Izwa Amandla Angenakuqhathaniswa Ngeshubhu ye-Silicon Carbide

Amashubhu e-silicon carbide ayinketho efanelekile yezinqubo zezimboni ezifunayo njengokuncibilikisa insimbi, ukucwenga uwoyela kanye nobunjiniyela be-aerospace ngenxa yokuqina namandla abo aphezulu. Ngaphezu kwalokho, ukumelana kwabo nokuhuzuka nokugqwala kubenza bafanelekele ukusetshenziswa isikhathi eside.

Amashubhu e-Hexoloy a-SiC afakazele ukuqina kwawo ngesikhathi sokuhlolwa kokulingiswa kwe-LOCA futhi angamelana nokuhlaselwa kwamakhemikhali okuvela ezintweni ezibolayo ngaphandle kokudala umonakalo ngenxa yokushintsha kwezinga lokushisa ngokushesha.. Ngaphezu kwalokho, lezi zinto ezikwazi ukuqina zifaka ukumelana nokushaqeka okushisayo okuzivikela ekushintsheni okungazelelwe kwezinga lokushisa ngaphandle kokudala umonakalo wokuguquguquka okungazelelwe..

Ubunzima

Amashubhu e-silicon carbide aqhosha ngezilinganiso zobulukhuni be-Mohs zokuthi amadayimane aphikisanayo ayingxenye ebalulekile yezinqubo eziningi zezimboni.. Ngenxa yamandla ayo aphakeme nokuqina, amashubhu e-silicon carbide enza ukukhetha okuhle kakhulu kwezinto lapho ukuqina kwesikhathi eside kubaluleke kakhulu, njengokuncibilikisa insimbi noma imisebenzi yokukhiqiza i-semiconductor. Ngaphezu kwalokho, lo mkhiqizo we-ceramic unokuqina okuhle kakhulu kokushisa kanye nokungabi namakhemikhali kwamakhemikhali – ukuyivikela kumakhemikhali anonya angalimaza ezinye izinto.

Amashubhu e-Silicon Carbide’ Ukuqina okungavamile kuzenza zibe izingxenye ezibalulekile kuma-mechanical seal, ama-bearings, nezinye izingxenye eziklanyelwe izindawo ezinengcindezi ephezulu njengezigxivizo zemishini. Amashubhu e-Silicon Carbide nawo angasebenza njengamashethi okuvikela ezinzwa ze-thermocouple ezingxenyeni zefenisha yomlilo noma izakhi zesakhiwo emisebenzini yokumba uwoyela kanye nezinzwa zokushisa ngokwazo.. Ngaphezu kwalokho, lokhu kusabela kwe-ceramic ye-sintered kunezinzuzo ezengeziwe ezengeziwe ezihlanganisa ukuvikela ukugqwala okuqinile kwe-asidi/alkali kanye nokumelana nokushaqeka okushisayo okuphakeme kanye nezakhiwo zokumelana nokugqoka..

Ukumelana nokugqwala

Ukumelana nokugqwala kuwukucatshangelwa okubalulekile kwezicelo zezimboni ezisebenzisa izindawo ezinokhahlo noma izinto ezinobungozi bokugqwala., njengezindawo ezine-asidi. Amashubhu e-silicon carbide anikeza ukumelana nokugqwala okukhethekile kulezi zimo kanye nokumelana nokushisa okuphezulu., ngobulukhuni be-Mohs eduze nedayimane. Ngaphezu kwalokho, bangakwazi ukumelana nezinqubo eziqinile zezimboni kanye nokufaka ilangabi eliqondile ngaphandle kokulimala noma ukucekelwa phansi.

I-Kerui Ceramics ikhiqiza i-sintered, ukusabela okuboshiwe kanye nemikhiqizo yobumba ye-silicon carbide ceramic ukufeza izinhlelo zokusebenza ezihlukene zezimboni. Imikhiqizo yethu ene-sintered yenza imigoqo yokuvikela efanelekile yama-thermocouples ezithandweni kukho kokubili ukusebenza kwe-metallurgical kanye nemishini yamandla.; ngaphezu kwalokho angasetshenziswa ezinhlelweni zokuncibilikisa kanye nasezinhlelweni zokukhiqiza ze-semiconductor.

