Description

Introduction of Lignin Fiber

Lignin fiber is an organic flocculent fiber obtained by chemical treatment and mechanical processing of natural renewable wood. It can be widely used in asphalt roads, concrete mortar, gypsum products, wood pulp sponge and other fields. It can also be used to manufacture medium-density fiberboard and home building materials.

Product Function of Lignin Fiber

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, which greatly improves the accuracy of construction or prefabricated parts.

2. Lignin fiber has strong antifreeze ability.

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

4. The dimensional stability and thermal stability of lignin fiber determine the excellent insulation and crack resistance effect. The water transmission function of lignin fiber makes the slurry surface and the base interface hydrated sufficiently, thereby improving the surface strength of the insulation material, the bonding strength with the base and the uniformity of the material strength.

Usage Method of Lignin Fiber

Product Dosage:

1. Asphalt dosage: Under normal circumstances, the recommended amount of lignin fiber is 0.3% of the total mass of asphalt mixed aggregate. The specific amount of addition should be carried out 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. Internal and external wall putty powder: generally add 0.3-0.5%.

4. External insulation mortar: generally add 0.5%.

FAQs of Lignin Fiber

Q: What are the main sources of lignin fiber?

A: Lignin fiber primarily comes from the pulping process of wood, where it is separated from cellulose. The two main methods of pulping include the kraft process and the sulfite process. Other potential sources include agricultural residues like corn stover, sugarcane bagasse, and rice husks.

Q: How does lignin fiber compare to synthetic fibers?

A: Compared to synthetic fibers, lignin fibers are generally less expensive and more environmentally friendly due to their renewable nature and biodegradability. However, they may have lower performance characteristics in terms of tensile strength and consistency compared to synthetic counterparts like polyester or nylon.

Q: Is lignin fiber sustainable?

A: Yes, lignin fiber is considered sustainable because it is a byproduct of the paper industry, meaning its production does not require additional resources beyond what is already being used to make paper. Additionally, it is biodegradable and derived from renewable resources.

Q: Can lignin fiber be modified?

A: Yes, lignin fiber can be chemically modified to alter its properties, such as improving its dispersibility in water or enhancing its bonding capabilities with other materials. These modifications can expand its range of applications and improve its performance in various products.
