2. purify air
After Hours, to inherent present embodiment 2 products obtained therefroms (the about 8g/m that sprays of a certain office
3) before and after, its airborne total number of bacteria detects relatively, presses standard No.: the bump method of GB/T 18883-2002 " IAQ standard " appendix E detects.Table 1
| Before the sprinkling | After the sprinkling |
Total number of bacteria cfu/m
3 | 3200 | 800 |
The total number of bacteria standard value of IAQ standard is 2500cfu/m
3, after product of the present invention sprayed, total number of bacteria reduced in the product, and air quality is improved.
3. device sterilization (keyboard, mouse)
Keyboard and mouse to 5 computers in the office are spraying embodiment 3 products (about 5g/m
2) before and after germ contamination detect contrast.Adopt the cotton swab method, sampling respectively, and carry out bacterial culture, colony counting and bacterial type and identify.
