Product Details
The overall structure of the aerosol chamber mainly consists of the chamber body, temperature and humidity control system, air mixing fan system, lighting system, exhaust system (including air valve), ultraviolet disinfection, transmission window, air inlet system (including air valve), sampling and filling port, and pollution source generation device.
Group 2: spray in an aerosol chamber of 20m '~30m' according to the amount of disinfectant required in the instructions. spray is completed
After the scheduled disinfection time, immediately use a six stage air sieve impact sampler containing a neutralizer nutrient agar plate to sample (the air sampling volume is the same as the pre-set disinfection sample volume for air disinfection identification test), and after 10 minutes of action, draw 0.1ml of each sample. Apply the bacterial suspension used in the experiment to six disinfected plates, and perform live bacterial culture counting (calculate the average number of bacterial colonies on the six plates).
Result determination
4.1. Group 1.2.3 has a similar amount of test bacteria growth, and the results should be between 50 CFU/plate and 300 CFU/plate. The error rate of colony count between groups should not exceed 15%. The formula for calculating the error rate of colony count between groups 1, 2, and 3 is as follows:
The error rate of inter group colony count=the sum of absolute values of the average number of colonies between three groups and the average number of colonies in each group, X100%
1、 Selection of metal corrosion test methods
1.1 Corresponding metals or alloys should be selected for corrosion testing based on the objects and environment disinfected by disinfectants or disinfection equipment. If there is no specific usage object, commonly used carbon steel, aluminum, copper, and stainless steel materials should be tested.
1.2 Choose the corresponding metal corrosion test method based on different chemical disinfection methods, as shown in Table 1
Setting of test environment conditions:
Turn on the temperature and humidity adjustment device, and simultaneously adjust the temperature and relative humidity of the two aerosol chambers to the required temperature (20 ° C~25 ° C) and relative humidity (50%~70%) for the test.
3. Aerosol spray contamination:
In the control group and test group aerosol chambers, spray bacteria according to the set pressure, gas flow and spraying time of different aerosol spray. Use a fan (agitator) to mix while spray to stain bacteria. When the spray is finished, continue to stir for 5 min and keep still for 5 min.
