Luthini uluhlu loxinano lwezinto zegranite ezichanekileyo?

Izinto zegranite ezichanekileyo zisetyenziswa kakhulu kumashishini ahlukeneyo, kuquka i-aerospace, iimoto, izixhobo ze-elektroniki, kunye nemveliso. Zifunwa kakhulu ngenxa yokuqina kwazo okumangalisayo, ukuzinza, kunye nokukwazi ukumelana nobushushu obugqithisileyo. Ezi zinto zegranite ezikhethekileyo ziyinxalenye ebalulekileyo yeenkqubo ezininzi ezibalulekileyo, kwaye ukwenziwa kwazo kufuna ukuchaneka okuphezulu. Uxinano lwezinto zegranite ezichanekileyo zidlala indima ebalulekileyo ekumiseleni ukuthembeka kwesakhiwo sazo kunye nokukwazi kwazo ukumelana noxinzelelo ngexesha lokusebenza.

Uluhlu loxinano lwezinto zegranite ezichanekileyo luyahluka ngokusekelwe kwisicelo sazo esithile. Ngokubanzi, izinto zegranite ezichanekileyo zinoxinano oluqala kwi-2.5 g/cm3 ukuya kwi-3.0 g/cm3. Izinto zegranite ezisetyenziselwa ukwenza ezi zinto zihlala zikhethwa ngokusekelwe kwiimpawu zazo zomzimba, ezinje ngamandla okucinezelwa, ubulukhuni, kunye nokuzinza kobushushu. Uluhlu loxinano lumiselwa ziimpawu zezinto zegranite ezithile kunye nenkqubo yokuvelisa esetyenziselwa ukwenza into.

I-Granite yinto yendalo eyenziwe kakhulu yi-quartz, i-feldspar, kunye ne-mica. Ukudibana kwezi zimbiwa kunika i-granite iimpawu zayo ezikhethekileyo, kubandakanya uxinano lwayo oluphezulu, amandla, kunye nokuqina. Inkqubo yokuvelisa esetyenziselwa ukwenza izinto ze-granite ezichanekileyo ibandakanya ukusika, ukugaya, kunye nokupolisha izinto ze-granite ngokwemilinganiselo efunekayo. Ngexesha lenkqubo yokuvelisa, uxinano lwezinto ze-granite lungatshintshwa ngokongeza okanye ukususa izinto kwiindawo ezithile ukuze kufezekiswe ubunzima kunye nobukhulu obufunekayo.

Uluhlu loxinano lwezixhobo zegranite ezichanekileyo lubalulekile kuba lumisela ukuqina kwesakhiwo sazo kunye nokukwazi kwazo ukumelana noxinzelelo. Izixhobo zegranite ezinoxinano oluphezulu zihlala ixesha elide kwaye zinokumelana noxinzelelo oluphezulu kunezixhobo ezinoxinano oluphantsi. Abavelisi basebenzisa iindlela ezahlukeneyo ukuvavanya uxinano lwezixhobo zegranite, kubandakanya ubunzima be-hydrostatic, umgaqo we-Archimedes, kunye ne-mass spectrometry.

Ukongeza kuxinano lwazo, izinto zegranite ezichanekileyo ziyaziwa nangokuzinza kwazo okugqwesileyo. Igranite sisithinteli-bushushu esibalaseleyo, oko kuthetha ukuba ayikhuli okanye ayinciphisi kakhulu xa kuphendulwa utshintsho lobushushu. Oku kuyenza ilungele ukusetyenziswa kwizicelo ezifuna uzinzo oluphezulu, njengezixhobo zokulinganisa ngokuchanekileyo kunye noomatshini bemizi-mveliso. Uzinzo oluphezulu lwezinto zegranite ezichanekileyo zivumela ukuba zigcine imo yazo kunye nokusebenza kwazo ngokuhamba kwexesha, nto leyo ekhokelela ekuchanekeni okukhulu kunye nemveliso.

Ukuqukumbela, uluhlu loxinano lwezinto zegranite ezichanekileyo yinto ebalulekileyo emisela ukuqina kwazo kunye nokukwazi kwazo ukumelana noxinzelelo. Ezi zinto zenziwe kusetyenziswa izixhobo zegranite ezikumgangatho ophezulu ezikhethwa ngokusekelwe kwiimpawu zazo zomzimba kwaye emva koko zisikwe, zigaywe, kwaye zipolishwe ngokwemilinganiselo efunekayo. Uxinano lwezinto zegranite ezichanekileyo ludla ngokuba phakathi kwe-2.5 g/cm3 ukuya kwi-3.0 g/cm3. Ezi zinto zisetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanya i-aerospace, iimoto, izixhobo ze-elektroniki, kunye nemveliso, kwaye zaziwa ngokuqina kwazo okugqwesileyo, ukuzinza, kunye nokukwazi ukumelana nobushushu obugqithisileyo.
