How to remedy plastic deformation?
The shape of the original space cannot be restored. The gas is not the same, because the free change of gas molecular positions, the intermolecular distance and temperature pressure and other factors. While the space is limited to the shape of gas container to accommodate it. As long as the shape of the container can be restored, but the properties of gases are full recovery. And the properties of a solid but small changes in the local and not fully recovered, so we can find x0d, often heated or refrigerated plastic box, in the year after use, will become worse than the original so neat. Its deformation makes it no longer that tight sealing.
This is a bar of iron, but iron bar has also been beating can recover the original straight, but shaped object is more difficult. Speak understand the truth, more trouble, but we can understand in this way, objects when temperature changes, the distance between the molecules is changed, then the temperature recovery after the distance between the molecules can also restore the original value, but the spatial arrangement of molecules is different,
Quality solutionsIn general family conditions, basically impossible to recover the original shape. Because the plastic in the thermal deformation, because after cooling contraction may not according to the original look, we know that the sheet metal after heating cooling becomes uneven, you repeat heating and cooling, it is impossible change back to the original flat state.
