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 kaolin mask be made directly?
Replenishment mask can be used every day. A good moisturizing mask, adhere to the application will greatly enhance the moisture content of the skin.
Q:Should kaolin be used in polyester production?
Polyester fiber is also called polyester fiber (PET), the basic component is polyethylene terephthalate two ester, molecular formula [-OC-Ph-COOCH2CH2O-]n, so simply do not use kaolin when producing polyester.
Q:Will surface treated kaolin be more insulated than untreated?
The original peak soil has a certain insulation, if you have to deal with, and then compare, it depends on how to deal with.
Q:What kind of pottery does kaolin need?
General ceramics are made of kaolin, different ceramics are only prepared in different proportions of the ingredients page.
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: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?
In the paper, according to their actual situation to kaolin pre dispersed or other materials together in a mixing tank. When in the pre dispersion in dispersion process just add a little dispersant (sodium polyacrylate or other organic dispersant) can achieve the desired results.
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 is the use of kaolin?
Kaolin is a kind of fine grained clay with kaolinite or multi water kaolinite as its main component. It was first discovered in kaolin village near Jingdezhen, china. According to historical records, the village area of the Jingdezhen kaolin clay mining heyday in the early Qing Dynasty, to Guangxu was gradually fading to white and delicate famous open world, as an indispensable raw material for billet. So when the town was used in the name of the village "porcelain industry Gaoling" named for him, producing clay from premises. After the extension of the same, and kaolin kaolin produced by the same place and the purpose of use, are called kaolin, such as stars, kaolin, Fuzhou kaolin, etc..
Q:What are the surface modification technologies of calcined kaolin and the matters needing attention?
Calcined kaolin is a kind of mineral material with high whiteness, large specific surface area, good insulation and good thermal stability, which is calcined, dehydrated and removed volatile substances. Calcined kaolin has excellent chemical corrosion resistance, solvent resistance, acid and alkali resistance and good reinforcing and processing performance, widely used in paints, coatings, paper, rubber and plastic products, cable, ceramics and other industries.
Q:How to distinguish bone porcelain and kaolin porcelain?
(Bone China): also known as referred to as bone china, Bone China, production began in England, the basic process is based on animal bone char, clay, feldspar and quartz as raw materials, a kind of porcelain biscuiting after high temperature and low temperature glaze firing two times.
