What factors will affect the calcium carbonate filling masterbatch
的品质却是参差不齐，作为同一厂家出来的碳酸钙母料都会出现不一样的品质。 Calcium carbonate filling masterbatch is the most common type of filling masterbatch on the market, but the quality of calcium carbonate filling masterbatch on the market is uneven. As the calcium carbonate masterbatch from the same manufacturer will have different qualities.
From the perspective of chemical properties, calcium carbonate is an inorganic material and rich in resources. From a microscopic perspective, it is hexagonal and tetragonal, mostly crystalline particles. Many calcium carbonates have relatively high whiteness and good fluidity. Obtaining calcium carbonate is also extremely simple, so it is widely used in filled modified plastics. The following editors will introduce to you which factors have an influence on the calcium carbonate filled masterbatch?
I. Calcium Carbonate Content This is the most important factor that affects the professional filling masterbatch, but there are fixed technical indicators for the calcium carbonate content. Generally speaking, the filling masterbatch has relatively high requirements for its content. Its processing performance stability and carbonic acid Calcium calcium content is directly proportional, so in order to avoid the frustration of filler masterbatch in use, and to prevent the content of non-metallic impurities from being too high, we must grasp the content of calcium carbonate.
Second, the whiteness of calcium carbonate In many cases, it is found that the whiteness and coloration of filled master batches are not good. This is mainly because the whiteness of calcium carbonate directly affects it. Because of the whiteness of calcium carbonate in the filled masterbatch industry, The regulations are extremely strict, and for decades, filling masterbatch manufacturers have extremely delicate whiteness requirements.
Third, the moisture of calcium carbonate First, we analyze from the raw materials of calcium carbonate. The raw materials of high-quality modified masterbatch are mostly calcite and natural marble, so there is no moisture; but after a series of processing procedures, It is a powdery powder. In addition, it is often absorbed by moisture during storage and transportation, and a small amount of volatiles are generated in it. Once the volatiles are too high, it will have a large impact on the filling masterbatch.
