Diatomite tsis muaj tshuaj lom thiab tsis muaj teeb meem, thiab nws cov adsorption tsis muaj kev cuam tshuam rau cov khoom xyaw zoo, saj thiab tsw ntawm cov zaub mov. Yog li ntawd, raws li kev pabcuam lim tau zoo thiab ruaj khov, diatomite lim pab tau dav siv hauv kev lag luam khoom noj. Yog li, nws tuaj yeem hais tau tias yog cov khoom noj khoom haus qib diatomite lim pab.
1. Dej haus
1. Carbonated dej haus
Qhov zoo ntawm cov piam thaj dawb ntxiv rau hauv cov txheej txheem tsim cov dej qab zib carbonated plays lub luag haujlwm tseem ceeb hauv qhov zoo ntawm cov khoom tiav. Rau cov kua qab zib dawb uas ua los ntawm vulcanization, diatomite, ua ke nrog cov pa roj carbon ntau ntxiv hauv cov kua dej ua ntej, tuaj yeem tshem tawm feem ntau ntawm cov piam thaj dawb, xws li colloids uas yuav ua rau cov dej haus flocculation thiab ua rau tsis zoo saj, ua rau qeeb ntawm kev lim dej los ntawm kev thaiv cov lim txheej los ntawm cov khoom siv lim dej nyuaj, thiab txo cov nqi ntawm cov xim dawb ntawm lub sij hawm, thiab nce cov nqi ntawm cov xim dawb. qab zib syrup, txhim kho qhov pom tseeb ntawm syrup, thiab thaum kawg ua tau raws li qhov yuav tsum tau ua ntawm cov dej qab zib zoo carbonated.
2. Ntshiab dej haus
Txhawm rau txo cov nag lossis daus thiab flocculent tshwm sim tom qab khaws cov kua txiv hmab txiv ntoo ntshiab, qhov tseem ceeb yog lim thaum lub sijhawm tsim khoom. Hauv kev tsim cov kua txiv hmab txiv ntoo ntshiab, cov kua txiv hmab txiv ntoo yog lim tom qab enzymolysis thiab qhia meej. Muaj ntau yam kev lim dej. Cov kua txiv lim dej los ntawm diatomite muaj feem ntau ntawm cov khoom hauv cov kua txiv hmab txiv ntoo, xws li cov nroj tsuag fibers, denatured colloids / proteins, lim. Nyob rau hauv cov xwm txheej ntawm 6 ° - 8 ° Bx, lub teeb xa tawm tuaj yeem ncav cuag 60% - 70%, qee zaum txawm tias mus txog 97%, thiab cov turbidity qis dua 1.2NTU, txo qhov tshwm sim ntawm nag lossis daus thiab floccules.
3. Oligosaccharides
Raws li cov khoom noj ntxiv qab zib, oligosaccharides muaj qhov zoo ntawm ntau cov khoom carbohydrate vim lawv cov khoom qab zib, kev saib xyuas kev noj qab haus huv, cov khoom noj softening, ua haujlwm yooj yim hauv cov kua hauv lub xeev thiab tus nqi qis. Txawm li cas los xij, hauv cov txheej txheem tsim khoom, ntau cov khoom impurities yuav tsum tau muab tshem tawm, thiab ntau cov proteins yuav tsum tau lim tom qab adsorbed thiab decolored los ntawm cov pa roj carbon activated los ua sediment. Ntawm lawv, activated carbon muaj ob txoj haujlwm: adsorption thiab filtering pab. Txawm hais tias cov txheej txheem decolorization thib ob tau txais yuav, cov nyhuv pom ntawm cov khoom ua tau raws li qhov yuav tsum tau ua, tab sis cov nyhuv adsorption thiab decolorization tsis zoo tagnrho lossis cov nyhuv adsorption thiab decolorization yog qhov zoo tab sis nyuaj rau lim. Lub sijhawm no, diatomite lim pab ntxiv los pab lim. Nyob rau hauv nruab nrab ntawm thawj decolorization pom thiab ion pauv, diatomite thiab activated carbon yog sib koom ua ke los lim, thiab lub teeb transmittance mus txog 99% los ntawm 460nm nrhiav pom. Lub diatomite lim pab daws cov teeb meem saum toj no filtering thiab tshem tawm feem ntau impurities, Tsis tsuas yog cov khoom zoo yog txhim kho, tab sis kuj tus nqi ntawm activated carbon yog txo thiab cov nqi ntau lawm.
