As a chemical product, flake alkali has strong corrosiveness. What's the difference between flake alkali and sodium silicate? Next, let's take you to know something about it.

　　1、片碱在常温下是一种白色晶体，具有强腐蚀性，易溶于水，其水溶液呈强碱性，能使酚酞变红，性状是白色半透明片状固体，是根本化工质料。

　　1. Flake alkali is a kind of white crystal at room temperature. It is highly corrosive and soluble in water. Its aqueous solution is strongly alkaline, which can turn phenolphthalein red. It is a white translucent flake solid and is the basic chemical material.

　　2、片碱是固态氢氧化钠（NaOH）（结晶体）的商品名（你去买化学试剂，通常不说氢氧化钠，而是说片碱），氢氧化钠也俗称烧碱、火碱、苛性钠，因另一称号causticsoda而在香港称为哥士的。

　　2. Flake alkali is the trade name of solid sodium hydroxide (crystal) (you buy chemical reagent, usually not sodium hydroxide, but flake alkali). Sodium hydroxide is also commonly known as caustic soda, caustic soda and caustic soda. It is also known as Costa in Hong Kong because of its other name, causticsoda.

　　3、片碱广泛用于造纸、合成洗涤及番笕、粘胶纤维、人造丝及绵织品等轻纺工业方面，农药、染料、橡胶和化学工业方面、石油钻探，精粹石油油脂和提炼焦油的石油工业。

　　3. Flake alkali is widely used in papermaking, synthetic washing and light textile industries such as soap, viscose fiber, rayon and cotton products, pesticide, dye, rubber and chemical industries, oil drilling, refined petroleum oil and tar refining.

　　4、以及国防工业、机械工业、木材加工、冶金工业，医药工业及城市建设等方面。还用于制作化学品、纸张、番笕和洗涤剂、人造丝和玻璃纸，加工铝矾土制氧化铝，还用于纺织品的丝光处，水处理等。

　　4. As well as national defense industry, machinery industry, wood processing, metallurgy industry, pharmaceutical industry and urban construction. It is also used in the production of chemicals, paper, soap and detergent, rayon and cellophane, alumina from bauxite, mercerization of textiles, water treatment, etc.

　　片碱与硅酸钠的区别之处就是其应用行业的区别了，产品的本质不同所需要使用的行业也不大相同。虽然都属于化工物品，但在本质上还是有着一定的区别的。

　　The difference between flake alkali and sodium silicate is that their application industries are different, and the industries that need to be used for the different nature of products are not the same. Although they are all chemical products, they are different in nature.
