Description
Construction cellulose fiber
Construction cellulose fiber can easily disperse in the thermal insulation material and form three dimensional space, and it can absorb water 6-8 times than its own weight. This character of combination improves operating performance, anti-sliding performance of the material, and speeds up the construction progress.
Application of cellulose fiber in the field of construction
Viscosity reduces with the increase of sheer rate (pumping, mixing, construction) Low sheer rate will result in increasing of viscosity immediately. Under stationary state, the viscosity will back to original.
The gelled system depends on the length of the fiber. The longer the fiber, the more obvious the thickening effect.
The cross-linking system formed through the establishment of three-dimensional fiber skeleton to make the cellulose fiber gain higher stability.
Filling in the joint prats and the cracks enhance closing cracks effect.
Cellulose fiber in many applications plays a role of anti-cracking.
Due to the extended opening times,cellulose fiber can reduce the formation of skin.
On the strong absorption level,cellulose fiber still has a good operating performance.
It can put the remaining water within the capillary of fiber and make the freezing point down to -70 degree.
Recommended dosage:
| Thermal insulation mortar | 0.4-0.5% | per ton |
| Tile adhesive | 0.3-0.5% | per ton |
| Insulation mortar layer | 0.2-0.3% | per ton |
| Caulking agent | 0.4-0.5% | per ton |
| Exterior wall putty | 0.3-0.5% | per ton |
| Gypsum plaster | 0.2-0.4% | per ton |
Application of cellulose fiber in mortar:
1. Insulation mortar
Cellulose fiber can easily disperse in insulating material and form three-dimensional space, and it can absorb water 6-8 times of its own weight.This character of combination improves operating performance, anti-sliding performance of the material, and speeds up the construction progress. Cellulose fiber's dimensional stability and heat stability in insulation material plays a crack resistance function in insulation. The moisture transmission function makes the slurry surface and the basic interface hydration reaction, which improve the surface strength of the insulation material, the strength of the adhesive and the strength of the material uniformity.
2. Tile adhesive
Cellulose fiber can improve the construction performance, significantly reduce the adhesion of construction tool and improve the slip resistance and water retention of the tile adhesive. It can also extend the opening time and improve the wetting properties,then reduce cracking.
3. Self-leveling ground material
Cellulose fiber can increase the viscosity and be used as anti-precipitation agent. Enhance liquidity and pumping ability, improve the efficiency of the flooring. The controlling of water retention greatly reduce the tearing and shrinkage.
4. Bonding mortar
Cellulose fiber strengthen the adhesive properties and water retention and strength of mortar. It can also increase the lubricity,plasticity, construction performance, save time and improve cost-effectiveness.
5. Tile sealant
Cellulose fiber's good water retention can extend the cooling time to improve the work efficiency. Its high lubricity makes the construction easier and more smooth to improve the anti-shrinkage and anti-cracking resistance and product's smooth and uniform characteristic and stronger adhesion on the surface of the joint property.
6. Paint coating and asphalt materials
Cellulose fiber can improve asphalt pavement's adhesion,temperature stability and durability. It can also effectively improve the tensile ,crack resistance and impact strength.
7. Gypsum-based plaster and gypsum products .
Cellulose fiber make the mortar easier conducting and improve the ability of sagging, enhance the liquidity and the pump,and improve working efficiency.Then high water retention can extend opening time of mortar and form high mechanical strength during solidification period.
8.Seepage control and crack resistance of concrete
Concrete cause cracking and leakage,then reduce the durability of concrete and internal reinforcement corroded, affecting the service of engineering.Using cellulose fiber can improve the percolating proof properties of concrete.
9. Cement-based plastering mortar
Cellulose fiber make the mortar easier conducting and improve the ability of sagging, enhance the liquidity and the pump,and improve working efficiency.
High water retention can extend opening time of mortar and form high mechanical strength during solidification period.
Controlling the mixing of air can eliminate the micro-cracks of coating, and form ideal smooth surface.
10. Building waterproof mortar
Cellulose fiber can effectively fill the defects of structure of waterproof, roofing engineering and other modern engineering and other modern engineering technology innovation application and development of technical performance defects.
