为预防和控制航天器、飞机、潜艇等密闭环境中的CO污染,以两种常用的非金属材料30-9304泡沫塑料、双面镀铝聚酯薄膜压敏胶带作为实验样品,密封于玻璃瓶中,在不同的温度条件下脱气,应用转化/气相色谱法在70d的时间内对脱出的CO量进行连续测试,并做曲线拟合与回归。结果表明:当脱气温度恒定时,脱气量与脱气时间的关系为“S”型曲线或指数曲线;当脱气时间恒定时,脱气量随温度升高呈指数增长;两种材料100℃脱气12h脱出CO的量相当于50℃脱气45d,材料的CO脱气存在等效原则。提示密闭条件下的非金属材料CO脱气有一定规律,探讨并利用这些规律有助于防止密闭环境CO的污染。
In order to prevent and control the CO pollution in confined environment such as spacecraft, aircraft and submarine, two commonly used non-metallic materials 30-9304 foam and double-sided aluminized polyester film pressure-sensitive adhesive tape were taken as experimental samples and sealed in glass bottles , Degassing under different temperature conditions, the application of conversion / gas chromatography in the 70d of the amount of prolapse of the continuous testing of the amount of CO, and make curve fitting and regression. The results show that when the degassing temperature is constant, the relationship between degassing quantity and degassing time is “S” curve or exponential curve. When the degassing time is constant, the degassing quantity increases exponentially with the increase of temperature. Degassing 12h out of the amount of CO is equivalent to degassing at 50 ℃ 45d, CO degassing material there is an equivalent principle. It is suggested that CO degassing of non-metallic materials under airtight conditions has certain rules. It is helpful to explore and utilize these rules to prevent CO pollution in airtight environment.
