Iyini ukusebenza kokuvikela kwe-electromagnetic kwezingxenye ze-granite emshinini wokubhoboza nokugaya we-PCB, futhi ingabe kuyasiza ekunciphiseni ukuphazamiseka kwe-electromagnetic?

Imishini yokubhoboza i-PCB kanye nemishini yokugaya isetshenziswa kakhulu embonini yokukhiqiza ngogesi. Yenzelwe ukubhoboza nokugaya amabhodi wesekethe aphrintiwe (ama-PCB) ngokunemba okuphezulu kanye nesivinini. Kodwa-ke, le mishini ingadala ukuphazamiseka kwe-electromagnetic (EMI) ngesikhathi sokusebenza kwayo, okungathinta ukusebenza kwemishini kagesi eseduze. Ukuze kuncishiswe le nkinga, abakhiqizi abaningi bafaka izingxenye ze-granite emishinini yabo yokubhoboza nemishini yokugaya i-PCB.

I-granite iyinto eyenzeka ngokwemvelo, enobukhulu obuphezulu enezakhiwo ezinhle kakhulu zokuvikela i-electromagnetic. Ivame ukusetshenziswa ekwakhiweni kwezinhlelo zezikhulumi ezilalelwayo eziphezulu kanye nemishini ye-MRI. Izakhiwo ze-granite zenza kube yinto efanelekile ukusetshenziswa ekwakhiweni kwemishini yokubhoboza neyokugaya ye-PCB. Uma ifakwa kule mishini, izingxenye ze-granite zinganciphisa kakhulu i-EMI kanye nemiphumela yayo emishinini kagesi eseduze.

I-EMI yenzeka lapho amasimu kagesi ekhiqizwa ngamadivayisi kagesi. Lawa masimu angabangela ukuphazamiseka kwamanye amadivayisi kagesi, okuholela ekungasebenzi kahle noma ekuhlulekeni. Njengoba kukhula ubunzima bezinhlelo ze-elekthronikhi, isidingo sokuvikela i-EMI esisebenzayo siya ngokuya siba sibaluleke kakhulu. Ukusetshenziswa kwezingxenye ze-granite emishinini yokubhoboza ye-PCB kanye neyokugaya kunganikeza lesi sivikelo.

I-Granite iyisivikelo esihle kakhulu futhi ayisebenzisi ugesi. Uma i-EMI ikhiqizwa emshinini wokubhoboza nokugaya we-PCB, ingamuncwa yizingxenye ze-granite. Amandla amuncwayo abese ehlakazeka ngesimo sokushisa, kunciphisa amazinga e-EMI iyonke. Lesi sici sibalulekile enkambisweni yokukhiqiza ama-PCB ngoba amazinga aphezulu e-EMI angabangela amabhodi anephutha. Ukusetshenziswa kwezingxenye ze-granite emishinini yokubhoboza neyokugaya ye-PCB kunganciphisa ingozi yamabhodi anephutha ngenxa ye-EMI.

Ngaphezu kwalokho, i-granite iqinile ngendlela emangalisayo futhi imelana nokuguguleka. Ine-coefficient ephansi yokwanda kokushisa, okusho ukuthi ingamelana namazinga okushisa aphezulu ngaphandle kokugoba noma ukuqhekeka. Lezi zici zenza izingxenye ze-granite zibe zilungele ukusetshenziswa ezindaweni zokusebenza ezinzima zemishini yokubhoboza neyokugaya ye-PCB. Ukuqina kwezingxenye ze-granite kuqinisekisa ukuthi umshini uzosebenza kahle iminyaka, kunciphisa izindleko zokulungisa kanye nesikhathi sokungasebenzi.

Ekuphetheni, ukusetshenziswa kwezingxenye zegranite emishinini yokubhoboza neyokugaya ye-PCB kuyindlela ephumelelayo yokunciphisa amazinga e-EMI kanye nengozi yamabhodi anephutha. Izakhiwo zokuvikela zegranite zenza kube yinto efanelekile yokusetshenziswa ekwakhiweni kwale mishini. Ukuqina nokumelana nokuguguleka kwenza izingxenye zegranite zibe ukukhetha okuphelele kwezimo zokusebenza ezinzima zemishini yokubhoboza neyokugaya ye-PCB. Abakhiqizi abafaka izingxenye zegranite emishinini yabo bangaqinisekisa ukuthi amakhasimende abo athola imishini eqinile nethembekile esebenza kahle.
