Mu ntchito zamafakitale, granite imakondedwa kwambiri chifukwa cha kuuma kwake, kulimba kwake, kukongola kwake ndi zina. Komabe, pali zochitika zina pamsika pomwe zinthu zolowa m'malo mwa marble zimaonedwa ngati granite. Munthu amatha kusankha granite yapamwamba kwambiri pokhapokha akadziwa bwino njira zodziwira. Njira zodziwira ndi izi:
1. Yang'anani mawonekedwe ake
Kapangidwe ndi kapangidwe: Kapangidwe ka granite nthawi zambiri kamakhala kofanana komanso kosalala, kopangidwa ndi tinthu ta mchere monga quartz, feldspar, ndi mica, komwe kumakhala ndi nyenyezi zowala za mica ndi makhiristo a quartz owala, okhala ndi kufalikira kofanana. Kapangidwe ka marble nthawi zambiri kamakhala kosasinthasintha, makamaka mu mawonekedwe a flakes, mizere kapena mikwingwirima, yofanana ndi mapangidwe a chithunzi chojambulidwa. Ngati muwona kapangidwe ka mizere yowonekera bwino kapena mapangidwe akuluakulu, mwina si granite. Kuphatikiza apo, tinthu ta mchere ta granite yapamwamba kwambiri tikakhala tating'ono kwambiri, timakhala bwino, kusonyeza kapangidwe kolimba komanso kolimba.
Mtundu: Mtundu wa granite umadalira makamaka kapangidwe kake ka mchere. Kachulukidwe ka quartz ndi feldspar kakachuluka, mtundu wake umakhala wopepuka, monga mndandanda wamba wa imvi-yoyera. Pamene kuchuluka kwa mchere wina kuli kochuluka, ma granite amtundu wa imvi-yoyera kapena imvi amapangidwa. Omwe ali ndi potaziyamu wambiri wa feldspar amatha kuwoneka ofiira. Mtundu wa marble umagwirizana ndi mchere womwe uli nawo. Umaoneka wobiriwira kapena wabuluu ukakhala ndi mkuwa, ndi wofiira pang'ono ukakhala ndi cobalt, ndi zina zotero. Mitundu yake imakhala yolemera komanso yosiyanasiyana. Ngati mtunduwo ndi wowala kwambiri komanso wosazolowereka, ukhoza kukhala njira yonyenga yosinthira utoto.
II. Yesani makhalidwe enieni
Kulimba: Granite ndi mwala wolimba wokhala ndi kulimba kwa Mohs kwa 6 mpaka 7. Pamwamba pake pakhoza kukanda pang'onopang'ono ndi msomali wachitsulo kapena kiyi. Granite yapamwamba kwambiri sidzasiya zizindikiro zilizonse, pomwe marble ali ndi kulimba kwa Mohs kwa 3 mpaka 5 ndipo nthawi zambiri amakanda. Ngati n'zosavuta kukhala ndi mikwingwirima, mwina si granite.
Kuyamwa madzi: Kuponya dontho la madzi kumbuyo kwa mwalawo ndikuwona kuchuluka kwa kuyamwa. Granite ili ndi kapangidwe kolimba komanso kuyamwa madzi kochepa. Madzi si osavuta kulowa ndipo amafalikira pang'onopang'ono pamwamba pake. Marble ili ndi mphamvu yayikulu yoyamwa madzi, ndipo madzi amalowa kapena kufalikira mwachangu. Ngati madontho a madzi atha kapena kufalikira mwachangu, sangakhale granite.
Phokoso la kugogoda: Gokoda mwalawo pang'onopang'ono ndi nyundo yaying'ono kapena chida chofanana nacho. Granite yapamwamba kwambiri ili ndi kapangidwe kolimba ndipo imapanga phokoso lomveka bwino komanso losangalatsa ikagundidwa. Ngati pali ming'alu mkati kapena kapangidwe kake katasunthika, phokoso lidzakhala losamveka bwino. Phokoso la marble lomwe likugundidwa silikhala lolimba kwenikweni.
Iii. Yang'anani khalidwe la kukonza
Ubwino wa kupukutira ndi kupukuta: Gwirani mwalawo kuti usagwere padzuwa kapena nyali ya fluorescent ndipo yang'anani pamwamba pake. Pambuyo poti pamwamba pa granite yapamwamba kwambiri yaphwanyidwa ndi kupukutidwa, ngakhale kuti kapangidwe kake kakang'ono ndi kosalala komanso kosagwirizana kakakulitsidwa ndi maikulosikopu yamphamvu kwambiri, kayenera kukhala kowala ngati galasi m'maso, ndi mabowo ndi mizere yosalala komanso yosakhazikika. Ngati pali mizere yowonekera bwino komanso yokhazikika, zimasonyeza kuti ntchito yake ndi yoipa ndipo ikhoza kukhala chinthu chabodza kapena chosakhazikika.
Kaya muphike sera: Amalonda ena osakhulupirika amapaka sera pamwamba pa mwalawo kuti aphimbe zolakwika zomwe zachitika. Gwirani pamwamba pa mwalawo ndi dzanja lanu. Ngati ukumva mafuta, mwina wapakidwa sera. Muthanso kugwiritsa ntchito machesi owala kuti muphike pamwamba pa mwalawo. Mafuta pamwamba pa mwalawo wopakidwa sera adzaonekera bwino.
Zinayi. Samalani ndi zina
Chongani satifiketi ndi komwe kwachokera: Funsani wogulitsa kuti akupatseni satifiketi yowunikira ubwino wa mwalawo ndipo onani ngati pali deta iliyonse yoyesera monga zizindikiro za radioactive. Podziwa komwe mwalawo wachokera, ubwino wa granite wopangidwa ndi migodi yayikulu wamba ndi wokhazikika.
Kuweruza mitengo: Ngati mtengo uli wotsika kwambiri kuposa momwe msika umakhalira, samalani kuti ndi chinthu chabodza kapena chosalongosoka. Kupatula apo, mtengo wofukula ndi kukonza granite wapamwamba ulipo, ndipo mtengo wotsika kwambiri siwokwera mtengo kwenikweni.
