Biyaha iyo wasakhda ku jirta dareeraha ayaa ah arrimo taban oo ku jira hababka warshadaha, waxayna u baahan yihiin in laga saaro shaandhada molecular zeolite, taas oo loo yaqaan qalajinta dareeraha ama daaweynta dareeraha. Iyada oo cabbirkooda saxda ah ee daloolka iyo xasilloonida kiimikada, shaandhada molecular waxay noqdeen kuwo aan la bedeli karin oo aad waxtar u leh oo loogu talagalay daawaynta dareeraha, gaar ahaan kuwa kiimikada ah iyo warshadaha dawooyinka.
Dhibaatooyinka Caadiga ah ee Daawaynta Xalka
Walxaha warshaduhu waxay inta badan ku jiraan wasakh, sida biyaha xad-dhaafka ah (inta badan iyo kuwa ugu saamaynta badan), walxaha acidic ama alkaline, arrimaha organic, iyo gaaska wasakhda ah (kaarbon dioxide, nitrogen, iyo hydrocarbons) oo la keeno ka dib soo kabashada dareeraha, iwm.
Saamaynta biyahan iyo wasakhda ay ku leeyihiin geeddi-socodka warshadaha waxaa ka mid ah (laakiin aan ku xaddidnayn): faragelinta falcelinta kiimikaad, wax u dhimaya hantida, keenista khataraha deegaanka iyo caafimaadka. Markaa waa in meesha laga saaraa si loo qanciyo shuruudaha habraaca, loogana hortago wax u dhimaya tayada badeecada iyo dib u warshadaynta dareeraha.
Waa maxay sababta shaandhada molecular aan la bedeli karin?
Hufnaanta: Shaandhooyinka molecular waxay leeyihiin awood adsorption aad u saraysa iyo heerka adsorption, taas oo u sahlaysa in ay si wax ku ool ah uga saaraan biyaha dareerayaasha muddo gaaban gudaheed, oo markaa wanaajisa waxtarka qallajinta.
Xulashada: Shaandhooyin molecular ayaa si xushmad leh u xajiya unugyadu wasakhaysan iyada oo aan si weyn u saamaynayn qaybaha kale ee dareeraha. Hantidan la xushay ee adsorption waxay siinaysaa shaandhada molecular faa'iidooyin gaar ah oo ku saabsan hababka daaweynta dareeraha.
Xasilloonida: Maaddada adsorption aad u fiican, shaandhada molecular waxay muujinaysaa xasilloonida kulaylka sare iyo xasilloonida kiimikada, waxayna sii wadi kartaa waxqabadka xayeysiinta ee deggan xaaladaha kala duwan ee hawlgalka iyo xaaladaha dhaqdhaqaaqa.
Dib-u-cusbooneysiin: Shaandhooyin molecular waa walxo deegaanka u wanaagsan, waxqabadkooda xayeysiinta waxaa lagu soo celin karaa habka dib-u-cusbooneysiinta, taas oo u oggolaanaysa dib-u-warshadaynta oo sidaas darteed hoos u dhigista kharashka dhaqaalaha.
Sifooyinka molecular ee Daawaynta millatariga
Nooca 3A Zeolite Molecular Sieve: Ku habboon qalajinta dareerayaasha yaryar ee molecule sida ethanol, methanol, acetone, DMF, THF, iwm. Waxa kale oo loo isticmaali karaa qalajinta dareeraha sida acetonitrile iyo 2-propanol.
Nooca 4A Zeolite Molecular Sieve: Waa wax caadi ah oo la isticmaalo iyo kharash{1} Waxay ku habboon tahay qallajinta dareerayaasha dhexdhexaadka ah sida chloroform, dichloromethane, ether, ethane iyo iwm.
Nooca 5A Zeolite Molecular Sieve: Waxay nuugi kartaa biyaha, carbon dioxide, hydrogen sulfide, iyo molecules yaryar sida alkanes linear. Waxay ku habboon tahay daaweynta dareerayaasha isku dhafan, ka saarida wasakhda dabaysha, iyo kala-soocidda hydrocarbons.
Nooca 13X Zeolite Molecular Sieve: Waxay leedahay cabbir dalool weyn iyo awood sare oo adsorption ah, waxayna ku habboon tahay dabaysha iyo dawaynta millatariga ah ee aan{1} Waxaa si weyn loo isticmaalaa in biyaha iyo wasakhda laga saaro dareerayaasha sida caraf udgoon iyo alkanes.
