PP FiberPP MONOFILAMENT FIBER
PP-Fiber, is also called engineering fiber、concrete fiber、anti-crack fiber、crack control fiber、synthetic fiber or plastic fiber,etc.It is a kind of high intensity bunchy monofilament fiber mainly made of PP by special technique. Put PP-fiber into the concrete or mortar, can effectively prevent temperature change, microcrack caused by plastic and dry shrinkage,etc, thereby prevent and control the happen and development of crack and improve effectively anti-crack、anti-infiltration、anti-concussion and anti- shock of the concrete. It can be divided into insulation motar crack resistant polypropylene fiber and Special polypropylene fiber for cement concrete Insulation motar crack resistant polypropylene fiber
Insulation motar crack resistant polypropylene fiber according to the characteristics of the fiber insulation mortar, on the basis of the traditional production process, by the formulation of the adjustment process, the fibers of a special anti-static and anti-UV treatment, the fiber is uniformly dispersed in the mortarcan further improve the strength and toughness of the mortar, and greatly changed the mortar cracking itself, intolerant red, do not wear the weakness of a thorough solution to the fiber difficult to disperse in the mortar, the problem of poor adhesion. FirstPhysical properties and main technical parameters
SecondMain advantages
good dispersion,high toughening;
2. good cracking and permeability resistance 3.stable performance, safety and environmental protection;
4, easy construction, economical and reliable. ThirdThe main function 1、anti-crack function In the mortar, the chaos of the fiber distribution patterns can greatly help to weaken the mortar plastic shrinkage and freeze-thaw stress, contraction of the energy is dispersed into single fibers per cubic meter of ten million, which is extremely effective enhancedthe toughness of the mortar, and inhibited the emergence and development of micro-cracks.
2、Improve the water impermeability of mortar Uniform fiber distribution a large number of fibers interlaced with each other in the mortar has played the role of "supporting" the aggregate, reduce the segregation of the mortar surface analysis of water and aggregate to surface mortar, adhesive mortar, the particles of polystyrene wall insulation mortarbasement works with fiber waterproof materials the effect is particularly significant, which can effectively solve the penetration problem troubled. 3、the improvement of toughness and anti-shock Fiber can help to absorb the kinetic energy ,which produced when the component of concrete is shocked, moreover due to the anti-crack effect of the fiber, when the concrete is shocked, the fiber can prevent the rapid extend of the inner crack, consequently increased the toughness and anti-shock of the concrete. Fourth Amount of fiber mixing Mixing amount of ready-mixed mortar cracking fiber：0.9~1.8kg/m³,General mixing amount:1.2kg/m³；
Surface mortar cracking fiber mixing amount：0.6~1.83kg/m³,General mixing amount:0.9kg/m³； Engineering geographical and different parts of the fiber content should be different, more serious for the freezing and thawing of a relatively large geographical and punch grinding site should be appropriate to increase the dosage is appropriate. fifthUsage To ensure that the fibers in the mortar is mixed thoroughly, to ensure that each tank mortar mixing time Construction in the rainy season, the mortar to avoid the rain soaked and washed, otherwise it will affect the results. sixthSpecfication and Package Specfication：PPF-RY3、6、10、12 Package： 0.6kg/plastic bag、0.9kg/ plastic bag、1.0kg/ plastic bag，18或20kg/woven bags。
Special polypropylene fiber for cement concrete Special polypropylene fiber cement concrete is one of the organic synthetic fiber used for civil engineering, mass concrete and concrete structures can be used as cement concrete secondary ribs. Plastic shrinkage of polypropylene fiber by adding cement concrete, which can effectively control concrete shrinkage, micro-cracks caused by temperature changes and other factors to prevent and suppress the formation and development of cracks. Improve long-term concrete performance, increase the deformation capacity and durability, the other can greatly improve the one-time injection of sprayed concrete thickness, strength and reduce the spring rate, so that the concrete has a good integrity. Thus been widely used in transportation, housing construction, airports, military, water conservancy projects.
