氫氧化鈉化學式為NaOH，俗稱燒堿、燒堿、燒堿，是一種腐蝕性強的堿，一般呈片狀或塊狀，溶于水(溶于水溶液)，形成堿性溶液。它還能潮解，從空氣中吸收水蒸氣(潮解)和二氧化碳(變質)。
　　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, which is generally in flake or block shape, soluble in water (soluble in aqueous solution), forming an alkaline solution. It also deliquesces, absorbing water vapor (deliquescence) and carbon dioxide (metamorphism) from the air.
　　燒堿因其成本低而被廣泛用于豬場消毒，但你可能不知道的是，如果你不注意濃度，你的燒堿溶液可能沒有那么有效!
　　Caustic soda is widely used in pig farms because of its low cost, but what you may not know is that if you do not pay attention to the concentration, your caustic solution may not be as effective!
　　燒堿消毒錯誤:
　　Caustic soda disinfection error:
　　車輛消毒池加入氫氧化鈉量不足;汽車輪胎在未清潔的燒堿池中消毒;人員靴子不干凈，并與豬糞放在消毒盆上。
　　The amount of sodium hydroxide added to the vehicle disinfection tank is insufficient; the car tires are disinfected in the unclean caustic soda tank; the boots of the personnel are not clean and put on the disinfection basin with pig manure.

　　養(yǎng)豬場通常不計算所需的燒堿的量，也不稱燒堿的量。他們隨意添加苛性鈉。
　　Pig farms usually do not calculate the amount of caustic soda needed, nor is it called the amount of caustic soda. They add caustic soda at will.
　　正確操作:仔細計算消毒池中燒堿的量。例如，在6米*3米*0.2米深的燒堿罐中，必須添加多少燒堿才能達到2%的濃度?
　　Correct operation: carefully calculate the amount of caustic soda in the disinfection tank. For example, in a 6 m * 3 m * 0.2 m deep caustic soda tank, how much caustic soda must be added to achieve a 2% concentration?
　　水量:6×3×0.2=3.6m3, 3600kg×2%=72kg，只需加入燒堿72kg即可達到所需濃度的鐵鍬25 kg，不夠!
　　Water volume: 6 × 3 × 0.2 = 3.6m3, 3600kg × 2% = 72kg, just add 72kg caustic soda to reach the required concentration of 25 kg spade, not enough!
　　如果水箱是不規(guī)則的，每分鐘的水流可以乘以它被加入的時間來計算總水量，然后是需要的氫氧化鈉的量。
　　If the tank is irregular, the water flow per minute can be multiplied by the time it is added to calculate the total water volume, and then the amount of sodium hydroxide required.
　　它容易受到有機物的影響，泥在輪胎上，豬糞在靴子上都會影響消毒效果，清洗后放入消毒池中。
　　It is easy to be affected by organic matters. Mud on tires and pig manure on boots will affect the disinfection effect. After cleaning, it will be put into the disinfection pool.
