Media resistance of natural rubber handwheel
2024-06-02
The natural rubber handwheel is a non-polar substance that is soluble in non-polar solvents and non-polar oils. Natural rubber handwheels are not resistant to solvents such as cyclohexane, gasoline, benzene, etc. Unvulcanized rubber can be dissolved in the above medium, and the vulcanized rubber hand wheel is swollen. The natural rubber hand wheel is insoluble in polar acetone and ethanol, and is more insoluble in water, resistant to 10% hydrofluoric acid, 20% hydrochloric acid, 30% sulfuric acid, 50% sodium hydroxide, and the like.
