HPEG-2400 Polycarboxylate superplasticizer polyether monomer
Polycarboxylic acid high-performance water reducer has good comprehensive technical performance advantages and environmental protection characteristics, which meets the needs of modern concrete engineering. Therefore, polycarboxylic acid based high-performance water reducer is gradually becoming the preferred admixture for preparing high-performance concrete.
Compared with the traditional concrete water reducer, like Lignosulphonate based water reducer, Sulphonated naphthalene water reducer(SNF), JLY series Polycarboxylate superplasticizer has the outstanding advantage as below:
1, Low dosage
2, Excellent water reducing rate over 30%
3, Obvious reinforcement on Concrete strength
4, Good compatibility with Cement
5, Superior performance on Concrete slump retention
6, Eco-friendly water reducing agent, No pollution during production.
■ CH2=C(CH3)CH2O(CH2CH2O)nH, n=10~60
■ HPEG-2400 is a polyoxyethylene methallyl ether with molecular weight 2400.It’s produced by methallyl alcohol and ethylene epoxide as main raw material.
■ This product is the main raw material for high performance polycarboxylate superplasticizer
■ The water reducer from this material(HPEG-2400) has superior dispersibility, low dosage, high water reducing rate, high adhesive force, good reinforcing effects.
■ The water reducer from this material has high durability,can efficiently reduce the water/gel ratio, enhance durability, reduce risk of shrinkage and creep.
■ HPEG-2400 is non-toxic, non-corrosion, good water solubility.
■ The water reducer from this material is environment friendly, corrosive free to steel bar, comply with the ISO 14000 international environment protection management standard.
PCE made from HPEG-2400 can be used to produce high performance, high strength commercial concrete at work site or long-distant convey.
