The color of plastic pallets is an indispensable part of the plastic industry, and its important meaning is to beautify products. As we all know, only when the beautiful appearance of a product arouses people's desire to buy, people will seriously understand its inner quality. The beauty of any product mainly depends on its appearance and color, and the realization of harmonious colors needs to rely on coloring technology to be implemented. The colorful colors give people a beautiful artistic enjoyment. The second important purpose of coloring plastic pallets is marking. The marking effect is achieved through coloring, which has practical value. Local telephone communication cables use Munsell color-coded chromatographic identification, which brings great convenience to wiring and maintenance. Expressway uses eye-catching reflective signs, traffic police uniforms use eye-catching fluorescent yellow during the day, and sanitation workers use eye-catching orange as safety signs.
Coloring plastic pallets can also endow plastic pallets with multiple functions to meet various needs in applications.
(1) Improve the light resistance and weather resistance of plastic trays. Carbon black is used to improve the light resistance and weather resistance of polyethylene plastics, which can play a very prominent effect. It is reported in the literature that in 100 parts of low-density polyethylene, 1.5 parts of carbon black are added. After one and a half years of outdoor exposure, the elongation at break of the film is still as high as 190%. The pure low-density polyethylene film used in the comparison test is in the above If the test is carried out under the same conditions, the elongation is basically lost.
(2) Give some special functions and add conductive carbon black to give the conductivity of the plastic, which has been widely used in the inner and outer screens of power cables. Clothing made of composite fibers with conductive carbon black has an antistatic effect, and is now widely used in labor protection clothing for computer and electronic component manufacturers.
