Nigute Amashanyarazi ya Molecular akora?

molekile ya elegitoronike ni ibintu byoroshye bifite utuntu duto cyane, dufite ubunini bunini.Ikora nk'icyuma cyo mu gikoni, usibye ku gipimo cya molekile, itandukanya imvange ya gaze irimo molekile nini nini.Gusa molekile ntoya kuruta imyenge irashobora kunyuramo;mugihe, molekile nini zirahagaritswe.Niba molekile ushaka gutandukanya nubunini bumwe, icyuma cya molekile nacyo gishobora gutandukana na polarite.Amashanyarazi akoreshwa muburyo butandukanye nkubushuhe bukuraho desiccants kandi bigafasha kwirinda kwangirika kwibicuruzwa.

Ubwoko bwa Molecular

Ibyuma bya molekuline biza muburyo butandukanye nka 3A, 4A, 5A na 13X.Indangagaciro zumubare zisobanura ubunini bwa pore hamwe nubumara bwa shitingi.Ion ya potasiyumu, sodium, na calcium ihindurwa mubigize kugirango igenzure ubunini bwa pore.Hano hari imibare itandukanye ya meshes mumashanyarazi atandukanye.Umuyoboro wa molekuline ufite umubare muto wa meshes ukoreshwa mu gutandukanya imyuka, naho imwe ifite meshes nyinshi ikoreshwa mumazi.Ibindi bipimo byingenzi bya sikile ya molekile harimo ifishi (ifu cyangwa isaro), ubwinshi bwinshi, urwego rwa pH, ubushyuhe bushya (activation), ubushuhe, nibindi.

Molecular Sieve na Silica Gel

Gelika ya Silica irashobora kandi gukoreshwa nkubushuhe bukuraho desiccant ariko buratandukanye cyane nicyuma cya molekile.Ibintu bitandukanye bishobora kwitabwaho muguhitamo hagati yibi byombi ni amahitamo yo guterana, impinduka zumuvuduko, urwego rwubushuhe, imbaraga za mashini, urwego rwubushyuhe, nibindi. Itandukaniro ryingenzi riri hagati ya sikile ya molekile na silika gel ni:

Igipimo cya adsorption ya sikeli ya molekile iruta iya silika gel.Ibi ni ukubera ko icyuma nikintu cyumisha vuba.

Amashanyarazi ya molekile ikora neza kuruta silika gel mubushyuhe bwinshi, kuko ifite imiterere imwe ihuza amazi cyane.

Ubushuhe buke bwa Relative, Ubushobozi bwa sikile ya molekile iruta kure cyane ya silika gel.

Imiterere ya sikeli ya molekile irasobanuwe kandi ifite imyenge imwe, mugihe imiterere ya silika gel ari amorphous na pore nyinshi zidasanzwe.

Uburyo bwo Gukora Amashanyarazi

Kugirango ukoreshe moteri ya molekile, icyifuzo cyibanze ni uguhura nubushyuhe bwo hejuru cyane, kandi ubushyuhe bugomba kuba hejuru bihagije kugirango adsorbate ihumeke.Ubushyuhe bwaba butandukanye nibikoresho byamamajwe n'ubwoko bwa adsorbent.Ubushyuhe buhoraho bwa 170-315oC (338-600oF) byasabwa kubwoko bwa sikeri yavuzwe mbere.Ibikoresho byombi byamamajwe, na adsorbent birashyuha kuri ubu bushyuhe.Kuma Vacuum nuburyo bwihuse bwo kubikora kandi bisaba ubushyuhe buke ugereranije no kumisha umuriro.

Bimaze gukora, amashanyarazi arashobora kubikwa mubirahuri hamwe na parafilm ebyiri zipfunyitse.Ibi bizakomeza gukora kugeza kumezi atandatu.Kugenzura niba amashanyarazi akora, urashobora kuyifata mumaboko mugihe wambaye uturindantoki hanyuma ukongeramo amazi.Niba zikora rwose, noneho ubushyuhe burazamuka cyane, kandi ntushobora kubifata nubwo wambaye uturindantoki.

Gukoresha ibikoresho byumutekano nkibikoresho bya PPE, gants, hamwe nikirahure cyumutekano birasabwa kuko inzira yo gukora amashanyarazi ya molekile ikubiyemo guhangana nubushyuhe bwinshi n’imiti, hamwe ningaruka ziterwa nayo.
