Iyini i-coefficient yokwandisa ye-granite? Izinga lokushisa lizinzile kangakanani?

I-coefficient yokwandisa eqondile ye-granite ivame ukuba cishe ku-5.5-7.5x10 - ⁶/℃. Kodwa-ke, ngezinhlobo ezahlukene ze-granite, i-coefficient yayo yokukhulisa ingase ihluke kancane.
I-Granite inokuqina okuhle kokushisa, okubonakala kakhulu kulezi zici ezilandelayo:
Ukuguquguquka okuncane kokushisa: ngenxa yokuguquguquka kwayo okuphansi kokukhula, ukuguquguquka kokushisa kwe-granite kuncane kakhulu uma izinga lokushisa lishintsha. Lokhu kuvumela izingxenye ze-granite ukuthi zigcine usayizi nesimo esizinzile ezindaweni ezahlukene zokushisa, okusiza ekuqinisekiseni ukunemba kwemishini yokunemba. Isibonelo, kumathuluzi okulinganisa anembe kakhulu, ukusetshenziswa kwe-granite njengesisekelo noma ibhentshi lokusebenzela, noma ngabe izinga lokushisa elizungezile linokuguquguquka okuthile, ukuguquguquka kokushisa kungalawulwa ngebanga elincane, ukuze kuqinisekiswe ukunemba kwemiphumela yokulinganisa.
Ukumelana okuhle nokushaqeka kokushisa: I-Granite ingamelana nezinga elithile lokushintsha kwezinga lokushisa okusheshayo ngaphandle kwemifantu noma umonakalo osobala. Lokhu kungenxa yokuthi inomoya omuhle wokushisa kanye namandla okushisa, okungadlulisa ukushisa ngokushesha nangokulinganayo lapho izinga lokushisa lishintsha, kunciphisa ukuhlushwa kokucindezeleka kokushisa kwangaphakathi. Isibonelo, kwezinye izindawo zokukhiqiza zezimboni, lapho imishini iqala noma iyeka ukusebenza ngokuzumayo, izinga lokushisa lizoshintsha ngokushesha, futhi izingxenye ze-granite zingazivumelanisa kangcono nalokhu kushaqeka kokushisa futhi zigcine ukuzinza kokusebenza kwazo.
Ukuzinza okuhle kwesikhathi eside: Ngemva kwesikhathi eside sokuguga kwemvelo kanye nesenzo se-geological, ukucindezeleka kwangaphakathi kwe-granite kuye kwakhululwa ngokuyisisekelo, futhi isakhiwo sizinzile. Enqubweni yokusetshenziswa kwesikhathi eside, ngisho nangemva kokushintsha kwemijikelezo yokushisa eminingi, isakhiwo saso sangaphakathi akulula ukusishintsha, singaqhubeka nokugcina ukuzinza okuhle kokushisa, sinikeze ukwesekwa okuthembekile kwemishini enembile kakhulu.
Uma kuqhathaniswa nezinye izinto ezivamile, ukuzinza kokushisa kwe-granite kusezingeni eliphezulu, okulandelayo ukuqhathanisa phakathi kwezinto ze-granite nezensimbi, izinto zobumba, izinto ezihlanganisiwe ngokuya ngokuzinza kokushisa:
   Uma kuqhathaniswa nezinto zensimbi:

