The present invention relates to a method for producing polyurethane using a homogenizer, intended to minimize a separated amount of N_2 gas contained in crude liquid by disposing {nitrogen + (nitrogen + polyon)} tank (30), an N_2 mixing tank, right before a mixing head (40). According to the present invention, a high pressure fluid is split Into nano-sized microparticles by shear force, warm current, and cavitation in accordance with rapid reduction in pressure, as the fluid passes through a small gap in a valve, thereby reducing levitation force. Thus, quality of products increases without defects, due to liquid existing in a completely uniform state. |
