Pengaruh Quality Surface Starch Terhadap Runability Sizer
ABSTRACT
Currently the pulp and paper industry is experiencing rapid development. On the other side, raw materials are increasingly difficult to obtain. Therefore, the use of raw materials must be regulated as optimally as possible. The production process is regulated as efficiently as possible in order to reduce company expenses. The observations made this time discuss the effect of surface starch quality on the runability of the sizer. Sizer is a tool used for applying surface sizing chemicals to paper sheets that aim to modify the surface properties of the paper. The types of starch used in PM #3 are corn starch, wheat starch, and tapioca starch. Problems that often occur with corn starch are the amount of dust that accumulates from using starch, much dirt on the filter, so we have to clean the filter more often and the corn starch quickly reacts with other chemicals. In wheat starch, foaming often occurs when cooking with high temperatures so that there is an overflow, foaming can be caused by the characteristics of wheat starch, such as small particle size. Moreover, tapioca starch is more stable, but sometimes causes a streak on the surface roll top and bottom sizer. With the low consumption of starch, enzyme dosage, and defoamer flow in tapioca starch and cooking starch system in PM #3, which is auto cooking with a short route, tapioca starch is more cost-effective in production and easier to control. The highest runability of sizer without a break is tapioca starch. From this observation, it can be concluded that the best surface starch quality for the sizer runability is tapioca starch.
