Ukukhethwa kwezinto ezisisiseko kudlala indima ebalulekileyo ekwakhiweni kweemodyuli zokuhamba ngokuchanekileyo kakhulu. Iziseko zokuchaneka kwegranite kunye neziseko zokuphosa izimbiwa, njengeendlela ezimbini eziphambili, nganye ineempawu ezahlukileyo ezahluke kakhulu ngokubhekiselele kuzinzo, ukugcinwa kokuchaneka, ukuqina, kunye neendleko.
Uzinzo: Uxinano lwendalo xa kuthelekiswa nezinto ezidityanisiweyo ezenziweyo
Emva kwezigidi zeminyaka yokuguqulwa kwejoloji, i-granite yenza isakhiwo esixineneyo nesifanayo ngokusebenzisa ukubopha kwendalo kwe-quartz, i-feldspar, kunye nezinye izimbiwa. Kwiindawo zoshishino apho izixhobo ezinkulu zivelisa ukungcangcazela okunamandla, isakhiwo sekristale esintsonkothileyo se-granite sinciphisa ngempumelelo ezi ziphazamiso, sinciphisa ubukhulu bokungcangcazela obudluliselwa kwiimodyuli zentshukumo ezintanta emoyeni ngaphezulu kwe-80%. Oku kuqinisekisa ukusebenza kakuhle ngexesha lemisebenzi yokucubungula okanye yokuhlola ngokuchanekileyo, njengokwenziwa kweepateni ezichanekileyo zeetships ze-elektroniki kwiinkqubo ze-photolithography.
Iziseko zokuphosa izimbiwa zenziwe ngamasuntswana ezimbiwa ezixutywe nee-binders ezikhethekileyo, nto leyo ebangela ulwakhiwo lwangaphakathi olufanayo oluneempawu ezilungileyo zokudambisa ukungcangcazela. Nangona zibonelela nge-buffering esebenzayo yokungcangcazela ngokubanzi kwaye zidala indawo yokusebenza ezinzileyo yeemodyuli zentshukumo ezintantayo emoyeni, ukusebenza kwazo phantsi kokungcangcazela okunamandla aphezulu, okuqhubekekayo kungaphantsi kancinci kunokweziseko zegranite. Olu thintelo lunokubangela ukungachaneki okuncinci kwizicelo zokuchaneka okuphezulu.
Ukugcinwa Kokuchaneka: Ukwandiswa okuphantsi kwendalo xa kuthelekiswa nokucutheka okulawulwayo
I-Granite yaziwa ngokuba ne-coefficient ephantsi kakhulu yokwanda kobushushu (ngesiqhelo yi-5–7 × 10⁻⁶/°C). Nokuba kwiindawo ezinokuguquguquka okukhulu kobushushu, iziseko zokuchaneka kwe-granite zibonisa utshintsho oluncinci kakhulu. Umzekelo, kwizicelo zeenkwenkwezi, iimodyuli zokuhamba ezisebenzisa umoya othambileyo osekelwe kwi-granite ziqinisekisa ukuchaneka kokubeka ilensi kwinqanaba le-submicron kwiiteleskopu, okuvumela izazi ngeenkwenkwezi ukuba zibambe iinkcukacha ezintsonkothileyo zezinto ezikude zasezulwini.
Izinto zokuphosa izimbiwa zinokwenziwa ukuze zilungele kwaye zilawule iimpawu zokwandiswa kobushushu, zifezekise ii-coefficients ezilingana okanye ezingaphantsi kwezo ze-granite. Oku kuzenza zifaneleke kwizixhobo zokulinganisa ubushushu obuphezulu ezibuthathaka. Nangona kunjalo, ukuzinza kwexesha elide kokuchaneka kwazo kuhlala kuxhomekeke ekuqinisekisweni ngenxa yezinto ezifana nokuguga kwe-binder, okunokukhokelela ekuncipheni kokusebenza ngexesha elide lokusetyenziswa.
Ukuqina: Ukuqina okuphezulu kwelitye lendalo xa kuthelekiswa nezinto ezidinwayo
Ubunzima obuphezulu beGranite (isikali seMohs: 6–7) bubonelela ngokumelana nokuguguleka okugqwesileyo. Kwiilabhoratri zesayensi yezinto, iziseko zegranite zeemodyuli zokuhamba ezisetyenziswa rhoqo emoyeni ezibhabhayo zimelana nokungqubana okude okuvela kwizilayida, nto leyo eyandisa imijikelo yolondolozo ngaphezu kwe-50% xa kuthelekiswa neziseko zesiqhelo. Nangona le nzuzo injalo, ukuguguleka kwegranite kubeka umngcipheko wokuqhekeka xa kuthe kwagaleleka ngengozi.
Iziseko zokuphosa iminerali zibonisa iipropati eziphezulu zokulwa nokudinwa, zigcina ulungelelwaniso lwesakhiwo ngexesha lokuhamba okuphindaphindiweyo kweemodyuli ezibhabhayo ngomoya ngokuchanekileyo. Ukongeza, zibonisa ukumelana nokubola okuncinci kweekhemikhali, okwandisa ukuqina kwiindawo ezinokonakala kancinci. Nangona kunjalo, kwiimeko eziqatha ezifana nokufuma okuphezulu, i-binder ngaphakathi kweziseko zokuphosa iminerali inokonakala, ibeke emngciphekweni ukuqina kwayo iyonke.
Iindleko Zokuvelisa Nobunzima Bokucubungula**: Imingeni yokukhupha amatye endalo xa kuthelekiswa neenkqubo zokwenziwa
Ukwembiwa kwegranite kunye nokuthuthwa kwayo kubandakanya uthutho oluntsonkothileyo, ngelixa ukucubungula kwayo kufuna izixhobo kunye neendlela eziphucukileyo. Ngenxa yobunzima bayo obuphezulu kunye nokuqhekeka, imisebenzi efana nokusika, ukugaya, kunye nokupolisha idla ngokukhokelela kumaxabiso aphezulu enkunkuma, nto leyo enyusa iindleko zokuvelisa.
Ngokwahlukileyo koko, ukuveliswa kweziseko zokubumba izimbiwa kufuna iimolds ezithile kunye neenkqubo ezithile. Nangona uphuhliso lokuqala lwemold lubangela iindleko ezinkulu, ukuveliswa kobuninzi okulandelayo kuba yingenelo ngokwezoqoqosho xa imold imiselwe.
