Daim ntawv thov / ntim
Cov khoom no yog siv rau kev sib sib zog nqus ziab ntawm cov roj los yog kua theem ntawm petrochemicals thiab ziab ntawm cov twj paj nruag.
25kg woven hnab / 25kg ntawv board nruas / 200L hlau nruas los yog ib tus neeg thov.
Tus Txheej Txheem Khoom NtawmActivated Alumina
Activated alumina muaj cov yam ntxwv ntawm lub peev xwm loj adsorption, thaj chaw loj tshwj xeeb, lub zog siab, thiab zoo thermal stability. yam khoom. Nws muaj kev sib raug zoo, tsis muaj tshuaj lom, tsis muaj corrosive zoo desiccant, thiab nws muaj peev xwm zoo li qub. Nws yog siv los ua adsorbent, desiccant, catalyst thiab carrier hauv ntau cov txheej txheem tshuaj tiv thaiv xws li roj av, tshuaj chiv thiab tshuaj lom neeg kev lag luam.
Activated alumina yog ib qho ntawm cov khoom siv tshuaj inorganic tshaj plaws hauv ntiaj teb. Cov khoom ntawm activated alumina tau piav qhia hauv qab no: Activated alumina muaj kev ruaj ntseg zoo thiab tsim nyog raws li cov khoom siv desiccant, catalyst carrier, fluorine tshem tawm tus neeg sawv cev, lub siab viav vias adsorbent, tshwj xeeb regeneration agent rau hydrogen peroxide, thiab lwm yam. Activated alumina yog dav siv los ua catalyst thiab catalyst carrier.
Activated alumina yog siv los ua desiccant, feem ntau yog siv rau hauv cov khoom siv cua siab kom qhuav, cov khoom siv cua siab kom qhuav muaj qhov ua haujlwm siab, feem ntau qis dua 0.8Mpa, uas yuav tsum tau ua kom muaj alumina piv kom muaj lub zog zoo txhua yam, yog tias lub zog txhua yam tsawg dhau, nws yooj yim rau hmoov, hmoov thiab dej ua ke yuav ncaj qha thaiv cov khoom siv raj, yog li, ib qho tseem ceeb ntawm kev siv lub zog ntawm cov kav dej, yog li ntawd, ib qho tseem ceeb ntawm kev siv lub zog ntawm cov kav dej. Cov khoom siv, feem ntau yog ob lub tso tsheb hlau luam, ob lub tso tsheb hlau luam ua haujlwm sib hloov, yog qhov ua tau zoo adsorption saturation → analytic voj voog txheej txheem, desiccant yog cov dej adsorption, tab sis nyob rau hauv kev ua haujlwm tiag tiag, cov khoom siv cua tshuab ziab cua yuav muaj roj, xeb thiab lwm yam impurities, Cov khoom no yuav cuam tshuam ncaj qha rau lub neej kev pab cuam ntawm activated alumina adsorption, ntuj adsorption, Adsorption polarity dej kuj zoo heev, tab sis cov roj av alumina adsorption siv cov roj av, sim kom tsis txhob sib cuag nrog roj, xeb, ua haujlwm alumina adsorbent raws li desiccant dav siv lub neej ntawm 1 ~ 3 xyoos, kev siv tiag tiag yuav yog kom qhuav roj dew taw tes los txiav txim seb puas yuav hloov tau alumina. Qhov kub thiab txias ntawm activated alumina yog nyob nruab nrab ntawm 180 ~ 350 ℃. Feem ntau, cov activated alumina ntauwd kub nce mus rau 280 ℃ rau 4 teev. Activated alumina yog siv los ua tus neeg saib xyuas dej, thiab cov tshuaj txhuas sulfate yog siv los ua regenerator. Qhov kev daws teeb meem ntawm aluminium sulfate regenerator yog 2 ~ 3%, lub tshuab txais alumina tom qab adsorption saturation yog muab tso rau hauv aluminium sulfate tov, pov tseg cov tshuaj, ntxuav nrog dej huv 3 ~ 5 zaug. Tom qab siv mus ntev, lub tshuab ua kom alumina nto yog daj xim av thiab cov nyhuv defluorination txo, uas yog tshwm sim los ntawm adsorption ntawm impurities. Nws tuaj yeem kho nrog 3% hydrochloric acid rau 1 zaug thiab rov tsim dua los ntawm txoj kev saum toj no.
