White masterbatch widely used for the production of injection products, blown film bags, as well as the production of cast film and so on. Because the white masterbatch of titanium dioxide content is high, so the plastic products produced by high brightness, in terms of temperature performance is also very good, the physical properties of the raw material itself has no effect.
White masterbatch with bright color, bright and dazzling, high color strength, good dispersion, high concentration, good whiteness, hiding power, reasonable price, White Masterbatch resistance to migration and good heat resistance and so on. To ensure product quality and yield, reduce energy consumption and improve production efficiency. Is a new generation of economic white mother of the characteristics.
So in many colors of masterbatch, the white masterbatch has become the production of plastic products, the conventional color, the amount is very large. Thus, in the development process of the production of white masterbatch technology also requires more and more. In particular, White Masterbatch the higher the content of titanium dioxide, may cause the product to be scattered uneven or mixed color and the like.
White masterbatch part of the titanium dioxide whitening agent if the use of these two kinds of stuff may make your product pattern and so on
White masterbatch selection method: carrier reasonable concentration
White masterbatch and toner price contrast masterbatch will be slightly higher but almost negligible
Precautions when using white masterbatch
1, in order to reduce the color difference after color matching, the white masterbatch to be diluted to control the mixing ratio, the filament of not less than 3% to 10%, White Masterbatch staple fiber of not less than 1% to 3%, monochrome expanded continuous filament With three-color equipment spinning, white masterbatch must be mixed in the input after the extrusion machine, while increasing the melt itself, the mixing capacity, White Masterbatch can also be added in the extrusion section of the mixing device.
2, white masterbatch mixed with color in the color formula to determine the white masterbatch before spinning evenly dispersed in the polypropylene slice, is to ensure product quality key, the specific method of mixing there are two categories. One is the heavy method and volume method, in the extruder or the back of the white masterbatch melting, with a small extruder into the polypropylene melt, uniformity is very good.
3, select the white masterbatch, according to the choice of choice, polypropylene masterbatch fine denier, coarse denier of the points, coarse denier white masterbatch color can not be used for fine denier color, White Masterbatch color should be considered spinning Fiber single filament denier, White Masterbatch select the same level of white masterbatch.
4, the choice of white masterbatch is best the same manufacturer's products, in order to reduce the cost should use high-density white masterbatch. White masterbatch pigments are high, medium and low-grade points, color should be based on fiber quality requirements, the appropriate choice of different levels of white masterbatch. In order to avoid the pigment light and thermal stability caused by different quality of finished fiber variation, color should also choose to meet the fiber quality requirements, with the same light, White Masterbatch heat stability level of white masterbatch color, coarse fiber than the concentration of fine fibers Low, the application ratio of white masterbatch is proportional to the square root of fiber denier.
