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.

CALCINED KAOLIN FOR COATING Quality Under GB

 


Q:Hard kaolin in the ceramic piece, which is used in which? What's the difference between washed kaolin and washed kaolin?
Whiteness difference is big, generally after light burning, kaolin whiteness will increase, and wash water will not significantly increase whiteness.
Q:Who knows the value of the raw ore of this kind of kaolin? How much is it?
Also, the crude ore is basically worthless, and the parameters after washing are not specific. About 300-500 yuan.
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:What is the porcelain glaze porcelain
The clay is composed of metamorphic mica and feldspar, in which sodium and potassium, calcium and iron loss, water changes into. The glaze is covered in colorless or colored ceramic surface of the glass layer is raw minerals (quartz, feldspar, talc, kaolin etc.) and chemical raw materials according to a certain proportion (part of raw material can be made by grinding glaze frit), applied to the blank surface, under certain temperature and calcining.
Q:Method for separating kaolin
For the separation of quartz, feldspar, kaolin, iron ore, mica titanium minerals and other non clay minerals and organic matter production, which can meet the demand of various industries kaolin products, in addition to the use of gravity separation, flotation and magnetic separation of kaolin was purifying, sometimes using chemical bleaching and stripping, ultra-fine calcined surface modification processing method for processing of kaolin. The processing of kaolin is divided into two processes, dry process and wet process.

(1) dry process, usually the ore will be broken through the crusher to about 25mm, to the cage crusher, the particle size reduced to about 6mm. The crushed ore is further ground by a blown Raymond Mill equipped with a centrifuge and cyclone dust collector. The process can remove most of the sand and gravel, and is suitable for processing ores with high whiteness, low sand content and suitable particle size distribution. Dry processing is of low cost and is usually used as a low filler for rubber, plastics, and paper making industries.

Q:How to identify kaolin?
Kaolin can soluble in water but not completely dissolved, hands have smoothness, without kaolin with high moisture content and acid, usually bluish white rice and white
Q:Kaolin 200 mesh powder what does that mean? Is the eye powder the higher the better?
The higher the number of the finer particles. Fineness theory should be the finer the better, but the more fine processing costs, so we should consider procurement costs, enough on the line.
Q:What is the difference between porcelain stone and kaolinite?
It is the name for the two rock albite diorite or albitite, weathered soil known as porcelain clay, porcelain stone ceramics containing AI2O316% SiO272%. porcelain stone as ceramic raw materials can be made of porcelain alone, can also be used as ingredients instead of potassium feldspar porcelain stone. Superfine grinding and surface modification of the glaze made of deep processing and fine powder materials and composite materials, widely used in ceramics, plastics, rubber, paper and other fields.
Q:Which mixer can be more evenly dispersed kaolin slurry?
If you love to drink fruit juice drinks of all kinds, so it is recommended to select with mixer speed regulation, so that you can freely adjust the stirring speed, some fruit juice does not need to stir too broken to drink. Therefore, you can choose a mixer with speed control function.
Q:What is the difference between diatom mud and kaolin?
Kaolin is a nonmetallic mineral, a kind of clay and clay rock mainly composed of kaolinite group clay minerals.
