Upfu hweAlumina: upfu hwemashiripiti hwekuvandudza mashandiro echigadzirwa
Mufekitori, Lao Li ainetseka nezveboka rezvigadzirwa pamberi pake: mushure mekudzinga boka iri rezvigadzirwazvigadziko zvedongo, paigara paine tumaburi tudiki pamusoro, uye zvisinei nekuti tembiricha yechoto yaigadziriswa sei, haina zvainobatsira zvakanyanya. Lao Wang akauya, akaitarisa kwechinguva, ndokutora bhegi reupfu chena raivapo: “Edza kuwedzera zvimwe zveizvi, Lao Li, pamwe zvichashanda.” Lao Wang inyanzvi yehunyanzvi mufekitori. Haatauri zvakawanda, asi anogara achida kufunga nezvezvinhu zvitsva zvakasiyana-siyana. Lao Li akatora bhegi racho nemoyo wese, ndokuona kuti chikwangwani chakanyorwa kuti “upfu hwealumina”.
Upfu hweAluminaZita iri rinonzwika serisingawanzoitiki, kungofanana neupfu huchena hunowanikwa murabhoritari. Ringava sei "upfu hwemashiripiti" hunogona kugadzirisa matambudziko akaoma? Asi Lao Wang akarinongedzera nechivimbo ndokuti: "Usahurerutse. Nekugona kwaro, rinogona kugadzirisa matambudziko ako mazhinji."
Sei Lao Wang achiyemura upfu huchena husingaonekwe kudaro? Chikonzero chacho chiri nyore - kana tisingakwanise kuchinja zvinhu zvese zviri munyika, tingatofanira kuedza kuwedzera "upfu hwemashiripiti" kuti tichinje mashandiro azvo. Semuenzaniso, kana zviumbwa zvechinyakare zvisina kusimba zvakakwana uye zvichitsemuka; simbi hadzina kusimba kuoxidation yekupisa kwakanyanya; uye mapurasitiki asina kufambiswa zvakanaka kwekupisa, upfu hwealumina hunoonekwa chinyararire uye hunova "dombo rekuongorora" kugadzirisa matambudziko aya makuru.
Lao Wang akambosangana nematambudziko akafanana. Gore iroro, ndiye akagadzira chinhu chakakosha checeramic chaida kuti chive chakaoma, chakasimba, uye chisingapindi kupisa kwakanyanya.Zvinhu zvechinyakare zveceramicZvinopiswa, uye simba razvo rakakwana, asi zvinotsemuka zvisina kusimba kana zvikagunzwa, segirazi rinoputsika. Akatungamira timu yake kuti itsungirire mazuva nehusiku zvisingaverengeki murabhoritari, achigadzirisa kakawanda fomura uye achipisa chitofu chimwe nechimwe, asi mhedzisiro yacho yaive yekuti simba racho rakanga risiri renguva yakatarwa kana kuti kuputsika kwacho kwakanga kwakanyanya, nguva dzose zvichitambura nekuputsika.
"Mazuva iwayo aipisa pfungwa, uye ndakarasikirwa nebvudzi rakawanda," Lao Wang akayeuka kudaro gare gare. Pakupedzisira, vakaedza kuwedzera chikamu chaicho cheupfu hwealumina hwakachena hwakanga hwagadzirwa nemazvo muzvinhu zvakagadzirwa neceramic. Pakavhurwa chitofu zvakare, chishamiso chakaitika: zvikamu zveceramic zvitsva zvakatanga kupiswa zvakaita ruzha rwakadzama uye runonakidza pazvakagogodzwa. Pakuedza kuipwanya nesimba, yakaramba simba racho nesimba uye yakanga isisatyoke nyore nyore - zvidimbu zvealumina zvakapararira zvakaenzana mu matrix, sekunge network yakasimba isingaoneki yakanga yakarukwa mukati, iyo isina kungovandudza kuomarara chete, asiwo yakanyudza chinyararire simba reinjini, zvichivandudza zvikuru kuputsika.
Sei uchidaroupfu hwealuminavane "mashiripiti" akadaro? Lao Wang akadhirowa kachidimbu kadiki papepa: "Tarira, kachidimbu aka kadiki kealumina kane kuomarara kwakanyanya, kwakafanana nesafire yechisikigo, uye kusakara kwemhando yepamusoro." Akambomira, "Chinonyanya kukosha ndechekuti kanodzivirira kupisa kwakanyanya, uye hunhu hwako hwemakemikari hwakagadzikana seMount Tai. Hakachinje hunhu hwako mumoto unodziya zvakanyanya, uye hakakotamisi musoro wako muacids nealkalis zvine simba. Pamusoro pezvo, zvakare inodzora kupisa zvakanaka, uye kupisa kunomhanya nekukurumidza mukati mayo."
