Mu dziko lopangidwa padziko lonse lapansi la kupanga zamagetsi, kuwongolera kwa mabwalo osindikizidwa (PCB) ndikofunikira. Chimodzi mwazinthu zomwe zimasokonezedwa kwambiri zomwe zimakhudza kwambiri PCB ndiye kugwiritsa ntchito granite contraction pakupanga. Wodziwika chifukwa cha kukhazikika kwake komanso kukhazikika kwake, granite amathandizanso kukhala ofunika kwambiri pakuwonetsetsa komanso kulondola pakupanga PCB.
Zigawo zikuluzikulu, monga matebulo odumphira ndi ndodo, imapereka malo okhazikika komanso osalala omwe ndi ovuta kwambiri pakusintha kwa ma PCBS. Granite matenda a granite, kuphatikiza kukana kwake ndikukula kwa markutali ndi kugwedezeka, kumathandizira kuti malo azikhala mosasinthasintha. Kukhazikika kumeneku ndikofunikira kuti mukhalebe olekerera pamagetsi amakono, monga kupatuka pang'ono kumatha kuyambitsa zovuta kapena kulephera kwa mankhwala.
Kuphatikiza apo, kugwiritsa ntchito granite mu chiwongolero chowongolera kumathandizira kulondola kwa miyezo yomwe imatengedwa pakuwunika. Magawo oyezera moyenera, akayikidwa pa granite pamwamba, kuchepetsa zolakwa zomwe zimayambitsidwa chifukwa cha zosagwirizana. Izi zimapangitsa kuti pakhale zodalirika kwambiri, kulola opanga kuti adziwe zolakwika kumayambiriro kwa nthawi yopanga momwe mungapangire panthawi yake.
Kuphatikiza apo, zigawo zikuluzikulu ndizosavuta kuyeretsa ndi kusamalira, zomwe ndizofunikira pakupanga malo opanga pomwe zodetsedwa zimatha kukhudza mtundu wa PCB. Kusakhala korona kopeka kwa granitite kumalepheretsa mayamwidwe a fumbi ndi mankhwala, kuonetsetsa kuti zinthuzo zimakhalapo komanso zothandiza kwambiri.
Pomaliza, zovuta za zigawo za gronite pamayendedwe a PCB sizingalephereke. Mwa kupereka malo okhazikika, olondola ndi oyeserera, granite amagwira ntchito yofunika kwambiri kukonza ma PCB. Monga momwe kufunikira kwa zamagetsi kumapitirira, kuyika ndalama mu njira zothetsera granite ndikofunikira kuti opanga azikhala ndi mwayi wokhala ndi mpikisano ndikuwonetsetsa kuti kudalirika kwa phindu.
