Can the sodium hypochlorite spray gun adjust the concentration to meet different disinfection needs?

Sodium hypochlorite spray guns can meet different disinfection needs by adjusting the concentration of the disinfectant used. However, the adjustment is based on the concentration of sodium hypochlorite solution sprayed into the spray gun, rather than directly adjusting the concentration of the spray gun itself. The following is a point by point introduction:

1. Adapt to the disinfection needs of different scenarios
Explanation: Different usage scenarios have different requirements for disinfection intensity, and the required concentration of sodium hypochlorite solution also varies.
Daily cleaning: 200-500mg/L
Public areas: 500-1000mg/L
Epidemic or high-risk locations: 1000-2000mg/L
Advantages: Suitable concentrations can be formulated according to actual needs, improving efficiency and saving resources.

2. Adjust the concentration by pre configuring the solution
Explanation: The spray gun itself usually does not automatically change the concentration, but relies on the user to prepare sodium hypochlorite solutions of different concentrations.
Suggestion: Before use, dilute the original solution (such as household 84 disinfectant) with pure water to the desired concentration according to environmental requirements, and then pour it into the spray gun.

3. Adapt to disinfecting different surfaces or objects
Explain:
Ground and walls: High concentration solution (1000mg/L) can be used
Surface of the item, door handle: can use medium concentration (500mg/L)
Children's toys or areas with frequent contact: It is recommended to use low concentrations (200-300mg/L) and wipe them clean afterwards.

4. Avoid unnecessary corrosion or irritation
Explanation: Excessive concentration may cause metal corrosion, plastic aging, or irritation to the human body.
Suggestion: Adjusting the concentration is not only for disinfection effectiveness, but also for balancing material safety and personnel health.

5. Some spray guns have flow/spray volume adjustment functions
Note: Although the spray gun does not directly adjust the "concentration", some models can adjust the spray amount and spray fineness, thus affecting the "effective dose" per unit area.
Benefits: suitable for small range mild spray or large range strong coverage, improving the flexibility of use.

6. Follow the disinfectant instructions for proportioning
Explanation: The concentration adjustment should strictly follow the instructions of sodium hypochlorite products to avoid ineffective concentration and harmful concentration.
Suggestion: If using household 84 disinfectant (effective chlorine about 5%), the common ratio is:
Daily disinfection: 1:100 (i.e. 10ml mixed with 1L of water, approximately 500mg/L)
Key area: 1:50 (i.e. 20ml mixed with 1L of water, approximately 1000mg/L)
