Umgubo we-Alumina: umgubo womlingo wokuphucula ukusebenza kwemveliso
Kwindawo yokusebenzela yefektri, uLao Li wayexhalabile ngeqela leemveliso phambi kwakhe: emva kokudubula eli qela leii-substrates zeseramikhi, bekukho imingxunya emincinci phezu komhlaba, kwaye nokuba ubushushu be-oven buhlengahlengiswa njani, abuzange bube nampembelelo ingako. ULao Wang weza, wayijonga okomzuzwana, waza wathabatha ingxowa yomgubo omhlophe esandleni: “Zama ukongeza oku, Lao Li, mhlawumbi kuya kusebenza.” ULao Wang yingcali kwezobugcisa kumzi-mveliso. Akathethi kakhulu, kodwa uhlala ethanda ukucinga ngezinto ezintsha ezahlukeneyo. ULao Li wathabatha ingxowa ngokungakhathali, waza wabona ukuba ileyibhile ithi “umgubo we-alumina”.
Umgubo we-AluminaEli gama livakala liqhelekile, njengomgubo omhlophe oqhelekileyo kwilebhu. Lingaba njani “ngumgubo womlingo” onokusombulula iingxaki ezinzima? Kodwa uLao Wang walikhomba ngokuzithemba wathi: “Ungalithathi lula. Ngobuchule balo, linokuzisombulula ngokwenene iintloko zakho ezininzi.”
Kutheni uLao Wang eyithanda kangaka le powder emhlophe engabonakaliyo? Isizathu silula ngokwenene - xa singenakukwazi ukutshintsha ngokulula lonke ihlabathi lezinto ezibonakalayo, singazama ukongeza "ipowder yomlingo" ukutshintsha ukusebenza kwesitshixo. Umzekelo, xa iiceramics zemveli zingomelelanga ngokwaneleyo kwaye ziqhele ukuqhekeka; iintsimbi azixhathisi kwi-oxidation yobushushu obuphezulu; kwaye iiplastiki zinomoya ophantsi wokuhambisa ubushushu, i-alumina powder ivela kancinci kwaye ibe "lilitye lokuchukumisa" ukusombulula ezi ngxaki ziphambili.
ULao Wang wakha wadibana neengxaki ezifanayo. Ngaloo nyaka, wayenoxanduva lwecandelo elikhethekileyo le-ceramic elalifuna ukuba liqine, liqine, kwaye likwazi ukumelana namaqondo obushushu aphezulu.Izixhobo zeseramikhi eziqhelekileyoziyadutyulwa, kwaye amandla anele, kodwa ziya kuqhekeka kancinci xa zichukunyiswa, njengeqhekeza leglasi ebuthathaka. Wakhokela iqela lakhe ukuba linyamezele iintsuku ezininzi nobusuku elabhoratri, elungisa ngokuphindaphindiweyo ifomula kwaye etshisa i-oven emva kwenye, kodwa isiphumo saba kukuba amandla ayengekho semgangathweni okanye ubuthathaka babuphezulu kakhulu, besoloko besokola ngenxa yobuthathaka.
“Ezo ntsuku zazitshisa ingqondo kakhulu, kwaye ndalahlekelwa ziinwele ezininzi,” wakhumbula uLao Wang kamva. Ekugqibeleni, bazama ukongeza umlinganiselo othile wepowder ye-alumina ecocekileyo kakhulu eyayicutshungulwe ngokuchanekileyo kwizinto eziluhlaza ze-ceramic. Xa i-oven yavulwa kwakhona, kwenzeka ummangaliso: iindawo ze-ceramic ezisandul’ ukutsha zenza isandi esinzulu nesimnandi xa zibethelwa. Xa bezama ukuyiqhekeza ngamandla, yamelana namandla ngamandla kwaye ayisaphuki lula - amasuntswana e-alumina asasazeke ngokulinganayo kwi-matrix, ngokungathi kukho inethiwekhi eqinileyo engabonakaliyo eyayilukiwe ngaphakathi, engaphuculanga kuphela ubunzima, kodwa ikwafunxa amandla empembelelo buthule, iphucula kakhulu ubulukhuni.
Kutheni le ntoumgubo we-alumina"Umlingo" onjalo? ULao Wang wazoba isuntswana elincinci ephepheni ngokungakhathali: "Khangela, le suntswana incinci ye-alumina inobunzima obuphezulu kakhulu, obufana nesafire yendalo, kunye nokumelana nokuguguleka kodidi lokuqala." Wama kancinci, "Okubaluleke ngakumbi, iyamelana namaqondo obushushu aphezulu, kwaye iipropati zayo zeekhemikhali zizinzile njengeMount Tai. Ayitshintshi indalo yayo kumlilo obushushu obuphezulu, kwaye ayigobi intloko yayo kwiiasidi ezinamandla kunye neealkalis. Ukongeza, ikwangumqhubi wobushushu olungileyo, kwaye ubushushu buhamba ngokukhawuleza ngaphakathi kuyo."
