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: There is a kind of kaolin powder used for making cables. It does not sink in water. It does not damp with a stick. It wants to know what is added in it
- The question about the reform of kaolin can not be explained in one or two words. Remember my name and contact me by telephone.
- 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: High silica kaolin is?
- Silica is our country begin to realize and a new non metallic mineral found in early 80s. It is a relatively high degree of diagenesis, fine particles, containing siliceous argillaceous rock, a certain amount of calcium magnesium, after weathering and leaching, leaching of calcium magnesium is, very fine quartz and clay minerals are preserved down, thus forming a large porous siliceous rocks. It is in alpha, microcrystalline cryptocrystalline quartz, clay minerals as powder or lump, porous siliceous industrial mineral aggregates.
- Q: What kind of kaolin can burn glazed tiles?
- So you say the kaolin can burn tile, my answer is yes, but not necessary. A. can is because 1 tons of glazed tile clay, adding 1 kg of kaolin does not affect the product, but the reason is not necessary is to increase the cost of intangible kaolin.
- Q: Application of kaolin
- Kaolin has become the mineral material necessary for papermaking, ceramics, rubber, chemicals, coatings, pharmaceuticals and national defense.Ceramic industry is the earliest and larger amount of kaolin. The general dosage is 20% to 30% of the formula. The role of kaolin in the ceramic is conducive to the introduction of Al2O3, mullite, the chemical stability and sintering strength during sintering kaolin decomposition of mullite, the main frame form body strength, can prevent the deformation of the product, the firing temperature becomes wide, can make the body with whiteness some. At the same time, kaolin has a certain degree of plasticity, adhesion, suspension and binding capacity, given the enamel porcelain clay, good formability, the ceramic clay for car billet and grouting, easy forming. If used in an electric wire, insulation can be increased and dielectric loss is reduced.
- Q: What is the role of kaolin in plastics? What's the role of kaolin in plastic formulations?
- Paint calcined kaolin, whiteness is higher, at least greater than 90%, and some manufacturers will require more than 93%.
- Q: How to distinguish bone porcelain and kaolin porcelain?
- Voice: the two grade bone china products gently collided, like sweet voice like the sound of wind chimes, and there will be a few seconds of echo, and other kinds of no, also does not have the characteristics of kaolin porcelain.
- Q: What is the significance of the target in kaolin?
- The granularity is particles can be obtained by screen mesh size, with 1 inches (25.4mm) the number of mesh width of the screen mesh representation, so called "mesh". At present, there is no uniform powder particle size standard at home and abroad, and each enterprise has its own definition and representation of particle size index. In different countries and different industries, the screen specifications have different standards, so the meaning of "target" is difficult to unify.
- Q: Kaolin with magnetic separator, how about iron?
- Kaolin separator iron removal process is dry and wet dressing process method for magnetic separation of magnetite, in iron removal process, it can improve the reuse rate in the process of iron removal process, less water consumption, save water, reduce production costs, reduce pollution, dust and dust removal device with special magnetic separation, not air pollution is a kind of high production efficiency, good product quality, no environmental pollution process of creative.
- Q: How are laterite and kaolin weathering crusts formed respectively?
- This soil layer contains very little nutrients, mainly the B layer. (soil profiles can be found)The reason for red clay is that it is red when it is trivalentHow is kaolin formed?Kaolin is a mainly composed of kaolin clay. After fully weathered feldspar, kaolin, quartz and generate soluble salts; then with the rain, the river rafting on it and then re deposition, quartz and soluble salts have been separated, can be accounted for in kaolin kaolin. The largest porcelain is. Good raw material for the production of porcelain.
