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:What is the difference between porcelain stone and kaolinite?
- Kaolinite is the main mineral composition of kaolin, weathering crust is common in magmatite and metamorphic rocks. Chinese famous origin are Jiangxi Jingdezhen, Jiangsu kaolinite Suzhou, Hebei Tangshan, Hunan and Liling. The rest of the world famous origin of British Cornwall and Devon, France, the United States of Georgia Irie. Kaolinite is the main raw material for ceramics in other industries, it is also widely used.
- Q:What is the difference between kaolin and rare earth, which is better to use as ceramic? What effect will it have?
- There are many kinds of rare earth including kaolin, such as vegetables, many kinds, including Chinese cabbage. Ceramics do ask the ceramic makers, I'm sorry I don't understand
- Q:The difference between calcined clay and calcined kaolin
- Calcination can also make the crystal structure of kaolin changes (mainly caused by hydrogen bonding and crystal water removal layer), from the original ordered lamellar crystal structure of kaolin into disordered metakaolin, the exposed parts of the original crystal layer group, and due to remove water of crystallization, type and quantity of surface active the increase (the type changed from -OH to Si-O, Al-O and part of the remaining -OH), the reaction activity increased.Calcined kaolin can lead to particle size increased, while the decrease of surface area, adsorption decreased, but the decrease of surface energy, to improve the dispersibility of kaolin, and the amorphous structure became loose, but also can improve the dispersion of calcined kaolin after dehydroxylation. Usually by grinding or fine chemical surface modification as rubber plastic and other reinforcing filler of white smoke.Shvarzman replace some found that when the amorphous phase in the kaolin is more than 55%, according to the ASTM618 standard can be used as an active filler.
- Q:Does the whiteness of washed kaolin mean natural whiteness or whiteness after calcination?
- Whiteness difference is big, generally after light burning, kaolin whiteness will increase, and wash water will not significantly increase whiteness.
- Q:The difference in structure between graphite, talc and kaolin
- 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. This product is magnesium silicate mineral!
- Q:What's the use of kaolin mask powder? How about hot water or cold water?
- Usage method1, wash your face (5 grams): gently and facial skin fusion, wash with water (do not force friction!).2, mask (10-15 grams): full smear on the face, dry before washing (avoid eye and other thin skin).3, shampoo (20 grams): make the batter slowly dissolved, and better integration with the hair.4, bath (150-200 liters of hot water, add 20-40 grams of powder).
- Q:The difference between kaolin and high white mud
- It has good acid resistance, solubility, low cation exchange capacity, good fire resistance and other physical and chemical properties. Therefore, kaolin has become the necessary mineral material for dozens of industries, such as paper making, ceramics, rubber, chemicals, coatings, pharmaceuticals and national defense.
- Q:How to use washed kaolinWashed kaolin in the paper-making process how to use, where China's kaolin more suitable point? Which home is the biggest?
- The pre dispersed good white material and other additives are added together as paper coating preparation for subsequent use. Now the domestic use of paper coating can be applied to most of the above is the Guangdong Maoming Yinhua kaolin, the company is the only company in Guangdong, the first through the ISO certification of enterprises, with more than ten years experience in the production of. Especially high whiteness and high gloss kaolin YH-01 newly developed is being used by many well-known enterprises at home and abroad. The product has good characteristics of high whiteness, easy dispersion, uniform particle size, can greatly improve the printability of paper. All over the country have their own offices, can provide customers with better service.
- Q:What are the colors of kaolin ore?
- Containing Fe2O3 was rose red, brown and yellow; containing Fe2+ was pale blue, pale green with pale brown MnO2;
- Q:What are the difficulties in kaolin beneficiation?
- Kaolin beneficiation important selection of equipment, with what kind of equipment to sorting, it is necessary to experiment to analyze, preliminary analysis in place, as well as how to see the effect
