ActivePlastics—Determination of hexamethylenetetramine content in phenolic resins—Kjeldahl method,perchloric acid method and hydrochloric acid method
塑料 酚醛树脂中六次甲基四胺含量的测定 凯式定氮法、高氯酸法和盐酸法
Application Summary AI generated
This standard specifies three methods—Kjeldahl, perchloric acid, and hydrochloric acid—for determining the hexamethylenetetramine content in phenolic resins. It is applied in the quality control and testing of phenolic resin materials used in plastics manufacturing, particularly for ensuring proper curing agent levels in molding compounds, adhesives, and coatings. The standard is relevant for laboratories and production facilities in the rubber and plastics industry (ICS 83.080.10) that require accurate quantification of hexamethylenetetramine for process optimization and product compliance.
