Works with polypropylene fiber engineering, based on polypropylene as raw material, manufactured by special process. Incorporated polypropylene fibers project to improve the quality of concrete, comprehensive performance is improved. Having a mixing process is simple, inexpensive and excellent performance characteristics. Let's go look at the process steps for making polypropylene fibers.
1, polypropylene fiber works on a per-mixed concrete volume side, in accordance with the requirements of mix (or suggested content) accurately measure the weight of each fiber added.
2, sand and gravel ready after the fibers are added. Recommended compulsory mixer. The aggregate together with the fibers added to the mixer. It should be noted should ensure that fiber is applied between the aggregate dry mix for about 30 seconds after the addition of water, wet mix about 30 seconds, so that the fibers sufficiently dispersed.
3, after the completion of the stirring random sampling, such as fibers have been uniformly dispersed into a single wire, the concrete can be put into use, if the fiber bundles are still extended mixing time 20-30 seconds, can be used.
4, with the addition of fiber concrete and ordinary concrete curing process are identical.
