lignin fiber

lignin fiber is an organic flocculent fiber material obtained by chemical treatment and mechanical processing of natural renewable wood. It is widely used in asphalt roads, concrete mortars, gypsum products, wood pulp sponges and other fields. It can be used to make MDF and used in the home building materials industry.

Technical Parameters

Product Features

1. The structural viscosity of lignin fiber keeps the processed prefabricated slurry (dry and wet materials) stable and reduces the shrinkage and expansion of the system, greatly improving the accuracy of construction or prefabricated parts.

2. Lignin fiber has strong antifreeze ability.

3. Lignin fiber is easy to disperse, forms a three-dimensional space effect in the insulation material, and can absorb 6-8 times of its own weight in water. This feature improves the material's workability, operability, anti-slip performance, and speeds up construction.

4. The dimensional stability and thermal stability of lignin fiber determine the excellent thermal insulation and crack resistance effect.

5. The moisture transmission function of lignin fiber enables sufficient hydration reaction at the interface between the slurry surface and the base layer, thereby improving the surface strength of the insulation material, the bonding strength with the base layer, and the uniformity of the material strength.

Areas of application

1. Asphalt roads, highways, bridge deck paving, airport runways and other projects.

2. Exterior wall insulation mortar, mineral mortar, wall mortar.

3. PVC filtered, water-resistant putty powder.

4. Relief paint, interior and exterior wall paint.

5． Tile adhesive.

6. Gypsum products, building wall panels, countertops, etc.

7. Precast parts: concrete precast parts, pipes, plates.

8. Wood pulp sponge, compressed sponge

Application areas

Product dosage:

1. Asphalt dosage: Under normal circumstances, the addition amount of lignin fiber is recommended to be 0.3% of the total mass of asphalt mixed aggregate. The specific addition amount must be implemented according to the engineering design dosage and added accurately.

2. Concrete dosage: 1-2 kg/m³, concrete with special requirements can reach 15kg/m³.

3. Interior and exterior wall putty powder: generally add 0.3-0.5%.

4. External insulation mortar: generally add 0.5%.

Construction technology: The gap type mixer adopts manual feeding. Continuous mixers can use fiber feeders.

Packaging and storage

Packaging: woven bags or cartons 10kg-20kg per large package, can also be produced and packaged according to user requirements.
