Shenzhen Chenggong Building Materials Co., Ltd. suppling (type WRA-1) Water-reducing Reinforcing Additive for high-strength Land Plaster & Gypsum Product.
Compared with ordinary melamine type Water-reducing Additive, (type WRA-1) Water-reducing Reinforcing Additive can increase water-reducing ratio 15%-20%, and the dry strength and wet strength of gypsum both can be increased 30%-200%.
After mixing (type WRA-1) Water-reducing Reinforcing Additive into the gypsum, compared with mixing traditional melamine type Water-reducing Additive, the viscosity of gypsum slurry is smaller, solid content is higher, and it is more better for construction, keeping-water and fluidity.
Type WRA-1 Water-reducing Reinforcing Additive also has the common characteristics as traditional melamine type Water-reducing Additive, for example non air-entrainment, good steam-cured adaptability, no slow-setting action for gypsum, no rusting and corroding for reinforcing steel bar, innocuity, no pollution.
(type WRA-1) Water-reducing Reinforcing Additive is suitable for making high-strength land plaster, building land plaster of bigger water-requirement in standard consistence, special for chemical land plaster and its goods.
Recommended mixed quantity: 0.2% to 0.6% of land plaster or gypsum by weight.
