Oomatshini bokugrumba kunye noomatshini bokugaya iiPCB zizixhobo ezibalulekileyo ekwenzeni iibhodi zesekethe eziprintiweyo (iiPCB). Zisetyenziselwa ukugrumba imingxunya kunye neendlela zokugaya iiPCB, zifuna ukuchaneka okuphezulu kunye nokuchaneka ukuqinisekisa ukusebenza kweePCB. Ukuze kufezekiswe ukuchaneka okunjalo, oomatshini baxhotyiswe ngezinto ezikumgangatho ophezulu, kuquka negranite.
I-Granite lukhetho oludumileyo kwisiseko, iikholamu, kunye nezinye izinto zoomatshini bokubhola kunye nokugaya be-PCB. Yinto yendalo yelitye enokuqina okumangalisayo, uzinzo, kunye nokumelana nokuguquguquka kobushushu, okwenza ukuba ilungele ukusetyenziswa koomatshini abachanekileyo. I-Granite ikwanazo neempawu zokunciphisa ukungcangcazela ezinceda ekunciphiseni amanqanaba engxolo kunye nokunyusa ukuchaneka.
Amanqanaba okungcangcazela kunye nengxolo yezixhobo zegranite kwiimashini zokubhola kunye nezokugaya zePCB aphantsi xa kuthelekiswa nezinye izinto ezifana ne-aluminium okanye intsimbi ephosiweyo. Ukuchaneka okuphezulu kunye nokuchaneka kwezixhobo kubangelwa kakhulu kukuzinza kwazo kunye neempawu zokudambisa ukungcangcazela, eziphuculwe kakhulu kukusetyenziswa kwezixhobo zegranite. Ukuqina kunye nobunzima bezinto zegranite kunceda ukufunxa nokususa amandla okungcangcazela kwesixhobo kunye nokunciphisa amanqanaba engxolo.
Izifundo ezininzi zenziwe ukulinganisa amanqanaba okungcangcazela kunye nengxolo yezixhobo zegranite kumatshini wokubhola kunye nokugaya we-PCB. Iziphumo zibonisa ukuba oomatshini abasebenzisa izixhobo zegranite banamanqanaba okungcangcazela kunye nengxolo aphantsi, nto leyo ebangela ukuchaneka okuphezulu, ukuchaneka, kunye nomgangatho womphezulu xa kuthelekiswa nezinye iimatshini. Ezi mpawu zibaluleke kakhulu ekuvelisweni kwe-PCB, apho iimpazamo ezincinci kwimingxunya egqojoziweyo kunye neendlela ezigqojoziweyo zinokubangela ukuba ii-PCB zingasebenzi kakuhle.
Ukuqukumbela, ukusetyenziswa kwezinto zegranite kwiimashini zokubhola ze-PCB kunye nezokugaya kunika iingenelo ezininzi, kubandakanya ukuchaneka okwandisiweyo, ukuchaneka, kunye nomgangatho womphezulu. Amanqanaba okungcangcazela kunye nengxolo yoomatshini ancitshiswa kakhulu, ngokuyintloko ngenxa yeempawu zokunciphisa ukungcangcazela zegranite. Ke ngoko, abavelisi be-PCB banokufikelela kwiziphumo ezingcono kunye nesivuno esiphezulu ngezi mashini, nto leyo ebenza babe lutyalo-mali olubalulekileyo kuyo nayiphi na indawo yokuvelisa i-PCB.
