Silicon nitride (SiC) ke lehlabathe la quartz, calcined petroleum coke (kapa coking coking), lehong slag (tlhahiso ea silicon nitride e tala e hloka ho eketsa letsoai) le lisebelisoa tse ling tse tala, ka sebopi se futhumatsang sa motlakase se tsoelang pele mocheso o phahameng oa mocheso. Silicon nitride sealing ring ke sehlahisoa sa silicon nitride se entsoeng ka thepa ea silicon carbide. Joale ke lits'ebetso life tsa bohlokoa tsa reaction-sintered silicon carbide le litšobotsi tsa litiiso?
Tšebeliso ea bohlokoa ea karabelo sintering silicon carbide:
1. Ts'ebeliso ea indasteri ea lihlahisoa tsa tšepe ke tšebeliso ea silicon nitride mocheso ho hanyetsa, matla a phahameng, conductivity e ntle ea mocheso, ho hanyetsa tšusumetso, mocheso o tsoelang pele oa mocheso o sa tobang o futhumatsa lisebelisoa tse tala, tse kang sebōpi sa ho arohana ha tanka. Terei ea sebopi ea rectifier, sele ea aluminium electrolytic, lesela la sebopi le qhibilihang ka koporo, arc ea phofshoana ea zinc, tube ea ts'ireletso ea thermocouple, jj.
2. Tšebeliso ea indasteri ea tšepe e sebelisa etching ea silicon nitride. Ho hanyetsa mocheso oa mocheso, ho hanyetsa abrasion. Ka lebaka la ts'ebetso ea eona e ntle ea mocheso, e sebelisetsoa ho kenya libono tse kholo le tse mahareng tsa ho etsa tšepe ho ntlafatsa bophelo ba ts'ebeletso.
3. Indasteri ea concentrator ea metallurgic e sebelisa matla a silicon nitride ke ea bobeli feela ho tšepe ea khauta, ho hanyetsa ho roala ho matla, ho hanyetsa ho roala ho matla, ho hanyetsa liphaephe tse phahameng, centrifugal impeller, kamore ea pompo, mechine ea rotary, lisebelisoa tsa merafo tse loketseng, ho hanyetsa ho apara hantle. Bophelo ba tšebeletso ea polasetiki ke makhetlo a 5 ho isa ho a 20, 'me ke e' ngoe ea lisebelisoa tse loketseng bakeng sa mabala a lipapali a lifofane.
4. Tšebeliso ea mocheso o fetisang mocheso boemong ba tlhahiso ea indasteri ea lisebelisoa tsa ho haha porcelain le likotoana tsa lebili la lehlabathe. Litšobotsi tsa mocheso o khanyang le matla a phahameng a feberu, tlhahiso le tlhahiso ea sebōpi sa lakane ha se feela ho fokotsa molumo oa sebōpi, empa hape le ho ntlafatsa boleng ba polokelo le boleng ba sehlahisoa sa sebōpi, le ho fokotsa nako ea tlhahiso, e leng mokhoa o sa tobang o loketseng. lisebelisoa bakeng sa ho chesoa ha li-pigments tsa ceramic.
5. Tšebeliso ea ts'ireletso ea tikoloho le boemo ba ho boloka matla bo na le conductivity e ntle ea mocheso le ho hanyetsa mocheso, 'me mocheso oa 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 roala ha phala ea phepelo ea metsi e sebelisoang setsing sa ho sebetsa merafong ke makhetlo a 6 ho isa ho a 7 ho feta a lisebelisoa tse tloaelehileng tse kopantsoeng tsa tšepe.
Likarolo tsa selikalikoe sa silicon carbide seal rection-sintered:
1, ho hanyetsa mocheso
Ka lebaka la litšobotsi tsa lisebelisoa tsa silicon nitride, litiiso tsa silicon nitride li na le mocheso o phahameng oa ho hanyetsa, 'me mekhoa e fapaneng e na le mefuta e sa tšoaneng ea litšobotsi tsa ho hanyetsa mocheso. Litiiso tsa silicon nitride tsa Reaction-sintered li ka sebelisoa ho tloha ho likhato tse 1300, 'me litiiso tsa silicon nitride tse se nang khatello li ka fihla likhato tse 1600.
2. Ho hanyetsa kutu
Lesale la ho tiisa la silicon nitride le ka sebelisoa ho tsoa ho asiti e matla le tlhaho ea alkali, mme phello ea ho tiisa ha e bonolo ho fokotseha.
3, apara khanyetso
Reaction-sintered silicon carbide seal rings ho latela ts'ebetso e itseng ea likarete, e le hore moralo o nepahale haholo hape o boreleli, hammoho le ho hanyetsa ha thepa ea silicon carbide, mehele ea silicon nitride seal e ka sebelisoa ho hohlana. Litšobotsi tse tsoelang pele tsa mocheso o phahameng ha li fokotse habonolo litšobotsi tsa tšenyo.
4. Ductility
Reactivity sintered silicon carbide lisebelisoa tse tala ha feela ho na le theknoloji e itseng ea ho sebetsa, e ka fetoloa mekhoa e fapaneng ea boea embryo, ts'ebetso ea bobeli, ho etsa hore bareki ba batle thepa.
