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:Can pure kaolin or montmorillonite burn pottery? If not, what do you need to add?
Pure can pottery, such as white is pure kaoline. In addition, according to the needs of different types of ceramic added into material, such as sand pottery in the need to add fine sand, in order to increase the thermal shock resistance performance of pottery. Then such as pottery pottery pottery, these different colors are made by feeding and then control the roasting conditions.
Q:Steam is used to open the pores, open the state, with kaolin mask will not plug the pores?
No, kaolin is clean. When you wash your face, use a sponge. Oh, it's best to use a sponge with a bumpy hole, so it's clean
Q:How to improve the viscosity of kaolin
Lingshou County Stone Hengda kaolin processing plant produces high-purity kaolin, calcined kaolin, high quality products, complete models, less impurities, plasticity, high viscosity, low thermal conductivity and other characteristics.
Q:What's the difference between kaolin and kaolin?
(kaolin) also called Gaoling reservoir soil, white clay, clay soil, Yang (porelain clay). The main component is aluminum silicate hydrate (A12O3.2SiO2.2H2O). The color white or grayish, a hexagonal flaky crystal, the relative density is 2.54 ~ 2.60, oil content is 30% ~ 50%. kaolin pH value is generally 4 ~ 5. A weak acid.
Q:In the paint, paint, ink, imported washed kaolin can replace part of titanium dioxide?
Can replace part of titanium dioxide, specifically the imported kaolin is high mesh products, and close to the fineness of titanium dioxide. Can help disperse titanium dioxide. In actual use, no wet zhegaili, easily dispersed, can be used as a physical fitness pigment, reduce the cost.
Q:Is the kaolin used in Longquan celadon?
Now the personal development of Longquan celadon think it should be a new peak in the history, many artists are celadon constantly exploring new ideas, new technologies, new materials, new technology, and used kaolin as material although not before in history, does not mean that now is not authentic. And kaolin can make the price close to the people the porcelain white porcelain, Bone China has such a sense of vision, it is not so bad. Now, pure handicraft Longquan celadon products usually use traditional cinnabar and iron tire.
Q:Is kaolin soluble in water?The dispersion of kaolin in water is very unstable,At least stable 5-6 hours
Kaolin is not water-soluble and can not be dissolved in waterIn the water to be stable, first of all need to fine kaolin (small particles), but also to add stabilizers and so on
Q:How to remove the kaolin from the stone?
Kaolin has strong acid resistance, but its alkali resistance is poor. Try using this nature!
Q:How many eyes does the inner wall latex paint kaolin use?
Paint. (Emulsion), also known as synthetic resin emulsion coating, is a kind of organic coatings, is based on synthetic resin emulsion as base material, adding pigments, fillers and various additives made up of a kind of water-based paint. According to the production of different raw materials are mainly polyvinyl acetate latex paint latex paint, acrylic latex paint, pure acrylic and styrene acrylic latex paint and other varieties. According to the product applicable environment is different, divided into interior wall emulsion paint and exterior wall latex paint two kinds. According to gloss decoration can be divided into light, matte, semi light, mercerizing and other types of light. Latex paint has many advantages different from traditional wall paint, such as easy to brush, dry and so on. The methods of identifying latex paints are looking, smelling, wiping, brushing, pulling, and testing.
Q:Is kaolin a soil or a rock?
Commonly known as kaolin clay, kaolinite or halloysite is the main mineral components of soft clay. Named after the first discovered in Jingdezhen 45 km east of the East mountain.
