Kwihlabathi elikhulu lokuvelisa ngokuchanekileyo kunye nophando lwesayensi oluphambili, lonke ulawulo oluchanekileyo phakathi kwento encinci lunokubangela utshintsho kwezobuchwepheshe. Iqonga lokuhamba elihambayo lomoya oxinzelelweyo, njengesixhobo esiphambili sokufezekisa intshukumo echanekileyo kakhulu, ukusebenza kwayo kumisela ngokuthe ngqo impumelelo okanye ukungaphumeleli kweziphumo. Isiseko segranite sisixhobo esiyimfihlo esisinika ukuchaneka okungaqhelekanga kunye nozinzo olugqwesileyo.
Isiseko esizinzileyo esenziwe ngendalo
I-Granite, emva kwezigidi zeminyaka yotshintsho lwejoloji, isakhiwo sangaphakathi sixinene kwaye siyafana, yi-quartz, i-feldspar kunye nezinye iiminerali ezidityaniswe ngokusondeleyo. Esi sakhiwo sikhethekileyo sinika uzinzo olungenakuthelekiswa nanto. Xa kujongwe ukuphazamiseka kwangaphandle, nokuba kukungcangcazela okunamandla okubangelwa kukusebenza kwezixhobo ezinkulu kwindawo yokusebenzela, okanye ukuguquguquka okukhulu kubushushu obungqongileyo, isiseko se-granite sinokujamelana nayo ngokuzolileyo. Iimpawu zayo ezintle zokuncitshiswa kokungcangcazela, njenge-shock absorber yobungcali, zinokunciphisa ubukhulu bokungcangcazela kweqonga lokuhamba elihambayo lomoya oxinzelelweyo ngaphezulu kwe-80%, zibonelela ngendawo yokusebenza ezolileyo nezinzileyo yeqonga ukuqinisekisa ukuba kwinkqubo yokucubungula okanye ukufumanisa ngokuchanekileyo, intshukumo igudile kwaye ayinamkhethe.
Inzuzo yozinzo lobushushu, isiseko sokuchaneka kokulawula
Utshintsho lobushushu yingxaki enkulu echaphazela ukuchaneka kwezixhobo ezichanekileyo, kodwa isiseko segranite esine-coefficient ephantsi kakhulu yokwandiswa kobushushu, sisombulula lula le ngxaki. I-coefficient yayo yokwandiswa kobushushu ngokubanzi yi-5-7 × 10⁻⁶/℃, kwaye utshintsho lobungakanani luncinci xa ubushushu butshintshatshintsha. Kwinkqubo ye-photolithography yokwenziwa kweetshiphusi ze-semiconductor, ukuchaneka kokubekwa kufuneka kube kwinqanaba le-danamil, kwaye utshintsho oluncinci kubushushu lunokukhokelela ekuphambukeni kwipateni yetshiphusi. Iqonga lokuhamba elihambayo lomoya oxinzelelweyo oqinileyo oxhotyiswe ngesiseko segranite linokuhlala ligcina ukuchaneka kokubekwa okuzinzileyo phantsi kobushushu obuntsonkothileyo, lincede ukuveliswa kweetshiphusi ukufezekisa ukuhlanganiswa okuphezulu kunye nesivuno, kwaye lifake amandla amakhulu kuphuhliso lweshishini le-semiconductor.
Ubulukhuni obuphezulu, ukumelana nokuguguleka, isiqinisekiso sokuqina
Kwixesha elide leqonga elihambayo lomoya oxinzelelweyo oqinileyo, nangona kukho inkxaso yokuhamba komoya phakathi kweqonga kunye nesiseko, ukungqubana rhoqo akuphepheki. Ubunzima begranite buphezulu, ubunzima beMohs bunokufikelela kwi-6-7, kunye nokumelana okuhle kokuguguleka. Kwilabhoratri yesayensi yezinto, iqonga elihambayo lomoya oxinzelelweyo oqinileyo osetyenziswa rhoqo, isiseko salo segranite sinokumelana ngempumelelo nokulahleka kokungqubana kwexesha elide, xa kuthelekiswa nesiseko esiqhelekileyo, sinokwandisa umjikelo wokugcinwa kweqonga ngaphezulu kwe-50%, kunciphisa kakhulu iindleko zokugcinwa kwezixhobo, ukuqinisekisa uphuhliso olusebenzayo noluqhubekayo lomsebenzi wophando lwesayensi.
Ukukhetha iqonga elihambayo lomoya elichanekileyo elinomoya omanzi oxhotyiswe ngesiseko segranite kukukhetha ukuchaneka okugqibeleleyo, uzinzo oluhle kakhulu kunye nokuqina kwexesha elide. Kwimveliso ye-semiconductor, imveliso yezixhobo ze-optical, i-aerospace, uphando lwesayensi kunye novavanyo kunye nezinye iimfuno zokuchaneka kweli candelo, idlala indima ebalulekileyo engenakutshintshwa, ikhokelela kushishino ukuba ludlule kumda wokuchaneka, ukuya kwinqanaba lophuhliso elinobungcali ngakumbi, ukubonelela ngenkxaso yobugcisa eqinileyo nethembekileyo kwimpumelelo yakho yomsebenzi.
