Polycarboxylate Ether PCE Powder form Superplasticizer Manufacture of High Strength Concrete

JF POLYCARBOXYLATE SUPERPLASTICIZER POWDER (02)

Synonyms:PCE Super Plasticizer

At present, most polycarboxylic acid water-reducing agent is synthesized by the esterification of methoxy polyethylene glycol to synthesize large monomer and copolymerization of other monomers. Benzene or toluene is usually used as water-carrying agent in the esterification process, and benzene or toluene vapor is a toxic substance. Polycarboxylic acid superplasticizer from concrete performance, price, environmental protection, sustainable development and other aspects of comprehensive consideration, further toward high performance, multi-functional, ecological direction of development, low price, simple synthetic process of polycarboxylic acid superplasticizer on concrete materials, construction progress has important significance.

PCE Water Reducer Application:

1. Polycarboxylic acid water reducing agent is environmentally friendly and non-toxic.
2. Polycarboxylic acid water reducing agent can make concrete harden and have good durability. The strength of each concrete age is very high. Good volume stability and anti-permeability, good freeze-thaw, anti-corrosion and anti-carbonization effects.
4. Polycarboxylic acid water reducer is widely applicable to all mixed materials, such as Portland cement, ordinary Portland cement, slag silicate, fly ash cement and pozzolan cement.
3. Polycarboxylic acid water reducing agent has strong dispersibility and high water reducing rate. Suitable for making high-strength concrete.
5. Polycarboxylic acid water reducing agent can effectively reduce the viscosity of concrete, has good adhesion, moderate air content, and is suitable for pumping.

Polycarboxylate Superplasticizer Production Method:

1. One-step method, using active polyether and active monomer to polymerize in an aqueous solution, the reaction temperature is 60 degrees, and the reaction time is 8-9 hours. The product features of the process are high water reduction, good slump retention, that is, good fluidity maintenance, simple process, easy control, and stable product quality. Suitable for occasions such as commercial concrete.

2. Two-step method, using MPEG to prepare active macromonomer, macromonomer, reaction time 9-10 hours, using solvent-free process. The second step adopts aqueous solution polymerization to copolymerize the macromonomer and other active monomers. The reaction time is 8-10 hours and the temperature is 80 degrees. The product features of this process have a large water reduction rate, a general fluidity, and a high early strength. According to different applications, different products can be designed, and the products are variable and adjustable.
