Ezindaweni zezimboni lapho amazinga okushisa aphezulu, ingcindezi, kanye nezinto ezigugayo zinzima khona, izixazululo ezinokwethenjelwa zibalulekile.Izitini ze-SillimaniteZivelele "njengezisebenzi zezimboni," ezinezakhiwo ezivelele ezithuthukisa ukusebenza kahle, zinciphise izindleko, futhi zithuthukise ikhwalithi yomkhiqizo kuyo yonke imboni yensimbi, izinto zobumba, kanye nokukhiqizwa kwengilazi. Nasi isizathu sokuthi ziyisinqumo esiphezulu emhlabeni jikelele.
1. Izakhiwo Eziyinhloko: Yini Eyenza Izitini Ze-Sillimanite Zibaluleke Kakhulu
Lezi zitini zitholakala ku-aluminosilicate mineral sillimanite, zinikeza izinzuzo ezintathu ezingenakuqhathaniswa:
Ukuqina Kokugqama Okuphezulu Kakhulu:Njengoba izinga lokuncibilika lingaphezu kuka-1800°C, ziyamelana nokushisa okukhulu (okubalulekile ekuncibilikiseni insimbi kanye nokuncibilika kwengilazi, lapho amazinga okushisa edlula khona u-1500°C) ngaphandle kokugoba noma ukonakala.
Ukwanda Okuphansi Kokushisa:Izinga elingaphansi kuka-1% ku-1000°C livimbela ukuqhekeka ekushaqekeni kokushisa, okuqinisekisa ukuqina ezindaweni ezifudumezayo nezipholile njengezibhamu zokuqhuma.
Ukumelana Okuphakeme:Ziqinile futhi ziqinile, zimelana nokuguguleka okuvela ezinsimbini ezincibilikisiwe/ukubola kanye nokuguguleka kwamakhemikhali okuvela kuma-asidi/ama-alkali—okuyisihluthulelo sokucubungula amakhemikhali kanye ne-metallurgy.
Lezi zici ziguqula izitini ze-sillimanite zibe "ezinhle okufanele ube nazo" zibe "ezifanele ube nazo" ukuze kusebenze kahle.
2. I-Metallurgy: Ukuthuthukisa Ukukhiqizwa Kwensimbi Nensimbi
Imboni yensimbi ithembele kakhulu ezitini ze-sillimanite ukuze isetshenziswe imishini ecindezelwe ukushisa:
Ama-Blast Furnace Linings:Njengoba zimboze "indawo eshisayo" (1500–1600°C) yezitofu ezikhiqiza insimbi, zidlula izitini zomlilo zendabuko. Isitshalo sensimbi saseNdiya siphile isikhathi eside ngo-30% kanye nezindleko zokulungisa eziphansi ngo-25% ngemva kokushintsha.
Ama-Linings aseTundish kanye neLadle:Ukunciphisa ukungcola kwensimbi nokwandisa isikhathi sokuphila kwendwangu ngamaphesenti afinyelela ku-40 (ngomenzi wensimbi waseYurophu), kuqinisekisa ukuphathwa kwensimbi encibilikisiwe okubushelelezi.
Izitsha Zokususa I-sulfur:Ukumelana kwazo ne-slag egcwele isibabule kugcina ukuhambisana, kusiza ukuhlangabezana nezindinganiso eziqinile zokuhlanzeka kwensimbi.
Kwabochwepheshe bezinsimbi, izitini ze-sillimanite ziyindlela yokutshala imali ebaluleke kakhulu ekukhiqizeni.
3. Izinto zobumba: Ithayela Lokukhulisa, Izinto Zokuhlanza kanye Nezinto Zobumba Zobuchwepheshe
Kuzinto zobumba, izitini ze-sillimanite zifeza izindima ezimbili ezibalulekile:
Ama-Linings e-Kiln:Ukugcina ukushisa okufanayo (kufika ku-1200°C) ezitsheni zokushisa, ukunwebeka kwazo okuphansi kuvimbela umonakalo. Umkhiqizi wamathayili waseShayina unciphise izindleko zamandla ngo-10% ngemuva kokulungiswa kabusha, ngokusetshenziswa kwamandla okuphansi ngo-15–20%.
Okungeziwe kwezinto ezingavuthiwe:Kugaywe kube yimpuphu (5–10% ezixubeni), kwandisa amandla okusebenza (amandla okuguquguquka aphezulu ngo-25%) kanye nokuzinza kokushisa (umonakalo wokushaqeka ongaphansi kuka-30% kokushisa) ezintweni zobumba zobuchwepheshe.
4. Ukukhiqizwa Kwengilazi: Ukulinganisela Ikhwalithi Nezindleko
Izitini ze-sillimanite zixazulula izinselele ezibalulekile zokukhiqiza ingilazi:
Izinto Zokuvuselela Izitofu:Njengoba zikwazi ukuvuselela izinto ezibamba ukushisa, ziyamelana nokuqhekeka kanye nokungena komhwamuko wengilazi. Umkhiqizi waseNyakatho Melika ubone impilo yezitini ende yeminyaka emibili, enciphisa izindleko zokufaka esikhundleni ngo-$150,000 ngesitofu ngasinye.
Ingilazi Ekhethekile:Njengoba zingaphansi kuka-0.5% we-iron oxide, zigwema ukungcolisa ingilazi ye-optical noma ye-borosilicate, okuqinisekisa ukucaca kanye nokuqina kwamakhemikhali ezikrinini ze-labware noma ze-smartphone.
5. Izimboni Zamakhemikhali Nezinye: Ukusingatha Izimo Ezinzima
Ukucubungula Amakhemikhali:Njengoba zimboze ama-reactor ashisa kakhulu, zivimbela ukuvuza futhi zandisa isikhathi sokuphila kwemishini—okubalulekile ekuphepheni komanyolo, uphethiloli, noma ukukhiqizwa kwemithi.
Ukushiswa kwemfucuza:Zimelana nokushisa okungu-1200°C kanye nokuguguleka kwemfucuza, zinciphisa ukugcinwa kwezitshalo ezisebenzisa imfucuza zibe amandla.
Khetha Izitini ze-Sillimanite ukuze Uphumelele Isikhathi Eside
Kungakhathaliseki ukuthi ungumenzi wensimbi, umkhiqizi we-ceramic, noma umkhiqizi wengilazi, izitini ze-sillimanite ziletha imiphumela. Inhlanganisela yazo eyingqayizivele yokumelana nokuqina, ukunwebeka okuphansi, kanye nokumelana kuzenza zibe yisisombululo esingabizi kakhulu nesiguquguqukayo.
Ukulungele ukuthuthukisa? Xhumana nethimba lethu ukuze uthole isilinganiso esenziwe ngokwezifiso kanye nokusekelwa kobuchwepheshe. Ake sakhe ikusasa lezimboni elisebenza kahle kakhulu—ndawonye.
