Silicon nitride (SiC) ke lehlabathe la quartz, coke ea petroleum e nang le calcined (kapa coking ea mashala), slag ea lehong (tlhahiso ea nitride ea silicon e tala e hloka ho eketsoa letsoai) le lisebelisoa tse ling tse tala, ka setofo sa motlakase se futhumatsang mocheso o phahameng se tsoelang pele. Lesale la ho tiisa la Silicon nitride ke sehlahisoa sa nitride sa silicon se entsoeng ka thepa ea silicon carbide. Joale lits'ebetso tsa bohlokoa tsa carbide ea silicon e sintered reaction-sintered le litšobotsi tsa litiiso ke life?
Tšebeliso ea bohlokoa ea silicon carbide e sintering ea karabelo:
1. Tšebeliso ea indasteri ea lihlahisoa tsa tšepe ke tšebeliso ea ho hanyetsa mocheso oa silicon nitride, matla a phahameng, ho tsamaisa mocheso hantle, ho hanyetsa tšusumetso, ho futhumatsa ka mokhoa o sa tobang mochesong o phahameng, joalo ka setofo sa tanka. Terei ea setofo sa Rectifier, sele ea aluminium electrolytic, lesela la setofo se qhibilihang sa koporo, arc ea setofo sa phofo ea zinki, tube ea tšireletso ea thermocouple, jj.
2. Tšebeliso ea indasteri ea tšepe e sebelisa ho betla ha silicon nitride. Ho hanyetsa mocheso, ho hanyetsa ho khohlela. Ka lebaka la ho tsamaisa mocheso hantle, e sebelisetsoa ho koahela lifono tse kholo le tse mahareng tsa ho etsa tšepe ho ntlafatsa bophelo ba ts'ebeletso.
3. Indasteri ea tšepe e sebelisang nitride ea silicon e sebelisa matla a silicon nitride, a latela tšepe ea khauta feela, a hanyetsa ho tsofala ho matla, a hanyetsa ho tsofala ho matla, a hanyetsa ho tsofala ho phahameng ha phaephe, impeller ea centrifugal, kamore ea pompo, mechini e potolohang, lesela la merafo, thepa e tala e loketseng, a hanyetsa ho tsofala ho hotle. Bophelo ba tšebeletso ea polasetiki ke makhetlo a 5 ho isa ho a 20, 'me ke e' ngoe ea thepa e tala e loketseng bakeng sa mabala a lipapali tsa lifofane.
4. Tšebeliso ea coefficient ea phetisetso ea mocheso boemong ba tlhahiso ea indasteri ea thepa ea moaho e khabisitsoeng ea porcelain le likotoana tsa lebili la lehlabathe. Litšobotsi tsa mocheso o khanyang le matla a feberu e phahameng, tlhahiso le tlhahiso ea onto ea tšepe ea lakane ha li fokotse feela bophahamo ba onto, empa hape li ntlafatsa bophahamo ba polokelo le boleng ba sehlahisoa sa onto, le ho fokotsa nako ea tlhahiso, e leng thepa e sa tobang e loketseng bakeng sa ho besa mebala ea letsopa.
5. Tšebeliso ea tšireletso ea tikoloho le boemo ba ho boloka matla e na le conductivity e ntle ea mocheso le khanyetso ea mocheso, 'me mochine o fapanyetsanang mocheso o boloka 20%, tšebeliso ea mafura 20%, tšebeliso ea mafura 35%,' me katleho ea tlhahiso e eketseha ka 20-30%. Haholo-holo, khanyetso ea ho tsofala ha phaephe ea phepelo ea metsi e sebelisoang fekthering ea ho sebetsa merafong e makhetlo a 6 ho isa ho a 7 ho feta thepa e tloaelehileng ea tšepe e kopaneng.
Likarolo tsa lesale la tiiso la silicon carbide e entsoeng ka karabelo:
1, ho hanyetsa mocheso
Ka lebaka la litšobotsi tsa thepa ea silicon nitride, litiiso tsa silicon nitride li na le khanyetso e phahameng ea mocheso, 'me lits'ebetso tse fapaneng li na le mefuta e fapaneng ea litšobotsi tsa khanyetso ea mocheso. Litiiso tsa silicon nitride tse sintered reaction-sintered li ka sebelisoa ho tloha likhatong tse 1300, 'me litiiso tsa silicon nitride tse se nang khatello li ka fihla likhatong tse 1600.
2. Khanyetso ea ts'enyeho
Lesale la ho tiisa la silicon nitride le ka sebelisoa ho tsoa ho acid e matla le alkali, 'me phello ea ho tiisa ha e bonolo ho e fokotsa.
3, ho hanyetsa ho tsofala
Masale a tiiso a silicon carbide a sintered ka karabelo ho latela ts'ebetso e itseng ea karete, e le hore moralo o nepahale haholo ebile o boreleli, hammoho le khanyetso ea ho tsofala ha thepa ea silicon carbide, masale a tiiso a silicon nitride a ka sebelisoa ho hohlana. Litšobotsi tse tsoelang pele tsa mocheso o phahameng ha li fokotse litšobotsi tsa tšenyo habonolo.
4. Bokgoni ba ho sebetsa
Reactivity sintered silicon carbide thepa e tala hafeela ho na le theknoloji e itseng ea ho e lokisa, e ka fetoloa mefuta e fapaneng ea lipaterone tsa ulu embryo, ts'ebetso ea bobeli, ho etsa hore bareki ba batle thepa.
