The formulation design of electric butterfly valve directly affects the quality
The so-called formula design is based on the application performance requirements of electric butterfly valve products and the process conditions in the manufacturing process, through experiments, optimization, approval, reasonable selection of raw materials, and affirmation of the dosage and ratio relationship of various raw materials.

Section I Overview of Formula Design
1、 Contents of formula design
Formula design is a key link in the product consumption process. It has a decisive impact on product quality, processing performance and cost. The content of formula design shall include:
① Affirm the main performance indicators of the vulcanizate that meet the working performance requirements of the product and the range of these performance indicators;
② Affirm the process performance of the rubber compound necessary for the existing consumer equipment and manufacturing process and the range of these performance indicators;
③ Select the main materials and additives that can reach the specified properties of rubber compound and vulcanizate, and confirm their dosage and ratio relationship.
2、 Criteria for formula design
With the rapid development of science and technology, the process of modern formula design is no longer the simple experience of matching various raw materials, nor the "prescription and prescription" of Chinese ancestral traditional medicine. It is based on the full control of various coordination principles, the application of various basic theories of high molecular materials, the application of advanced technologies and theories of various related disciplines, Understand the relationship between the structure and performance of polymer materials, so as to give full play to the system effect of the whole formula system, and affirm the optimal dosage and proportion relationship of various raw materials.
It is impossible for any formula to optimize all the performances, but it is necessary to achieve the best comprehensive balance among the performance, cost and process feasibility of the product. With the least material consumption, the shortest time, and the smallest workload, through scientific formula experimental design methods, control the internal law of raw material matching, and design a suitable product formula.
