一般情况下,塑胶着色剂有两种,一种是使用色粉,另一种就是使用色母,色粉和色母就是现在通用的塑胶专用颜料。

In general, there are two kinds of plastic coloring agent, one is the use of color powder, the other is the use of the color mother, the color powder and the color mother are now the universal plastic special pigment.

色粉是指有颜色的粉状物,色母粒简单理解就是指带有颜色的颗粒,这里的颗粒是一种载体,就是让颜色附着在载体上,然后再配合塑料达到调色的目的!

爱乐透彩票Color powder is the color of powder, color masterbatch is simply to understand the color of the particles, the particles here is a carrier, is to make the color attached to the carrier, and then to match the plastic to achieve the purpose of color.

与色粉着色相比,色母粒着色有以下明显的优点:

爱乐透彩票Compared with toner coloring, color masterbatch coloring has the following obvious advantages:

1)改善了由于色粉飞扬带来的环境污染问题,使用过程中换色容易,不必对挤出机料斗进行特别的清洗,倍感方便。

1) to improve the environmental pollution caused by the flying color of the powder, it is easy to replace the color in the process of use, and it is not necessary to carry out the special cleaning of the hopper of the extruder.

2)针对性强,配色正确。由于色母制造工厂在制造过程中已针对适用树脂的性能,合理地选择了颜料(染料)、助剂、加工设备、加工工艺,对生产过程中不同批号的色粉可能带来的色差,及时进行修正、补色,出厂时再进行检验,因此,可以保证相同牌号的色母,前后两批颜色保持相对的稳定。

2) the pertinence is strong and the color matching is correct. In the manufacturing process of the chromophore manufacturing plant, the pigment (dye), auxiliaries, processing equipment and processing technology are reasonably selected for the performance of the suitable resin. The chromatic aberration that may be brought about by different batch of color powder in the production process is corrected and colored in time, so the phase can be checked again. Therefore, the phase can be guaranteed. The color of the same brand is kept relatively stable in the two batches.

爱乐透彩票3)与成批树脂干法染色造粒后再去制塑件相比,使用色母可以减少塑料制品经二次加工后所造成的树脂性能老化,有利于塑料制品使用寿命的提高。

3) compared with the batch resin dry dyeing and granulation, the use of the color parent can reduce the aging of the resin property caused by the two processing of the plastic products, which is beneficial to the improvement of the life of the plastic products。

使用色母比较大的优点是:在加工过程中,颜料在助剂的作用下,色母粒经过充分混炼与载体树脂完全结合。在使用时,按一定的比例置于待加工的树脂中,色母很快地进入角色,与该树脂认"亲家"。亲和力——相容性明显优于色粉着色,因此,对于生产薄膜与纺丝制品的厂家来说,更能体会到。

爱乐透彩票The biggest advantage of using color masterbatch is that during the processing, pigments are fully mixed with carrier resin under the action of additives. When used, the resin is placed in a certain proportion in the resin to be processed, and the color master quickly enters the role and identifies the family with the resin. Affinity - compatibility is obviously better than coloring, so it is better for manufacturers of film and spinning products.

当然,色母粒着色也有其局限性,由于添加量少,塑料制品的加工时间短,受挤出机螺杆长径比的限制,色母分散性往往不如色粉。多了一次制造过程,染色成本也必定高于色粉着色。色母中的载体与需着色树脂的性能有差异时,塑料制品表面常常会出现未分散点、色斑、花纹,所以,色母的使用因其相容性及分散性而受到限制。

Of course, color masterbatch coloring also has its limitations. Due to the small amount of addition, the processing time of plastic products is short and the length to diameter ratio of the extruder screw is limited, and the dispersivity of the color parent is often inferior to that of the color powder.  More than one manufacturing process, dyeing costs will also be higher than toner coloring. When the performance of the carrier in the color parent is different from that of the required coloring resin, the surface of the plastic products often appears undispersed, color spots and patterns, so the use of the color parent is limited by its compatibility and dispersion.
