Sekungamashumi eminyaka, umkhakha wobunjiniyela bokucacisa emhlabeni wonke uqonda izinzuzo ezingenakuphikwa zokusebenzisa i-granite ngaphezu kwezinto zendabuko ezifana nensimbi ephonswe noma insimbi ukuze kusetshenziswe i-metrology ebalulekile kanye nezisekelo zamathuluzi omshini. Izingxenye zomshini we-granite, njengezisekelo eziphezulu kanye neziqondiso ezakhiwe yi-ZHONGHUI Group (ZHHIMG®), zaziswa ngokunemba kwazo okuphezulu nokuzinzile, ukuzivikela okubonakalayo ekuguqukeni kokuqhekeka kwesikhathi eside, kanye nokumelana ngokwemvelo nokugqwala kanye nokuphazamiseka kwamagnetic. Lezi zimfanelo zenza i-granite ibe yindawo efanelekile yokubhekisela kumathuluzi ayinkimbinkimbi njenge-Coordinate Measuring Machines (CMMs) kanye nezikhungo zomshini ze-CNC ezithuthukisiwe. Naphezu kwala mandla angokwemvelo, ingabe izingxenye ze-granite azikwazi ngempela ukuwohloka, futhi yiziphi izinyathelo eziyinkimbinkimbi ezidingekayo ukuvimbela ukudaya kanye nokukhanya (ukuqhuma kwe-alkali)?
Nakuba i-granite, ngokwemvelo, ingenakugqwala, isengozini yezinselele zemvelo nezamakhemikhali. Ukungcola kanye nokukhanya—inqubo lapho usawoti oncibilikayo uthutha khona futhi ucwebezela ebusweni—kungonakalisa ubuhle nokuhlanzeka kwengxenye, okuyisici sokugcina indawo enembile kakhulu. Ukuze kulwiwe nalezi zinkinga, isu lokuvikela amakhemikhali elisebenzayo libalulekile, elilungiselelwe ngokucophelela izici ezithile ze-granite kanye nendawo yayo yokusebenza.
Ukuvikelwa Kwamakhemikhali Okulungiselelwe: Isu Elisebenzayo
Ukuvimbela ukuwohloka kuhilela ukukhetha ngokucophelela ama-sealant angena ngaphakathi. Ezingxenyeni ezisetshenziswa ezindaweni ezivame ukuchitheka kanye nokungcola okuphezulu, njengezindawo ezikhethekile zokucubungula izimboni, i-sealer yokufaka ecebile ngamakhemikhali e-fluoro asebenzayo inconywa kakhulu. Lawa ma-compounds ahlinzeka ngesithiyo esiqinile esikhulisa kakhulu ukumelana namafutha etshe kanye nokumelana namabala, sivikele ingxenye ngaphandle kokushintsha ubuqotho bayo obukhulu. Ngokuphambene nalokho, izingxenye ze-granite ezisetshenziswa ezindaweni zangaphandle noma ezinzima zezimboni zidinga ukuvikelwa ngama-sealant aqukethe ama-silicone asebenzayo. Lawa ma-formula akhethekile kumele alethe izinzuzo eziningi, kufaka phakathi ukumelana namanzi okuphezulu, ukumelana ne-UV, kanye nezakhiwo zokulwa ne-asidi, ukuqinisekisa ukuthi ukuqina kwesakhiwo kugcinwa ngokumelene nokuwohloka kwemvelo.
Ukukhetha phakathi kwezinhlobo ze-sealant kuvame ukuncika esakhiweni sangaphakathi se-granite. Ku-granite engase ibe nokwakheka okuxegayo kancane kanye nokuvuleka okuphezulu, kukhethwa i-impregnator esekelwe ku-oyela, njengoba ukungena kwayo okujulile kuqinisekisa ukondleka nokuvikelwa kwangaphakathi okuphezulu. Ku-ZHHIMG® Black Granite yethu ebanzi kakhulu, ehlangabezana nezindinganiso eziqinile zokumuncwa kwamanzi aphansi, i-sealant esekelwe emanzini esezingeni eliphezulu ngokuvamile yanele ukuvikela ubuso ngempumelelo. Ngaphezu kwalokho, lapho ukhetha izinto zokuhlanza, kubalulekile ukusebenzisa amafomula anamandla, angewona asekelwe ku-silicone. Lokhu kuvimbela ukufakwa kwezinsalela ezingangcolisa indawo yokulinganisa noma ziphazamise imisebenzi yamathuluzi elandelayo.
Ubuqotho Bobuchwepheshe Obusemuva Kokusebenza Kwe-Granite
Ukuthembeka okuqhubekayo kwezingxenye ze-ZHHIMG® kuvela ekunamatheleni ngokuqinile ezindinganisweni zobuchwepheshe. Lezi zindinganiso ziphoqelela ukusetshenziswa kwezinto ezicolekile, eziqinile njenge-gabbro, i-diabase, noma izinhlobo ezithile ze-granite ezigcina okuqukethwe kwe-biotite kungaphansi kuka-5% kanye nesilinganiso sokumuncwa kwamanzi ngaphansi kuka-0.25%. Indawo yokusebenza kumele ifinyelele ubulukhuni obudlula i-HRA 70 futhi ibe nobulukhuni obudingekayo bomphezulu (Ra). Okubaluleke kakhulu, ukunemba kokugcina kobukhulu kuqinisekiswa ngokumelene nokubekezelelana okuqinile kobuthambe kanye nobu-square.
Ukuze uthole amazinga okunemba aqine kakhulu, njengeBanga 000 kanye ne-00, umklamo ugwema ukufaka izici ezifana nezimbobo zokuphatha noma izibambo eziseceleni ukuze kuvinjelwe noma yikuphi ukucindezeleka okuncane, okungenisiwe okungaphazamisa ukunemba kokugcina. Nakuba amaphutha amancane okuhlobisa ezindaweni ezingasebenzi angase alungiswe, indawo yokusebenza kumele ihlale ihlanzekile—ingenazo nhlobo izimbobo, imifantu, noma ukungcola.
Ngokuhlanganisa ukuzinza okungokwemvelo kwe-granite esezingeni eliphezulu nalezi zidingo zobuchwepheshe eziqinile kanye nendlela eyenziwe ngokwezifiso yokulondolozwa kwamakhemikhali, onjiniyela baqinisekisa ukuthi izingxenye zomshini we-ZHHIMG® zihlala zithembekile, zinokunemba okuphezulu amathuluzi okubhekisela kuyo yonke impilo yazo yenkonzo ende kakhulu.
