NATURAL FIBERS -as Subtitute for Asbestos

How strong this fiber ?  book weight is 380 gram

Sisal fibre is obtained from Agave sisalana, a native of Mexico. The hardy plant grows well in a variety of hot climates, including dry areas unsuitable for other crops. After harvest, its leaves are cut and crushed in order to separate the pulp from the fibres. The average yield of dried fibres is about 1 tonnes per hectare, although yields in East Africa reach 2.5 tonnes.

The fibre

Lustrous and creamy white, sisal fibre measures up to 1 m in length, with a diameter of 200 to 400 microns. It is a coarse, hard fibre unsuitable for textiles or fabrics. But it is strong, durable and stretchable, does not absorb moisture easily, resists saltwater deterioration, and has a fine surface texture that accepts a wide range of dyes.

Uses of sisal

Sisal is used in twine and ropes, but competition from polypropylene has weakened demand.

 

But other markets are emerging - today, sisal can be found in speciality paper, filters, geotextiles, mattresses, carpets and wall coverings.

 

It is used as reinforcement in plastic composite materials, particularly in automotive components, but also in furniture. Another promising use is as a substitute for asbestos in brake pads. (It is also the best material for making dartboards.)

By-products from sisal extraction can be used for making bio-gas, pharmaceutical ingredients and building material

WHITE ASBESTOS ( CHRYSOTILE) IT'S STILL A KILLER ?

Please see to Caution or Danger of this products

Please take care in safe on handling process

Mining companies argue that the body can clear chrysotile asbestos fibers from the lungs and that as a result, chrysotile asbestos poses no health risk. In a paper titled "Undeniable Facts about Chrysotile," its proponents claim that not only does chrysotile have less risk than other forms of asbestos, but also that at low exposure levels, it produces no risk at all. Doctors and scientists counter with the statement that all forms of asbestos cause cancer. According to Mesothelioma.com, a site about asbestos-related cancers, doctors say no amount of asbestos of any form is safe. In 2007 Occupation and Environmental Medicine published a follow-up study of chrysotile asbestos textile workers in South Carolina. The doctors and researchers concluded that the study confirmed the findings from previous investigations of increased risk of death from lung cancer and asbestosis and a strong correlation between exposure to chrysotile and mortality from lung cancer and asbestosis

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.

AUTOCLAVE

Autoclave is one of part the key equipment in the production of Calsium Silica Board or Fiber Cement Board.

Autoclave is a principle and cylindrical device made of steel, and has the advantages of good quality and reliable performance.

Purpose of Autoclave
The autoclave is applicable for curing the green sheet / Plat Sheet or Roofing Corrugating under high temperature and high pressure, and is also applicable for curing the autoclaved brick or AAC ( Light Concrete ) under high temperature and high pressure.

Structural Features of Autoclave.
Autoclave is a principle and cylindrical device made of steel, the cover is made of a whole piece of pressed 16 Mn steel board, and the flanges of cover and body adopt a whole piece of forged and processed 16 Mn steel board. The welding lines of pressed components are subjected to heat treatment and strict non destructive test.

The max design pressure reaches 1.65-1.8 Mpa ( operation condition ).
