Ukusetshenziswa kwe-granite emishinini yokubhoboza neyokugaya i-PCB sekuthandwa kakhulu ngenxa yokuqina kwayo okuphezulu, ukumelana nokuguguleka okuphezulu, kanye nekhono lokunciphisa ukudlidliza. Kodwa-ke, abakhiqizi abaningi be-PCB baphakamise ukukhathazeka ngokusebenza kwezakhi ze-granite ezindaweni ezibucayi njengokushisa okuphezulu, izinga lokushisa eliphansi, kanye nomswakama ophezulu.
Ngenhlanhla, ukusebenza kwezakhi ze-granite emishinini yokubhoboza neyokugaya ye-PCB kuzinzile kakhulu ngisho nasezindaweni ezimbi kakhulu. Okokuqala nokubaluleke kakhulu, i-granite imelana kakhulu nokushintsha kwezinga lokushisa nokushintshashintsha. Lokhu kungenxa yokuthi i-granite uhlobo lwetshe lemvelo elakhiwa ukupholisa nokuqina kwe-magma encibilikisiwe. Ngenxa yalokho, ingadlula ezindaweni ezishisa kakhulu ngaphandle kokulahlekelwa ukuqina noma ukuma kwayo.
Ngaphezu kwalokho, i-granite ayithambekele ekukhuleni noma ekuncipheni ngenxa yezinguquko ekushiseni noma ekumswakama. Lokhu kuntuleka kokwanda nokuncipha kuqinisekisa ukuthi izakhi ze-granite emishinini yokubhoboza neyokugaya ye-PCB zihlala zizinzile ngesikhathi sokusebenza, nokuthi umshini ukhiqiza imiphumela eqondile nekhwalithi ephezulu.
Ngaphezu kwalokho, i-granite imelana kakhulu nokugqwala, okuyinzuzo eyengeziwe uma kuziwa ekugcineni ukusebenza kwemishini yokubhoboza neyokugaya ye-PCB ezindaweni ezinomswakama ophezulu. Ukumelana kwe-granite kutholakala kokuqukethwe kwayo kwe-silica, okwenza itshe limelane nama-acid nama-alkali, ngaleyo ndlela kuqinisekiswe ukuthi aligqwali kalula.
Enye inzuzo yokusebenzisa i-granite emishinini yokubhoboza i-PCB kanye neyokugaya yikhono layo lokudambisa ukudlidliza. Lokhu kusiza ukuqinisekisa ukuthi umshini uzinzile ngesikhathi sokusebenza nokuthi i-drill bit noma i-milling cutter ayimbi kakhulu ebhodini.
Sekukonke, ukusetshenziswa kwezinto ze-granite emishinini yokubhoboza neyokugaya ye-PCB kunconywa kakhulu. Ngenxa yokuqina kwayo okuphezulu, ukumelana nokuguguleka okuphezulu, kanye nekhono lokunciphisa ukudlidliza, i-granite iyinto ephelele yokuqinisekisa ukunemba nokunemba okudingekayo ngesikhathi senqubo yokukhiqiza amabhodi wesekethe aphrintiwe.
Ekuphetheni, abakhiqizi be-PCB akudingeki bakhathazeke ngokusebenza kwezakhi ze-granite ezindaweni ezibucayi kakhulu. Amandla e-granite okumelana nokushintsha kwezinga lokushisa, umswakama, kanye nokugqwala ayenza iqine futhi ithembeke kakhulu. Ngenxa yalokho, ukusetshenziswa kwe-granite emishinini yokubhoboza neyokugaya ye-PCB kunconywa kakhulu, futhi abakhiqizi bangaphumula bazi ukuthi ukusebenza kwemishini yabo kuzohlala kuzinzile futhi kuthembekile.
