Professional R&D and excellent quality plasticizer chemicals

by year, but liquid polycarboxylate superplasticizer cannot meet the needs of these industries. At present, there are researches on solid polycarboxylic superplasticizer in China. We use spray drying technology or bulk polymerization to obtain powder polycarboxylic superplasticizer usually[2].

The prerequisite to synthesize PCE was to prepare new macromonomers with controlled molecular mass, adjustable hydrophilic-lipophilic groups, long-chain alkyl groups, and large terminal hydroxyl groups as well. Structural modifications in the molecular scale of polycarboxylate superplasticizer (PCE) would lead to changes in properties of dispersion and water retention as well as enhancement in

The study shows that the flow retaining behaviors of polycarboxylate superplasticizer can be significantly improved by BA modified with hydroxyl-terminated of the side chains of polycarboxylic superplasticizer. Keywords: Polycarboxylate superplasticizer hydroxyl-terminated benzoic anhydride adsorption dispersion

Joyforce Industrial, founded in the year 1999, initially started her operation in serving customers for construction chemicals. Nowadays, she is an important joint manufacturing enterprise of water soluble polymer chemicals and building material additives in China, and has the dominant products Polyvinyl Alcohol (PVA, PVOH), Polycarboxylic Acid Superplasticizer, Hydroxy Propyl Methyl Cellulose

The effects of various factors on the synthesis process and the performances of product, including batch feeding way and the dosage of the radical initiator, the system concentration, the reaction temperature and the reaction time were discussed. A kind of polycarboxylate superplasticizer with allyl alcohol polyethylene glycol, maleic anhydride and methacrylic acid sulfonic sodium as main raw
