聚氨酯膠粘劑是指在分子鏈中含有氨基甲酸酯基團(tuán)(-NHCOO-)或異氰酸酯基(-NCO)的膠粘劑。聚氨酯膠粘劑分為多異氰酸酯和聚氨酯兩大類。多異氰酸酯分子鏈中含有異氰基(-NCO)和氨基甲酸酯基(-NH-COO-),故聚氨酯膠粘劑表現(xiàn)出高度的活性與極性。與含有活潑氫的基材,如泡沫、塑料、木材、皮革、織物、紙張、陶瓷等多孔材料,以及金屬、玻璃、橡膠、塑料等表面光潔的材料都有優(yōu)良的化學(xué)粘接力。

Inline viscosity measurements can give continuous, realtime readings of a fluid’s viscosity during processing and consequently, can provide a means to automate the viscosity control of process fluids. While it is difficult to control all factors in the process that can affect a fluid’s viscosity (such as temperature, air bubbles, shear history, turbulence and so on), if these factors are kept relatively constant, then good control can be achieved.
