I-coefficient yokwandisa ethe tye yegranite idla ngokuba malunga ne-5.5-7.5x10 - ⁶/℃. Nangona kunjalo, kwiintlobo ezahlukeneyo zegranite, i-coefficient yayo yokwandisa inokwahluka kancinci.
I-granite inozinzo oluhle lobushushu, ikakhulu ibonakala kwezi zinto zilandelayo:
Ukuguquguquka okuncinci kobushushu: ngenxa yokwanda okuphantsi komlinganiselo, ukuguquguquka kobushushu begranite kuncinci xa ubushushu butshintsha. Oku kuvumela izinto zegranite ukuba zigcine ubungakanani obuzinzileyo kunye nemilo kwiindawo ezahlukeneyo zobushushu, nto leyo enceda ekuqinisekiseni ukuchaneka kwezixhobo ezichanekileyo. Umzekelo, kwizixhobo zokulinganisa ezichanekileyo, ukusetyenziswa kwegranite njengesiseko okanye ibhentshi yokusebenzela, nokuba ubushushu obuphakathi bunokuguquguquka okuthile, ukuguquguquka kobushushu kunokulawulwa kuluhlu oluncinci, ukuqinisekisa ukuchaneka kweziphumo zokulinganisa.
Ukumelana kakuhle nokutshayiswa kobushushu: I-Granite inokumelana notshintsho oluthile lobushushu olukhawulezileyo ngaphandle kokuqhekeka okanye umonakalo obonakalayo. Oku kungenxa yokuba inomoya ofanelekileyo wobushushu kunye namandla obushushu, anokudlulisa ubushushu ngokukhawuleza nangokulinganayo xa ubushushu butshintsha, nto leyo enciphisa uxinzelelo lobushushu lwangaphakathi. Umzekelo, kwezinye iindawo zemveliso yemizi-mveliso, xa izixhobo ziqala okanye ziyeka ukusebenza ngequbuliso, ubushushu buya kutshintsha ngokukhawuleza, kwaye izinto ze-granite zinokuziqhelanisa ngcono nolu tshatyalaliso lobushushu kwaye zigcine uzinzo lokusebenza kwazo.
Uzinzo oluhle lwexesha elide: Emva kwexesha elide lokwaluphala kwendalo kunye nesenzo sejoloji, uxinzelelo lwangaphakathi lwegranite luye lwakhululwa ngokusisiseko, kwaye isakhiwo sizinzile. Kwinkqubo yokusetyenziswa kwexesha elide, nokuba emva kotshintsho oluninzi lomjikelo wobushushu, isakhiwo salo sangaphakathi asilula ukusitshintsha, sinokuqhubeka nokugcina uzinzo oluhle lobushushu, sibonelela ngenkxaso ethembekileyo kwizixhobo ezichanekileyo.
Xa kuthelekiswa nezinye izinto eziqhelekileyo, uzinzo lobushushu lwegranite lukwinqanaba eliphezulu, oku kulandelayo kukuthelekisa phakathi kwezinto zegranite nezesinyithi, izinto zeseramikhi, izinto ezidityanisiweyo ngokubhekiselele kuzinzo lobushushu:
Xa kuthelekiswa nezinto zesinyithi:
I-coefficient yokwandiswa kobushushu bezinto zesinyithi ngokubanzi inkulu kakhulu. Umzekelo, i-coefficient yokwandiswa komgca wentsimbi eqhelekileyo yekhabhoni imalunga ne-10-12x10 - ⁶/℃, kwaye i-coefficient yokwandiswa komgca we-aluminium alloy imalunga ne-20-25x10 - ⁶/℃, ephezulu kakhulu kune-granite. Oku kuthetha ukuba xa ubushushu butshintsha, ubungakanani bezinto zesinyithi butshintsha kakhulu, kwaye kulula ukuvelisa uxinzelelo olukhulu lwangaphakathi ngenxa yokwanda kobushushu kunye nokuxinana okubandayo, ngaloo ndlela kuchaphazela ukuchaneka kunye nokuzinza kwayo. Ubungakanani begranite buyatshintsha kancinci xa ubushushu butshintsha, nto leyo enokugcina ngcono imo yokuqala kunye nokuchaneka. Ukuqhuba kobushushu bezinto zesinyithi kudla ngokuba phezulu, kwaye kwinkqubo yokufudumeza okanye ukupholisa ngokukhawuleza, ubushushu buya kuqhutywa ngokukhawuleza, nto leyo ebangela umahluko omkhulu wobushushu phakathi kwangaphakathi kunye nomphezulu wezinto, nto leyo ebangela uxinzelelo lobushushu. Ngokwahlukileyo koko, ukuqhuba kobushushu begranite kuphantsi, kwaye ukuqhuba kobushushu kuhamba kancinci, nto leyo enokunciphisa ukuveliswa koxinzelelo lobushushu ukuya kwinqanaba elithile kwaye ibonise uzinzo olungcono lobushushu.
