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: There is a kind of kaolin powder used for making cables. It does not sink in water. It does not damp with a stick. It wants to know what is added in it
- The question about the reform of kaolin can not be explained in one or two words. Remember my name and contact me by telephone.
- Q: What are the surface modification technologies of calcined kaolin and the matters needing attention?
- During the surface modification of calcined kaolin, it is necessary to react at a certain temperature. So, first of all to the calcined kaolin dynamic heating to a certain temperature (100 DEG C), in the high dynamic condition, adding after hydrolysis of silane coupling agent or compound modifier, adding to the best atomization. During the reaction between the coupling agent and kaolin, the temperature should be kept within 120 degrees, and at high speed, the time should be about 3-5 minutes.In addition, surface modification of kaolin and the reaction process, often produce false knot particles, the impact on the quality of the products is given, so the need for effective classification, only in this way can we fully guarantee the quality of products.
- Q: Where are the main differences between kaolin and kaolinite?
- There are three types of kaolinite subgroup, including kaolinite, crust stone and Pearl stone. Their theoretical formula is Al[Si4O10] (OH) 8, without water between layers.
- Q: How do porcelain mud distinguish good or bad?
- The difference between the mines leads to uneven composition and leads to inconsistent quality. The loss of many mud and glazes in China is very important for this reason.
- Q: The difference between clay and porcelain
- Clay fired ware called pottery, porcelain clay porcelain ware is fired, this is the difference between the two.
- Q: How can clay sculptures not be cracked and preserved for a long time?
- Kaolin, sculpture and other clay materials, after drying with water, there is a big contraction, which led to cracks. Do not want to crack
- Q: How to distinguish the good or bad of kaolin?
- Kaolin is based ceramic preform molding, has good plasticity and binding, can effectively reduce the deformation and cracking of the embryo, with high fire resistance and burning degree, can enhance the mechanical strength, can improve the thermal stability and chemical stability and sintering properties, good suspension property and adsorption in ceramics in the process of color glaze. The product also has three oxidation, two aluminum content, high iron, manganese, titanium and other harmful impurities, low ore, ore and concentrate quality stability, etc., is a high quality kaolin.
- Q: What's the difference between Ye Lashi and kaolin?
- The main components of both are Si and Al compounds. The main difference is that the content of the main components is different. The content of Si and Al of kaolin is close to that of kaolin, and the amount of burning of kaolin is relatively large;
- Q: Does kaolin ore hazard do harm to human body?
- Is the application of kaolin surface, different texture, can directly affect their voters to change the pottery and porcelain kiln relics, it can produce high-quality kaolin excellent, tend to be more in the surrounding building.
- 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.
