1.What is the Color Masterbatch?
Color masterbatch and Nama Rupa is a ultra constant pigment or dye uniform carrier attached in the resin and the pigment concentrates.
2.The use of Color Masterbatch and what are the benefits?
A. It is beneficial to keep the chemical stability and the stability of the pigment;
B. So that the pigment in the plastic has a better dispersion;
C. To protect the health of the operator;
D. The environment is clean, the working procedure is simple, the color change is easy.
3.What is the basic component of Color Masterbatch?
A. Pigments or dyes;
B. Resin carrier;
C. Dispersant;
D. Additive.
4.What Color Masterbatch variety and grade?
Color classification methods commonly used are the following:
According to the vector classification: PE PP ABS Color Masterbatch, masterbatch, masterbatch, masterbatch, masterbatch and other EVA PVC.
Classified according to purpose: such as blowing masterbatch, masterbatch, masterbatch injection pipe etc..
5.With the masterbatch coloring products will fade?
Use color masterbatch coloring products may still faded, only for different grades of products using different properties of the pigment, and a different degree of fading, some obvious, while others are very hard to detect. But if the customer request, our can specialized technical treatment in processing Color Masterbatch, so as to prolong the product color persistence. Of course, I Division in the color will be based on the grade of the product or use, consider the durability of its color.
6.Method of using Color Masterbatch?
The use of color masterbatch is very simple, as long as according to a certain proportion and plastic resin filling mixed and meet the requirements of different kinds of plastic processing technology, extrusion molding can be.
A. Need to pay attention to is color conversion must be hopper clean, plastic color or add screw cleaning agent machine material residual material in the drum washing clean;
B. Pay attention to the temperature and mix proportion is correct, in case the color change.
7.What is the proportion of Color Masterbatch?
Can be added with the customer needs, reference to the company's added scale range to determine the test. General use ratio is:
1% prone to the phenomenon of uneven pigment dispersion, generally do not recommend the use of this proportion of customers;
2-3% used for coloring requirements of ordinary plastic products, PE, PP are widely used in the proportion of color masterbatch;
4% and above for coloring high blown film, injection molding, spinning process;
8.Masterbatch occurred during storage of pigment migration will affect the quality of the product?
Some color pigment (or dye) content are very high, in this case, the migration phenomenon is normal. Especially adding dye masterbatch, the migration occurs serious phenomenon. But this does not affect the product quality, because masterbatch add into the raw materials into the production of products, pigment in the product in normal concentrations of coloring.
9.Color Masterbatch retention period how long?
Color can be preserved for a long time. The pigment masterbatch was dispersed parcels in the carrier resin, in a closed state, physicochemical properties will not change, but need to pay attention to moisture.
10.The common defects in the process of using the masterbatch
A.In the sunlight, the products have stripe like pigment with:
May cause: a. Injection did not control the temperature of the device into the mixing cavity, masterbatch and resin can not be fully mixed; b. Injection molding machine does not add a certain back pressure, screw mixing effect is not good; c. Color dispersion is good or not good plasticizing resin. To do the following debugging: a. Will mix cavity by the drop of the material mouth part of the temperature slightly increase the; b. To the injection molding machine to put some back pressure. If the above test is still not mend may is color masterbatch, resin dispersion or matching problem, should be resolved and color masterbatch manufacturer.
B.Masterbatch, resin and the same formula, injection molding machine outjection different products why color shades?
This is often caused by the reasons for the injection molding machine. Different injection molding machine due to the manufacture, use or maintenance of different, resulting in the difference between the mechanical state, especially heating of the original and the barrel of close fitting degree difference, the color masterbatch in barrel decentralized state is not the same, the phenomenon will appear.
C.Another sign of the resin, the same color and formula, color has changed, this is why?
The main reason:a. Raw materials using a color not consistent; b. Presses is not clean temperature; c. Used color masterbatch or toner low degree, changes the achromatic; d. Process when the temperature is too high; e. Masterbatch or toner color; f. Mixed feeding machine is not clean or mixing time do not control.
D.Why some products gloss is not good?
There may be more of the following: a. Extrusion temperature is too low or too high; b. Product heating time is too long; c. Bottom material quality unstable; d. Masterbatch dispersion is not good.
Because there are many factors in the production process, and plastic coloring is a lecture and learn as much knowledge, our knowledge is limited, are impossible in this one Xiangxi Zen said. So we strongly recommend users to debug, in order to the best use of the results. In the process of debugging, such as the problem can not be solved with our factory, we will try our best to help customers solve every problem we can solve.
