1. Performance and uses: Bactericide SM-404 is a compound quaternary ammonium salt bactericidal and algaecide. It has a good ability to kill bacteria, algae and slime in the circulating cooling water system. It has high efficiency, broad spectrum, low toxicity, It has the advantages of fast and long-lasting drug effect, strong penetrating power, convenient use, suitable temperature and wide PH range, etc., long-term use will not make bacteria and algae resistant.
2. Quality index
| Index name | Index |
| Appearance | Light yellow transparent liquid |
| Active matter content% ≥ | 30 |
| Ammonium salt content≤ | 2.0 |
| PH value ≤ (original solution) | 8.0 |
| Density (20 ℃) g/cm3 | 1.0±0.05 |
3. Usage adopts impact dosing, generally dosing once a week, the dosing amount is generally 80-100 mg/L, which means it has a killing effect on bacteria and algae. If there are more algae and slime, if you want to get a quick peeling effect, you can appropriately increase the dosage of 100~200mg/L, and remove the floating matter in time. When the foam is too large to affect the production, you can add defoamer S M-407.
