BAIJIAN - Third party testing organization
At present、 the application field of plastic materials is still further expanding、 involving various aspects of the national economy and people's lives. To engage in plastic molding and processing、 one must be familiar with the structure、 performance、 and application of plastic materials、 and understand the development status of plastic materials. This textbook is written based on this starting point. Through the study of this textbook、 students can become familiar with the structure and performance of plastic materials、 and achieve the following goals: ① Familiarize themselves with the structure、 performance、 and application range of commonly used plastic materials. ② Able to identify commonly used plastic materials based on their appearance and combustion characteristics Familiar with the working principle、 commonly used varieties、 and application range of commonly used plastic additives、 and able to conduct basic performance tests. ④ Able to select appropriate material varieties and models based on processing methods and product performance requirements、 and be able to design commonly used formulas. In addition to the above points、 attention should also be paid to integrating theory with practice、 paying more attention to observing daily necessities、 distinguishing the characteristics of plastic materials used in various products、 and comparing and analyzing the similarities and differences between materials to better grasp the characteristics of materials、 laying a solid foundation for engaging in plastic processing. Due to the rapid development of modification technology for plastic materials、 it is also necessary to understand new materials and processes to make their own contributions to the development of the plastic industry
