Phosphoric acid: unsung hero tom qab koj cov piam thaj purity
Thaum koj xav txog phosphoric acid, tej zaum cov dej qab zib lossis chiv tuaj kom lub siab. Tab sis surprise - nws tseem ua si aqab zibLub luag haujlwm hauv kev ua koj cov piam thaj ua kom sov, meej dua, thiab cov khoom ntsuab uas ntsuab! Nyob rau hauv lub qab zib refining refining ntiaj teb, phosphoric acid tsis yog ib tus pab - nws tau xyaum ua cov txawj ua yees siv. Cia peb ntsaub mus rau hauv yuav ua li cas no ntau hom acid ua haujlwm nws cov khawv koob ua haujlwm zoo thiab vim li cas nws tau txais ntau dua li qub.
Dab tsi phosphoric acid ua tau nyob rau hauv qab zib refining?
Tus Tswv Yim Piav Qhia
Nyob rau hauv qab zib mills, phosphoric acid feem ntau ua haujlwm nrog slaked txiv qaub (aka calcium hydroxide). Thaum lawv hnov qab, lawv daim ntawvcalcium phosphate- Ib hom "Hlau nplaum" uas ntxiab thiab tshem tawm cov khib nyiab xws li cov khib nyiab, cov xim, colloids, thiab txawm muaj cov kua txiv hmab me me los ntawm kua txiv qab zib. Qhov tshwm sim? Ib tug ntau huv huv thiab purer phoov.
Los ntawm cov khib nyiab rau kev muaj nyiaj
Nws tsis nres nyob ntawd. Phosphoric acid kuj tseem siv rau hydrolyze thaj chaw bagasse thiab pith (feem ntau muab pov tseg ua liaj ua teb los ntawm cov khoom lag luam) kom rho tawmcov muaj txiaj ntsig zooZoo li D-thylose thiab l-arabinose. Yog lawm - Dab tsi siv los ua cov khib nyiab tuaj yeem ua cov piam thaj ua haujlwm, ntxiv cov khoom siv ntxiv thaum ua cov khoom siv rov ua dua tshiab. Tham txog kev ruaj khov!
Nws muaj ntau yam li cas? Zoo nkauj npaum li cas rau txhua qhov chaw nyob rau hauv qab zib mills
Tshwj xeeb tshaj yog nrov nyob hauv Suav teb
Hauv Suav teb, dhau95% ntawm Canne Qab Zib Ntau LawmSiv cov txheej txheem sulfitation, qhov twg phosphoric acid ua lub luag haujlwm tseem ceeb. Nws ua ke nrog txiv qaub thiab sulfur dioxide rau daim calcium phosphate precoipitates - ib qib tseem ceeb hauv kev lim dej.
Tshiab tech yog nyob rau sawv
Muaj kuj yog ib qho kev ua kom yuam kev tshiab hu uaCua huab cua ua kom huv, qhov twg pa yas tubples nqa calcium phospine phosphate nrog impurities rau saum npoo, ua kom yooj yim rau cov skim yooj yim. Nws tseem yog kev ua tiav rau cov txheej txheem ib txwm, tab sis nyob rau hauv high-purity suab thaj chaw tsim khoom, nws tau pom ntau dua thiab ntau dua.
Perks thiab pitfalls ntawm kev siv phosphoric acid
Qhov zoo:
Super Zoo: Zoo heev thaum tshem tawm impurities li pigments thiab colloids.
Rov dua: Cov phosphate brouprods tuaj yeem siv tau hauv cov txheej txheem.
Muaj peev xwm: Muaj peev xwm ua cov suab thaj ua suab thaj los ntawm biomass.
Cov kev cov nyom:
Nqi & Ib puag ncig: Phosphoric acid tsis yog cov pheej yig tshaj, thiab siv ntau dua tuaj yeem ua tiav kev kho dej.
Precision xav tau: OVERAMING yuav ua rau muaj qab zib poob, yog li cov txheej txheem yuav tsum tau ua kom zoo.
Yuav ua li cas nws ua haujlwm - ib peek tom qab daim ntaub
Chemistry hauv kev nqis tes ua
Yooj yim:
3ca (OH) ₂ {{{{{1} hispo₄ → CA₃ (PO₄) ₂ + 6 h₂o
Qhov calcium phospium phospium phosphate tom qab ntawd ua zoo li daim txhuam cev rau txhua yam ntawm cov khoom uas tsis xav tau hauv koj cov kua txiv.
Huab cua + kua qaub =} huv si phoov
Hauv cov huab cua cua tshuab, microbebles latch on calcium phosphate thiab impurities, nqa lawv mus rau sab saum toj rau kev tshem tawm yooj yim.
Laus tab sis kub: txoj kev ib txwm muaj
Carbonation: Siv cov txiv qaub + co₂ los ua daim ntawv calcium carbonate kom paub meej carbonate kom paub meej carbonate kom paub tseeb.
Phosphoric txheej txheem: Pre-filters the juice, adds phosphoric acid + lime, adjusts pH to 7.0–7.3, then separates out the fluff via floatation.
High-tech Enhancements
Surfactants: Pab ntes cov xim tseem zoo dua.
Kev Ua Tawg Nrauv: Niaj hnub niaj hnub siv lead ua cov txheej txheem ua kom muaj zog ua kom huv ntau dua thiab cov khoom siv.
Cov txiaj ntsig tiag tiag, cuam tshuam tiag tiag
Siab dua: Nrog cov chaw tsim nyog, cua flotation + phosphoric acid tuaj yeem txhawb cov kua puric ntau dua 1 feem pua taw tes.
Vas Siv Tau: Phosphate cov seem tuaj yeem rov qab tau thiab siv rau hauv kev piav qhia, ua cov txheej txheem ob leeg raug nqi thiab muaj txiaj ntsig.
