Technical Field

The invention belongs to the technical field of test equipment, and relates to a device necessary for detecting ozone gas generated in an ozone aging test chamber in a test.

Background

Ozone is widely recognized as a broad-spectrum high-efficiency bactericide because of the characteristic of extremely strong oxidizability. Ozone is called as green environmental protection element because in the process of sterilization and disinfection, the ozone can be automatically reduced into oxygen and water without any residue and secondary pollution, which can not be realized by any other chemical element disinfectants. Lightning strikes convert oxygen in the air to ozone, which is why the air is particularly fresh after a thunderstorm. Hospitals also use ozone with a certain concentration for disinfection, so we can also use the ozone in hospitalsThe odor of ozone can be smelled frequently. The concentration unit of ozone in the air is pphm, ppm or mg/m³Wherein 1ppm 100pphm 2.144mg/m³. Ozone is known to be effective in blocking ultraviolet light, but at the same time too high a concentration of ozone is harmful to humans, both to the benefit of and to the detriment of ozone in view of its properties. The domestic regulation is in the living environment, the ozone concentration exceeds 0.16mg/m³It constitutes a pollution; in the working place, the ozone concentration exceeds 0.2 mg/m³It constitutes a pollution. The safety standard of ozone is 0.15ppm, which is specified in the industrial hygiene standard established in 1979 by the ministry of health of China. The U.S. standard specifies that personnel can work at a concentration of 0.1ppm for 8 hours. (generally, the concentration of ozone in forest regions can reach 0.1ppm) the International ozone Association stipulates that a professional room using ozone is allowed to work for 10 hours at a concentration of 0.1 ppm. The concentration causing a certain reaction of a person is 0.5-1 ppm, the contact time is allowed to be 1.5 hours, and the person feels discomfort such as dry mouth after a long time. Concentrations of 1-4 ppm can cause coughing of persons and allow contact times of 1 hour. Concentrations of 4-10 ppm cause intense coughing, allowing contact times of 20 minutes. The half-life of the ozone is 20-50 minutes, and the final decomposition product is oxygen, so that no residual pollution is caused to the food. Practice proves that no damage to equipment and device materials is found after ozone sterilization and mildew prevention are applied for years.

The ozone aging test box is a method which can generate ozone gas, controls the specified concentration, is used for testing the ozone aging resistance of rubber and rubber products, has little ozone content in the atmosphere but is a main factor of cracking of the rubber, simulates and strengthens the ozone condition in the atmosphere, researches the action rule of the ozone on the rubber, rapidly identifies and evaluates the ozone aging resistance and the antiozonant protection performance of the rubber, and further adopts effective anti-aging measures to prolong the service life of the rubber products. Ozone aging test case can produce ozone gas to still should possess the concentration of control regulation, generally use ozone concentration detector to come real-time supervision and effective control ozone's concentration, the temperature in the test box body is 40 degrees centigrade, and relative humidity is 60%, and ozone concentration is 50pphm, 100pphm, 200pphm, 500pphm or higher concentration etc..

Ozone concentration is monitored by extracting ozonized gas from a test box and passing through an ozone concentration detector, an obtained numerical value signal is fed back to a touch screen instrument in time, and an instruction is sent out after the numerical value signal is analyzed by the instrument to control the output power of an ozone generator, so that the requirement of controlling and stabilizing the ozone concentration in the test box is finally met. In the test process, the ozone-containing gas extracted from the test chamber contains water vapor, and the more the water vapor is gathered, the interference on the ozone detector is caused, the reading of normal data is influenced, and the concentration detection distortion is caused. Therefore, the water vapor contained in the ozonized gas must be filtered in the test process to ensure the normal test. It is also known that high temperature makes ozone molecules more active, and ozone is gradually decomposed back and forth in a high temperature environment, so that a method of evaporating water vapor at high temperature is not preferable. The chemical drying agent can consume ozone gas, so that the water vapor contained in the ozonized gas is changed into condensed water to fall through a refrigeration method, the ozonized gas reaching the ozone detector is dry, and the ozone concentration is accurately detected and controlled by the ozone aging test box.
