Mpweya wa carbon molecular

Sieve ya carbon molecular imagwiritsa ntchito sieving yake kuti ikwaniritse kulekanitsa kwa oxygen ndi nitrogen. Gawo lalikulu ndi kaboni wa elemental, wokhala ndi mawonekedwe akuda olimba (m'mimba mwake 1-2mm, kutalika 2-5mm). Chifukwa cha kukhalapo kwa ma micropores ambiri (okhala ndi mainchesi 4 angstroms) okhala ndi kuyanjana kwamphamvu nthawi yomweyo kwa mamolekyu okosijeni, amagwiritsidwa ntchito kulekanitsa mpweya ndi nayitrogeni kuchokera kumlengalenga, kenako kutulutsa nayitrogeni kudzera pa chipangizo cholumikizira mpweya.

Lumikizanani nafe

Mfundo yogwirira ntchito ya sieve ya maselo makamaka imaphatikizapo ntchito ya adsorption ndi sieving ntchito.

Ntchito ya Adsorption: Kutengeka kwa zinthu ndi ma sieve a maselo kumachokera ku kutengeka kwakuthupi, ndipo ma pores awo a kristalo ali ndi polarity yolimba ndi gawo la Coulomb, kuwonetsa kuthekera kwamphamvu kwa mamolekyu a polar (monga madzi) ndi mamolekyu osatulutsidwa. Madzi amadzimadzi akamadutsa mu sieve ya molekyulu, mamolekyu omwe ali mkati amasuntha mosadukiza chifukwa cha mphamvu yokoka ya mamolekyulu ndikugundana ndi pamwamba pa sieve ya mamolekyulu, zomwe zimapangitsa kuti mamolekyu azikhala pamalo okhazikika ndikukwaniritsa kulekana.

Ntchito yowonera: Kugawika kwa pore kwa sieve za ma molekyulu kumakhala kofanana kwambiri, ndipo zinthu zokhazo zomwe zili ndi mainchesi ang'onoang'ono kuposa momwe zimakhalira zimatha kulowa m'matumbo a kristalo a sieve ya maselo. Khalidwe limeneli limathandiza kuti ma sieve a maselo azitha kusiyanitsa ndi kulekanitsa zinthu zosiyanasiyana malinga ndi kukula kwake ndi mawonekedwe ake.

Ntchito ndi Mawonekedwe:

Kuchita bwino kwambiri, kuuma kwakukulu, phulusa lochepa, moyo wautali wautumiki, tinthu tating'onoting'ono, komanso kukana kukhudzidwa kwa mpweya.

Khalidwe lokhazikika: Tsatirani mosamalitsa miyezo yopangira 100% ndikuwongolera kuwunika kwa fakitale poyesa.

Ikhoza kukwaniritsa zofunikira zamitundu yonse ya PSA nitrogen system. M'makampani, CMS imatha kuyika mpweya wa nayitrogeni kuchokera mlengalenga kudzera mu dongosolo la PSA, ndi chiyero mpaka 99.999%.

Masefa a carbon molecular amagwiritsidwa ntchito kwambiri m'mafakitale monga mafuta, mankhwala, migodi ya malasha, kutentha kwazitsulo, kupanga zamagetsi, ndi kusunga chakudya.

PSA nayitrogeni jenereta mpweya nayitrogeni njira kulekana

Mfundo yogwiritsira ntchito kusiyana kwa kuchuluka kwa kufalikira pakati pa mpweya ndi nayitrogeni mu sieve ya carbon molecular sieve ndikuti ma molekyulu a okosijeni amapangidwa mochulukira ndi sieve ya ma molekyulu a kaboni, pomwe mamolekyu a nayitrogeni amalemeretsedwa mu gawo la mpweya kuti akwaniritse kupatukana kwa oxygen.

Kuchuluka kwa ma adsorption a carbon molecular sieves a oxygen kumasiyana kwambiri ndi kukakamizidwa. Kuchepetsa kupanikizika kumatha kuwononga mamolekyu a okosijeni omwe ali mu sieve ya carbon molecular. Bweretsaninso sieve za carbon molecular kuti mukwaniritse kukonzanso mobwerezabwereza kwa carbon molecular sieves.
