PCE-Polycarboxylate Superplasticizer Hmoov

Polycarboxylate superplasticizers (PCE) yog cov khoom siv ua haujlwm siab siv los txhim kho kev ua haujlwm, ntws, thiab lub zog ntawm cov pob zeb sib xyaw. Lawv feem ntau muaj nyob rau hauv ob hom kua thiab hmoov, nrog rau cov hmoov daim ntawv yog tshwj xeeb tshaj yog yooj yim rau kev thauj mus los, cia, thiab dosing lub hom phiaj. Nov yog cov lus piav qhia ntawm PCE hmoov, nws cov khoom, thiab nws cov ntawv thov:

1. Khoom ntawm PCE Hmoov:

• High Purity: PCE hmoov yog tsim los nrog siab purity kom ntseeg tau tias kev ua tau zoo thiab kev sib raug zoo nrog ntau yam kev tsim ua vaj tse.
• Fine Particle Size: Cov hmoov daim ntawv ntawm PCE yog finely hauv av, tso cai rau sai dispersion thiab dissolution nyob rau hauv dej los yog qhob mix.
• Kev Txo Dej Muaj Peev Xwm: PCE hmoov nthuav tawm cov khoom txo cov dej zoo, ua kom txo qis hauv dej-rau-cement piv tsis cuam tshuam rau kev ua haujlwm lossis lub zog ntawm cov pob zeb sib xyaw.
• High Dispersion Efficiency: PCE hmoov muaj kev ua haujlwm siab dispersion, ua kom muaj kev faib tawm ntawm cov cement thiab lwm yam khoom xyaw hauv cov pob zeb sib xyaw. Qhov no ua rau kev txhim kho qhov sib xws thiab homogeneity ntawm cov pob zeb.
• Kev Ruaj Ntseg Ceev: PCE hmoov tso cai rau kev tswj xyuas meej ntawm lub sijhawm teeb tsa ntawm kev ua vaj tse, ua kom muaj kev hloov kho kom tau raws li cov kev xav tau tshwj xeeb thiab ib puag ncig.

2. Kev siv ntawm PCE Hmoov:

• Npaj-Mix Concrete: PCE hmoov yog siv dav hauv kev tsim cov pob zeb sib xyaw ua ke, qhov uas nws pab txhim kho cov dej ntws thiab cov twj tso kua mis ntawm cov pob zeb sib tov, ua rau kev tsim kho sai dua thiab cov qauv ua tiav zoo dua.
• Precast Concrete: Hauv kev tsim cov pob zeb ua ntej, PCE hmoov txhawb kev tsim cov khoom muaj zog, ruaj khov cov ntsiab lus nrog cov npoo du thiab qhov ntev. Nws tso cai rau kom sai demolding thiab tuav ntawm precast Cheebtsam, txo lub sij hawm ntau lawm thiab cov nqi.
• Self-Consolidating Concrete (SCC): PCE hmoov yog qhov tseem ceeb hauv kev tsim cov pob zeb ua tus kheej, uas ntws tau yooj yim thiab ua tiav cov formwork yam tsis xav tau kev co. SCC ua nrog PCE hmoov yog zoo tagnrho rau complex architectural tsim thiab cov qauv nrog congested reinforcement.
• High-Performance Concrete: PCE hmoov feem ntau yog siv rau hauv cov khoom ua haujlwm siab, uas yuav tsum muaj lub zog zoo dua, ua haujlwm ntev, thiab ua haujlwm tau zoo. Nws enables zus tau tej cov pob zeb nrog txhim kho mechanical zog thiab txo permeability.
• Shotcrete thiab Sprayed Concrete: PCE hmoov yog siv rau hauv kev txhaj tshuaj thiab txau cov pob zeb, qhov uas nws txhim kho cov cohesion, pumpability, thiab adhesion ntawm cov pob zeb sib tov rau lub substrate. Qhov no ua rau muaj txiaj ntsig zoo thiab ruaj khov kho pob zeb, qhov hauv ob sab phlu, thiab txoj kab nqes stabilization.
• Cov pob zeb loj: Hauv cov pob zeb loj loj, xws li cov pas dej da dej, txuas hniav, thiab cov hauv paus, PCE hmoov pab txo qis thermal tawg thiab shrinkage los ntawm kev txo cov dej ntawm cov pob zeb sib xyaw. Qhov no txhim kho kev ua haujlwm ntev thiab ua haujlwm ntev ntawm cov pob zeb loj.

3. Cov txiaj ntsig ntawm PCE Powder:

• Txhim Kho Kev Ua Haujlwm Zoo: PCE hmoov txhim kho kev ua haujlwm thiab kev ntws ntawm cov pob zeb sib xyaw, tso cai rau kev tso chaw yooj yim dua thiab sib sau ua ke yam tsis muaj kev sib cais lossis los ntshav.
• Ua kom muaj zog: Los ntawm kev txo cov dej-rau-cement piv, PCE hmoov pab txhawb kom muaj zog compressive ntau dua thiab txhim kho durability ntawm cov pob zeb ua vaj tse.
• Txhim kho Pumpability: PCE hmoov txhim kho lub twj tso kua mis ntawm cov pob zeb sib xyaw, ua kom muaj txiaj ntsig zoo ntawm cov pob zeb hauv cov chaw nyuaj, xws li cov tsev siab siab lossis cov qauv hauv av.
• Txo qhov cuam tshuam ib puag ncig: PCE hmoov pab txhim kho kev siv cov cement thiab dej hauv cov pob zeb sib xyaw, ua rau qis carbon emissions thiab txo qis ib puag ncig hneev taw thaum tsim kho.

PCE hmoov yog ntau yam thiab ua tau zoo ntawm cov pob zeb sib xyaw uas muaj ntau yam txiaj ntsig hauv kev tsim kho kev lag luam. Nws qhov loj me me, dej-txo muaj peev xwm, thiab kev ua haujlwm siab dispersion ua rau nws tsim nyog rau ntau yam kev siv, nrog rau kev npaj sib xyaw ua vaj tse, precast qhob, nws tus kheej-consolidating pob zeb, shotcrete, thiab cov pob zeb loj. Los ntawm kev koom nrog PCE hmoov rau hauv cov qauv tsim, cov kws tsim khoom thiab cov neeg ua haujlwm tuaj yeem ua tiav kev ua haujlwm zoo, lub zog, thiab ua haujlwm ntev hauv cov pob zeb ua vaj tse thaum txhim kho kev tsim kho thiab kev ruaj khov.
