摘要
Abstract
The safety of propellant mixing process was studied. Using the mixing process of the vertical mixer as an example, the torque variation was analyzed; the maximum torque peak appeared in the working procedure which solid material feeding had completed, it is also more dangerous process step. It was found that the relationship between torque and solid content is a quadratic function in the feeding process, with inflection point being solid content of 85 % , torque increased rapidly above this value; feeding mode of high solid formulations was proposed;the influences of vacuum process and cross-linking reaction in adhesive system before and after adding curing agent on the torque were verified;the torque and mixed amount were fitted into a cubic curve function and the relationship between torque and mixing speed is linear using empirical formula; the optimal mixing process was obtained to guide propellant production.关键词
