Usetyenziso Olutsha lweGreen Silicon Carbide Micropowder kwiShishini leCeramics
ULao Zhang usebenze kwi-ceramics kangangeminyaka engaphezu kwama-30. Intloko yakhe enkulu yayiyeyona iphambili yayikukuchaneka kwesivuno. Ukungalingani okuncinci kulawulo lobushushu ngexesha lokutshisa i-oven kunokubangela ukuqhekeka kunye nokuguquguquka kwemveliso. Kwiminyaka yakutshanje, umzi-mveliso wakhe uqalise ukusebenzisa izinto ezibizwa ngokuba yi-“i-micropowde ye-silicon carbide eluhlazar,” kwaye izinto zitshintshe kakhulu. “Kuyamangalisa ngokwenene,” utshilo. “Kufana nokongeza i-MSG kwisitya—iyandisa incasa kwaye igcina ulungelelwano.”
I-micropowder ye-silicon carbide eluhlaza yi-powder eluhlaza ecolekileyo kakhulu enobunzima obuphezulu, ukumelana nobushushu obuphezulu, kunye neempawu zeekhemikhali ezizinzileyo kakhulu. Ekuqaleni yayisetyenziselwa ikakhulu izinto ezirhabaxa, izinto ezirhabaxa, kunye nokusika i-semiconductor, akukho mntu wayelindele ukuba ivuselelwe kwakhona kwishishini le-ceramics. Sekunjalo, iye yavula iindlela ezintsha ezininzi kwishishini le-ceramics kwiminyaka yakutshanje.
1. Kutheni ndingazange ndiyicinge le nto ngaphambili? — “Ubuchule” bokuguqulwa kwe-micropowder
Iiceramics zisenokubonakala zilula, kodwa eneneni ziyinkimbinkimbi kakhulu. Imizimba yeceramic yendabuko idla ngokuqhekeka ngokungalinganiyo ngexesha lokomiswa nokutshiswa, nto leyo ekhokelela ekuqhekekeni. Iiglazes zidla ngokuqhekeka ngenxa yee-coefficients zokwandiswa kobushushu ezingahambelaniyo. Umahluko omkhulu obangelwa kukongeza i-silicon carbide micropowder eluhlaza kukuphuculwa kozinzo.
Ngenxa yobunzima bayo obuphezulu kunye nobukhulu beesuntswana ezincinci, ukufakwa kwayo emzimbeni kugcwalisa ngokufanelekileyo izithuba kwaye kudala isakhiwo esixineneyo. Ngamazwi engcali enamava, “Kufana nokuxova intlama imizuzu elishumi ngaphezulu—kuyenza ityebe ngakumbi.” Ngaphezu koko,i-silicon carbide eluhlaza Ukuqhuba kakuhle kobushushu be-micropowder kuqinisekisa ukusasazwa kobushushu obufanayo ngaphakathi kwi-oven, kunciphisa umngcipheko wokushisa kakhulu kwindawo ethile okanye ukutshisa ngaphantsi kobushushu. Kufana neebhanisi eziphekwa ngomphunga kwisitovu esiphekwa ngomthi, esasikade kunzima ukuzilawula. Ngoku, ii-steamers zanamhlanje zibonelela ngokhetho olungenangxaki, kodwa olusebenzayo.
2. Ingaphezulu nje kokuba “yiarhente yokuqinisa,” kodwa ikwaluphawu “lokunika amandla”.
Nangona kunjalo, ukujonga i-green silicon carbide micropowder nje "njenge-arhente yokuqinisa" bekuya kuba kukungathathelwa ngqalelo konke konke. Iifektri ze-ceramic zanamhlanje azisekho kuphela ekuveliseni izitya, izitya, kunye neembiza. Iimveliso eziphezulu ezifana ne-structural ceramics, i-electronic ceramics, kunye ne-ceramics ezingagugiyo ziya zithandwa kakhulu, kwaye i-green silicon carbide micropowder idlale indima "yengcali enqumla imida."
Umzekelo, ii-substrates ze-ceramic ze-elektroniki zifuna ukuhanjiswa kobushushu obuphezulu, ukufudumala okuphezulu, kunye nokwandiswa okuphantsi; nokuba ngumahluko omncinci unokuchaphazela ubomi bezinto ezisetyenzisiweyo. Ukongeza ubungakanani obufanelekileyo be-silicon carbide micropowder eluhlaza kuphucula kakhulu kungekuphela nje amandla oomatshini kodwa kunye nokuhanjiswa kobushushu. “Kufana nokubeka ijakethi enomoya opholileyo kwibhodi yesekethe,” watsho omnye unjineli.
Omnye umzekelo ziiseramikhi ezingagugiyo. Iilinings zeseramikhi zihlala zisetyenziswa kumatshini wemigodi nezixhobo zokuvelisa umbane oshushu. Ngaphambili, iiseramikhi ze-alumina zazigugiswa ngokukhawuleza kwaye zazifuna ukutshintshwa rhoqo. Ukongezwa kwe-silicon carbide micropowder eluhlaza kwandisa kakhulu ubulukhuni kunye nokumelana nokugugiswa kweeseramikhi, kwandisa ubomi bazo benkonzo ngaphezulu kwama-30%.
