Q:Is kaolin soluble in water?The dispersion of kaolin in water is very unstable,At least stable 5-6 hours
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. The paper industry is the largest consumption Department of refined kaolin, accounting for about 60% of the 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.
Q:How to distinguish the good or bad of kaolin?
Kaolin chemical composition analysis laboratory test kaolin composition is very complex, kaolin chemical composition contains a large number of AL2O3, SiO2 and a small amount of Fe2O3, TiO2, and trace amounts of K2O, Na2O, CaO and MgO.
Q:The difference between kaolin and high white mud
Pure kaolin is characterized by high whiteness, soft quality, easy dispersion, suspension in water, good plasticity and high cohesiveness, and excellent electrical insulation performance;
Q:Method for separating kaolin
In order to prepare coating grade kaolin products, stripping of thicker layered kaolin must be made into thin sheets. Stripping methods include wet grinding, extrusion and chemical soaking. The wet grinding method will be made about 40% gas solid kaolin slurry, adding dispersant, adding grinding medium (such as quartz sand, porcelain beads, glass beads, nylon polyethylene beads) grinding machine, grinding and sieving after a certain period of time, the precipitation is. Extrusion method will be kaolin pulp sent to the high-pressure pulp mixer, the high-pressure paste pressure to 20 ~ 35Mpa, and then sprayed by the nozzle, due to sudden pressure drop, so that kaolin crystal laminated loose". High speed slurry ejected into the impeller, suddenly change the direction of movement, so that loose crystal lamination peeling. The chemical immersion method using urea solution soaked kaolin powder, and heated to 30 to 80 DEG C, adding a small amount of dispersant, the kaolin fully dispersed, high-speed stirring, so that the crystal layer peeling. Benzidine and acetamide can also be used instead of urea. The neutral water solution of AlCl3 is mixed with Na2SiO3 according to the ratio of 1 to 0.75 to 1 to 5 to produce precipitation.
Q:How to remove the kaolin from the stone?
Ordinary stone mainly silicate compound, hard texture and resistance to acid and alkali; and kaolin molecular formula Al2O3-2SiO2-2H2O, whether or not alumina, silicon oxide, alkaline, so only a small amount of NaOH can be removed through kaolin;
Q:Can calcined kaolin be used in PVC tubing?
At present, calcined kaolin has been widely used in ceramics, rubber, plastics, artificial leather, cement, refractory materials, chemical industry and agriculture.
Q:This is a stone dug with kaolin. Does anyone know what it is?
Kaolin is by weathered granite and granite residual weathering, these residues, can be seen as granite in bones. A small hard rock in a granitic body that is hard to weathered.
Q:How can we tell if there's kaolin in that hill?
Having plasticity; wet soil can be molded into various shapes without breaking, and can remain unchanged for a long time.Specific or to pass the test. If you need to test, you can contact me, we analyzed the testing center, the phone is the user name.
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 are the surface modification technologies of calcined kaolin and the matters needing attention?
The surface modification of calcined kaolin should be done by heating the calcined kaolin in order to react with silane coupling agent and requiring kaolin to maintain a certain temperature in the dynamic state. Only in this way can the excess water in the reaction process and reaction be removed so as to form a stable and firm covalent bond with kaolin. Therefore, it is necessary to determine the surface modification process according to the mechanism of surface modification.
We make good use of kaolin resources when exploring the coal fields. In conclusion, we can cut down the cost of resources by 80%. Meanwhile the effective of resources usage can be increased by 200%. Our company will improve the linkage of production and circulation. Faithful team, excellent style of work, fortitude nature, professional goods and delicate service will provide our customers with the finest cooperative atmosphere to achieve a win-win result.
