Masterbatch for injection molding temperature many degrees
Release time：2016/9/23
Masterbatchfor injection molding temperature much better? We all know that one plastic molding injection method is the easiest way, and thus more and more of China's plastics factory. Injection molded plastic products out of good quality, production efficiency is high. Injection to the time required to use masterbatch coloring plastic materials, so the development of the plastic industry has also led to rapid progress masterbatch industry. At present our country masterbatch production technology has been very mature.
Masterbatch Factory basically rely on experience to determine the formulation of the method, Xiao Bian summarizes the color of precautions, as follows:
(1) the basic features of the first to understand the colored plastic colored plastic color itself. Because sometimes the same species, due to different manufacturers, brands or other reasons, often yellow phenomenon, when the color to be eliminated. In addition, the plastic often have additives, such as UV absorbers, antioxidants and the like will be leaving reaction products of pigment discoloration (in the sixth chapter) occur.
(2) the performance of all kinds of plastic pigment processing temperature is different, so you must pay attention to its heat resistance when choosing paint, otherwise the paint will decompose at high temperatures, discoloration.
(3) Conditions of Use Table 1-3 as a colorant commonly used plastic cases and requirements in formulating and molding.
(4) Color Design Steps
Looking reference coloring matter ① matching colored plastic from a known sample (sample), find the similar color as the reference sample.
② test formulation prepared carefully compare the similarities and differences between the reference and color sample color, shade, etc., and with reference to prepare a color test with color samples generally contained within.
③ color test formulations prepared according to color, until the registration date.
In order to ensure the accuracy of color matching, color matching should be sunny or sun, should continue to observe, in order to avoid eye fatigue due to the errors.
