<p>A waste PVA foam recycling process to crashes the waste PVA foam into evenly distributed grains, then grains are placed into a molding die while a PVA mixing agent is added into grains. Both of the agent and grains are polymerized, heat dehydrated and hardened into an integral compound to create friction resistance between soft and hard components for removing pollutants. The PVA foam grains can be further admixed with color grains to create merchandisable patterns. Therefore, the present invention, by reclaiming the waste PVA foam and to producing zero pollutant recycled PVA foam with economic value.</p> |
