Lignin fiber (Methyl Cellulose, referred to as MC) is a chemically
treated wood are natural organic fibers. Through the screen, split,
high temperature treatment, bleaching, chemical processing, and,
screening into different length and thickness of the fiber
materials to adapt to the needs of different applications. As the
treatment temperature of 260or more, under normal conditions is
chemically very stable material, not with the usual solvents,
acids, alkali corrosion, using natural raw materials to produce the
lignin fiber is non-toxic, tasteless, non-polluting,
non-radioactive good quality, a green product, which is the other
mineral fibers do not have impact on the environment, so harmful to
humans, is conducive to environmental protection.

Lignin role of fiber in building materials:
Wood fiber insulation materials easily dispersed in the formation
of three-dimensional results, and can absorb 6-8 times the weight
of water. And characteristics of this junction to improve the
workability of the material properties, operational performance,
anti Huazhui performance, speed up the construction speed; wood
dimensional stability and thermal stability of fibers in the
insulation material has played a very good insulating concrete
cracking; wood the transmission fiber slurry water features make
the surface of adequate hydration reaction with the primary
interface, thereby increasing the surface strength of insulation
materials, and grass-roots strength of the bond strength and
material uniformity. These properties make the wood fiber in the
insulation material to become an indispensable additive. 1. A strong thickening enhancement:
Lignocellulose with a strong cross-linking darn function, it mixed
with other materials between the fibers into a three-dimensional
structure of overlap can be water locked in the meantime in order
to maintain water retarding, water reducing effective cracking it.
2. To improve performance:
When the shear force of its time (such as mixing, pumping), part of
the structure of the liquid flung from the fiber matrix, lead to
lower viscosity, improve workability, when the flow stops, the
fiber structure is very rapid recovery moisture absorption and
back, and restore the original viscosity.
3. Crack resistance:
In the freezing or drying process the mechanical fiber
reinforcement can weaken, to prevent cracking.
4. Low Shrinkage:
Biological dimensional stability of wood fiber is very good
settlement mixture contraction does not occur and to increase their
crack resistance.
5. A good adhesive force to force the liquid:
Wood fiber itself can absorb 6-8 times the weight of the liquid,
and 6-10 times using the structure of liquid absorption.
6. Against falling:
Construction operation and the drying process does not appear to
fall phenomenon.
