Uma kwenzeka umthwalo omkhulu noma ukusebenza ngesivinini esikhulu, ingabe izingxenye ze-granite zomshini wokubhoboza we-PCB kanye nowokugaya zizobonakala zicindezelekile ekushiseni noma zikhathele ekushiseni?

Imishini yokubhoboza neyokugaya i-PCB isetshenziswa kabanzi embonini ye-elekthronikhi. Enye yezinto ezisetshenziswa kakhulu ezingxenyeni zomshini yi-granite. I-granite iyinto eqinile futhi eqinile engamelana nemithwalo ephezulu futhi isebenze ngesivinini esikhulu.

Kodwa-ke, kuye kwaphakanyiswa ukukhathazeka mayelana nokwenzeka kokucindezeleka kokushisa noma ukukhathala kokushisa okwenzeka ezingxenyeni ze-granite zomshini wokubhoboza nokugaya we-PCB ngesikhathi somthwalo omkhulu noma ukusebenza ngesivinini esikhulu.

Ukucindezeleka kokushisa kwenzeka uma kukhona umehluko ekushiseni phakathi kwezingxenye ezahlukene zezinto. Kungabangela ukuthi izinto zande noma zinciphe, okuholela ekuguqukeni noma ekuqhekekeni. Ukukhathala kokushisa kwenzeka lapho izinto zidlula emijikelezweni ephindaphindwayo yokushisa nokupholisa, okubangela ukuba buthaka futhi ekugcineni kuhluleke.

Naphezu kwalezi zinkathazo, akunakwenzeka ukuthi izingxenye zegranite zomshini wokubhoboza nokugaya we-PCB zizobhekana nokucindezeleka kokushisa noma ukukhathala kokushisa ngesikhathi sokusebenza okuvamile. Igranite iyinto yemvelo ebilokhu isetshenziswa amakhulu eminyaka ekwakheni nasebunjiniyelani, futhi ibonakalisiwe iyinto ethembekile nehlala isikhathi eside.

Ngaphezu kwalokho, ukwakheka komshini kubheka amathuba okucindezeleka kokushisa noma ukukhathala kokushisa. Isibonelo, izingxenye zivame ukumbozwa ngesendlalelo sokuvikela ukunciphisa umthelela wokushintsha kwezinga lokushisa. Umshini futhi unezinhlelo zokupholisa ezakhelwe ngaphakathi zokulawula izinga lokushisa nokuvimbela ukushisa ngokweqile.

Ekuphetheni, ukusetshenziswa kwe-granite ezingxenyeni zemishini yokubhoboza neyokugaya i-PCB kuyindlela eqinisekisiwe nethembekile. Nakuba kuye kwaphakanyiswa ukukhathazeka mayelana nokwenzeka kokucindezeleka kokushisa noma ukukhathala kokushisa, ukwakheka komshini kuyawacabangela la maci futhi kwenza kube nzima ukuthi kwenzeke. Ukusetshenziswa kwe-granite emishinini yokubhoboza neyokugaya i-PCB kuyisinqumo esiphephile nesisebenzayo embonini ye-elekthronikhi.
