Alkali-free solid setting agent product manual
Alkali-free setting agent is a new type of environmentally friendly alkali-free, chlorine-free high-performance setting agent. It has a strong function of accelerating cement solidification, and can also greatly improve the early and late cement strength, as well as improve the anti-seepage ability.
Ingredients: This product is an alkali-free quick-setting agent product of aluminum sulfate system, which is non-toxic, harmless, non-radioactive, non-corrosive, non-flammable and non-explosive.
Safety tips: Avoid contact with skin and glasses; if contact occurs, rinse with clean water. If splashed into eyes, wash with plenty of clean water or seek medical attention. Wear a mask and goggles when contacting powdered products.
Storage conditions: The inner and outer packaging bags of instant powder should be intact to prevent water absorption and moisture. After being prepared into liquid, the storage temperature should be greater than 5ºC. Liquid finished products should be stored in plastic/glass fiber reinforced plastic barrels. The pH value of this product is weakly acidic and will react chemically with steel materials. Avoid using iron barrels for storage.
