Amapharamitha wezobuchwepheshe kanye namazinga we-granite mehendi.

 

I-Granite isikhathi eside yaqashelwa njengezinto zikaNdunankulu zezisekelo zemishini ngenxa yezakhiwo zayo ezihlukile, kufaka phakathi ubukhulu obuphakeme, ukuqina, kanye nokumelana nokwanda okushisayo. Ukuqonda amapharamitha wezobuchwepheshe kanye namazinga ahambisana nezisekelo zemishini ye-granite kubalulekile kunjiniyela kanye nabakhiqizi abathembele ngokunemba nokuqina kuzicelo zabo.

Enye yamapharamitha wezobuchwepheshe aphambili we-Granite Mehemu Amandla amandla ayo acindezela, avela ngokujwayelekile kusuka ku-100 kuye ku-300 MPA. La mandla aphezulu acindezelayo aqinisekisa ukuthi i-granite ingamelana nemithwalo ebalulekile ngaphandle kokuwohloka, okwenza kube kuhle ukusekela imishini esindayo nemishini. Ngokwengeziwe, ama-granite ekhombisa ama-coefficients aphansi aphansi, ngokuvamile azungeze ama-5 kuye kwayi-7 x 10

I-Surfavil Flatness ingenye indinganiso ebucayi yezisekelo zemishini e-granite. Ukubekezelelana kweflethi ukubekezelela kuvame ukucaciswa kuma-micrometer, ngezicelo eziphezulu ezidinga ukubekezelelana njenge-0,005 mm ngemitha ngayinye. Leli zinga lokunemba libalulekile kwizicelo ezinjengokuxhumanisa imishini yokulinganisa (CMMS) namadivayisi abonakalayo, lapho ukuphambuka okuncane kungaholela emaphutheni aphansi wokulinganisa.

Ngaphezu kwalokho, ubuningi be-granite ngokuvamile buqala kusuka ku-2.63 kuya ku-2.75 g / cm³, kufaka isandla ekuzinzeni kwayo kanye nokudliwa kwezakhiwo. Lezi zici zibalulekile ekunciphiseni umthelela wokudlidliza kwangaphandle, ngaleyo ndlela ethuthukisa ukunemba kwezinsimbi ezibucayi ezibekwe ezisekelweni ze-granite.

Ekuphetheni, amapharamitha wezobuchwepheshe kanye namazinga ezisekelo zemishini yamagogo adlala indima ebaluleke kakhulu kwizimboni ezahlukahlukene. Ngokunamathela kulezi zinto ezichaziwe, abakhiqizi bangaqinisekisa ukuthembeka nokwenza imisebenzi yabo, kuholele ekusebenzeni kahle kokusebenza nokunemba ezinhlelweni zokukhiqiza. Njengoba ubuchwepheshe buthuthuka, isidingo sezisekelo ezisezingeni eliphakeme zemishini zizoqhubeka nokukhula, zigcizelela ukubaluleka kokuqonda la mazinga ezobuchwepheshe.
