Ezinkambini ezisezingeni eliphezulu njengokwenziwa kwe-semiconductor chip kanye nokuhlola okunembayo okunembayo, izinzwa zokunemba okuphezulu zingamadivayisi ayinhloko okuthola idatha ebalulekile. Kodwa-ke, izindawo eziyinkimbinkimbi zikazibuthe kanye nezimo zomzimba ezingazinzile zivame ukuholela kudatha yokulinganisa engalungile. Isisekelo se-granite, esinezinto ezingezona uzibuthe, ezivikelwe kanye nokuzinza okuhle ngokomzimba, sakha indawo ethembekile yokulinganisa yenzwa.
Imvelo engeyona enozibuthe inqamula umthombo wokuphazamiseka
Izinzwa zokunemba okuphezulu njengezinzwa zokususwa kwe-inductive nezikali zikazibuthe zizwela kakhulu ezinguqukweni zenkundla kazibuthe. I-magnetism engokwemvelo yezisekelo zensimbi zomdabu (ezifana nensimbi ne-aluminium alloy) ingakha inkambu kazibuthe ephazamisayo ezungeze inzwa. Uma inzwa isebenza, inkambu kazibuthe yokuphazamiseka kwangaphandle isebenzisana nenkundla kazibuthe yangaphakathi, engabangela kalula ukuchezuka kwedatha yokulinganisa.
I-Granite, njengedwala lemvelo elivuthayo, lakhiwe ngamaminerali afana ne-quartz, i-feldspar ne-mica. Ukwakheka kwayo kwangaphakathi kunquma ukuthi ayinawo nhlobo uzibuthe. Faka inzwa kusisekelo segranite ukuze ukhiphe ukuphazamiseka kazibuthe kwesisekelo kusuka empandeni. Kumathuluzi anembayo njengama-electron microscopes kanye ne-nuclear magnetic resonance, isisekelo se-granite siqinisekisa ukuthi inzwa ithwebula ngokunembile izinguquko ezicashile zento eqondiwe, igwema amaphutha okulinganisa abangelwa ukuphazamiseka kazibuthe.
Izici zesakhiwo zixhunywe ngesivikelo se-electromagnetic
Nakuba i-granite ingenalo ikhono lokuvikela i-conductive njengensimbi, isakhiwo sayo somzimba esiyingqayizivele singaphinda senze buthaka ukuphazamiseka kwe-electromagnetic. I-Granite iqinile ngokwakheka futhi iminyene ngesakhiwo. Ukuhlelwa okuhlanganisiwe kwamakristalu amaminerali kwakha umgoqo womzimba. Lapho amagagasi kagesi angaphandle asakazekela esisekelweni, ingxenye yamandla imuncwa ikristalu futhi iguqulelwe amandla okushisa, futhi ingxenye iboniswa futhi isakazeke endaweni yekristalu, ngaleyo ndlela kunciphisa ukuqina kwamagagasi kagesi afinyelela kunzwa.
Ekusetshenzisweni okungokoqobo, izisekelo ze-granite zivame ukuhlanganiswa namanetha okuvikela ensimbi ukuze zakhe izakhiwo eziyinhlanganisela. Imeshi yensimbi ivimba amagagasi kagesi anemvamisa ephezulu, futhi igwadule lenza buthaka kakhulu ukuphazamiseka okusalayo ngenkathi inikeza ukusekelwa okuzinzile. Ezingqungqutheleni zezimboni ezigcwele iziguquli zefrikhwensi namamotho, le nhlanganisela yenza izinzwa zisebenze ngokuzinzile ngisho nasendaweni eqinile ye-electromagnetic.
Zinzisa izakhiwo zomzimba futhi uthuthukise ukwethembeka kwesilinganiso
I-coefficient yokunwetshwa okushisayo kwe-granite iphansi kakhulu (kuphela (4-8) × 10⁻⁶/℃), futhi usayizi wayo ushintsha kancane kakhulu lapho izinga lokushisa lishintshashintsha, liqinisekisa ukuzinza kwendawo yokufaka inzwa. Ukusebenza kwayo okuhle kakhulu kokudambisa kungamunca ngokushesha ukudlidliza kwemvelo futhi kunciphise umthelela wokuphazamiseka kwemishini ezilinganisweni. Esilinganisweni se-optical esinembayo, isisekelo se-granite singavimbela indlela yokubona ebangelwa ukuwohloka kwe-thermal nokudlidliza, iqinisekise ukunemba nokuphindaphindwa kwedatha yokulinganisa.
Esimeni sokutholwa kwe-wafer ye-semiconductor, ngemuva kokuthi ibhizinisi elithile lamukele isisekelo se-granite, iphutha lokulinganisa lehla lisuka ku-±5μm laya phakathi kuka-±1μm. Ngendlela kanye nokuhlolwa kokubekezelela isikhundla kwezingxenye ze-aerospace, isistimu yokulinganisa esebenzisa isisekelo segwadle ithuthukise ukuphindaphinda kwedatha ngaphezu kuka-30%. Lezi zimo zibonisa ngokugcwele ukuthi isisekelo se-granite sithuthukisa kakhulu ukuthembeka kokulinganisa kwezinzwa ezinemba okuphezulu ngokususa ukuphazamiseka kukazibuthe kagesi kanye nokusimamisa indawo ezungezile, okuyenza ibe yingxenye esemqoka ebaluleke kakhulu emkhakheni wesimanje wokulinganisa ukunemba.
