Hāʻawi mākou i ka hana kiʻekiʻeNā Paipu Hoʻomalu Silicon Carbide (SiC)i hana ʻia e hana pono i nā ʻano ʻoihana koʻikoʻi, me nā mahana kiʻekiʻe loa, ka pala kemika koʻikoʻi, ka ʻaʻahu mechanical a me nā haʻalulu wela pinepine. Hoʻohana nui ʻia i ka metallurgy, ka mālama wela, ka sintering ceramic, ka ʻenekinia kemika a me nā ʻoihana umu wela kiʻekiʻe, hana kā mākou mau paipu SiC ma ke ʻano he mau lima pale kaumaha no nā thermocouples, nā nozzles burner, nā ʻāpana hoʻoili wela a me nā uhi umu, e hoʻolōʻihi pono ana i ke ola lawelawe lako a me ka hōʻemi ʻana i nā kumukūʻai mālama maʻamau.
Hāʻawi mākou i ʻekolu mau papa premium nui e hoʻokō i nā pono noi like ʻole:ʻO ka SiC i hoʻopaʻa ʻia me ka hopena (RBSiC), ʻo ka SiC i hoʻopili hou ʻia (RSiC) a me ka SiC i hoʻopaʻa ʻia me ka Silicon Nitride (NBSiC).Loaʻa i kēlā me kēia papa nā pono hana kūikawā, a hāʻawi mākou i nā lawelawe hana maʻamau piha e hoʻokō i kāu nui kikoʻī, ka hoʻonohonoho a me nā koi kūlana hana.
1. Hana Hana Maʻamau | Loaʻa ʻo OEM & ODM
Hoʻomaopopo piha mākou he mau koi kūikawā ko nā mea kūʻai aku ʻoihana no ka nui, ke ʻano, ke kau ʻana a me ka hana. Hāʻawi mākou i nā hoʻonā maʻamau piha no nā paipu pale SiC, e uhi ana i ka hoʻolālā huahana, ka hoʻomohala prototype, ka hana nui a me ka nānā pono ʻana i ka maikaʻi. E paipai kā mākou hui loea i ka papa SiC kūpono loa e pili ana i kāu mahana hana, ke ʻano waena, ke kaomi a me ka wahi hoʻonohonoho e hōʻoia i ka hana kūpono a me ka pono o ke kumukūʻai no kāu papahana.
2. Pae Hoʻopilikino
(1) Hoʻopilikino Ana:ʻO ke anawaena waho mai Φ12mm a i Φ300mm, ka lōʻihi hoʻokahi a i 3000mm, hiki ke hoʻopilikino ʻia ka mānoanoa o ka paia mai 3mm a 30mm, me nā ʻae ʻana o ka dimensional paʻa (± 0.5mm a i ± 1.0mm) e pili ana i nā kikoʻī huahana a me nā koi kaʻina hana e hōʻoia i ka kūpono kūpono me nā lako o ka mea kūʻai aku.
(2) Hoʻonohonoho ʻana i ka hoʻonohonoho ʻana a me ka hopena:Kākoʻo i ka hopena pani, ka hopena hāmama, ka hopena flanged (nā flanges maʻamau a me nā flanges maʻamau ʻole), nā pilina wili kūloko a me waho, nā ʻauwaha apo sila, nā lua hoʻonoho, a me nā hoʻolālā kūkulu ʻē aʻe. Hāʻawi pū mākou i nā huahana ʻano kūikawā maʻamau, me nā paipu kūlou 45°/90°, nā paipu hoʻēmi, nā tee, a me nā ʻano finned no nā pono hoʻonohonoho a me ka noi kikoʻī.
(3) Hoʻopilikino Hana:Hoʻoponopono i ka porosity o ka mea, ka conductivity thermal, ka ikaika compressive, a me nā palena kūpaʻa i ka corrosion e like me nā kūlana hana kūikawā, hoʻomaikaʻi i ka hoʻohuihui mea e hoʻokūkū i nā wahi ʻino kū hoʻokahi, a hoʻomaikaʻi i ke ola lawelawe i kuhikuhi ʻia a me ke kūpaʻa o ka hana.
