电热带为何会有防爆型?

发布于:2017-03-29 16:44来源:安邦电伴热带 作者:电伴热带厂家点击:

关于电热带防爆的类型的疑问,很多人都不了解在什么情况下具备能满足爆炸的条件,相反来说只要不满足这些条件就不会发生爆炸反应。通俗的来说爆炸是物质从一种状态,经过物理或化学变化,突然变成另一种状态,并放出巨大的能量,同时破坏性极强。爆炸急剧释放的能量,将使周围的介质遭受到高压化学反应或状态变化。

爆炸必须具备的三个条件:

1、氧气:空气;

2、爆炸性物质:能与氧气(空气)反应的物质,包括气体、液体和固体。气体:氢气,乙炔,甲烷等;液体:酒精,汽油;固体:粉尘,纤维粉尘等

3、点燃源:包括明火、电气火花、机械火花、静电火花、高温、化学反应、光能等。

易爆物质:很多生产场所都会产生某些可燃性物质。煤矿井下约有三分之二的场所有存在爆炸性物质;化学工业中,约有80%以上的生产车间区域存在爆炸性物质。氧气:空气中的氧气是无处不在的。点燃源:在生产过程中大量使用电气仪表,各种磨擦的电火花,机械磨损火花、静电火花、高温等不可避免,尤其当仪表、电气发生故障时。

客观上很多工业现场满足爆炸条件,当爆炸性物质与氧气的混合浓度处于爆炸极限范围内时,若存在爆炸源,将会发生爆炸。因此为了避免不必要的损失,在化工业管道、罐体等介质保温时采取防爆就很有必要了。本文地址:http://www.octaljam.com/js/jszc/938.html
