ʻO ka Magnesium diboride kahi hui ionic, me ke ʻano aniani hexagonal.E hoʻololi ʻia ka Magnesium diboride ma kahi mahana wela iki 40K (e like me -233 ℃) i superconductor.A ʻo kona mahana hana maoli ʻo 20 ~ 30K.No ka hiki ʻana i kēia mahana, hiki iā mākou ke hoʻohana i ka neon wai, ka hydrogen wai a i ʻole ka pahu pahu pahu pani e hoʻopau ai i ka hoʻoilo.Ke hoʻohālikelike ʻia i ka ʻoihana o kēia manawa e hoʻohana ana i ka helium wai e hoʻomaha ai i ka alloy niobium (4K), ʻoi aku ka maʻalahi o kēia mau ʻano hana.I ka manawa e hoʻopaʻa ʻia me ke kalapona a i ʻole nā ​​​​mea haumia ʻē aʻe, magnesium diboride i loko o kahi māla magnetic, a i ʻole he hala i kēia manawa, ʻo ka hiki ke mālama i ka superconducting e like me nā alloys niobium, a ʻoi aku ka maikaʻi.

ʻO kā mākou pono

ʻO ka lawelawe hiki iā mākou ke hāʻawi
1) Hiki ke hoʻopaʻa inoa ʻia ka ʻaelike maʻamau

2) Hiki ke pūlima ʻia ka ʻaelike hūnā
3) ʻEhiku lā hoʻihoʻi hōʻoia
ʻOi aku ka mea nui: hiki iā mākou ke hāʻawi i ka huahana wale nō, akā ʻo ka lawelawe ʻenehana hoʻonā!
Hoʻopaʻa a hoʻouna

No ka hōʻoia maikaʻi ʻana i ka palekana o kāu mau waiwai, e hāʻawi ʻia nā lawelawe ʻoihana ʻoihana, pili kaiapuni, kūpono a maikaʻi hoʻi.

Hoʻolauna Hui

Aia ʻo Shanghai Epoch Material Co., Ltd. ma ke kikowaena waiwai—Shanghai.Hoʻopili mau mākou i "Nā mea ʻoi aku ka maikaʻi, ola maikaʻi" a me ke komite i ka ʻimi noiʻi a me ka hoʻomohala ʻana o ka ʻenehana, e hoʻohana ai i ke ola o ke kanaka i kēlā me kēia lā e hoʻomaikaʻi i ko mākou ola.

I kēia manawa, pili nui mākou i nā mea ʻenehana honua, nā mea nano, nā mea OLED, a me nā mea holomua ʻē aʻe.Hoʻohana nui ʻia kēia mau mea kiʻekiʻe i ka kemika, lāʻau lapaʻau, biology, hōʻike OLED, kukui OLED, ka mālama ʻana i ke kaiapuni, ka ikehu hou, etc.

No kēia manawa, loaʻa iā mākou ʻelua hale hana ma Shandong Province.Uhi ia i kahi o 30,000 square meters, a he poʻe hana ma mua o 100 mau kānaka, a he 10 mau kānaka he poʻe loea.Ua hoʻokumu mākou i kahi laina hana kūpono no ka noiʻi, ka hoʻokolohua hoʻokele, a me ka hana nui, a hoʻokumu pū i ʻelua labs, a hoʻokahi kikowaena hoʻāʻo.Hoʻāʻo mākou i kēlā me kēia huahana ma mua o ka lawe ʻana e hōʻoia i ka hāʻawi ʻana i ka huahana maikaʻi i kā mākou mea kūʻai.

Hoʻokipa mākou i nā mea kūʻai mai ke ao holoʻokoʻa e kipa i kā mākou hale hana a hoʻokumu i kahi hui maikaʻi!

Aia kekahi ʻōlelo kahiko ma Kina e hauʻoli nui mākou i ka ʻike ʻana i nā hoaaloha a me nā mea kūʻai mai nā wahi a pau o ka honua!

Ua hala kā mākou hui i ka ʻōnaehana hoʻokele o ISO 9001, a loaʻa iā mākou kā mākou ʻōnaehana SOP no ka hana ʻana, kūʻai aku, a ma hope o ka lawelawe kūʻai!Manaʻolana hiki iā mākou ke hāʻawi i kahi lawelawe maikaʻi a ʻoihana no ʻoe!
Hoʻolaha Kūʻai

Welina mai nā mea kūʻai aku mai ka honua holoʻokoʻa!
Loaʻa iā mākou nā mea kūʻai ma ka honua holoʻokoʻa, a hiki i kēia manawa, ua hoʻokumu i kahi hui maikaʻi me sumsung, LG, LV, a me nā mea kūʻai aku he nui pū kekahi, a no ka ʻike hou aku, e ʻoluʻolu e kelepona mai iā mākou!
FAQ
1) Hana ʻoe a kālepa paha?

He mea hana mākou, aia kā mākou hale hana ma Shandong, akā hiki iā mākou ke hāʻawi i kahi lawelawe kūʻai kūʻai hoʻokahi no ʻoe!
2) Nā huaʻōlelo uku: T / T (telex transfer), Western Union, MoneyGram, BTC (bitcoin), etc.3) Lead time≤25kg: i loko o ʻekolu mau lā hana ma hope o ka loaʻa ʻana o ka uku.>25kg: hoʻokahi pule
4) SampleAvailable, hiki iā mākou ke hāʻawi i nā mea liʻiliʻi liʻiliʻi liʻiliʻi no ka loiloi maikaʻi! 5) Package1kg no kēlā me kēia ʻeke fpr samples,

25kg a i ʻole 50kg no ka pahu, a i ʻole e like me kāu e koi ai.6)StorageStore e paʻa paʻa i ka pahu ma kahi maloʻo, ʻoluʻolu a maikaʻi.
