摘要
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。
The inorganic crystal material KBr and teflon as organic protective material is used as 15-38μm,15-60μm wide-waveband extra-far infrared window material by thermal synthesis technology.The sample size is Φ20mm×3-5mm.The result of anti-corrodent indicated that the material can endure strong acid,strong alkali and part of organic solvent.The material can be used under 115 centigrade according to the mechanical intensation analysis.The result of infrared transimissivity test indicates that its transimissivity is above 50% in 15-38μm and 15-60μm waveband and below 15% in 1-15μm waveband.The influence factor of material transmittance is analysized.
