Because of the new coronavirus epidemic this year, many countries need to disinfect the space to prepay the virus. The demand for disinfection-related products increased suddenly this year, so we have been supporting our company's Spanish customers. They confirmed the order information to us in April. it need to purchase 1,000 sets of 3g ozone tubes for the assembly of space disinfection equipment.

We are also very grateful to our customers for their continuous support and affirmation, because the quality of the ozone tube is very stable, so there are follow-up orders. At the same time, we have been developing new products and constantly upgrading ozone tubes and power supplies. To meet customers' greater needs and stable performance.

Here we recommend that all customers should pay attention to the use of ozone tube

1. The "Industrial Hygiene Standards" formulated by the Ministry of Health of my country in 1979 stipulates that the ozone safety standard is 0.15 ppm.

2. The US standard stipulates that personnel can work for 8 hours at a concentration of 0.1 ppm. (Ozone concentration in general forest areas can reach 0.1ppm)

3. The International Ozone Association stipulates that professional indoor use of ozone is allowed to work for 10 hours at a concentration of 0.1 ppm.

4. The concentration of causing a certain reaction of the personnel is 0.5-1ppm, and the allowable contact time is 1.5 hours. If the time is long, you will feel dry mouth and other discomforts.

5. The concentration of 1-4ppm will cause people to cough, the allowable contact time is 1 hour.

6. The concentration of 4-10ppm will cause a strong cough, and the allowable contact time is 20 minutes.

7. The half-life of ozone is 20-50 minutes, and the final decomposition product is oxygen, so there will be no residual pollution to food.

At present, in the world, pure water and natural water (mountain spring water, mineral water, groundwater, etc. are made through filtration and other processes) are generally disinfected with ozone. In the application of tap water ozone purification, the international standard of 0.4mg/L solubility is maintained for 4 minutes, that is, the CT value is 1.6

The ozone concentration requirements of food processing workshops are relatively low, generally up to 2.5 ppm. For different food storage rooms, different ozone concentrations should be designed according to different stored substances. The ozone dosing method generally adopts the pipe type, and the open type can be used for small workshops

According to "Disinfection Technical Specification" and practical application experience,

300,000 purification grades take C = 2.5ppm = 5mg/m3;

For one hundred thousand purification grade, C = 5ppm = 10mg/m3;

For the purification grade, C = 15ppm = 30mg/m3;

Hundred-level C = 20ppm = 40mg/m3

Ozonegreenplant specializes in the production of ozone tube and complete ozone machines of different specifications. We always make our best efforts to meet the requirements of customers with our many years' experience, continuing research and technical innovation in Ozone industry.
