Calcium carbonate, calcium carbonate masterbatch granulator and plastic properties of the basic requirements for calcium carbonate calcium carbonate features widely used in plastics, to give the plastics industry attention is not accidental, compared to other non-metallic mineral powder material, Calcium carbonate has obvious advantages. 1) cheap either GCC or light calcium in various non-ore materials is the lowest price, meaning any kind of non-ore materials merely trying to replace the use of calcium carbonate as a plastic filler, rather than highlight it seed powder characteristics of the material itself, it makes no sense. 2) good color, easy to color and can do light-colored plastics. The downside is that colored plastic color bright enough, in most cases still acceptable. 3) low hardness Mohs hardness of 3, far below the manufacturing and processing machinery and mold the hardness of steel (such as nitriding steel, high speed steel) by filling plastic parts in contact with the device (screw, barrel, etc. Therefore, ) and mold wear lighter. 4) good thermal stability and chemical stability at the temperature of the thermal decomposition of calcium carbonate is above 800 ℃, will not occur in all the plastic processing temperature (300 ℃ or less) thermal decomposition of calcium carbonate is a strong base weak acid salt, in addition to In case of an acidic medium, the good chemical stability. 5) easy to dry, no crystal water, moisture absorption easily removed by heating. 6) non-toxic, non-irritating, tasteless, especially in our country calcite, marble, rich limestone resources, you can choose a large room, excellent quality and the vast majority of resources, especially heavy metal content is very low, up to the national sanitary requirements. Effect of calcium carbonate to fill the plastic properties of 1) the impact of TSP density and light density of calcium in the real difference is not obvious, the former is 2.6 ~ 2.9g / cm3, which is 2.4 ~ 2.6 g / cm3, the main difference Lord is a significant difference to the bulk density, the volume of industrial settlement to distinguish between GCC and light calcium, which in absolute ethanol 2.5mL / g or more as light calcium, GCC at 1.2 ~ 1.9mL / g. http://mayu1991619.jdzj.com/ http://mayu1991619.b2b.youboy.com/ http://m1991619.cn.china.cn/ http://mayu1991619.955101.com/ http: // mayu1991619. cn.gongchang.com http://www.datoumao.com/gongsi/mayu1991619/ http://www.kejiqi.org/corp/mayu1991619/ http://mayu1991619.8j8.cc/ http://mayu1991619.cn .b2b168.com // http://www.sooshong.com http://www.cntrades.com/b2b/mayu19911619/
