Ukusetshenziswa okubalulekile kwe-silicon carbide e-reaction-sintered kanye nezici zokuvala izindandatho

I-Silicon nitride (SiC) iyisihlabathi se-quartz, i-coke ye-petroleum e-calcined (noma i-coking yamalahle), i-slag yokhuni (ukukhiqizwa kwe-silicon nitride eluhlaza okudingekayo ukwengeza usawoti) kanye nezinye izinto zokusetshenziswa, ngokusebenzisa i-smelter yokushisa kagesi eqhubekayo yokushisa okuphezulu. Indandatho yokuvala i-Silicon nitride iwumkhiqizo we-silicon nitride owenziwe ngezinto ze-silicon carbide. Ngakho-ke yiziphi izinhlelo zokusebenza ezibalulekile ze-silicon carbide e-reaction-sintered kanye nezici zezimpawu?

Ukusetshenziswa okubalulekile kwe-silicon carbide ekhipha ukusabela:

1. Ukusetshenziswa kwemboni yemikhiqizo yensimbi kusetshenziswa ukumelana nokushisa kwe-silicon nitride, amandla aphezulu, ukuqhuba kahle kokushisa, ukumelana nomthelela, izinto zokusetshenziswa zokushisa ezingaqondile eziqhubekayo ezishisayo, njengesithando somlilo esihlukanisayo. Ithreyi yesithando sokulungisa, iseli le-aluminium electrolytic, ulwelwesi lwesithando sokuncibilikisa ithusi, i-zinc powder furnace arc, ithubhu lokuvikela i-thermocouple, njll.

2. Ukusetshenziswa kwemboni yensimbi kusebenzisa ukuqoshwa kwe-silicon nitride. Ukumelana nokushaqeka kokushisa, ukumelana nokuklwebheka. Ngenxa yokuqhuba kwayo okuhle kokushisa, isetshenziselwa ukuhlanganisa izitofu ezinkulu neziphakathi zokuqhuma kwensimbi ukuze kuthuthukiswe impilo yesevisi.

3. Imboni ye-metallurgical concentrator isebenzisa amandla e-silicon nitride, angemva kwensimbi yegolide, angemva kokuguguleka okuqinile, angemva kokuguguleka okuqinile, angemva kokuguguleka okuphezulu kwepayipi, i-centrifugal impeller, igumbi lokupompa, imishini ejikelezayo, ulwelwesi lwezimayini, izinto zokusetshenziswa ezinhle kakhulu, angemva kokuguguleka okuhle. Isikhathi senkonzo yepulasitiki siphindwe ka-5 kuya ku-20, futhi singenye yezinto zokusetshenziswa ezifanele kakhulu ezinkundleni zemidlalo zezindiza.

4. Ukusetshenziswa kwe-coefficient yokudlulisa ukushisa ezingeni lokukhiqiza kwezimboni kwezinto zokwakha zokuhlobisa i-porcelain kanye nezingcezu zamasondo esihlabathi. Izici zokushisa okukhanyayo kanye nokushisa okuphezulu, ukukhiqizwa kanye nokukhiqizwa kwesitofu sensimbi esicwebezelayo akugcini nje ngokunciphisa umthamo wesitofu, kodwa futhi kuthuthukisa umthamo wokugcina kanye nekhwalithi yomkhiqizo wesitofu, futhi kunciphise isikhathi sokukhiqiza, okuyizinto eziqondile ezifanele zokushisa imibala ye-ceramic.

5. Ukusetshenziswa kokuvikelwa kwemvelo kanye nezinga lokonga amandla kunomoya omuhle wokushisa kanye nokumelana nokushisa, kanti i-heat exchanger igcina u-20%, ukusetshenziswa kukaphethiloli ku-20%, ukusetshenziswa kukaphethiloli ku-35%, kanye nokusebenza kahle kokukhiqiza kukhushulwa ngo-20-30%. Ikakhulukazi, ukumelana nokuguguleka kwepayipi lamanzi okukhipha elisetshenziswa esitshalweni sokucubungula izimayini kuphindwe izikhathi ezingu-6 kuya kwezingu-7 kunezinto ezivamile zensimbi ezihlanganisiwe.

Izici zendandatho yophawu lwe-silicon carbide e-Reaction-sintered:

1, ukumelana nokushisa

Ngenxa yezici zezinto ze-silicon nitride, izivalo ze-silicon nitride zinokumelana nokushisa okuphezulu, futhi izinqubo ezahlukene zinezinhlobo ezahlukene zezici zokumelana nokushisa. Izivalo ze-silicon nitride ezi-reaction-sintered zingasetshenziswa kusuka kuma-degrees angu-1300, kanti izivalo ze-silicon nitride ezi-non-pressure calcined zingafinyelela kuma-degrees angu-1600.

2. Ukumelana nokugqwala

Indandatho yokuvala ye-silicon nitride ingasetshenziswa kusukela esimweni se-asidi enamandla kanye ne-alkali, futhi umphumela wokuvala akulula ukuwunciphisa.

3, ukumelana nokuguguleka

Amasongo okuvala e-silicon carbide ahlanganiswe ne-reaction-sintered ngokwenqubo ethile yokubhala amakhadi, ukuze uhlelo lube luqondile kakhulu futhi lubushelelezi, luhambisana nokumelana nokuguguleka kwezinto ze-silicon carbide, amasongo okuvala e-silicon nitride angasetshenziswa ukuhlikihlana. Izici zokushisa okuphezulu okuqhubekayo azinciphisi kalula izici zomonakalo.

4. Ukuguquguquka

Izinto zokusetshenziswa ze-silicon carbide ezihlanganisiwe ze-reactivity inqobo nje uma kukhona ubuchwepheshe obuthile bokucubungula, zingaguqulwa zibe amaphethini ahlukahlukene e-embryo yoboya, ukucubungula kwesibili, ukuze abathengi bafune izimpahla.
