Shanghai Daoqin Plastics Co., Ltd.

raw materials color currently main/primary has types methods, separation is masterbatch material color method, mixed combined color method, material surface cover/cap method and dry and method.

1, masterbatch material color method

this type of methods main/primary in injection molding 时, color solvent degree high has masterbatch material mixed combined to color material in, main/primary used for color product color.
                                  

2, mixed combined color method

main/primary material mixed combined in material in extrusion made formed has color material, most large advantages is color stability.
                                  

3, material surface cover/cap method

solvent has material coating material spray coating in material surface 进行覆 cover/cap, can light easy 举进行 color, meet/satisfy use demand. is and mixed combined method versus ratio, material dispersion property 差一.
                                  

4, dry and method

该 methods as difficult, but also molding rear very 麻烦, meanwhile material dispersion property good, generally by using/adopting.
                                  

raw materials color for material property effect/influence main/primary has 五 方面:

1, machine material property

raw materials color make machine strong/high degree has reduce meanwhile tough property can can decline, another in glass fiber reinforced grade raw materials in, add titanium powder white color can can formed machine material property decline increase large.

2, heat resistant property

resin natural color 不会发生变化, is color agent in separation understanding material has increase more can can property.

3, wear resistance

generally basic 不会改变.

4, weather resistance

weather resistance is color different has large degree 变化, this is due to is color make light can absorption degree 发生变化 缘故.

5, electrical features

color color products and color products electrical features 几乎没 has product, is black products 时, carbon effect/influence.
