酚醛塑料的再生利用

Recycling of Phenolic Plastics

酚醛塑料是一种网状立体交联的分子,具有良好的耐酸性能、力学性能,硬度大,阻燃性、电绝缘性好,耐热、耐溶剂,抗蠕变等优点,应用在电器、建筑材料、密封元件、餐具等。介绍了废酚醛塑料常用再生方法,并对现存的问题和发展前景进行分析。

Phenolic plastics is a three-dimensional mesh of insoluble cross-linked molecules, with rigidity, hardness, flame retardant, electrical insulation, heat resistance, solvent resistance, creep resistance, and many other advantages, and it has been used in electric apparatus, building materials, sealing ele- ments, tableware, etc. The recycling methods for commonly used waste phenolic plastics are presented, and the existing problems and developing prospect are discussed.
