Detailed Product Description

china clay/calcined kaolin specifications:

High-whiteness:94% min

Particle size(-2um,%):88-92

Oil absorbency(g/100g)63-73

china clay

[Product name]HS-901A Ultra Fine & Super White Calcined Kaolin

[Character and Performance]

The crystal is in laminar structure of pseudo-hexagonal kaolinite platelets.

Super fine particle with narrow distribution, little residue on 325 mesh, and low abrasion;

Great whiteness, covering power and light dispersion;

A good extender of titanium dioxide.

The coating with HS-901A has good performance in water-preserving, fluidity, viscosity and solid content. It can improve the property of paper such as whiteness, smoothness, opacity, ink absorbency, printability and luster. It is similar to Satintone 5HB.


High-quality paper-making such as light-weight coated paper, coated art paper and paper board, and ink, etc.

Q:Do kaolin have blue and cyan?
Kaolin is mainly aluminosilicate, the main component of AL2 (Si2O5) (OH) 4, or written as Al2O3 2H2O 2SiO2
Q:What is the solid content in kaolin index?
Solid content is to put kaolin in a certain amount of water, and when the solution reaches a certain viscosity, the ratio of the amount of kaolin added to the solution should be 70%, which means washed kaolin
Q:What are the requirements for kaolin as refractory material, such as how much aluminum is needed?
Kaolin as refractory material actually plays two roles, one is to improve refractoriness, and two is to improve the body plasticity of refractory material
Q:Will surface treated kaolin be more insulated than untreated?
Kaolin is an insulating material. If it is to increase the insulation of kaolin products, quartz, feldspar, calcite or mica stone should be added. If glaze, the effect will certainly be better.
Q:How can kaolin be removed from iron?
Superconducting electromagnetic iron removal, the effect is very good, but the equipment input and operating costs are very high, a factory in Guangxi bought one, about 24 million yuan, the operating costs are not clear
Q:What is the porcelain glaze porcelain
Porcelain clay is mainly used for the production of porcelain, porcelain clay or kaolin, is the main raw material for ceramics.
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:What kind of pottery does kaolin need?
Kaolin is only one of the raw materials of ceramics, process ceramics and building ceramics for kaolin requirements are different, depending on the manufacturer's raw materials requirements.
Q:How to improve the viscosity of kaolin
Businessmen can follow close feeding according to the characteristics and viscosity of kaolin, thereby improving the recovery performance of ceramic products, so as to ensure no cracking, high temperature calcining without deformation, improve the success rate of ceramic shaping. At the same time, in the process of making porcelain blank, it is possible to increase the stickiness of kaolin and improve the plasticity ability by using manual trampling and trampling of livestock.
Q:Should kaolin be used in polyester production?
But in the process of polyester production, the ordinary polyester fiber can be modified by adding kaolin particles in the spinning solution, thus improving the properties of polyester fiber.
We are a comprehensive mineral product developing enterprise integrating the processes of mining, mine exploring, ore-sorting and deep processing. We have established favorable cooperation with a number of leading coating manufacturers and those well-known papermaking companies at home and abroad. We will keep working hard to provide high quality products and services for our customers.
