Concentration to be prepared × quantity to be prepared/original drug content = required original drug quantity, and preparation quantity-required original drug quantity = water addition. 84 Disinfectant is irritating and corrosive to some extent, and can only be used after dilution. Generally, the dilution concentration is1:500 and1:200, and the soaking time is 10 to 30 minutes.
84 disinfectant solution ratio of 1:500: add clean water: 1 kg, 5 kg,1kg, 20 kg. Corresponding to 84 disinfectant: 1ml, 5ml, 10ml, 20ml；; 84 disinfectant solution ratio of 1:200: add clean water: 1 kg, 5 kg,1kg, 20 kg. Corresponding to 84 disinfectant: 2.5ml, 12.5ml, 25ml, 50ml.
Basic components of 1 84 disinfectant:
The main components of disinfectant are sodium chloride and sodium hypochlorite. Among them, sodium chloride is to increase ion concentration, improve conductivity and promote electrolyte solubility; Sodium hypochlorite is the key component to achieve disinfection.
2. Proportional relation in the ratio formula:
The proportional relationship in the ratio formula is determined according to the solubility of sodium chloride and the activity of sodium hypochlorite. In general, the ratio of 84 disinfectant is1:5, that is, 84 grams of sodium chloride and 420 grams of sodium hypochlorite are added to each liter of water. This ratio can ensure the effective sterilization effect of disinfectant to a certain extent.
3. Adjustment of proportioning formula:
According to the specific needs, the ratio formula can also be adjusted appropriately. If it is necessary to improve the sterilization effect of disinfectant, the content of sodium hypochlorite can be increased and the content of sodium chloride can be reduced; If it is necessary to reduce the pungent taste of disinfectant, the content of sodium chloride can be appropriately increased and the content of sodium hypochlorite can be reduced.
4. Precautions:
Use purified water or filtered water to prepare disinfectant to ensure accurate ratio; In the preparation process, sodium chloride should be completely dissolved first, then sodium hypochlorite should be added and stirred evenly; When using disinfectant, you should abide by relevant safety operation procedures, such as wearing protective gloves and masks; Disinfectant is corrosive and irritating to some extent. Avoid direct contact with skin and eyes. If it is accidentally contacted, it should be washed immediately with clear water.
