The embalming of the NANOMET ROOF SHEET continues twice a year

PVDF is polyvinylidene fluoride, which forms very stable fluorocarbon bonds due to the electronegativity of fluorine atoms, coupled with its unique molecular symmetry, making PVDF has extraordinary stability, unique resistance to ultraviolet photodegradation, and excellent insulation and mechanical properties. Since the application of fluorocarbon coated NANOMET ROOF SHEET, its pretreatment work has slowly developed towards simplicity and high performance.

Corrosion inhibitors are also commonly used when taking anti-corrosion measures against some NANOMET ROOF SHEET materials, but the anti-aging ability of corrosion inhibitors will disappear after a period of time. Therefore, its anti-corrosion work continues twice a year, at least once every two years. Moreover, if the waste water is not properly treated when it is treated with chemical anticorrosion, it will pollute the environment, so it is also necessary to pay great attention to the emission of chemical substances.

Due to the environmental impact of chemical methods, this method is now being gradually withdrawn from the pretreatment of NANOMET ROOF SHEET, and shot peening and blasting methods similar to the mechanical treatment of fluorocarbon coatings are now commonly used.
