Indlela yokuvelisa intonga yokufudumeza yegrafiti kwisithando somoya

Isithando somoyaintonga yegrafayithiikwabizwa ngokuba yi-vacuum furnace graphite heating rod. Kwimihla yokuqala, abantu bajika i-graphite yaba yi-carbon, ngoko ke ibizwa ngokuba yi-intonga yekhabhoniIzinto ezisetyenziswa kwi-graphite carbon rod yi-graphite, ebizwa ngokuba yi-adhesive molding. Ingenziwa ibe ziimveliso ze-graphite ezineemilo ezahlukeneyo, kuquka ne-graphite round rod. Ngenxa yeempawu ze-graphite, ineempawu ezintle ezikhethekileyo ezifanaukuhanjiswa komoya, ukuthambisa, ukumelana nobushushu obuphezulunjalo njalo. Ke ngoko, intonga yekhabhoni yegrafiti nayo inayoukuqhuba kakuhle komoya, ukuhanjiswa kobushushu, ukuthambisa,ukumelana nobushushu obuphezulukunye nezinye iimpawu. Imeko yexesha elizayo kukuba iimpawu zegrafiti azitshintshi. Ke ngoko, ukuveliswa kunye nokunikezelwa kweentonga zegrafiti kwahlukile, kwaye iimpawu zokusebenza kweentonga zegrafiti eziveliswayo ziya kwahluka. Ngoko ke ungazahlula njani? Iimveliso zegrafiti ezenziweyo zenziwe ngokuthe ngqo ngomgubo wegrafiti kunye ne-adhesive, okanye zenziwe kuqala zibe zizinto ezinkulu zesikwere, ezicutshungulwa ngumatshini ngokwemilo yomzobo okanye yemveliso.
Kukho umahluko omkhulu kunye neempawu phakathi kwentonga ejikelezileyo yegrafiti eyenziwe yindlela yokuqala kunye nentonga ejikelezileyo yegrafiti eyenziwe yindlela yesibini. Ngenxa yoxinzelelo olunganelanga ngexesha lokukhupha,intonga yegrafayithi ekhutshiweyonge-graphite powder kunye ne-adhesive ziya kuba thambile kakhulu, zibe noxinano olubi kunye nokuqina komoya okukhulu (iimbobo ezinkulu). Uthuli luya kuwa kwimeko yendalo, kwaye luya kusasazeka xa lufakwe kwi-alcohol. Kwangaxeshanye, ngenxa yenani elikhulu le-adhesive, i-conductivity, i-heat conduction kunye ne-lubrication ye-graphite rod ziya kuncipha kakhulu, Isizathu silula kakhulu. I-Graphite sisixhobo esiqhubayo kwaye i-adhesive yi-izinto zokukhusela ubushushu, nto leyo eya kunciphisa kakhulu ukuhanjiswa kwentonga yegrafiti. Igama eliqhelekileyo lale ntonga yegrafiti yi-carbon arc air gouging carbon rod. Isetyenziselwa ukusika kwi-foundry. Umphezulu kufuneka ugqunywe ngomaleko wobhedu ukuthintela ukufuma kunye nokuhambisa umbane. Ke ngoko, olu hlobo lwentonga yekhabhoni lukwanophawu lokuba ububanzi buya kuba ngaphantsi kwe-0.1-0.2mm ephawulweyo, kuba umphezulu uya kufikelela kububanzi obuphawulweyo xa ugqunywe nge-10% yesinyithi.
Nangona indlela yesibini yenziwe ngomgubo wegrafiti kunye neglue, kukho ugxininiso olukhulu kwinkqubo yayo. Okokuqala, umgubo wegrafiti kunye neglue zisetyenziselwa ukwenza i-grafite enkuluizixhobo zegrafayithiphantsi koxinzelelo oluphezulu, uze emva kokoikhulelwengokurosa ngobushushu obuphezulu (ukufuma kunye nokuguquguquka kweglue). Ngale ndlela, akukho glue kwigrafiti emva kokurosa ngokuphindaphindiweyo. Le nkqubo yokurosa ngokufaka iglue ibaluleke kakhulu. Igrafiti encitshisiweyo emva kokurosa ngokufaka iglue ineempawu zegrafiti ngokwayo kwaye inazo zonke imisebenzi kunye neempawu zegrafiti. Ngenxa yokuba igrafiti enjalo inobunyulu obuphezulu, ikwabizwa ngokubaigrafiti ecocekileyo kakhulu, kwaye intonga yegrafiti eyenziweyo ikwabizwa ngokuba yi-grafiti rod ecocekileyo kakhulu.
