(1) Sodium hydroxide: also known as caustic soda, caustic soda. White solid in the form of granules, flakes, rods or blocks. is a strong base, yes
Skin, fabric, paper, etc. are highly corrosive. Strong hygroscopicity, it is easy to absorb moisture and carbon dioxide in the air and gradually turn into sodium carbonate. It is easily soluble in water and strongly exothermic, and is widely used in papermaking, rayon, dyeing, soap, petroleum and other chemical industries.
  In this agent, it is used as the main component for removing grease. Choose industrial products.
(2) Trisodium phosphate: also known as sodium phosphate. Easily weathered in dry air. Heated to 100 ℃ to lose crystal water and become anhydrous. Soluble in water, almost all decomposed into disodium hydrogen phosphate and sodium hydroxide in aqueous solution, so the solution is strongly alkaline. Used as water softener, boiler cleaner, metal rust inhibitor, etc. The main ingredient for cleaning.
  This agent is used as a descaling agent. Choose industrial products.
(3) Triethanolamine: referred to as TEA, molecular formula N(CH2CH2OH)3. Colorless viscous liquid. Hygroscopic. When dew is placed in the air, the color gradually becomes darker. Can be mixed with water or alcohol, slightly soluble in benzene and ether. This agent has a sustained release effect. Choose industrial products.
(4) Sodium carbonate: also known as soda, soda ash, and sometimes soda ash.
  It is an important industrial alkali, with anhydrous, monohydrate, heptahydrate and decahydrate. Soluble in water, the aqueous solution is strongly alkaline. It is easy to absorb carbon dioxide in the air to generate sodium bicarbonate. Anhydrous sodium carbonate is white powder or fine particles. It is insoluble in alcohol and ether, and has a wide range of uses. It is an important raw material for glass, paper, detergent, soap and other industries. This agent is used as a detergent.
