提到片堿，大家可能不太清楚是什么，但是提到燒堿，大家就明白了。片堿就是片狀的固態氫氧化鈉；同樣，液堿也就是液態氫氧化鈉。氫氧化鈉是一種化工原料，在廢水處理、堿性氧化、除銹等各種方面都有良好的應用。

When it comes to caustic soda, you may not be quite sure what it is, but when it comes to caustic soda, you understand. The flake alkali is the flake solid sodium hydroxide; Similarly, liquid caustic soda is also liquid sodium hydroxide. Sodium hydroxide is a chemical raw material, which has good applications in wastewater treatment, alkaline oxidation, rust removal and other aspects.

片堿、粒堿、固堿化學名“氫氧化鈉”，俗稱燒堿、火堿、苛性鈉。為無機化合物，化學式NaOH，具有強腐蝕性，易溶于水，其水溶液呈強堿性，能使酚酞變紅。氫氧化鈉是一種常用的堿，是化學實驗室的必備藥品之一。它的溶液可以用作洗滌液。

The chemical name of flake caustic soda, granular caustic soda and solid caustic soda is "sodium hydroxide", commonly known as caustic soda, caustic soda and caustic soda. It is a Inorganic compound with chemical formula NaOH, which is highly corrosive and easily soluble in water. Its aqueous solution is strongly alkaline and can make phenolphthalein red. Sodium hydroxide is a commonly used alkali and one of the essential drugs in chemical laboratories. Its solution can be used as a washing solution.

片堿和液堿的主要成分都是氫氧化鈉，區別在于一個是固態，一個是液態。液堿和片堿本身對混凝反應沒有影響，混凝反應主要控制：PH值、溫度、藥劑擴散和保護絮體增大的水利條件，無機、有機混凝劑的選擇，投加量等，所以片堿和液堿的主要作用是調節PH。

The main component of flake caustic soda and liquid caustic soda is sodium hydroxide. The difference is that one is solid and the other is liquid. Liquid alkali and flake alkali themselves have no effect on the coagulation reaction. The coagulation reaction mainly controls: pH value, temperature, chemical diffusion, hydraulic conditions for protecting the increase of flocs, selection of inorganic and organic coagulants, dosage, etc. Therefore, the main function of flake alkali and liquid alkali is to regulate the PH.

相同點

Similarities

1、生產所用原材料相同。

1. The raw materials used for production are the same.

2、分子式相同，都是NaOH，是同一種物質。

2. The Molecular formula is the same, both are NaOH, which is the same substance.

3、都具有強烈的腐蝕性，能迅速灼傷皮膚，遇水溶解。

3. Both have strong corrosiveness and can quickly burn the skin, dissolving in water.

不同點

Differences

1．生產過程中所用的設備不同，片堿是由片堿機刮片后，經過冷卻裝入袋中；粒堿是由噴漿造粒設備生產；固堿是直接利用輸送管道輸送到固堿桶中。

1. The equipment used in the production process is different. The flake alkali is scraped by a flake alkali machine and cooled into a bag; Granular alkali is produced by spray granulation equipment; Solid alkali is directly transported to a solid alkali drum through a transportation pipeline.

2．產品外部形態不同，片堿是片狀固體，粒堿是珠狀圓形固體，固堿是整體一塊。

2. The external form of the product is different, with flake alkali being a flake solid, granular alkali being a bead like circular solid, and solid alkali being a whole piece.

3．用途不同：片堿多用于化工、印染、污水處理、、農藥、電鍍等；粒堿主要用于醫藥、化妝品等化工行業，實驗室中用粒堿要比片堿方便的多。固堿多用于醫藥化工。

3. Different uses: flake alkali is commonly used in chemical engineering, printing and dyeing, sewage treatment, disinfection, pesticides, electroplating, etc; Granular alkali is mainly used in chemical industries such as pharmaceuticals and cosmetics, and it is much more convenient to use granular alkali in the laboratory than flake alkali. Solid alkali is often used in pharmaceutical and chemical industries.

具體選用哪個是根據水廠的使用需求來決定的，液堿反應速度比較快，投加簡單，不過要控制好溶度，否則低溫下容易結晶。片堿雖溶解麻煩，但存儲或搬運比較方便。

The specific choice depends on the usage needs of the water plant. The liquid alkali reaction speed is relatively fast and the addition is simple. However, it is necessary to control the solubility, otherwise it is easy to crystallize at low temperatures. Although the dissolution of caustic soda is troublesome, it is more convenient to store or transport.

需要注意的一點是，片堿和液堿都是在廢水處理中經常使用的，但是它們不能混合放置，需要分開。更多相關事項就來我們網站http://www.yiqijieneng.cn咨詢吧！
