Water-holding agent
Play water conservation, thickening, improve effects such as workability.
Proterties: this product be a kind of white or be with yellowish powder slightly, do not have smell, tasteless, nontoxic.PH value stability: this product viscosity in aqueous solution all is more stable in pH value 3.0～11.0 scopes.
Viscosity: 4～100,000 cps anti-fissuring agents
Lignocellulose: wood fibre is to extract from the wood pulp of beech and fir, and it is divided into the different staple lengths and the finished product of fineness degree by shredding, neutralize, bleach, roll, passing through sub-sieve again, to adapt to the needs of different application material.
Splitting resistance: solidify or drying process in the mechanical energy that produces weakened by the fiber muscle.
The anti-property of hanging down: the phenomenon that drops can not occur in constructing operation and the drying process, this makes thicker plastering once to finish, even under hot conditions, wood fibre also has good thermostability.
Length: 500～1000um.
Polypropylene fibre: polypropylene fibre claims the PP fiber again, have good alkaline-resisting, acid resistance, and use temperature is preferably arranged
The performance bid
Inorganic cementitious material
Mainly contain low alkali cement and ordinary Portland cement, intensity is 32.5R and 42.5R.
Stopping composition
Mainly contain quartz sand: 10～20 orders, 20～40 orders, 40～60 orders, 80～100 orders, 180～200 orders, 325 orders are arranged
