兵器工业部十二月八日在长春召开了“PSM 光学塑料技术鉴定会”。这种光学塑料是以甲基丙烯酸甲酯和苯乙烯为主体制成的。它具有较高的光学折射率、较低的阿贝数,以及较好的透过率;具有较低的密度,较高的硬度,耐磨性及韧性。这种材料合成工艺简单,易于控制,原料易得,成本较低。
Weaponry Industry Department held “PSM Optical Plastic Technical Appraisal Meeting” in Changchun on December 8. This optical plastic is made of methyl methacrylate and styrene as the main body. It has a higher optical refractive index, lower Abbe number, and better transmittance; with lower density, higher hardness, wear resistance and toughness. This material synthesis process is simple, easy to control, raw materials easily available, low cost.
