Molecular Sieves: Dzidza Nezve Mashandisirwo Avo uye Mashandisiro

 

introduce

 Masifa emolecular, inozivikanwawo semasynthetic zeolites, zvinhu zvine porous izvo zvinosarudza adsorb mamorekuru zvichienderana nehukuru uye polarity.Iyi yakasarudzika pfuma inobvumiramolecular sieveskuwana huwandu hwakawanda hwekushandisa mumaindasitiri akasiyana siyana.Muchinyorwa chino, tichazama zvakadzama mumubvunzo wekuti "Masefa emokuru anoshandiswa chii?"uye inoongorora mamwe maapplication akajairwa zvakadzama.

 

Industrial applications

Imwe yeanonyanya kukosha mashandisirwo emamorekuru sieves ari mugasi neoiri indasitiri.Masefa emamorekuru anoita basa rakakosha mukubvisa unyoro netsvina kubva mugasi chaiwo, zvichiita kuti ive yakakodzera kutakurwa uye kushandiswa.Saizvozvowo, masefa emamorekuru anoshandiswa mukugadzirisa ethanol dehydration uye mukucheneswa kwemahydrocarbons, zvichiita kuti kugadzirwa kwemafuta emhando yepamusoro nemakemikari.

Uye zvakare, masieve mamorekuru anoshandiswa zvakanyanya mukuparadzanisa mweya maitiro, kusanganisira kugadzirwa kwenitrogen, okisijeni uye mamwe magasi emaindasitiri.Iyo adsorption kugona kwema molecular sieves inobatsira kupatsanura okisijeni kubva kumhepo, ichigadzira yakakwira-kuchena okisijeni inosangana nezvinodiwa nemaindasitiri akawanda anosanganisira hutano, welding uye kucheka simbi.

Muindasitiri ye petrochemical,molecular sievesita semacatalysts kana adsorbents panguva yekushandura uye yekuchenesa maitiro.Vanobatsira kubvisa tsvina yakaita sesarufa nekabhoni dhayokisaidhi uye kuwedzera mashandiro ezvinokonzeresa, kugadzirisa kugadzirwa kwemakemikari nemafuta.

Environmental application

Kugona kwema molecular sieves kushambadza mamorekuru emvura kubva kune zvinwiwa nemagasi anoita kuti ave akakosha mumhando dzakasiyana dzekushandiswa kwezvakatipoteredza.Semuyenzaniso,molecular sievesanoshandiswa mufiriji uye air conditioning masisitimu kuti abvise mvura, nokudaro kudzivirira ngura nechando.

 

Pamusoro pezvo, masefa emamolecular anoshandiswa zvakanyanya se desiccants mukutakura zvinhu kuchengetedza zvigadzirwa zvakaita semishonga uye zvemagetsi zvakaoma.Iyo hygroscopic zvimiro zvema molecular sieves inovimbisa kuchengetedzwa kwemhando uye kuwedzera hupenyu hwesherufu hwezvinhu izvi zvinonetsa.

 

zvekurapa zvikumbiro

Mundima yezvokurapa,molecular sieveskuita basa rakakosha mukuburitsa okisijeni yezvokurapa uye kubvisa kabhoni dhaikisaidhi kubva mumhepo yakabuda mumhepo panguva yekuvhiya.Vanobatsira kubata magasi ekurapa zvakachengeteka uye zvinobudirira, kuvandudza kutarisirwa kwevarwere.

 

mukupedzisa

Muchidimbu, sieve dzema molecular dzine huwandu hwakawanda hwekushandisa uye zvinhu zvakakosha mugasi rechisikigo, petroleum, petrochemical, kuchengetedza kwezvakatipoteredza, zvekurapa uye mamwe maindasitiri.Kugona kwavo kusarudza mamorekuru adsorb zvichienderana nehukuru uye polarity kunoita kuti zvive zvakakosha pamaitiro kubva pakupererwa nemvura uye kucheneswa kusvika pakuparadzaniswa kwemhepo uye zvinokonzeresa maitiro.Sezvo kudiwa kwekuchenesa, matekinoroji anoshanda zvakanyanya ari kuramba achikura, masieve emamorekuru anoramba ari chinhu chakakosha mukushandisa kwakawanda kwemaindasitiri uye kwezvakatipoteredza.
