Pehea e hāʻawi ai ka Boron Nitride Powder i ka Lubrication mau ma lalo o ka wela

Nā Manaʻo Koʻikoʻi

• Hāʻawi ka pauka Boron nitride lubrication hilinaʻi i ka wela nui, e mālama ana i ka hana a hiki i ka 3000 °C i nā wahi naikokene.
• ʻO kāna ka helu haʻahaʻa haʻalulu hoʻemi i ke komo ʻana a me ka haehae ʻana ma nā mīkini, e hōʻoiaʻiʻo ana i ka hana maʻalahi a me ke ola lōʻihi o nā lako.
• ʻO ka inertness kemika o Boron nitride e ʻae iā ia e kūʻē i nā hopena me nā kemika ʻino, e kūpono ai no nā noi wela kiʻekiʻe ma nā ʻoihana like ʻole.

No ke aha e hoʻohana nui ʻia ai ʻo Boron Nitride i nā ʻōnaehana Lubricant kiʻekiʻe

ʻAno a me ke kūpaʻa wela o ka pauka Boron Nitride

Hiki iā ʻoe ke hilinaʻi i ka pauka boron nitride e mālama i kona ʻano ʻoiai ke kau ʻia i ka wela nui. ʻO ke ʻano hexagonal, i kapa pinepine ʻia ʻo "white graphite," hāʻawi iā ia i kahi ʻōnaehana ikaika a paʻa. Kōkua kēia ʻano i ka pauka e pale aku i ka haki ʻana i nā mahana kiʻekiʻe. ʻIke ʻoe i kēia ma kona hiki ke lawelawe i ka wela a hiki i 3000 °C i loko o ka lewa nitrogen a hiki i 2000 °C i nā kūlana kūlike ʻole. Hoʻohālikelike pū ka pauka me ka quartz i ka hoʻonui ʻana o ka thermal akā he ʻumi manawa ka conductivity thermal. ʻO ke ʻano kēia e hoʻolaha koke a like ka wela, kahi e pale ai i kāu lako mai ka wela nui.

Eia kahi papa e hōʻike ana i ke ʻano o ka pauka boron nitride e kū nei i ka pale wela a me nā waiwai wela:

Hiki iā ʻoe ke ʻike i ke kumu o ka boron nitride hoʻohana nui ʻia i ka mahana kiʻekiʻe nā ʻōnaehana lubricant. ʻO kona ʻano a me ke kūpaʻa wela e lilo ia i koho kiʻekiʻe no nā hana paʻakikī.

Ua wehewehe ʻia ka haʻalulu haʻahaʻa a me ka inertness kemika

Ke hoʻohana ʻoe i ka pauka boron nitride, loaʻa iā ʻoe kahi mea e paheʻe maʻalahi a ʻaʻole e pane me ka hapa nui o nā kemika. He haʻahaʻa ka coefficient friction o ka pauka, ʻo ia hoʻi ke neʻe mālie nei nā ʻāpana e neʻe ana ma luna o kekahi. Kōkua kēia i ka hōʻemi ʻana i ka ʻaʻahu a me ka haehae ʻana i kāu mau mīkini. ʻOiai i nā mahana kiʻekiʻe e like me 1000 °C i nā wahi oxidizing, mālama ka boron nitride i kona mana lubricating.

Hoʻohana nui ʻia ka Boron nitride i nā ʻōnaehana lubricant wela kiʻekiʻe no ka mea e kūpaʻa ana ia a ʻaʻole e pane me nā kemika ʻino. Eia kekahi mau ʻoiaʻiʻo e pili ana i kāna ʻano kemika:

• Hōʻike ka pauka boron nitride i ke kūpaʻa kemika kupaianaha.
• ʻAʻole ia e hoʻomaʻū i ka hapa nui o nā metala a me nā aniani i hoʻoheheʻe ʻia.
• Noho paʻa nō ia ʻoiai ke hōʻike ʻia i nā reagents hoʻonāukiuki he nui.
• ʻO kona ʻano kūikawā a me kona nui e lilo ia i mea pono i nā ʻoihana he nui.
• Loaʻa ia i nā ʻano he nui, e like me hexagonal, cubic, a me wurtzite, nā mea e kōkua iā ia e hana maikaʻi i nā wahi paʻakikī.

