With the rapid development of economy and urban construction and enlarged
scale of industry and construction, the requirement to the technical disposal
of building surfaces is much higher than before.
On the basis of improving body's engineering design and constructing quality.
Improving the surface quality, like roof of building and wall and floor, becomes
a crucial task to the construction field. So on the basis of successfully developed
polypropylene fiber for concrete and polyester fiber for bitumen and in view
of some technical problems existing in constructing field, we sums up experiences
and develops cracking-resistance reinforced fiber for cement paint (using in
plastering).
These fibers can improve quality of building's wall and flooring, and supply a new
technical measure to reduce the surface crack, so it has a good economic value.
Functions:
1) Resists to shrink and crack
2) Increases seepage resistance
3) Increases friction resistance
4) Increases freezing and thawing resistance
5) Improves tendons protection
6) Replaces steel net (using in plastering)
7) Prevents mortar split and crackle expansion
8) Increases impact resistance and peeling resistance
Features of polypropylene monofilament:
1) No agglomeration and easily spreads around in mortar or concrete,
guaranteeing the property of crack resistance effectively
2) Convenient applying: no need to change the proportion of mortar, and
just put the fibers into the mortar mixture and stir for a moment after
adding water
3) Fine economic property: the equivalent diameter of polypropylene
monofilament is only 0.02mm, so the ratio of diameter and surface is high
and on the basis of crack resistance, it can reduce the amount (0.6kg/m3)
and cut down the cost effectively
4) Be better to plaster: because a great number of thin fibers spread into
mortar evenly, so the plastering is much easier and this can improve the
binding strength between surface and base
5) The fiber has stable chemical property, strong acid and alkali resistance,
and can be used in any engineering projects
Suitable engineering for polypropylene monofilament:
1) Be suitable for the waterproof layer, floor, inner / outer wall of industrial
and construction
2) Increases cracking resistance on the surface of industrial workshop,
warehouse and parking lot
3) Increases cracking / seepage resistance of the ground in natatorium,
swimming pool, pond and ditch
4) Be suitable for any mortar projects and fine aggregate concrete projects
Application instructions:
1) Compound amount: to resist the common cracks on surfaces, 0.6kg/m3
fibers to cement paint are enough, and for reinforced application
0.9-0.8kg/m3 are enough
2) Stirring requirement: the proportion of cement, sand and aggregate is
no need to be changed. Put cement, aggregate, additive and fiber together,
then stir after adding enough water (do not stir without water) and time
for stirring can be prolonged for 2- 3 minutes in order to make the compound
mix completely
