How to identify plastic bottle top grade product and defective skills

1, pigment and dye additives in recent invention of anti-counterfeiting technology, have adopted a 'color' the paint. These additives containing multiple polymerization light reflective coating, coating around a piece of reflective aluminum chips, make plastic color change with different viewing Angle. The change of color, such as red green, but because from different YanLiaoCeng caused by the influence of the Angle of the reflection of light waves. Color pigments make plastic consumer products have a significant effect of aesthetics, and because of these effects is not easy to be cloned, so also has the function of anti-counterfeiting. A method for the identification of whether is the plastic parts factory, is to put the bottles and mixed pigments or dyes, using spectrometer to expose part is analyzed, and the ultraviolet those pigments or dyes will show unique design. Although counterfeiters on their plastic products using very similar color, also can't get the same spectrum as genuine. Color pigments can blend into many kinds of resin, such as PC, pp, hdpe, pet, abs, thermoplastic pu, such as cellulose acetate and pa12 varieties. Color pigments in the resin weight than usual at 0. 2% ~ 0. 4%, can be used, such as injection molding, blow molding, hot extrusion molding, calendering, extrusion film and internal decoration such as standard technology for processing. 2, particle identification had developed micro identification purposes, is in order to in the case of * * * event can help track the source of explosives, but is now widely used in tracking and identify the authenticity of a plastic products. That contain specific resolution is the most typical particle identification function of color design or contain special chemical composition of polymer particles, the particles before type molds can be mixed with thermoplastics in advance. With identification of particles often mixed with plastic powder in advance, make its can be used for molding or enrichment, dilute when processing can be molded. In injection molding, extrusion molding plastic molding or the striped mini label on the plastic parts, through a microscope or design resolution meter scan can clearly recognize it. Some manufacturers make logo into fluorescent type or with magnetism, in this way, using ultraviolet light meter or magnetic scanner can easily identify the authenticity. Small particle diameter of less than 50 microns ( Equivalent to the size of the bacteria) About 600 microns (, big Equivalent to the size of a grain of) That is not the same. These particles inert substance, usually don't react, and can bear the high temperature when the molding processing without damage. By varying each particle on the number, type and the collocation of color or changing the chemical property of the particle surface, can produce millions of various distinctive mix coding. Due to the resin containing particles with coding, using a special instrument read code would then be able to identify the manufacturer and product information.
