Silicon nitride (SiC) shi ne yashi ma'adini, calcined man coke (ko coal coking), itace slag (samar da kore silicon nitride bukatar ƙara gishiri) da sauran albarkatun kasa, ta hanyar lantarki dumama makera ci gaba da high zafin jiki smelter. Silicon nitride zoben rufewa shine samfurin siliki nitride wanda aka yi da kayan siliki na siliki. Don haka menene mahimman aikace-aikacen silicon carbide na amsawa-sintered da halayen hatimi?
Muhimmin aikace-aikacen amsawa sintering silicon carbide:
1. A aikace-aikace na karfe kayayyakin masana'antu ne da yin amfani da silicon nitride zafi juriya, high ƙarfi, mai kyau thermal watsin, tasiri juriya, m high zafin jiki kaikaitacce dumama albarkatun kasa, kamar tanki fractionation tanderu. Rectifier makera tire, aluminum electrolytic cell, jan narkewa tanderu rufi, tutiya foda makera baka, thermocouple kariya tube, da dai sauransu.
2. Aikace-aikacen masana'antar karfe yana amfani da etching na silicon nitride. Juriya girgiza zafi, juriya abrasion. Saboda kyawun yanayin zafi mai kyau, ana amfani da shi don liƙa manyan tanderun ƙarfe masu ƙarfi da matsakaici don haɓaka rayuwar sabis.
3. The metallurgical masana'antu concentrator masana'antu yana amfani da silicon nitride ƙarfi ne kawai na biyu zuwa zinariya karfe, karfi lalacewa juriya, shi ne mai karfi lalacewa juriya, high lalacewa juriya na bututun, centrifugal impeller, famfo dakin, Rotary inji, Mining rufi manufa albarkatun kasa, juriya mai kyau. Rayuwar sabis na filastik shine sau 5 zuwa 20, kuma yana ɗaya daga cikin ingantattun albarkatun ƙasa don filayen wasanni na jirgin sama.
4. A aikace-aikace na zafi canja wurin coefficient a cikin masana'antu samar matakin na ado ginin kayan ain da yashi dabaran guda. Halaye na radiant zafi da zafi tsanani tsanani, da samarwa da kuma masana'antu na sheet karfe kiln ba zai iya kawai rage kiln girma, amma kuma inganta ajiya girma da kuma samfurin ingancin kakin, da kuma rage samar lokaci, wanda shi ne manufa kai tsaye kai tsaye. abu don harbe-harbe na yumbu pigments.
5. Aikace-aikacen kariya ta muhalli da matakin ceton makamashi yana da kyakkyawan halayen thermal da juriya mai zafi, kuma mai amfani da zafi yana adana 20%, amfani da man fetur 20%, amfani da man fetur 35%, kuma aikin samar da ya karu da 20-30%. Musamman juriya na bututun samar da ruwa da ake amfani da su a masana'antar hakar ma'adinai ya ninka sau 6 zuwa 7 na kayan aikin ƙarfe na yau da kullun.
Fasalolin zoben hatimin siliki-carbide mai amsawa:
1, juriyar zafi
Saboda halaye na silicon nitride kayan, silicon nitride seals da high zafin jiki juriya, da kuma daban-daban matakai da daban-daban na zafi juriya halaye. Ana iya amfani da hatimin silikon nitride mai ɗaukar martani daga digiri 1300, kuma hatimin silikon nitride mara ƙarfi na iya kaiwa digiri 1600.
2. Juriya na lalata
Za a iya amfani da zoben rufewa na silicon nitride daga yanayin acid mai ƙarfi da alkali, kuma tasirin rufewa ba shi da sauƙin ragewa.
3, sanya juriya
Reaction-sintered silicon carbide hatimin zobba bisa ga wani tsarin carding, don haka da cewa shirin ne sosai daidai da santsi, haɗe tare da lalacewa juriya na silicon carbide kayan, silicon nitride hatimin zobe za a iya amfani da su shafa juna. Ci gaba da yanayin zafin jiki mai girma ba sa sauƙin rage halayen lalacewa.
4. Karfin hali
Reactivity sintered silicon carbide albarkatun kasa muddin akwai wasu fasahar sarrafawa, ana iya jujjuya shi zuwa nau'ikan nau'ikan amfrayo na ulu, sarrafa na biyu, don sa masu siye su so kaya.
