| Color masterbatch used in moulding foaming products problem and its solution | |
| Release time：2016/9/24 | |
1, colour and lustre is shallow pigment content is low Causes: poor thermal stability of pigment. Solution: increase the color masterbatch pigment content, selected in line with the resistance to 180 ℃, 30 min of paint. 2, stomatal causes: pigment particles is large, raw materials have impurities, there is impurity in masterbatch, carrier are incompatible. Solution: to examine the raw material, improve the pigment dispersion, improve filtering masterbatch manufacturing and compatible in resin. 3, foam size instability causes: pigment crystal structure solution: increase the dosage of foaming agent, foaming temperature, to switch to paint new varieties. |
