V. Case Analysis
5.1 Case 1: Improvement of a pharmaceutical company’s hybrid equipment
A pharmaceutical company found during the production process that the agitator pads of the mixing equipment will wear and deform after being used for a period of time, resulting in a decrease in mixing efficiency. After analysis, it was found that the original stirring paddle material did not meet the medical grade standards and had poor wear resistance. The company decided to use polyurethane sponge softener to make new stirring paddles. After a period of trial, it was found that the mixing efficiency was significantly improved and the equipment operation was more stable.
5.2 Case 2: Upgrading of drying equipment of a pharmaceutical company
A pharmaceutical company found during the production process that the lining of the drying equipment will undergo chemical corrosion and wear after being used for a period of time, resulting in drug contamination. After analysis, it was found that the original lining material has poor chemical stability and its cleanliness does not meet the standards. The company decided to use polyurethane sponge softener to make new linings. After a period of trial, the drug was discoveredThe pollution problem has been effectively solved and the equipment operation has become more stable.
VI. Future development trends
