Sesiphi esona sihluzo se-hoodless fume hood?

Kwisixhobo sokungenisa umoya esingenamibhobho (Ukuqhuba I-Fume Hood, iKhabhinethi yoGcino oluHluliweyo, PCR Workstations, I-Laminar Flow Hoods, iiKhabhinethi zeBiosafety njl), isihluzi ngokungathandabuzekiyo sesona sigaba sibalulekileyo. Xa kufikwa ekususweni kweegesi zekhemikhali, izihluzi zekhabhoni ezisebenzayo zineyona mpumelelo iphezulu kwaye ibe lukhetho lokuqala lwezixhobo ezahlukeneyo ezinxulumeneyo, siya kukuxelela ukuba yiyiphi ikhabhoni esebenzayo kunye nendlela izihluzi zethu ezizezona zilungileyo.

Yintoni iActiated carbon?

Kudala kwafunyaniswa ukuba zombini iiminerali carbon (amalahle, ithambo lekhabhoni, njl.njl.) okanye ikhabhoni yesityalo (ilahle, iqokobhe lekhokhonathi ikhabhoni, njl. njl.) kunye nekhabhoni yemichiza (icoke, icarbon emnyama, njl. njl.), zonke zinegesi ethile. amandla e-adsorption. Ingakumbi iCarbon enemingxuma engaphezulu kumphezulu wayo inokutsala iigesi ezininzi zekhemikhali.

Inani elikhulu le-micropores lenziwa phezu kwezinto zekhabhoni ngeendlela zenyama okanye zekhemikhali ezifana nokutsha kunye nokutshisa okutshisayo. Ezi micropores zandisa ngempumelelo indawo yangaphakathi efunwa yikhemikhali adsorption. Ummandla wangaphakathi we-1 kg ye-carbon activated inokufikelela kwi-1 km2!

Ubume bomphezulu bekhabhoni esebenzayo phambi (ekhohlo) nasemva (ekunene) kusebenze phantsi kwemakroskopu

Inani kunye nokwakheka kwee-micropores kumphezulu wekhabhoni esebenzayo eyenziwe kwizinto ezahlukeneyo zekhabhoni nazo zahlukile. Kwiintlobo ngeentlobo zekhabhoni esebenzayo, ezo zicutshungulwa kwikhabhoni yesityalo zinesakhiwo esininzi se-microporous, phakathi kwayo iqokobhe lekhokhonathi ikhabhoni yeyona ilungileyo.

Iqokobhe leKhokhonathi kunye neqokobhe leKhokhonathi esetyenzisiweyo

Isebenza njani i-carbon adsorb?

Kumphezulu wekhabhoni esebenzayo kukho iimicropores ezininzi, xa irhasi ingena emingxunyeni, iimolekyuli ezinkulu okanye iikhompawundi zesakhiwo esinzima ziya kubanjwa kwaye zigcinwe ngokuzinzileyo apho. Nangona kunjalo, kwezinye iikhompawundi eziphilayo ezinobunzima obuphantsi be-molecular , (ezifana ne-formaldehyde), iigesi ze-inorganic (ezifana ne-HNO3, i-H2SO4, i-HCl, njl.), i-ammonia (NH3) kunye ne-amine compounds, i-carbon activated ecocekileyo ayikwazi ukwenza kakuhle.

Kutheni le nto isihluzo sethu sekhabhoni esenziwe sasebenza sesona silungileyo?

Ikhabhoni yethu esetyenzisiweyo ifakwe kwizongezo zekhemikhali ezikhethekileyo, ezi zingcoliseko ezingafunxayo zikhankanywe ngasentla ziya kuvelisa ukusabela kweekhemikhali kunye nezongezo eziqhotyoshelwe kwi-microporous ye-carbon activated, kwaye ekugqibeleni zenze izinto ezinokubhengezwa.

Uninzi lwezihluzi zivelisa ngokulula iikhabhoni kwibhokisi, ezikhokelela kwiingxaki ezintathu, ukuvuza kwekhabhoni, ukusasazwa okungalinganiyo, kunye nesiphene esingaphantsi kokuhamba komoya okuqhubekayo.

Xunling Itekhnoloji yesigaba segesi iqokobhe lekhokhonathi izihluzi zekhabhoni zisebenzisa imidiya yethu ekhethekileyo yokuhluza ikhabhoni. Oku kunciphisa uthuli lwekhabhoni olunokuba yingozi olufumaneka kwizihluzi zekhabhoni zegranular. Inkqubo yethu yobunini bokubambisana ibamba ikhabhoni kwi-matrix eqikelelwayo, ukuthintela ukutshintshwa kwekhabhoni okungakhokelela "kwiendawo ezifileyo" eziqhelekileyo kwizihluzi zegranular zemveli.
