lignin fibre (construction) - GW

Lignin fiber(building) is widely used in the construction industry, such as production of tile adhesives, grouts, powder coating, wall putty, interface agent, insulation mortar, cracking plaster mortar, waterproof mortar and stucco plaster. Lignin fibers easily dispersed in the insulation material to form three-dimensional results, and can absorb 6-8 times the weight of water. This structure and improve the workability of the material characteristics, performance and operating performance, anti Huazhui performance, speed up the construction speed; wood fiber dimensional stability and thermal stability of the insulation material insulation cracking played a good role; Wood transmission fiber slurry surface water features make adequate hydration reaction with the primary interface, thereby increasing the surface strength of insulation materials, with the primary bond strength and material uniformity. These properties make the wood fibers in the insulation material to become an indispensable additive.

Physical parameters

Mechanism:

Strongly enhanced thickening effect:

Wood fibers crosslinked with a strong function, which after mixing with other materials, like a bonding between the fibers at once, like a blanket, this three-dimensional structure can be water or other liquids locked in the meantime, the longer the fiber, the greater thickening effect.

Wood fiber can improve performance structural viscosity:

When the shear force of its time (such as scraping, mixing, pumping), part of the liquid from the fiber structure matrix apparently succumbed, leading to lower viscosity, improve workability. When the shear is stopped, the fiber structure is very quickly restored moisture absorption and come back and restore the original viscosity.

Good liquid forced adsorption force:

Wood fiber can absorb its own weight of 100% -200% of the liquid. And using the structure of 2-6 times the weight of liquid absorption.

Crack resistance:

Curing or drying process in the mechanical fiber reinforcement can be weakened. Low shrinkage: wood fiber is very good dimensional stability, which means that the settlement does not occur mixture contraction and increase its resistance to cracking.

Anti-fall:

Construction operation and the drying process does not appear to fall phenomenon, which makes a thick plaster can be completed, even in high temperature conditions, the wood fibers also have good thermal stability.

Extended opening hours:

Capillary action of the fiber structure of the water from the internal surface of the slurry rapidly and transmitted to the interface, making the slurry uniform moisture distribution within the system, can significantly reduce the crust and makes bond strength and surface strength was improved, this mechanism also because of reduction of tension in the drying process and significant role to
