Izinto Zokuqhuba Ezisebenza Kakhulu -- Ithusi leTellurium
Izici zomkhiqizo zethusi ye-tellurium
Ithusi leTellurium liyinto eyenziwe nge-alloy eyenziwe ngokungeza i-trace tellurium element ngesisekelo sethusi elimsulwa. Ukwengezwa kwe-tellurium kuthuthukisa kakhulu ukusebenza kokusika kwezinto, kuyilapho kugcinwa ugesi nokushisa okuhle kakhulu kwethusi. I-telluride yethusi inomoya wokudlulisa amandla angaphezu kuka-90% we-IACS kanye nomoya wokudlulisa amandla angaphezu kuka-350W/m·K, okwenza kube yinto efanelekile yokukhiqiza izingxenye ze-elekthronikhi ezinembile.
Ngokuphathelene nezakhiwo zemishini, ithusi le-tellurium libonisa amandla nobunzima obuhle kakhulu.
Amandla ayo okuthamba angafinyelela ngaphezu kwama-300MPa kanti ubulukhuni bungafinyelela kuma-80HB, okungcono kakhulu kunezinto ezivamile zethusi elihlanzekile. Ngesikhathi esifanayo, ithusi le-tellurium liphinde libe nokumelana okuhle nokuguguleka kanye nokumelana nokukhathala, okungahlangabezana nezidingo zokusetshenziswa isikhathi eside.
Ithusi leTellurium liphakeme kakhulu ngezakhiwo zokucubungula. Inkomba yalo yokusebenza kokusika ingafinyelela ngaphezu kuka-80%, okuphakeme kakhulu kune-alloy ejwayelekile yethusi. Lesi sici sithuthukisa kakhulu ukusebenza kahle kokukhiqiza futhi sinciphisa izindleko zokucubungula. Ngaphezu kwalokho, ithusi leTellurium liphinde libe nezakhiwo ezinhle zokushisela kanye nezakhiwo zokwelashwa kwendawo, okulula ukucutshungulwa okulandelayo.
Amapharamitha obuchwepheshe ethusi le-tellurium
Ukwakheka kwamakhemikhali okuvamile kwethusi le-tellurium kufaka phakathi: okuqukethwe kwethusi ≥99.5%, okuqukethwe kwe-tellurium 0.4-0.7%, kanti okunye kuyizinto ezilandelanayo. Lesi silinganiso sokwakheka esinembile siqinisekisa ukuzinza nokuvumelana kwezakhiwo zezinto.
Ngokuphathelene nezakhiwo zomzimba, ubuningi bethusi le-tellurium bungu-8.9g/cm³, iphuzu lokuncibilika lingu-1083℃, kanti i-coefficient yokwanda kokushisa ingu-17.0×10⁻⁶/℃. Lezi zinhlaka zinquma ukuqina kwayo kanye nokuthembeka kwayo ezindaweni zokushisa eziphakeme.
Amapharamitha empahla yemishini abonisa ukuthi amandla okukhiqiza ethusi le-tellurium angama-≥200MPa kanti ukunwebeka kungama-≥15%, okuqinisekisa ukuphepha nokuqina kwezinto ngesikhathi sokusetshenziswa.
Ukusetshenziswa kwethusi le-tellurium
Embonini kagesi neye-elekthronikhi, ithusi le-tellurium lisetshenziswa kabanzi ezixhumini, kuma-relay, kumaswishi nakwezinye izingxenye ezibalulekile. Ukuqhuba kwayo okuhle kakhulu kukagesi kanye nezakhiwo zokucubungula ziqinisekisa ukuthembeka nokuzinza kwemishini kagesi.
Embonini yezimoto, ithusi le-tellurium lisetshenziselwa ukwenza izingxenye ezifana nezinzwa, ama-terminal, nama-fuse. Ukumelana kwayo nokushisa okuphezulu kanye nokumelana nokugqwala kuhlangabezana nezidingo zendawo yokusebenza enzima yemoto.
Emkhakheni wezindiza, amandla aphezulu ethusi le-tellurium kanye nezakhiwo eziqhuba kahle kakhulu kwenza kube yinto ekhethwayo yokukhiqiza izinsimbi ezinembile namadivayisi kagesi. Ukuthembeka kwayo nokuqina kwayo kuqinisekisa ukusebenza okuphephile kwemishini yezindiza.
Ithusi le-Tellurium lidlala indima engenakuphindwa embonini yesimanje ngenxa yezakhiwo zalo ezinhle kakhulu eziphelele. Ngokuthuthuka kobuchwepheshe, insimu yokusetshenziswa kwethusi le-tellurium izoqhubeka nokukhula, inikeze ukwesekwa okuqinile kwezinto zokwakha ukuthuthukiswa kwezimboni ezahlukahlukene.
