Kwibhodi yesekethe eprintiweyo (PCB) yokuvelisa, ukuchaneka kunye nokuzinza kubaluleke kakhulu. Ibhedi yegranite yenye yezinto eziphambili eziphucula kakhulu ukusebenza koomatshini bokupunkisha bePCB. Ukusebenzisa igranite kwaba matshini kungaphezulu nje komkhuba; lukhetho olucwangcisiweyo olunoncedo oluninzi.
I-Granite iyaziwa ngokuqina kwayo okugqwesileyo kunye nokuxinana, okuyizona zinto zibalulekileyo ekugcineni uzinzo ngexesha lenkqubo yokubhoboza. Xa umatshini wokugqobhoza we-PCB usebenza, uxhomekeke kwimikhosi eyahlukeneyo kunye nokungcangcazela. Iibhedi zomatshini weGranite zifunxa ngokufanelekileyo ezi ntshukumo, zinciphisa intshukumo enokuthi ibangele ukuba inkqubo yokubetha ingachaneki. Olu uzinzo luqinisekisa ulungelelwaniso oluchanekileyo lwemingxuma yepunch, ebaluleke kakhulu ekusebenzeni kwemveliso yokugqibela yePCB.
Ukongezelela, ibhedi yegranite iyamelana nokwandiswa kwe-thermal. Olu phawu lubalulekile kwiindawo ezineenguqu rhoqo zobushushu. Ngokungafaniyo nezinye izinto ezinokuthi zandise okanye zivumelane nokutshintsha kweqondo lokushisa, i-granite igcina imilinganiselo yayo, iqinisekisa ukusebenza okuhambelanayo kwixesha elide. Olu uzinzo lubalulekile kwimveliso yomthamo ophezulu, njengoko nokuphambuka okuncinci kunokukhokelela kwimiba enzulu yomgangatho.
Ukongeza, ibhedi yegranite kulula ukuyigcina kwaye icoceke. Umphezulu wayo ongeyo-porous uthintela ukuqokelelwa kothuli kunye ne-debris enokuchaphazela ukusebenza komatshini. Eli nqanaba lococeko alugcini nje ukwandisa ubomi bomatshini, kodwa lunceda nokuphucula umgangatho jikelele wee-PCB eziveliswayo.
Isishwankathelo, ukudibanisa ibhedi yegranite kumatshini wokubhoboza we-PCB ngumtshintshi womdlalo. Ibhedi yeGranite yandisa ukuchaneka kunye nokusebenza kakuhle kwenkqubo yokuvelisa i-PCB ngokubonelela ngokuzinza okuphezulu, ukuchasana nokwandiswa kwe-thermal kunye nokulula ukugcinwa. Ukubaluleka kolu tshintsho alunakugqithiswa njengoko ishishini liqhubeka nokuvela, lenza igranite ibe yimathiriyeli eyimfuneko kwimveliso yale mihla yePCB.
