Hāʻawi mākou i ka maʻemaʻe kiʻekiʻe 99% min Boron Nitride (BN 99%) / Hexagonal Boron Nitride Powder Cas 10043-11-5, me nā hihiʻo like ʻole e like me kēia:
| Nā kikoʻī huahana | Maʻemaʻe % | ʻO ka % o ka mea hiki ʻole ke hoʻoheheʻe ʻia ka hydrogen peroxide | Ka nui o ka oxygen % | % o ka makū | Ka nui o ka granularity (D50) um | Ka nui o ka piula wai, g/cm3 |
| BN-B | 99 | ≤0.5 | ≤0.7 | ≤0.5 | 1 ~ 2 | 0.55 |
| BN-C | 99 | ≤0.5 | ≤0.4 | ≤0.5 | 5 ~ 10 | 0.37 |

HOʻOMANAʻO: ʻO nā ʻōkuhi loea i luna aʻe nei ke hōʻike nei i nā waiwai maʻamau no ka ʻike.
Pūʻolo huahana: 1 kg/ʻeke, ʻeke pepa alumini, 10 kg/pahu pepa (e like me ka noi a nā mea kūʻai aku e hōʻailona i ka lepili)
Boron nitride He kristal ia i haku ʻia me nā ʻātoma naikokene a me nā ʻātoma boron. Ua māhele ʻia ke ʻano kristal i: hexagonal boron nitride (HBN), kokoke i ka hexagonal boron nitride (WBN) a me ka cubic boron nitride. I waena o lākou, ʻo ke kristal o ka hexagonal boron nitride. Loaʻa i ke ʻano he ʻano papa e like me ka graphite, e hōʻike ana i ka pauka keʻokeʻo wehe, lubricating, omo wai, a me ka māmā, no laila ua kapa ʻia ʻo "graphite keʻokeʻo". ʻO ka nui o ke kumumanaʻo he 2.27g/cm3, ʻo ke kaumaha kikoʻī he 2.43, a ʻo ka paʻakikī Mohs he 2.
ʻO ka nitride boron hexagonal Loaʻa iā ia ka insulation uila maikaʻi, ka conductivity thermal. ke kūpaʻa kemika, ʻaʻohe kiko heheʻe maopopo, 3000°C i loko o 0.1MPA nitrogen, i loko o kahi lewa hoʻemi kūlike ʻole, ke kūpaʻa wela a hiki i 2000°C, i hoʻohana ʻia i loko o ka nitrogen a me ka argon hiki i ka mahana ke hiki i 2800°C, ʻaʻole maikaʻi ke kūpaʻa i ka lewa oxygen, a ʻo ka mahana hoʻohana ma lalo o 1000°C. ʻO ke coefficient hoʻonui o ka hexagonal boron nitride ua like ia me ka quartz, akā ʻo ka conductivity thermal he ʻumi manawa o ka quartz. Loaʻa iā ia ka lubricity maikaʻi i nā mahana kiʻekiʻe. He lubricant paʻa wela kiʻekiʻe maikaʻi loa ia me ka hiki ke komo neutron ikaika, nā waiwai kemika paʻa, a me ka inert kemika i aneane nā metala hoʻoheheʻe āpau.
ʻO ka nitride boron hexagonal ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai anuanu. Ke hoʻolapalapa ʻia ka wai, hoʻoheheʻe mālie loa ia a hana i kahi liʻiliʻi o ka waikawa boric a me ka ammonia. ʻAʻole ia e pane me nā waikawa nāwaliwali a me nā kumu ikaika i ka mahana o ka lumi. He mea hoʻoheheʻe iki ia i ka waikawa wela. E hoʻohana i ka sodium hydroxide i hoʻoheheʻe ʻia a me ka potassium hydroxide. Hiki ke hoʻoheheʻe ʻia ka hana ʻana. Loaʻa iā ia ke kūpaʻa nui i ka pala i nā ʻano waikawa inorganic like ʻole, alkalis, nā hopena paʻakai a me nā mea hoʻoheheʻe organik.
ʻO nā kahua noi like ʻole e like me:
| ʻO ka mea hoʻokuʻu ʻōpala no ka hoʻokumu ʻana i ka metala a me ka lubricant no ke kaha kiʻi ʻana i ka uea | Nā mea kū'ē kūikawā ma lalo o ke electrolysis wela kiʻekiʻe | Hiki ke hoʻohana ʻia no nā ʻāpana wela kiʻekiʻe, kaomi kiʻekiʻe, insulation a me ka hoʻopuehu wela | Nā mea hoʻohui anti-wear extrusion lubricant paʻa wela kiʻekiʻe |
|
ʻO ka mea hoʻomaʻemaʻe wela no nā mea hoʻohui polymer ʻē aʻe transistor |
Palekana wela aerospace Mea Hana |
Ma hope o ke kiʻekiʻe o ka mahana a me ke kaomi kiʻekiʻe, hiki ke hoʻololi ʻia i loko o ka cubic boron nitride e like me ka paʻakikī me ka daimana. |
Nā mea hana reactor atomika no ke kūkulu ʻana |
|
Kūpono no ka nozzle mīkini rocket mokulele |
ʻO ke anakahi uila kiʻekiʻe a me ke alapine kiʻekiʻe a me nā mea ʻē aʻe. ka mea hoʻokaʻawale arc ion |
Hoʻohana ʻia ka metallurgical no ke apo hoʻokaʻawale kila hoʻolei mau |
ʻO nā ʻano āpau o ka capacitor film alumini plating |
|
ʻO nā ʻano ʻeke alumini mālama hou a pau a pēlā aku… |
Nā mea hoʻopili wela like ʻole o ka laser anti-counterfeiting alumini plating brand |
Hoʻohana ʻia i nā mea hoʻopihapiha hoʻonani |
Nā mea hoʻohui hoʻonui wela |
★Nā ʻōlelo kuhikuhi palekana: He huahana ʻoihana kēia, ʻaʻole hiki ke ʻai ʻia, pono e ʻaʻahu i nā pale maka palekana a me nā mīkina lima laholio i ka wā e hana ana.
Nā mea e pili ana i ka mālama ʻana a me ka halihali ʻana:
1. ʻAʻole hiki ke lapalapa a pahū kēia huahana a hiki ke mālama ʻia a lawe ʻia e like me nā kemika maʻamau.
2. E mālama i kahi maloʻo a me kahi anu, e pale i ka ua, ka makū, a pale i ka ʻai ʻana ma ke kuhihewa
Inā makemake ʻoe e ʻike i kekahi ʻike hou aku e pili ana i kā mākou Boron nitride, e ʻoluʻolu e leka uila mai iā mākou ma o ka leka uila info@theoremchem.com a i ʻole Whatsapp/Wechat/ Telegram: +86 18321679576
