Lithium hydride CAS 7580-67-8 Ubuziranenge bwa 99% nk'ikintu kigabanya
Ibisobanuro by'igicuruzwa
Lithium hydride ni ifu ikomeye cyangwa yera idahinduka umweru, irabagirana, idafite impumuro, ihinduka umukara vuba iyo ihuye n'urumuri. Uburemere bwa molekile = 7.95; Uburemere bwihariye (H2O: 1) = 0.78; Aho ishyuha = 850℃ (ibora munsi y'umuvuduko w'amaraso); Aho ifungirana/ishonga = 689℃; Ubushyuhe bwo kwiyatsa = 200℃. Kumenya ibyago (bishingiye kuri Sisitemu yo Gupima NFPA-704 M): Ubuzima 3, Gutwika 4, Gukora 2. Ifu ikomeye ishobora gukora ibicu by'umukungugu wo mu kirere bishobora guturika iyo ihuye n'umuriro, ubushyuhe, cyangwa oxidizer.
Imiterere y'ibicuruzwa
Lithium hydride (LiH) ni umunyu ukozwe mu cyuma gitukura (kibe ishingiye ku maso) gifite umweru mu buryo bwacyo busanzwe, Nk'igikoresho cy'ubuhanga, ifite imiterere ishimishije mu ikoranabuhanga rinini. Urugero, ingano nini ya hydrogen n'uburemere bworoheje bwa LiH bituma igira akamaro ku birindiro bya neutron n'ibikoresho bipima ingufu za kirimbuzi. Byongeye kandi, ubushyuhe bwinshi bwo kuvanga hamwe n'uburemere bworoheje bituma LiH ikoreshwa mu kubika ubushyuhe ku nganda zikoresha imirasire y'izuba kuri satelite kandi ishobora gukoreshwa nk'ahantu ho gushyushya mu bikorwa bitandukanye. Ubusanzwe, inzira zo gukora LiH zirimo gucunga LiH ku bushyuhe buri hejuru y'aho ishongeshereza (688 DC). Icyuma cya 304L cy'ubwoko bwa stainless steel gikoreshwa mu bice byinshi by'imikorere bikoresha LiH ishongeshejwe.
Lithium hydride ni hydride isanzwe ya ionic ifite litium cations na hydride anions. Electrolysis y'ibintu bishongeshejwe ituma icyuma cya litium kiremwa kuri cathode na hydrogen kuri anode. Uburyo litium hydride-water reaction, butuma gaze ya hydrogen irekurwa, nabwo bugaragaza hydrogen ifite charge mbi.
Lithium hydride ni ifu ikomeye cyangwa yera idahinduka umweru, irabagirana, idafite impumuro, ihinduka vuba iyo ihuye n'urumuri. Lithium hydride nziza ikora kristu zitagira ibara. Iyi poroduro ikoreshwa mu bucuruzi irimo ibizinga by'imyanda, urugero, icyuma cya lithium kitarahinduka, bityo ikaba ibara ryoroheje cyangwa ubururu. Lithium hydride irakomeye cyane mu bushyuhe, ikaba ari yo hydride yonyine ya ionic ishonga idashonga ku gitutu cy'ikirere (mp 688 ℃). Bitandukanye n'izindi hydride za alkali metal, lithium hydride ishonga gato mu bintu bidafite ireme nka ethers. Ikora uruvange rwa eutectic hamwe n'umunyu mwinshi. Lithium hydride irakomeye mu mwuka wumye ariko irashya iyo ubushyuhe bwiyongere. Mu mwuka utose irashya neza mu buryo bwa exothermic; ibintu bigabanyijemo ibice bishobora gushya mu buryo bwikora. Iyo ubushyuhe buri hejuru, ikorana na ogisijeni igakora lithium oxide, hamwe na azote igakora lithium nitride na hydrogen, hamwe na dioxyde de carbone ikora lithium formate.
Porogaramu
Lithium hydride ikoreshwa mu gukora lithium aluminium hydride na silane, nk'ikintu gikomeye gifasha mu kugabanya ubushyuhe, nk'ikintu gifasha mu gukora organic synthesis, nk'isoko yimukanwa ya hydrogen, ndetse n'igikoresho cyoroshye cyo kurinda nucleus. Ubu ikoreshwa mu kubika ingufu z'ubushyuhe ku buryo bw'ingufu zo mu kirere.
Lithium hydride ni kristu y'ubururu-umweru ishobora gushya iyo ibaye ubushuhe. Ikoreshwa nk'isoko y'umwuka wa hydrogen uvamo iyo LiH itose. LiH ni umuti mwiza wo kugabanya ubushyuhe ndetse n'uburinzi burinda imirasire iterwa n'ibikorwa bya kirimbuzi.
Gupakira no Kubika
Gupakira: 100g/agacupa k'ibati; 500g/agacupa k'ibati; 1kg kuri buri gacupa k'ibati; 20kg kuri buri ngoma y'icyuma
Kubika: Bishobora kubikwa mu macupa y'icyuma afite igipfundikizo cyo hanze kugira ngo birindwe, cyangwa mu macupa y'icyuma kugira ngo hirindwe kwangirika kwa mashini. Bika ahantu hatandukanye, hakonje, humutse kandi hafite umwuka mwiza, kandi wirinde cyane ubushuhe. Inyubako zigomba kuba zifite umwuka mwiza kandi zidafite umwuka mwinshi mu nyubako.
