Amapuleti obuso be-granite ayitshe lesisekelo lokulinganisa ngokunemba, asetshenziswa kabanzi emalabhorethri nasezindaweni zokukhiqiza njengezisekelo zokubhekisela ekuhloleni amathuluzi, amathuluzi okunemba, kanye nezingxenye zemishini. Enziwe nge-granite yemvelo esezingeni eliphezulu, lawa mapuleti ahlanganisa izinzuzo ezibonakalayo zetshe nokuqina okumangalisayo kobukhulu, anikeza ukusebenza okuphezulu kumapuleti ensimbi ensimbi yendabuko.
Ipuleti ngalinye lobuso begranite likhiqizwa ngokuhlanganiswa komshini wokulungisa ngokunemba kanye nokugaya ngesandla ngokucophelela, ngokuvamile endaweni yokushisa engaguquki ukuqinisekisa ukunemba okuphezulu. Umphumela uba indawo yokusebenza ebushelelezi, eyisicaba enesakhiwo esicolekile, ukukhanya okumnyama, kanye nokuthungwa okufanayo. Lokhu kuhlanganiswa kobuhle nokunemba kwenza igranite ibe yinto engenakufakwa esikhundleni somsebenzi wokulinganisa nokulinganisa ngokunemba okuphezulu.
Ukuze kufezwe futhi kugcinwe ukunemba okunjalo, amapuleti obuso be-granite kumele ahlangabezane nezindinganiso eziqinile zezinto zokwakha kanye nokukhiqiza. Itshe elisetshenziswayo kufanele libe nohlamvu oluncane futhi lube lukhuni—ngokuvamile i-gabbro, i-diabase, noma i-granite emnyama—ngokuqukethwe kwe-biotite okungaphansi kuka-5%, ukumuncwa kwamanzi ngaphansi kuka-0.25%, kanye ne-modulus enwebekayo edlula u-0.6 × 10⁻⁴ kg/cm². Ubulukhuni bobuso kumele bube ngaphezu kuka-70 HS ukuqinisekisa ukumelana okuhle kokuguguleka. Ngesikhathi sokukhiqiza, ubuso bokusebenza kumele bungabi nemifantu, ama-dents, imigodi yomoya, noma ukufakwa kwe-slag. Amaphutha amancane okuhlenga angathinti ukunemba angamukeleka, kodwa noma yikuphi ukushiyeka ebusweni bokulinganisa okungathinta imiphumela akuvunyelwe ngokuphelele.
Ngokungafani namapuleti ensimbi ephothiwe, amapuleti ongaphezulu e-granite awanamandla kazibuthe, amelana nokugqwala, futhi awathinteki ukushintshashintsha kwezinga lokushisa noma umswakama. Agcina ubushelelezi ngaphezu kokusetshenziswa isikhathi eside futhi awakwazi ukugqwala noma ukuguquka. Ngisho noma eshaywa, i-granite ingaqhekeka kancane ngaphandle kokuthinta ubuqotho noma ukunemba kobuso. Lokhu kuqina kunikeza i-granite inzuzo eyinhloko ezindaweni ezidinga ukulinganiswa okuzinzile nokunembile.
Kumapuleti aphezulu, njengeBanga 000 kanye neBanga 00, izici zokuphatha njengezibambo zokuphakamisa ngokuvamile azinconywa ukuze kugwenywe ukuthonya ukunemba kwendawo yokusebenza. Uma kudingeka ukufakwa noma imifantu enezintambo kumapuleti eBanga 0 noma eBanga 1, ukujula kwawo kumele kuhlale ngaphansi kwendawo yokusebenza ukuze kuvinjelwe ukuphambuka. Ubulukhuni bomphezulu obuvumelekile (i-Ra) bomphezulu osebenzayo ngokuvamile buphakathi kuka-0.32 no-0.63 μm, kuyilapho izinhlangothi zingafinyelela ku-10 μm. Ngaphezu kwalokho, ukubekezelelana kokuma kwezinhlangothi eziseduze kuhambisana nezinga le-GB/T1184 leBanga 12, okuqinisekisa ubudlelwano obuqondile bejometri kuzo zonke izindawo zokulinganisa.
Ukusetshenziswa nokugcinwa okufanele kubalulekile ekulondolozweni kokunemba kwamapuleti ongaphezulu kwe-granite. Kufanele asetshenziswe endaweni ehlanzekile, elawulwa amazinga okushisa, avikelwe ekushayweni, futhi ahlanzwe njalo ukuze kususwe uthuli kanye nemfucumfucu. Uma ephathwa kahle, amapuleti ongaphezulu kwe-granite anikeza ukuzinza okungalingani kanye nokuphila isikhathi eside, esebenza njengesisekelo esithembekile sokulinganisa nokuhlola okunembile embonini yanamuhla.
Kwa-ZHHIMG, sigxile ekukhiqizweni nasekulinganisweni kwamapuleti obuso be-granite anembile ahlangabezana nezindinganiso zomhlaba wonke. Izinqubo zethu zokukhiqiza ezithuthukisiwe, ukulawulwa kwekhwalithi okuqinile, kanye nokukhiqizwa okuqinisekiswe yi-ISO kuqinisekisa ukuthi ipuleti ngalinye le-granite linikeza ukunemba nokusebenza okuhlala njalo okuthenjwa onjiniyela kanye nama-laboratory emhlabeni jikelele.
