This document discusses "why powder compacts." It introduces two types of compaction: true compaction and pseudo compaction, as well as internal factors such as moisture content and hygroscopicity, and external factors such as atmospheric relative humidity and temperature during packaging. The mechanisms of compaction and the factors that cause it are explained in detail. We encourage you to read it. [Contents] ■ Mechanisms of Compaction 1. True Compaction 2. Pseudo Compaction ■ Factors Causing Compaction - Internal Factors (moisture content, hygroscopicity, particle morphology) - External Factors (atmospheric relative humidity, temperature during packaging, stacking pressure, storage duration, others) *For more details, please refer to the PDF document or feel free to contact us.

Do you know why bagged materials harden? There are two types of hardening: true hardening and pseudo hardening. Internal factors such as moisture content and hygroscopicity, as well as external factors like atmospheric humidity and temperature during packaging, can cause this. The 'Momikura' handled by Shinko Kasei is a bagged material crushing machine that can return hardened powder materials to powder form in just 4 seconds without removing them from the bag or cardboard. It requires only simple maintenance with oiling. It eliminates manual crushing work, significantly reducing running costs. [Example of crushing results] *Please refer to the PDF for the list ■ Ethylene urea ■ Sodium nitrite ■ Paratoluene sulfonic acid ■ Granulated sugar ■ Sodium citrate Rental options are also available, which can help prevent product defects due to hardening and complaints from users. *For more details, please refer to the PDF or feel free to contact us.
