Lub hauv paus rau phau ntawv
Nyob rau hauv lub ntiaj teb muaj yeeb yuj, xim yog zoo li muaj lub zog zoo nkauj, ntxiv hnub ci ntsa iab tsis muaj hnub ci thiab ntxim nyiam rau peb lub neej. Los ntawm cov tsev zoo kawg rau cov tsev muaj txiaj ntsig, los ntawm cov cuab yeej muaj cov khoom lag luam qib siab rau txhua qhov chaw thiab ntsiag to ua lub luag haujlwm tseem ceeb. Txawm li cas los xij, hauv cov txheej txheem ntawm kev siv cov xim, teeb meem uas feem ntau cov teeb meem nyob ntsiag to, qhov ntawd yog, nag lossis daus thiab ua kom tsis txhob ua nag.
1. Cov tsos ntawm nag lossis daus thiab cem
- Nyob rau hauv lub ntiaj teb ntawm cov txheej xwm, nag lossis daus thiab agglomeration yog zoo li cov qhua tsis muaj tseeb, feem ntau ua rau cov teeb meem rau cov neeg siv tsis ua haujlwm. Lawv tsis yog tsuas cuam tshuam rau cov tsos ntawm cov txheej, tab sis kuj tseem muaj ntau yam kev tsis zoo ntawm nws cov nyhuv thiab kev tsim kho.
- Nas nag teeb meem feem ntau yog hais txog qhov tshwm sim uas cov khoom muaj nyob hauv cov xim maj mam tog vim yog kev ua ntawm lub ntiajteb txawj nqus thiab sib sau rau hauv qab ntawm lub sijhawm cia lossis siv. Cov khoom muaj me me no yuav yog pigments, fillers, lossis lwm yam additives. Caking yog hais txog cov lus hauv cov xim sib raug zoo ua ke los ua ib lub pob loj dua. Cov degree ntawm Cakaking tuaj yeem sib txawv ntawm ib qho me me mos mos mos rau lub pob tawv.
- Thaum peb qhib lub thoob ntawm cov xim pleev xim uas tau khaws cia rau qee lub sijhawm, peb feem ntau pom ib qho tuab txheej ntawm hauv qab, lossis pom qee lub clumps ntawm kev sib txawv ntawm cov xim. Cov kev tso nyiaj no thiab pob tsuas tsis tsuas yog cuam tshuam rau cov tsos ntawm cov xim, ua rau nws saib tsis ncaj thiab tsis zoo, tab sis kuj tuaj yeem muaj kev cuam tshuam loj rau kev ua yeeb yam ntawm cov xim.
2, qhov kev cuam tshuam tsis zoo ntawm nag lossis daus thiab cem
- Ua ntej tshaj plaws, nag lossis daus thiab kev poob siab yuav cuam tshuam kev tsim kho cov xim. Yog tias muaj ntau qhov kev ua kom loj yog nyob rau hauv cov xim, thaum lub sij hawm tsim kho, cov kev tsim kho no yuav txhaws cov phom txaws, txhuam lossis cov khoom siv nyuaj. Tsis tas li ntawd, muaj cov sediment yuav tseem ua kom lub fluiment ntawm cov txheej tsis zoo, nyuaj rau tusyees kis rau ntawm cov khoom siv coated, yog li cuam tshuam qhov zoo ntawm txheej. Rau caked txheej, qhov xwm txheej yog qhov hnyav dua. Cov xim caked yog qhov nyuaj rau kom tau do tusyees, nws yog NW nyuam qhuav tsim tej yam tsis xws luag nyob rau hauv qhov txheej, xws li pob, kab nrib pleb thiab lwm yam.
- Thib ob, daus thiab kev poob siab yuav txo cov kev ua tau zoo ntawm cov xim. Pigments thiab fillers nyob rau hauv cov txheej txheej yog qhov tseem ceeb hauv kev txiav txim siab lawv ua tau zoo. Yog tias cov khoom no precipitate lossis ua kom tsis txhob faib cov pigments thiab fillers nyob rau hauv cov xim, uas yuav cuam tshuam rau txheej txheej, xim ruaj khov thiab lwm yam khoom. Piv txwv li, tso cov xim pigments yuav ua rau cov xim ntawm txheej sib dua lossis tsis sib xws, thaum Caked Fillers tuaj yeem txo cov zog ntawm cov txheej.
- Tsis tas li ntawd, nag lossis daus thiab kev poob siab kuj yuav muaj kev cuam tshuam rau kev ruaj ntseg ntawm cov xim. Yog tias cov xim tau nquag nquag ua haujlwm thiab ua kom tiav thaum lub sijhawm cia, nws yuav ua rau lub neej ua kom luv ntawm cov xim pleev xim thiab nce cov pov tseg ntawm cov xim. Nyob rau tib lub sijhawm, nquag muaj kev ntxhov siab thiab kev kho mob ntawm nag lossis agglomeration yuav ua rau cov neeg siv haujlwm ua haujlwm thiab raug nqi.
