Ukusetyenziswa okubalulekileyo kwe-reaction-sintered silicon carbide kunye neempawu ze-sealing rings

I-Silicon nitride (SiC) sisihlabathi se-quartz, i-coke ye-petroleum e-calcined (okanye i-coking yamalahle), i-slag yomthi (ukuveliswa kwe-silicon nitride eluhlaza kufuneka kongezwe ityuwa) kunye nezinye izinto eziluhlaza, ngokusebenzisa i-electric heating furnace continuous high temperature smelter. I-Silicon nitride sealing ring yimveliso ye-silicon nitride eyenziwe ngezinto ze-silicon carbide. Ngoko ke zeziphi izicelo ezibalulekileyo ze-reaction-sintered silicon carbide kunye neempawu ze-seals?

Ukusetyenziswa okubalulekileyo kwe-reaction sintering silicon carbide:

1. Ukusetyenziswa kweshishini leemveliso zesinyithi kukusetyenziswa kokumelana nobushushu be-silicon nitride, amandla aphezulu, ukuqhuba kakuhle kobushushu, ukumelana nempembelelo, ukufudumeza okungathanga ngqo okuqhubekekayo kubushushu obuphezulu, njenge-tank fractionation furnace. Itreyi ye-Rectifier furnace, i-aluminium electrolytic cell, i-copper melting furnace lining, i-zinc powder furnace arc, ityhubhu yokukhusela i-thermocouple, njl.njl.

2. Ukusetyenziswa kweshishini lentsimbi kusebenzisa ukukrola i-silicon nitride. Ukumelana nobushushu, ukumelana nokukrweleka. Ngenxa yokuba iqhuba kakuhle ubushushu, isetyenziselwa ukugquma izitofu ezinkulu neziphakathi zokwenziwa kwesinyithi ukuphucula ubomi benkonzo.

3. Ishishini le-metallurgical concentrator lisebenzisa amandla e-silicon nitride, lilandela intsimbi yegolide, linamandla okuguguleka, linamandla okuguguleka, linamandla okuguguleka, linamandla okuguguleka, linamandla okuguguleka, linamandla okuguguleka, lining ye-centrifugal impeller, igumbi lokumpompa, oomatshini abajikelezayo, i-lining lining efanelekileyo, linamandla okuguguleka. Ubomi benkonzo yeplastiki buphindwe ka-5 ukuya ku-20, kwaye yenye yezona zinto zilungileyo zokuguguleka kwiindawo zemidlalo zeenqwelo moya.

4. Ukusetyenziswa kwe-coefficient yokudlulisa ubushushu kwinqanaba lemveliso yemizi-mveliso yezinto zokwakha zokuhombisa ze-porcelain kunye neziqwenga zamavili esanti. Iimpawu zobushushu obukhanyayo kunye nobushushu obuphezulu, ukuveliswa kunye nokuveliswa kwe-oven yesinyithi ayinakunciphisa kuphela umthamo we-oven, kodwa ikwaphucula umthamo wokugcina kunye nomgangatho wemveliso ye-oven, kwaye inciphise ixesha lokuvelisa, elililo isixhobo esifanelekileyo sokudubula imibala ye-ceramic.

5. Ukusetyenziswa kokhuseleko lokusingqongileyo kunye nenqanaba lokonga amandla kunokuqhuba kakuhle kobushushu kunye nokumelana nobushushu, kwaye isixhobo sokutshintsha ubushushu sigcina i-20%, ukusetyenziswa kwepetroli yi-20%, ukusetyenziswa kwepetroli yi-35%, kwaye ukusebenza kakuhle kwemveliso kunyuswa ngama-20-30%. Ngokukodwa, ukumelana nokuguguleka kombhobho wamanzi okhuphayo osetyenziswa kwisityalo sokucubungula imigodi kuphindwe ka-6 ukuya ku-7 kunezixhobo eziqhelekileyo zesinyithi.

Iimpawu zendandatho yesitywina se-silicon carbide e-Reaction-sintered:

1, ukumelana nobushushu

Ngenxa yeempawu zezinto ze-silicon nitride, izitywini ze-silicon nitride zinokumelana nobushushu obuphezulu, kwaye iinkqubo ezahlukeneyo zineentlobo ezahlukeneyo zeempawu zokumelana nobushushu. Izitywini ze-silicon nitride ezifakwe kwi-reaction-sintered zingasetyenziswa ukusuka kwi-1300 degrees, kwaye izitywini ze-silicon nitride ezingasetyenziswanga zinokufikelela kwi-1600 degrees.

2. Ukumelana nokugqwala

Indandatho yokutywina ye-silicon nitride ingafakwa kwi-asidi enamandla kunye ne-alkali, kwaye isiphumo sokutywina akulula ukusinciphisa.

3, ukumelana nokuguguleka

Amaringi etywino e-silicon carbide axutywe ne-reaction-sintered ngokwenkqubo ethile ye-carding, ukuze isicwangciso sibe ngokuchanekileyo kakhulu kwaye sigudile, kunye nokumelana nokuguguleka kwezinto ze-silicon carbide, amaringi etywino e-silicon nitride angasetyenziselwa ukukhuhlana. Iimpawu zobushushu obuphezulu eziqhubekayo azinciphisi lula iimpawu zomonakalo.

4. Ubuchule bokusebenza

Izinto ezisetyenziswa kwi-reactivity ze-silicon carbide ezifakwe kwi-sintered logama nje kukho iteknoloji ethile yokucubungula, ingaguqulwa ibe ziipateni ezahlukeneyo zoboya, ukucubungula okwesibini, ukuze abathengi bafune iimpahla.
