Characteristics of functional masterbatches
Particle size:
　　Granular solid particle diameter of 0.1~3mm is composed of the powdered solid. 0.1mm (100 m) for particles of powder; 1~10 m for fine powder; 0.1~1 mu m ultrafine powder; "3mm particles for crushing solid block. The smaller the particle size, the more dense the obtained mixture. But the same solid particle size is smaller, more easily with each other between the particles adsorbed cluster, the cluster, in the mixed with another kind of solid particles is not easy to open, in the plastic melt is also difficult to disperse.
The particle size distribution:
　　Powder material filling of wide size distributions than the narrow particle size distribution is more compact. Because the small size can enter the gap among the particles to go in, but will be two kinds of particle size difference of powder in mixed, it is difficult to get uniform.
Function masterbatch hardness:
　　The surface of powder particles, ceramic powder, inorganic antibacterial agent, the hardness is too high will cause the quartz sand mixing equipment of serious wear and tear, not only reduces the service life of equipment, and allowing the mixture to the dark color, gray hair, serious when direct black.
Function masterbatch composition
The main composition of filler masterbatch:
1). Packing: such as calcium carbonate. The talcum powder.
2). Coupling agents: such as carbonate silane.
3). Dispersing agent: such as polyethylene wax and stearic acid salt.
4). The carrier resin. The hygroscopic defoaming masterbatch moisture defoaming masterbatch is composed of metal oxide + resin + additives. Flame retardant masterbatch flame retardant masterbatch is composed of flame retardant + resin + additives. Conductive masterbatch conductive masterbatch will long copper fiber and resin, coating and pelleting complete. Foaming masterbatch foaming masterbatch is composed of composite foaming agent, lubricant, dispersing agent, colorant, anti ultraviolet mother grain anti ultraviolet masterbatch with two kinds of anti UV agent compound, with carrier, dispersing agent and made of. Weather weather masterbatch masterbatch is composed of light stabilizer + resin + additives.
The role of functional Masterbatch
　　Cooling masterbatch is mainly used for PP probably can drop the temperature of 30-50 degrees. Brightening masterbatch masterbatch masterbatch brightening also called light, the purpose is to increase the brightness of the light products, its main brightening agent is ethylene bis stearamide, general masterbatch dosage of 20%-30% products is 0.2%-0.3%, too much will affect the products of the printing effect. Enhanced masterbatch in production, sometimes the material easy to accumulate the feed inlet, the air entrainment caused mainly because of talcum powder, production should be heated and stirred, let the wax melted, moist talcum powder or white mineral oil. Hygroscopic defoaming masterbatch moisture defoaming masterbatch mainly can remove moisture and unknown low molecule containing a plastic in the volatile, so that the plastic products anhydrous flowers without air bubbles, so that in the guarantee quality of products at the same time can be subtracted from the drying process. Flame retardant masterbatch flame retardant masterbatch flame retardant modification is mainly used for occasions, foaming masterbatch foaming masterbatch used in PE, PP, EVA etc..
