Progresses in Synthesis of Polycarboxylate Superplasticizer
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
TPEG – Murrun Environmental Technology Additives
描述. Inquiry. TPEG is the raw materials to produce polycarboxylate supeplasticizer with verygood slump retaining performance. Which is widely used in premix ofcommon concrete, gushing concrete, hydro concrete, also suitable for engineering projects under various weathers and primarily for usingin hot climate area. Properties and Uses:
POLYCARBOXYLATE SUPERPLASTICIZER(PCE) - LIGNOSULFONATE
Product Description. POLYCARBOXYLATE SUPERPLASTICIZER(PCE) is a dry powdered polycarboxylate superplasticizer, with a long polyoxyethylene (PEO) chain and a terminal carboxylic group was synthesized from a modified polyether (SAE-IPEG) to increase its performance in cement , electronegative carboxylic acid group as a terminal group into the long polyoxyethylene chain of PCE, which reduced the
POLYCARBOXYLATE SUPERPLASTICIZER(PCE) – GREEN-POLYMERCHEM
Uses. When used as a high range water reducer, Supercizer PCE will reduce water requirements up to 40% and increase concrete compressive strength at all ages, reduce permeability, and increase durability. When used to increase slump, typically 1 bag per yard of concrete will increase slump by 6-8 inches. This product is recommended for all
- What is a polycarboxylate superplasticizer?
- A series of polycarboxylate superplasticizers (PCEs) with varying carboxyl densities were synthesized at room temperature using the molecular design principle. The PCEs molecular structure was determined using 1 H NMR and MALDI-TOF. The paste fluidity, foam stability as well as other performance of PCEs obtained was also tested.
- What is a polycarboxylic superplasticizer (PCE)?
- Polycarboxylic superplasticizers (PCEs) have been regarded as key materials for high-performance concrete preparation due to their low dosage, good slump maintenance, and high water-reducing rate [1, 2].
- What is TPEG?
- TPEG is a kind of main raw material (polycarboxylate ether monomer) for producing high performance water reducing type and slump retention type polycarboxylate superplasticizer, it is produced with isopentenol and ethylene epoxide as main raw materials.
- What are the preparation methods for polycarboxylate superplasticizer?
- There are three common preparation methods for polycarboxylate superplasticizer: insitu graft copolymerization [5, 6], macromonomer direct copolymerization [7, 8, 9, 10] and post-polymerization functionalization [11, 12].
- How are retarded cellulose-based polycarboxylic acid superplasticizers prepared?
- Retarded cellulose-based polycarboxylic acid superplasticizers were prepared by free radical polymerization of isopentenyl polyoxyethylene ether (TPEG-2400), acrylic acid (AA) and cellulose maleate as monomers in aqueous solution.
- What is hpeg (Polycarboxylate ether monomer)?
- HPEG is a kind of main raw material (polycarboxylate ether monomer) for producing high performance water reducing type polycarboxylate superplasticizer, it is produced with methallyl alcohol and ethylene epoxide as main raw materials.