(4) Hoʻopilikino Hana:Ka hoʻololi maʻalahi ma waena o nā kaʻina hana RBSiC, RSiC, a me NBSiC e pili ana i nā hiʻohiʻona noi o ka mea kūʻai aku; no nā ʻāpana kūkulu paʻakikī, hoʻokau mua mākou i ke kaʻina hana sintering hopena kokoke i ka ʻupena e hōʻemi i nā kumukūʻai hana a hōʻoia i ka kūpaʻa o ke kūkulu ʻana.
Nā Paipu Hoʻomalu SiC i Hoʻopaʻa ʻia me Silicon Nitride (NBSiC)
Hana ʻia nā paipu NBSiC mai ka SiC maʻemaʻe kiʻekiʻe a me ka pauka silicon, i hana ʻia e ka extrusion a i ʻole grouting, a laila nitrided ma 1350-1500°C i ka lewa naikokene. Hoʻopaʻa pono nā kristal silicon nitride acicular i nā ʻāpana SiC, e hana ana i kahi hui paʻa me ke kūpaʻa ʻokoʻa o ka metala hoʻoheheʻe a me ka hana ʻaʻole e pipili, kūpono no nā hiʻohiʻona hoʻoheheʻe metala non-ferrous.
1. Hana Koʻikoʻi a me nā Hiʻohiʻona
(1) ʻO ka mahana hana kiʻekiʻe loa a hiki i ka 1500°C, me ka hana paʻa i nā metala hoʻoheheʻe ʻia a me nā wahi ʻinoʻino wela kiʻekiʻe
(2) Ke kūpaʻa maikaʻi loa i ka alumini hoʻoheheʻe ʻia, ka zinc, ke keleawe, a me nā metala hao ʻē aʻe ʻaʻole ferrous, me ka ʻole o ka hoʻopili ʻana i nā metala hoʻoheheʻe ʻia a ʻaʻohe haumia wai metala
(3) Ke alakaʻi wela kiʻekiʻe, e hiki ai ke ʻike wikiwiki i ka mahana a me ka hoʻoili wela kūpono no ka nānā pono ʻana i ka mahana
(4) Ikaika maikaʻi o ka mīkini a me ke kūpaʻa ʻana i ka haʻalulu wela, kūpono no ka lawelawe lōʻihi i nā hiʻohiʻona hoʻoheheʻe metallurgical a me ka hoʻolei ʻana
(5) Haʻahaʻa ka porosity a me ke ʻano paʻa, e hoʻokaʻawale pono ana i ka metala hoʻoheheʻe ʻia, slag, a me nā kinoea corrosive e pale i nā ʻāpana kūloko
2. Nā Noi i Manaʻo ʻia
Ua hoʻolālā kūikawā ʻia nā paipu pale NBSiC no nā ʻoihana hao hao, hoʻohana nui ʻia no nā paipu ana wela metala hoʻoheheʻe ʻia, nā paipu hāpai, nā lima pale thermocouple umu hoʻoheheʻe alumini/keleawe/zinc, nā ʻāpana pale loko hoʻoheheʻe ʻia, a me nā lako hana hoʻolei mau. ʻO lākou ka hopena premium no ke kūpaʻa ʻana i ka pala metala hoʻoheheʻe ʻia a me nā koi hana ʻaʻole e pipili.
Nā Paipu Hoʻomalu SiC i Hoʻopaʻa ʻia me ka Reaction (RBSiC)
Hana ʻia nā paipu RBSiC ma o ka ʻenehana infiltration a me ka reaction sintering holomua, me ka hoʻohana ʻana i ka pauka SiC maʻemaʻe kiʻekiʻe a me nā mea maka kalapona. Hoʻokomo ka silicon hoʻoheheʻe i loko o ke kino ʻōmaʻomaʻo a pane i loko e hana i kahi ʻano paʻa paʻa, me ka 8-15% o ka silicon manuahi. Hiki i kēia kaʻina hana ke hana i ke ʻano kokoke i ka ʻupena me ka emi ma mua o 1% dimensional shrinkage, e hāʻawi ana i ka pono kumukūʻai kiʻekiʻe a kūpono hoʻi no ka hana ʻoihana nui.
