Hāʻawi kā mākou hui i nā lawelawe kaʻina hana hoʻoheheʻe SiC ma ke ʻano CVD ma ka ʻili o ka graphite, ceramics a me nā mea ʻē aʻe, i hiki ai i nā kinoea kūikawā i loaʻa ke kalapona a me ke silika i ke kiʻekiʻe kiʻekiʻe e loaʻa ai nā molekala SiC maʻemaʻe kiʻekiʻe. e hana ana i ka papa pale SIC.
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.

Nīnau: He hui kālepa a mea hana paha ʻoe?
A: He ʻoi aku mākou ma mua o 10 mau makahiki me ka ISO9001 i hōʻoia ʻia.
Q: Pehea ka lōʻihi o kāu manawa hoʻouna?
A: ʻO ka maʻamau he 3-5 mau lā inā loaʻa nā waiwai, a i ʻole 10-15 mau lā inā ʻaʻole i loko o nā waiwai, e like me kāu nui.
Q: Pehea e hiki ai iaʻu ke kiʻi i ka laʻana e nānā i kou maikaʻi?
A: Ma hope o ka hōʻoia ʻana o ke kumukūʻai, hiki iā ʻoe ke koi i nā laʻana e nānā i ka maikaʻi o kā mākou huahana. Inā makemake ʻoe i kahi laʻana hakahaka e nānā i ka hoʻolālā a me ka maikaʻi, e hāʻawi mākou iā ʻoe i kahi laʻana no ka manuahi ʻoiai ʻoe e hāʻawi i ka ukana hōʻike.
Q: He aha kāu mau ʻōlelo uku?
A: Keʻae nei mākou i ka uku e ka Western Union, Paypal, Alibaba, T / T, L / C, a me nā mea'ē aʻe.
Inā he nīnau ʻē aʻe kāu, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou ma lalo nei:
