In the construction industry, kaolin is widely used in cement based materials. The Kaolingshi prepared by the proper temperature of fake burning, ultra-fine grinding and other processes is considered to be a new generation of cement concrete admixture, which has a significant effect on the workability, strength and durability of cement based materials. At the same time, they also have a good inhibitory effect on the self-shrinkage and shedding phenomenon commonly occurring in high performance cement-based materials.
In the ceramic industry, kaolin application time is early, the amount is also large, usually can account for 20~30%, kaolin can increase the content of A203 in ceramics, mullite generation process is easier, so as to improve the sintering strength and stability of ceramics 18). When firing ceramics, the decomposition of kaolin Mosong stone is the process of forming a frame, this process makes the ceramic is not easy to aliasing and denaturation, at the same time, the firing temperature range is wider, and the whiteness of the ceramic is improved. At the same time, kaolin itself has plasticity, cohesiveness, suspension, associability and other characteristics, so that the formability of porcelain clay and porcelain sleeve is improved. More conducive to the car, grouting, ceramic forming and other processing.
In the refractory industry, kaolin is commonly used to produce refractory materials because of its good fire resistance. Its products can withstand load at high temperature without deformation. Kaolin as the main component of kaolin, bentonite and bauxite, etc., are collectively referred to as refractory clay according to their use of high temperature resistance. It is a good raw material for refractories. There are two main types of refractory products: firebricks and silicon aluminum fiber cotton. The former has a refractoriness of no less than 1730, and can be made into firebricks of various sizes and shapes as needed. The latter is a lightweight refractory thermal insulation material, which is roasted at 1000~1100°C by Kaolingshi, and then the ore is melted by an electric arc furnace at 2000°C, and blown into cotton under high speed air flow.

In the plastic industry, kaolin is mainly used as filler. Because the kaolin after false burning has a large adsorption area and activity, it is applied to plastics, which can adsorb conductive ions in plastics, thereby improving the performance of plastics, making plastics more flat and beautiful, and enhancing the ability to resist chemical corrosion. In the plastic industry, kaolin can replace white powder and be used as pigments. The optical properties of the plastic are not significantly reduced. The addition of Kaolin in the plastic heavy film can reduce the influence of infrared nodes. The absolute green scheduling of the plastic will be improved after the addition of Kaolin. Promote the thermal insulation effect of agricultural film.
In the coating industry, kaolin has long been used as a filler for coatings and paints because of its white color, low price, good fluidity, stable chemical properties, and large surface cation exchange capacity. Kaolin can be used to improve the coating drama, coating system storage stability, coating moisture resistance and impact resistance and other mechanical shadow, pigment resistance to floating color and hair. With the development of production, the requirements for the performance and durability of the coating are increasingly strict, such as the preparation of low VOC, high solid coating, thinner and non-defective smooth, bright coating film, at this time, it is necessary to use Kaolin as an additive. Kaolin CAN adapt almost ALL coating systems from primer to topcoat, all solid composition, coating thickness and gloss.
In the rubber industry, kaolin is often used as a filler to fill the rubber colloid mixture, which can increase the chemical stability, wear resistance and mechanical strength of the rubber, prolong the hardening time, but also can improve the rheology of the rubber, mixing, thinning, improve the viscosity of the non-fluidization products, prevent the sag, collapse, sag, deformation, flat tube and so on. The water resistance, permeability, fire resistance and chemical activity of Kaolingshi rubber products have also been greatly improved. At the same time, kaolin can also be used as a filler in rubber, which can greatly reduce the cost without affecting the performance of rubber.

In the cable industry, due to the production of high absolute green performance cable requires excessive addition of electrical performance improver, and Kaolin Shi as the only product that can be made into electrical performance improver, the prospect is naturally good, in the requirements of high electrical insulation performance of plastic cable and absolute green materials, need to add political false burning kaolin Shi, kaolin after the appropriate temperature sintering has a very high resistivity, Different burning temperature of kaolin air rate is not the same, the gap of cable materials in some of the more active harmful ingredients have a certain absorption effect, can improve the cable green: burning kaolin surface modification, can improve its dispersion in polymer materials, enhance the performance of products, can produce a good bonding interface between organic polymer materials – modifier – burning kaolin, So that the burning Kaolin can be evenly dispersed in the cable, play a better bridge role.
Environmental protection new material is also one of the applications of Kaolingshi, Kaolingshi can be used as a synthetic molecular decoration, polymerization complex aluminum, in addition, due to the high content of aluminum in Kaolingshi makes it the main raw material for the production of poly aluminum chloride, polymerization complex aluminum is a new type of purification agent, the process is simple, has good flocculation effect, low price, The residual aluminum content in the treated water is relatively low, which can generate high density meal condensate, fast settling speed, and low corrosion to the equipment. It has been widely used in the treatment of purified drinking water and industrial wastewater. Using KAolings to produce composite aluminum can improve the quality of the corresponding products, and reduce the production cost, less pollution to the environment, and better economic and social benefits. Modified kaolin also has relatively high matrix activity, strong ability to resist heavy metal pollution, good catalytic activity and selective adsorption performance, so in the process of preparing various catalysts, modified kaolin has become an important filler

The amount of kaolin in the paper industry far exceeds other industries. Kaolinite Duten of the degree of small, after peeling with a good after the tank and sheet form, sheet diameter and size to example large, chemical properties to be used as paper filler and paper coating to improve the gloss of the paper, filling the gap between the paper fiber, improve the opacity and so on. As a filler, it can improve the performance of paper and also reduce costs. As a coating material, it can improve the permeability of paper to ink, inclusiveness and the appearance of paper. The main requirements for kaolinite in papermaking are particle size and impurity content, requiring particle size less than 2um and whiteness greater than 86%.
Aluminum is the main component and one of the decisive factors of kaolin. The presence of aluminum makes Kaolingshi have excellent plasticity and adsorption properties, and it is an indispensable raw material for ceramics, paper making and other industries. Silicon aluminate formed by silicon element and aluminum is one of the components of kaolin. The presence of silicon makes kaolin have good fire resistance, which is suitable for metallurgy, building materials and other fields. There are more iron elements in Kaoling ten, which can affect its color. The iron elements that affect the color are mainly trivalent iron and quadvalent iron. At the same time, kaolin also contains a small amount of calcium, potassium, sodium and other elements, these elements can adjust the pH of kaolin, stability and adsorption and other properties. However, kaolin may also contain impurities such as iron, manganese, sodium, sodium, magnesium and so on. If the content of impurities in Kaolin is too high, it will affect its quality and use effect. The mixed element table in Kaolin ten may be harmful, which will affect the quality of products, especially the color, texture and hardness of returned-capital products. The impurity element table may also change the chemical composition or moisture in Kaolingshi, thus affecting its stability and performance. The impurity elements are harmful substances and pollute the environment. The active purification of Kaolingshi in the production process may contribute to environmental protection. Therefore, when using Kaolin, we need to handle the element content and impurities in kaolin according to different conditions to ensure the quality and use effect of Kaolin, and to protect the environment as much as possible in the production process.