3. Umahluko phakathi "kokuba nomhlaba" kunye "nobuchwepheshe" yintwana nje ye-micropowder
Kusenokuba nzima ukucinga ukuba izinto zodongwe, ezazikade zithathwa njengeshishini lemveli "lodaka nomlilo," ngoku ziyamkela ngokuthula ubuchwepheshe obuphezulu. I-green silicon carbide micropowder yenye yezinto eziphambili eziguqule izinto zodongwe ukusuka "kwi-rustic" ukuya "kwi-high-tech."
Umzekelo, ezinye iinkampani okwangoku zizama ukuprinta nge-3D ukuvelisa iindawo zeseramikhi ezintsonkothileyo. Ezi nkqubo zihlala zingaphumeleli ngenxa yokuncipha okukhulu ngexesha lokuprinta. Ukongeza i-micropowder ye-silicon carbide eluhlaza kwi-slurry yeseramikhi kuphucula kakhulu ukubumbeka kunye nokuzinza kweendawo eziprintiweyo, okwenza ukuba neendawo zeseramikhi ezintle ziprintwe ngempumelelo ngexesha elinye.
Omnye umzekelo zizinto zesihluzo seseramikhi ezinobuhlobo nokusingqongileyo. Xa kusetyenzwa amanzi amdaka emizi-mveliso okanye igesi yokukhupha umoya, izihluzo zeseramikhi zemveli zidla ngokuvaleka kwaye azinamandla. Ukongezwa kwe-silicon carbide micropowder eluhlaza kubangela ukuba izinto zesihluzo zibe neembobo ezifanayo, iipropati zoomatshini eziphuculweyo, kunye nokumelana neekhemikhali okwandisiweyo, nto leyo eyenza ukuba zibe "zomelele kwaye zihlale ixesha elide" ngokwenene.
4. Nangona ngokuqinisekileyo kukho imingeni, indlela engaphambili iya phambili.
Ngelixai-micropowder eluhlaza ye-silicon carbideiyathembisa, ayisiyonto yokuphelisa iingxaki. Eyona ngxaki inkulu okwangoku ziindleko. I-micropowder ye-silicon carbide eluhlaza ecocekileyo kakhulu isabiza kakhulu, nto leyo eyenza ukuba ukusetyenziswa kwayo kube nzima kwiinkampani ezivelisa iiseramikhi eziphakathi nezisezantsi.
Ingxaki yesibini kukuguquguquka kwenkqubo. Iifomyula ezahlukeneyo zeseramikhi kunye neenkqubo zokudubula zifuna iimfuno ezithile zobukhulu beesuntswana kunye nomthamo weepowder ezincinci. Impumelelo ayinakufezekiswa nje "ngokuyiphosa ngetawuli." Ifuna uvavanyo olukhulu kunye neempazamo, kwaye ifuna notshintsho kwimigca yemveliso ekhoyo. "Kufuneka uwele umlambo ngokuva amatye, kodwa wakuba uyenzile kakuhle, indlela iba banzi kakhulu," utshilo umphathi wemveliso.
Nangona kunjalo, iinkampani ezininzi zizimisele ukutyala imali kuphando nophuhliso, kwaye iipowders ze-silicon carbide eziluhlaza eziveliswe apha ekhaya ezikumgangatho ophezulu ziye zaqaliswa. Amaxabiso aya efikeleleka ngakumbi, kwaye iteknoloji yokusebenzisa iyakhula.
5. Isiphelo: Umgubo Omncinci, Ikamva Elikhulu
Ukujonga emva, ukusetyenziswa kwe-green silicon carbide micropowder kwishishini le-ceramics ngumzekelo oqhelekileyo "wokutsha kwezinto eziqhuba ukuphuculwa kwemizi-mveliso." Endaweni yokuhlaziya ivili, ilungisa kwaye idibanise iinkqubo ezikhoyo, iphefumlela ubomi obutsha kubugcisa bendabuko.
Njengoko omnye umntu onamava kushishino watshoyo, “Iiceramics ziye zavela kwaye azitshintshanga kangangeminyaka engamawaka. Udongwe luhlala lufana, umlilo uhlala ufana, kodwa ukongeza into entsha kudala amathuba amatsha.”
Mhlawumbi uyilo lokwenyani lunje: akufuneki ukuba lube yinto eyoyikisa umhlaba, kufuneka nje ukuba lube lulungile. I-micropowder ye-silicon carbide eluhlaza yile nto kanye—ngokuzolileyo nangokungabonakaliyo iguqula uhlobo kunye nekamva le-ceramics.
Izinto zodongwe zexesha elizayo zinokuba zikhaphukhaphu, ziqine ngakumbi, kwaye zikrelekrele ngakumbi. Kwaye “amaqhawe angabonakaliyo” afana ne-silicon carbide micropowder eluhlaza asenokusizisela izinto ezimangalisayo ngakumbi.
