(1)Observe with your eyes: FalseSilicone oil It will be relatively turbid, with a strong smell and a bad smell;
(2) Use fire To test: use a glass rod or iron rod dipped in a small amount of silicone oil to ignite, it can ignite andWhat emits black smoke is white mineral oil , because white mineral oil is a petrochemical product. Pure silicone oil will not burn when ignited by fire, and is odorless, clear and transparent, non-toxic. The ignition point of silicone oil is 320 degrees, and the ignition point of white mineral oil is 100 degrees.
(3) Freezing pointTest method: Use 100 grams each of pure silicone oil and white mineral oil, put them in the refrigerator at the same time, and adjust to -5 -10 degrees, after two hours of experiment, the fake silicone oil will appear turbid or frozen, while the real silicone oil is clear and transparent, and will not freeze even at -50 degrees.
