HH-PLOT molecular sieve 5Å GB 4396二氧化碳灭火剂分析毛细管柱

二氧化碳灭火器的筒身是耐压钢瓶，在钢瓶内装有液态二氧化碳，二氧化碳灭火器的钢瓶在20摄氏度时瓶内为60个大气座。二氧化碳灭火器有两种型式：一种是鸭嘴式开关的型式，另一种是轮式开关的型式。

二氧化碳灭火剂的主要作用是稀释空气中的氧浓度，使之达到燃烧的低需氧量以下，火即自动熄灭。

二氧化碳灭火剂是将二氧化碳以液态的形式加压充装于灭火器中，因液态二氧化碳易挥发成气体，挥发后体积将扩大760倍，当它从灭火器里喷出时，由于气化吸收热量的关系，立即变成十冰。此种霜状十冰喷向着火处，立即气化，而把燃烧处包围起来，起到隔绝和稀释氧的作用。当二氧化碳占空气的含量为30%〜35%时，燃烧就会停止，有很卨的灭火效率。


浩瀚色谱（山东）应用技术开发有限公司，采用HH-PLOT molecular sieve 5Å 毛细管柱测定二氧化碳灭火剂，面积归一法定量，结果准确。

GB 4396 Carbon dioxide fire extinguishing agent analysis capillary column Details:

Name: Capillary Column
Specification: 15m*0.53mm*50um
Model: HH-PLOT molecular sieve 5Å

The barrel of the carbon dioxide fire extinguisher is a pressure-resistant steel cylinder, which contains liquid carbon dioxide. The cylinder of the carbon dioxide fire extinguisher contains 60 atmospheric seats at 20 degrees Celsius. There are two types of carbon dioxide fire extinguishers: one is a duckbill switch type, and the other is a wheel switch type.

The main function of carbon dioxide fire extinguishing agent is to dilute the oxygen concentration in the air to make it below the minimum oxygen demand for combustion, and the fire is automatically extinguished.

Carbon dioxide fire extinguishing agent is to pressurize carbon dioxide into a fire extinguisher in liquid form. Because liquid carbon dioxide is easy to volatilize into a gas, the volume will expand 760 times after volatilization. When it is sprayed from the fire extinguisher, it will absorb heat due to vaporization. , Immediately became ten ice. This kind of frost-like ten ice sprays toward the fire place, immediately vaporizes, and surrounds the burning place, playing the role of isolating and diluting oxygen. When the content of carbon dioxide in the air is 30%~35%, the combustion will stop, and there is a great fire-extinguishing efficiency.


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses HH-PLOT molecular sieve 5Å capillary column to determine carbon dioxide fire extinguishing agent, and the area normalization method is used for quantification, and the result is accurate and reliable.