3. Kev tshuaj xyuas ntawm cov ua rau muaj nag lossis daus thiab ua
- Ua ntej, cov khoom ntawm cov pigments thiab fitters yog ib qho ntawm cov tseem ceeb uas ua rau nag lossis daus. Cov xim sib txawv thiab cov fitters muaj cov qauv sib txawv, qhov ntau thiab tsawg. Feem ntau, cov lus nrog cov ntom ntom dua thiab loj dua qhov loj me me muaj ntau dua nag los. Ib qho ntxiv, cov khoom ntawm qee cov pigments thiab fillers tseem cuam tshuam rau lawv cov kev ruaj khov nyob rau hauv cov txheej txheem. Piv txwv li, hais nrog hydrophilic nto moo nqus dej, uas ua rau muaj nag lossis daus thiab ua kom tsis txhob ua.
- Qhov thib ob, cov tsim ntawm cov txheej tseem muaj qhov cuam tshuam tseem ceeb rau nag lossis daus thiab ua kom tsis txhob ua. Cov qauv ntawm txheej ci ntsa iab nrog cov resins, cov kuab tshuaj, pigments, fillers thiab ntau yam auxilies. Yog tias qhov sib raug zoo ntawm cov cob muaj nyob rau hauv cov mis nrog cov xim thiab cov tub lim tawm tsis zoo, nws yuav ua rau muaj kev sib txawv, thiab nws yooj yim rau precipitate thiab cem. Piv txwv li, qee cov khoom siv yuav flocculate hauv cov kuab tshuaj uas muaj tseeb, ua rau muaj nag lossis daus ntawm cov pigments thiab fillers. Tsis tas li ntawd, cov feem sib piv ntawm cov xim los ua haujlwm cob thiab tus nqi ntawm cov tub lim mam yuav tseem cuam tshuam rau kev ruaj ntseg ntawm txheej. Yog tias cov pigments thiab sau ntau dhau, ntau dua li nqa lub peev xwm ntawm lub resin, nws yooj yim rau precoipitate thiab cemaking.
- Ib qho ntxiv, cov neeg tuaj yeem tseem ceeb kuj cuam tshuam txog cov txheej los nag thiab kev ua tsis taus. Cov xim yuav tsum muab cia rau hauv qhov chaw qhuav, txias thiab muaj cua zoo. Yog tias qhov ntsuas kub ntawm qhov chaw cia khoom yog qhov siab dhau, cov xim av siab dhau, nws yuav ua rau cov xim pleev xim kom haum, nws yuav ua rau cov dej num tsis txaus, uas yuav ua rau nag lossis daus thiab agglomeration. Piv txwv li, nyob rau hauv ib puag ncig kub thiab vaum nyob rau hauv cov xim yog yooj yim heev dawb huv ntawm cov xim, uas ua rau cov xim thiab muab tub lim kom precipitate. Nyob rau tib lub sijhawm, kev nkag mus hauv dej kuj tseem yuav ua rau qee cov pigments thiab fillers kom yauv ua cov tshuaj tiv thaiv hydrolysis thiab ua nag lossis daus.
- Ntxiv rau, cov txheej txheem ntau lawm thiab sib xyaw ua ke ntawm cov txheej yuav muaj kev cuam tshuam rau nag lossis daus. Yog tias cov pigments thiab fillers tsis txaus ua tsis txaus thaum lub sijhawm cov txheej txheem ntau lawm, lossis kev sib xyaw tsis zoo, nws yuav ua rau muaj kev sib xyaw ua ke, nws yuav ua rau muaj kev sib sau ua ke thiab cov ntawv ua ntej thiab cov koog tas. Ib qho ntxiv, thaum lub sijhawm kev thauj mus los thiab khaws cov xim pleev xim, yog tias nws yog kev ntxhov siab, nws kuj tseem tuaj yeem ua rau cov xim ruaj khov, ua rau nag lossis daus.
4, tshawb nrhiav txoj hauv kev zoo tshaj plaws los daws cov nag lossis daus thiab ua tsis taus
- Ua ntej, pib nrog kev xaiv ntawm pigments thiab fillers. Thaum xaiv cov pigments thiab fillers, hais nrog nrawm nrawm, me me particle loj thiab cov duab ib txwm yuav tsum tau xaiv kom deb li sai tau. Nyob rau tib lub sijhawm, them sai sai rau cov khoom saum npoo ntawm cov pigments thiab fillers, thiab xaiv cov khoom uas muaj kev sib raug zoo nrog cov khaub ncaws zoo. Piv txwv li, cov pigments thiab fillers uas tau raug kho rau saum npoo muaj peev xwm xaiv tau los txhim kho lawv cov kev tsis txaus siab thiab ruaj khov nyob rau hauv cov txheej txheem.
