Complete plastic recycling systems

A standard plastic recycling system just will not exist. Period Lines can be quite similar, because machinery will be the same, but elements may differ, sometimes a lot, based on man power, energy, water, space availability, production rate, final software of the product some more, could be less important but effecting operating cost anyway. So, […]

Problems in the Process of PVC Foam Board Extrusion

Poor stability shall affect the complete board, board can be yellow and the foam sheets’brittleness is large. Insufficient melt strength will cause the cell of foamed sheet becoming bigger and the longitudinal section bulbs longer. The most direct way to judge whether the melt strength is insufficient is to press the sheet wrapped in the […]

Extruded vs Expanded foam What’s the difference

There are various iterations of foam: rigid, plain styrofoam sheets, extruded, and expanded. The after two, expanded and extruded, are probably the most used in terms of home building projects, but what’s the difference? mixer extruder Expanded called Beadboard Often, sheets are produced from solid beads of polystyrene. These beads happen to be expanded by […]

Foam Granulation part 2

extrusion systems The aqueous foamed binder used in foam granulation is made up of a high volume of gas dispersed within a liquid containing foamable excipients, thus forming an unstable, semi-rigid structure. Effective excipients for pharmaceutical granulation happen to be cellulose-ether species that promote large foaming activity and become binders along the way. Many approved […]

XPS insulation boards begin as a good granule. The granules will be fed into an extruder where they’re melted and critical additives are blended with the viscous liquid that is formed. Then, a blowing agent is undoubtedly injected to make the combination foamable . Under thoroughly controlled heat and pressure conditions, the foamable combination is […]

Extrusion Foaming System for Fabricating OpenCell Structure

plastic sheet extruders Low Density Polyethylene foam of open-cell type was manufactured through extrusion foaming system utilizing a physical blowing agent for the application of sound absorption. For the purpose of enhancing the open cell content, salt powder was blended with LDPE changing the particle and content size. Scanning electron microscopy analysis was completed in […]

Foam Granulation part 3

single screw extruder A scholarly analysis at pilot-scale flow rates compared foamed-binder addition and direct liquid-injection on granulation. A methylcellulose binder was employed at two concentrations, 6% and 11%, relative to a-lactose monohydrate powder. Two screws were analyzed in the work to produce differing axial compression characteristics with changing flow level: one with a single […]
