EVA resin is widely used. In general, the content of vinyl acetate is below 5%, and its main products are film, wire and cable, LDPE modifier, adhesive and so on.The content of vinyl acetate is 5%~10% of EVA product is elastic thin film, etc.The content of vinyl acetate is 20~28% EVA, mainly used for hot melt adhesives and coating products.The content of vinyl acetate is 5%~45%, the main products are film (including agricultural film) and sheet, injection molding, molding products, foaming products, hot melt adhesives and so on.

Sheet extruder

1、Parameter

1) extruder production capacity Q: the amount of plastic extruded per hour.

2) ratio flow: extruder production capacity per hour per hour.

3) nominal power: the motor power required to process kg plastic per hour.

4) screw length ratio L/Db: the length of screw working part and screw diameter ratio.

5) screw diameter Db: means large diameter, series standard 20, 30, 45, 65, 90, 120, 150, 165, 200, 250, 300.

6) drive screw motor power P:KW.

7) screw speed range :nmin-nmax r/min.

2, model

150/20 indicates that the diameter of the screw is 150mm and the diameter ratio is 20:1.

Single screw extruder, as a kind of common extrusion machine equipment, used for plastics processing industry, single screw extruder generally on the effective length is divided into three sections, according to the screw diameter, screw pitch, the depth of screw to determine three Duan Youxiao length, generally divided each accounted for a third.Efficient single screw extrusion machine adopts double cascade overall design, strengthen the function of plasticizing and pledge the stable extrusion, high speed high performance special barrier mixing design, integrated to ensure the material mixing effect, high shear and low melting plasticizing temperature to ensure the materials of high performance low temperature low pressure measurement.High speed and high yield extrusion on high flat foundation.
