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: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:Is it near the clay ore
- Magnetite and hematite deposit in native rock, mica, feldspar is there very little, it is difficult to become China clay resourcesOnly the limonite is weathering secondary ore, mica, feldspar will resident may be near, the clay;
- Q:Kaolin, calcination and washing what is the difference between the best, you can talk about it in detail,
- Calcination is through high temperature burning, the role is to kaolin crystal water and organic compounds burned, and improve whiteness and purification
- Q:Where are the main differences between kaolin and kaolinite?
- Kaolin is a nonmetallic mineral, a kind of clay and clay rock mainly composed of kaolinite group clay minerals. Because of the white and delicate, also known as "white cloud soil.". [1] was named after kaolin village in Jiangxi, Jingdezhen province.Its pure kaolin is white, fine and soft, and it has good plasticity and fire resistance. The mineral composition is mainly composed of mineral kaolinite, halloysite, illite, illite, montmorillonite and quartz, feldspar etc.. Kaolin is widely used, mainly used for papermaking, ceramics and refractories, secondly used in coating, rubber filler, enamel glaze and white cement raw materials, a small amount of paint, paint, plastic, used for grinding wheel, pencil, soap, cosmetics, pesticide, medicine, textile, petroleum, chemical industry, building materials, defense and other industrial sectors.
- Q:What is kaolin clay?
- The clay used for casting is divided into two categories: plain clay and bentonite according to their mineral composition
- Q:How to identify kaolin?
- Washed out kaolin can produce many unexpected consequences when used in the deployment of other raw materials.
- Q:The difference between kaolin and calcium carbonate
- Then the carbonation of lime milk to produce calcium carbonate carbon dioxide precipitation, finally by dehydration, drying and crushing the system, or first with sodium carbonate and calcium chloride to precipitate calcium carbonate metathesis reaction, followed by dehydration, drying and crushing the system.
- Q:Should kaolin be used in polyester production?
- Some studies show that under certain conditions, adding kaolin inorganic particles of polyester fiber still has good spinnability and hygroscopicity, dyeability are improved, and has certain anti UV properties. However, the mechanical properties of modified polyester fiber declined due to the decrease of crystallinity.
- 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:Can kaolin mask be made directly?
- Lolita cocoa hydrating moisturizing mask in Switzerland, with apricot ingredients can quickly pay a short time, can quickly repair damaged cells, nourish the dense, into the stream of water to the skin, good effect lasting moisture, can use every day, especially suitable for mixed and dry skin.
