1、 Question raising

The commonly used detection method now is to dynamically detect powder through instruments, which takes up manpower, consumes time, and increases costs.

Based on these drawbacks, a quantitative guidance tool for mixing work is needed, which can predict the difficulty of powder mixing in advance and prepare to find the reasons for the difficulty of mixing. The alloy index is a tool for quantifying and qualitative mixing difficulty, causing mixing difficulties.

Mastering the calculation and usage methods of the alloy index can make complex and difficult testing work clearer and easier.

2、 The significance of the Jin He Index

1. Predict the difficulty level of mixed tasks in advance

Pre judgment: In the past, the mixing result was only known after the mixing was completed. By calculating the formula powder using the alloy index, the difficulty of mixing can be known in advance, accurate prediction can be made for the mixing task in advance, the reasons that affect uniform mixing can be found, the difficulty of mixing can be reduced, the success rate of mixing can be increased, and the smooth progress of the mixing task can be ensured.

2. Quantify and accurately analyze a certain powder that is difficult to mix and identify the reasons for it

By using the alloy index, powders with significant numerical differences can be accurately calculated, and the difficulty of mixing can be quantified. By manually intervening and preprocessing powders with excessively high or low alloy index, the difference in alloy index among powders is reduced, and the mean value between powders is brought closer, thus achieving the goal of uniform mixing smoothly.

3. Save a lot of experimental expenses such as material costs, labor, time, etc

Nowadays, staff usually check whether the mixing is qualified after it is completed. If it is not qualified, it needs to be remixed, and even directly invalidate this batch of powder, wasting money, labor, and energy.

With the Jin He Index, staff can know the difficulty level of mixed work, the reasons for the difficulties, and can save the cost of purchasing experimental instruments, save manual testing time, and reduce personnel participation.

4. The difficulty of powder mixing can be analyzed and judged by the alloy index to identify the cause

If encountering powder mixing tasks that are difficult to mix evenly, using the alloy index through detection and calculation can accurately identify the problem of mixing difficulties. With the identified problems, targeted solutions can be accurately proposed, and mixed difficulties can be easily solved.

3、 Example

The mixing of dialysate in the pharmaceutical industry and pigment in the additive industry, due to the large difference in particle size and good fluidity of the powder particles, results in insufficient holding power of the powder, which is prone to segregation and difficult to mix evenly.

The alloy index can be used to calculate the powders with significant numerical differences in advance. By preprocessing the powders that affect the mean, this numerical difference can be reduced, bringing the mean between powders closer, and achieving uniform mixing.

Using the alloy index to pre-treat materials to solve the mixing problem, but pre-treatment increases the process and also increases costs. The best approach is to use gravity diffusion and forced mixing equipment to complete high demand mixing tasks.

The Metal Index is the first tool that can systematically, data-driven, and accurately discuss mixing processes. Through the Metal Index, experimental steps can be reduced, the difficulty of mixing can be known in advance, and the reasons for the difficulty of mixing can be accurately determined. This elevates a mixing skill that has existed for hundreds of years to a technical level.

Ordinary workers who have mastered the alloy mixing index may defeat engineers who mix powder!
