Abstract
The present invention relates to a kind of plastic plate and the internal stress removing method of bar, including following methods：1) plastic plate or bar are layered evenly distributed dress basket, it is ensured that interlayer well-ventilated；2) basket that will install plastic plate or bar is discharged in stress elimination stove；3) stress elimination stove is warming up to 120 DEG C first, the heating-up time is 4 hours, is incubated 4 hours afterwards；Insulation is heated up again after 4 hours, and stress elimination stove is warming up into 150 DEG C, then the heating-up time is 4 hours, is incubated 4 hours again afterwards, is finally cooled to room temperature.The internal stress removing method step of plastic plate of the invention and bar is simple; by in plastic plate or bar input stress elimination stove; temperature control is carried out according to three-stage temperature curve; making the arrangement of the molecule and nucleus of plastic plate or bar becomes orderly; then lowered the temperature with slowly speed again, in practice it has proved that the plastic plate or bar its internal stress for so treating can be released with major part.
Description
Technical field
The present invention relates to a kind of plastic plate and the internal stress removing method of bar.
Background technology
Its material internal all can be this with the presence of larger internal stress after thermoforming for thermoplastic engineering plastic sheet material and bar
The presence of internal stress is to later stage of material using leaving very big hidden danger.The modeling not processed by good elimination internal stress
Material material be machined out when be easily deformed and burst, the workpiece for processing its size is also easily varied, and precision cannot
Ensure, or even when northern area winter, the major diameter bar of production if not carrying out stress-removal treatment in time,
There is also bar and burst situation about hurting sb.'s feelings.In consideration of it, find a kind of rational internal stress removing method being just particularly important.
The content of the invention
In order to solve the above technical problems, the present invention provides the internal stress removing method of a kind of plastic plate and bar.
The internal stress removing method of plastic plate of the invention and bar, including following methods：
1) plastic plate or bar are layered evenly distributed dress basket, it is ensured that interlayer well-ventilated；
2) basket that will install plastic plate or bar is discharged in stress elimination stove；
3) stress elimination stove is warming up to 120 DEG C first, the heating-up time is 4 hours, is incubated 4 hours afterwards；Insulation 4 hours
After heated up again, stress elimination stove is warming up to 150 DEG C, then the heating-up time is 4 hours, is incubated 4 hours again afterwards, is finally dropped
Warm to room temperature.
Beneficial effects of the present invention are compared with prior art：The internal stress elimination side of plastic plate of the invention and bar
Method step is simple, by plastic plate or bar input stress elimination stove, temperature control is carried out according to three-stage temperature curve, makes
The arrangement of the molecule and nucleus of plastic plate or bar becomes orderly, is then lowered the temperature with slowly speed again, in practice it has proved that
So treated plastic plate or bar its internal stress can be released with major part.
Brief description of the drawings
Fig. 1 be a kind of plastic plate described in the embodiment of the present invention and bar internal stress removing method in stress elimination stove
Structural representation；
Fig. 2 be a kind of plastic plate described in the embodiment of the present invention and bar internal stress removing method in stress elimination stove
Temperature control curve.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the invention is described in further detail.Hereinafter implement
Example is not limited to the scope of the present invention for illustrating the present invention.
As shown in Figure 1-2, a kind of internal stress removing method of plastic plate and bar, including following methods：
1) plastic plate or bar 1 are layered evenly distributed dress basket, it is ensured that interlayer well-ventilated；
2) basket that will install plastic plate or bar 1 is discharged in (as shown in Figure 1) in stress elimination stove 2；
3) stress elimination stove 2 is warming up to 120 DEG C first, the heating-up time is 4 hours, is incubated 4 hours afterwards；It is incubated 4 small
When after heated up again, stress elimination stove 2 is warming up to 150 DEG C, then the heating-up time is 4 hours, is incubated 4 hours again afterwards, most
After be cooled to room temperature, as shown in Figure 2.
The internal stress removing method step of plastic plate of the invention and bar is simple, should by plastic plate or bar input
Power is eliminated in stove, and temperature control is carried out according to three-stage temperature curve, makes the arrangement of the molecule and nucleus of plastic plate or bar
Become orderly, then lowered the temperature with slowly speed again, in practice it has proved that the plastic plate or bar for so treating are inside it
Stress can be released with major part.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of the technology of the present invention principle is not departed from, some improvement and modification can also be made, these are improved and modification
Also should be regarded as protection scope of the present invention.
