What are the points of attention when applying polypropylene engineering fibers?
1. Application of polypropylene engineering fibers: all kinds of ready-mixed mortar, such as: leveling mortar, plastering mortar, insulating mortar; masonry mortar, caulking putty, exterior wall coating, etc.
2. The amount of polypropylene engineering fibers: the use of polypropylene engineering fiber generally does not need to change the original design mix ratio. The general dosage per cubic meter of mortar is 0.9-1.5Kg, and the recommended dosage is 1.0Kg per cubic meter of mortar.
3. Note: The fiber is only used for crack resistance. After blending, the addition amount of various other additives in the original mortar mix ratio cannot be changed.
Input and agitation: polypropylene engineering fibers are mixed with cement and sand, and the fiber should be floated at the top for a little longer.
4. Strength test: The addition of polypropylene engineering fibers generally does not affect the strength of the structure, but the mixture should be verified by experiment before each project is used for the first time.
5, the work pressure surface: mortar should be used as much as possible to use steel or iron trowel, wooden trowel is not smooth enough, will hook out the fiber.
