Cov roj reducer ntau npaum li cas yuav tsum tau siv ib lub mev ntawm pob zeb ua?

Feem ntau, txo cov ntsiab lus dej los ntawm 1 nkas loos ib cubic mev ntawm lub zog tuaj yeem nce ntxiv txog 250 psi, vim muaj kev txhim kho dej nkag mus rau cov xis mas.

Thawj zaug dej Reducers yog cov neeg sawv cev ib txwm muaj, xws li sodium lignosulfonate. Qhov kev pom zoo tau muab tshuaj feem ntau yog 0. 3%}. 3%}. 3%}. {}}}%. Cov no yog tus nqi-ua tau zoo thiab feem ntau siv nrog superplasticizers. Txawm li cas los xij, cov tshuaj yuav sib txawv raws li qhov uas xav tau ua haujlwm zoo ib yam li cov haujlwm uas xav tau, kev mob ib puag ncig, thiab ib qho kev lees paub ntxiv. Txhawm rau laij cov nqi yees, koj yuav xav tau qhov hnyav ntawm cov cement hauv kev sib tov thiab muab nws txuas ntxiv los ntawm feem pua ​​pom zoo.

Rau cov tshuaj zoo saib xyuas, ib txwm xa mus rau cov chaw tsim khoom cov lus qhia lossis sab laj nrog cov kws tshaj lij pob zeb. Txog kev nug, koj tuaj yeem ncav tes rau peb ntawm cz@cqbrd.com.

Tom qab ntawd, cov dej tsoos tso pa roj hloov hloov mus rau hauv cov qauv zoo, nrog Naphthalene Formensehyde condensates (SNF) lossis Naphthalene based ua kom dav. These typically have a recommended dosage of 0.5-1%, reducing water content by 15-25% or even more.

Naphthalene superplasticizer vs. sodium lignosulfonate

Ob leeg Naphthalene SuperPlasticizer thiab sodium Lignosulfonate feem ntau siv cov dej reducers, tab sis lawv txawv hauv ob peb yam tseem ceeb:

1.chemical composition:

• Naphthalene Superplasticizer:Muab tau los ntawm naphthalene, cov khoom siv hydrocarbon, cov khoom lag luam no yog cov lus qhia los ntawm kev ua kom zoo nkauj ntawm nochthalene sulfonic acid nrog formaldehyde.
• Sodium Lignosulfonate:Qhov no yog breproducter ntawm purp thiab daim ntawv kev lag luam, tau los ntawm Sulfonating Lignin, lub ntuj muaj zog pom hauv cov ntoo thiab nroj tsuag.

2.Txoj kev txo cov khoom:

• Naphthalene Superplasticizer:Nws muaj lub peev xwm loj-txo lub peev xwm, txo cov ntsiab lus dej thaum muaj kev tswj hwm. Nws txhim kho cov flavability thiab ua haujlwm ntawm cov sib tov.
• Sodium Lignosulfonate:Qhov no kuj yuav txo cov ntsiab lus dej, txawm hais tias nws cov nyhuv tsis yog muaj zog li naphthalene-based superplasticizers. Nws txhim kho lub zog ua haujlwm, tab sis kom tsawg dua.

3. Detarding Khoom:

• Naphthalene Superplasticizer:Feem ntau tsis ua pov thawj teeb tsa cov khoom ntiag tug.
• Sodium Lignosulfonate:Tej zaum yuav muaj cov khoom me me-retarding, muaj txiaj ntsig hauv cov ntawv thov yuav tsum tau ua haujlwm ntev lossis ncua sijhawm.

4.Cub thiab muaj:

• Naphthalene Superplasticizer:Kim kim vim yog cov txheej txheem ua si hauv pawg.
• Sodium Lignosulfonate:Pheej yig dua thiab npaj muaj, feem ntau siv nyob rau hauv cov ntawv thov tsawg dua.

Cov qauv qhia cov qauv tsim qauv lossis cov kws tshaj lij kev rau cov lus qhia txog kev xaiv cov khoom lag luam zoo rau koj cov kev xav tau tshwj xeeb.

Polycarboxylate superplasticizers: Lub Cim Tshiab

Cov neeg ua kom muaj dej ntau tshaj plaws yog polycarboxylate superplasticizers (PCTHALE-based superplasticizers thiab sodium lignosulfonate. PCES tuaj yeem txo cov ntsiab lus dej los ntawm txog 40%, thiab lawv kuj txhim kho cov qauv pore thiab kev sib txuas ntawm cov pob zeb. Qhov kev tshwm sim hauv kev txo qis poob qis, muaj kev tswj cua zoo dua, thiab txhim kho kev ua vaj huam sib luag. PCES kuj pom zoo zoo heev nrog ntau hom kev ua kom xis mas, lawv tswj tau cov kua dej siab, lawv muaj kev ua kom siab nrog cov viscosity minimal.

Vim li cas pce yog zoo dua li naphthalene superplasticizer thiab sodium lignosulfonate:

1. Cov dej siab dua-txo qis txiaj ntsig:Khos txo cov dej ntws ntau dua thaum tswj hwm kev ua haujlwm zoo, ua rau muaj zog thiab ntau dua ruaj khov.
2. Cov haujlwm zoo dua ua haujlwm:CCES muaj ntev ntev ua haujlwm, txawm tias nyob rau lub sijhawm thauj khoom ntev.
3. Txhim kho Flowability thiab tsis muaj zog:PCAG txhim kho qhob zeb qhob los yog txo qhov xav tau rau kev co ntau dhau.
4. Kuj rau Segration:Mob siab txhim kho cohesion thiab tiv thaiv kev sib cais, ua kom muaj kev sib xyaw ua ke ntau dua.
5. Compatibility nrog ntau hom cement:Khi ua tau zoo nrog cov khoom qab zib sib txawv, suav nrog Portland Maas, thiab cov cement zoo.
6. Txo Kev Cuam Tshuam Ib Zos:Pces yog muab tau los ntawm cov khoom siv txuas ntxiv dua tshiab thiab feem ntau suav hais tias yog ib puag ncig ntau ib puag ncig.

Thaum polycarboxylate superplasticizers superplasticizers muaj kev ua tau zoo, ib txwm sab laj nrog tus neeg ua haujlwm ua kom zoo tshaj plaws rau koj daim ntawv thov.
