Extrusion foaming technology is realized through an extruder by using the principle of pressure-reducing foaming. Starch and water and other additions After the agent enters the extruder, under the joint action of heat and shear, the crystalline structure of
the granular starch is destroyed and forms A disordered melt of starch polymers, the so-called thermoplastic starch. Due to the extrusion of the screw and the cavity of the extruder limit, the heated starch melt will build up a high pressure, making the water in it a superheated liquid (temperature temperature up to 220°C) without vaporization. When the starch melt is extruded from the head of the extruder, the pressure in the material is released, the superheated water vaporizes and evaporates instantly,forming a porous structure in the starch melt. At the same time, the material temperature The decrease and increase of the glass transition temperature of the material due to water evaporation makes the thermoplastic starch return from the highly elastic state to the glass glassy state, thereby freezing the porous structure in it to form a foam material. Preparation of Starch Foam by Extrusion Foaming Technology Packaging materials began in the late 1980s, and then a number of starch foam materials were prepared by extrusion foaming technology.The patent of the material comes out. This method is currently the starch foam loose filling material (loose filling material) used in the production of cushioning packaging.
The main method of fill:
Final product: Different corlor starch based foam pacakage stuffing filler
2. Capacity: 180-400kg/h
3. Voltage in China
Three phases: 380V/50Hz, Single phase: 220V/50Hz, we can make it according to customers'local voltage according to different countries.
4. Machines Materials
All the machines are made by food grade stainless steel. This line is with reasonable design and with high automation; the screws are made by alloy steel, with building block system structure and self-cleaning function.
5. Raw Materials
Raw material:the packing stuffing filler making machine are used corn starch,cassava starch and other starch as the main
ingredients.
