Free alkali in Chinese alias

Chemical name of calcium hydroxide or calcium oxide

Cas15894-70-9

The product is made of chlorhexidine one step before calcium carbonate is mainly used for coating, rubber, plastics, paper. If the alkalinity of rubber is too high, it will affect the curing time and product quality of rubber. The high alkalinity in plastic will react with other plasticizers in plastic, cause the crispness of plastics and so on. The high alkalinity in paper will make it difficult to glue. Generally refers to the system of free (i.e., independent and complete by state or structure of the presence of an alkali) content of alkali, the general situation is: 1, first derivative, is the reaction of certain compounds, and compounds by detecting non reaction were calculated. 2, total alkalinity and pH detection, conversion. Titration is generally based on the molecular structure and properties, first of all make alkali titration calculating total alkali content, and then derived, then get the content of titration, then subtracting free alkali.
