How To Protecting Organic Fiber - Cellulose Fiber from Alkalinity Cement ?

Cellulose Fiber Was Protected with Anti Alkalinity ( MAK-AA ).

Chemically treating cellulose fibers to impart the fibers with hydrophobicity and/or durability, and making cellulose fiber reinforced cement composite materials using the Chemical / Additive MAK-AA treated cellulose fibers which the cellulose fibers are treated or covering / protected with specialty chemicals MAK-AA that impart the fibers with higher hydrophobicity by partially or completely blocking the hydrophilic groups of the fibers.

This technology advantageously provides fiber cement building materials with the desirable characteristics of reduced water absorption of Cellulose Fiber have advantage reduced rate of water absorption which content of Alkalinity components from cement, which was lower water migration will be impacted to lower water permeability so the final products made from these materials have improved freeze-thaw resistance, reduced efflorescence, reduced dissolution and re-deposition of water-soluble matrix components in natural weathering.

Using MAK-AA almost to improve other product properties to the physical and mechanical of final product.

As results of using MAK-AA
i.e the bending strength was increased 10 - 12 % with using 0.05 % of MAK-AA from total weight.
Data was taken from Flat Sheet Calsium Silica Board Product.

MAK- Fiber is 3D-reinforcement solution

What is MAK-Fiber ?
MAK-Fiber is an Organic Synthetic Fiber was applied to Fiber Cement and Board Manufacture which binds with aggregate or filler in mixture components.
MAK-Fiber is creating a highly cohesive 3-dimentional network with enhanced mechanical performance and durability.

Why used MAK-Fiber ?
The use of MAK-Fiber in Fiber Cement or Board can or able to replace Asbestos fiber.
However, it has been clarified that asbestos remarkably injures human health, for example, it causes cancer of the lung and the use of asbestos has been therefore becoming to be legally restricted or prohibited in many countries.

Benefits with MAK-Fiber
Strength without brittleness
The strongly fiber – bound 3D structure and cohesive action of MAK-Fiber allow
+ Cementitious matrix tensile strength due to high fiber elastic modulus.
+ Crack and micro-crack preventive during curing time .
+ Effective bridge mechanism provided the use of fiber with the optimal aspect
ratio ( a very wide range of length-diameter ratios are available)
+ Chemical and mechanical adherence to the cementitious matrix

Thermal and Chemical resistance
MAK-Fiber recognized high resistance to most chemical and physical agents provides a durable reinforcement solution
+ Long term stability
+ Resistance to outdoor exposure ( no rust or UV alterations)
+ Resistance to biological agent ( growth of mildew, fungi,etc)
+ Resistance to cement alkalinity, acids and organic solvents
+ Thermal Resistance

Applications of MAK-Fiber
- Fiber Cement and Board Sheet Manufacture
To replace an asbestos fiber and substitution to cellulose fiber.
Can be applied to both Air Cure and Autoclave Process.
Improves to Strength, Flexibility and Bending of the Fiber Cement and Board
product.
Anti-uv and high temperature , cold resistance ability.
