氢氧化钠化学式为NaOH，俗称烧碱、烧碱、烧碱，是一种腐蚀性强的碱，一般呈片状或块状，溶于水(溶于水溶液)，形成碱性溶液。它还能潮解，从空气中吸收水蒸气(潮解)和二氧化碳(变质)。
　　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.
　　烧碱因其成本低而被广泛用于猪场消毒，但你可能不知道的是，如果你不注意浓度，你的烧碱溶液可能没有那么有效!
　　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!
　　烧碱消毒错误:
　　Caustic soda disinfection error:
　　车辆消毒池加入氢氧化钠量不足;汽车轮胎在未清洁的烧碱池中消毒;人员靴子不干净，并与猪粪放在消毒盆上。
　　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.

　　养猪场通常不计算所需的烧碱的量，也不称烧碱的量。他们随意添加苛性钠。
　　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.
　　正确操作:仔细计算消毒池中烧碱的量。例如，在6米*3米*0.2米深的烧碱罐中，必须添加多少烧碱才能达到2%的浓度?
　　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，只需加入烧碱72kg即可达到所需浓度的铁锹25 kg，不够!
　　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!
　　如果水箱是不规则的，每分钟的水流可以乘以它被加入的时间来计算总水量，然后是需要的氢氧化钠的量。
　　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.
　　它容易受到有机物的影响，泥在轮胎上，猪粪在靴子上都会影响消毒效果，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.