Hiki iā ʻoe ke hilinaʻi i ka boron nitride e hoʻomau i ka holo pono ʻana o kāu lako, ʻoiai ke hāʻule nā ​​​​mea ʻē aʻe.

Hoʻohālikelike ʻia me nā Lubricants Kuʻuna

E noʻonoʻo paha ʻoe pehea e hana ai ka boron nitride hoʻohālikelike ʻia me nā lubricants ʻē aʻe e like me ka graphite a i ʻole molybdenum disulfide. Hoʻohana nui ʻia ka Boron nitride i nā ʻōnaehana lubricant wela kiʻekiʻe no ka mea ʻoi aku ka maikaʻi o kēia mau koho kuʻuna ma nā ʻano he nui.

• Hoʻomau ka hana ʻana o ka hexagonal boron nitride (h-BN) a hiki i 800 °C i nā wahi oxidizing, ʻoiai ʻo ka molybdenum disulfide e haki koke.
• Hiki i nā lubricants boron nitride ke hoʻokele i nā mahana a hiki i 1200 °C ma nā kūlana oxidizing, ʻoi aku ke kiʻekiʻe ma mua o ka graphite a i ʻole molybdenum disulfide.
• Kūʻē nā mea hoʻoluʻu HBN i ka oxidation a me ka thermal breakdown, no laila e lōʻihi ko lākou ola i nā wahi wela.
• Ua nalowale ka pono o ka Graphite i nā mahana kiʻekiʻe no ka mea he maʻalahi ka oxidize.

Ke pono ʻoe i kahi lubricant e hiki ke lawelawe i ka wela, kūʻē i nā kemika, a hoʻomau i ka hana ma lalo o ke kaomi, hoʻohana nui ʻia ka boron nitride i nā ʻōnaehana lubricant wela kiʻekiʻe no kekahi kumu. Hāʻawi ia iā ʻoe i ka hana hilinaʻi kahi hiki ʻole i nā lubricants ʻē aʻe.

Nā Hoʻohana Honua Maoli a me ka Hoʻohana Kūpono

Nā Hoʻohana ʻOihana ma nā Kaiapuni Wela Kiʻekiʻe

E ʻike ʻoe i ka pauka boron nitride ma nā ʻoihana he nui e pono ai lubrication hilinaʻi i nā mahana kiʻekiʻeʻO kona mau waiwai kūikawā e lilo ia i koho kiʻekiʻe no nā hana paʻakikī. Hiki iā ʻoe ke ʻike pehea e hoʻohana ai nā ʻāpana like ʻole i ka pauka boron nitride ma ka papa ma lalo nei:

E ʻike pū ʻoe i ka pauka boron nitride i ka aerospace a me ka pale kaua. Mālama ia i nā pale wela, nā uhi nozzle, a lubricant i nā ʻenekini rocket a me nā satelite. I ka hana ʻana i ka metala, hana ia ma ke ʻano he mea hoʻokuʻu i ka hoʻolei ʻana a kōkua i ka hōʻemi ʻana i ka friction a me ke komo ʻana i ka mīkini.

Hoʻohana nui ʻia ʻo Boron Nitride i nā ʻōnaehana lubricant wela kiʻekiʻe no ka mea hāʻawi ia kūpaʻa wela kiʻekiʻe, haʻahaʻa haʻalulu, a me ka inertness kemika. Kōkua kēia mau ʻano i ka hoʻolōʻihi i ke ola o kāu lako. Ke hoʻohana ʻoe i nā uhi boron nitride, loaʻa iā ʻoe:

• Ke kūpaʻa wela kiʻekiʻe no nā ʻano kaiapuni koʻikoʻi
• ʻOi aku ka lubrication a me nā waiwai non-whole e hōʻemi ana i ka friction a me ke komo ʻana
• Ka palekana ʻana mai ka oxidation a me ka corrosion

