1. Benefits and Application
The GB-CK series of Kaolin based pigments are produced through delamination,
calcination and classification. The well-controlled processes ensure the GB series have no coarse particles and maintains an absolute minimum of 325 mesh residue, so the end user can achieve a high Hegman grind. The GB series pigments also have high brightness, strong hiding powder and superior dispersibility, and it is widely applied in latex paint, powder coating and electrophoresis coating.
Its main benefits are:
It’s the best extender of titanium dioxide with excellent opacity that can
improve efficiency and cut costs by partly replacing titanium dioxide;
It can easily disperse in water based systems;
It offers superfine particle and with excellent anti-settling property; It is inert to most acids and
alkaline at ambient temperature and offers good anticorrosive capabilities.

4.Application
- Q: Can pure kaolin or montmorillonite burn pottery? If not, what do you need to add?
- More than two of the hard nature of the poor, so the use of ceramics in relatively small, mainly chemical raw materials. However, because of the scarcity of soft soil and higher prices, many manufacturers have been studying the hard kaolin and other viscous ores to achieve the above results. That is, it can reduce the cost and produce better ceramics.
- Q: What's the difference between nano kaolin, washed kaolin and calcined kaolin? Where is the difference?
- The purity of calcined kaolin is enough kaolin, after high temperature firing out after grinding of kaolin, in order to improve the whiteness and purification, the firing temperature according to customer's product requirements vary from 900 degrees to 1300 degrees are
- Q: What are the requirements for kaolin as refractory material, such as how much aluminum is needed?
- Kaolin aluminum content does not have to be too high, more than 38% on the line, viscosity is to consider, the best sticky point, so as not to add extra bentonite. Fire resistance of more than 1400 degrees enough
- Q: What's the requirement of high-grade kaolin?
- Brightness is a process characteristic similar to that of self, which is equivalent to the degree of self - illumination under the 4570A wavelength.The color of kaolin is mainly related to its metal oxides or organic matter. Containing Fe2O2 was rose red, brown and yellow; Fe2+ is light blue, light green, light brown with MnO2; organic matter tends to yellow, gray, green, black and other colors. The presence of these impurities, reduced the natural whiteness of kaolin, in which iron and titanium minerals will also affect the degree of calcination, porcelain stains or scars appear.
- Q: What are the characteristics of kaolin in ceramic materials?
- China glaze more. The porcelain is roasted at high temperature, the carcass is firm and compact, and the section does not absorb water, knocking it out with a crisp metallic sound. To make porcelain, select the soil, especially the kaolin found by the people of Jingdezhen. Kaolin plays a key role in improving the smoothness, compactness, whiteness and hardness of porcelain.
- Q: Kaolin calcining temperature
- Clay can be divided into hard clay (hard clay) and soft clay (soft clay). The hard clay particles with smaller particle size, below 2 m accounted for 87-92%, its good reinforcing effect, soft clay, coarse particle size below 2 m accounted for 50%, more than 5 m about 25-30%, the reinforcing.Hard clay and not only for the poor classification on the mineralogy, the rubber with have different differences, especially the influence on the synthesis of the more obvious natural rubber.
- Q: What are the colors of kaolin ore?
- Contains the quality is pale yellow, gray, green, black and other colors. The presence of these impurities, reduced the natural whiteness of kaolin, in which iron and titanium minerals will also affect the whiteness of the calcined, porcelain stains or scars appear.
- Q: This is a stone dug with kaolin. Does anyone know what it is?
- The stones dug together with kaolin are quartzite,
- Q: What is the significance of the target in kaolin?
- The granularity is particles can be obtained by screen mesh size, with 1 inches (25.4mm) the number of mesh width of the screen mesh representation, so called "mesh". At present, there is no uniform powder particle size standard at home and abroad, and each enterprise has its own definition and representation of particle size index. In different countries and different industries, the screen specifications have different standards, so the meaning of "target" is difficult to unify.
- Q: Heroes, help me see if this is quartz sand or kaolin? Is it valuable?
- It's quartz sand. The aluminum content of kaolin is very high, at least above forty percent
