The invention relates to the field of emergency rescue, in particular to a portable rapid tester for the absorption rate of calcium hydroxide. The problems that an existing calcium hydroxide absorptivity testing method is long in testing time, complex in procedure, poor in accuracy and the like are solved. The calcium hydroxide absorptivity testing device comprises a pretreatment device used for polishing a testing sample, an absorptivity rapid detection system used for detection, a display and calibration module used for displaying data and a power supply module used for supplying power to the structure. The rapid absorption rate detection system comprises a sound wave exciter, a sample clamping and sound wave testing device, a low-noise signal line, a sound signal processor, a data converter and a displacement signal processor. According to the invention, the test time is extremely short, the test result precision can be controlled within 1%, the test and maintenance difficulty is low, and an operator can quickly operate. The method can be carried out indoors and can also be used for testing outdoors, and the requirements of the emergency rescue working environment can be completely met.
Description
technical field [0001] The invention relates to the field of emergency rescue, in particular to a portable quick measuring instrument for calcium hydroxide absorption rate. Background technique [0002] Positive pressure oxygen respirators are the necessary protective equipment for mine rescuers in the rescue process, and calcium hydroxide is the core protective barrier "absorbent" of positive pressure oxygen respirators. The quality of calcium hydroxide, whether it has deteriorated and the degree of deterioration is directly related to the life of the user. Therefore, a fast and effective calcium hydroxide absorption rate detection is very important for emergency rescue. [0003] Existing detection techniques for calcium hydroxide absorptivity include subjective inspection, weighing inspection, pH comparison, and laser infrared gas monitoring. Subjective inspection is carried out through visual organs and olfactory senses. This method is highly subjective and cannot be mea...
