Powdered Cellulose

01 Overview

Powdered cellulose is a powdered additive for chemical building materials products, manufactured by processing wood pulp. It is a naturally occurring fiber insoluble in water, exhibiting excellent flexible strength, dispersibility, and chemical inertness. Powdered cellulose is environment friendly products, gained from replenishable raw materials.

Powdered cellulose is a fibrous additive that extracted from wood pulp and through chopped, neutralized, bleached, crushed and sieved into finished products with different lengths and thicknesses to suit the needs of different materials and formulations. It can be mixed with powder materials such as cement, gypsum and lime to improve the resistance of cracking, water retention and resistance of shrinkage.

Powdered cellulose and hydroxypropyl methylcellulose are two different products. Powdered cellulose is a water-insoluble natural fiber, which is essentially different from hydroxypropyl methylcellulose. Although certain functions of wood fiber, such as thickening and water retention are similar to that of  hydroxypropyl methylcellulose, their thickening and water retention effects are much lower than those of hydroxypropyl methylcellulose and cannot be used as a thickener and water retention agent individually. The biggest role of Lignocellulose is the flexibility of the material itself, and its anti-hanging property.

Powdered cellulose has been widely used in dry mortar, such as the production of tile adhesive, crack-sealer, dry powder coating, interior and exterior wall putty, interface agent, thermal mortar, anti-cracking mortar, waterproof mortar and plastering anhydrite.

Because Powdered cellulose has good property of flexibility and dispersibility, adding appropriate amount of wood fiber with different length into dry mortar product can enhance the resistance of shrinkage and crack to improve the thixotropy and sag resistance of the product and prolong the opening time and play a certain thickening effect.

02 Questions & Answers

  1. 1
    Overview of Powdered Fibre

    Powdered fibre is an organic fibre derived from natural timber through chemical processing. It typically exhibits a cotton-like appearance, appearing white or greyish-white in colour. This fibre finds extensive applications across multiple sectors, such as road surfacing, concrete reinforcement, and fire-retardant coatings. Owing to its unique physical and chemical properties, Powdered Cellulose has become a vital component in modern building materials.

    Production Methods for Powdered Cellulose

    The production process for Powdered Cellulose involves several key steps. Firstly, high-quality timber such as pine or birch is selected as raw material. The wood is then cut and pulverised into wood chips. Chemical treatment, typically using alkaline solutions, removes lignin and other impurities from the wood.Finally, the treated wood pulp undergoes fibrillation to yield the final cellulose fibres. Precise control of conditions throughout this process is essential to ensure fibre quality and performance.
    Furthermore, during Powdered Cellulose production, subsequent treatments such as bleaching, drying, and shaping may be applied as required to meet diverse application needs. These processing steps can further enhance the fibre’s whiteness and purity while improving its physical and chemical properties.
