okuvela ku-aluminium encibilikisiwe nosawoti we-fluoride. Lokhu kwethembeka yingakho kuyinketho ekhethwayo ezimbonini lapho ukwehluleka okuncane kakhulu kungaba nemiphumela eyinhlekelele.
Udaka lwe-clay refractory nalo ludlala indima ebalulekile kuhhavini we-pizza nasekhishini lezentengiselwano. Amahhavini e-pizza abaswa ngokhuni asebenza emazingeni okushisa aphakathi kuka-400°C no-500°C (752°F no-932°F), adinga udaka olukwazi ukumelana nokushisa okukhulu ngaphandle kokuqhekeka noma ukulahlekelwa ukunamathela. Ama-pizzeria angochwepheshe nabapheki basekhaya ngokufanayo bathemba udaka lobumba lobumba ukuze bakhe futhi balungise lawa mahhavini, njengoba kuqinisekisa ukusatshalaliswa kokushisa okungaguquki futhi kuvimbele intuthu noma ukushisa ukuthi kungaphumi. Ekhishini lezentengiselwano, isetshenziselwa ukuhlanganisa ama-grill, ama-rotisseries, nezinye izinto zokusebenza ezishisa kakhulu, igcina izindinganiso zokuhlanzeka ngokuvimbela izinhlayiya zokudla ukuthi zingabambeki odakeni oluqhekekile.
Yini eyenza udaka lwe-refractory luhluke kwezinye izinto eziphikisayo? Ukuguquguquka kwayo nokusebenza kahle kwezindleko. Ngokungafani ne-alumina ephezulu noma udaka lwe-silica, ezidizayinelwe amazinga okushisa aphakeme kakhulu kodwa eza nethegi yentengo ephezulu, ukusebenza kwebhalansi yodaka lwe-clay refractory kanye nokuthengeka kwezinhlelo zokusebenza ezivamile zokushisa okuphezulu. Itholakala ngendlela eyimpushana, engaxutshwa namanzi esizeni ukuze ilingane ngendlela oyifunayo, kwehliswe imfucuza kanye nezindleko zokuhamba. Ukwengeza, iyakwazi ukusebenza kahle kakhulu—abamashi bangakwazi ukuyilolonga kalula futhi bayishelele, baqinisekise isibopho esiqinile phakathi kwezitini.
Ukukhetha udaka olufanele lwe-clay refractory kubalulekile ukuze iphrojekthi yakho iphumelele. Bheka imikhiqizo ehlangabezana nezindinganiso zomkhakha, njenge-ASTM C199, ecacisa izidingo zodaka oluphikisayo. Cabangela izinga lokushisa eliphezulu lohlelo lwakho lokusebenza, njengoba ezinye izinsimbi zobumba zenzelwe izigaba zokushisa eziphakeme kunezinye. Kumaphrojekthi ezimboni, khetha udaka olunezithasiselo ezithuthukisa ukumelana nokushaqeka okushisayo kanye nokuzinza kwamakhemikhali. Ukuze kusetshenziswe indawo yokuhlala, udaka olujwayelekile lwe-clay refractory luzokwanela ezindaweni eziningi zomlilo nezitofu.
Sengiphetha, udaka lwe-clay refractory luyinto ebaluleke kakhulu kunoma yisiphi isicelo esibandakanya amazinga okushisa aphezulu. Kusukela eziko ezimbonini kuya eziko zasekhaya, inikeza amandla, ukumelana nokushisa, nokuqina okudingekayo ukuze kugcinwe izakhiwo ziphephile futhi zisebenza kahle. Ukusetshenziswa kwayo okubanzi, ukusebenza kahle kwezindleko, kanye nokusebenziseka kalula kuyenza ibe ukukhetha okuphezulu kochwepheshe kanye nama-DIYers kuzo zonke izimboni. Uma uhlela iphrojekthi yokushisa okuphezulu, ungahlali endaweni evamile - tshala udaka lwe-clay refractory futhi uqinisekise ukuthi umsebenzi wakho uvivinya isikhathi.
