Product Description:

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.

Q:What is the good or bad of kaolin to distinguish? What is its criterion?What percentage does it contain and what element does it contain?
Kaolin is a kind of soft clay mineral and two non clay mineral, which are mainly composed of kaolinite and sub group minerals. Kaolinite minerals are mainly composed of small tabular or tubular kaolinite minerals of less than 2 m, Al4 [Si4O10] (OH) 8. Because of its hydrous aluminosilicate chemical composition, layered structure and particle size, it has many special properties which are not available in general minerals. The extensive use of kaolin is inseparable from its excellent physical properties. Pure kaolin with high whiteness, soft and easy to disperse suspended in water, refractoriness physicochemical performance, good plasticity and high adhesion, excellent electrical insulation properties and the acid solution, good low cation exchange capacity, high.
Q:Is kaolin poisonous? What is kaolin?
Add: kaolin composition is very complex, the chemical composition contains a large number of AL2O3, SiO2 and a small amount of Fe2O3, TiO2, as well as trace amounts of K2O, Na2O, CaO and MgO.
Q:The building is kaolin. Does it have radiation? District 15 years ago is a kaolin processing plant, there will be residual radiation it?
There is no radiation pollution in kaolin itself, but it is impossible to be consistent with the background radiation intensity according to the soil and rock composition in different areas. In other words, the radiation intensities of kaolin and kaolin are not exactly the same. Specific to your place is excessive radiation, and nothing to do with kaolin itself.
Q:What are the differences between kaolin and kaolin? What are the chemical constituents?
Effects: 1., firing pottery,.2. firing pottery or coarse porcelain kaolin
Q:High silica kaolin is?
Silica is our country begin to realize and a new non metallic mineral found in early 80s. It is a relatively high degree of diagenesis, fine particles, containing siliceous argillaceous rock, a certain amount of calcium magnesium, after weathering and leaching, leaching of calcium magnesium is, very fine quartz and clay minerals are preserved down, thus forming a large porous siliceous rocks. It is in alpha, microcrystalline cryptocrystalline quartz, clay minerals as powder or lump, porous siliceous industrial mineral aggregates.
Q:How are laterite and kaolin weathering crusts formed respectively?
Humidity is relatively large, precipitation is relatively large environment, easy to do so, mainly in the equator and nearby areasThe area is high humidity, precipitation, and so the soil organic matter and +1, -1 ions, as well as easy to drain ingredients are leached by water, bring out the ecosystem, and the rest are mainly strong oxidation of iron, magnesium and other oxides
Q:What are the uses of calcined kaolin?
At present, the global total output of about 40 million tons of kaolin (the data belonging to the simple country and production together, in which no statistical ore trade volume, including more repeat calculation), which is about 23 million 500 thousand tons of refined soil. Paper making is the largest consumption Department of refined kaolin, accounting for about 60% of total consumption of kaolin. According to data provided by Temanex consulting Canada, the total output of paper and paperboard in the world was about 319 million tons in 2000, and the total amount of kaolin used in the world's paper coating was about 13 million 600 thousand tons. For general cultural paper, the amount of filling accounts for 10-20% of the weight of the paper. For coated paper and paperboard (mainly light weight coated paper, coated paper and coated paperboard), in addition to filling, pigments are required, and the proportion of kaolin used to fill the pigment is 20-35% of the weight of the paper. Kaolin used in paper making, the paper can give good coverage performance and good gloss coating performance, but also increase the paper whiteness, opacity, smoothness and printability, greatly improve the quality of the paper.
Q:How to improve the viscosity of kaolin
Lingshou County Stone Hengda kaolin processing plant produces high-purity kaolin, calcined kaolin, high quality products, complete models, less impurities, plasticity, high viscosity, low thermal conductivity and other characteristics.
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 difference between chemical pure and pure analysis of kaolin?
Optical purity is more suitable for drug manufacture, the higher the purity, the less impurities.
