天津塑料十二厂和天津塑料研究所承担的“六五”国家科技攻关项目—PVC 塑料内门(整体型)最近通过了部级技术鉴定。该项目从型材的配方设计、工艺条件优选,塑料内门结构、型材及塑料整体内门性能测试和标准制订、以及塑料内门的推广应用等方面进行了大量研究工作。并参考了已生产的两代塑料内门的结构造型,设计出15种型材断面结构,能装配成住宅系列门(居室内门、厨房门、厕所门)以及公共建筑中的办公室门等。还制定了企业标准、施工的
The “Sixth Five-Year” national science and technology research project undertaken by the Tianjin No. 12 Plastics Factory and the Tianjin Institute of Plastics—the PVC plastic inner door (integral type) has recently passed the ministerial-level technical appraisal. The project has carried out a lot of research work from the formulation design of the profiles, the optimization of the process conditions, the performance testing and standard formulation of the plastic inner door structure, the profile and the plastic inner door, and the popularization and application of the plastic inner door. With reference to the structural modelling of the two generations of plastic inner doors that have been produced, 15 profile section structures have been designed, which can be assembled into residential series doors (interior doors, kitchen doors, toilet doors) and office doors in public buildings. Also established corporate standards, construction
