20-50℃ 之间高搅(1,000 - 2,500 rpm, 5-25 min. depending on viscosity)。Too high speed may result in destruction of the active fibers and reduced performance, but too low shear will result in extended incorporation times.
Excessive dispersion times will result in a gradual decline in the final properties of the coatings.
预分散制浆
按配方量先将聚酰胺蜡浆分散在一部分树脂中,使用low to medium shear rates.然后this dispersion can be added to
finished paints.
This incorporation method is preferred for coatings prepared using
specialty pigments such as aluminium powder, flatting agent, and zinc dust.
