High Purity Palladium tinthu ta mafakitale processing Pd CAS 7440-05-3

Nthawi zambiri amakulungidwa kuchokera ku aloyi ndipo amatha kupangidwa kukhala diaphragm (yotchedwa filimu) ndi chubu cha membrane (chotchedwa chubu). Kuchuluka kwa filimu kumakhala 50 mpaka 100 microns. Amagwiritsidwa ntchito makamaka poyeretsa mpweya, ndipo mfundo yake ndi njira yothetsera kufalikira, ndipo mphamvu yoyendetsa kufalikira ndi kusiyana kwapang'onopang'ono kwa haidrojeni kumbali zonse ziwiri za nembanemba. Pa 300-500C, pamene zopangira hydrogen ndi pressurized mu mbali imodzi ya filimu, molekyulu wa hydrogen choyamba mankhwala adsorbs ndi dissociates mu maatomu wa haidrojeni padziko filimu, yotsirizira amasungunula mu aloyi kupanga hydrides, ndi yaing'ono. maatomu a haidrojeni ali pampata wa alloy lattice ndipo amatha kuyenda momasuka. Moyendetsedwa ndi gradient gradient, maatomu a haidrojeni amafalikira mbali ina ya nembanemba ndikutuluka, ndikuphatikizananso kukhala mamolekyu a haidrojeni ndikuwonongeka. Kuphatikiza pa haidrojeni ndi ma isotopi ake, palibe mpweya wina womwe ungadutse nembanemba, motero nembanemba yankhondo imatha kugwiritsidwa ntchito kupeza haidrojeni yoyera kwambiri. Mlingo wa hydrogen transmembrane umagwirizana ndi kutentha, makulidwe a filimu ndi kusiyana kwapakati pa hydrogen P mbali zonse za filimuyo. Kuwonjezeka kwa kutentha, kuwonjezeka kwa P yaumunthu ndi kuchepa kwa makulidwe a filimu kumatha kukulitsa mphamvu ya haidrojeni. Komabe, ngati kutentha kuli kwakukulu, kumawonjezera mphamvu yogwiritsira ntchito mphamvu ndikuchepetsa mphamvu yakuthupi ya filimuyo. Chifukwa chake, kutentha kumayendetsedwa pafupifupi 400C. Zonyansa zina zimatha kuyambitsa poizoni wa nembanemba, kuchepetsa kuchuluka kwa ammonia mu nembanemba, komanso kuwononga nembanembayo. Poyizoni wamtovu amatha chifukwa cha mercury, arsenide, halide, nthunzi yamafuta, sulfure ndi ammonia ndi fumbi. Aluminiyamu alloy amatha kukhala machubu (machubu) kapena ma diaphragms (mafilimu).