- Qhov thib ob, cov tsim ntawm txheej yog qhov zoo. Nyob rau hauv kev tsim qauv tsim qauv, kev sib cuam tshuam ntawm cov resins, cov kuab tshuaj, fillers, fillers thiab cov ntaub ntawv tsim nyog thiab cov lus sib piv yuav tsum tau xaiv. Piv txwv li, koj tuaj yeem xaiv lub resin nrog zoo sib xws nrog cov pigments thiab fillers, kho cov pigments thiab resins, thiab tswj tus nqi ntawm fillers. Tsis tas li ntawd, qee cov tshuaj ntxiv xws li cov neeg sawv cev los tiv thaiv kev tiv thaiv thiab cov disperstants tseem tuaj yeem muab ntxiv rau kev ruaj ntseg ntawm cov xim.
- Tsis tas li ntawd, cov neeg muaj kev cia yog tswj hwm nruj me ntsis. Cov xim yuav tsum muab cia rau hauv qhov chaw qhuav, txias, tsis muaj cua zoo, tsis txhob muaj hnub ci thiab huab cua sov thiab av noo. Nyob rau tib lub sijhawm, xyuas kom meej tias cov xim pleev xim yog ntim tau zoo los tiv thaiv kev nkag mus ntawm noo noo thiab impurities. Thaum lub sijhawm cia, cov xim kuj tseem tuaj yeem ua kom tsis tu ncua los tiv thaiv nag lossis daus thiab ua kom tsis txhob ua.
- Ib qho ntxiv, nws tseem yog ib qho tseem ceeb heev los txhim kho cov txheej txheem ntau lawm thiab cov txheej txheem sib xyaw. Hauv cov txheej txheem ntau lawm, cov cuab yeej dispersion ua kom meej thiab cov txheej txheem yuav tsum tau siv los xyuas kom meej tias cov pigments thiab fillers tau tawg tag nrho. Nyob rau tib lub sijhawm, them sai sai rau lub nrawm thiab lub sijhawm ntawm kev sib xyaw kom tsis txhob sib xyaw ntau dhau los lossis sib xyaw tsis ncaj. Hauv kev thauj mus los thiab cov txheej txheem cia ntawm cov xim tha xim, nws tseem tsim nyog kom zam dhau kev ua txhaum kev cai thiab kev ntxhov siab.
Rau txheej txheej uas tau precipitated thiab caked, peb tuaj yeem nqa qee qhov kev ntsuas los cuam tshuam nrog nws. Yog tias cov nag lossis daus yog lub teeb, cov sediment tuaj yeem rov tawg rau hauv cov xim los ntawm nplawm. Thaum sib xyaw, koj tuaj yeem siv cov khoom siv neeg kho tshuab lossis phau ntawv sib xyaw ua ke kom ntseeg tau tias cov kev sib xyaw yog cov khoom sib xyaw. Yog tias cov dej nag yog qhov hnyav dua, koj tuaj yeem txiav txim siab ntxiv qee qhov tsis txaus ntseeg lossis ua rau tsis muaj txiaj ntsig los pab cov txhauv tawg. Rau caked xim, koj tuaj yeem ua ntej tsoo lub caked, thiab ces do. Yog hais tias cov koog ntoo nyuaj dhau lawm, cov xim yuav yog siv tsis tau thiab xav tau kom raug kaw.
8. Cov ntsiab lus thiab cov lus qhia
Hauv ntej, nag lossis daus thiab ua kom pom tseeb rau hauv cov teeb meem yog qhov nyuaj uas xav tau kev txiav txim siab thiab kev daws teeb meem los ntawm ntau yam. Los ntawm kev xaiv cov xim uas tsim nyog thiab muab cov fillers, ua kom zoo rau txheej txheej thiab kev sib xyaw ua ke thiab kev ua kom zoo thiab ruaj khov thiab ruaj khov thiab muaj peev xwm txhim kho tuaj yeem hloov kho. Nyob rau tib lub sijhawm, rau txheej uas muaj precipitated thiab caked, peb kuj tseem tuaj yeem coj txoj kev kho kom tsim nyog los rov ua tau cov txheej txheem ntawm cov txheej kom ntau li ntau tau.
Nyob rau hauv yav tom ntej kev tshawb fawb thiab kev tsim kho cov txheej txheem, peb yuav tsum tau them nyiaj ntau dua rau cov teeb meem tshiab thiab niaj hnub los daws cov teeb meem xws li dej nag lossis daus thiab ua kom dej nag. Nyob rau tib lub sijhawm, cov neeg ua haujlwm thiab cov neeg siv ntawm kev ua xim pleev xim yuav tsum tau ntxiv dag zog thiab siv cov xim muaj tseeb, kom tsis txhob muaj cov teeb meem xws li nag lossis daus.
