Choi Jin Second lesson:
How to Keep Your masterbatch to reduce production costs?

Generally 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.

To add the required materials, masterbatch is added to the processing of plastic raw materials in the proportion of generally 1-5%, the concentration of pigment in the masterbatch most common is 20-30%, and only in exceptional cases, the largest masterbatch concentration was comparable to the desired concentration of the pigment dispersion.
   
Keywords: traditional masterbatch production

Most masterbatch mainly made of powdered pigment. Single color desired by dispersing pigments and other additives such as wax blended with powdered plastic raw materials adequate and complete dispersion in twin-screw extruder, the uniformly distributed in the plastic material. In the laboratory twin-screw extruder dispersion effect is not necessarily consistent with the actual situation of the production line, so in the production, must be at the beginning to check the color values, and make any necessary corrections.

            
Keywords: one-component production using masterbatch

Single color masterbatch production done in two steps, the first step is the production of one-component, 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.

Good dispersion quality refers to the 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. A way to check the quality of the dispersion of very simple method is to paint the dye solution to the foil, with the naked eye and a microscope to find the stain.
      Plastic pigment can be dispersed depending on the number of pigment, dispersing aid and basic materials may be. First, pigment and plastic powder and a suitable dispersant fully mixed, and then dispersed in a twin-screw extruder.
   

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.
 
Keywords: economic factors to be considered

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.
 
In a twin-screw extruder organic pigment dispersed in plastic to expenses not Fiji. Identical twin-screw extruder to diameter ratio of not less than 40, in order to ensure appropriate input, several extrusion screw member from a blend of features, this material is generally a relatively small production yields organic pigments. 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-scale machine production volume, cost-component units dispersed pigment to a minimum.

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.

25-1000 kg when processing small quantities of masterbatch, the general use of smaller machines. In view of the above-described single screw extruder having a bit, with a small extruder (e.g. a screw diameter of 45 mm) up to the processing of 500 kg batch advantages the most obvious.

With respect to the powdered pigments, formed by the additional cost of producing one-component compensated. Because you can very quickly change color, masterbatch manufacturer has received a desired flexibility (rapid response units).
    
If the masterbatch production of more than 3 tons, with single and twin screw extruder production costs considerably, at this time, the most economical way must be set according to the recipe. If the inorganic pigment (eg: TiO2) and organic pigments to be dispersed with mixing in a twin screw extruder, worth an organic pigment portion in the form of one-component added, so long as its distribution into it). Since the organic pigment does not require re-dispersed inorganic pigment can be dispersed in a high output speed.
