自燃温度 Autoignition temperature(重定向自Kindling point)
自燃温度(英语:autoignition temperature)或自燃点(英语:kindling point)指的是常压下,没有外部火花、火焰等火源点燃时,可燃物自燃的最低温度。在日常生活中所看到的自燃,原因大部分都是自燃点太低所造成。例如白磷的自燃点只是34℃,只要稍微加热一点,便会自燃,故通常都保存于水中。 自燃温度这一温度是用于克服该物质发生燃烧的活化能。当环境中氧气含量较高时,该化学物质的燃烧温度将降低。通常用自燃温度衡量某种燃料的混合物。液态化学物质的自燃温度采用下述方法测量:将可燃液体放入500毫升烧瓶中,将烧瓶置于恒温炉中,按照ASTM E659进行测量。当测量塑料的自燃温度时,可以在较大的压力和100%氧气环境中测量自燃温度。

Autoignition temperature 自燃温度(重定向自Kindling point)
The autoignition temperature or kindling point of a substance is the lowest temperature at which it will spontaneously ignite in normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion. The temperature at which a chemical will ignite decreases as the pressure or oxygen concentration increases. It is usually applied to a combustible fuel mixture. |
