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:How to identify kaolin?
Washed out kaolin can produce many unexpected consequences when used in the deployment of other raw materials.
Q:High silica kaolin is?
Is not the same. Kaolin three two aluminum oxide content is relatively high, high silica silica content is relatively high.The content of three oxidation and two aluminum in kaolin is 22-28%.
Q:What is the difference between chemical pure and pure analysis of kaolin?
Optical purity is more suitable for drug manufacture, the higher the purity, the less impurities.
Q:Application of kaolin
Because the calcined clay oil absorption value is relatively high, so the cosmetics industry recommends the use of ultrafine and high pure water wash soil, strict attention purity and heavy metal content of kaolin, these two aspects report report analysis and detection of heavy metals and chemical products, through the data report and compare its cosmetic requirements can be judged. Pharmaceutical industry bigger user base for butyl rubber plug industry, can use 1250 or so of calcined soil, this is more commonly used, usually as long as the heavy metal test qualified can use. The above two industries use kaolin price difference is quite big, the cosmetics class import product approximately RMB6 yuan /kg, the medicine class RMB2.2 yuan /kg.
Q:What is the difference between kaolin and rare earth, which is better to use as ceramic? What effect will it have?
Kaolin is a representative of clay, commonly used in glazes, which can increase whiteness and provide suspension and adhesion
Q:Steam is used to open the pores, open the state, with kaolin mask will not plug the pores?
With a small spoon to make two small spoon seaweed to small bowl, then add 1:4 water or Zogu water, 1 teaspoon of seaweed plus 4 spoon of water, mixing water at the same access mask stick to beat the egg, then you will find algae release a lot of collagen out oh.
Q:What are the uses of calcined kaolin?
At present, the global total output of about 40 million tons of kaolin (the data belonging to the simple country and production together, in which no statistical ore trade volume, including more repeat calculation), which is about 23 million 500 thousand tons of refined soil. Paper making is the largest consumption Department of refined kaolin, accounting for about 60% of total consumption of kaolin. According to data provided by Temanex consulting Canada, the total output of paper and paperboard in the world was about 319 million tons in 2000, and the total amount of kaolin used in the world's paper coating was about 13 million 600 thousand tons. For general cultural paper, the amount of filling accounts for 10-20% of the weight of the paper. For coated paper and paperboard (mainly light weight coated paper, coated paper and coated paperboard), in addition to filling, pigments are required, and the proportion of kaolin used to fill the pigment is 20-35% of the weight of the paper. Kaolin used in paper making, the paper can give good coverage performance and good gloss coating performance, but also increase the paper whiteness, opacity, smoothness and printability, greatly improve the quality of the paper.
Q:Is kaolin poisonous? What is kaolin?
Kaolin is a nonmetal minerals, the Baidu encyclopedia can know, no toxic poison, this is to say, it is not toxic, but now after a lot of chemical bleaching process, generally acidic, a little.
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:What are the colors of kaolin ore?
Contains the quality is pale yellow, gray, green, black and other colors. The presence of these impurities, reduced the natural whiteness of kaolin, in which iron and titanium minerals will also affect the whiteness of the calcined, porcelain stains or scars appear.
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.
