Polycarboxylic acidCov dej txo cov neeg ua haujlwm yuav ntsib ntau yam teeb meem hauv kev siv tswv yim.Tam sim no cia peb suav cov teeb meem tshwm sim hauv kev siv engineering thiab lawv cov kev daws teeb meem.
Thawj yog cov av nkos ntawm cov xuab zeb.Thaum cov av nkos cov ntsiab lus ntawm cov xuab zeb yog siab, tus nqi txo se ntawmpolycarboxylic acid dej-txo tus neeg sawv cevyog txo qis, thiab qhov kev hloov pauv tsis pom tseeb thaum cov ntsiab lus nce.Kev daws: Siv cov xuab zeb no rau qib qis zoo tib yam pob zeb;nruj me ntsis tswj cov av nkos cov ntsiab lus ntawm cov xuab zeb thiab xav kom cov av nkos yuav tsum tsawg tshaj li 2%.
Qhov thib ob yog qhov teeb meem insoluble ntawm xuab zeb thiabpolycarboxylic acid dej txo tus neeg sawv cev.Thaum gradation, av nkos cov ntsiab lus, thiab av nkos cov ntsiab lus ntawm cov xuab zeb ua tau raws li qhov yuav tsum tau ua, nws tsis yaj nrog polycarboxylic acid dej txo tus neeg sawv cev.Cov tshuaj muaj pes tsawg leeg tsis sib haum nrog cov muaj pes tsawg leeg ntawm covpolycarboxylic acid dej-txo tus neeg sawv cev, thiab cov pob zeb sib xyaw tsis muaj fluidity.Kev daws: Rau txhua pawg ntawm cov xuab zeb nkag mus rau hauv qhov chaw, yog tias lub cev ntsuas tau tsim nyog, rov ua dua qhov kev tsim vaj tsev sib xyaw kom tshem tawm cov xuab zeb insoluble ntawm qhov chaw.
Tom qab ntawd cov pob zeb poob qis yog nrawm, uas yuav tsum taucov chaw tsim khoom ntawm dej txo tus neeg sawv cevtxhawm rau ntxiv tus neeg sawv cev slump retention, thiab tom qab ntawd siv cov ntaub ntawv raw ntawm qhov chaw los ua qhov kev sim rov qab ntawm qhov sib xyaw kom kho qhov poob qis kom ua tau raws li kev tsim kho.
Qhov kawg yog qhov tshwm sim ntawm pob zeb los ntshav.Nyob rau hauv cov dej nag, C50 pob zeb tau nchuav thiab cov pob zeb tau muab tshem tawm los ntawm lub tanker nyob rau hauv qhov zoo, tab sis tom qab cov pob zeb vibrated, muaj los ntshav thiab sib cais.Kev daws: Txo cov dej noj, ncua sij hawm sib xyaw, txo 0.1% cov ntsiab lus, cov pob zeb vibrating tsis los ntshav, thiab ua cov qauv pob zeb nrog 28-hnub compressive zog kom ncav cuag lub zog tsim.
