Nws yog cov kws tshaj lij thiab kev lag luam loj ntawm cov lag luam koom nrog kev tsim cov pob zeb ua kev cog qoob loo.Nws yog ib qho ntawm cov khoom lag luam Admixture Polycarboxylic Acid Hoobkas hauv Suav teb.
Peb muab cov khoom ntawm cov khoom ntawm Pob Zeb Ua Si Admixture Polycarboxylic Acid, Rau pob zeb ua ke, cov khoom tseem ceeb yog polycarboxylate superplasticizer thiab so on.it tuaj yeem siv hauv kev tsim kho.
Concrete Admixture Polycarboxylic Acid Hoobkas - Cov yam ntxwv ntawm cov khoom ua kom dej yog qhia luv luv
Cov qauv tsim cov qauv ntawm polycarboxylic acid superplasticizer zoo li cov zuag, thiab nws cov saw tseem ceeb muaj cov pawg nquag dua, xws li acid pawg (COOH), sulfonic acid pawg kaw (SOH), hydroxyl pawg (ib OH), thiab polyethane oxygen pab pawg (- (CH1CH2O0).
Cov qauv tsim cov qauv ntawm polycarboxylic acid superplasticizer zoo li cov zuag, thiab nws cov saw tseem ceeb muaj cov pawg nquag dua, xws li acid pawg (COOH), sulfonic acid pawg kaw (SOH), hydroxyl pawg (ib OH), thiab polyethane oxygen pab pawg (- (CH1CH2O0) .- R), thiab lwm yam Cov nyhuv ntawm txhua pab pawg ntawm cov cement yog txawv, piv txwv li, amine pawg muaj zoo dua dispersibility thiab retarder effect.Lub sulfonic acid pawg muaj dispersibility zoo; Hydroxyl tsis tsuas yog muaj cov nyhuv retarding , tab sis kuj tseem ua lub luag haujlwm ntawm ntub dej.Polyethane - hydroxyl pawg muaj cov haujlwm ua kom tswj cov yam ntxwv ntws tawm.Many cov kws tshawb fawb tau kawm txog kev sib txheeb ntawm cov qauv thiab cov khoom ntawm polymeric acid series dej-txo cov neeg ua haujlwm los ntawm kev sib txawv.
Qee tus kws tshawb fawb tau kawm txog cov qauv molecular ntawm pawg ua haujlwm thiab cov dej ua kom txo qis rau tus yam ntxwv ntawm cov pob zeb ua kom tawg cov yam ntxwv, qhov xaus yog: cov qauv molecular ntawm poly (carboxylic acid series dej txo tus neeg sawv cev ntawm hydroxyl cob puag thiab carboxyl mole piv ntawm 1: 1 . 5, poly carboxylic acid series ntawm cov dej reducer rau pob zeb ua kom muaj cov khoom zoo los tiv thaiv kev sib tsoo, nkhaus saw polymerization degree yog qhov loj dua, dej txo tus neeg sawv cev ntawm molecular phaus, txhim kho qhov tawg tsis kam ntawm pob zeb ua; Cyclic thiab sulfonic acid pawg muaj cawv me ntsis ntawm kev tawg. tsis kam ntawm pob zeb ua.
Qee tus kws tshawb fawb tau kawm txog kev cuam tshuam ntawm cov qauv sib txawv polycarboxylate superplasticizers ntawm cov yam ntxwv ntawm cov xis mas muab tshuaj.Qhov kev tshwm sim qhia tau tias cov dej-txo tus neeg sawv cev nrog qis sab ua ke cov khoom siv tsawg, nruab nrab ceev thiab qhov siab sib xyaw molecular muaj zoo dua dispersibility, ntau dua adsorption nqi ntawm cov cement lus hais thiab muaj zog retarder nyhuv.
Kev sib xyaw ua ke tuaj yeem ua rau kev ua haujlwm ntawm polycarboxylate superplasticizer ntau dua, tab sis nws tsis tuaj yeem daws cov teeb meem ntawm lub hauv paus.Only thaum kev sib raug zoo ntawm cov qauv molecular thiab cov khoom ntawm lub superplasticizer yog qhov pom tseeb, lub superplasticizer nrog cov khoom zoo heev thiab cov kev xav tau engineering tuaj yeem tsim los ntawm lub zeem muag ntawm cov qauv tsim qauv molecular.
