Cellulose fiber is a nature-derived material. It is applicable to both construction mortar and skin-friendly fabrics. With its distinctive characteristics, cellulose fiber stands as a crucial bridge linking nature and industry. From traditional wood pulp extraction to modern bio-based technological innovations, the application boundaries of cellulose fibers have been continuously expanded, especially in the waterproofing field.
First, Origin: The "Fiber Elf" from Nature
The essence of cellulose fiber is a natural polymer compound extracted from plants, with raw materials widely distributed in nature—wood, bamboo, cotton linters, and even the "happy grass" mentioned in the TV drama Minning Town. This nature-derived attribute endows it with inherent environmental advantages: biodegradable and renewable, perfectly aligning with the current global trend of green development. Longou Chemical's cellulose fiber series is made from natural wood through professional processes, ensuring compatibility with various building materials while meeting green building standards.
Second, Core Value: Synergistic Effects in Powder Waterproof Agents
In the fields of architectural waterproofing and textile waterproofing, cellulose fibers can form a synergistic system with powder waterproof agents, significantly enhancing product performance. Particularly in architectural mortar waterproofing, the water-retention and crack-resistant properties of cellulose fibers perfectly complement the hydrophobic and corrosion-resistant functions of powder waterproof agents, solving many architectural challenges.
1. Water Retention & Thickening: Optimizing Waterproof Agent Dispersion
During construction, if mortar dries too quickly, it will lead to reduced adhesion and uneven finishing. Cellulose fiber, however, exhibits strong hydrophilicity, capable of absorbing 6-8 times its own weight in water. It can lock in moisture within the mortar, ensuring the material maintains a good workable state even in hot or arid environments. More importantly, this water-retention capacity helps powder waterproof agents disperse evenly in the mortar matrix, preventing agglomeration and ensuring consistent waterproof performance. Note that damp cellulose fibers or insufficient mixing can cause uneven dispersion of the waterproof agent, resulting in local waterproof failure.
2. Crack Resistance & Reinforcement: Protecting the Waterproof Barrier
Mortar structures are prone to shrinkage cracks, which become channels for water penetration and damage the building's waterproof barrier. The unique physical structure of cellulose fibers enables them to form a three-dimensional network reinforcement scaffold when dispersed in cementitious materials. This scaffold can promptly bridge initial microcracks, prevent crack propagation, and thus protect the hydrophobic layer formed by the powder waterproof agent. In harsh environments such as coastal areas and marine settings, this crack-resistant feature is particularly critical—it can work with specialized powder waterproof agents for ship hulls to inhibit seawater penetration through cracks, delay chloride ion corrosion of hull structures, and extend the service life of ships.
3. Enhancing Rheological Properties: Improving Construction Performance
Cellulose fibers improve the rheological properties of mortar and cement by reducing segregation and bleeding, making construction smoother, pumping easier, and finishing more uniform. Longou's ECOCELL® GSMA cellulose fiber, specially designed for asphalt macadam pavements, enhances cohesion, reduces rutting, improves skid resistance, and maintains excellent workability during paving. In external wall insulation systems or masonry mortar, this rheological control ensures tight bonding between the material and the substrate, reducing the risk of peeling.