Xa ezi mpawu zibonakala zizimeleyo zingeniswe ngokuchanekileyo kwezinye izinto, kufana nokuguqula amatye abe yigolide. Umzekelo, ukuyongeza kwi-ceramics kunokuphucula amandla kunye nokuqina kwe-ceramics; ukuyifaka kwi-composite esekwe kwisinyithi kunokuphucula kakhulu ukumelana kwayo nokuguguleka kunye nokukwazi kwayo ukumelana namaqondo obushushu aphezulu; kwanokuyongeza kwihlabathi leplastiki kunokuvumela iiplastiki ukuba zikhuphe ubushushu ngokukhawuleza.
Kwishishini le-elektroniki,umgubo we-aluminaikwasebenza "njengomlingo". Kule mihla, yeyiphi ikhompyutha ephathekayo okanye ilaptop ekumgangatho ophezulu engakhathazeki ngokufudumeza kwangaphakathi ngexesha lokusebenza? Ukuba ubushushu obuveliswa zizinto ze-elektroniki ezichanekileyo abunakusasazeka ngokukhawuleza, umsebenzi uya kucotha kakhulu, kwaye itshiphu iya konakala kakhulu. Iinjineli ngobuchule zizalisa umgubo we-alumina oqhuba ubushushu obuphezulu kwi-silicone ekhethekileyo yokuqhuba ubushushu okanye iiplastiki zobunjineli. Ezi zinto ziqulethe umgubo we-alumina zincamathiselwe ngononophelo kwiindawo eziphambili zokuvelisa ubushushu, njenge-"highway conduction conduction", ekhokela ngokukhawuleza nangokufanelekileyo ubushushu obukhulayo kwitshiphu ukuya kwigobolondo yokusasaza ubushushu. Idatha yovavanyo ibonisa ukuba phantsi kweemeko ezifanayo, ubushushu obuphambili beemveliso ezisebenzisa izixhobo zokuqhuba ubushushu eziqulethe umgubo we-alumina bunokunciphisa kakhulu ngaphezulu kweshumi okanye amashumi amabini eedigri xa kuthelekiswa nezixhobo eziqhelekileyo, ukuqinisekisa ukuba izixhobo zisenokusebenza ngokuzolileyo nangokuzinzileyo phantsi kwemveliso enamandla yokusebenza.
ULao Wang wayedla ngokuthi: “Umlingo wokwenene awukho kwimpuphu ngokwayo, kodwa kwindlela esiyiqonda ngayo ingxaki size sifumane ingongoma ephambili enokusebenzisa ukusebenza kwayo.” Amandla empuphu ye-alumina awadalwanga ngaphandle kwento, kodwa avela kwiimpawu zayo ezibalaseleyo, kwaye adityaniswe ngokufanelekileyo kwezinye izinto, ukuze ikwazi ukusebenzisa amandla ayo ngokuzolileyo ngexesha elibalulekileyo kwaye iguqule ukubola kube ngumlingo.
Ebusuku kakhulu, uLao Wang wayesafunda iifomyula ezintsha zezinto eofisini, kwaye ukukhanya kwakubonakalisa umzimba wakhe ogxile. Kwakuthule ngaphandle kwefestile, kuphelaumgubo we-alumina esandleni sakhe kwakukho ukukhanya okumhlophe okukhanyayo phantsi kokukhanya, njengeenkwenkwezi ezincinci ezingenakubalwa. Le mpuphu ibonakala iqhelekile inikwe imisebenzi eyahlukeneyo ngobusuku obungenakubalwa obufanayo, idityaniswe buthule kwizinto ezahlukeneyo, ixhasa umgangatho oqinileyo nongagugiyo, iqinisekisa ukusebenza kwexesha elide nokuzolileyo kwezixhobo ze-elektroniki ezichanekileyo, kwaye ikhusela ukuthembeka kwezinto ezikhethekileyo kwiindawo ezixineneyo. Ixabiso lesayensi yezinto likwindlela yokusebenzisa amandla ezinto eziqhelekileyo kwaye uzenze zibe sisiseko esibalulekileyo sokugqobhoza imiqobo kunye nokuphucula ukusebenza kakuhle.
Ngexesha elizayo xa ujongene nomqobo ekusebenzeni kwezinto ezibonakalayo, zibuze: Ngaba unayo iqhekeza "lomgubo we-alumina" elilinde ngokuzolileyo ukuba livuswe ukuze lenze elo xesha libalulekileyo lomlingo? Cinga ngayo, ngaba le yinyaniso?