1. Hana Koʻikoʻi a me nā Hiʻohiʻona
(1) ʻO ka mahana hana kiʻekiʻe loa a hiki i ka 1400°C, me ka hana lawelawe lōʻihi paʻa ma nā mahana kiʻekiʻe mau
(2) Kiʻekiʻe ke kiʻekiʻe o ka nui, ikaika mechanical maikaʻi loa, a me ke kūpaʻa maikaʻi i ka hopena mechanical a me ka ʻaʻahu abrasive palupalu
(3) ʻOi aku ka maikaʻi o ke kumukūʻai i hoʻohālikelike ʻia me nā ʻano SiC ʻē aʻe, kūpono no nā noi ʻoihana nui
(4) ʻOi aku ka maikaʻi o ke ʻano, e hiki ai ke hana i nā ʻāpana ʻano paʻakikī me ka ʻole o ka hana lua nui
(5) Kū'ē maikaʻi i ka palaho kemika maʻamau, me nā lewa ʻoihana waikawa a me ka alkaline
2. Nā Noi i Manaʻo ʻia
Hoʻohana nui ʻia nā paipu pale RBSiC no nā paipu radiation umu metallurgical, nā ʻūlū pale thermocouple maʻamau, nā nozzles desulfurization, nā mea hoʻololi wela, a me nā ʻāpana umu wela kiʻekiʻe. ʻO lākou ke koho kūpono loa no nā noi e pono ai ka hana kaulike a me ka kaohi kumukūʻai, me ka ʻole o ke koi no ke kūpaʻa wela kiʻekiʻe loa ma luna o 1400°C.
Nā Paipu Hoʻomalu SiC (RSiC) i Hoʻopili Hou ʻia
Hoʻopaʻa ʻia nā paipu RSiC ma ka mahana kiʻekiʻe loa (2100-2450°C) me ka ʻole o kekahi pae hoʻopaʻa lua, i hana ʻia e ka mahu pololei a me ka condensation o nā ʻāpana α-SiC maʻemaʻe kiʻekiʻe. Hōʻoia kēia ʻano crystalline maʻemaʻe i ka haumia ʻole, e lilo ia i koho kiʻekiʻe no nā wahi hana mahana kiʻekiʻe loa a me ka maʻemaʻe kiʻekiʻe.
1. Hana Koʻikoʻi a me nā Hiʻohiʻona
(1) Ke kūpaʻa wela kiʻekiʻe loa, me ka mahana hana mau loa a hiki i ka 1800°C, kūpono no nā kūlana hana wela kiʻekiʻe loa
(2) 100% pae kristal SiC maʻemaʻe, ʻaʻohe haumia haumia, kūpono no ka mālama wela kiʻekiʻe a me nā umu i kāohi ʻia e ka lewa
(3) Ke kūpaʻa haʻalulu wela kūikawā, hiki ke kū i nā loli wela wikiwiki me ka ʻole o ka haki a i ʻole ka hōʻino ʻia
(4) Ke alakaʻi wela kiʻekiʻe a me ke kūpaʻa wela kiʻekiʻe maikaʻi loa, e mālama ana i ka pono o ke kūkulu ʻana ma lalo o ka hōʻike wela kiʻekiʻe loa no ka manawa lōʻihi
(5) Ke kūpaʻa ikaika i ka ʻino kinoea a me ka ʻaʻahu abrasive, kūpono no nā wahi umu ʻino me nā kahe kiʻekiʻe a me ka hopena o nā ʻāpana
2. Nā Noi i Manaʻo ʻia
Hoʻohana nui ʻia nā paipu pale RSiC i nā umu wela kiʻekiʻe, nā umu lewa, nā umu mālama wela ʻoihana, nā nozzles kuni wela kiʻekiʻe, nā lako puhi keramika maʻemaʻe kiʻekiʻe, a me nā ʻāpana hana wela kiʻekiʻe kūikawā. ʻAʻole hiki ke hoʻololi ʻia no nā hiʻohiʻona e pono ai ke kūpaʻa wela kiʻekiʻe loa, ka maʻemaʻe kiʻekiʻe, a me ke kūpaʻa wela koʻikoʻi.
