Abstract
The invention provides a foaming technology used in plastic sheet material processing. According to the invention, magnetic material powder is added to a raw material used in plastic sheet material processing. During a foaming stage, the materials are irradiated by using electromagnetic waves, such that foaming is carried out. According to the invention, with an energy absorption principle of the magnetic material powder, the effect of the foaming aid can be effectively promoted, and foaming efficiency can be improved. With the technology, a defect of traditional foaming that the temperature window is not easy to control is overcome, such that the foaming process is energy saving, time saving, convenient, and highly efficient.
Description
Technical field
The invention belongs to the plate product manufacture field, be specifically related to the foam process in a kind of sheet material work flow.
Background technology
In conventional plastic sheet material process of manufacture, to the foaming of sheet material generally in conjunction with special blowing promotor, the operation of in specific blowing temperature window, foaming.Therefore increase the step of plastic plate production and processing, also correspondingly increased the time of production and processing.
Summary of the invention
At above the deficiencies in the prior art, the invention provides the foam process of the plastic plate processing that a kind of technology is simple, foaming effect is good.
The present invention is achieved by the following technical solutions:
The foam process of a kind of plastic plate processing adds magnetic material powder in the raw material of plastic plate processing, utilize the electromagnetic wave irradiation operation of foaming at foaming stages.
Described electromagnetic wave is a microwave.
Beneficial effect of the present invention is: utilize magnetic material powder energy absorption principle, promote having an effect of blowing promotor effectively, and improve foaming efficient, can solve the uppity shortcoming of traditional blowing temperature window, make the foaming operation procedure, time-saving energy-saving, efficiently convenient.
The specific embodiment
Be foaming intensity and the foaming efficient that improves plastic plate processing, the present invention adds magnetic material powder in the raw material of plastic plate processing, foaming stages utilize electromagnetic wave irradiation sheet material is carried out in heating reaching the effect of foaming, this moment, the sheet material internal structure reset type.Our experiments show that, when using microwave, the best results of foaming.And different according to sheet material raw material and blowing promotor, the waveband selection of microwave is also slightly different.
The present invention utilizes magnetic material powder energy absorption principle, promotes having an effect of blowing promotor effectively, and improves foaming efficient, can solve the uppity shortcoming of traditional blowing temperature window, makes the foaming operation procedure, and time-saving energy-saving is efficiently convenient.
Claims (2)
1. the foam process of plastic plate processing is characterized in that adding magnetic material powder in the raw material of plastic plate processing, utilizes the electromagnetic wave irradiation operation of foaming at foaming stages.
2. the foam process of plastic plate processing according to claim 1 is characterized in that described electromagnetic wave is a microwave.
