Kamoo Sieve ea Molek'hule e Sebetsang Kateng

Thepa e sebelisoang ka har'a sieve ea limolek'hule ea indasteri e na le li-pores tse nyane tse tšoanang. Ha lintho tse ling li kopana le sefe ea limolek'hule, limolek'hule tse lekanang le boholo bo lekaneng hore li kene ka har'a masoba li tla ba adsorbed. Limolek'hule tse kholo haholo hore li ka lekana li ke ke tsa. Li-sieve tsa limolek'hule li sebetsa boemong ba microscopic, ka hona boholo ba tsona bo lekanngoa ka li-angstrom. Bophahamo ba pore 3Å le 4Å bo tla khahlisa metsi ha boholo bo tlosa li-hydrocarbon tse kholoanyane.

Lisebelisoa tsa Sieve ea Molek'hule

Ka kutloisiso e tiileng ea mahlale, li-desiccant tse ngata tsa tlhaho tse kang lime, letsopa le gel ea silika le tsona li sebetsa ka ho sefa limolek'hule tsa mouoane oa metsi, empa li-sieve tsa khoebo tsa limolek'hule li entsoe ka li-aluminosilicate tsa maiketsetso tsa crystalline. Ho fapana le li-desiccants tse fumanoang tlhahong, taolo ea boholo ba pore nakong ea tlhahiso e hlahisa litšobotsi tse khethollang tsa adsorption.

Li-sieve tsa limolek'hule li atisa metsi ka potlako ho feta li-dryer tse ling tsa desiccant 'me li ka fokotsa mongobo ho ea maemong a tlaase haholo ho feta gel e tloaelehileng ea silica. Li boetse li sebetsa ho feta li-desiccants tsa tlhaho bakeng sa likopo tse fetang mocheso o tloaelehileng oa kamore. Ha li sebelisoa hantle, li ka sebetsa hantle ho fokotsa limolek'hule tsa metsi ka tlase ho 1ppm ka lijaneng tse khethehileng kapa ho isa ho 10% ea mongobo o amanang le sephutheloana.

Litheko li phahame ho feta mefuta e meng ea desiccant desiccant dehumidification; leha ho le joalo, li-sieve tsa limolek'hule le tsona li sebetsa hantle haholoanyane. Litšenyehelo tsa 'nete ka yuniti ka 'ngoe le boleng ba ho qetela li tla ipapisa le lintlha tse ling tse kang bophahamo ba metsi bo tla tlosoa le boemo ba ho omella bo hlokahalang. Li-sieve tsa limolek'hule, leha li lumelletsoe ho sebelisoa le meriana Europe, ha li so amoheloe ke FDA bakeng sa lijo kapa meriana ea US.

Li-sieve tsa limolek'hule li na le bokhoni bo botle haholo bakeng sa le litekanyetso tsa adsorption, esita le mocheso o phahameng. Ke tsona feela desiccant e khethang boholo ba limolek'hule.
