Placke Plum is a professional manufacturer of masterbatch, how to control the cost of production of masterbatch, expanding profit margins, is the most important production work. Usually for small quantities of masterbatch, by way of one-component pre-dispersed production more economical, but if the amount of the claim must be considered with respect to savings in the production of pure pigment generated, the additional costs of the one-component.
1. masterbatch traditional production methods
Most masterbatch mainly made of powdered pigment. Single color desired by the pigment dispersing additives, such as wax and plastic raw material powder blending full and complete dispersion in twin-screw extruder, the uniformly distributed in the plastic material.
NOTE: In the laboratory twin-screw extruder dispersion effects and the actual situation of the production line is not necessarily the same, so in the production, must be at the beginning to check the color values, and make any necessary corrections.
2. One-component masterbatch production
Single color masterbatch production done in two steps, the first step is the production of one-component (the first production of high concentration masterbatch), then reproduction masterbatch. The maximum allowable concentration of pigment is dispersed in a plastic material called one-component method. Currently, organic pigments and the highest concentration of the highest concentrations of up to 40-50% up to 75% of an inorganic pigment can be dispersed by extrusion of plastics manner to obtain good dispersion.
Note: it refers to the dispersion of good quality plastic pigment particles are very delicate and can get the best possible color penetration, on the other hand, does not allow more than 5 micrometers pigment agglomeration, in order to avoid the formation of spots.
Sampling and laboratory color adjustment and masterbatch production-component is a single screw extruder completed. Since the pigment dispersion has been good, just different single component in a single screw extruder and melt mixed. For the same laboratory and the actual production of the dispersion quality, the actual transfer of the material obtained in laboratory color values in the actual production can be guaranteed.
3. The cost factors of production of extruded
Extrusion production costs (equipment costs, energy, labor, cleaning agents and waste, etc.) depends on the form and size of the machine and the size of the batch process used.
1. The twin screw extruder granulation
The organic pigment is dispersed in a twin-screw extruder to plastics to expenses not Fiji. Identical twin-screw extruder to diameter ratio of not less than 40, in order to ensure appropriate input, several members from the extrusion screw kneading function, this extruder generally produce a relatively small amount of organic pigment masterbatch .
High density inorganic pigment, more easily dispersed, so many high-yield production of a twin-screw extruder when. Thus, the dispersion of inorganic pigments unit cost is lower than the cost of organic pigments. The maximum pigment concentration and large machine mass production, the cost of one-component unit can disperse the pigment to a minimum.
2. The single-screw extruder granulation
Since the single screw extruder is not necessarily to be dispersed, you may only need to melt and mix, so the structure of a twin screw extruder simpler than many. Not only are more people willing to buy, but it also has the following advantages: easy to clean, produce low loss, easy to operate, clean, granular material, dust, mix quickly.
