How to detect the color master

We pass a series of tests when the production color master is used, and can be shipped as a qualified product. Commonly visible with color, dispersibility, ash, melt index, etc., the specific detection method is as follows:

I. Color and dispersibility detection of color master materials:

1. Color detection: Add the same raw material as the vector to the proportion (1% or 2%), at a temperature of 170 ° C -190 ° C (depending on the raw material), by injection molding 5.5 ㎜ thick flakes, compared to the sample The light-color can be tested in the contrast, and the dark color can compare and debug according to the experience of good light.

2, the dispersion is pressed into a film in the same ratio and temperature, and the number of pigment particles is observed.

Plastic masterbatch belongs to the intermediate link of the plastic product industry, is the downstream of pigments and petrochemical products, upstream of plastic products, and plays an important role in the plastics industry.

The important status and role of plastic masterbatch in the plastic product industry are shown in four aspects:

(1) The color strength advantage of the plastic masterbatch is outstanding

Since the colorant directly contacts the air during storage and use, it is prone to moisture moisture, oxidation, and group, and the color point is used in the surface of the plastic article, the color is dark, and the color is easily fade. The color masterbatch is mechanically processed during the production process, and the colorant, the resin carrier, and various auxiliary agents are fully mixed, so that the colorant is isolated from the air, thereby enhancing the colorant. Weight resistance, improved the dispersibility and coloring force of the colorant.

(2) Plastic masterbatch is a single factor in determining the quality of the lower reaches of plastic products

The addition ratio of the color masterbatch in the plastic article is 2%, although the cost of the downstream enterprise production link is relatively low, but the beauty and quality of plastic products have an important impact. Plastic products are single-scale, continuous production, if the technical indicators such as color mother particles, dispersibility, mobility and other technical indicators often lead to high decline in the quality of the whole batch of products, so the downstream customers are very concerned. High and quality stability of quality and quality stability. The development and deepening of color masterbatch technology has promoted the technical advancement and industrial rise in the plastic product industry.

(3) Plastic masterbatch can promote the clean production of downstream plastic products industry

In the plastic product production, the use of color masterbatch can be reduced from the general reduction of pollutants such as dust, sewage, protect employee health, and reduce the waste of collectors, which meets industry policy orientation and green environmental protection. Downstream plastic manufacturers are easily caused by flushing and mixing traditional powdered materials, which may cause health damage to producers, and need to be cleaned with work environments, resulting in a lot of discharge of pigment wastewater. Further, the dispersibility of the conventional powder colorant in the resin is different, resulting in the addition amount of more than the equivalent coloring requirements. It is easy to spill in liquid coloring materials, and it is possible to flow when cleaning, which is easy to cause water pollution.

The color masterbatch disperse the colorant in the carrier resin, the dust is less during the addition and mixing process; the production environment is clean and cleansing the downstream product enterprises in color masterbatch, the cleaning is simple, and the wastewater discharge is reduced. Trend and requirements. The toner is dispersible, reducing colorant waste.

(4) Reduce downstream integrated use costs

Since the color master particles are similar to the shape of the resin particles, it is more convenient and accurate, and when mixed, it is not adhered to the container, thereby saving the time of cleaning the container and the machine and the raw materials used in the cleaning machine. Adding a small amount of functional color masterbatch to a large number of resins to become a product. Most materials have experienced single processing processes from resins from resins to the article, most of the materials have experienced a single processing process, which not only eliminates processing costs, but also more beneficial to maintain product performance. Functional masterbatch exhibits a single alternative trend in modified plastics.
