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.

[Application]

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

Q: High silica kaolin is?: High silica (also known as quartz, silica, silica, silicone soft soil, amorphous silica, Tripoli, powder, quartz). A SiO2 ore containing pure natural particulate silica powder. No brittle plasticity, the powder is not hydrophilic, strong acid resistance, differential thermal analysis of typical quartz the differential thermal curve, refractoriness 1750 ~ 1832 degrees. For ceramics, porcelain, glazed tile, fine ceramics, glass, paint, rubber filler and refractory materials, and can be used as fine abrasive, polishing material and precision casting sand. Silica 98.87%, ferric oxide 0.04%, two aluminum oxide 0.67%. three

Q: The difference between bauxite, kaolin and clay: The quality standard of kaolin is mainly composed of small, flaky, tubular and laminated kaolinite minerals less than 2 microns. Kaolinite minerals: cluster by kaolinite, dickite, nacrite, halloysite etc., chemical formula and ideal for AL2O3-2SiO2-2H2O, the main mineral is kaolinite kaolinite and kaolinite mineral water, in addition to the cluster, and montmorillonite, illite, quartz and feldspar, Ye Lashi and other associated minerals. Kaolin plasticity, adhesion, certain drying strength, sintering and sintering whiteness and other special properties, make it become the main raw materials Kaolin ceramic ceramic production, is a mainly composed of kaolin clay. The name was first found in kaolin village, northeast of Jiangxi, Jingdezhen province.

Q: Barium calcium carbonate kaolin which zhegaili better: The ink consists of major and auxiliary components, which are evenly mixed and rolled repeatedly to form a viscous, gelatinous fluid. It consists of binder (resin), pigments, fillers, additives and solvents. The fingerprint brush ink surface gloss after drying in the light, the ability to the same concentration of reflected light. Ink with high gloss shows great brightness on printed matter. The glossiness mainly depends on the kind and property of the ink in the ink, the treatment of the refining process in ink making and the smoothness of the ink film after drying. In addition, the ink gloss by nature pigment ink composition, particle size and shape effect of dispersion; ink penetration, leveling, drying properties of the substrate material and so on.

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 characteristics of kaolin in ceramic materials?: The main characteristics of kaolin in chemical composition are high aluminium content and low flux content. Its producing area spreads all over the place, the south is much native kaolin, the north is much more sticky kaolin. Tyre material is porcelain clay (kaolin). Porcelain needs about 1200 degrees to burn.

Q: Is the kaolin used in Longquan celadon?: In fact, the traditional Longquan celadon products is not the pursuit of what body transparent, the so-called "thin eggshell glaze" is to rely on manual trimming, repeated glazing products to shiny jade texture, rather than relying on the original material characteristics to show. You can go to the museum to see the old Longquan celadon products. None of them are made of kaolin.

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.

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: What is the difference between diatom mud and kaolin?: Kaolin is a nonmetallic mineral, a kind of clay and clay rock mainly composed of kaolinite group clay minerals.

Q: The difference between calcined clay and calcined kaolin: Generally speaking, the strengthening effect of hard, clay on hardness, elongation strength, tensile strength or wear resistance is larger than that of soft clayBut the hard clay and soft clay (hard Claysoft clay) is mixed with rubber as raw material mixed hardness, tensile strength training plus sulfur product for compliance, which can not be a clear division, but hard clay particles were relatively small, at 2 below for more than 80%, soft clay is about 50%. The proportion of around 2.6. The general kaolin is acidity, pH value is about 4~5, but also the use of alkali or amine treatment, the pH value tends to alkaline. Kaolin better than calcium carbonate in the tensile strength and hardness increase and mechanical strength has good performance, but the degree of poor white, permanent compression deformation, and sulfur is slow (because of the pH value of 4.5.5, delay the sulfur addition tendency), glycerol, ethylene glycol, can amine (Glycol) as activating agent to improve the properties of sulfur. The clay at suitable temperature (600~800 DEG C) loses water of crystallization calcination (OH) the crystal structure collapse, in order to improve live Because the free ion (ion) is adsorbed and fixed, the insulation effect can be improved, and the treatment can decompose the organic matters and increase the whiteness, and because the size is neat, the dispersion is good
