Iipleyiti zomphezulu wegranite zibaluleke kakhulu ekulinganisweni ngokuchanekileyo, ezisetyenziswa kakhulu kwiilebhu nakwiindawo zokwenza izinto njengeziseko zokujonga izixhobo, izixhobo ngokuchanekileyo, kunye nezinto zoomatshini. Zenziwe ngegranite yendalo esemgangathweni ophezulu, ezi pleyiti zidibanisa iingenelo ezibonakalayo zelitye kunye nozinzo olubalaseleyo, zibonelela ngokusebenza okuphezulu kwiipleyiti zesinyithi zemveli.
Ipleyiti nganye yomphezulu wegranite iveliswa ngokudityaniswa koomatshini abachanekileyo kunye nokusila ngesandla ngononophelo, ngokuqhelekileyo kwindawo yobushushu obungaguqukiyo ukuqinisekisa ukuchaneka okuphezulu. Isiphumo kukuba umphezulu osebenzayo ogudileyo, othe tyaba onesakhiwo esincinci, ukukhanya okumnyama, kunye nobume obufanayo. Olu dibaniso lobuhle kunye nokuchaneka lwenza igranite ibe yinto engenakutshintshwa yomsebenzi wokulinganisa ngokuchanekileyo kunye nomsebenzi wokulinganisa.
Ukuze kufezekiswe kwaye kugcinwe ukuchaneka okunjalo, iipleyiti zomphezulu wegranite kufuneka zihlangabezane nemigangatho engqongqo yezinto kunye neyokwenziwa. Ilitye elisetyenzisiweyo kufuneka libe lincinci kwaye lixineneyo—ngokuqhelekileyo i-gabbro, i-diabase, okanye i-granite emnyama—elinomxholo we-biotite ongaphantsi kwe-5%, ukufunxwa kwamanzi ngaphantsi kwe-0.25%, kunye ne-modulus elastiki edlula i-0.6 × 10⁻⁴ kg/cm². Ubulukhuni bomphezulu kufuneka bube ngaphezulu kwe-70 HS ukuqinisekisa ukumelana nokuguguleka okuhle. Ngexesha lokuveliswa, umphezulu osebenzayo kufuneka ungabi nazimfanta, iimbobo, imingxunya yomoya, okanye izinto ezifakwe kwi-slag. Iziphene ezincinci zobuhle ezingachaphazeli ukuchaneka zinokwamkeleka, kodwa nasiphi na isiphene kumphezulu wokulinganisa esinokuchaphazela iziphumo asivumelekanga ngokungqongqo.
Ngokungafaniyo neepleyiti zesinyithi eziphosiweyo, iipleyiti zomphezulu wegranite azinamagnethi, azinamhlwa, kwaye azichaphazeleki kukutshintsha kobushushu okanye ukufuma. Zihlala zithe tyaba xa zisetyenziswa ixesha elide kwaye azinamhlwa okanye ziguquguquke. Nokuba zitshatyalaliswa, igranite inokuqhekeka kancinci ngaphandle kokuchaphazela ukuthembeka okanye ukuchaneka komphezulu. Oku kuhlala ixesha elide kunika igranite ithuba elifanelekileyo kwiindawo ezifuna umlinganiselo ozinzileyo nochanekileyo.
Kwiipleyiti zomphezulu ezikumgangatho ophezulu, ezifana neGrade 000 kunye neGrade 00, iimpawu zokuphatha ezifana neziphatho zokuphakamisa azikhuthazwa rhoqo ukuze kuthintelwe ukuchaneka komphezulu wokusebenza. Ukuba kufuneka izinto zokufaka okanye imingxunya enemisonto kwiipleyiti zeGrade 0 okanye zeGrade 1, ubunzulu bazo kufuneka buhlale bungaphantsi komphezulu womhlaba ukuthintela ukugqwetheka. Uburhabaxa bomphezulu obuvumelekileyo (Ra) bomphezulu wokusebenza buhlala buphakathi kwe-0.32 kunye ne-0.63 μm, ngelixa amacala anokufikelela kwi-10 μm. Ukongeza, ukunyamezelana kokuma kwamacala akufutshane kuhambelana nomgangatho we-GB/T1184 Grade 12, okuqinisekisa ubudlelwane obuchanekileyo bejometri kuzo zonke iindawo zokulinganisa.
Ukusetyenziswa nokugcinwa ngokufanelekileyo kubalulekile ekugcineni ukuchaneka kweepleyiti zomphezulu wegranite. Zifanele zisetyenziswe kwindawo ecocekileyo, elawulwa bubushushu, zikhuselwe kwimpembelelo, kwaye zicocwe rhoqo ukususa uthuli kunye nenkunkuma. Xa ziphathwa ngokuchanekileyo, iipleyiti zomphezulu wegranite zibonelela ngozinzo olungenakuthelekiswa nanto kunye nobude bexesha, zisebenza njengesiseko esithembekileyo sokulinganisa nokuhlola ngokuchanekileyo kushishino lwanamhlanje.
Apha e-ZHHIMG, sigxile ekuveliseni nasekulinganiseni iipleyiti zomphezulu wegranite ezichanekileyo ezihlangabezana nemigangatho yamazwe ngamazwe. Iinkqubo zethu zokuvelisa eziphambili, ulawulo oluqinileyo lomgangatho, kunye nemveliso eqinisekisiweyo yi-ISO ziqinisekisa ukuba ipleyiti nganye yegranite inika ukuchaneka okuhlala ixesha elide kunye nokusebenza okuthenjwa ziinjineli kunye neelabhoratri kwihlabathi liphela.
