PE wax has long nonpolar carbon chains with strong polarity. Its structure in the polarity and plastic compatible part of the internal lubrication, in the polarity and plastic incompatible part of the external lubrication and demoulding, so how to identify the true and false PE wax?
1, flake polyethylene wax real wax is plastic, hard feeling, the same as plastic sheet, smooth surface, translucent, natural white or yellowish, break the layer is not layered, no lime powder, black spots and other impurities, one side reflecting the light to see a good brightness;
2, hand to touch the real product has a good smoothness, feel the feeling of plastic rather than paraffin wax, hard, brittle, fragile, not lumped at room temperature. Fake products containing paraffin wax, hardening oil and fetol wax are greasy, oily and feel like candles, or rough, looking like no good flour, soft and powder will become a group if held by hand;
3. The smell of the real product smells of plastic, while the fake product smells of paraffin wax or strong peculiar smell;
4, boiling water put the wax plate in glass, add hot water and boil for 5 minutes, the shape of the wax plate is unchanged is genuine, paste or deformation is containing paraffin and other impurities. Although the test method is different, the test environment is different, but the softening point of the real product must be higher than 100 degrees Celsius.
5. The melting point of the real product is generally about 105 degrees, and the melting range is narrow. The melting point of other substances is low and the melting range is wide. Infrared spectrometers are like eyes, easy to tell the truth, but the equipment is more expensive. Mri is not to mention.
