Non-woven non-woven filled Masterbatch granulator granulator

Non-woven Non-woven Filled granulator granulator one filler dispersion filled masterbatch CaCo3 nonwoven fabric must be uniformly dispersed among the first wetting the surface coated CaCo3 make CaCo3 reducing cohesion between particles and reduce the crushing energy required CaCo3 aggregates, followed by the crushing of CaCo3, through free movement (impact stress) CaCo3 between the particles and the surrounding medium CaCo3 aggregates by shear stress to be reunited broken particles. After CaCo3 refined by dispersing the particle size decreases, the surface area increases, CaCo3 surface free energy also increased refinement of CaCo3 caused instability, so CaCo3 surface coating process to further reduce the interfacial surface of the newly formed You can prevent the re-aggregation, and then mixed and dispersed in the melt CaCo3 upcoming wetting and crushed CaCo3 distributed evenly dispersed meltblown nonwoven spunbond in need. Second, the performance requirements of non-woven fabric mother filled polypropylene PP is a pure hydrocarbon molecular chain containing a tertiary carbon atom, heat, by light punishment in tertiary carbon atoms child easily cleaved so that the meltblown nonwoven spunbond quality deterioration, so the requirements made of non-woven fabric with a filler in high-temperature spinning easily diffuse, without damaging the fiber quality, withstand rigorous spinning draft. (1) Heat resistance; nonwoven fabric filler with the basic requirement of polypropylene to withstand temperatures during fiber production, to maintain its stable performance. Spunbond temperature is 270 ~ 280 ℃, meltblown stability of 270 ~ 300 ℃. (2) dispersion; non-woven fabric filler should be good dispersion, and dispersing agent used will not reduce the quality of spunbond meltblown nonwoven fibers. Or can not produce a good quality fiber fineness uniform melt motion is not stable, easy to break the fibers during drawing or abnormal fibers. (3) Stability; nonwoven fabrics filled masterbatch CaCo3, for spunbond meltblown nonwoven fibers have excellent stability. Particle size distribution, without a particle size of 20 microns or larger impurities, meltblown nonwoven spunbond ensure excellent physical properties of the fiber.
