Ukuqina Okukhethekile Nge-Silicon Carbide Tube

I-Silicon Carbide (Site) Amashubhu anikela ngezicelo eziningi zezimboni zokusiza inkampani yakho izuze ukuqina okuhlukile. Ngenxa yamandla ayo ahlukile nokuphila isikhathi eside, Amashubhu we-SIC asebenza njengamandla anamandla ngemuva kwenqubekela phambili futhi abumba ikusasa lethu.

Izinto eziguquguqukayo ezinamandla aguquguqukayo afana nedayimane zingamelana nokucindezela okukhulu ngaphandle kokuqhekeka ngaphansi kwengcindezi, ukuziqhayisa ngokuqina kokuphuka okuhlaba umxhwele kanye nezakhiwo zokumelana namakhemikhali.

Amandla aphezulu

I-Silicon carbide iyinto eqinile futhi eqinile engamelana namazinga okushisa adlulele kanye nezindawo ezingalimaza izinto ezincane., kuyilapho amandla ayo emishini eyivumela ukuba imelane nokuhuzuka – okwenza kube ingxenye efanelekile ye-ceramic yezinhlelo zokusebenza ezidinga izinto eziqinile nezihlala isikhathi eside.

Ngokuqina kokuphuka okuphezulu (6.8 I-MPa m0.5) kanye ne-Young’s modulus (490 I-GPa), le nto ingamelana nezicelo zokucindezeleka okuphezulu kalula, kuyilapho ukuhanjiswa kwayo okushisayo kuvumela ukudluliswa kokushisa kahle kuyilapho kunciphisa izindleko zamandla zizonke zenqubo yakho.

Amashubhu e-Reaction sintered Silicon Carbide akhiqizwa ngokusebenzisa izinga lokushisa eliphezulu le-thermochemical reactions ehlanganisa i-silicon carbide powder ndawonye ibe yizinhlamvu eziminyene.. Lokhu kudala amandla aphezulu okugoba, ukumelana nokugqwala, ukungabi namakhemikhali kwamakhemikhali nokubekezelelana kwezinga lokushisa – ilungele amaziko kanye nabavikeli ababili abashisayo – kanye nezindleko ezincishisiwe zokulungisa nokulungisa okukongela imali ngokuhamba kwesikhathi. Ngaphezu kwalokho, imvelo yabo engasindi yenza ukufakwa kusheshe futhi kungabi nabuhlungu.

Ukumelana kahle kokugqwala okuhle

Amashubhu e-silicon carbide ceramic ayizinto ezikwazi ukumelana nokuqina, ukumelana nezindawo ezinokhahlo namakhemikhali anokonakala okuncane. Ubulukhuni bazo buphikisana nedayimane futhi bamelana nemihuzuko nokuguguleka kalula – izimfanelo ezibenza babe izingxenye ephelele izitshalo amandla.

Izinto ze-Ceramic zinamandla okumelana nezinga lokushisa elidlulele kanye nokuguquguquka kwengcindezi ngaphandle kokuphazamisa ubuqotho bazo besakhiwo.. Ukunwebeka kwazo okuphansi kokushisa kanye nokuguquguquka kokushisa okuphezulu kuzivumela ukuthi ziphendule ngokushesha futhi zivumelane kalula nokuguquguquka kwezinga lokushisa ngaphandle kokubeka engcupheni amandla noma ukuqina..

I-Silicon carbide inertness yamakhemikhali ikwenza kube ukukhetha okuhle kwempahla yeziko namanye amadivaysi ezimboni., enikeza ukumelana nokuhuzuka okungenakuqhathaniswa kanye nokuvikelwa ezindaweni ezinokhahlo namakhemikhali abolayo. Ukumelana kwayo ne-asidi kuza ngenxa yongqimba olumelana ne-asidi olwakhiwe phezu kwayo – ngokuqhubekayo ukuyivikela ezindaweni ezine-acidic – kuyilapho ukuzinza kwayo kobukhulu kanye nokumelana nokushaqeka okushisayo kwandisa ukuqina kwayo.

Ukungena kwamakhemikhali

I-Silicon Carbide iyinto ehlala isikhathi eside kakhulu enomzimba ophakeme, okomshini, izakhiwo ezishisayo namakhemikhali. Ngesilinganiso sobunzima be-Mohs 13 (ephakeme kunedayimane noma i-boron carbide), ubuqotho bayo besakhiwo kuvimbela ukuguquguquka ngaphansi kwengcindezi ngenkathi imelana nokugqwala kwamakhemikhali, ukuphakamayo, amazinga okushisa aphezulu kanye nokushaqeka kwezinga lokushisa kanye nokuba nesikhathi eside sokusebenza.

Ukuminyana kwe-SiC ye-Pressureless sintered kuhlala kufana emazingeni okushisa aphezulu futhi akukwazi ukungena ngegesi, ukuhlinzeka ngokuvikelwa ekuhlaselweni kwe-asidi nge-hydrochloric, i-sulfuric kanye ne-hydrobromic acid kanye nezisekelo, amakhemikhali e-oxidizing nezincibilikisi ezisetshenziswa ezimayini, ukuncibilika kwensimbi, izimboni zokucubungula insimbi nezihluza uwoyela.

Ngaphambi kokukhetha ibanga elifanele le-silicon carbide ceramic yohlelo lwakho lokusebenza, kubalulekile ukuhlola izimo zayo zokusebenza, imvelo ukugqwala kanye nezidingo mechanical. Lapho ukhetha ubude beshubhu yakho, ukujiya kodonga nobubanzi qiniseka ukuthi ingakwazi ukuphatha izingcindezi ezingokomzimba kanye nezindawo zamakhemikhali ekusetheni kwakho. Ngaphezu kwalokho, bheka abahlinzeki abahlinzeka ngezinto ezenziwe ngokwezifiso ukuze bahlangabezane nazo zonke izincazelo nezidingo zakho ezithile.

Ukuphila Okude

I-silicon carbide sekuyisikhathi eside ibhekwa njengento engavamile ngenxa yamandla ayo angavamile, ukumelana nokugqoka, Ukungena kwamakhemikhali, kanye nezakhiwo ezihlukile ze-thermal conductivity. Kodwa ukuxhaphaza ngokugcwele amandla ayo aphelele kudinga amasu okukhiqiza ochwepheshe kanye nezinqubo zokuphatha ezivela kubakhiqizi bayo.

Ubuchwepheshe be-Reaction sintering buvumela le nto ye-ceramic ukuthi iguqulwe isuka ku-silica-rich rich ibe yizingcezu ezicinene neziqinile ezingasetshenziswa ezinhlelweni eziningi.. Ifaka ubulukhuni be-Mohs obuqhathaniswa nedayimane, kanye nokumelana kakhulu nokuhlaselwa kwe-asidi njenge-nitric ne-hydrofluoric acid – okuyenza ibe inketho ekahle ezindaweni ezidinga ukumelana nokuhuzuka njengemishini yezimayini namabhobho enjini ye-aerospace.

Ngenxa yokwanda kwayo okushisayo okuphansi, I-ceramic fiber insulation iyinketho efanelekile yezinto ezibonakalayo ongazisebenzisa nama-thermocouples, ukuwavikela ekulimaleni noma ukuguga ngesikhathi sokusebenza. Ngaphezu kwalokho, ukugqwala kwayo- kanye nokumelana ne-oxidation kuyenza ifanelekele iziko lomhubhe noma izikebhe ze-shuttle.