Kana hunhu uhwu hunoita sehwakazvimirira hwanyatsoiswa mune zvimwe zvinhu, zvinoita sekushandura matombo kuita goridhe. Semuenzaniso, kuiisa muzviumbwa zvesimbi kunogona kuwedzera simba uye kusimba kwezviumbwa zvesimbi; kuiisa muzviumbwa zvesimbi zvinogona kuwedzera zvakanyanya kusakara kwadzo uye kugona kwadzo kutsungirira tembiricha dzakakwirira; kunyangwe kuiisa munyika yepurasitiki kunogona kubvumira mapurasitiki kuti akurumidze kuendesa kupisa.
Muindasitiri yezvemagetsi,upfu hwealuminainoitawo "mashiripiti". Mazuva ano, ndeipi nharembozha yepamusoro kana laptop isinganetseke nezvekupisa kwemukati panguva yekushanda? Kana kupisa kunogadzirwa nezvinhu zvemagetsi zvakarurama kusingakwanise kunyangarika nekukurumidza, mashandiro acho anononoka, uye chip ichakuvara zvakanyanya. Mainjiniya anozadza nehungwaru alumina powder ine thermal conductivity yakakura kuita special thermal conductive silicone kana engineering plastics. Zvinhu izvi zvine alumina powder zvinonamirwa zvakanyatsonaka kune zvikamu zvepakati zvekupisa, se "thermal conduction highway", iyo inotungamira nekukurumidza uye zvinobudirira kupisa kuri pamusoro pechip kuenda kugoko rekuparadza kupisa. Data rekuyedza rinoratidza kuti pasi pemamiriro akafanana, tembiricha yepakati yezvigadzirwa zvinoshandisa thermal conductive zvinhu zvine alumina powder inogona kuderedzwa zvakanyanya neanopfuura gumi kana kunyange makumi maviri emadhigirii zvichienzaniswa nezvinhu zvemazuva ano, zvichiita kuti michina irambe ichimhanya yakanyarara uye yakadzikama pasi pesimba rekushanda.
Lao Wang aiwanzoti: “'Mashiripiti' chaiwo haasi muupfu pachahwo, asi pakuti tinonzwisisa sei dambudziko uye tinowana pfungwa huru inogona kushandisa mashandiro aro.” Kugona kweupfu hwealumina hakuna kugadzirwa pasina, asi kunobva muhunhu hwahwo hwakanaka, uye kwakabatanidzwa zvakakodzera mune zvimwe zvinhu, kuitira kuti igone kushandisa simba rayo chinyararire panguva yakakosha uye kushandura kuora kuita mashiripiti.
Husiku chaihwo, Lao Wang akanga achiri kudzidza mafomula matsva ebasa muhofisi, uye chiedza chairatidza chimiro chake chakatarisa. Kwakanga kwakanyarara kunze kwehwindo, cheteupfu hwealumina Muruoko rwake makanga muchipenya kuchena kusina kujeka pasi pechiedza, senyeredzi diki dzisingaverengeki. Upfu uhwu hunoratidzika kunge hwakajairika hwakapihwa mabasa akasiyana-siyana muhusiku hwakafanana husingaverengeki, huchibatanidzwa chinyararire muzvinhu zvakasiyana-siyana, huchitsigira pasi rakasimba uye risingaparare, huchivimbisa kushanda kwenguva refu uye kwakadzikama kwemidziyo yemagetsi chaiyo, uye kuchengetedza kuvimbika kwezvikamu zvakakosha munzvimbo dzakaoma. Kukosha kwesainzi yezvinhu kuri mukuti ungashandisa sei kugona kwezvinhu zvakajairika uye kuzviita mhedzisiro huru yekupfuura nematambudziko nekuvandudza kushanda zvakanaka.
Nguva inotevera paunosangana nedambudziko guru mukushanda kwezvinhu, zvibvunze kuti: Une chidimbu che "alumina powder" chakamirira chinyararire kumutswa kuti chigadzire nguva iyoyo inokosha yemashiripiti here? Funga nezvazvo, ichi ndicho chokwadi here?
