氢氧化钠的化学式为NaOH，俗称烧碱、烧碱、烧碱，是一种强腐蚀性的苛性碱，一般呈片状或块状，易溶于水（溶于水溶出），形成碱性溶液。此外，它还具有潮解性，容易吸收空气中的水蒸气（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 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.
烧碱由于价格低廉，被普遍应用于猪场消毒，但你可能不知道的是，如果不注意浓度，你的苛性钠溶液可能没有消毒效果！
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!
烧碱消毒误区：
Misunderstanding of caustic soda disinfection:

添加到车辆消毒池中的氢氧化钠的量是不够的；车辆轮胎在未经清洗的火碱池中消毒；人员水靴未清洗干净，并带着猪粪踩在消毒盆上。
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.
养猪场往往不计算所需烧碱的量，也不称烧碱的重量，随意添加例如，在车辆消毒苛性钠池中放5锹苛性钠（每锹约5斤），这被认为是很高的，如果仔细计算，可能还不够。
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.
正确操作：要仔细计算消毒池中的苛性钠量例如：在6米*3米*0.2米深的烧碱池中，需要加入多少苛性钠才能达到2%的浓度？
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，需加烧碱72kg达到要求浓度铁锹只有25斤，还不够！
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!
如果消毒槽不规则，则每分钟的水流可以乘以加水时间来计算总水量，然后计算所需的氢氧化钠量。
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.
它很容易受到有机物的影响，轮胎沾泥，靴子沾猪粪会影响消毒效果，清洗后才能进入消毒池。
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.
