| Description about the ozone |
| The ozone (OZONE ), molecular formula O 3, molecular weight 47. 9982 (?? 48), is the blue gas under the normal |
| atmospheric temperature, similar to the smell that the fish smell of fish. |
| The data of physics and chemistry about ozone are as follows: |
| Under the standard state, density 2. 144g/L. Because of the dry air close to the ground, the density is 1. 293g/L, so the
|
| density of ozone is 1 of the air. 658 times. |
| Here- 195. At the 40 C, liquid ozone density 1. 164g/ml. |
| The critical temperature is- 12. 10 C, critical pressure is 5. 45*10 6 handkerchieves. |
| The solubility in the cold water invites 10 times larger than the oxygen. |
| The air contains 0. About 02PPm of ozone. |
| Generally speaking, 1PPm ozone is desirable 2 in the air. 14mg/m 3, 1PPm ozone is 1mg/L in water. |
| Breathe for a long time> 0. 1PPm ozone, harmful to human body. |
| The density of ozone is in 0. At the 02PPm, sense of smell sharp one can feel , claim " feel the critical point "; 0. At the
|
| 15PPm, common people can smell, claim " sense of smell critical value" (order for sanitary standard also); 1-10PPm, in |
| order to " stimulate the range "; Above 10PPm, in order to be " poisonned in the range ". |
| The ozone is unstable, will resolve rapidly when high-temperature , will be divided into slowly the normal atmospheric |
| temperature (oxygen), at about 16 minutes in the half-life in 1% of the ozone aqueous solution, about 25 minutes in the half- |
| life in the air. |
| The unstability of the ozone makes it very difficult to realize storing bottledly, can only generally utilize on-the-spot production |
| of the ozone generator , produce and use at the same time at the same time. |
| The ozone is the oxidant better than the oxygen, and can oxidize under lower temperature . So, use everything of ozone ( |
| disinfecting, sterilization , aqueous cleaning, bleach, not make by oxidant,etc.) utilize their not to be the strong to oxidize by |
| ability in essence. Can know to have, the strong oxidizing of the ozone, normal atmospheric temperature function, especially |
| can reduce for the oxygen after it " works ", application its prolonged, mankind blue and green the three reasons of amidine. |
| The pure ozone will explode when struck , gritted but resolves , it is apt to explode when heated to include the high density |
| ozone solution, but only pay attention to avoiding, this kind of accident is not incident (as for ozone and poison to the human |
| body, ozone come out 150 over the past over years , have report that is poison to death in the same way yet). When the |
| ozone is used in the air and disinfect , should not have flammable and explosive gas of high density to disinfect live. |
| Ozone and water are the strong bleaching agent when stored together, its function is much faster than chlorine (Cl 2 ) , |
| hydrogen peroxide solution (H 2 O 2 ) , sulfur dioxide (SO 2 ). |
