Indice di prova e metodo di prova dell'olio di pino
L'olio di pino è un olio di resina naturale estratto dagli alberi di pino, chiamato anche retinolo. Ha una buona solubilità, viscosity and stability, and is often used in paint, Rivestimento, rubber and other fields. Inoltre, pine oil can also be used as a cleaning agent and disinfectant, eccetera.
Main performance
The main properties of pine oil are shown in the following table:
Prestazione | Index of detection |
---|---|
Exterior appearance | Colore, trasparenza |
Acid number | Mg KOH/g |
Grado di viscosità | millisecond |
Degree of solubility | Solubility in different solvents |
Densità di densità | G/ml |
These properties can be tested by different chemical analysis methods, physical tests and instrumental tests, Per esempio, acid values can be measured by acid-base titration, viscosity can be measured by viscometer, density can be measured by hydrometer, eccetera.

Metodo di rilevamento
Specific detection methods can be selected according to criteria, ad esempio:
Purezza: Gas cromatografia (GC) can be used to detect the content of various chemical components in pine oil, or infrared spectroscopy (IR) can be used to detect purity.
Relative density: can be measured using equipment such as a densitometer or a specific gravity bottle.
Indice di rifrazione: can be measured using a refractometer.
Flash point: can be measured using closed or open cup method.
Acid value: The acid value can be determined by titration.
Viscosità: can be measured using a viscometer.
Umidità: Halide titration, Coulomb method and other methods can be used to determine moisture content.
