【摘要】 目前化学实验室排风设备生产厂家较多,产品的规格型号数十种以上,产品在大中院校和科研单位普及速度很快.由于此类设备是由多个单元设备和材料组合而成,因此,它的性能及技术标准涉及排风速度,排风量,排毒效果、噪声以及所用材料标准等多个方面.本文综合了相关国家标准,又提出了以"氨检法"现场检测该类设备的关键性技术标准,具有实际应用意义.更多还原

【Abstract】 There are many factories to produce ventilation equipment for the chemistry lab. And there exist more than 10 kinds of ventilation equipment. The chemistry lab ventilation equipment is more and more popular in universities and in institutes.The Ventilation arrangement is composed of several units.The qualities and technical standards of the equipment include the ventilation velocity,the ventilation capacity,the effect of ejecting ,the noise,and the material standard,etc.In this paper the ventilation equipment technical standards of several countries were studied and the ammonia detection was proposed to examine the key qualities of the ventilation arrangement.更多还原
