Bututun kariya na silicon carbide
A cikin masana'antu inda yanayi mai tsanani ke barazana ga ingancin kayan aiki,bututun kariya na silicon carbide (SiC)Ya bayyana a matsayin mafita mai ban mamaki. Ba kamar kayan kariya na gargajiya ba, bututun SiC suna haɗa kimiyyar kayan tarihi da injiniya mai ƙarfi don kare kayan aiki da matakai masu mahimmanci. Yana da fa'idodi masu zuwa:
1. Kariya mara misaltuwa a cikin Yanayi Mai Wuya
Bututun kariya na SiC suna aiki a matsayin layin farko na kariya a cikin muhalli inda gazawa ba zaɓi bane:
(1) Kariyar Zafi: Yana jure yanayin zafi mai ɗorewa har zuwa 1600°C, na'urori masu kariya, na'urorin thermocouples, ko na'urori masu bincike daga ƙarfe mai narkewa, harshen wuta, da kuma plasma.

Juriyar Tsabtace Kashi: Kare daga barbashi masu lalata a cikin gadaje masu ruwa, na'urorin gas na kwal, ko ayyukan haƙar ma'adinai.
2. Daidaito da Kwanciyar Hankali don Ma'auni Masu Muhimmanci
A cikin manyan ayyukan masana'antu, daidaito shine mafi mahimmanci. Bututun SiC suna ƙara aminci ta hanyar:
(1) Rage Tsangwama ga Sigina: Sifofin da ba sa aiki da wutar lantarki suna hana katsewar lantarki a cikin na'urori masu auna sigina na lantarki.
(2) Kwanciyar Hankali: Nauyin yanayin zafi kusan sifili yana tabbatar da daidaiton daidaito da daidaiton aunawa a ƙarƙashin saurin canjin zafin jiki.
(3) Ingancin Iskar Gas Mai Tauri: Tsarin da ba ya shiga cikin ruwa yana hana shigar iskar gas, wanda yake da mahimmanci ga tsarin injin ko yanayin da aka sarrafa.
3. Kunna bututun kariya na SiC Technologies na Gaba don buɗe sabbin abubuwa a fannoni masu tasowa:
(1) Tattalin Arzikin Hydrogen: Yana aiki azaman murfin kariya mai ɗorewa ga na'urori masu auna hydrogen, adanawa, da ƙwayoyin mai, yana tsayayya da bushewa da fallasa H₂ mai matsin lamba.
(2) Masana'antar Semiconductor: Kare na'urori masu auna gani da zafi a cikin na'urorin CVD (Sinadari Mai Tsabtace Tururi) daga abubuwan da suka fara lalata abubuwa kamar silane ko ammonia.
(3) Binciken Sararin Samaniya: Kariyar kayan aiki a cikin injunan roka da na'urorin bincike na duniya daga matsanancin yanayin zafi da hasken rana.
4. Ingantaccen Kuɗi Ta Hanyar Tsawon Rai
Duk da cewa bututun SiC suna da farashi mai girma a gaba, zagayowar rayuwarsu tana da fa'ida ta sake fasalta darajar:
(1) Rage Lokacin Da Ake Bukata: Sauran ƙarfe ko ma'aunin quartz da sau 4-6 a cikin saitunan abrasive ko acidic, wanda ke rage kulawa da ba a tsara ba.
(2) Bukatun Rufi Sifili: Ba kamar ƙarfe da ke buƙatar rufin kariya ba, halayen SiC na ciki suna kawar da farashin gyaran saman da ke dawowa.
(3) Sake Amfani: Ci gaba da zagayowar ayyuka da yawa a aikace-aikace kamar simintin ƙarfe ko ƙirƙirar gilashi ba tare da lalacewa ba.
5. Keɓancewa don Bukatu na Musamman
Bututun kariya na SiC sun dace da ƙalubalen da suka shafi fasaha ta hanyar injiniyan da aka keɓance:
(1) Tsarin Gauraya: Haɗa shi da ƙarfe ko yumbu don haɗa abubuwa masu aiki da yawa (misali masu haɗa zare, flanges).
(2) Gyaran Fuska: Kayan ciki masu gogewa don amfani da na'urar gani ko kuma kayan waje masu laushi don haɓaka fitar da zafi.
(3) Sauƙin Girma: An ƙera shi daga millimeters (ma'aunin injina na dakin gwaje-gwaje) zuwa mita (manyan murhun masana'antu).
6. Daidaito Mai Dorewa
Bututun SiC suna tallafawa ayyukan masana'antu masu dacewa da muhalli:
(1) Tanadin Makamashi: Ingantaccen amfani da zafi yana rage yawan amfani da man fetur a cikin tanda da kashi 20% idan aka kwatanta da garkuwar ƙarfe.
(2) Rage Sharar Gida: Tsawon rai yana rage sharar kayan da ake amfani da su akai-akai.
(3) Rage Guba: Kawar da buƙatar shafa mai haɗari (misali, ƙarfe masu tushen nickel) a cikin muhallin da ke lalata iska.
Kamfanin Shandong Zhongpeng Special Ceramics Co., Ltd yana ɗaya daga cikin manyan hanyoyin samar da sabbin kayan yumbu na silicon carbide a China. SiC technical yumbu: Taurin Moh shine 9 (taurin New Moh shine 13), tare da kyakkyawan juriya ga zaizayar ƙasa da tsatsa, kyakkyawan juriya - juriya da hana iskar shaka. Rayuwar sabis na samfurin SiC shine sau 4 zuwa 5 fiye da kayan alumina 92%. MOR na RBSiC shine sau 5 zuwa 7 na SNBSC, ana iya amfani da shi don siffofi masu rikitarwa. Tsarin ƙididdigewa yana da sauri, isarwa kamar yadda aka yi alkawari kuma ingancin ba shi da nasaba da komai. Kullum muna ci gaba da ƙalubalantar manufofinmu kuma muna mayar da zukatanmu ga al'umma.
