In order to overcome the drawbacks dye coloring, improve the quality of plastic products, with the continuous development of the plastics industry, innovative types of plastic resins, additives types of plastics processing equipment and technology, a breakthrough, another way plastics coloring - - colored masterbatch has been widely adopted, colored masterbatch technology application and practice are continuously improved. The so-called masterbatch, pesticides colorants, which uses some kind of process and corresponding equipment, in the role of aid, the pigment (or dye) into the carrier, the price of pesticides colorant by heating, plasticizing, mixing, cutting action, and finally to the pigment powder and carrier resin molecular molecule fully combined, then made of the resin particles of similar size particles. Such a high concentration of colorants called masterbatch, its role and "saccharin" is similar to the use of pesticides colorant product, simply add the resin to be colored in a small proportion (1% to 4%) , you can achieve the purpose of the colored resin. Test methods (1) Determination of readily dispersible pigment test method: press pigment in plastic coloring Determination to take dilute PVC sheet in half, pesticide colorant companies, will roll surface temperature is controlled to 130 ℃, PVC sheet thickness 0.3 mm, plastic mixing for 7 to 8 minutes of the film. Tabletting temperature 165 ~ 170 ℃; the tablet dwell time of 1 minute speed cold. Assessment: The following two different shear mixing conditions improve color strength calculated dispersion. Where 5 is best, one worst. Credit pesticide colorant _ _ Weifang Fuyuan pesticide colorant provided by Environmental Protection Technology Co., Ltd. Weifang Fuyuan.
