Installation and Usage Instructions

The usage of wood cellulose fiber varies by application. Here’s a general guideline:

For Composites or Polymer Reinforcement:

1. Drying: Ensure fiber moisture content is below 8% to prevent matrix defects.

2. Dispersion: Mix fibers uniformly in the polymer matrix to avoid clumping.

3. Processing Temperature: Keep below 200°C unless fibers are chemically modified for higher heat resistance.

4. Additives: Use coupling agents (e.g., silanes, maleic anhydride) for improved polymer adhesion.

For Cement and Mortar Reinforcement:

1. Dosage: Typically 0.5 – 2% by weight of cement for optimal performance.

2. Mixing: Blend evenly with dry cement before adding water.

3. Curing: Standard curing methods apply; fiber aids in crack resistance.

For Paper and Packaging:

1. Pulping: Incorporate into wet pulp mixture for even distribution.

2. Sheet Formation: Follow conventional papermaking techniques.

3. Drying and Pressing: Standard drying temperature; fibers enhance strength without affecting texture.

For Textiles and Non-Woven Fabrics:

1. Blending: Combine with other fibers (cotton, synthetic) as needed.

2. Carding and Spinning: Ensure uniform fiber orientation.

3. Fabric Formation: Non-woven mats or woven structures as per application.

Maintenance and Storage

• Storage Conditions: Keep fibers in dry, cool conditions (<25°C, <60% humidity) to prevent mold or clumping.

• Shelf Life: Typically 6 – 12 months under proper storage.

• Handling: Avoid excessive moisture and compression to maintain fiber integrity.

• Transportation: Pack in sealed, moisture-resistant bags to prevent contamination.
