抄録

From the result of previous study authors found that suitable amount of oily matter on the particle surface is a necessary factor for the standard carbon black and that the difference of raw material's quality or preparing method is not important factors.<BR>Considering this result, authors prepared a simple combustion furnace of lampblack method type.<BR>Preparation of the carbon black with ample amount of oily matter and uniformity on the quality was always successful when naphthalene was burned at 400500°C in this furnace by the adjustment of ventilator. The prepared carbon black was extracted with acetone for 40 hours to adjust the amount of oily matter on the particle surface, and then it was compared with the Tamagawa C carbon. The characteristics of the prepared carbon black were superior than Tamagawa's in the following points;<BR>1. The diameter of the primary particle size was smaller.<BR>2. The deviation of particle size was less.<BR>3. The amount of oily matter was more.<BR>4. The quality of soiled cloths was more uniform.<BR>5. The difference in detersive efficiency between washing in water and washing in soap solution appeared nearly the same as that of Tamagawa's in the case of soiling by machine, but appeared much more in the case of soiling by hands.
