片堿的主要成分氫氧化鈉的作用。氫氧化鈉(片堿的主要成分)又稱燒堿、苛性鈉等,在我們生活和生產中有著不一般的作用,用于制造紙漿、肥皂、染料、人造絲、制鋁、石油精制、棉織品整理,以及食品加工、木料加工等方面。氫氧化鈉在這么多方面都有著重要的作用,可見氫氧化鈉在我們生活和生產中的作用有多大。
The main component of flake alkali is sodium hydroxide. Sodium hydroxide (the main component of flake caustic soda), also known as caustic soda and caustic soda, plays an unusual role in our daily life and production. It is used to make pulp, soap, dye, rayon, aluminum, petroleum refining, cotton fabric finishing, food processing, wood processing, etc. Sodium hydroxide plays an important role in so many aspects. It can be seen that sodium hydroxide plays an important role in our life and production.
氫氧化鈉在化學實驗中的作用:除了能夠當做溶液試劑外,氫氧化鈉具有潮解性和吸水能力,是很好的堿性干燥劑。也可以吸收CO2等酸性氣體(實驗:S+O2=(點燃)SO2中,可利用這個特性,使用氫氧化鈉吸收SO2氣體)
Function of sodium hydroxide in chemical experiments: in addition to being used as solution reagent, sodium hydroxide has deliquescence and water absorption capacity, and is a good alkaline desiccant. It can also absorb acid gases such as CO2 (Experiment: in S + O2 = (ignition) SO2, sodium hydroxide can be used to absorb SO2 gas)
氫氧化鈉在造紙工業中的作用:氫氧化鈉在造紙工業中發揮著重要的作用。由于其堿性特質,它被用于煮和漂白紙頁的過程。
The role of sodium hydroxide in the paper industry: sodium hydroxide plays an important role in the paper industry. Because of its alkaline properties, it is used in the process of cooking and bleaching paper.
氫氧化鈉在水處理中的作用:氫氧化鈉被廣泛應用于水處理。在污水處理廠,氫氧化鈉可以通過中和反應減小水的硬度。在工業領域,是離子交換樹脂再生的再生劑。氫氧化鈉具有強堿性,且在水中具有相對高的可溶性。由于燒堿為液態,所以容易衡量用量,被方便的使用在水處理的各個領域。

Function of sodium hydroxide in water treatment: sodium hydroxide is widely used in water treatment. In wastewater treatment plant, sodium hydroxide can reduce the hardness of water by neutralization reaction. In the industrial field, it is the regeneration agent of ion exchange resin regeneration. Sodium hydroxide has strong alkalinity and relatively high solubility in water. Since caustic soda is liquid, it is easy to measure the amount of caustic soda and is convenient to use in various fields of water treatment.
氫氧化鈉被使用在水處理方面的如下課題:消除水的硬度;調節水的pH值;對廢水進行中和;離子交換樹脂的再生;通過沉淀消除水中重金屬離子。
Sodium hydroxide is used in the following topics of water treatment: eliminating the hardness of water; adjusting the pH value of water; neutralizing wastewater; regenerating ion exchange resin; eliminating heavy metal ions in water by precipitation.
洗滌用品
Washing supplies
肥皂:制造肥皂是燒堿更古老和更廣泛的用途,在制造肥皂的過程中,燒堿被用來中和脂肪酸。
Soap: making soap is the oldest and most extensive use of caustic soda. In the process of making soap, caustic soda is used to neutralize fatty acids.
洗滌劑:氫氧化鈉被用于生產各種洗滌劑,甚至如今的洗衣粉也是由大量的燒堿制造出來的,燒堿被用于硫化反應后對過剩的發煙硫酸進行中和。
Detergents: sodium hydroxide is used to produce various detergents, and even today's washing powder is made from a large amount of caustic soda, which is used to neutralize excess fuming sulfuric acid after vulcanization.
