There is no uniform industry standard for Flexible Hose, so manufacturers and customers to meet the product color, PVC fiber in the transparent outer tube in red, white and blue porcelain garden in the black and orange pipes, gas pipes, color type hose vary widely, how to solve the problem of product color?
1. under different light sources, the exterior color of the Flexible Hose is different. To understand the color under the light source, there is no special requirement. It is natural light, fluorescent lamp, especially the color plate containing fluorescent pigment, which can be displayed differently under different light sources such as natural light, fluorescent lamp, ultraviolet light and so on.
2. no matter what color, first ask what is plastic, from raw material categories, can put the toner into soft or hard rubber to narrow the scope, according to the forming characteristics and conditions in the selection of plastic temperature or high temperature, toner, toner, so should be chosen according to the plastic forming process of medium temperature or high temperature, toner, toner.
3. be aware that the Flexible Hose sample is transparent, semi-transparent or opaque. If it is transparent, it is necessary to choose transparent organic pigments or dyes. If semi-transparent or opaque samples are transparent, it is necessary to estimate the amount of titanium dioxide based on experience. Color matching is the first step to determine the amount of titanium dioxide. This is the key to the relationship between color matching technology and color matching speed. Otherwise, the amount of titanium dioxide will change and the color will change greatly. Other pigments will also change. With the addition of titanium white powder, the transparency of the plastics will be reduced. With the increase of the amount of titanium dioxide, the color phase becomes shallow. Deep color products usually do not use titanium dioxide, but we also need to see the sample.
4. to understand the weather resistance, chemical stability requirements, plus no other additives, to promote non-toxic, tasteless high-end Flexible Hose products. One principle: choose the suitable color powder according to the requirement, if there are fillers, additives and so on, it should be added in proportion when the color is adjusted. In order to meet the requirements of environmental protection, pay attention to control the safety of every kind of color powder.