Nā ʻAno Hoʻonohonoho a me nā Hana Noi

Hiki iā ʻoe ke hoʻohana i ka pauka boron nitride ma nā ʻano he nui e loaʻa ai ka lubrication maikaʻi loa. ʻO ke ʻano hana a me ke ʻano kūpono e kōkua iā ʻoe e hoʻokō i ka uhi like a me ka hana lōʻihi. Hōʻike ka papa ma lalo nei i nā ʻano hoʻopihapiha maʻamau a me kā lākou lakio i ʻōlelo ʻia:

Hiki iā ʻoe ke hoʻopili i ka pauka boron nitride me ka hoʻohana ʻana i kekahi mau ʻano:

Manaʻo kōkua: No nā hopena maikaʻi loa, e koho i ka nui kūpono o ka ʻāpana a me ka lakio hui no kāu noi. E mālama i kāu pauka boron nitride ma kahi maloʻo a anuanu e mālama ai iā ia i ke kūlana kiʻekiʻe loa.

Ke lanakila nei i nā pilikia Lubrication maʻamau

Hoʻokumu nā wahi wela kiʻekiʻe i nā pilikia lubrication he nui. Hiki iā ʻoe ke kū i ka friction pili, galling, a me nā hemahema o ka ʻili, ʻoiai i ka wā o nā kaʻina hana e like me ka superplastic creation o ka alumini. Hana ʻia ka galling ke pili pū nā ʻili a hōʻino.

Kōkua ka pauka Boron nitride iā ʻoe e hoʻoponopono i kēia mau pilikia. Hana ia ma ke ʻano he pale ikaika ma waena o nā ʻili, e hōʻemi ana i ka friction a pale i ka galling ʻoiai i nā mahana a hiki i 800°C (1472°F). Loaʻa iā ʻoe nā hana maʻalahi a me nā hemahema liʻiliʻi.

• Hoʻemi i ka friction intermetal
• Pale i ka ʻeha a me ka hōʻino ʻana o ka ʻili
• Mālama i nā lako e holo lōʻihi i ka wela nui

Ke hoʻohana ʻoe i ka pauka boron nitride, hiki iā ʻoe ke hilinaʻi i kāu mau mīkini e hana maikaʻi a lōʻihi. Hoʻohana nui ʻia ʻo Boron Nitride i nā ʻōnaehana lubricant wela kiʻekiʻe no ka mea e hoʻoponopono ia i nā pilikia i hiki ʻole i nā mea ʻē aʻe ke lawelawe.

Hiki iā ʻoe ke hilinaʻi i ka pauka boron nitride e hoʻomau i ka holo pono ʻana o nā mīkini, ʻoiai i ka wela nui. ʻO kona mau waiwai kūikawā e hoʻokaʻawale iā ia mai nā lubricants kuʻuna.

• E ʻike ʻoe i ka ulu ʻana o ke koi i nā ʻoihana kaʻa, hana ʻana, a me nā ʻoihana aerospace.
• Makemake nā ʻoihana i ka ʻoi aku ka maikaʻi o ka hana a me ka emi ʻana o ke komo ʻana o nā lako.
• Hoʻokō ka pauka Boron nitride i kēia mau pono me ka hana hilinaʻi.

Nā nīnau i nīnau pinepine ʻia

He aha ka mea e ʻoi aku ai ka maikaʻi o ka pauka boron nitride ma mua o ka graphite no ka lubrication wela kiʻekiʻe?

Loaʻa iā ʻoe ke kūpaʻa wela kiʻekiʻe a me ka inertness kemika me ka boron nitride. Mālama ia i ka mana lubricating i nā mahana kahi e hāʻule ai ka graphite.

Hiki iā ʻoe ke hoʻohana i ka pauka boron nitride i ka meaʻai a i ʻole nā ​​​​​​mea hoʻonani?

ʻAe, hiki iā ʻoe. ʻAʻohe mea ʻawahia ka pauka Boron nitride a palekana no ka hoʻohana ʻana i nā mea hoʻonani a me kekahi mau lako hana meaʻai.

Pehea ʻoe e mālama ai i ka High Purity Hexagonal Boron Nitride Powder?

E mālama i kāu pauka ma kahi anuanu, maloʻo, a me kahi ea. Mālama kēia i ka huahana i ka hou a mālama i kāna hana.
