Why PTFE conveyor's coating will have degradation

PTFE Conveyor Belt needs to contact with air, water, sunshineand materials for a long time during the usage, which easily leads to phenomenalike degradation and abscission of coating. Enterprises have emphasized on howto reduce the degradation of coating of conveyor in recent years.

The main reasons why Teflonconveyor is with degradation are that corrosion of water in air, tensilestrength, high working temperature and oxidation of air. Because water-solublematerials and water perssad in conveyor are easy to be extracted and dissolved,it is easy to be destroyed once there is too much water in air or conveyor issoaking in water.

The conveyorcontinues to rub the roller under repeated mechanical stress. This will heat updue to friction, and the higher the temperature is, the more it can increasethe rate of diffusion of oxygen and activation of the oxidation reaction rate,which induces oxidative chain reaction, forming force chemical process toaccelerate Teflon coating oxidation reaction rate so as to lead the conveyor`scoating aging off. The conveyor is exposed to air for a long time, and theoxygen in the air reacts with Teflon molecules, then the molecular chain isbroken or has extreme crosslinking. Consequently, it changes the property ofconveyor and makes it burn-in.

How toprevent the Ptfe Conveyor Belt from aging? When the conveyor runs, its largestrunning speed can not surpass1m/s.And if it conveys metal or large massive materials, try to use low-speedconveying or strengthen the set of carrying idler. The actual weight of thematerials transported should not exceed the rated load of conveyor. In order toprevent the conveyor from deflected running, the thread handling of capstan anddriven wheel as well as the surface of carrying idler should correspond to eachother. And if there occurs deflected running, handle with it in time.

Be sure touse carton boxes or thin films to package and seal when storing the conveyorsand the storing warehouse should also keep dry.
