Ekukhetheni iindawo zesakhiwo, amandla okuxinanisa ezinto zesakhiwo abaluleke kakhulu. Njengezixhobo ezimbini zesakhiwo eziqhelekileyo, amalungu e-precision granite kunye namalungu e-precision ceramic abonisa iimpawu ezahlukeneyo kumandla okuxinanisa, ezinefuthe elikhulu ekukhetheni nasekusetyenzisweni kweendawo zesakhiwo.
Uthelekiso lwamandla oxinzelelo
Izixhobo zegranite ezichanekileyo:
I-granite echanekileyo njengelitye lendalo, amandla ayo okuxinanisa aphezulu kakhulu. Ngokubanzi, amandla okuxinanisa e-granite anokufikelela kumakhulu ee-megapascals (MPa) nangaphezulu, nto leyo eyenza ukuba isebenze kakuhle phantsi kwemithwalo yoxinzelelo. Amandla aphezulu okuxinanisa e-granite ngokuyintloko ngenxa yesakhiwo sayo sekristale esixineneyo kunye nobunzima obuphezulu, okwenza i-granite ibe yinto efunekayo kubunjineli bezakhiwo ezinzima njengezakhiwo, iiBhulorho kunye neendlela.
Izixhobo ze-ceramic ezichanekileyo:
Ngokwahlukileyo koko, izinto zeseramikhi ezichanekileyo nazo zisebenza kakuhle kumandla okuxinanisa, kodwa ixabiso elithile liya kuchaphazeleka zizinto ezifana nokwakheka kwezinto kunye nenkqubo yokulungiselela. Ngokubanzi, amandla okuxinanisa eseramikhi ezichanekileyo anokufikelela kumawaka eemegapascals (MPa) okanye ngaphezulu. La mandla aphezulu abangelwa ikakhulu yisakhiwo sekristale esixineneyo ngaphakathi kwezinto zeseramikhi kunye nebhondi enamandla ye-ionic, ibhondi ye-covalent kunye nezinye iibhondi zeekhemikhali. Nangona kunjalo, kufuneka kuqatshelwe ukuba nangona amandla okuxinanisa eseramikhi ezichanekileyo ephezulu, amandla ayo okuxinana kunye namandla okucheba aphantsi kakhulu, kwaye ukubhitya kwayo kukhulu, okuthintela ukusetyenziswa kwayo kwezinye iindawo ukuya kwinqanaba elithile.
Impembelelo ekukhetheni iindawo zesakhiwo
Iingqwalasela zesimo sesicelo:
Xa ukhetha izinto zokwakha, kufuneka wazi imeko yesicelo kunye neemfuno ezithile. Kwiimeko apho kufuneka zimelane nemithwalo yoxinzelelo olukhulu, njengeeBridges, iitunnels, izakhiwo eziphakamileyo kunye nezinye iiprojekthi zezakhiwo ezinzima, izinto zegranite ezichanekileyo ziba lukhetho lokuqala ngenxa yamandla azo aphezulu okuxinzelela kunye nokuqina okuhle. Kwezinye iimeko apho kufuneka ukuchaneka okuphezulu kunye nozinzo, njengezixhobo zokulinganisa ngokuchanekileyo, izixhobo ze-semiconductor kunye nezinye iindawo, izinto ze-ceramic ezichanekileyo ziyathandwa ngenxa yobushushu bazo obuphezulu kunye ne-coefficient ephantsi yokwandisa ubushushu.
Ibhalansi yeendleko kunye neenzuzo:
Ukongeza ekuqwalaseleni amandla okuxinwa kwezinto, kubalulekile ukuqwalasela ngokupheleleyo izinto ezifana neendleko, ubunzima bokucubungula, kunye neendleko zokugcina. Nangona icandelo le-precision granite linamandla aphezulu okuxinwa, kunzima ukulicubungula kwaye ixabiso liphezulu. Nangona icandelo le-precision ceramic lineempawu ezininzi ezintle, inkqubo yalo yokulungiselela iyinkimbinkimbi kwaye ixabiso liphezulu. Ke ngoko, xa ukhetha iindawo zokwakha, kuyimfuneko ukwenza urhwebo kunye norhwebo ngokweemfuno zokwenyani kunye neemeko zoqoqosho.
Uthelekiso lwentsebenzo epheleleyo:
Xa kukhethwa iindawo zokwakha, kuyimfuneko ukwenza uthelekiso olupheleleyo lweempawu ezipheleleyo zezinto zokwakha. Ukongeza kumandla okuxinzelela, kuyimfuneko ukuqwalasela amandla okuxinana, amandla okucheba, ubulukhuni, ukumelana nokugqwala, ukuzinza kobushushu kunye nezinye iimpawu zezinto zokwakha. Izinto zegranite ezichanekileyo zibalaseleyo kumandla okuxinzelela kunye nokuqina, kodwa zimbi kakhulu kubunzima bazo. Izinto zeseramikhi ezichanekileyo zine-insulation egqwesileyo, i-thermal expansion coefficient ephantsi kunye nokumelana nokugqwala, kodwa kukho imingeni ethile kubuthathaka kunye nobunzima bokucubungula. Ke ngoko, xa kukhethwa iindawo zokwakha, kufuneka kuqwalaselwe kwaye kukhethwe ngokubanzi ngokweemfuno ezithile.
Ngamafutshane, izinto zegranite echanekileyo kunye nezinto zeseramikhi echanekileyo zinezibonelelo zazo kumandla okuxinzelela, nto leyo enefuthe elibalulekileyo ekukhetheni izinto zesakhiwo. Kwizicelo ezisebenzayo, kufuneka kuqwalaselwe kwaye kukhethwe ngokubanzi ngokweemfuno ezithile kunye neemeko ukuqinisekisa ukhuseleko, ukuthembeka kunye nengqiqo yezoqoqosho yeendawo zesakhiwo.
