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.

烧碱由于低廉，被普遍应用于猪场，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!

烧碱误区：

Misunderstanding of caustic soda disinfection:

添加到车辆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；人员水靴未清洗干净，并带着猪粪踩在盆上。

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.

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, 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.

正确操作：要仔细计算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: 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，需加烧碱72kg达到要求浓度铁锹只有25斤，还不够！

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

它很容易受到有机物的影响，轮胎沾泥，靴子沾猪粪会影响效果，清洗后才能进入池。

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.
