Raws li qhov ntsuas kub txuas ntxiv sawv, lub caij nplooj ntoo hlav tuaj txog, thiab dab tsi hauv kev cuam tshuam ntawm kev hloov pauv ntawm qhov kub thiab txias sib txawv. Hauv qhov no, peb yuav ua kom haum raws li kev hloov kho thaum siv cov neeg sawv cev dej hauv kev txiav txim kom cov pob zeb nce mus txog cov khoom siv.

1. Polycarboxylate dej-txo cov neeg sawv cev tseem muaj teeb meem nrog lawv hloov kho kom xis mas. Rau cov tib neeg cov cai, cov dej-txo tus nqi yuav qis thiab poob qis yuav loj. Yog li ntawd, thaum qhov yoog tau ntawm cov cement tsis zoo, muaj kev sib tov thiab kev hloov kho ntawm cov pob zeb yuav tsum tau ua. noj tshuaj kom ua tiav cov txiaj ntsig zoo tshaj plaws.

Tsis tas li ntawd, lub sijhawm ua tiav thiab lub sijhawm khaws cia ntawm cov ntseeg yuav tseem yuav cuam tshuam qhov ua tau zoo ntawm polycarboxylate superplasticizer. Kev siv cov paas xis kub yuav tsum raug zam nyob rau hauv kev tsim khoom. Yog kub xis mas tov nrog polycarboxylate dej-txo cov neeg sawv cev, tabsis cov pob zeb tawg yuav tsis muaj zog, thiab cov qhob yuav tshwm sim. Sai sai poob ntawm slump.

2. Polycarboxylate dej-txo cov neeg sawv cev muaj kev nkag siab ntau rau kev hloov pauv ntawm cov khoom nyoos. Thaum cov khoom siv raw xws li cov ntaub ntawv xuab zeb thiab cov pob zeb zeb thiab cov khoom noj qab zib thiab pob zeb tshauv thiab cov neeg sawv cev ntawm cov pob zeb-txo cov dej num polycarboxylate dej paug. Cov kev ua tau zoo ntawm cov pob zeb yuav raug cuam tshuam rau qee yam, thiab kev sib xyaw sib xyaw ua ke yuav tsum tau nqa tawm cov khoom siv hloov pauv hloov kho kom ua tiav cov nyhuv zoo.

3. Lub polycarboxylate Dej-txo tus neeg sawv cev yog tshwj xeeb tshaj yog nkag mus rau cov av nkos cov ntsiab lus ntawm cov lus sib sau ua ke. Cov ntsiab lus av nkos ntau dhau yuav txo cov kev ua tau zoo ntawm polycarboxylate dej-txo tus neeg sawv cev. Yog li ntawd, qhov zoo tshaj ntawm aggregates yuav tsum nruj me ntsis tswj tau thaum siv polycarboxylate superplasticizers. Thaum cov av nkos cov ntsiab lus ntawm kev sib sau ua ke, cov tshuaj ntawm polycarboxylate dej-txo tus neeg sawv cev yuav tsum tau nce.

4. Vim tias cov dej ntws ntawm polycarboxylate dej-txo tus neeg sawv cev, cov pob zeb poob qis tshwj xeeb yog siv. Yog li ntawd, cov dej tau haus yuav tsum muaj kev tswj hwm nruj me nyuam thaum siv. Thaum cov nyiaj tau dhau lawm, cov pob zeb yuav tshwm sim cais, los ntshav, ua kom tawv nqaij tawv thiab lwm yam kev tsis zoo.

5. Thaum siv polycarboxylate dej-txo cov lus admixtures, yog li cov khoom siv sib xyaw ua ke, yog li cov khoom siv sib xyaw ua ke, yog li cov khoom siv sib xyaw ua ke, yog li cov khoom siv sib xyaw ua ke, yog li cov khoom siv sib xyaw ua ke Ntau yooj yim tau siv zog, uas yooj yim rau kev tswj hwm ntawm pob zeb tawg hauv kev tsim khoom. Yog tias lub sijhawm sib xyaw tsis txaus, nws yog qhov ntau heev uas cov pob zeb ntawm cov chaw tsim khoom yuav loj dua li cov pob zeb ntawm cov pob zeb ua haujlwm ntawm chaw nres tsheb sib xyaw.

6. Nrog kev tawm tsam lub caij nplooj ntoo hlav, qhov sib txawv ntawm qhov sib txawv ntawm ib hnub thiab hmo ntuj hloov zoo heev. Nyob rau hauv kev tswj ntau lawm, peb yuav tsum tau them nyiaj rau cov kev hloov pauv thiab kho cov tshuaj ntawm cov kev sib xyaw kom tsawg thiab kub ntawm qhov kub thiab txias).
