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:How to remove iron impurities in kaolin and increase their whiteness
In situ biological bleaching refers to the addition of kaolin at the initial stage of fermentation.
Q:How many eyes does the inner wall latex paint kaolin use?
Now the latex paint is not sand grinding, direct mixing so high mesh 1000 mesh, the price is too high
Q:What is the role of kaolin in plastics? What's the role of kaolin in plastic formulations?
Paint calcined kaolin, whiteness is higher, at least greater than 90%, and some manufacturers will require more than 93%.
Q:How to improve the viscosity of kaolin
Businessmen can follow close feeding according to the characteristics and viscosity of kaolin, thereby improving the recovery performance of ceramic products, so as to ensure no cracking, high temperature calcining without deformation, improve the success rate of ceramic shaping. At the same time, in the process of making porcelain blank, it is possible to increase the stickiness of kaolin and improve the plasticity ability by using manual trampling and trampling of livestock.
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's the difference between kaolin and white mud?
Pure kaolin with high whiteness, soft, easy to disperse in water, suspended in plasticity and good adhesion, high excellent electrical insulation properties; has good acid soluble cationic, low resistance and other physical and chemical properties, better exchange. Therefore, kaolin has become the necessary mineral material for dozens of industries, such as paper making, ceramics, rubber, chemicals, coatings, pharmaceuticals and national defense. Kaolin is widely used in the paper making industry. There are two main areas. One is used in papermaking (or paper making), and the other is the pigment used in the surface coating process.
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:The cosmetic effect of kaolin?
Kaolin is a nonmetal mineral, good quality products for whiteness high component, high temperature resistant, soft texture, good acid and alkali resistance, no stimulation to the skin, and has certain adsorption ability, remove skin dirt, grease on the skin absorption and waste etc..
Q:What's the use of kaolin mask powder? How about hot water or cold water?
Powder dissolution method1. Apply proper amount of powder to the container;2 add cold water or warm water equal to 2 times the powder weight, stir until the paste (cream);3, if the time is enough, you can not stir, put it for 3 minutes, you can get a more slippery feel
Q:Does the whiteness of washed kaolin mean natural whiteness or whiteness after calcination?
Whiteness difference is big, generally after light burning, kaolin whiteness will increase, and wash water will not significantly increase whiteness.
