PCE Superplasticizer Price


Why YIDA PCE

The new PCE (flaky) produced by YIDA is a trans-generational product that surpasses ordinary powder PCE and liquid PCE. It has four main advantages:


1. Non-liquid form, convenient for cross-border and cross-regional transportation.

2. PCE solution with any solid content can be configured, suitable for long-term storage.

3. High water-reducing rate, which can effectively improve the performance of concrete.

4. The price is cheap, and the comprehensive cost is lower than that of powder PCE.


Polycarboxylate Based Superplasticizer

Polycarboxylate water reducer is a kind of high performance water reducer, and it is a kind of cement dispersant in the application of cement concrete. Widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects. It is synthesized by in-situ polymerization grafting method, first polymerization and then functionalization method and monomer direct copolymerization method.

PCE Polycarboxylate Ether

The popularization and development of PCE is because in many concrete projects, traditional high-efficiency concretes such as naphthalene series are more and more unable to meet engineering needs due to the limitations of technical performance. PCE can prevent the loss of concrete slump without causing obvious retardation, and has a high plasticizing effect at low dosage, and has good fluidity retention.


Polycarboxylate Superplasticizer Factory

Generally, factories that produce PCE use the following two methods:


  • Polymerization then functionalization

This method is mainly to synthesize the main chain of the superplasticizer first, and then introduce the side chain for functionalization by other methods. This method is difficult to operate, the molecular structure of the superplasticizer is inflexible, and the compatibility between the monomers is not good, making it difficult to operate. The use of this method has been greatly restricted.


  • Monomer direct copolymerization

In this method, the active macromonomer is prepared first, and then the small monomer and the macromonomer are copolymerized in an aqueous solution under the initiation of an initiator. As the synthesis process of macromonomers becomes more and more mature and there are more and more types, this synthesis method has become the most commonly used method for the synthesis of polyvinyl acid superplasticizers at this stage.


PCE Superplasticizer Price

At present, polycarboxylate superplasticizers are highly sought after, driving demand to expand, which is also an important reason for the steady rise in prices. The price of polycarboxylate water reducing agent is affected by polyethylene glycol monomethyl ether (MPEG), allyl polyethylene glycol (APEG), methyl hexyl polyoxyethylene (TPEG), three main raw materials, and Other raw materials include acrylic acid, methacrylic acid, maleic anhydride and other raw material prices.
