ʻO ka Magnesium oxide kahi mea hoʻoheheʻe metala honua alkaline maʻamau, ʻano hoʻohālikelike MgO.ʻO ka pauka keʻokeʻo, ka helu heheʻe 2852 ℃, kahi paila 3600 ℃, ka mānoanoa pili o 3.58 (25 ℃).Hiki ke hoʻoheheʻe ʻia i ka ʻakika a me ka paʻakai ammonium.Hiki i kāna hana lohi me ka wai ke hana i ka magnesium hydroxide.Hiki ke hoʻoheheʻe ʻia i loko o ka hopena wai kalapona e hana ai i ka magnesium bicarbonate.I ka lewa, hiki iā ia ke komo mālie i ka makū a me ka carbon dioxide.Hoʻokuʻu ka wela i nā uahi hoʻonāukiuki.ʻO Magnesite (MgCO3), dolomite (MgCO3 • CaCO3) a me ka wai kai ka mea nui no ka hana ʻana i ka magnesium oxide.
Hoʻokaʻawale ʻia ka magnesium oxide i ʻelua ʻano o ka magnesium oxide māmā a me ka magnesium oxide kaumaha.He lax ka nui o ka magnesium oxide, ka pauda amorphous keʻokeʻo.ʻAʻala ʻole, ʻono ʻole a ʻaʻohe mea ʻawaʻawa.ʻO ka mānoanoa 3.58g/cm3.hiki ʻole ke hoʻoheheʻe ʻia i ka wai maʻemaʻe a me ka mea hoʻoheheʻe organik.ʻO ka nui o ka magnesium oxide he paʻa, keʻokeʻo a i ʻole ka pauka beige.Hoʻohana nui ʻia ka magnesium oxide maikaʻi no ka lubricant kiʻekiʻe, ka ʻili tanning kiʻekiʻe e hoʻokiʻekiʻe ana i ka pae alkali, ka meaʻai, ka lāʻau lapaʻau, ke kila kila silika, ka papa electromagnetic kiʻekiʻe, ka magnesium oxide maʻemaʻe kiʻekiʻe a kokoke i ʻumi mau ʻano o ka haku mele.
ʻO ka hoʻohana ʻana i ka magnesium oxide:
1, Hoʻohana ʻia kekahi o ka hoʻohana nui ʻana o ka magnesium oxide ma ke ʻano he lapalapa ahi, nā mea hoʻopaʻa ahi maʻamau, hoʻohana nui ʻia nā polymers me nā halogen a i ʻole nā mea halogen-containing flame retardants i hui pū ʻia i loko o kahi hui pū.
2, hiki ke hoʻohana ʻia kahi hoʻohana ʻē aʻe o ka magnesium oxide e like me ka neutralizing agent, magnesium oxide alkaline, maikaʻi adsorption performance, hiki ke hoʻohana ʻia e like me ke kinoea hoʻoheheʻe ʻia, ka wai hoʻomaʻemaʻe wai, nā metala kaumaha a me ka mālama ʻana i ka ʻōpala a me nā mea hoʻonaninani ʻē aʻe, me nā koi o ke kaiapuni, ke ulu wikiwiki nei ka noi kūloko.
3, hiki ke hoʻohana ʻia ke kaomi o ka magnesium oxide maikaʻi e like me nā uhi optical.ʻO ka mānoanoa o ka uhi ʻana ma waena o 300nm a me 7mm, akaka ka uhi.1mm ka mānoanoa o ka uhi ʻana i ka helu refractive o 1.72.
4, hoʻohana ʻia no ka hoʻohana ʻana i ka pōhaku piʻi, hiki ke hoʻopaʻa i ka hou lima, (E hoʻomaopopo: hiki i ka inhalation o ka uahi magnesium oxide ke alakaʻi i ka maʻi smog metala.)
5, hoʻohana nui ʻia no ka hoʻomākaukau ʻana i nā lāʻau lapaʻau kūloko e hoʻokaʻawale i ka nui o ka ʻōpū.ʻO nā mea hoʻomākaukau maʻamau: waiu magnesium - emulsion;nā papa uhi magnesium - aia i kēlā me kēia ʻāpana MgO0.1g,;ka hoʻopuehu ʻana i ka waikawa - magnesium oxide a me ka sodium bicarbonate i hui ʻia i loko o ka nui, etc.
6, hoʻohana nui ʻia ka magnesium oxide ma ke ʻano he mea maka no ka hoʻomākaukau ʻana i nā ceramics, enamel, refractory crucible a me refractory bricks.Hoʻohana pū ʻia e like me ka mea hoʻopili abrasive a me ka hoʻopiha pepa, neoprene a me ka fluorine rubber promoter a me ka mea hana
