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: Should kaolin be used in polyester production?
- But in the process of polyester production, the ordinary polyester fiber can be modified by adding kaolin particles in the spinning solution, thus improving the properties of polyester fiber.
- Q: What's the difference between calcined kaolin and washed kaolin?
- First of all, calcined kaolin is calcined, crystalline and raw soil has changed; and washed kaolin is only physical treatment, will not change the properties of raw soil
- Q: The difference between bauxite, kaolin and clay
- The quality standard of kaolin is mainly composed of small, flaky, tubular and laminated kaolinite minerals less than 2 microns. Kaolinite minerals: cluster by kaolinite, dickite, nacrite, halloysite etc., chemical formula and ideal for AL2O3-2SiO2-2H2O, the main mineral is kaolinite kaolinite and kaolinite mineral water, in addition to the cluster, and montmorillonite, illite, quartz and feldspar, Ye Lashi and other associated minerals. Kaolin plasticity, adhesion, certain drying strength, sintering and sintering whiteness and other special properties, make it become the main raw materials Kaolin ceramic ceramic production, is a mainly composed of kaolin clay. The name was first found in kaolin village, northeast of Jiangxi, Jingdezhen province.
- 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: What kind of kaolin can burn glazed tiles?
- Kaolin is a kind of mineral material of better purity. It is not necessary to fire glass tile and kaolin, because glazed tile belongs to coarse pottery, and the quality requirement of clay is not fine
- Q: What's the requirement of high-grade kaolin?
- Whiteness is one of the main parameters of kaolin's technological properties. Kaolin with high purity is white. Kaolin whiteness, natural whiteness, and degree of self calcination. For ceramic raw materials, the whiteness after burning is more important. The higher the calcination whiteness, the better the quality. The ceramic process stipulates that the drying temperature is 105 degrees centigrade and the classification standard is the natural whiteness. The calcined 1300 DEG C is the grading standard for the whiteness of the calcined products. Whiteness can be measured by a whiteness meter. A whiteness meter is a device for measuring the reflectivity of light at 3800 7000A wavelengths. In the whiteness meter, the reflectance of the sample to be measured is compared with that of the standard sample, that is, the self - value.
- 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: Is kaolin poisonous? What is kaolin?
- Composition: non-toxic. Kaolin kaolinite, content accounted for about 90%, the particle size is smaller than 22m, produced in China's Jiangxi province. The name of kaolinite kaolin is widely used in the field of application of ceramics, glass, paper, rubber, daily chemical industry, agriculture and so on.
- 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 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.".
