The development of wet-mixed materials used in sintering production has greatly improved production efficiency. With the popularity of sintering production, the requirement for wet-mixed materials is also increasingly demanding. In order to ensure the quality of wet-mixed materials and the accuracy of sintering production, it is necessary to conduct tests to analyze various elements / physical properties of wet-mixed materials. The water content of wet-mixed materials is very important in the use of wet-mixed materials and the accuracy of sintering production processes. In this report, the moisture content in wet-mixed materials used in sintering production will be discussed.
Water is an important component of wet-mixed materials used in sintering production and plays an important role in the production process. Water can affect the integrity of the material, and affect the adhesion and strength of the material. Too much water in the wet-mixed material will cause loose particles, and too little water will lead to poor particle cohesion, thus affecting the strength of the material. In addition, the presence of water in the material can also cause shrinkage and cracking after sintering. Therefore, to ensure the quality of sintering production, accurate measurement of water content in sintering production wet-mixed materials is essential.
Determination of moisture content in wet-mixed materials used in sintering production is mainly divided into two categories: volumetric method and gravimetric method.
The volumetric method is a method often used in sintering production, mainly including convective drying, drying at constant temperature and azeotropic distillation. In convective drying, the mixed material is dried in a vacuum drying oven, and the water present in the mixed material is evaporated by heating, and the height of the sample is measured in the vacuum drying oven. The water content of the mixed material can be obtained by measuring the height before and after drying. In drying at a constant temperature, the mixed material is placed in an environment at a certain temperature. By measuring the weight loss of the mixed material, the weight of water evaporated at the constant temperature can be calculated, and the water content of the mixed material is obtained by mass balance. The azeotropic distillation method is a method of separating water from the mixed material by changing the temperature.
The gravimetric method uses a drying oven or a balance to measure the weight change of the mixed material to calculate the water content. In this method, the mixed material is placed in a drying oven or a balance and heated or weighed, respectively, and the weight of the sample before and after drying is measured. Then, the weight reduction of the sample is calculated, and the water content in the mixed material is obtained through the mass balance equation.
In sum, the water content of wet-mixed materials used in sintering production is essential to the accuracy of sintering production processes. For the determination of moisture content in wet-mixed materials used in sintering production, volumetric method and gravimetric method are commonly used. Both methods have their own advantages and disadvantages, and the choice of which method should be based on the requirements of sintering production.
