Indicele de testare și metoda de testare a uleiului de pin

Uleiul de pin este un ulei de rășină naturală extras din pini, numit și retinol. Are solubilitate bună, viscosity and stability, and is often used in paint, strat, rubber and other fields. în plus, pine oil can also be used as a cleaning agent and disinfectant, etc.

Main performance
The main properties of pine oil are shown in the following table:

PerformanţăIndex of detection
Exterior appearanceCuloare, transparenţă
Acid numberMg KOH/g
Degree of viscositymillisecond
Degree of solubilitySolubility in different solvents
Densitatea densitățiiG/ml

These properties can be tested by different chemical analysis methods, physical tests and instrumental tests, de exemplu, acid values can be measured by acid-base titration, viscosity can be measured by viscometer, density can be measured by hydrometer, etc.

Metoda de detectare
Specific detection methods can be selected according to criteria, ca:

Purity: Gas chromatography (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.

Refractive index: 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.

Viscozitate: can be measured using a viscometer.

Moisture: Halide titration, Coulomb method and other methods can be used to determine moisture content.
