Abstract
Устройство и способ получения полиуретанкарбамидных полимеров на водной основе в динамическом смесителе, который имеет поворотно-лопастную турбину внутри отсасывающей трубы, что создает осевой поток, которые используются для диспергирования в воде полиуретанового форполимера с концевыми изоцианатными группами. Смесители сконструированы таким образом, что обеспечивают среднюю продолжительность пребывания по крайней мере около 10 с, среднюю удельную мощность перемешивания менее, чем около 0,60 Вт/см и среднее число проходов через зону смешения по крайней мере около 5-ти.A device and method for producing water-based polyurethane carbamide polymers in a dynamic mixer that has a rotary vane turbine inside the suction tube, which creates an axial flow that is used to disperse the polyurethane prepolymer with terminal isocyanate groups in water. The mixers are designed in such a way that they provide an average residence time of at least about 10 s, an average specific mixing power less than about 0.60 W / cm and an average number of passes through the mixing zone of at least about 5.
