A kind of foam production mechanical foaming machine
Technical field
The invention belongs to foam production technical equipment field more particularly to a kind of foam production mechanical foamings
Machine.
Background technology
Foamed plastics is a kind of high molecular material formed in solid plastic by bulk gas micropore dispersion, has matter
The characteristics such as gently, heat-insulated, sound-absorbing, damping, and dielectric properties are better than matrix resin, have many uses.Almost various plastics can be made
Foamed plastics, foaming have become a key areas in plastic processing.It can be divided into closed pore, trepanning and net by its foam structure
Shape foamed plastics.All abscesses of closed cell foamed plastic are nearly all disconnected.All abscesses of open cell foamed plastic are nearly all
Connection.The foamed plastics that there's almost no cell wall is referred to as reticulated foam.It can be divided into low hair by the density of foamed plastics
Bubble, middle foaming and high-foaming foamed plastics.Foamed plastics is using polymeric material of the plastics as basic component and containing a large amount of bubbles
Material, therefore could also say that the composite plastic using gas as filler.Compared with pure plastics, it has many excellent performances, such as
It is light, specific strength is high, absorbable shock loading, heat-insulated and sound insulation value are good etc..Thus in industry, agricultural, building, communications and transportation
Equal fields are widely applied.
There are many foaming methods of foamed plastics, and three kinds of foaming methods of most common of which have physical blowing method, chemistry hair
Bubble method and mechanical foaming method, wherein mechanical foaming method are that air is driven into resin using strong mechanical agitation, make its at
For uniform foams, then gelling is made using physical and chemical changes, final curing is current at foamed plastics
Plastic foam mechanical foaming machine is there are cumbersome, mixing efficiency is low, the non-uniform disadvantage of mixing, therefore there is an urgent need for research and develop a kind of behaviour
Make foam production mechanical foaming machine convenient, that mixing efficiency is high, uniformly mixed.
