Indlela yokukhiqiza ye-graphite yokushisa induku esithandweni somlilo

Isithando somliloinduku ye-graphiteibizwa nangokuthi i-vacuum furnace graphite heat rod. Ezinsukwini zokuqala, abantu baguqule i-graphite ibe yi-carbon, ngakho ibizwa ngokuthiinduku ye-carbon. Izinto ezingavuthiwe ze-graphite carbon rod yi-graphite, ebizwa ngokuthi i-adhesive molding. Ingenziwa imikhiqizo ye-graphite yomumo ohlukahlukene, kuhlanganise ne-graphite round rod. Ngenxa yezici ze-graphite, inezici ezinhle eziyingqayizivele ezifanaconductivity, ukuthambisa, ukumelana nokushisa okuphezulunjalo njalo. Ngakho-ke, i-graphite carbon rod nayo inayoconductivity enhle kakhulu, conduction ukushisa, ukuthambisa,ukumelana nokushisa okuphezulunezinye izakhiwo. Isimo esizayo ukuthi izakhiwo ze-graphite azishintshiwe. Ngakho-ke, ukukhiqizwa nokunikezwa kwezinduku ze-graphite zihlukile, futhi izici zokusebenza zezinduku ze-graphite ezikhiqizwayo zizohluka. Ngakho kanjani ukuhlukanisa? Imikhiqizo eyenziwe ye-graphite yenziwa ngokuqondile nge-graphite powder kanye ne-adhesive, noma kuqala yenziwe ibe izinto ezinkulu zesikwele, ezicutshungulwa umshini ngokuya ngomdwebo noma ukuma komkhiqizo.
Kukhona umehluko omkhulu nezici phakathi kwe-graphite round rod eyenziwe indlela yokuqala kanye ne-graphite round rod eyenziwe indlela yesibili. Ngenxa yokucindezela okunganele ngesikhathi sokukhishwa, i-induku ye-graphite ekhishwenge-graphite powder kanye ne-adhesive izoba mnene kakhulu, ibe nokuminyana okubi kanye nokuqina okukhulu komoya (ama-pores amakhulu). Uthuli luzowela esimweni semvelo, futhi luzohlakazeka lapho lucwiliswe utshwala. Ngesikhathi esifanayo, ngenxa yenani elikhulu lokunamathela, ukuqhutshwa kokushisa, ukushisa nokugcoba kwenduku ye-graphite kuzoncishiswa kakhulu, Isizathu silula kakhulu. I-Graphite iyimpahla eqhubayo futhi ingcina iyinhlanganoi-insulating material, okubophezelekile ukunciphisa kakhulu ukuqhutshwa kwe-graphite rod. Igama elijwayelekile lale graphite carbon rod yi-carbon arc air gouging carbon rod. Isetshenziselwa ukusika endaweni etholakalayo. Indawo engaphezulu idinga ukufakwa ungqimba lwethusi ukuvimbela umswakama kanye nokuqhuba ugesi. Ngakho-ke, lolu hlobo lwe-carbon rod luphinde lube nesici sokuthi ububanzi buyoba ngaphansi kuka-0.1-0.2mm ophawulwe, ngoba ubuso buzofika nje kububanzi obumakiwe lapho buhlanganiswe nensimbi engu-10%.
Nakuba indlela yesibili nayo yenziwe nge-graphite powder kanye ne-adhesive, kugcizelelwa kakhulu inqubo yayo. Okokuqala, i-graphite powder kanye ne-adhesive isetshenziselwa ukwenza okukhuluizinto ze-graphitengaphansi kwengcindezi ephezulu, beseokhulelwengokugazinga okunezinga lokushisa eliphezulu (ukuhwamuka nokushintshashintsha kokunamathelayo). Ngale ndlela, cishe akukho okunamathelayo ku-graphite ngemva kokuwoswa kwe-imregnation okuphindaphindiwe. Le nqubo yokuthosa i-impregnation ibaluleke kakhulu. I-graphite encishisiwe ngemva kokugaya i-impregnation inezici ze-graphite ngokwayo futhi inayo yonke imisebenzi nezici ze-graphite. Ngenxa yokuthi i-graphite enjalo inokuhlanzeka okuphezulu, ibizwa nangokuthihigh-purity graphite, futhi i-graphite rod eyenziwe nayo ibizwa ngokuthi i-high-purity graphite rod.
