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?
- Kaolin is hard or soft, chemical properties are similar, but the physical properties of different, soft adhesion, plasticity, suitable for ceramics.
- 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 is kaolin clay?
- Ordinary clays, also called Gan Zi soil or kaolin, are mainly composed of kaolin mineralsBentonite, also called acid clay, is mainly composed of montmorillonite minerals
- Q: Kaolin 200 mesh powder what does that mean? Is the eye powder the higher the better?
- This term is used to measure a number of quantitative powder size, it has a particle size and mesh size of the corresponding table, such as 200 mesh corresponding to the particle size of 0.075 mm, a special standard sample sieve to measure the particle size of raw materials, if the raw material specifications for 200 orders, to verify the Ontario with the 200 objective standard screen put a little powder in water washing powder to see whether all through, not all through, that nominal is not accurate.
- Q: What is the significance of the target in kaolin?
- At present, it is more popular to calculate the diameter of equivalent volume particles by particle size, in units of M or mm.
- Q: What is the difference between kaolin and rare earth, which is better to use as ceramic? What effect will it have?
- There are many kinds of rare earth including kaolin, such as vegetables, many kinds, including Chinese cabbage. Ceramics do ask the ceramic makers, I'm sorry I don't understand
- Q: Hard kaolin in the ceramic piece, which is used in which? What's the difference between washed kaolin and washed kaolin?
- Whiteness difference is big, generally after light burning, kaolin whiteness will increase, and wash water will not significantly increase whiteness.
- Q: What kind of soil can be used as a ceramic?
- As long as the soil can be made into pottery, the key is the temperature of the clay burning is appropriate, this is the art of ceramics need to master the most critical concept. What is mud? Can pinch, plastic, Potter, kiln porcelain. Which contains the earth's common minerals, said aluminum, called silicon, called lime, that is, potassium, sodium, and then mix a small amount of substances, such as magnesium, such as barium, its composition varies from region to region. So to the north or south and mud is different, can be called porcelain clay, and clay.
- Q: The difference between calcined clay and calcined kaolin
- Calcination can also make the crystal structure of kaolin changes (mainly caused by hydrogen bonding and crystal water removal layer), from the original ordered lamellar crystal structure of kaolin into disordered metakaolin, the exposed parts of the original crystal layer group, and due to remove water of crystallization, type and quantity of surface active the increase (the type changed from -OH to Si-O, Al-O and part of the remaining -OH), the reaction activity increased.Calcined kaolin can lead to particle size increased, while the decrease of surface area, adsorption decreased, but the decrease of surface energy, to improve the dispersibility of kaolin, and the amorphous structure became loose, but also can improve the dispersion of calcined kaolin after dehydroxylation. Usually by grinding or fine chemical surface modification as rubber plastic and other reinforcing filler of white smoke.Shvarzman replace some found that when the amorphous phase in the kaolin is more than 55%, according to the ASTM618 standard can be used as an active filler.
- 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
