I. Product Description Introduction
The fiber is based on polypropylene as a raw material, after special modification and corrugating process after processing. It has the advantages of acid and alkali resistance, high strength, easy dispersion, easy construction, no damage to the vehicle and road surface after being added, and no need for special maintenance. It can replace steel fiber for strengthening crack prevention in cement concrete, and because of special The corrugated cross-section shape has good bonding properties with concrete and strong grip.
Second, the main performance indicators Specification

Third, the instructions for use Applying Instruction
1. Dosage: 3kg per cubic meter of concrete
2, the length of choice: General enhanced cracking 50mm, shot concrete 19mm
3, sleep ratio design: Under normal circumstances, do not have to change the grade ratio parameters of concrete. Taking into account the anti-crack performance requirements of concrete, can be used in proportion to the volume ratio of 1:1 and polypropylene mesh fibers (each side of concrete mixed with 0.9kg mesh fibers).
4. Mixer selection: Use a double-shaft horizontal type forced mixer.
5, feeding mixing process: first put into the gravel, and then put the fiber, and then put into the sand and stir for 2 minutes, so that the fiber is fully open, and then into the cement and water can be mixed according to the conventional process. It can also be constructed in the order of conventional process inputs, but the mixing and stirring time should be not less than 4 minutes, and the vibrating time should be appropriately extended to allow the fibers to mix thoroughly.
6, forming maintenance: no special requirements, you can extend the tap time as appropriate, about 30 seconds, wipe the surface should be slightly after the passivation of the concrete surface, so as not to bring out the fiber, maintenance should still be carried out according to the requirements of ordinary concrete.
7. Packing form: 1.5kg/bag, can be subcontracted according to user's requirements
Fourth, Economic Economy
Compared with steel fiber, plastic wave fiber has the advantages of corrosion resistance, less wear, and 50% reduction in the same volume volume price.
