       Waste Polystyrene Foam can be Recycled

       Polystyrene packaging materials are mostly disposable, used to
       become waste. And the following are some methods of the
       recycling of waste polystyrene foam.
       ① Re-processing to reuse
       Polystyrene foam has two molding methods: one is the direct
       foaming method, and the other is the expanded beads method. Both
       of these methods are physical processes that do not destroy the
       polystyrene polymer structure, so that it remains the original
       nature. So Styrofoam

       />is a good way to reuse it. Take waste fast food box as an
       example, the process of  the recycling is:
       Waste fast food box &#8594; washing &#8594; drying &#8594;
       crushing &#8594; forced feeding &#8594; pre-plasticized &#8594;
       extrusion plastic (head with quick change filter) &#8594;
       forming &#8594; cooling &#8594; granulation &#8594; bagging
       &#9313; To produce the cement products
       The surface density of waste polystyrene foam is 20 ~ 25kg / m³,
       after processing the wet density of concrete is 220 ~ 270kg /
       m³, which basically equivalent to the expansion of rock, the dry
       density can also be greatly reduced, There is no special
       requirement for the blended cement.
       &#9314; The preparation of paint
       Polystyrene transparency is up to 90%, and the refractive index
       is 1.59 ~ 1.60, use it to coated with polypropylene, abs and
       other plastic for vacuum coating primer, can improve the height
       of plastic parts of the plating film, of course, it can also be
       used to produce general anti-rust paint and furniture paint.
