Impuphu ye-Alumina: impuphu yomlingo yokuthuthukisa ukusebenza komkhiqizo
Eshabhu lasefektri, uLao Li wayekhathazekile ngeqoqo lemikhiqizo phambi kwakhe: ngemuva kokudubula leli qoqo lemikhiqizoizisekelo ze-ceramic, kwakuhlale kunemifantu emincane ebusweni, futhi kungakhathaliseki ukuthi izinga lokushisa lesitofu lilungiswa kanjani, alizange libe nomthelela omkhulu. ULao Wang weza, walibuka isikhashana, wathatha isikhwama sempuphu emhlophe esandleni: “Zama ukwengeza okunye kwalokhu, Lao Li, mhlawumbe kuzosebenza.” ULao Wang unguchwepheshe wezobuchwepheshe efektri. Akakhulumi kakhulu, kodwa uhlala ethanda ukucabanga ngezinto ezintsha ezahlukahlukene. ULao Li wathatha isikhwama ngokunganaki, wabona ukuthi ilebula ithi “impuphu ye-alumina”.
Impuphu ye-Alumina? Leli gama lizwakala livamile, njengempuphu emhlophe evamile elabhorethri. Lingaba kanjani “impuphu yomlingo” engaxazulula izinkinga ezinzima? Kodwa uLao Wang walikhomba ngokuqiniseka wathi: “Ungalithathi kalula. Ngamandla alo, lingaxazulula ngempela izinkinga zakho eziningi.”
Kungani uLao Wang eyithanda kangaka le mpuphu emhlophe engabonakali? Isizathu empeleni silula - lapho singenakukwazi ukushintsha kalula umhlaba wonke wezinto ezibonakalayo, singase sizame ukwengeza "impuphu yomlingo" ukuze sishintshe ukusebenza kwezihluthulelo. Isibonelo, lapho izinto zobumba zendabuko zingaqinile ngokwanele futhi zithambekele ekuqhekekeni; izinsimbi azimelani ne-oxidation yokushisa okuphezulu; futhi amapulasitiki anomoya ophansi wokushisa, impuphu ye-alumina ivela ngokuthula bese iba "itshe lokuhlola" lokuxazulula lezi zinkinga ezibalulekile.
ULao Wang wake wabhekana nezinkinga ezifanayo. Ngalowo nyaka, wayenesibopho sesakhi esikhethekile sobumba esasidinga ukuba siqine, siqine, futhi simelane namazinga okushisa aphezulu.Izinto zobumba ezivamileziyasha, futhi amandla anele, kodwa zizoqhekeka kalula lapho zithintwa, njengengilazi ebuthakathaka. Wahola ithimba lakhe ukuba likhuthazelele izinsuku eziningi nobusuku elabhorethri, elungisa ngokuphindaphindiwe ifomula futhi eshisa ihhavini ngehhavini, kodwa umphumela waba ukuthi amandla ayengekho ezingeni elijwayelekile noma ubuthakathaka babuphezulu kakhulu, buhlala bulwa nobuthakathaka.
“Lezo zinsuku zazishisa kakhulu ubuchopho, futhi ngalahlekelwa izinwele eziningi,” kukhumbula uLao Wang kamuva. Ekugcineni, bazama ukwengeza ingxenye ethile yempuphu ye-alumina ehlanzekile kakhulu eyayicutshungulwe ngokunembile ezintweni zokusetshenziswa ze-ceramic. Lapho isithando somlilo sivulwa futhi, kwenzeka isimangaliso: izingxenye ze-ceramic ezisanda kushisa zenza umsindo ojulile nomnandi lapho zingqongqozwa. Lapho zizama ukusiphula ngamandla, zamelana namandla ngokuzikhandla futhi zazingasaphuki kalula - izinhlayiya ze-alumina zahlakazeka ngokulinganayo ku-matrix, njengokungathi inethiwekhi eqinile engabonakali yayilukiwe ngaphakathi, engagcini nje ngokuthuthukisa ubulukhuni, kodwa futhi yamunca buthule amandla okushaya, yathuthukisa kakhulu ubuthakathaka.
Kunganiimpuphu ye-alumina"Umlingo" onjalo? ULao Wang wadweba kancane inhlayiya encane ephepheni: "Bheka, le nhlayiya encane ye-alumina inobulukhuni obukhulu kakhulu, obufana ne-sapphire yemvelo, kanye nokumelana nokuguguleka kwesigaba sokuqala." Wama kancane, "Okubaluleke kakhulu, imelana namazinga okushisa aphezulu, futhi izakhiwo zayo zamakhemikhali zizinzile njengeNtaba iTai. Ayishintshi uhlobo lwayo emlilweni oshisa kakhulu, futhi ayigobi ikhanda layo kalula kuma-acid aqinile nama-alkali. Ngaphezu kwalokho, futhi iyisiqhubi esihle sokushisa, futhi ukushisa kugijima ngokushesha kakhulu ngaphakathi kwayo."
