Sodium silicate nroj tsuag: los ntawm kev tsim qauv ua haujlwm

Ib qho kev qhia dav rau kev ua haujlwm zoo

1. Cov txheej txheem ntau lawm

2. Cog qauv kev txiav txim siab

3. Cov tswv yim ua kom tau zoo

4. Kev Ua Lag Luam thiab Kev Lag Luam Tiam

1. Cov txheej txheem ntau lawm
Sodium silicate (dej iav) ntau lawmFeem ntau muab faib ua ob qho txheej txheem loj, uas xav tau xaiv raws li cov yam ntxwv ntawm cov khoom siv raw:

1.1 Cov theem kev tawm tsam ua kua
Cov khoom siv raw: ua kua caustic dej qab zib (Naoh), Quartz xuab zeb (sitena) thiab dej yog rhaub rau {{0} degree rau cov tshuaj tiv thaiv.
Module Control: Los hloov kho cov suab paj nruag / Na₂o Molar piv (feem ntau 2. {}}. 7), cov khoom lag luam nrog cov qauv sib txawv yog tsim tawm.
Yuav tsum tau siv cov khoom siv: Alkali Corrosion-resistant reactor, tsis siv neeg kho qhov kub thiab txias tswj.
1.2 Khoom Theem Thermal
Kev kub siab compination txoj kev: soda tshauv (na ₂₂₂₃) lossis sorium sandfate (nautz xuab zeb tau siv thiab quarted ntawm 1350-1450 degree hauv cov reverberatory rauv.
Kev Txawj Mob Ib puag ncig: Kev tso pa tawm (xws li ntaus ntawv ua kom rov qab) yuav tsum tau ua kom tau raws li cov qauv emission.
2. Cog qauv kev txiav txim siab
2.1 txoj kev xaiv txoj kev xaiv
Kev ntsuas kev lag luam: Cov qauv theem tau muaj peev txheej peev txheej (txog $ 2 lab / 50, tab sis kev siv hluav taws xob ntau; Cov theem theem yog tsim nyog rau kev tsim khoom loj txuas ntxiv.
Cov khoom siv raw hloov kho: Asia tshuaj pom zoo: Quartz xuab zeb purity yuav tsum yog> 98%, particle loj {1}} mesh.

Thawj txheej txheem yog cov txheej txheem qhuav. Thaum lub purity ntawm quartz xuab zeb nyob rau hauv cov khoom siv raw yog siab, thiab cov particle li cas, sodium carbonate) yog ruaj khov carbonate) yog ruaj khov, cov txheej txheem qhuav yog qhov kev xaiv tsim nyog dua. Hauv kev tsim khoom qhuav, cov xaiv quartz xuab zeb thiab dej tshauv yog thawj tov nyob rau hauv ib qho kev faib ua feem, tag nrho cov kev sib xyaw, thiab tom qab ntawd muab tso rau hauv lub cub tawg. Nyob rau hauv lub cub tawg, qhov kub feem ntau mus txog txog 1300 kawm tiav 1400 degree. Nyob rau hauv cov kub siab no, quartz xuab zeb (lub ntsiab sib xyaw silicon dioxide) reacts chemically nrog dej qab zib ua cov sodium silicate. Hauv cov txheej txheem no, muaj cov nruj me ntsis tswj xws li cov cua sov kev tswj hwm thiab cov tshuaj tiv thaiv kev ua kom paub tseeb thiab ua kom zoo nkauj sodium silicate melt. Tom qab generated sodium silicate blows tawm ntawm cov cub tawg, nws undergoes tom qab txias xws li cua txias thiab thaum kawg tau txais cov khoom siv sidium silicate.

Qhov txheej txheem thib ob yog txheej txheem ntub. Thaum lub quartz xuab zeb nyob rau hauv cov khoom siv raw yog finer nyob rau hauv particle loj thiab muaj qee qhov kev thov loj rau cov kua silium silicate, cov txheej txheem ntub yog qhov haum ntau. Hauv kev ntub dej, Quartz xuab zeb yuav tsum ua ntej ua ntej kom tshem tawm impurities thiab txhim kho nws cov kev coj dawb huv. Tom qab ntawd kho cov xuab zeb quartz xuab zeb thiab caustic dej qab zib (sodium hydroxide) muaj ntxiv rau cov tshuaj reactor hauv cov proportion. Nyob rau hauv lub reactor, los ntawm cua sov thiab nplawm, quartz xuab zeb thiab feem ntau ntawm 100 degree) thiab siab mob los tsim cov sodium silicate kua. Thaum lub sij hawm cov txheej txheem kev tshuaj tiv thaiv, cov tshuaj tiv thaiv kub, lub siab lub sijhawm yuav tsum tau them rau kev sib tsoo ntawm kev ua kom nruj ntawm cov tshuaj tiv thaiv. Tom qab cov tshuaj tiv thaiv tau ua tiav, siv tsis tau impurities thiab cov khoom siv tau tshem tawm los ntawm kev ua haujlwm thiab lwm yam kev ua haujlwm kom tau txais cov kua ntshiab sidium silicate. Yog tias cov khoom siv sodium site yuav tsum tau tsim tawm, cov kua sodium silicate tuaj yeem raug rau cov kauj ruam kev kho mob tom ntej xws li concentration thiab crystallization.

