The chemical formula of sodium hydroxide is NaOH, commonly known as caustic soda, caustic soda and caustic soda. It is a kind of caustic soda with strong corrosiveness. It is generally flaky or massive, and is easily soluble in water (soluble in water) to form alkaline solution. In addition, it also has deliquescence, easy to absorb water vapor (deliquescence) and carbon dioxide (deterioration) in the air.
Caustic soda is widely used in pig farm disinfection because of its low price, but what you may not know is that if you do not pay attention to the concentration, your caustic soda solution may not have disinfection effect!
Misunderstanding of caustic soda disinfection:
The amount of sodium hydroxide added to the vehicle disinfection pool is not enough; Vehicle tires are disinfected in an unwashed caustic soda pool; The staff did not clean their water boots and stepped on the disinfection basin with pig manure.
Pig farms often do not calculate the amount of caustic soda required, nor weigh the weight of caustic soda, and add it at will. For example, five shovels of caustic soda (about 5 jin per shovel) are put in the caustic soda pool for vehicle disinfection, which is considered to be very high, and may not be enough if calculated carefully.
Correct operation: it is necessary to carefully calculate the amount of caustic soda in the disinfection pool. For example, in the 6 m * 3 m * 0.2 m deep caustic soda pool, how much caustic soda needs to be added to reach 2% concentration?
One water quantity: 6 × three × 0.2=3.6m3，3600kg × 2%=72kg, it is necessary to add caustic soda 72kg to meet the required concentration. The shovel is only 25 Jin, not enough!
If the disinfection tank is irregular, the water flow per minute can be multiplied by the water adding time to calculate the total amount of water, and then calculate the amount of sodium hydroxide required.
It is very easy to be affected by organic matter. If the tires are stained with mud and the boots are stained with pig manure, the disinfection effect will be affected. Only after cleaning can it enter the disinfection pool.
