Description
Technical field
The present invention relates to vehicle glass field more particularly to a kind of glass multiposition pressure sensitive platforms.
Background technique
Glass is neither crystalline state, nor amorphous state, nor polycrystalline state, nor mixed state.Theoretical title is glass
State.Glassy state at normal temperature the characteristics of be: shortrange order, i.e., in several or dozens of atoms range, atomic ordered arrangement, be in
Existing crystal characteristic；Longrange disorder after being further added by atomic quantity, becomes as a kind of unordered ordered state, confusion degree class
It is similar to liquid.Macroscopically, glass is a kind of solid substance again.
Glass is exactly such a substance.The reason of causing this structure of glass is: the variation of the viscosity with temperature of glass
Speed is too fast, and crystallization rate is too slow.When the temperature drops, viscosity has just become very large at the beginning of crystallization just,
The movement of atom is locked, and causes this result.So glassy state is similar to solid liquid, the atom in substance is forever
During being far at crystallization.
Therefore, the atom site in glass seems fixed, but still has active force that it is promoted to have between atom and arrange again
The trend of column.It is not a stable state, this is different with the state of atom in paraffin.So not equally being crystal, room temperature
Under, paraffin is entirely solid, and glass can be counted as the great liquid of viscosity.
