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:The difference in structure between graphite, talc and kaolin
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.".
Q:The difference between kaolin and talc in rubber
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.".
Q:How do porcelain mud distinguish good or bad?
Compared with the international standard of the kaolinite content Chinese, southern Suzhou and Fujian Longyan kaolin soil Si was significantly more than the commonly used North Datong soil, iron content and mix the raw is significantly larger, but the north and south to kaolin aluminum content than the British standard used for EPK, which also makes the general China porcelain to temperature higher than 1310 degrees, or even close to 1350 degrees, but the mineral composition of kaolin is different, around the mining kaolin component is so different, so that a lot of kaolin with today's porcelain stone in the data has been very close to the standardized production and the western industrialization under the background of different kaolin most of the China, or in the production of kaolin ore deposit by the way.
Q:The difference between calcined clay and calcined kaolin
Generally speaking, the strengthening effect of hard, clay on hardness, elongation strength, tensile strength or wear resistance is larger than that of soft clayBut the hard clay and soft clay (hard Claysoft clay) is mixed with rubber as raw material mixed hardness, tensile strength training plus sulfur product for compliance, which can not be a clear division, but hard clay particles were relatively small, at 2 below for more than 80%, soft clay is about 50%. The proportion of around 2.6. The general kaolin is acidity, pH value is about 4~5, but also the use of alkali or amine treatment, the pH value tends to alkaline. Kaolin better than calcium carbonate in the tensile strength and hardness increase and mechanical strength has good performance, but the degree of poor white, permanent compression deformation, and sulfur is slow (because of the pH value of 4.5.5, delay the sulfur addition tendency), glycerol, ethylene glycol, can amine (Glycol) as activating agent to improve the properties of sulfur. The clay at suitable temperature (600~800 DEG C) loses water of crystallization calcination (OH) the crystal structure collapse, in order to improve live Because the free ion (ion) is adsorbed and fixed, the insulation effect can be improved, and the treatment can decompose the organic matters and increase the whiteness, and because the size is neat, the dispersion is good
Q:In the paint, paint, ink, imported washed kaolin can replace part of titanium dioxide?
8-15% can reduce the amount of titanium dioxide. The color brightness, chroma and saturation effect. It has high chemical inertness and temperature resistance.
Q:Barium calcium carbonate kaolin which zhegaili better
The ink consists of major and auxiliary components, which are evenly mixed and rolled repeatedly to form a viscous, gelatinous fluid. It consists of binder (resin), pigments, fillers, additives and solvents. The fingerprint brush ink surface gloss after drying in the light, the ability to the same concentration of reflected light. Ink with high gloss shows great brightness on printed matter. The glossiness mainly depends on the kind and property of the ink in the ink, the treatment of the refining process in ink making and the smoothness of the ink film after drying. In addition, the ink gloss by nature pigment ink composition, particle size and shape effect of dispersion; ink penetration, leveling, drying properties of the substrate material and so on.
Q:Are there any differences between bentonite and kaolin?
Kaolin is a nonmetal mineral, is a kind of clay mineral mainly kaolinite clay and clay rock. Named for Jiangxi province Jingdezhen Gaoling village. The pure kaolin is white and delicate, soft soil, plasticity and fire resistance and other physical and chemical properties. Its good mineral is mainly composed of kaolinite halloysite, hydromica, illite, montmorillonite and quartz, feldspar and other minerals. 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 used plastics, paint, pigment, grinding wheel, pencil, cosmetics, soap, pesticide, medicine, textile, petroleum, chemical industry, building materials, defense and other industrial sectors.
Q:What is the difference between diatomite and kaolin? Thank you
The special porous structure of natural diatomite can be observed under microscope, and the microstructure of diatomite is the characteristic of physical and chemical properties of diatomite.
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.
Q:What kind of kaolin can burn glazed tiles?
So you say the kaolin can burn tile, my answer is yes, but not necessary. A. can is because 1 tons of glazed tile clay, adding 1 kg of kaolin does not affect the product, but the reason is not necessary is to increase the cost of intangible kaolin.
