Product Description
Qhov xwm txheej tam sim no ntawm Tuam Tshoj txoj kev lag luam polyether monomer tau txheeb xyuas luv luv, thiab ntau yam thiab kev ua lag luam ntawm lub ntsiab polyether carboxylic acid monomers tau qhia. Pib los ntawm cov qauv molecular ntawm cov monomers sib txawv, qhov zoo thiab qhov tsis zoo ntawm txhua lub monomer thiab nws txoj kev loj hlob kev taw qhia tau soj ntsuam, thiab ib hom tshiab ntawm polycarboxylate dej txo tus neeg sawv cev, ethylene monomer polyethylene glycol ether (EPEG), tau qhia.
Polycarboxylate superplasticizer yog lub cim tshiab ntawm kev sib xyaw ua ke, hu ua lub cim thib peb ntawm kev ua tau zoo superplasticizer. Piv nrog rau naphthalene-raws li superplasticizers, polycarboxylate superplasticizers muaj cov yam ntxwv ntawm cov dej-txo tus nqi thiab zoo adaptability rau cement. Nyob rau tib lub sijhawm, tsis muaj cov dej khib nyiab thiab cov roj pov tseg hauv cov txheej txheem tsim khoom ntawm polycarboxylate superplasticizer, uas yog cov khoom siv ntsuab thiab ib puag ncig zoo.
Poly (carboxylic acid dej txo tus neeg saib xyuas yog muaj cov yam ntxwv ntawm amphiphilic polymer, feem ntau yog nyob rau hauv ob daim ntawv cog lus ntawm qhov kawg ntawm polyoxyethylene ether loj monomer nrog unsaturated carboxylic acid me me molecular monomers, nyob rau hauv cov nyhuv ntawm pib, copolymerization tshuaj tiv thaiv synthesis ntawm monomer rau qhov loj ntawm sab alkenyl lub ntsiab saw molecules yog tsim los ntawm copolymerization, polyether monomer ntawm polyethylene glycol (peg) ntu ntawm sab saw qauv, cov qauv molecular raws li qhia hauv daim duab
Piv nrog rau cov pa reducers, polycarboxylate dej reducers muaj cov yam ntxwv ntawm cov qauv tsim qauv. Lub macromonomer kawg ntawm unsaturated ob daim ntawv cog lus nyob rau hauv cov dej txo tus neeg sawv cev molecule generates cov kua qaub qaum ntawm polycarboxylic acid los ntawm cov tshuaj tiv thaiv polymerization. "Point anchorage", adsorbed rau saum npoo ntawm cov cement hais; polyethylene glycol ceg ntawm macromonomers tsim ib qho kev daws teeb meem polymer saw txheej ntawm cov cement hais los ntawm hydrogen bonding nrog dej molecules. Cov nyhuv steric hindrance yog siv los disperse cov cement hais kom ua tiav cov dej txo cov nyhuv. Yog li, kev txhim kho ntawm superplasticizer yog sib cais los ntawm kev hloov ntawm macromonomer, thiab kev txhim kho ntawm macromonomer molecular qauv tuaj yeem txhim kho cov txheej txheem ntau lawm thiab cov khoom ua tau zoo ntawm polycarboxylate superplasticizer.
