摘要
合成一种鏻盐鞣剂,研究了其在超声波作用下的无铬鞣反应;分别考察了pH值、超声时间以及超声强度等对试样湿热收缩温度(Ts)的影响。结果表明,在一定pH值条件下,超声波作用可提高无铬鞣试样的Ts,且可缩短鞣制时间,提高效率。当提碱pH为7.5时,试样的Ts达82.7℃。超声波鞣制的合适反应条件为超声强度200 W,超声时间60 min。
The ultrasonic assistant tanning effect of a tetrakis hydroxymethyl phosphonium（THP） tanning agent synthesized in laboratory was studied. The influence of pH, reaction time and the intensity of the ultrasonic wave on the shrinking temperature （Ts） were experimented respectively. The results indicated that at certain pH the ultrasonic wave assistant tanning increased the Ts of the leather, furthermore the tanning time was shortened thus the tanning effect increased. The Ts of the leather reached 82. 7 ℃ when tanning pH is 7. 5. The applicable tanning condition is that the intensity of the ultrasonic wave of 200 w and the tanning time is 60 min.
