Kaolin: Definition & Characteristics

Definition of Kaolin

Kaolin is a non-metallic mineral, a clay and clay rock mainly based on kaolin stone clay minerals. Because it is white and delicate, it is also known as white cloud soil. Its pure kaolin is white and delicate, soft, and has good plasticity and refractory nature. Kaolin is widely used, mainly used for papermaking, ceramic and refractory materials, followed by coatings, rubber fillers, enamel glaze, and white cement raw materials. Pesticide, pharmaceutical, textile, petroleum, chemical, building materials, national defense, and other industrial departments.

Characteristics of Kaolin

Whiteness Brightness
The high-purity kaolin is white. The color of kaolin is mainly related to the metal oxides or organic matter it contained. Generally, it contains FE2O3 with rose red and brownish yellow; it contains FE2+light with blue and pale green; contains MNO2 with light brown. The existence of these impurities reduces the natural whiteness of kaolin. Among them, iron and titanium minerals will also affect the whiteness of burning, causing porcelain to have pigmentation or melting scars.

Plasticity
The mud formed by the combination of kaolin and water can be deformed under the action of external force. After the external force is removed, the nature of this deformation can still be plastic. Plasticity is the basis for the formation process of kaolin in the ceramic body, and it is also the main technical indicator.

Drying Performance
Drying performance refers to the performance of the Kaolin Mud in the process of drying. Including dry shrinkage, dry strength, and dryness sensitivity.
Dry contraction refers to the shrinkage caused by the losing water and drying. The same type of kaolin has different contractions due to different mixing water. Dry strength refers to the folding strength after the mud is dry to the constant weight. Dry sensitivity may produce a tendency to deformation and cracking when the body is dry.

Suspenability
Suspenability refers to the performance that is difficult to precipitate in the water scattered in the water. Generally, the smaller the particle size, the better the suspension. Kaolin, which is used in the enamel industry, requires good suspenability. Generally, the samples scattered in the water have determined the quality of their suspended performance after a certain period of settlement.

What Are Stainless Steel Sheets

The stainless steel sheet has a smooth surface, high plasticity, toughness, and mechanical strength, and is resistant to acid, alkaline gas, solution, and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-free. Stainless steel sheet refers to steel sheet resistant to weak medium corrosion such as atmosphere, steam, and water, while acid-resistant steel sheet refers to steel sheet resistant to chemical etching medium corrosion such as acid, alkali, and salt.

Characteristics of Stainless Steel Sheets

Corrosion Resistance

The stainless steel sheet has the ability to resist general corrosion similar to unstable nickel-chromium alloy. Long-time heating in the temperature range of chromium carbide degree may affect the performance of the alloy in a harsh corrosive medium. It is mainly used for high-temperature applications. High-temperature applications require strong anti-sensitization of materials to prevent intergranular corrosion at low temperatures.

The corrosion resistance of stainless steel sheets mainly depends on their alloy composition and internal structure, and chromium plays a major role. With high chemical stability, chromium can form a passive film on the steel surface to isolate the metal from the outside world, protect the steel sheet from oxidation, and increase the corrosion resistance of the steel sheet. After the passivation film is destroyed, the corrosion resistance decreases.

High-Temperature Oxidation Resistance

All stainless steel sheets have high-temperature oxidation resistance, but the oxidation rate will be affected by inherent factors such as exposure environment and product shape.

How to Select Stainless Steel Sheets

The selection of stainless steel sheet shall consider the operating conditions, such as manual operation or automatic operation, the performance and type of hot press, and the quality requirements for the pressed materials, such as hardness and luster.

In addition, when selecting the most reasonable thickness of steel sheet, its service time, quality and stiffness shall be considered, as well as the strength requirements of the plate under compression; pressure distribution, width, and specification of pressing plate.

If the thickness of the steel sheet is not enough, it is easy to bend, which will affect the production of the decorative sheets. If the thickness is too large and the steel sheet is too heavy, it will not only increase the cost of the steel sheet but also bring unnecessary difficulties to the operation. At the same time, the allowance for stainless steel sheet processing or use shall be considered.
