Application introduction and analysis of flake sodium hydroxide
When it comes to flaky sodium hydroxide, many people will say that I am confused. In fact, we all have a better understanding of this chemical substance, which is usually called caustic soda and sodium hydroxide. This material is very corrosive. Whether it is detected in powder or solution on the skin, it will cause great damage and burn the skin. Therefore, this substance should be handled with care.
After understanding its related chemical properties, we will introduce its functions. It can refine oil. After the petroleum products are washed with sulfuric acid and other substances, some acidic substances often remain, so they need to be washed with sodium hydroxide solution. After repeated washing with water, refined products can be obtained.
Secondly, flaky sodium hydroxide has also been widely used in my country's clothing industry. After the solution of this substance is used in the treatment of cotton and linen fabrics, the fiber properties are changed. Mainly man-made fibers, this material will be used in the production process.
Of course, the well-known industry of papermaking also uses this chemical. We know that grass or wood will be the raw material for papermaking. These raw materials not only contain non-cellulosic materials such as gums, but also cellulosic materials. This material can remove lignin from the wood until it is separated from the cellulose, thereby obtaining pulp.
1. When sodium hydroxide is opened, it will absorb water vapor (moisture absorption) from the air. Sodium hydroxide dissolves like ethanol or glycerin. Spanish globulin is a highly corrosive alkaline substance. After being dissolved in water, the phenolphthalein test paper will be red, and the litmus test paper will be blue.
2. There are two types of caustic soda: solid caustic soda is white, block, flake, rod, granular, and fragile; pure liquid caustic soda is colorless and transparent. Sodium hydroxide is also soluble in ethanol and glycerin; but insoluble in ether, acetone and liquid ammonia. Sodium hydroxide, also known as alkali or caustic soda, has the general formula of sodium hydroxide and is a highly corrosive metal matrix. Flaky sodium hydroxide is a white solid that can be in the form of granules, flakes or granules, although it is sometimes in the form of a 50% saturated solution.
