The important position and function of polyester color masterbatch in plastic products industry in four aspects:
The main results are as follows:
(1) the coloring properties of polyester color masterbatch are outstanding.
Due to the direct contact with air in the process of storage and use of colorants, moisture absorption, oxidation, agglomeration and other phenomena are easy to occur. Direct use of colorants will appear color points on the surface of plastic products, the color phase is dark, and the color is easy to fade. The color masterbatch was machined in the production process, and the colorant was refined, and the colorant, resin carrier and various auxiliaries were fully mixed to isolate the colorant from air and moisture, thus enhancing the weather resistance of the colorant and improving the dispersion and coloring power of the colorant.
(2) Polyester color masterbatch is one of the key factors to determine the quality of downstream plastic products.
The proportion of polyester color masterbatch in plastic products is generally more than 2%. Although the cost in downstream enterprises is relatively low, it has an important impact on the beauty and quality of plastic products. Plastic products are generally large-scale, continuous production, if the use of color masterbatch color difference, dispersion, migration resistance and other technical indicators are not up to standard, often lead to the quality grade of the whole batch of products decline or even scrap, so downstream customers pay great attention to the quality grade and quality stability of color masterbatch. The development and deepening of color masterbatch technology has promoted the technological progress and industrial upgrading of plastic products industry.
(3) Polyester color masterbatch can promote cleaner production of downstream plastic products industry.
The use of color masterbatch in the production of plastic products can generally reduce the discharge of dust, sewage and other pollutants, protect the health of employees, but also reduce the waste of colorants, in line with the national industrial policy guidance and green environmental protection industry trend. Downstream plastic production enterprises are easy to cause dust flying when adding and mixing traditional powder coloring materials, which may cause health damage to production personnel, and need to clean the working environment often, resulting in a large number of pigment wastewater discharge. In addition, the dispersion of traditional powdery coloring materials in resin is worse than that of color masterbatch, which leads to more addition under the same coloring requirements. When the liquid coloring material is added and mixed, it is easy to splash and overflow, and it may flow out during cleaning, which can easily cause water resources pollution.
The color masterbatch distributes the colorant in the carrier resin, and the dust is less in the process of adding and mixing. The production environment of the downstream product enterprise using color masterbatch coloring is clean, the cleaning is simple, and the waste water discharge is reduced, which adapts to the trend and requirements of the cleaner production of downstream plastic products production enterprises. The color masterbatch has good dispersion and reduces the waste of colorant.
(IV) reduce the cost of integrated downstream use
Because the shape of polyester color masterbatch is similar to that of resin particle, it is more convenient and accurate in measurement, and will not adhere to the container when mixing, so it saves the time of cleaning container and machine and the raw materials used in cleaning machine. A small amount of functional color masterbatch is added to a large number of resins and processed once to become a product. Compared with the modified plastic technology, most of the materials go through one less processing process from resin to product, which not only saves the processing cost, but also is more beneficial to maintain the performance of the product. Functional color masterbatch shows a certain substitution trend for modified plastics.
