1. Qhov ntau npaum li cas yog 0.4% ~ 2.5% ntawm qhov hnyav tag nrho ntawm cov khoom siv cementing, thiab kev siv ntau npaum li cas yog 0.8% ~ 1.5% .Txoj kev ntsuas haum yuav tsum tau nqa tawm ua ntej siv txhawm rau txhawm rau cov ntsiab lus zoo dua.
2. Tsis txhob sib tov nws nrog naphthalene series high-efficiency dej-txo tus neeg sawv cev. Thaum siv cov polycarboxylic acid dej-txo tus neeg sawv cev, yaug cov khoom sib tov thiab cov khoom siv uas tau siv naphthalene series cov dej ua kom muaj zog-txo tus neeg sawv cev, txwv tsis pub cov dej-txo cov nyhuv yuav ploj.
3. Thaum siv polycarboxylic acid dej tsim tawm, nws tuaj yeem ntxiv ncaj qha rau hauv daim ntawv ntawm cov kua ua kua lossis npaj rau hauv kev daws nrog qee qhov kev txiav txim siab, thiab cov dej coj mus rau hauv dej siab coj ua dej ntawm polycarboxylic acid series tuaj yeem txiav tawm Cov.
4. Raws li cov dej txo tus nqi ntawm cov pob zeb ua kev sib xyaw nrog polycarboxylic acid dej hloov dua tshiab yog loj dua, cov nqes dej yog nkag siab zoo dua rau cov kev siv dej, thiab kev noj haus dej yuav tsum tswj hwm thaum siv.
5. Polycarboxylic acid dej reducer muaj kev yoog tau zoo nrog feem ntau cov cement, tab sis qee cov cement yuav muaj qhov dej tsawg dua thiab cov nqes dej loj dua.Qhov ntxiv, zoo nkauj thiab lub sijhawm tso ntawm cov cement tseem yuav cuam tshuam rau kev siv polycarboxylic acid dej reducer.Yog qhov no lub sijhawm, nws tau pom zoo kom nce cov tshuaj kom tsim nyog lossis sib xyaw lwm cov ntu qeeb los daws qhov teebmeem.
6, tom qab kev txuas ntxiv ntawm polycarboxylic acid dej tsim tawm, cov ntsiab lus huab cua ntawm cov pob zeb nce (feem ntau 2% ~ 5%) yog qhov zoo rau kev txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm kev ua vaj tse, yog tias koj yuav tsum siv rau hauv cov qhob steamed lossis muaj lwm yam tshwj xeeb. , thov hu rau peb, peb rau koj qhov kev daws teeb meem raws sijhawm.
7. Vim tias tus nqi me me thiab dej siab txo tus nqi ntawm polycarboxylic acid dej-txo tus neeg sawv cev, kev siv cov polycarboxylic acid dej-txo tus neeg sawv cev los npaj ntau yam kev ua haujlwm siab ua haujlwm siab tshaj C45 tuaj yeem txo tus nqi kho mob, nrog rau cov txuj ci tseem ceeb thiab cov txiaj ntsig kev lag luam; Txawm hais tias tus nqi polycarboxylic acid dej tsim tus nqi tsim yog qhov siab, nws tuaj yeem txo cov nqi sib xyaw ntawm cov pob zeb ua ke los ntawm kev nce nqi ntawm pob zeb hauv av admixture, thiab nws kuj muaj qee yam txiaj ntsig kev lag luam thiab nyiaj txiag.
