Sieves ea molek'hule: Ithute ka Lisebelisoa le Tšebeliso ea Bona

 

tsebisa

 Lisefa tsa molek'hule, eo hape e tsejoang e le li-zeolite tsa maiketsetso, ke lisebelisoa tsa porous tse khethang limolek'hule ho latela boholo ba tsona le polarity. Thepa ena e ikhethang e lumellali-sieve tsa molek'huleho fumana mefuta e mengata ea lisebelisoa liindastering tse fapaneng. Sehloohong sena, re tla hlahlobisisa potso e reng "Lisefa tsa molek'hule li sebelisetsoa eng?" le ho hlahloba lisebelisoa tse ling tse tloaelehileng ka botlalo.

 

Lisebelisoa tsa indasteri

E 'ngoe ea lisebelisoa tsa bohlokoa ka ho fetisisa tsa li-sieve tsa limolek'hule ke indastering ea khase le oli. Lisefa tsa limolek'hule li phetha karolo ea bohlokoa ho tloseng mongobo le litšila khase ea tlhaho, e leng se etsang hore e tšoanelehe bakeng sa lipalangoang le ho sebelisoa. Ka ho tšoanang, li-sieve tsa limolek'hule li sebelisoa mekhoeng ea ho ntša ethanol 'meleng le ho hloekiseng li-hydrocarbon, e leng ho nolofalletsang ho hlahisa mafura le lik'hemik'hale tsa boleng bo phahameng.

Ntle le moo, li-sieve tsa limolek'hule li sebelisoa haholo lits'ebetsong tsa karohano ea moea, ho kenyelletsa tlhahiso ea naetrojene, oksijene le likhase tse ling tsa indasteri. Matla a adsorption a li-sieve tsa limolek'hule a thusa ho arola oksijene moeeng, ho hlahisa oksijene e hloekileng haholo e finyellang litlhoko tsa liindasteri tse ngata tse kenyeletsang tlhokomelo ea bophelo bo botle, welding le tšepe.

Ka indasteri ea petrochemical,li-sieve tsa molek'hulesebetsa joalo ka li-catalysts kapa adsorbents nakong ea phetoho le lits'ebetso tsa tlhoekiso. Li thusa ho tlosa litšila tse kang sebabole le carbon dioxide le ho ntlafatsa ts'ebetso ea li-catalysts, ho ntlafatsa tlhahiso ea lik'hemik'hale le libeso.

Tšebeliso ea tikoloho

Bokhoni ba limolek'hule tsa li-sieve tsa ho kenya limolek'hule tsa metsi ho tsoa ho maro le likhase li etsa hore e be tsa bohlokoa lits'ebetsong tse fapaneng tsa tikoloho. Ka mohlala,li-sieve tsa molek'huleli sebelisoa lihatsetsing le tsamaisong ea ho futhumatsa moea ho tlosa metsi, kahoo li thibela ho bola le serame.

 

Ho phaella moo, li-sieve tsa limolek'hule li sebelisoa haholo e le li-desiccants ka thepa ea ho paka ho boloka lihlahisoa tse kang meriana le lisebelisoa tsa elektronike li omme. Thepa ea hygroscopic ea li-sieve tsa limolek'hule e netefatsa paballo ea boleng le ho lelefatsa bophelo ba shelofo ea lihlahisoa tsena tse hlokolosi.

 

likopo tsa bongaka

Lefapheng la bongaka,li-sieve tsa molek'hulephetha karolo ea bohlokoa ho hlahiseng oksijene ea bongaka le ho tlosa carbon dioxide moeeng o ntšitsoeng nakong ea anesthesia. Ba thusa ho laola likhase tsa bongaka ka mokhoa o sireletsehileng le ka katleho, ho ntlafatsa tlhokomelo ea bakuli.

 

ha re phethela

Ka bokhutšoanyane, li-sieve tsa limolek'hule li na le mefuta e mengata ea lisebelisoa 'me ke lisebelisoa tsa bohlokoa ho khase ea tlhaho, petroleum, petrochemical, tšireletso ea tikoloho, bongaka le liindasteri tse ling. Bokhoni ba bona ba ho khetha limolek'hule tse ipapisitseng le boholo le polarity li etsa hore e be tsa bohlokoa bakeng sa lits'ebetso ho tloha ho felloa ke metsi 'meleng le tlhoekiso ho isa karohanong ea moea le karabelo e matla. Ha tlhoko ea bohloeki, theknoloji e sebetsang hantle haholoanyane e ntse e hola, li-molecular sieve e ntse e le karolo ea bohlokoa lits'ebetsong tse ngata tsa indasteri le tikoloho.
