Determination of Weight Gain Rate for Impregnated Graphite Products
Graphite products, especially those impregnated with fillers, are widely used due to their excellent mechanical and electrical properties. To fully utilize the potential of these products, it is important to understand the influence of the fillers. Therefore, the weight gain of impregnated graphite products needs to be determined.
In this paper, the method used to determine the weight gain rate of impregnated graphite products is described. The process is generally divided into four stages: pre-treatment, filling, curing, and weighing.
In the pre-treatment stage, the graphite products are cleaned, dried, and purged. This ensures that any contaminants present on the surface do not interfere with the uniformity of the final product. Next, the selected filler(s) are dispersed into a lubricant and mixed before being poured into the graphite product. This stage is to ensure that the filler(s) and the lubricant are evenly distributed throughout the product.
In the third stage, the filled graphite product is placed into a furnace for curing. The curing temperature, time, and type of lubricant used depend on the properties of the filling material. After the curing process is complete, the graphite product is taken out of the furnace and allowed to cool down.
In the final stage, the graphite product is weighed to determine the weight gain rate. This is done by comparing the weight of the filled graphite product to the weight of the graphite product before the filling process. The weight gain rate is calculated by dividing the weight of the filled graphite product by the weight of the unfilled graphite product before the filling process.
The weight gain rate is an important parameter used in assessing the performance and quality of impregnated graphite products. By accurately determining the weight gain rate, it is possible to ensure that the products meet the required performance and quality standards.
In conclusion, the weight gain rate of impregnated graphite products can be accurately determined using the process described above. This will help ensure that the products have the desired properties and performance, as specified by the customer or end-user.
