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: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:High silica kaolin is?
High silica (also known as quartz, silica, silica, silicone soft soil, amorphous silica, Tripoli, powder, quartz). A SiO2 ore containing pure natural particulate silica powder. No brittle plasticity, the powder is not hydrophilic, strong acid resistance, differential thermal analysis of typical quartz the differential thermal curve, refractoriness 1750 ~ 1832 degrees. For ceramics, porcelain, glazed tile, fine ceramics, glass, paint, rubber filler and refractory materials, and can be used as fine abrasive, polishing material and precision casting sand. Silica 98.87%, ferric oxide 0.04%, two aluminum oxide 0.67%. three
Q:China clay, kaolin clay, three what is the difference? Is China clay is kaolin chemical elements of the three specific? What is the difference?
Also known as clay kaolin, clay is composed of metamorphic mica and feldspar.
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?
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. There are reports that Japan has also used kaolin instead of steel, cutting tools, lathes, drills, and internal combustion engines. Especially in recent years, the rapid development of modern science and technology, the application of kaolin is more extensive, began extensive use of kaolin as new materials in some high-tech fields, and even nuclear reactor space aircraft and spacecraft components with high temperature porcelain, made of kaolin.
Q:Kaolin, calcium carbonate, talc, which does not affect the ink gloss?
Calcium carbonate is a kind of inorganic compounds, commonly known as CaCO: limestone, limestone, limestone, marble etc.. Main ingredients: calcite, is a kind of compound, chemical formula is CaCO, neutral, basically insoluble in water, soluble in hydrochloric acid. It is common on the earth substances exist in aragonite, calcite, chalk, limestone, marble, Shi Huihua rock, also is the main component of animal bones or shell. Calcium carbonate is an important building material and is widely used in industry. Calcium carbonate is composed of calcium and carbonate ions combine to form, so it is also calcium carbonate.
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 kind of pottery does kaolin need?
Kaolin is only one of the raw materials of ceramics, process ceramics and building ceramics for kaolin requirements are different, depending on the manufacturer's raw materials requirements.
Q:Are there any differences between bentonite and kaolin?
Bentonite (Bentonite) predominantly montmorillonite aqueous clay minerals. The chemical composition of montmorillonite: (Al2, Mg3) Si4O10 OH2 nH2O, because it has special properties such as swelling, adhesion, adsorption, catalysis, thixotropy, suspension and cation exchange. So widely used in various industrial fields.
Q:Barium calcium carbonate kaolin which zhegaili better
Talc powder, English name PULVISTALCI, white or white like, fine, sand free powder, hand touch greasy. Odorless, tasteless. This product is insoluble in water, dilute ore, acid or dilute hydrogen alkali solution.
Q:How to distinguish between light calcium carbonate and calcined kaolin?
Kaolin is a nonmetallic mineral, a kind of clay and clay rock mainly composed of kaolinite group clay minerals. [1] from Jiangxi province Jingdezhen Gaoling village name.
