II-CVD SiC CoatingI-CC Composite Mould, i-Carbon-Carbon Composite Mould, i-C/C Mold evela ku-vet-china isikhunta esisebenza kahle kakhulu esiklanyelwe izimboni ezidinga ukumelana nokushisa okuphakeme namakhemikhali. Iinhlanganisela ye-carbon-carbonisakhiwo, esithuthukiswe nge-CVD SiC (Silicon Carbide) enamathelayo, sinikeza ukuqina nokuzinza okukhethekile ngaphansi kwamazinga okushisa adlulele, okuyenza ibe ilungele izinhlelo zokusebenza ezinzima ezifana nokukhiqiza i-semiconductor, i-aerospace, nemikhakha yezimoto.
II-CVD SiC coatinginikeza ukumelana okuphawulekayo kokugqoka kanye ne-oxidation, ukwandisa isikhathi sokuphila kwesikhunta kanye nokuqinisekisa ukusebenza okuthembekile ezindaweni ezinzima. Lobu buchwepheshe bokumboza obuthuthukisiwe bubuye buthuthukise ubulukhuni bobuso, buvikele isikhunta ngesikhathi sezinqubo zokushisa okuphezulu nokuvimbela ukuguquguquka noma ukulimala. Izibungu ze-vet-china zifaneleka kakhulu ezimbonini ezisetshenziswayoIzindandatho ze-CVD SiCkanye nezingxenye, ezihlinzeka ngesixazululo esilungile sokwenziwa okunembayo okuphezulu.
Ngaphezu kwe-SiC coating, i-I-CVD TaC coatingingasetshenziswa futhi ukuze kuthuthukiswe ukumelana namakhemikhali, okwenza isikhunta sisebenze ngezindlela ezihlukahlukene ezisetshenziswa ezihlukahlukene ezidinga ukuvikelwa ezintweni ezigqwalayo. Ubuchwepheshe be-Vet-china kuzinhlanganisela ze-CVD SiC kanye ne-C/C buqinisekisa ukuthi isikhunta ngasinye sakhiwe ngendlela enembile, siletha ukusebenza kwesigaba esiphezulu kuzo zombili izimo zezimboni nezobuchwepheshe.
Inhlanganisela ye-CVD SiC ne-carbon-carbon composite materials iqinisekisa ukuthi i-CVD SiC Coating CC Composite Mould, Carbon-Carbon Composite Mould, C/C Mold ihamba phambili ezinhlelweni ezibandakanya ukushisa okuphezulu, ukuchayeka kwamakhemikhali, kanye nokucindezeleka kwemishini, ihlinzeka abasebenzisi isikhathi eside. Isixazululo sesikhunta esihlala njalo, esithembekile.
Izici eziyinhloko:
1. Ukumelana nokushisa okuphezulu kwe-oxidation:
ukumelana ne-oxidation kusekuhle kakhulu lapho izinga lokushisa liphezulu njenge-1600 C.
2. Ukuhlanzeka okuphezulu: okwenziwe yi-chemical vapor deposition ngaphansi kwesimo sokushisa okuphezulu kwe-chlorination.
3. Ukumelana nokuguguleka: ubulukhuni obuphezulu, indawo ehlangene, izinhlayiya ezinhle.
4. Ukumelana nokugqwala: i-asidi, i-alkali, usawoti kanye nama-organic reagents.
