Isiphi isihlungi esingcono kakhulu se-ductless fume hood?

Emishinini yokungenisa umoya engenamapayipi (Ingenawo amapayipi I-Fume Hood, Ikhabhinethi Yesitoreji Esihlungiwe, I-PCR Workstations, I-Laminar Flow Hoods, amaKhabhinethi e-Biosafety njll), isihlungi ngokungangabazeki siyingxenye eyinhloko ebaluleke kakhulu. Uma kuziwa ekukhishweni kwamagesi amakhemikhali, izihlungi zekhabhoni ezicushiwe zisebenza kahle kakhulu futhi ziba ukukhetha kokuqala kwemishini ehlukahlukene ehlobene, sizokutshela ukuthi yini i-Actiated carbon nokuthi izihlungi zethu zingcono kakhulu.

Iyini ikhabhoni esebenzayo?

Sekuyisikhathi eside kwatholakala ukuthi kokubili i-carbon mineral (amalahle, i-bone carbon, njll.) noma i-carbon carbon (amalahle, igobolondo likakhukhunathi ikhabhoni, njll.) kanye nekhemikhali ye-carbon (i-coke, i-carbon black, njll.), konke kunegesi ethile. umthamo we-adsorption. Ikakhulukazi Ikhabhoni enezimbotshana eziningi ebusweni bayo ingaheha amagesi amakhemikhali amaningi.

Inani elikhulu lama-micropores akhiwa ebusweni bezinto zekhabhoni ngezindlela ezingokoqobo noma zamakhemikhali njengokushiswa okuyingxenye kanye nokushisa okushisayo. Lawa ma-micropores akhulisa ngempumelelo indawo yangaphakathi edingwa ukukhangiswa kwamakhemikhali. Indawo yangaphakathi ye-1 kg yekhabhoni ecushiwe ingafinyelela ku-1 km2!

Isakhiwo esingaphezulu sekhabhoni ecushiwe ngaphambi (kwesobunxele) nangemuva (kwesokudla) kokwenza kusebenze ngaphansi kwesibonakhulu

Inombolo nokwakheka kwama-micropores ebusweni bekhabhoni ecushiwe eyenziwe ngezinto ezihlukene zekhabhoni nakho kuhlukile. Ezinhlobonhlobo zekhabhoni ecushiwe, lezo ezicutshungulwa kukhabhoni yezitshalo zinesakhiwo esiningi kakhulu se-microporous, phakathi kwayo igobolondo likakhukhunathi ikhabhoni ehamba phambili.

Igobolondo likakhukhunathi kanye negobolondo likakhukhunathi elicutshunguliwe lekhabhoni ecushiwe

Isebenza kanjani i-carbon adsorb?

Phezu kwekhabhoni ecushiwe kukhona ama-micropores amaningi, lapho igesi ingena emigodini, ama-molecule amakhulu noma izinhlanganisela zesakhiwo esiyinkimbinkimbi zizobanjwa futhi zigcinwe ziqinile lapho. Kodwa-ke, kwezinye izinhlanganisela eziphilayo zesisindo esiphansi samangqamuzana , (njenge-formaldehyde), amagesi angaphili (njenge-HNO3, H2SO4, HCl, njll.), i-ammonia (NH3) nama-amine compounds, ikhabhoni ehlanzekile ecushiwe ayikwazi ukwenza kahle.

Kungani isihlungi sethu sekhabhoni esicushiwe singcono kakhulu?

Ikhabhoni yethu ecushiwe icwiliswe izithasiselo zamakhemikhali ezikhethekile, lokhu kungcola okungamuncwa okukhulunywe ngenhla kuzoveza ukusabela kwamakhemikhali nezithasiselo ezinamathiselwe ku-microporous of activated carbon, futhi ekugcineni kwakheka izinto ezingakhangiswa.

Izihlungi eziningi ezikhiqizayo zivele zivale amakhabhoni ebhokisini, okuholela ezinkingeni ezintathu, ukuvuza kwekhabhoni, ukusatshalaliswa okungalingani, kanye nesici esidlulele ngaphansi komthelela oqhubekayo wokugeleza komoya.

Xunling Izihlungi zekhabhoni zegobolondo legesi le-Technologies zisebenzisa imidiya yethu eyingqayizivele eboshiwe yokuhlunga ikhabhoni. Lokhu kunciphisa uthuli lwekhabhoni olungaba yingozi olutholakala kuzihlungi zekhabhoni eziyimbudumbudu. Inqubo yethu yobunikazi bobunikazi ibamba ikhabhoni ku-matrix ebikezelwayo, ivimbele ukushintsha kwekhabhoni okungaholela "ezindawo ezifile" ezivamile kuzihlungi zendabuko eziyimbudumbudu.
