Polycarboxylate dej reducer rau cov khoom siv hauv tsev

Polycarboxylate Superplasticizer yog cov dej-txo cov neeg ua haujlwm siab thiab cov cement dispersant hauv kev siv cov cement pob zeb. Chemically, nws tuaj yeem muab faib ua ob pawg. Cov saw tseem ceeb yog methacrylic acid, thiab sab saw yog Carboxylic acid pawg thiab MPEG (Methoxy polyethylene glycol), polyester qauv. Lwm cov saw tseem ceeb yog polyacrylic acid, thiab sab saw yog Vinyl cawv polyethylene glycol, nrog cov qauv polyether.

Polycarboxylate superplasticizer muaj cov nyhuv dispersing zoo ntawm cov cement, uas tuaj yeem txhim kho cov dej ntws ntawm cov cement sib tov thiab cov pob zeb ua pob zeb, thiab tib lub sijhawm txo cov dej haus, ua kom cov pob zeb ua haujlwm zoo, thiab txo cov pob zeb poob. Nws tuaj yeem txo cov dej haus zoo heev thiab txhim kho lub zog ntawm pob zeb txhua hnub.
