PCE Polycarboxylate Superplasticizer

Kev tsim kho tshuaj pob zeb sib xyaw PCE polycarboxylate superplasticizer (xws li dej reducer, vulcanizing agent, thiab lwm yam) muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm pob zeb. Ib qho me me ntawm cov khoom sib xyaw tuaj yeem ua rau cov pob zeb ua haujlwm tau zoo yam tsis muaj cov ntsiab lus ntawm cov cement. Nws tsis tsuas yog txhim kho cov fluidity ntawm qhov sib tov, tab sis kuj tseem txhim kho cov cohesion thiab dej tuav kev ua tau zoo ntawm qhov sib tov, thiab txhim kho lub zog thiab durability ntawm cov pob zeb. Raws li lub cev thiab tshuaj lom neeg ntawm cov khoom sib xyaw ua ke, cov dej txo qis tuaj yeem ua lub luag haujlwm hauv qab no.

(1) Cov tshuaj siv ua vaj tse pob zeb sib xyaw PCE polycarboxylate superplasticizer tuaj yeem cuam tshuam cov cement hais kom sib txawv. Nws tuaj yeem ua rau cov cement dej condensation rau hauv flocculent block tawg, ntxiv rau ntau hom dej txo tus neeg sawv cev ntau dua los yog tsawg dua qee qhov huab cua, kom cov viscosity ntawm cov cement slurry txo, nce mFobility, tuaj yeem ua pob zeb hauv txhua qhov sib npaug tsis hloov cov xwm txheej, lub fluidity ntawm qhov sib tov zoo heev. Cov nyhuv no yog qhov tsim nyog rau kev ua haujlwm thiab kev tsim kho tshuab.

(2) Kev hloov cov dej-cement piv tau zoo, kho qhov sib xyaw kom zoo, thiab txo cov dej-cement piv tuaj yeem ua rau cov pob zeb muaj fluidity zoo ib yam li yam tsis muaj qhov sib ntxiv ntawm cov dej reducer.

(3) Cement tuaj yeem khaws cia kom zoo yam tsis hloov pauv qhov dej ntawm qhov sib xyaw thiab lub zog ntawm cov pob zeb tawv tawv. Vim hais tias cov dej-txo tus neeg sawv cev ntxiv, qhov yuav tsum tau muaj zog tuaj yeem hloov cov dej-cement piv, thiab cov dej-txo tus neeg sawv cev yog tov nrog cov kua kom nce, yog li cov cement tsawg npaum li cas ntawm cov pob zeb yuav siv tau, thiab lub zog thiab fluidity nyob rau theem tom ntej ntawm qhov project tuaj yeem ua tiav, uas txo cov nqi ntawm cov cement pob zeb ua lub luag haujlwm hauv kev txuag cov cement. Cov dej ntws dav dav tuaj yeem txuag tau 5% mus rau 10% ntawm cov cement thaum siv zoo, thiab cov dej txo qis tuaj yeem txuag tau ntau dua.

Kev cuam tshuam ntawm cov dej reducer ntawm cov khoom vaj khoom tsev

① Kev cuam tshuam ntawm cov dej txo tus neeg sawv cev ntawm cov khoom rheological ntawm cov pob zeb tshiab

Txhawm rau npaj cov pob zeb tshiab nrog cov khoom ntws zoo, nws yog ib qho tsim nyog yuav tsum tshem tawm cov kua nplaum uas txo cov dej ntws ntawm cov cement hais, kom cov cement hais kom tag nrho dispersed nyob rau hauv nruab nrab aqueous. Muaj ntau yam khoom uas cuam tshuam rau cov cement fusion, xws li cov ntxhia hauv cov cement, cov duab thiab qhov loj ntawm cov cement hais, kev ncaj ncees ntawm cov pob zeb hauv av, kev ua haujlwm thiab ib puag ncig. Cov yam ntxwv no ncaj qha lossis tsis ncaj qha tswj kev ruaj ntseg ntawm cov cement hais hauv cov cement slurry. Cov kev sib txawv nruab nrab yuav hloov tus nqi ntawm cov cement hais hauv cov cement slurry, uas yog, electrostatic repulsion ntawm cov khoom.

② Kev cuam tshuam ntawm cov dej txo tus neeg sawv cev ntawm kev ua haujlwm ntawm cov pob zeb tshiab

Muaj ntau yam cuam tshuam rau kev ua haujlwm ntawm cov pob zeb tshiab, feem ntau suav nrog cov cement, aggregate, dej siv, xwm thiab tus nqi ntawm admixtures, kub thiab lwm yam. Raws li tib yam li lwm yam kev mob, kev ua haujlwm ntawm superplasticizer muaj feem xyuam rau hom thiab tus nqi ntawm superplasticizer. Kev ua haujlwm ntawm cov pob zeb tshiab feem ntau yog ntsuas los ntawm tus nqi poob qis. Tom qab lub pob zeb sib xyaw ua ke yog nchuav, nws yuav siv sij hawm ib lub sij hawm los thauj, tos, thiab chaw nres tsheb, uas feem ntau ua rau kev ua haujlwm ntawm cov pob zeb tsis zoo thiab ua rau muaj teeb meem kev tsim kho.
