ʻAka Boric

wehewehe pōkole:

He pauda crystalline keʻokeʻo, me ka ʻoluʻolu a me ka ʻala ʻole.ʻAʻole i hāʻawi wale ʻia nā protons i kāna kumu waikawa.No ka mea ʻo ka boron he ʻātoma hemahema electron, hiki iā ia ke hoʻohui i nā ion hydroxide o nā mole wai a hoʻokuʻu i nā protons.Ke hoʻohana nei i kēia waiwai hemahema electron, hoʻohui ʻia nā pūhui polyhydroxyl (e like me ka glycerol a me ka glycerol, etc.) e hana i nā paʻa paʻa e hoʻoikaika i ko lākou ʻakika.

Hoʻohana ʻia no ka hana ʻana i ke aniani optical, ke aniani kūpaʻa ʻakika, ke aniani organoborate a me nā aniani kiʻekiʻe a me ke aniani fiber, hiki ke hoʻomaikaʻi i ka pale wela a me ke aniani o ke aniani, hoʻomaikaʻi i ka ikaika mechanical, pōkole ka manawa hoʻoheheʻe.Hoʻokani ʻo B2O3 i ka hana ʻelua o ka flux a me ka hoʻokumu ʻana i ka pūnaewele i ka hana ʻana i ke aniani a me ke aniani.No ka laʻana, i ka hana aniani fiber, hiki ke hoʻohaʻahaʻa i ka mahana heheʻe e hoʻomaʻamaʻa i ke kaha kiʻi uea.Ma keʻano laulā, hiki i ka B2O3 ke hoʻemi i ka viscosity, hoʻomalu i ka hoʻonui ʻana i ka wela, pale i ka permeability, hoʻomaikaʻi i ke kūpaʻa kemika, a hoʻomaikaʻi i ke kūʻē ʻana i ka haʻalulu mechanical a me ka haʻalulu wela.Ma ka hana aniani kahi e pono ai ka sodium haʻahaʻa, hui pinepine ʻia ka waika boric me ka sodium borates (e like me ka borax pentahydrate a i ʻole borax anhydrous) e hoʻoponopono i ka ratio sodium-boron i ke aniani.He mea nui kēia no ke aniani borosilicate no ka mea hōʻike ka boron oxide i ka solubility maikaʻi i ka hihia o ka sodium haʻahaʻa a me ka alumini kiʻekiʻe.

Enamel/ceramic

ʻO ka enamel, ʻoihana seramika no ka hana ʻana i ka glaze, hiki ke hōʻemi i ka hoʻonui wela o ka glaze, e hoʻemi i ka mahana hoʻōla o ka glaze, i mea e pale ai i ka haki ʻana a me ka deglazing, hoʻomaikaʻi i ka luster a me ka wikiwiki o nā huahana.No nā aniani a me ka enamel glazes, ʻo ka boron oxide kahi kahe maikaʻi a me ke kino hana pūnaewele.Hiki iā ia ke hana i ke aniani (ma nā haʻahaʻa haʻahaʻa), hoʻomaikaʻi i ka adaptability o blank glaze, hoʻemi i ka viscosity a me ka ʻili o ka ʻili, hoʻomaikaʻi i ka refractive index, hoʻomaikaʻi i ka ikaika mechanical, durability and wear resistance, he mea nui ia o ka glaze lead-free.ʻOka koke ka boron frit kiʻekiʻe a hoʻoheheʻe wikiwiki ʻia, kahi kūpono i ke kala ʻana.I loko o ka frit i hoʻoheheʻe ʻia me ka wikiwiki, ua hoʻokomo ʻia ʻo B2O3 ma ke ʻano he boric acid e hōʻoia i ka haʻahaʻa o ka sodium maʻiʻo.

ʻOihana mālama ola kino

Hoʻohana ʻia i ka hana ʻana i ka ʻaila boric acid, disinfectant, astringent, preservative a pēlā aku.

Paʻa ahi

ʻO ka hoʻohui ʻana i ka borate i ka mea celluloid hiki ke hoʻololi i kona hopena oxidation a hoʻoikaika i ka hoʻokumu ʻana o ka "carbonization".No laila, he pale ahi.ʻO ka waikawa Boric, hoʻokahi a i hui pū ʻia me ka borax, he hopena kūikawā i ka hoʻohaʻahaʻa ʻana i ka flammability o ka insulation celluloid, ka lāʻau, a me nā kaila pulupulu i nā moena.

Hoʻohana ʻia ia e like me ka additive a me ka cosolvent i ka hana ʻana i ke kila boron e hana i ke kila boron i kiʻekiʻe paʻakikī a me ka ductility ʻōwili maikaʻi.Hiki i ka waika Boric ke pale i ka hoʻoheheʻe ʻia o ka wili metala, brazing a me ka hoʻoheheʻe casing.ʻO ia hoʻi ka mea maka o ka ferroboron alloy.

ʻOihana kemika

Hoʻohana ʻia i ka hana ʻana o nā borates like ʻole, e like me ka sodium borohydride, ammonium hydrogen borate, cadmium borotungstate, potassium borohydride a pēlā aku.I ka hana ʻana i nā intermediates nylon, hoʻokani ka waikawa boric i ka hana catalytic i ka hoʻoheheʻe ʻana o nā hydrocarbons a hoʻoulu i nā esters e hoʻonui i ka hua o ka ethanol, a laila e pale ai i ka hoʻoneʻe hou ʻana o nā pūʻulu hydroxyl e hana i nā ketones a i ʻole hydroxic acid.ʻO ka ʻoihana fertilizer no ka hana ʻana i nā wicks candle, boron i loko o ka momona.Hoʻohana ʻia ia ma ke ʻano he reagent kemika analytical no ka hoʻomākaukau ʻana i ka buffer a me nā ʻano media like ʻole no ka hānau ʻana haploid.
