Izingxenye zemishini ye-granite zisetshenziswa kakhulu ekucubunguleni imikhiqizo yedivayisi ngokunemba ngenxa yezakhiwo zazo ezinhle kakhulu njengokuqina okuphezulu, ukunwetshwa okushisayo okuphansi, kanye nekhono elihle kakhulu lokumanzisa.Kodwa-ke, njengazo zonke ezinye izinto zokwakha, aziphelele futhi zingase zibe neziphambeko ezidinga ukucatshangelwa ekwenzeni ukunemba kwemishini.
Esinye seziphambeko ezivame ukubonwa ezingxenyeni ze-granite ukwenzeka kokuphuka noma imifantu ebusweni.Lezi zinkinga zingabangelwa izici ezimbalwa ezinjengokulayisha ngokweqile, ukufakwa okungafanele, ukucindezela kokushisa, noma ukuchayeka endaweni enzima.Ukuvimbela lokhu, izingxenye kufanele zenzelwe i-geometry efanele kanye nokuqina kodonga, futhi izinyathelo ezanele kufanele zithathwe ukuvimbela ukulayisha ngokweqile noma ukucindezeleka okushisayo.
Esinye isici esingase sibe khona ezingxenyeni ze-granite ukwakheka kwama-pores nama-voids ebusweni noma ngaphakathi kwempahla ngokwayo.Lezi ziphambeko zinganciphisa ukwakheka futhi ziphazamise ukunemba komkhiqizo wokugcina.Ukukhethwa ngokucophelela nokuhlolwa kwezinto zokusetshenziswa, kanye nezinqubo zokuphulukisa ezifanele kungavimbela ukwakheka kwama-pores kanye nama-voids ezingxenyeni ze-granite.
Ngaphezu kwalokho, izakhi zegwadle zingase futhi zibonise ukuhluka kokucaba kwendawo noma i-perpendicularity yobuso ngokuhlobene nomunye nomunye.Lokhu kuhlukahluka kungavela ekuhlukeni kwemvelo kwezinto ezibonakalayo, kanye nenqubo yokukhiqiza.Ukuqinisekisa ukunemba komkhiqizo wokugcina, lokhu kuhluka kufanele kulinganiswe ngokucophelela futhi kunxeshezelwe phakathi nenqubo yomshini.
Okunye okungaba khona iphutha ezingxenyeni ze-granite ukuhluka kwama-coefficients wokunweba okushisayo kuyo yonke into.Lokhu kungabangela ukuntengantenga kwe-dimensional kanye nokuncipha kokunemba phezu kwebanga lokushisa.Ukuze kuncishiswe lo mphumela, onjiniyela bangase badizayine izingxenye ukuze banciphise ukuchezuka kwe-thermal, noma abakhiqizi bangasebenzisa ukwelashwa okushisayo ukuze bathole i-coefficient efanayo yokunwetshwa kwe-thermal kuyo yonke into.
Sekukonke, izingxenye ze-granite ziyizinto ezinhle kakhulu zokucubungula imikhiqizo yedivayisi ngokunemba, kodwa zingaba nokukhubazeka okungaba khona okudinga ukucatshangelwa nokuphathwa ngokucophelela.Ngokuqonda lezi zinkinga kanye nokuthatha izinyathelo ezifanele zokuzivimbela noma zokuzinciphisa, abakhiqizi bangakhiqiza izingxenye zekhwalithi ephezulu ezihlangabezana nezidingo zokunemba okuphezulu kwezimboni zesimanje.
