Mamiriro Ekuita eAluminium Hydroxide uye Yayo Mashandisirwo Ekushandisa

Aluminium hydroxide, sechinhu chakakosha inorganic compound, ine mashandisirwo akawandisa muzvinhu zvesainzi, mushonga, uye kuchengetedza kwezvakatipoteredza. Hunhu hwayo hwakasiyana hwezvimiro hunotaridza chimiro chayo uye chemakemikari zvimiro, izvo zvinozopesvedzera kuita kwayo chaiko kushanda. Nemicroscope, aruminiyamu hydroxide's crystal structure inogona kupatsanurwa kuita marudzi akati wandei, inonyanyozivikanwa iri -mhando ne-rudzi.

-Aluminiyamu hydroxide ine dhizaini, ine aruminiyamu -oxygen octahedra inogovera vertices kuita maviri-mashizha edimensional, ane hydroxide ions achizadza interlayers. Kurongeka uku kunopa izvo zvinhu nzvimbo yakakura uye yakawanda nzvimbo inoshanda, zvichiita kuti ive sarudzo yakanakisa yemashandisirwo akadai seadsorbents uye catalyst inotsigira. Kusiyana neizvi, -Aluminium hydroxide (inozivikanwawo seboehmite) ine orthorhombic structure, ine maaruminiyamu ions akaiswa muoctahedral voids inoumbwa neokisijeni ion nenzira yakarongeka, ichiita matatu{6}}dimensional network framework. Chimiro ichi chinopa kugadzikana kwekushisa kwakawedzerwa uye, kana kuchipisa kusvika pakupisa kwakanyanya, kunogona kuchinjwa kuita corundum{8}}type alumina, zvichiita kuti inowanzoshandiswa sechinhu chinorambidzika kana ceramic precursor.

Mamiriro ekubatanidza pachikamu chemolecular akakosha zvakaenzana. Iyo Al-O bond mualuminium hydroxide ine ionic yakanyanya, asi nekuda kwepolarization yemaaruminiyamu ion, inewo zvimwe zvinoumba covalent. Iyi yakasanganiswa bond pfuma inopa izvo zvinhu zvese imwe dhigirii remagetsi simba uye kureruka kwekuparara kana kuita pasi pemamiriro chaiwo. Zvinonyanya kukosha, kugoverwa kweiyo hydroxide ion muchimiro kunokanganisa zvakananga acidity uye alkalinity yezvinhu. Iyo -mhando, nekuda kwehuwandu hwayo hwepamusoro hwema hydroxyl akafumuka mapoka, haina kusimba acidic uye yakakodzera kune neutralization reactions; iyo -mhando, kune rumwe rutivi, inowanzova nepamusoro pe alkaline, zvichiita kuti ikwane kushandiswa sekuzadza kana kuti insulating zvinhu.

Panyaya yekudzora morphology, iyo synthesis nzira inokanganisa zvakanyanya chimiro chekupedzisira. Semuyenzaniso, iyo hydrothermal method inogona kugadzira fibrous kana rod{{1}shaped aluminum hydroxide, ine aspect ratio inotara kusimbaradza kwechinhu. Iyo yunifomu yekunaya kwemvura nzira inokonzeresa kugadzira zvigadzirwa zvegranular, zvakafanira maapplication akadai seaya ekubatisa matting agents. Mumakore achangopfuura, nanoscale aluminium hydroxide yakakwezva kutarisa nekuda kwehuwandu hwayo hwekuita. Iyo yakasarudzika yepamusoro chimiro che ultrafine particles inoita kuti iratidze hunyanzvi hwepamusoro mune zvinodzosa moto.

Muchidimbu, kusiyana-siyana kwealuminiyamu hydroxide inopa hwaro hwemuchinjika-mashandisirwo ayo. Kunzwisisa kwakadzama kwehukama pakati pekugadzirisa kwekristaro, nzira yekubatanidza, uye morphological maitiro zvinofambisa kugadzirwa kwepamusoro-zvinoita zvekushandisa uye kukurudzira kusimukira kwetekinoroji mumaindasitiri ane hukama. Tsvagiridzo yeramangwana inogona kutarisisa kumisa chimiro chehuwandu-hukama hwekuita kuti uwane dhizaini chaiyo.
