Ukusetyenziswa okubalulekileyo kwe-react-sintered silicon carbide kunye neempawu zokutywinwa kwamakhonkco

I-Silicon nitride (i-SiC) yintlabathi ye-quartz, i-coke ye-petroleum calcined (okanye i-coking coking), i-wood slag (ukuveliswa kwe-silicon nitride eluhlaza kufuneka idibanise ityuwa) kunye nezinye izinto eziluhlaza, ngokusebenzisa isinyibilikisi sombane sokufudumeza ngokuqhubekayo. Umsesane wokutywina we-silicon nitride yimveliso ye-silicon nitride eyenziwe ngezinto ze-silicon carbide. Ke zeziphi izicelo ezibalulekileyo ze-action-sintered silicon carbide kunye neempawu zamatywina?

Usetyenziso olubalulekileyo lwe-reaction sintering silicon carbide:

1. Ukusetyenziswa koshishino lweemveliso zetsimbi kukusetyenziswa kokumelana nobushushu be-silicon nitride, amandla aphezulu, ukuguquguquka okuhle kwe-thermal, ukuchasana nempembelelo, ubushushu obuqhubekayo obuphezulu obungangqalanga ukufudumeza izinto ezikrwada, ezifana ne-tank fractionation furnace. Itreyi yokuvuselela iziko, i-aluminium electrolytic cell, ubhedu olunyibilikisa isithando somlilo, i-zinc powder furnace arc, ityhubhu yokukhusela i-thermocouple, njl.

2. Ukusetyenziswa kweshishini lensimbi lisebenzisa i-etching ye-silicon nitride. Ukumelana nokothuka kobushushu, ukunganyangeki kwe-abrasion. Ngenxa yokuqhuba kakuhle kwe-thermal, isetyenziselwa ukuvala iziko lentsimbi enkulu kunye nobukhulu obuphakathi ukuze kuphuculwe ubomi benkonzo.

3. Umzi-mveliso we-metallurgical concentrator industry usebenzisa amandla e-silicon nitride ngowesibini kuphela kwintsimbi yegolide, ukuxhathisa okuqinileyo, ukuxhathisa okuqinileyo, ukumelana nokunxiba okuphezulu kombhobho, i-centrifugal impeller, igumbi lokumpompa, oomatshini abajikelezayo, i-mining lining efanelekileyo yezinto eziphathekayo, ukumelana nokunxiba kakuhle. Ubomi benkonzo yeplastiki ngamaxesha angama-5 ukuya kwangama-20, kwaye yenye yezinto ezifanelekileyo ezikrwada kumabala ezemidlalo eenqwelomoya.

4. Ukusetyenziswa kwe-coefficient yokudlulisa ubushushu kwinqanaba lemveliso yemveliso yezinto zokwakha ezihlobisa i-porcelain kunye neengcezu zevili lesanti. Iimpawu zobushushu obukhazimlayo kunye nobushushu obuphezulu bobushushu, ukuveliswa kunye nokuveliswa kwentsimbi yentsimbi ayinakunciphisa kuphela umthamo we-onti, kodwa nokuphucula umthamo wokugcina kunye nomgangatho wemveliso ye-oven, kunye nokunciphisa ixesha lokuvelisa, eyona nto ifanelekileyo ngokungathanga ngqo. izinto zokutshisa ii-pigments ze-ceramic.

5. Ukusetyenziswa kokhuseleko lokusingqongileyo kunye nenqanaba lokulondoloza amandla linomgangatho omhle we-thermal conductivity kunye nokumelana nokushisa, kwaye umtshintshi wokushisa ugcina i-20%, ukusetyenziswa kwe-fuel 20%, ukusetyenziswa kwe-fuel 35%, kunye nokusebenza kakuhle kwemveliso kunyuswe ngama-20-30%. Ngokukodwa, ukunyanzeliswa kokugqoka kombhobho wokunikezelwa kwamanzi okukhutshwa okusetyenziswa kwiplanti yokucubungula imigodi ngamaxesha angama-6 ukuya kwe-7 kwizinto eziqhelekileyo zentsimbi.

Iimpawu zokutywina ze-silicon carbide zokutywinwa kwe-reaction-sintered:

1, ukumelana nobushushu

Ngenxa yeempawu zezinto ze-silicon nitride, izitywina ze-silicon nitride zinokumelana nobushushu obuphezulu, kwaye iinkqubo ezahlukeneyo zineentlobo ezahlukeneyo zokumelana nobushushu. I-Reaction-sintered silicon nitride seals ingafakwa ukusuka kwi-1300 degrees, kunye ne-non-pressure calcined silicon nitride seals inokufikelela kwi-1600 degrees.

2. Ukumelana nokubola

Iringi ye-silicon nitride yokutywina ingafakwa kwi-asidi eyomeleleyo kunye nendalo yealkali, kwaye isiphumo sokutywinwa akulula ukunciphisa.

3, ukunxiba ukumelana

I-Reaction-sintered silicon carbide seal rings ngokwenkqubo ethile yamakhadi, ukuze isicwangciso sichaneke kakhulu kwaye sigudileyo, sidityaniswa nokunganyangeki kwezixhobo ze-silicon carbide, amakhonkco e-silicon nitride seal angasetyenziselwa ukukhuhlana. Iimpawu eziqhubekayo zokushisa okuphezulu azinciphisi ngokulula iimpawu zomonakalo.

4. Ukudubeka

I-reactivity sintered silicon carbide imathiriyeli ekrwada okoko nje kukho itekhnoloji yokusetyenzwa, inokuguqulwa ibe ziintlobo ngeentlobo zeepateni ze-embryo yoboya, ukusetyenzwa kwesibini, ukwenza abathengi bafune iimpahla.
