Article Preview

In this article, konjac flour, super absorptive resin and pellet urea were added into flexible polyurethane foamed plastic with polyether polyol and isocyanate as the raw materials by a new water-foamed technology to manufacture a kind of absorptive and biodegraded polyurethane foamed fertilizer. Polyurethane foam was used as a carrier material and konjac flour was used as a biodegradable agent. The results showed that the slow-release velocity of urea could be controlled by regulating the densities of polyurethane foams, the content of konjac flour and super absorptive resin. The carrier material could be degraded konjac flour by naturally.
