在一定的温度、压力等条件下,采用有机材料(聚四氟乙烯)和无机晶体(KBr、CsI),通过热合技术研制出样品几何尺寸为Φ20mm×3-5mm、透射波段分别为15-38μm(PE-KBr)和15-60μm(PE-CsI)的透极远红外复合光学材料。抗腐蚀性能测试结果表明,材料耐强酸、强碱及部分有机溶剂。机械性能分析表明材料在小于115℃范围内可安全使用。极远红外透过率测试结果表明,在1-15μm波段,平均透过率小于15%,15-38μm和15-60μm极远红外波段,平均透过率大于50%,并对影响材料透过率的因素进行了分析。
Under certain conditions of temperature, pressure and other conditions, using the organic material (polytetrafluoroethylene) and inorganic crystals (KBr, CsI), through the heat sealing technology to develop a sample geometry Φ20mm × 3-5mm, transmission bands were 15-38μm (PE-KBr) and 15-60μm (PE-CsI) of the transmission of far-infrared composite optical material. Corrosion resistance test results show that the material resistant to acid, alkali and some organic solvents. Mechanical analysis shows that the material can be safely used in the range of less than 115 ℃. The far infrared transmittance test results show that in the 1-15μm band, the average transmittance of less than 15%, 15-38μm and 15-60μm far infrared band, the average transmittance greater than 50%, and the impact of material through The rate of the factors were analyzed.
