　　片堿，即氫氧化鈉，歸屬于強堿性物質，具備溶解蛋白質的強腐蝕刺激性，可發揮消滅細菌病毒的功效，可與甲酚、植物油等搭配呈甲酚皂水溶液，用以手、設備等，也有環境、排泄物的處理。除此之外，也可與乙二胺四乙酸二鈉搭配，該水溶液可以用一根管清理劑，除可鰲合牙本質中的鈣，軟化根管內的牙本質壁、污漬外，也有一定的作用。適當濃度值的氫氧化鈉溶液，還可用以固定檢驗標本，也有調控藥物的PH值。

Sodium hydroxide, also known as sodium hydroxide, belongs to strong alkaline substances and has the strong corrosive and irritating properties of dissolving proteins. It can play a role in eliminating bacteria and viruses. It can be paired with cresol, vegetable oil, etc. to form cresol soap aqueous solution, used for disinfecting and sterilizing hands, equipment, etc., as well as for environmental and excreta treatment. In addition, it can also be paired with disodium ethylenediaminetetraacetic acid. This aqueous solution can be used as a root canal cleaner, which not only removes calcium from the occlusal dentin, softens the dentin wall inside the root canal, and removes stains, but also has a certain bactericidal effect. A sodium hydroxide solution with an appropriate concentration can also be used to fix test specimens and regulate the pH value of drugs.

　　除在臨床醫學上用途較普遍外，氫氧化鈉還是一種化工原料，可用以制作肥皂等物品。

In addition to being widely used in clinical medicine, sodium hydroxide is also a chemical raw material that can be used to make soap and other items.

　　在畜牧養殖這方面，可用以專門針對雞瘟等傳染性疾病進行工作。

In animal husbandry, it can be used specifically for disinfection and sterilization of infectious diseases such as chicken plague.

　　但其歸屬于強堿性，具備高腐蝕刺激性，無論是氫氧化鈉的固態物體還是水溶液，還是應該盡量避免直接接觸，以免對皮膚黏膜帶來過強的腐蝕和損害。若不慎進眼，需及早用大量的流動水清理，情況嚴重有可能會致使失明，如誤吞，有可能會帶來胃穿孔、消化道出血等病狀，因此應盡量避免直接接觸。

But it belongs to strong alkalinity and has high corrosive and irritating properties. Whether it is a solid object of sodium hydroxide or an aqueous solution, direct contact should be avoided as much as possible to avoid excessive corrosion and damage to the skin and mucous membranes. If accidentally entering the eyes, it is necessary to clean it with a large amount of flowing water as soon as possible. In severe cases, it may lead to blindness. If swallowed by mistake, it may cause symptoms such as gastric perforation and gastrointestinal bleeding. Therefore, direct contact should be avoided as much as possible.
