ÕâÊÇÎÄÏ×µÄÌâÄ¿ºÍÕªÒª£º Impregnation of glass rovings with a polyamide melt. Part 2: Wipe-off die A process for the impregnation of glass rovings with a polyamide melt is studied in which the glass rovings were led over spreader pins in a melt bath and then through a wipe-off die. A set-up was made to measure the pulling forces. The degree of impregnation of the bundle before it entered the die, the bundle size, the die size and the pulling speed were varied to determine their effect on the friction forces and the impregnation of the wipe-off die. With a dry bundle no impregnation is obtained in the die and the friction forces are low. If a partially impregnated bundle is led through the die, the impregnation is enhanced, but the friction forces are high. |
