Masero eMolecular anoshanda sei?

Molecular sefa chinhu chine maburi ane maburi madiki, akafanana. Chinoshanda sesefa yekicheni, kunze kwekunge chiri pachikero chemolecular, chinoparadzanisa musanganiswa wegesi une mamorekuru akawanda. Mamorekuru madiki pane mapores chete ndiwo anogona kupfuura nepakati; nepo, mamorekuru makuru akavharika. Kana mamorekuru aunoda kuparadzanisa ari saizi imwechete, molecular sefa inogonawo kupatsanurwa ne polarity. Masefa anoshandiswa mumhando dzakasiyana siyana sekubvisa hunyoro uye anobatsira kudzivirira kuora kwezvigadzirwa.

Mhando dzeMolecular Sies

Masefa eMolecular anouya mumhando dzakasiyana dzakadai se3A, 4A, 5A uye 13X. Nhamba dzinoratidza saizi yepore uye makemikari ari musefa. Maion epotassium, sodium, uye calcium anochinjwa muchimiro kuti adzore saizi yepore. Kune huwandu hwakasiyana hwemasefa mumasefa akasiyana. Masefa eMolecular ane nhamba diki yemasefa anoshandiswa kuparadzanisa magasi, uye rimwe rine masefa akawanda rinoshandiswa kune zvinwiwa. Zvimwe zvikamu zvakakosha zvemasefa eMolecular zvinosanganisira chimiro (hupfu kana bead), huwandu hwakawanda, pH levels, tembiricha yekudzokazve (activation), hunyoro, nezvimwewo.

Molecular Sieve vs. Silica Gel

Silica gel inogona kushandiswawo se desiccant inobvisa hunyoro asi yakasiyana zvikuru ne molecular sefa. Zvinhu zvakasiyana zvinogona kufungwa nezvazvo pakusarudza pakati pezviviri isarudzo dzekuunganidza, shanduko mukumanikidzwa, mwero wehunyoro, simba remakanika, tembiricha, nezvimwewo. Misiyano mikuru pakati pe molecular sefa ne silica gel ndeiyi:

Kuwanda kwekunyudzwa kwesefa yemolecular kwakakura kupfuura kweye silica gel. Izvi zvinodaro nekuti sefa iyi inooma nekukurumidza.

Sefa yemamorekuru inoshanda zviri nani pane silica gel kana tembiricha yakakwira, sezvo iine chimiro chakafanana chinosunga mvura zvakasimba.

Kana hunyoro hwakaderera, kugona kwesefa yemamorekuru kuri nani pane kugona kwesilica gel.

Maumbirwo esipo yemasero anotsanangurwa uye ane maburi akafanana, nepo maumbirwo esilica gel asina chimiro uye akawanda asina kurongeka.

Maitiro Ekuita Kuti Masefu eMolecular Ashande

Kuti ma sefa emolecular ashande, chinhu chikuru chinodiwa ndechekusangana nekupisa kwakanyanya, uye kupisa kunofanira kunge kwakakwira zvakakwana kuti adsorbate iite mhute. Kupisa kunosiyana nezvinhu zviri kunyungudika uye rudzi rwe adsorbent. Tembiricha inogara iripo ye170-315oC (338-600oF) inodiwa kune marudzi ema sefa akambotaurwa. Zvese zviri kunyungudika, uye adsorbent zvinopiswa pakupisa uku. Kuomesa ne vacuum inzira inokurumidza yekuita izvi uye inoda tembiricha yakaderera kana tichienzanisa nekuomesa nemoto.

Kana zvangoshandiswa, masefa anogona kuchengetwa mugirazi rine parafilm yakaputirwa kaviri. Izvi zvichaita kuti arambe achishanda kwemwedzi mitanhatu. Kuti uone kana masefa ari kushanda, unogona kuabata muruoko rwako wakapfeka magirovhosi woawedzera mvura. Kana achishanda zvizere, tembiricha inokwira zvakanyanya, uye hauzokwanisi kuabata kunyangwe wakapfeka magirovhosi.

Kushandiswa kwemidziyo yekuchengetedza yakaita sePPE kits, magirovhosi, uye magirazi ekuchengetedza kunokurudzirwa sezvo nzira yekushanda kwemasefa emamorekuru inosanganisira kubata nekupisa kwakanyanya uye makemikari, pamwe nenjodzi dzakabatana nazvo.
