Affect the color factor of CaCO3 Filler Masterbatch
In the plastic products industry, want to enhance the use of some of the properties of plastic commonly used method is to add CaCO3 Filler Masterbatch, it is this large number of needs, creating a large range of CaCO3 Filler Masterbatch now use. Not only in the plastics industry, more industries are beginning to use this product. But many companies found that CaCO3 Filler Masterbatch in the production process will often appear too long or too shallow color phenomenon, many companies do not know what part of the problem, for this situation, the following together to understand the next bar under it.
One reason: the color has not been carefully painted color, too little or too much paint caused;
Reason two: CaCO3 Filler Masterbatch in the process of using the measurement is not accurate, some small domestic enterprises, especially some of the processing of the workshop enterprises, this measurement is not accurate phenomenon often exist;
Reason three: CaCO3 Filler Masterbatch and resin match there is a big problem, which may be CaCO3 filler master carrier improper selection, it may be manufacturers to change the resin varieties;
Cause four: the machine temperature is not appropriate, especially high, CaCO3 Filler Masterbatch in the machine to stay too long, causing the toner burned.
Basically appear color difference of these four reasons, so the company in the CaCO3 Filler Masterbatch processing process also appears color problem, you can consider these four aspects to change some processing mode, basically can solve.
CaCO3 Filler Masterbatch is the main component of calcium carbonate, additives and carriers (the carrier refers to your CaCO3 Filler Masterbatch used in which plastic, such as used in HDPE, LDPE or some conventional PP, the carrier is PE or PP, such as used in PA, the carrier for the PA, used in polyester, the carrier is polyester). Which for the cost and performance considerations, CaCO3 Filler Masterbatch calcium carbonate content is generally between 60 to 80%. The higher the content of calcium carbonate, the lower the price, the lower the strength of the product, wear, compression and other physical properties of the more powerful impact.
For the common PE class plastic food bags, the ratio of 1: 1 will not have any effect (some low-grade food bags to add even more than 65%), unless your CaCO3 Filler Masterbatch is substandard products.
With the continuous progress of science and technology, we in the production want to better achieve the role of CaCO3 Filler Masterbatch, better promote the development of the industry, and promote the development of masterbatch progress, we must understand the CaCO3 Filler Masterbatch Characteristics and the situation in the filler.
Filling effect is good or bad with the dispersion, the smaller the smaller the size of the more difficult to disperse, the higher the price. Purity is another important technical indicators of inorganic filler, the less impurity content, the higher the purity the better. General use of heavy calcium carbonate, its content and whiteness as high as possible, so that can ensure that other indicators meet the requirements, the price is low, in order to help reduce the cost of masterbatch.
Polyolefin CaCO3 Filler Masterbatch used in the filler is mainly for heavy calcium carbonate, followed by talc, kaolin, calcium powder and other inorganic fillers. It is an important technical indicator for any inorganic filler, particle size and particle size distribution. Usually the smaller the particle size, the narrower the distribution, the better the filling effect.
CaCO3 Filler Masterbatch technology will also make use of technology in the future development of the application has made greater progress.
