Q:Are there any differences between bentonite and kaolin?: Kaolin is a nonmetal mineral, is a kind of clay mineral mainly kaolinite clay and clay rock. Named for Jiangxi province Jingdezhen Gaoling village. The pure kaolin is white and delicate, soft soil, plasticity and fire resistance and other physical and chemical properties. Its good mineral is mainly composed of kaolinite halloysite, hydromica, illite, montmorillonite and quartz, feldspar and other minerals. Kaolin is widely used, mainly used for papermaking, ceramics and refractories, secondly used in coating, rubber filler, enamel glaze and white cement raw materials, a small amount of used plastics, paint, pigment, grinding wheel, pencil, cosmetics, soap, pesticide, medicine, textile, petroleum, chemical industry, building materials, defense and other industrial sectors.

Q:What is the difference between diatom mud and kaolin?: Diatom mud is the diatom after the death of the diatom plants in the sea. The diatom formed by the precipitation of the corpse for thousands of years. It forms diatomite after the diatom ore is purified, and the diatom mud can be formed on the upper wall after processing according to the formula proportion.

Q:How can clay sculptures not be cracked and preserved for a long time?: Unless you do otherwise could not crack with sludge, we do things often water and with a damp cloth and plastic cloth, or not how long will crack, another way is to turn out. China ancient sculptures are not easy to crack because it has very strong technology, the mud and gum. What are mixed together, do not remember the specific, there is no such process.

Q:Application of kaolin: Kaolin has become the mineral material necessary for papermaking, ceramics, rubber, chemicals, coatings, pharmaceuticals and national defense.Ceramic industry is the earliest and larger amount of kaolin. The general dosage is 20% to 30% of the formula. The role of kaolin in the ceramic is conducive to the introduction of Al2O3, mullite, the chemical stability and sintering strength during sintering kaolin decomposition of mullite, the main frame form body strength, can prevent the deformation of the product, the firing temperature becomes wide, can make the body with whiteness some. At the same time, kaolin has a certain degree of plasticity, adhesion, suspension and binding capacity, given the enamel porcelain clay, good formability, the ceramic clay for car billet and grouting, easy forming. If used in an electric wire, insulation can be increased and dielectric loss is reduced.

Q:How to remove iron impurities in kaolin and increase their whiteness: The types of pigment ions are different, and the reagents and methods used are different:1, the surface of the adsorbed kaolinite is Fe3+, that is, when iron exists in the form of Fe2O3, the reaction of Fe3+ with Na2S2O4 is reduced to two valent iron salt, which is removed by rinsing and filtering;2, when the adsorption ion is Fe2+, that is iron in the form of FeS2, the oxidant should be used and its reaction, the oxidation of soluble ferrous sulfate and ferric sulfate, so that it can be washed away colorless oxides;3, the majority of samples containing both Fe3+ and Fe2+, the oxidation reduction combined bleaching method, first with the oxidant and reducing agent will become Fe2+ Fe3+ its reduction to Fe2+. Removed by rinsing, filtering, etc.

Q:Who knows the value of the raw ore of this kind of kaolin? How much is it?: There are many important ingredients in kaolin, such as iron and titanium, and many physical indicators!

Q:Which mixer can be more evenly dispersed kaolin slurry?: If you need to stir some hard foods, such as ice like, need to add the juice stir together, it is recommended to select a large power mixer, power stirring power will be stronger and stronger, stir hard foods are also easier and less laborious. So, it is best to choose power at 700W power mixer, will be more dynamic.

Q:Does kaolin ore hazard do harm to human body?: Kaolin is a major component of clay minerals. It is rich in silicon, zinc, magnesium, aluminum and other minerals. The chemical elements are simple: AL4 (Si4O10) OH6, in addition to alumina, silica is also included.

Q:There is a kind of kaolin powder used for making cables. It does not sink in water. It does not damp with a stick. It wants to know what is added in it: I estimate that this has been modified by kaolin powder, and is modified by aluminate, the aluminate by high speed modifier modified kaolin is insoluble in water, and suspension.

Q:What are the colors of kaolin ore?: The color of kaolin is mainly related to its metal oxides or organic matter.
