Pūʻolo: Aluminum Foil Bag
Waihona: Mālama ʻia ma lalo o nā kūlana maloʻo i hoʻopaʻa ʻia a hoʻokaʻawale ʻia ka hale kūʻai mai nā mea kemika ʻē aʻe.
He aha ka Boron Powder e hoʻohana ai?
Hoʻohana nui ʻia ka pauka Boron i ka metallurgy, electronics, lāʻau lapaʻau, ceramics, nuklea ʻoihana, ʻoihana kemika a me nā māla ʻē aʻe.
1. ʻO ka pauka Boron he ʻano wahie metala me ka gravimetric kiʻekiʻe a me ka volumetric calorific waiwai, i hoʻohana nui ʻia i nā kahua kaua e like me nā propellants paʻa, nā mea pahū ikaika kiʻekiʻe, a me nā pyrotechnics. A ua hoʻemi nui ʻia ka mahana wela o ka pauka boron ma muli o kona ʻano ʻano like ʻole a me ka ʻāpana kikoʻī nui;
2. Hoʻohana ʻia ka pauka Boron ma ke ʻano he mea hoʻohui i loko o nā huahana metala kūikawā e hana i nā alloys a hoʻomaikaʻi i nā ʻano mechanical o nā metala. Hiki ke hoʻohana ʻia e hoʻopaʻa i nā uea tungsten a i ʻole nā mea hoʻopiha i loko o nā composites me nā metala a i ʻole nā ceramics. Hoʻohana pinepine ʻia ʻo Boron i nā mea hoʻoheheʻe spcial no ka hoʻopaʻapaʻa ʻana i nā metala ʻē aʻe, ʻo ia hoʻi nā mea hao wela wela.
3. Hoʻohana ʻia ka pauka Boron ma ke ʻano he deoxidizer i ka hoʻoheheʻe keleawe ʻole o ka oxygen. Hoʻohui ʻia kahi wahi liʻiliʻi o ka pauka boron i ka wā o ka hoʻoheheʻe metala. Ma kekahi ʻaoʻao, hoʻohana ʻia ia e like me ka deoxidizer e pale aku i ka metala mai ka oxidized i ka wela kiʻekiʻe. Hoʻohana ʻia ka pauka Boron ma ke ʻano he mea hoʻohui no nā pōhaku lepo magnesia-carbon i hoʻohana ʻia i nā umu wela wela no ka hana kila;
4. He mea pono no ka Boron Powders i kekahi noi kahi i makemakeia ai na wahi kiekie e like me ka hooponopono wai a ma ka wahie a me ka la. Hoʻopuka pū nā nanoparticles i nā wahi kiʻekiʻe loa.
5. He mea koʻikoʻi ka pauka Boron no ka hana ʻana i ka boron halide maʻemaʻe kiʻekiʻe, a me nā mea ʻē aʻe o ka boron compound; Hiki ke hoʻohana ʻia ka pauka Boron e like me ke kōkua wili; Hoʻohana ʻia ka pauka Boron ma ke ʻano he mea hoʻomaka no nā ʻeke air kaʻa;
