Izinto ze-granite sezithandwa kakhulu ekwakhiweni nasekwakheni imishini yokubhoboza nokugaya i-PCB. Lokhu kungenxa yekhono lazo lokubekezelela amazinga okushisa aphezulu akhiqizwa ngesikhathi senqubo yokugaya ngaphandle kokulahlekelwa ubuqotho bazo besakhiwo. Ukusetshenziswa kwezinto ze-granite emishinini yokubhoboza neyokugaya i-PCB kuthuthukisa ukunemba, ukunemba kanye nesivinini senqubo okuholela emikhiqizweni yokugcina esezingeni eliphezulu.
Ububanzi bokuhlukahluka kwezinga lokushisa kwezinto ze-granite ezisetshenziswa emishinini yokubhoboza neyokugaya ye-PCB buncike ezintweni eziningana. Lezi zici zifaka phakathi uhlobo lwe-granite olusetshenziswayo, ubukhulu be-granite element, isivinini sokubhoboza noma sokugaya, kanye nokujula nosayizi womgodi oshintshwayo.
Ngokuvamile, i-granite inomthamo ophansi wokukhula kokushisa, okusho ukuthi izomelana nokuguquguquka kanye nomonakalo obangelwa amazinga okushisa aphezulu. Ngaphezu kwalokho, i-granite inamandla aphezulu okushisa, okuyivumela ukuthi imunce ukushisa futhi igcine izinga lokushisa elihambisanayo. Lokhu kuyenza ibe yinto efanelekile yokusetshenziswa emishinini yokubhoboza neyokugaya i-PCB, lapho amazinga okushisa aphezulu ekhiqizwa khona ngesikhathi senqubo yokugaya.
Izinto eziningi zegranite ezisetshenziswa emishinini yokubhoboza neyokugaya i-PCB zinezinga lokushintshashintsha kwezinga lokushisa eliphakathi kuka-20℃ no-80℃. Kodwa-ke, lolu hlu lungahluka kuye ngohlobo lwegranite esetshenziswayo. Isibonelo, igranite emnyama, enamandla okushisa aphezulu, ingamelana namazinga okushisa aphezulu uma kuqhathaniswa nezithunzi zegranite ezilula.
Ngaphezu kobubanzi bokuhlukahluka kwezinga lokushisa, ukujiya kwento ye-granite nakho kuyisici esibalulekile okufanele sicatshangelwe. Izinto ze-granite ezijiyile zikwazi kangcono ukumunca ukushisa futhi zigcine izinga lokushisa elizinzile ngesikhathi senqubo yokugaya. Lokhu kuqinisekisa ukuthi ukunemba nokunemba komshini wokubhoboza nokugaya we-PCB kuyagcinwa ngisho nangemva kokusetshenziswa isikhathi eside.
Ijubane lokubhoboza noma lokugaya nalo liyisici esibalulekile okufanele sicatshangelwe lapho kusetshenziswa izakhi ze-granite emishinini yokubhoboza ye-PCB kanye neyokugaya. Ijubane eliphezulu lokubhoboza noma lokugaya lidala ukushisa okwengeziwe, okungabangela umonakalo ku-granite element. Ngakho-ke, kubalulekile ukulawula ijubane lomshini ukuqinisekisa ukuthi izinga lokushisa eliguquguqukayo le-granite element liyagcinwa.
Ekuphetheni, ukusetshenziswa kwezinto ze-granite kushintshe inqubo yokubhoboza nokugaya i-PCB. Zihlala isikhathi eside futhi ziyakwazi ukumelana namazinga okushisa aphezulu ngaphandle kokulimala. Ububanzi bokuhlukahluka kwezinga lokushisa kwezinto ze-granite ezisetshenziswa emishinini yokubhoboza neyokugaya i-PCB buphakathi kuka-20℃ no-80℃, kuye ngokuthi ubukhulu kanye nohlobo lwe-granite esetshenziswayo buyini. Ngalolu lwazi, onjiniyela kanye nochwepheshe bangakhetha into efanele ye-granite yemishini yabo yokubhoboza neyokugaya i-PCB ukuze bathuthukise ukusebenza futhi bafinyelele imikhiqizo yokugcina esezingeni eliphezulu.
