High Quality Engineering Fiber
Product Description
S.F. Build-fiber is now widely used in concrete/cement
mortar/cementitious plastering material in the world. It can remarkably
modify its splitting resistance, barrier property, shockproof property
and resistance to impact, and takes effect in reinforcing, firm and
durability. It is a kind of high tech. and new type building material
that it can take very important effect in building engineering.
As far back as 1970s, some developed countries, such as the USA, UK,
Canada, came to research the synthetic fiber for building, latter
achieved commercialized production. With widely blending fiber into
concrete/cement mortar for several ten years, the all test reports show
that the engineering qualities are improved in diversified building.
First, the splitting resistance was improved and the crazing index was
greatly reduced; the second, barrier property was improved, primarily
control the water permeability; the third, the resistance to impact was
increased by 3-4 times, the fastness of concrete was greatly improved;
the fourth, the toughness was obviously improved and the bending
strength was greatly improved.
In the 1990s, Durafiber (US) came into our country and applied in key
building engineering. Now, the fiber has been well received by the
building industry of our country. But it is impossible to use it on a
large scale because of its high price.
For realizing the new type building fiber made in our country, reducing
greatly engineering costs and meeting the development demands in our
building field, our company had developed S.F. Buildfiber successfully
in 2002, and it has formed the capability of producing 5000T this kind
of fiber a year. The products is made of PP/PE/PET and spun in
particular process. After its surface coated with activation, it
possesses the merits as follows: good acid and alkali resistance and
resistance to ageing, high elastic modular, excellent dispersion
quality, low density, and so on. The product does not join together,
distributes evenly in concrete and has good affinity for cement and
preserve moisture. Alll of the targets of the fiber reach the standard
of the same kind product made in foreign countries.

The test of acid-alkaili resistance is according to the relate standards of glass fiber 1.The strength of S.F. fiber is hardly lost after soaking in sodium hydroxide (5%, 23C) for 28 days; 2.The strength of S.F. fiber is hardly lost after soaking in sodium hydroxide (5%, 80C) for 6h. The applied field of S.F. fiber * The concrete road, airfield running road and parking apron * Irrigation works, waterproof works underground and sewage farm * The highway, tunnel of railway, underground engineering * Bridge works, crossroads, the pavement of trestle and guardrail * The houses, the concrete of toilet and cement mortar for stuccoing * The cement mortar/cementitious plastering material for decorating and cement mortar for keeping warm
