Cov khoom siv
Nws feem ntau yog dov los ntawm cov hlau thiab tuaj yeem ua rau hauv lub diaphragm (hu ua zaj duab xis) thiab ib lub raj membrane (hu ua raj). Cov zaj duab xis thickness feem ntau yog 50 mus rau 100 microns. Nws yog tsuas yog siv rau kev ua kom huv ntawm cov pa oxygen, thiab nws txoj cai yog kev daws teeb meem-diffusion hom, thiab lub zog tsav ntawm diffusion yog ib feem ntawm qhov sib txawv ntawm hydrogen ntawm ob sab ntawm daim nyias nyias. Ntawm 300-500C, thaum cov khoom siv raw hydrogen yog pressurized rau hauv ib sab ntawm zaj duab xis, cov hydrogen molecule thawj chemically adsorbs thiab dissociates rau hauv hydrogen atoms ntawm cov zaj duab xis, tom kawg dissolves nyob rau hauv cov alloy los tsim hydrides, thiab cov me me. hydrogen atoms nyob rau hauv qhov sib txawv ntawm cov alloy lattice thiab tuaj yeem txav tau yooj yim. Tsav los ntawm qhov concentration gradient, hydrogen atoms diffuse mus rau lwm sab ntawm daim nyias nyias thiab precipitate tawm, recombining rau hauv hydrogen molecules thiab desorption. Ntxiv nrog rau hydrogen thiab nws cov isotopes, tsis muaj lwm yam roj tuaj yeem dhau los ntawm daim nyias nyias, yog li cov ntaub thaiv npog tuaj yeem siv tau kom tau txais ultra-high purity hydrogen. Tus nqi ntawm hydrogen transmembrane muaj feem xyuam rau qhov kub thiab txias, zaj duab xis thickness thiab hydrogen ib nrab siab sib txawv P ntawm ob sab ntawm zaj duab xis. Ua kom kub, ua rau tib neeg P thiab txo cov yeeb yaj kiab tuab tuaj yeem ua kom cov hydrogen permeability. Txawm li cas los xij, yog tias qhov kub thiab txias heev, nws yuav ua rau kom muaj zog noj thiab txo lub cev lub zog ntawm zaj duab xis. Yog li ntawd, qhov kub thiab txias feem ntau yog tswj ntawm ib ncig ntawm 400C. Qee qhov impurities tuaj yeem ua rau cov kab mob lom, txo cov ammonia permeability ntawm daim nyias nyias, thiab tseem ua rau cov membrane puas. Lead lom tuaj yeem tshwm sim los ntawm mercury, arsenide, halide, roj vapor, sulfur thiab ammonia tshuaj thiab hmoov av. Aluminium alloy tuaj yeem ua rau hauv cov raj (tubes) lossis diaphragms (films).