Uma lezi zici ezibonakala zizimele sezifakwe ngokunembile kwezinye izinto, kufana nokuguqula amatshe abe yigolide. Isibonelo, ukuyifaka ezintweni zobumba kungathuthukisa amandla nokuqina kwezinto zobumba; ukuyifaka ezintweni ezihlanganisiwe ezisekelwe ensimbi kungathuthukisa kakhulu ukumelana kwazo nokuguguleka kanye nekhono lokubekezelela amazinga okushisa aphezulu; ngisho nokuyifaka ezweni lepulasitiki kungavumela amapulasitiki ukuthi akhiphe ukushisa ngokushesha.
Embonini ye-elekthronikhi,impuphu ye-aluminafuthi yenza "umlingo". Namuhla, iyiphi ifoni ephathekayo noma ikhompyutha ephathekayo esezingeni eliphezulu engakhathazeki ngokushisa kwangaphakathi ngesikhathi sokusebenza? Uma ukushisa okukhiqizwa yizingxenye ze-elekthronikhi ezinembile kungenakuqedwa ngokushesha, ukusebenza kuzohamba kancane, futhi i-chip izolimala kakhulu. Onjiniyela bagcwalisa ngobuhlakani i-alumina powder eqhuba ukushisa okuphezulu ibe yi-silicone ekhethekile eqhuba ukushisa noma ipulasitiki yobunjiniyela. Lezi zinto eziqukethe i-alumina powder zinamathiselwe ngokucophelela ezingxenyeni eziyinhloko zokukhiqizwa kokushisa, njenge-"highway conduction conduction" ethembekile, eqondisa ngokushesha nangokuphumelelayo ukushisa okukhuphukayo ku-chip egobolondweni lokushabalalisa ukushisa. Idatha yokuhlola ikhombisa ukuthi ngaphansi kwezimo ezifanayo, izinga lokushisa eliyinhloko lemikhiqizo esebenzisa izinto eziqhuba ukushisa eziqukethe i-alumina powder lingancishiswa kakhulu ngamadigri angaphezu kweshumi noma ngisho namashumi amaningi uma kuqhathaniswa nezinto ezivamile, okuqinisekisa ukuthi imishini isasebenza ngokuthula nangokuzinzile ngaphansi komphumela wokusebenza onamandla.
ULao Wang wayevame ukuthi: “Umlingo wangempela awukho ku-powder uqobo, kodwa endleleni esiqonda ngayo inkinga futhi sithole iphuzu eliyinhloko elingasebenzisa ukusebenza kwayo.” Ikhono le-alumina powder alidalwanga ngeze, kodwa livela ezicini zalo ezivelele, futhi lihlanganiswe ngokufanele nezinye izinto, ukuze likwazi ukusebenzisa amandla alo buthule ngesikhathi esibucayi futhi liguqule ukubola kube umlingo.
Ebusuku kakhulu, uLao Wang wayesafunda amafomula amasha ehhovisi, futhi ukukhanya kwakubonakalisa isimo sakhe esigxile. Kwakuthule ngaphandle kwefasitela, kuphelaimpuphu ye-alumina esandleni sakhe kwakukhona ukukhanya okumhlophe okungabonakali ngaphansi kokukhanya, njengezinkanyezi ezincane ezingenakubalwa. Le mpuphu ebonakala ijwayelekile inikezwe imisebenzi ehlukene ngobusuku obungenakubalwa obufanayo, ihlanganiswa buthule ezintweni ezahlukahlukene, isekela phansi okunzima nokungagugi, iqinisekisa ukusebenza kwesikhathi eside nokuzolile kwemishini kagesi enembile, futhi iqapha ukuthembeka kwezingxenye ezikhethekile ezindaweni ezibucayi. Ukubaluleka kwesayensi yezinto kulele endleleni yokusebenzisa amandla ezinto ezivamile futhi uzenze zibe yisisekelo esibalulekile sokudlula ezinkingeni kanye nokuthuthukisa ukusebenza kahle.
Ngesikhathi esizayo lapho ubhekene nobunzima ekusebenzeni kwezinto ezibonakalayo, zibuze: Ingabe unengxenye "yempuphu ye-alumina" elinde ngokuthula ukuthi ivuswe ukuze idale leso sikhathi esibalulekile somlingo? Cabanga ngakho, ingabe lokhu kuyiqiniso?
