東洋ユニオン Product Lineup

There is a wide variety of equipment related to dry ice blasting cleaning and other necessary materials for construction, allowing for quick responses to various maintenance demands.

In the film coating and drying process, dirt inside the drying oven can cause a decrease in airflow and the dropping of foreign objects, negatively impacting product quality. Inside the film drying oven, resin components, solvents, and additives that evaporate during drying become sublimates (tar) and adhere to the walls, circulation fans, and slit nozzles. Our dry ice cleaning service completely removes and cleans these stubborn deposits by utilizing the thermal contraction of dry ice and the expansion force during sublimation, without using any water or solvents. Since it is a dry cleaning process, there is no need for a drying stage after cleaning, enabling rapid maintenance that also considers fire risk and worker safety. Here is the case study document on quality improvement through the removal of tar and sublimates inside the film drying oven.

The dryer section of the film manufacturing and processing line is prone to dirt adhering due to heat, which can lead to transfer onto the film and a decrease in thermal conductivity. Using dry ice, we clean the resin residue, sizing agents, and various coatings that have baked onto the heating rolls and guide parts of the film dryer, without damaging the base material. Since there is no concern about grinding the base material, we can safely clean while protecting the high-precision mirror surface of the dryer rolls. We provide cleaning services that minimize line downtime, directly contributing to the recovery of drying efficiency and improvement of product yield. Here are the performance materials for improving the drying efficiency of film dryers and roll cleaning.
