Polyethylene oxide PEO special material for cement mortar
0.2%-0.4% high molecular weight PEO was added to the cement slurry. It can improve the water retention of the slurry, greatly improve its transportability, and can inhibit the flying of dust and improve the production environment. PEO is also used as an additive for underwater use of cement.
Polyethylene oxide PEO special material for cement mortar Main performance advantages:
1. Special fine powder polyethylene oxide has good solubility, can quickly dissolve, and can meet customer's requirements for viscosity in 1-2 minutes.
2. Non-ionic polymer, which does not react with cement, has good compatibility with various inorganic binder materials, fillers, and common chemical additives.
3. Has excellent dispersion, lubricity and water retention.
4. Improve the viscosity of the concrete mortar system, increase the viscoelasticity, and improve the construction workability.
5. Improve the cohesion between cement, lime, gypsum and other cementitious materials and aggregates, and improve the adhesion of mortar to various substrates.
6. Decrease the elastic modulus of the mortar to improve the elasticity and flexibility of the mortar so that the mortar can withstand a certain substrate deformation, external force
Impact, temperature difference deformation, influence of freeze-thaw deformation.
