Formulation of special ingredients for Christmas tree
Formulation of base material formula
According to the test results, established by experience formula, through continuous modification formula, similar to the mechanical properties and processing properties and material until the Christmas tree so far. It should be pointed out: for white, light colored and colorful products, not to use the deep color additives (such as P-CI), the filler should not use the whiteness poor (with dark coupling agent treated filler). In order to save space, this article will elaborate on the process of formulating the base material formula in detail.
The formulation of the color formula of the Christmas tree
We determine the sample material is composed of Christmas green, yellow and black three colors, according to the existing special pigment yellow, yellow, yellow Vc802, YONGGU fluorescent green, phthalocyanine green, light resistance, heat resistance, carbon black
The lower limit of tolerance, migration and chemical resistance, electrical insulation, toxicity, coloring power, covering rate, dispersity and coloring cost will be re used for reference. Reasonable selection of pigment, phthalocyanine green, yellow, select three kinds of special carbon black pigment. How to determine the concentration of the pigment is not easy, you can take the following measures: first to determine the concentration of the pigment according to the reference and experience. Second the reference and comparative coloring, find similar color. Then determine the concentration of the pigment. The first two measures we cannot use, had to use third measures - coloring method, first phthalocyanine green, yellow, black. According to different proportion mixed together, with plasticizer o-benzene two formic acid two Xin vinegar into paste is easy to flow, easy to disperse, the paste will be tuned respectively. Even Xu Zaiji sheets of material, find the sample are similar to that of pigment concentration was determined for roughly 10 phthalocyanine green abalone, especially yellow 45g, carbon black 50g. using the method of color pigment Xu, can not transfer too thin or too thick, the former adverse observation, the latter dispersion is not good, Xu layer is not uniform. The thickness of the Hsu layer is suitable for covering the base material. The use of the Hsu method to determine the concentration of the pigment is relatively large, and the method is not easy to grasp. Set color formula, we should pay attention to some color techniques: two color is its complementary blending, color or dark color dull. Not only to pay attention to the color of the tie, but also pay attention to color with the color. We should try to use the similar nature of the pigment, so as to avoid the heat degree of different pigment, color effect results. Color matching should be used as little as possible when color matching, otherwise it will bring many unnecessary troubles.
