Detailed Product Description

kaolin clay/calcined kaolin specifications:

High-whiteness:93.5% min

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

Good extender of TiO2

kaolin clay/

calcined kaolin HS-801A

[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.

It is similar to Satintone W.

[Application]

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

Q:What's the requirement of high-grade kaolin?: Whiteness is one of the main parameters of kaolin's technological properties. Kaolin with high purity is white. Kaolin whiteness, natural whiteness, and degree of self calcination. For ceramic raw materials, the whiteness after burning is more important. The higher the calcination whiteness, the better the quality. The ceramic process stipulates that the drying temperature is 105 degrees centigrade and the classification standard is the natural whiteness. The calcined 1300 DEG C is the grading standard for the whiteness of the calcined products. Whiteness can be measured by a whiteness meter. A whiteness meter is a device for measuring the reflectivity of light at 3800 7000A wavelengths. In the whiteness meter, the reflectance of the sample to be measured is compared with that of the standard sample, that is, the self - value.

Q:How to distinguish kaolin?: Therefore, kaolin has become the necessary mineral material for dozens of industries, such as paper making, ceramics, rubber, chemicals, coatings, pharmaceuticals and national defense. Kaolin is widely used in the paper making industry. There are two main areas. One is used in papermaking (or paper making), and the other is the pigment used in the surface coating process. Kaolin was first discovered in china.

Q:In the paint, paint, ink, imported washed kaolin can replace part of titanium dioxide?: Paint and paint can be partially replaced, but it can affect whiteness and covering ability. Too much addition will make paint / paint a plastic fluid.Ink can not be replaced, because it will affect the rheological properties of the ink (become plastic circulation, is not conducive to printing).

Q:How to distinguish the good or bad of kaolin?: Kaolin is based ceramic preform molding, has good plasticity and binding, can effectively reduce the deformation and cracking of the embryo, with high fire resistance and burning degree, can enhance the mechanical strength, can improve the thermal stability and chemical stability and sintering properties, good suspension property and adsorption in ceramics in the process of color glaze. The product also has three oxidation, two aluminum content, high iron, manganese, titanium and other harmful impurities, low ore, ore and concentrate quality stability, etc., is a high quality kaolin.

Q:How to distinguish bone porcelain and kaolin porcelain?: Permeability: causes of bone porcelain production formula itself has an important external characteristic is the permeability, but this feature is not China's proprietary, on the market of shell porcelain and white porcelain (kaolin porcelain), pearl porcelain as long as do some thin, but also the existence of permeability, permeability and bone but they are different, for the customer, the bone china into a light bulb to see, bone meal with high content of Fine Bone China is wholly transparent, low content of bone and other bone china porcelain that has the obvious difference in the permeability effect. Moreover, the porcelain of the same thickness, the permeability of Bone China is much higher than similar porcelain.

Q:How are laterite and kaolin weathering crusts formed respectively?: Minerals on the earth are mainly divided into three types of energy minerals, metal minerals and non-metallic minerals, kaolin is an important non-metallic mineral, and mica, quartz, calcium carbonate and called the four major non-metallic mineralsSmall flake, tubular, laminated and kaolinite mineral kaolin is mainly composed of a cluster of less than 2 microns (kaolinite, dickite, nacrite, halloysite etc.), chemical formula and ideal for AL2O3-2SiO2-2H2O, the main mineral is kaolinite kaolinite and water, in addition to kaolinite cluster mineral, montmorillonite, and Ye Lashi, illite, quartz and feldspar and other minerals. The associated chemical composition in the kaolin contains large amounts of AL2O3, SiO2 and a small amount of Fe2O3, TiO2, Na2O, K2O and trace amounts of CaO and MgO.The origin of the name of the kaolin is very interesting, it is said that at the beginning of eighteenth Century, the French priest Pillay Delecre in his "China porcelain manufacturing" in one book, first with a name called "Gaoling" village near Jingdezhen named China clay, which translates as "kaolin", then gradually spread widely cited people that became an international term.

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:Kaolin with magnetic separator, how about iron?: This is a permanent magnet product, characterized by low energy consumption and stable performance. It has certain advantages in the production of ceramic raw materials for iron removal. This equipment used in our side a lot of good results, with electromagnetic products, the use of better results.

Q:Is kaolin soluble in water?The dispersion of kaolin in water is very unstable,At least stable 5-6 hours: Kaolin is not water-soluble and can not be dissolved in waterIn the water to be stable, first of all need to fine kaolin (small particles), but also to add stabilizers and so on

Q:What is the difference between diatomite and kaolin? Thank you: The special porous structure of natural diatomite can be observed under microscope, and the microstructure of diatomite is the characteristic of physical and chemical properties of diatomite.
