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.

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 do not 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 pool; The staff did not clean their water boots 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, 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.

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: 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?

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！

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!

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 adding time to calculate the total amount of water, and then calculate the amount of sodium hydroxide required.

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 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.
