Yiziphi izinhlobo ezahlukene ze-graphite crucibles?
ngo-admin ku-25-02-19
I-graphite crucibles ingahlukaniswa ngezinhlobo eziningi ngokuya ngezinto ezihlukene, izakhiwo kanye nokusetshenziswa. Okulandelayo yizinhlobo ezimbalwa ezivamile ze-graphite crucibles nezici zazo: 1. I-Clay Graphite Crucible Material Ukwakheka: Yenziwe ngengxube ye-graphite yemvelo kanye ne-refractory...

Izinkambu zokusetshenziswa zezinto ezihlanganisiwe ze-carbon/carbon
ngo-admin ku-24-12-31
Kusukela yasungulwa ngeminyaka yawo-1960s, izinhlanganisela ze-carbon-carbon C/C zithole ukunakwa okukhulu kwamasosha, i-aerospace, kanye nezimboni zamandla enuzi. Ekuqaleni, inqubo yokwenziwa kwenhlanganisela ye-carbon-carbon yayiyinkimbinkimbi, inzima ngokobuchwepheshe, futhi inqubo yokulungiselela yayi...

Indlela yokuhlanza isikebhe se-PECVD graphite?| Amandla we-VET
ngo-admin ku-24-12-23
1. Ukuvuma ngaphambi kokuhlanza i-1) Uma isikebhe / umthwali we-graphite we-PECVD sisetshenziswa izikhathi ezingaphezu kwe-100 kuya kwezingu-150, opharetha udinga ukuhlola isimo sokumboza ngesikhathi. Uma kukhona ukunamathela okungavamile, kudinga ukuhlanzwa nokuqinisekiswa. Umbala wokwemboza ojwayelekile we-th...
