Nā hiʻohiʻona:
Aia ʻo Boron ma kahi kūikawā ma waena o ka metala a me ka nonmetal ma ka papa ʻaina o nā mea. ʻOi aku ka ikaika o kāna mau mea kemika ma muli o ka uila maikaʻi ʻole, ka radius atomika liʻiliʻi a me ka hoʻoili nuklea kikowaena. Paʻa ia i ka mahana maʻamau, hoʻokahe ʻia i ka wā e hoʻomehana ai i 300 ℃, a puhi ʻia inā wela a 700 ℃. Ua like kona waiwai ole me ke silika. Hiki i ka Boron ke launa pū me ka oxygen, nitrogen, sulfur, halogen a i ʻole carbon etc. Hiki ke hoʻohui pololei ʻia me nā ʻano metala he nui e hana i nā pūhui boronic. Eia kekahi, hiki ke hoʻopili ʻia ka boron me nā pūhui mea ola e hoʻohua ai i kekahi mau pūhui, kahi i hoʻohui pono ʻia ka boron me ke kalapona, a i ʻole ka oxygen ma waena o ka boron a me ke kalapona.
Nā noi:
Hoʻohana nui ʻia ʻo Boron i ka metallurgy, electronics, lāʻau lapaʻau, ceramics, nulear industry and chemical industry etc. Hiki ke hoʻohana ʻia i ka hoʻoheheʻe ʻana i kekahi mau kila kila kūikawā a me ka mea hoʻohemo kinoea no ke kila hoʻoheheʻe ʻana, i loko o ka pahu ahi e hoʻoheheʻe ʻia i ka ʻoihana, i ka lāʻau hoʻomalu o ka atomic reactor, a i ka ikaika kiʻekiʻe. wahie no ka rocket. He mea koʻikoʻi ia no ka hana ʻana i nā halogenatedboron maʻemaʻe kiʻekiʻe, a he mea hoʻi no ka hana ʻana i nā ʻano huila boronic. Hiki ke hoʻololi a mālama ʻia ka nui o nā metala hanohano. Hiki ke hoʻohana ʻia ʻo Boron a me kāna mau mea hoʻohui e like me ka catalyst no kekahi mau mea hoʻonaninani kūlohelohe, a pēlā aku.
Pūʻolo:
Hoʻopili ʻia kāna ʻeke i loko o nā ʻeke alumini alumini, kahi i waiho ʻia ai ka ʻeke plastik.
Uuna paona 1kg ka eke, 5kg/pahu, 10kg/pahu, 25kg/pahu
Waihona:
Pono e mālama ʻia i loko o kahi malu, ventilating a maloʻo hale kūʻai. Hoʻokahi makahiki kona ola mālama.
Hiki ke hoʻohana ʻia ka huahana inā hiki i ka maʻamau ma o ka hoʻāʻo hou ʻana ma hope o ka lā i ʻōlelo ʻia.
Nā memo palekana:
ʻO ka huahana i manaʻo ʻia he mea ʻawaʻawa ma ka inhaling a me ka ʻai ʻana, ʻo ka inhale e loaʻa ka hopena i ke kikowaena o ka ʻōnaehana, ʻo ka ʻai ʻana e alakaʻi i ka hoʻoulu ʻana o ka ʻōpū a me ka ʻōpū a me ka boron poisoning, e hoʻopili me ka ʻili a i ʻole nā maka e alakaʻi i ka hoʻoulu liʻiliʻi. , pono e komo i nā makaaniani pale pale, pale pale lepo lepo, nā mīkina lima lima i ka wā e lawelawe ana.
