Detailed Product Description

paint grade calcined kaolin specifications:

High-whiteness:93.5% min

Particle size(-2um,%):80-84

Good extender of TiO2

paint grade calcined kaolin

[Product name]HS-801A Ultra Fine & Super White Calcined Kaolin

[Character and Performance]

HS-801A calcined kaolin giving very high opacity, high whiteness, fine particle, good dispersion, little residue on 325 mesh sieve,Super whiteness, good light dispersion ,fluidity and chemical stability, dont react with other solvents, good floatability against sedimentation. HS-801A is a very effective opacifying extender in , partially replacing TiO2, reducing the overall cost of paint formulations but maintaining paint film quality.It can improve the properties of paints such as scrub resistance, abrasion endurance, ageing resistance and stability during storage. It is especially necessary in making the paints of low VOC and high solid content.


Widely used in high-quality paints such as emulsion paint, powder coating, oily paint, etc.

Q:What are the requirements for the whiteness of calcined kaolin in the coating formula?
Whiteness stability is very important, if the Baidu volatility assembly affects the optical properties of the coating, resulting in the same batch of products obvious color difference.
Q:What's the difference between Ye Lashi and kaolin?
The main components of both are Si and Al compounds. The main difference is that the content of the main components is different. The content of Si and Al of kaolin is close to that of kaolin, and the amount of burning of kaolin is relatively large;
Q:What is kaolin?
1. brightness and brightnessWhiteness is one of the main parameters of kaolin's technological properties. Kaolin with high purity is white. For ceramic raw materials, the whiteness is more important after calcination. The higher the whiteness of calcination, the better the quality
Q:Process characteristics of kaolin
Non plasticity <1 viscosity is a characteristic of a fluid that hinders its relative flow due to internal friction. Its viscosity is used to indicate its size (the internal friction force applied to 1 units per unit area). The unit is Pa. S. Viscosity measurements are generally made using rotational viscometer to measure the rotational speed in kaolin slurries containing 70% solids. Viscosity is very important in the process of production. It is not only an important parameter of ceramic industry, but also a great influence on the paper industry. According to data, foreign kaolin as paint, coating at low speed requires viscosity of about 0.5Pa - s, high-speed coating requirements of less than 1.5Pa - S.Thixotropy refers to the characteristics of a fluid that has become gelatinous and no longer flowing. It becomes fluid after stress and gradually becomes intact after being stationary. The size is expressed by a thickening factor and measured by an outflow viscometer and a capillary viscometer.Viscosity and thixotropy are related to the mineral composition, particle size and cation type in the mud. In general, the content of montmorillonite is fine, the particles are fine, and the exchangeable cations are mainly sodium, with high viscosity and high coefficient of change. Therefore, it is often used to increase the viscosity and thixotropy of plastic clay, improve the fineness and so on, and reduce it by increasing dilution, electrolyte and water content. The drying performance of kaolin clay material in the drying process. Including drying shrinkage, drying intensity and drying sensitivity.
Q:Can pure kaolin or montmorillonite burn pottery? If not, what do you need to add?
Kaolin is hard or soft, chemical properties are similar, but the physical properties of different, soft adhesion, plasticity, suitable for ceramics.
Q:Can calcined kaolin be used in PVC tubing?
With the development of the national economy, people pay more and more attention to the deep processing of kaolin, because it can not only obtain new materials with special properties, but also increase the economic benefits. After deep processing of kaolin, it can be used as filler of rubber and plastic and insulating filler of cable.
Q:What is the best composition of kaolin?
Kaolin is mainly aluminosilicate, the main component of AL2 (Si2O5) (OH) 4, or written as Al2O3 2H2O 2SiO2
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:Can the water containing kaolin be drinkable?
The general soil are kaolin containing ingredients, pure kaolin is acidic soil, pH value of about 4-6, the more pure kaolin more acid, general plants to grow, if plants can grow, the water can drink;
Q:What are the differences between kaolin and kaolin? What are the chemical constituents?
(kaolin) also called Gaoling reservoir soil, white clay, clay soil, Yang (porelain clay). The main component is aluminum silicate hydrate (A12O3.2SiO2.2H2O). The color white or grayish, a hexagonal flaky crystal, the relative density is 2.54 ~ 2.60, oil content is 30% ~ 50%. kaolin pH value is generally 4 ~ 5. A weak acid.
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.
