The chemical formula of sodium hydroxide is NaOH, commonly known as caustic soda, caustic soda and caustic soda. It is a highly corrosive caustic soda, generally in flakes or blocks, which is easily soluble in water (soluble in water) to form an alkaline solution. In addition, it also has deliquescence and is easy to absorb water vapor (deliquescence) and carbon dioxide (deterioration) in the air.

燒堿由于低廉，被普遍應用于豬場，但你可能不知道的是，如果不注意濃度，你的苛性鈉溶液可能沒有效果！

Caustic soda is widely used in pig farm disinfection because of its low price, but what you may not know is that if you don't pay attention to the concentration, your caustic soda solution may not have disinfection effect!

燒堿誤區：

Misunderstanding of caustic soda disinfection:

添加到車輛池中的氫氧化鈉的量是不夠的；車輛輪胎在未經清洗的火堿池中；人員水靴未清洗干凈，并帶著豬糞踩在盆上。

The amount of sodium hydroxide added to the vehicle disinfection pool is not enough; Vehicle tires are disinfected in an unwashed caustic soda tank; The personnel's water boots were not cleaned and stepped on the disinfection basin with pig manure.

養豬場往往不計算所需燒堿的量，也不稱燒堿的重量，隨意添加例如，在車輛苛性鈉池中放5鍬苛性鈉（每鍬約5斤），這被認為是很高的，如果仔細計算，可能還不夠。

Pig farms often do not calculate the amount of caustic soda required or weigh the caustic soda and add it at will. For example, put 5 shovels of caustic soda (about 5 kg per shovel) in the vehicle disinfection caustic soda tank, which is considered to be very high. If calculated carefully, it may not be enough.

正確操作：要仔細計算池中的苛性鈉量例如：在6米*3米*0.2米深的燒堿池中，需要加入多少苛性鈉才能達到2%的濃度？

Correct operation: carefully calculate the amount of caustic soda in the disinfection tank. For example, how much caustic soda needs to be added to reach the concentration of 2% in a 6m * 3M * 0.2m deep caustic soda tank?

一水量：6×3×0.2=3.6m3，3600kg×2%=72kg，需加燒堿72kg達到要求濃度鐵鍬只有25斤，還不夠！

Primary water volume: 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!

如果槽不規則，則每分鐘的水流可以乘以加水時間來計算總水量，然后計算所需的氫氧化鈉量。

If the disinfection tank is irregular, the water flow per minute can be multiplied by the water addition time to calculate the total water volume, and then calculate the required amount of sodium hydroxide.

它很容易受到有機物的影響，輪胎沾泥，靴子沾豬糞會影響效果，清洗后才能進入池。

It is easily affected by organic matter. The disinfection effect will be affected if the tires are stained with mud and the boots are stained with pig dung. It can enter the disinfection tank only after cleaning.
