ʻO kaKa uhi ʻana o CVD SiCʻO CC Composite Mould, Carbon-Carbon Composite Mould, C/C Mold from vet-china he mold hana kiʻekiʻe i hoʻolālā ʻia no nā ʻoihana e koi ana i ke kūpaʻa wela a me ke kemika. ʻO kakalapona-carbon compositehale, hoʻonui ʻia me ka uhi ʻana o ka CVD SiC (Silicon Carbide), hāʻawi i ka paʻa a me ke kūpaʻa ʻokoʻa ma lalo o nā mahana wela, e kūpono ana i nā noi noi e like me ka hana semiconductor, aerospace, a me nā ʻāpana automotive.
ʻO kaʻO ka uhi ʻana o CVD SiChāʻawi i ke kūpaʻa kupaianaha i ka ʻaʻahu a me ka oxidation, e hoʻolōʻihi i ke ola o ka mold a me ka hōʻoia ʻana i ka hana hilinaʻi i nā wahi paʻakikī. Hoʻomaikaʻi hou kēia ʻenehana hoʻopili kiʻekiʻe i ka paʻakikī o ka ʻili, pale i ka ʻōpala i nā kaʻina hana wela kiʻekiʻe a pale i ka deformation a i ʻole ka pōʻino. He kūpono loa nā mold vet-china no nā ʻoihana hoʻohanaNā apo CVD SiCa me nā ʻāpana, e hāʻawi ana i kahi hopena maikaʻi loa no ka hana kiʻekiʻe.
Ma waho aʻe o ka uhi SiC, kaʻO ka uhi CVD TaChiki ke hoʻohana ʻia no ka hoʻoikaika ʻana i ke kūpaʻa kemika, e hoʻolilo i ka mold i mea maʻalahi no nā noi like ʻole e koi ana i ka pale mai nā mea corrosive. ʻO ka ʻike loea o Vet-china ma CVD SiC a me C/C composites e hōʻoia i ka hana ʻia ʻana o kēlā me kēia mole me ka pololei, e hāʻawi ana i ka hana kiʻekiʻe ma nā ʻenehana a me nā ʻenehana.
ʻO ka hui pū ʻana o ka CVD SiC a me ka carbon-carbon composite material e hōʻoia i ka CVD SiC Coating CC Composite Mould, Carbon-Carbon Composite Mould, C/C Mold i ʻoi aku ka maikaʻi i nā kaʻina hana e pili ana i ka wela kiʻekiʻe, ka ʻike kemika, a me ke kaumaha mechanical, e hāʻawi ana i nā mea hoʻohana i kahi lōʻihi. -ʻo ka hopena mau loa a hilinaʻi.
Nā hiʻohiʻona nui:
1. Kiʻekiʻe wela oxidation kū'ē:
ʻoi aku ka maikaʻi o ka pale ʻana i ka oxidation ke kiʻekiʻe ka mahana e like me 1600 C.
2. Maʻemaʻe kiʻekiʻe: hana ʻia e ka hoʻoheheʻe ʻana i ka mahu ma lalo o ke kūlana chlorination kiʻekiʻe.
3. Erosion kū'ē: kiʻekiʻe paakiki, paʻaʻiliʻili, maikaʻi particles.
4. Ke kū'ē i ka corrosion: acid, alkali, paʻakai a me nā mea hoʻoulu.
