Description
Technical field
The present invention relates to foaming technique field, more particularly to a kind of using the machine that shapes in polymer
The interior processing method producing microbubble.
Background technology
In general, the foam pattern of polymer generally can be distinguished into following three types：First
Type is mechanical foaming, mainly by mechanical strong agitation, makes gas be uniformly mixed into polymerization
To form bubble in thing, second type is physical blowing, to mainly use physical blowing agent in polymerization
In thing, forming bubble, the third type is chemical blowing, mainly uses for produced physical change
What CBA decomposed after being heated that the gas discharging to promote polymer is internally formed bubble.
It is different from aforementioned three kinds of modes, such as previously had Taiwan I233877 patent announcement to be in conveying
Bury an air shooter in screw rod, then install multiple micro-porous permeable blocks in the front end of conveying screw rod, when
Gas-pressurized can carry out indirectly heat, through too high through an electric heater after entering in air shooter
By each micro-porous permeable block, gas is exported to fluid polymer again after temperature heating, make gas with conveying
The stirring of screw rod and mix with fluid polymer, finally reinject in a mould, so can
Reach the effect forming bubble in polymer.
But in aforementioned patent bulletin, micro-porous permeable block be embedded in the middle of air-vent and with conveying spiral shell
Generally assume, between the surface of bar, the state being mutually flush that is to say, that micro-porous permeable block can only connect