Xa kuthelekiswa nezinto zeseramikhi:
I-coefficient yokwandiswa kobushushu kwezinye izinto zeseramikhi ezisebenza kakuhle inokuba phantsi kakhulu, njenge-silicon nitride ceramics, apho i-coefficient yokwandiswa kwayo imalunga ne-2.5-3.5x10 - ⁶/℃, ephantsi kune-granite, kwaye ineenzuzo ezithile ekuzinzeni kobushushu. Nangona kunjalo, izixhobo zeseramikhi zihlala zibuthathaka, ukumelana nokushukuma kobushushu kuphantsi kakhulu, kwaye ukuqhekeka okanye nokuba kukuqhekeka kulula ukwenzeka xa ubushushu butshintsha ngokukhawuleza. Nangona i-coefficient yokwandiswa kobushushu ye-granite iphezulu kancinci kunezinye iiseramikhi ezikhethekileyo, inokuqina okuhle kunye nokumelana nokushukuma kobushushu, inokumelana nenqanaba elithile lotshintsho lobushushu, kwizicelo ezisebenzayo, kwiindawo ezininzi zokutshintsha kobushushu obungengobugqithisileyo, ukuzinza kobushushu be-granite kunokuhlangabezana neemfuno, kwaye ukusebenza kwayo okubanzi kulungelelene ngakumbi, ixabiso liphantsi kakhulu.
Xa kuthelekiswa nezinto ezidityanisiweyo:
Ezinye izinto ezidityanisiweyo eziphambili zinokufikelela kwi-coefficient ephantsi yokwandiswa kobushushu kunye nokuzinza okuhle kobushushu ngoyilo olufanelekileyo lokudibanisa ifayibha kunye ne-matrix. Umzekelo, i-coefficient yokwandiswa kobushushu kwezinto ezidityanisiweyo ze-carbon fiber inokulungiswa ngokwesikhokelo kunye nomxholo wefayibha, kwaye inokufikelela kumaxabiso aphantsi kakhulu kwiindlela ezithile. Nangona kunjalo, inkqubo yokulungiselela izinto ezidityanisiweyo iyinkimbinkimbi kwaye ixabiso liphezulu. Njengezinto zendalo, i-granite ayidingi nkqubo yokulungiselela enzima, kwaye ixabiso liphantsi kakhulu. Nangona isenokungabi ntle njengezinye izinto ezidityanisiweyo eziphezulu kwezinye izalathisi zozinzo lobushushu, ineenzuzo ngokubhekiselele ekusebenzeni kweendleko, ngoko ke isetyenziswa kakhulu kwizicelo ezininzi zesiqhelo ezineemfuno ezithile zozinzo lobushushu. Kumashishini asetyenziswa izinto ze-granite, ukuzinza kobushushu yeyona nto iphambili? Nika idatha ethile yovavanyo okanye iimeko zozinzo lobushushu be-granite. Ziziphi umahluko phakathi kweentlobo ezahlukeneyo zozinzo lobushushu be-granite?