I-coefficient yokwanda kokushisa kwezinto zensimbi ezijwayelekile inkulu kakhulu. Isibonelo, i-coefficient yokwanda okuqondile kwensimbi yekhabhoni evamile icishe ibe ngu-10-12x10 - ⁶/℃, kanti i-coefficient yokwanda okuqondile kwe-aluminium alloy icishe ibe ngu-20-25x10 - ⁶/℃, ephakeme kakhulu kune-granite. Lokhu kusho ukuthi lapho izinga lokushisa lishintsha, usayizi wezinto zensimbi ushintsha kakhulu, futhi kulula ukukhiqiza ukucindezeleka okukhulu kwangaphakathi ngenxa yokwanda kokushisa kanye nokufinyela okubandayo, ngaleyo ndlela kuthinte ukunemba nokuqina kwayo. Usayizi we-granite uyashintsha kancane lapho izinga lokushisa lishintsha, okungagcina kangcono isimo sokuqala nokunemba. Ukuqhuba kokushisa kwezinto zensimbi kuvame ukuba phezulu, futhi enkambisweni yokushisa noma ukupholisa okusheshayo, ukushisa kuzoqhutshwa ngokushesha, okuholela ekwehlukeni okukhulu kokushisa phakathi kwangaphakathi kanye nobuso bezinto, okuholela ekucindezelekeni kokushisa. Ngokuphambene nalokho, ukuqhuba kokushisa kwe-granite kuphansi, futhi ukuqhuba kokushisa kuhamba kancane, okunganciphisa ukukhiqizwa kokucindezeleka kokushisa ngezinga elithile futhi kubonise ukuzinza okungcono kokushisa.

Uma kuqhathaniswa nezinto zobumba:

I-coefficient yokwandisa ukushisa kwezinye izinto ze-ceramic ezisebenza kahle ingaba phansi kakhulu, njenge-silicon nitride ceramics, i-coefficient yayo yokukhulisa eqondile icishe ibe ngu-2.5-3.5x10 - ⁶/℃, ephansi kune-granite, futhi inezinzuzo ezithile ekuzinzeni kokushisa. Kodwa-ke, izinto ze-ceramic zivame ukuqhekeka, ukumelana nokushaqeka kokushisa kuphansi kakhulu, futhi ukuqhekeka noma ngisho nokuqhekeka kulula ukwenzeka lapho izinga lokushisa lishintsha kakhulu. Nakuba i-coefficient yokwandisa ukushisa ye-granite iphakeme kancane kunezinye izinto ze-ceramics ezikhethekile, inokuqina okuhle kanye nokumelana nokushaqeka kokushisa, ingamelana nezinga elithile lokushintsha kwezinga lokushisa, ekusetshenzisweni okusebenzayo, ezindaweni eziningi zokushintsha kwezinga lokushisa okungekubi kakhulu, ukuzinza kokushisa kwe-granite kungahlangabezana nezidingo, futhi ukusebenza kwayo okuphelele kulinganisela kakhulu, izindleko ziphansi kakhulu.

Uma kuqhathaniswa nezinto ezihlanganisiwe:

Ezinye izinto ezihlanganisiwe ezithuthukisiwe zingafinyelela i-coefficient ephansi yokwanda kokushisa kanye nokuzinza okuhle kokushisa ngokuklama okunengqondo kokuhlanganiswa kwe-fiber kanye ne-matrix. Isibonelo, i-coefficient yokwanda kokushisa kwezinto ezihlanganisiwe eziqinisiwe ze-carbon fiber ingalungiswa ngokuya ngesiqondiso nokuqukethwe kwe-fiber, futhi ingafinyelela amanani aphansi kakhulu kwezinye izindlela. Kodwa-ke, inqubo yokulungiselela izinto ezihlanganisiwe iyinkimbinkimbi futhi izindleko ziphezulu. Njengezinto zemvelo, i-granite ayidingi inqubo yokulungiselela eyinkimbinkimbi, futhi izindleko ziphansi kakhulu. Nakuba ingase ingabi yinhle njengezinye izinto ezihlanganisiwe eziphezulu kwezinye izinkomba zokuqina kokushisa, inezinzuzo maqondana nokusebenza kwezindleko, ngakho-ke isetshenziswa kabanzi ezinhlelweni eziningi ezivamile ezinezidingo ezithile zokuqina kokushisa. Kuziphi izimboni lapho kusetshenziswa khona izingxenye ze-granite, ukuzinza kokushisa kuyinto ebalulekile? Nikeza idatha ethile yokuhlola noma izimo zokuzinza kokushisa kwe-granite. Yimiphi umehluko phakathi kwezinhlobo ezahlukene zokuzinza kokushisa kwe-granite?
