Ukusetyenziswa kwegranite kwiimashini zokubhola kunye nezokugaya ze-PCB kuye kwathandwa kakhulu ngenxa yozinzo lwayo oluphezulu, ukumelana nokuguguleka okuphezulu, kunye nokukwazi kwayo ukunciphisa ukungcangcazela. Nangona kunjalo, abavelisi abaninzi be-PCB baphakamise inkxalabo malunga nokusebenza kwezinto zegranite kwiindawo ezishushu kakhulu ezifana nobushushu obuphezulu, ubushushu obuphantsi, kunye nokufuma okuphezulu.
Ngethamsanqa, ukusebenza kwezinto zegranite kwiimashini zokubhola kunye nezokugaya zePCB kuzinzile kakhulu nakwiindawo ezishushu kakhulu. Okokuqala nokubalulekileyo, igranite iyamelana kakhulu notshintsho lobushushu kunye nokuguquguquka. Oku kungenxa yokuba igranite luhlobo lwelitye lendalo elenziwa kukupholisa kunye nokuqina kwe-magma enyibilikisiweyo. Ngenxa yoko, inokudlula kwiindawo ezishushu kakhulu ngaphandle kokulahlekelwa bubungqongqo okanye imo yayo.
Ngaphezu koko, i-granite ayityekeli ekukhuleni okanye ekuncipheni ngenxa yotshintsho kubushushu okanye kumswakama. Oku kungabikho kokwanda nokuncipha kuqinisekisa ukuba izinto ze-granite kwiimashini zokubhola kunye nezokugaya ze-PCB zihlala zizinzile ngexesha lokusebenza, kwaye umatshini uvelisa iziphumo ezichanekileyo nezisemgangathweni.
Ukongeza, i-granite iyakwazi ukumelana nokugqwala, nto leyo eyinzuzo eyongezelelweyo xa kufikwa ekugcineni ukusebenza kakuhle koomatshini bokugqwala kunye nokugaya be-PCB kwiindawo ezinomswakama ophezulu. Ukumelana kwe-granite kuvela kumxholo wayo we-silica, okwenza ilitye likwazi ukumelana nee-asidi kunye ne-alkalis, ngaloo ndlela kuqinisekiswa ukuba aligqwali lula.
Enye inzuzo yokusebenzisa igranite kumatshini wokubhola we-PCB kunye noomatshini bokugaya kukukwazi kwayo ukuthomalalisa ukungcangcazela. Oku kunceda ukuqinisekisa ukuba umatshini uzinzile ngexesha lokusebenza kwaye i-drill bit okanye i-milling cutter ayigrumbi nzulu kakhulu ebhodini.
Lilonke, ukusetyenziswa kwezinto zegranite kumatshini wokubhola we-PCB kunye nowokugaya kuyacetyiswa kakhulu. Ngenxa yokuzinza kwayo okuphezulu, ukumelana nokuguguleka okuphezulu, kunye nokukwazi kwayo ukuthomalalisa ukungcangcazela, igranite yeyona nto ifanelekileyo yokuqinisekisa ukuchaneka kunye nokuchaneka okufunekayo ngexesha lenkqubo yokwenziwa kweebhodi zesekethe eziprintiweyo.
Ukuqukumbela, abavelisi be-PCB akufuneki bakhathazeke ngokusebenza kwezinto ze-granite kwiindawo ezixineneyo. Amandla e-granite okumelana notshintsho lobushushu, ukufuma, kunye nokugqwala ayenza ihlale izinzile kwaye ithembeke kakhulu. Ngenxa yoko, ukusetyenziswa kwe-granite kumatshini wokubhola kunye nokugaya i-PCB kuyacetyiswa kakhulu, kwaye abavelisi banokuphumla besazi ukuba ukusebenza koomatshini babo kuya kuhlala kuzinzile kwaye kuthembekile.