2. Cog qauv kev txiav txim siab

Ntsuam xyuas nyiaj txiag:

Hauv kev tsim cov sodium silicate silicate (dej iav), kev xaiv ntawm txheej txheem txoj kev muaj kev cuam tshuam tseem ceeb rau tus nqi thiab ntau lawm. Raws li cov txheej txheem ntau lawm, ib qho ntawm cov nqi uas tseem ceeb ntawm cov txheej txheem theem ua kua yog tias cov peev txheej peev yog tsawg. Noj cov peev xwm ntau lawm ntawm 50, 000}} Tus qauv ua piv txwv, cov peev txheej peev nyiaj tsuas yog li 2 lab daus las. Qhov no zoo nkauj heev rau qee cov tuam txhab uas muaj nyiaj tsawg lossis uas xav nkag mus rau tom khw ntawm tus nqi qis hauv tus nqi thaum ntxov. Txawm li cas los xij, cov theem ua kua kuj tseem muaj qee qhov tsis zoo, qhov ntawd yog, kev siv hluav taws xob ntau. Hauv cov txheej txheem ntau lawm, vim tias yuav tsum tau tswj cov kab mob theem ua kua, ua cua sov, uas yuav tau ua kom tau tus nqi tsim khoom, uas yuav ua rau muaj nqi ntau lawm Nrog rau kev hloov pauv txuas ntxiv ntawm cov nqi zog, kev siv zog siv cov txheej txheem theem ua kua yuav muaj kev cuam tshuam ntau dua rau kev lag luam muaj txiaj ntsig.

Cov theem theem teeb yog qhov tsim nyog rau kev tsim khoom loj txuas ntxiv. Txawm hais tias cov khoom siv peev ntawm txoj kev theem khoom yog qhov tseem ceeb, nws cov khoom siv ntau lawm yog ntau ntau. Xws li cov txheej txheem loj-teev ntau, cov txheej txheem theem khoom tuaj yeem muab tag nrho cov kev ua si tas li, txo lub sijhawm nyob hauv cov txheej txheem ntau lawm, thiab yog li nce cov zis rau ib teev sijhawm. Ntxiv rau, cov txheej txheem theem khoom tuaj yeem tswj cov khoom zoo dua thiab txo cov khoom tsis xws luag thaum muaj kev ruaj ntseg thiab txuas ntxiv ntawm cov txheej txheem ntau lawm. Hauv lub sijhawm ntev, nws yuav pab txhim kho kev ua lag luam kev sib tw thiab cov nyiaj txiag ntawm cov lag luam.

Cov Khoom Siv Raw Khoom Noj Khoom Siv:

Raws li lub koom haum tshaj lij hauv kev lag luam, Asia tshuaj muaj qhov tob hauv kev tshawb nrhiav thiab kev paub txog ntawm cov khoom siv raw rau sodium silicate ntau lawm. Lub tuam txhab qhia kom pom tias lub purity thiab particle loj ntawm quartz xuab zeb yog ob qhov tseem ceeb thaum xaiv cov txheej txheem ntau lawm.

Rau kev ua kom huv ntawm Quartz xuab zeb, nws cov ntsiab lus yuav tsum muaj ntau dua 98%. Kev ua kom huv si quartz xuab zeb tuaj yeem txo cov impurities nyob rau hauv cov txheej txheem ntau lawm, ua kom cov tshuaj tiv thaiv ntau lawm, thiab yog li txhim kho qhov zoo ntawm cov khoom. Yog hais tias lub impurity cov ntsiab lus nyob rau hauv quartz xuab zeb dhau lawm, nws yuav hnov ​​nrog cov sodium silicate, thiab txawm ua rau cov khoom lag luam zoo tsis kam, uas tsis tuaj yeem ua tiav kev thov lag luam.

Cov cawv ntawm Quartz Sand Partle ntawm Sodium Silicate ntau lawm

Nyob rau hauv cov nqe lus ntawm particle loj, lub particle loj ntawm quartz xuab zeb yuav tsum tau tswj nruab nrab 40-120 mesh. Qhov tsim nyog ua kom tsim nyog muaj peev xwm loj tuaj yeem ua kom muaj thaj chaw tiv tauj thiab cov tshuaj tiv thaiv ntawm Quartz xuab zeb hauv cov tshuaj tiv thaiv. Yog tias qhov loj me me loj dua, thaj chaw tiv toj ntawm cov ntaub ntawv quartz thiab lwm cov khoom nyoos yuav tsis tiav, thiab cov tshuaj tiv thaiv yuav tsis tiav, ua rau txo qis kev ua haujlwm; Yog hais tias lub particle loj me me me me heev, nws yuav nce kev tawm tsam thaum cov tshuaj tiv thaiv, thiab tseem yuav nce qhov nyuaj ntawm kev sib cais txuas ntxiv thiab ua tiav.
