Emkhakheni wemishini yokulinganisa ngokunembile, ukunemba nokuzinza kwemishini kuhlobene ngqo nokunemba kwemiphumela yokulinganisa, futhi ukukhetha izinto zokuthwala nokusekela ithuluzi lokulinganisa kubalulekile. I-Granite ne-marble, njengezinto ezimbili ezivamile zamatshe ezisezingeni eliphezulu, zivame ukubhekwa njengokwakhiwa kwemishini yokulinganisa ngokunembile, kodwa yimuphi ongcono? Ake simbe ngokujulile.
Ukuqhathaniswa kokuqina
Ukuzinza kuyisisekelo semishini yokulinganisa ngokunembile. I-granite yakhiwa ijule kakhulu oqweqweni loMhlaba, ngemva kokushisa okuphezulu kanye nokucindezela okuphezulu isikhathi eside icisha, isakhiwo sangaphakathi siminyene futhi sifana. Izigidi zeminyaka yokuguga kwemvelo zenza ukucindezeleka kwayo kwangaphakathi kukhululwe ngokuphelele, okunikeza i-granite ukuzinza okuphezulu kakhulu. Lapho izici zemvelo ezifana nokushisa nomswakama zishintsha, ukuguquguquka kwe-granite kuncane kakhulu.
Ngokuphambene nalokho, imabula, yize nayo yakhiwa ngemva kwenqubo yesikhathi eside ye-geological, kodwa isakhiwo sayo sekristalu siqinile, futhi ukwakheka kwayo kuqukethe amaminerali amaningi njenge-calcium carbonate. Lezi zici zibangela ukuthi imabula ikhule noma inciphe kalula lapho ibhekene nezinguquko zemvelo. Isibonelo, endaweni enokushintshashintsha okukhulu kwezinga lokushisa, ushintsho losayizi wemabula lungaphazamisa ukunemba kokulinganisa kwemishini yokulinganisa ngokunembile, kuyilapho i-granite ingalondoloza ukuzinza kangcono futhi inikeze isisekelo esithembekile sezinsimbi zokulinganisa.
Ukuqina nokumelana nokuguguleka
Imishini yokulinganisa ngokunembile ekusetshenzisweni kwesikhathi eside kwale nqubo, ngokuqinisekile izohlushwa ukungqubuzana nokushayisana okuhlukahlukene. I-granite iqinile ngokuthungwa, futhi ubulukhuni bayo be-Mohs buvame ukuba cishe ngama-6-7, okungamelana ngempumelelo nokuguguleka kwangaphandle nokuklwebheka. Enkambisweni yokubekwa njalo nokunyakaza kwamathuluzi okulinganisa namasampula, ubuso be-granite akulula ukushiya amamaki asobala, ukuze kugcinwe ukuthamba nokunemba kwayo isikhathi eside.
Ubulukhuni bemabula buphansi kakhulu, kanti ubulukhuni be-Mohs buvame ukuba ngu-3-5. Lokhu kusho ukuthi ngaphansi kwezimo ezifanayo zokusetshenziswa, ubuso bemabula buthambekele kakhulu ekuklwebhekeni nasekugugeni, futhi uma ubushelelezi bomphezulu sebonakele, buzoba nomthelela omubi ekunembeni kwemishini yokulinganisa ngokunemba. Emishinini yokulinganisa edinga ukusebenza isikhathi eside, okunembile, ubulukhuni obuphezulu kanye nokumelana nokuguguleka kwe-granite ngokungangabazeki kuyisinqumo esingcono kakhulu.
Ukuhlaziywa kokumelana nokugqwala
Amakhemikhali ahlukahlukene angase abe khona endaweni yokulinganisa, njengokuguquguquka kwama-reagents e-acid-base, okuletha inselele ekumelaneni nokugqwala kwezinto zemishini. I-Granite yakhiwe kakhulu yi-quartz, i-feldspar kanye namanye amaminerali, izakhiwo zamakhemikhali zizinzile, zinokumelana okuhle kakhulu kwe-asidi, ukumelana ne-alkali. Ezindaweni eziyinkimbinkimbi zamakhemikhali, i-granite ingagcina izakhiwo zayo zomzimba nezamakhemikhali isikhathi eside ukuqinisekisa ukusebenza okuzinzile kwemishini yokulinganisa ngokunemba.
Ngenxa yomsebenzi wamakhemikhali wengxenye yayo eyinhloko ye-calcium carbonate, imabula ithambekele ekuphenduleni kwamakhemikhali lapho ihlangana nezinto ezine-asidi, okuholela ekugqwaleni nasekulimazeni ubuso. Lokhu kugqwala ngeke kuthinte kuphela ukubukeka kwemabula, kodwa futhi kuzobhubhisa ukuqina kwesakhiwo sayo, bese kuthinta ukunemba kwemishini yokulinganisa ngokunemba. Ngakho-ke, endaweni yokulinganisa lapho kunengozi yokugqwala kwamakhemikhali, ukumelana nokugqwala kwe-granite kwenza ibe yinto ethembeke kakhulu.
Ukuqina okuphelele, ubulukhuni kanye nokumelana nokuguguleka kanye nokumelana nokugqwala nezinye izici, i-granite ezinkombeni ezahlukahlukene ezibalulekile ibonise kangcono kunokusebenza kwemabula. Ngemishini yokulinganisa ngokunemba edinga ukunemba okuphezulu kanye nokuqina, i-granite ngokungangabazeki iyisinqumo esifaneleka kakhulu. Inganikeza isisekelo esizinzile nesithembekile sezinsimbi zokulinganisa, iqinisekise ukunemba nokuthembeka kwemiphumela yokulinganisa, futhi isize umsebenzi wokulinganisa ngokunemba ocwaningweni lwesayensi, ekukhiqizweni kwezimboni nakwezinye izinkambu ukuthi zisebenze kahle.