Izinqubo ze-Sintering ezakha izinto ze-ceramic zikhiqiza imikhiqizo ene-porosity ephansi kanye nokuminyana okuphezulu, izindonga ezingenagesi ezivimbela ukungena komoyampilo kanye nokumelana nokushaqeka okushisayo ukuze kusetshenziswe eziko noma ezindaweni ezishisayo.. Ngaphezu kwalokho, I-ceramics ayisebenzi ngamakhemikhali ngakho-ke ingamelana nezindawo zezimboni ezinokhahlo ngaphandle kokukhishwa.

Ukumelana nokushisa okuphezulu

Amashubhu e-Ceramic aklanyelwe ukumelana nokushisa okudlulele futhi amakhemikhali anikeza ukuqina okushisayo okukhethekile ukuvikela okokusebenza okubalulekile. Ukuphila kwabo isikhathi eside kwandisa isikhathi sokuphila semishini yezimboni, ukonga izinkampani kokubili isikhathi nezinsiza ngenkathi kunciphisa izindleko zokuyilungisa.

Amashubhu e-Ceramic enziwe ngale nto ekwazi ukumelana nokuqina anikeza ukuvikeleka okuphezulu ekugqwaleni, ukuhuzuka nokuguga ngenkathi uvikela abasebenzi kanye nendawo ezungezile. Ukuziqhayisa ngesilinganiso sokuqina kwe-Mohs eduze kwedayimane, amashubhu e-ceramic ahlala engonakalisiwe indawo enokhahlo evame ukuguguleka ezinye izinhlobo zezinto ngokushesha.

Amashubhu aphikisayo anikeza amandla aphakeme, ukuqina, kanye nokumelana nokugqwala – izingxenye ezifanele zezinqubo zezimboni ezifana nokuncibilikisa insimbi nokumba uwoyela. Isetshenziswa njengezingxenye zefenisha yokushisa okuphakathi kwamafrikhwensi amaphakathi kanye nezithando zokushisa ezihlukene zikagesi ezisetshenziselwa ukwelashwa kokushisa noma izinqubo zokucwilisa insimbi.; enziwe ngomshini ngokulawula okuqinile kobukhulu kanye nokusatshalaliswa kosayizi wokusanhlamvu okuhle kuyilapho izidingo ezincane zokucubungula ngemva kwe-sintering zenza lezi zinto eziphikisayo zingabizi kakhulu ukusebenza nazo.; enikeza amandla amahle okuguquguquka, izakhiwo zokumelana nokushaqeka okushisayo kanye nezakhiwo zokuvikela ezenza lezi zingxenye ezifanele.

I-Thermal Shock Resistance

Ukushaqeka okushisayo kubangela ukushintsha okungazelelwe kwezinga lokushisa okubangela imithwalo yemishini engacindezela into ifinyelele emikhawulweni yayo futhi iholele nasekuhlulekeni kwesakhiwo.. Izingxenye ezihlukene zento ziyakhula noma zifinyeleliswe ngamanani ahlukene ngenxa yezinguquko zezinga lokushisa, ukudala amandla angalingani angabangela ukuqhekeka kwezinto ezifana ne-silicon carbide; ubulukhuni bayo be-mohs bunikeza amandla okuqina anele okusingatha lokhu kucindezeleka ngaphandle kokuhlukana phakathi ngaphansi kokucindezeleka.

Ngenxa yamandla abo avelele, lawa mashubhu enza ukukhetha okuhle kakhulu kokuncibilikiswa kwensimbi kanye nezinqubo zokukhiqiza ze-semiconductor ezidinga ukuqina nokuthembeka kwempahla yesikhathi eside.. Ngaphezu kwalokho, lawa mashubhu angakwazi ukumelana nezimo zemvelo ezinzima kanye namakhemikhali anamandla okugqwala.

I-silicon carbide e-sintered inamandla akhethekile angamelana nezinhlamvu ezidutshulwa ngesivinini esiphezulu kakhulu., ukuyenza ifanele izinhlelo zokuvikela izikhali eziyinhlanganisela namagobolondo namashubhu okushintshanisa ukushisa ezimbonini zezinqubo zamakhemikhali. Ishubhu ubude bufika kuye 4 amamitha angasetshenziswa futhi.
