CALCINED KAOLIN FOR PAPER MAKING(GB-CK98L/D)

Q: How to use washed kaolinWashed kaolin in the paper-making process how to use, where China's kaolin more suitable point? Which home is the biggest?: The pre dispersed good white material and other additives are added together as paper coating preparation for subsequent use. Now the domestic use of paper coating can be applied to most of the above is the Guangdong Maoming Yinhua kaolin, the company is the only company in Guangdong, the first through the ISO certification of enterprises, with more than ten years experience in the production of. Especially high whiteness and high gloss kaolin YH-01 newly developed is being used by many well-known enterprises at home and abroad. The product has good characteristics of high whiteness, easy dispersion, uniform particle size, can greatly improve the printability of paper. All over the country have their own offices, can provide customers with better service.

Q: High silica kaolin is?: Silica is our country begin to realize and a new non metallic mineral found in early 80s. It is a relatively high degree of diagenesis, fine particles, containing siliceous argillaceous rock, a certain amount of calcium magnesium, after weathering and leaching, leaching of calcium magnesium is, very fine quartz and clay minerals are preserved down, thus forming a large porous siliceous rocks. It is in alpha, microcrystalline cryptocrystalline quartz, clay minerals as powder or lump, porous siliceous industrial mineral aggregates.

Q: What is the difference between chemical pure and pure analysis of kaolin?: Optical purity is more suitable for drug manufacture, the higher the purity, the less impurities.

Q: I only know that is a kind of raw material, and sell them where to sell, and I can have to contact the white mud!: 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. For general cultural paper, the amount of filling accounts for 10-20% of the weight of the paper. For coated paper and paperboard (kaolin ore mainly includes light weight coated paper, coated paper and paperboard), in addition to the packing, also need to fill, pigment, pigment with kaolin accounted for paper weight 20-35%. Kaolin used in paper making, the paper can give good coverage performance and good gloss coating performance, but also increase the paper whiteness, opacity, smoothness and printability, greatly improve the quality of the paper. The main production of ceramic white mud to local sales.

Q: How to distinguish bone porcelain and kaolin porcelain?: Color: China for porcelain powder containing the reason itself has a natural milk white, in other words, with a little yellow, this is a feature of any other kinds are unable to copy out. Kaolin porcelain is pure white.

Q: What is kaolin clay?: The clay used for casting is divided into two categories: plain clay and bentonite according to their mineral composition

Q: Kaolin calcining temperature: The relative density of 2.5-2.6, the main component is alumina and silicon oxide crystal material with different crystal water, chemical formula Al2O3? 2SiO2? 2H2O (crystal water to form hydroxyl groups on the surface of kaolin). The structure: Si (Al) - OH - Si - O - Al - and - Si (Al) O, the activity is on the surface modification of kaolin clay foundation. The pH value is generally about 4-5, acidic, and the crystal structure of the -OH based adsorption accelerant, thus delayed vulcanization effect.

Q: This is a stone dug with kaolin. Does anyone know what it is?: The stones dug together with kaolin are quartzite,

Q: Which mixer can be more evenly dispersed kaolin slurry?: Look at the mixer blade, is an important small details of the selection of mixer, mixer grinding effect is good, all on the blade. Therefore, the choice of blade, it is recommended to choose 4 or more than 5 blades of the blender, so that the intensity of mixing, and the effect of grinding will be better.

Q: What is the significance of the target in kaolin?: The project refers to the kaolin kaolin through the screen mesh. The purpose is defined as the number of holes per square inch mesh. 200 mesh for each square powder particle size known particle size. As the particle shape is very complex, usually there are several screening methods, such as particle size, sedimentation particle size, equivalent volume size, equivalent surface area, particle size and so on.
