This design also gives full consideration to the safety and environmental protection issues. In the production process, require that all personnel should obey strictly the regulation to operate, and usually attend the related training to know about the relevant information. In the environment protection part, wastewater and noise should be ejected with strict requirement.
According to the task issued by the design, the Expandable Polystyrene polymerization process section design is successful accomplished. Throughout the design process, I have a comprehensive understanding of production processes of Expandable Polystyrene and production application of Expandable Polystyrene. And according to the basis of expertise, combining my knowledge of the internship experience and flexible application, there is a certain foundation for me to engage in work related to production management for the future.
Under the teacher Xu Chunhua’s guiding, I have got many valuable suggestions to accomplish the design of the Expandable Polystyrene polymerization process section. Here, I express my sincere thanks to him.
As Expandable Polystyrene polymerization process section design of knowledge is broad, and my knowledge and experience are limited, cordially requesting teachers make a comment to the mistakes and the inadequacies of the design.
The knowledge of Expandable Polystyrene polymerization process section is so amplitude, and my knowledge and experience are limited, cordially requesting teachers make a comment to the mistakes and the inadequacies of the design.
