Slaked lime for slurry that solves the "de-toxification" and "settling" of neutralization engineering!

"Slalric" is a high-concentration calcium hydroxide for slurry that is surprisingly smooth despite its high concentration. It features excellent dispersion when dissolved in water and has high dispersibility that makes it resistant to settling over time. It maintains low viscosity even at a high concentration of 50% w/w. Since the main component is slaked lime, there is no need to handle hazardous materials or toxic substances. It is provided in powder form, allowing for concentration adjustments tailored to the equipment and applications at the usage site. 【Features】 ■ High dispersibility: Resistant to settling over time ■ Low viscosity: Maintains low viscosity even at a high concentration of 50% w/w ■ Flexible concentration adjustment: Provided in powder form, allowing for concentration adjustments based on equipment and applications ■ Safe and easy management: No need to handle hazardous materials or toxic substances *For more details, please download the PDF or feel free to contact us.

Precise control of secondary particle size to below 10μm! Achieving smooth blending into thin film.

We would like to introduce "fine particle calcium hydroxide" that we handle. It is a food additive equivalent calcium hydroxide, which has antibacterial effects due to its alkalinity and gas adsorption effects for hydrogen sulfide, hydrochloric acid, and other gases. As a result of evaluating a product with 10% added to LDPE sheets, we confirmed an antibacterial effect with a reduction rate of over 99.9% against E. coli. It is also available as a masterbatch. 【Features】 ■ Antibacterial effect due to alkalinity (slightly soluble in water: pH 12.4) ■ Substance used as a food additive ■ Gas adsorption effects for hydrogen sulfide, hydrochloric acid, and others *For more details, please download the PDF or feel free to contact us.

It demonstrates excellent vulcanization promoting effects!

"META-Z" is an active zinc oxide produced through wet synthesis. Compared to regular zinc oxide, it has a fine particle size and a large specific surface area, demonstrating a high vulcanization promoting effect, resulting in excellent rubber properties depending on the formulation. We offer two types as vulcanization promoting agents for rubber: active zinc oxide "META-Z 102" and the composite active zinc oxide "META-Z L" series. [Features] ■META-Z L - Composite type active zinc oxide - Cost advantages - Low specific gravity, etc. ■META-Z 102 - Fine particles with a large specific surface area - High vulcanization promoting effect (improved crosslink density) - Enhanced rubber properties such as tensile strength and compression set, etc. *For more details, please contact us.

In "The Principles of Mixing and Defoaming and Key Points for Recipe Setting," we will explain the mechanism of the self-rotating and orbiting mixer, Awatori Nentaro, and the principles of mixing and defoaming in an easy-to-understand manner for beginners. ◇ Why do materials mix just by combining centrifugal force? ◇ What does it mean that mixing and defoaming can be processed simultaneously? ◇ How do the materials inside the container move during operation? This content is recommended for those who usually use Awatori Nentaro in their work but have never heard about its mechanism or principles and want to learn about it on this occasion. We will also explain temperature management based on material viscosity and considerations for operating conditions with examples. Additionally, in the "Legal Self-Inspection and Basic Maintenance Training," participants will have the opportunity to experience basic maintenance such as round belt replacement and legal self-inspection (regular self-inspection) using actual equipment. The capacity for each seminar is different, so please apply early! ◆ Date and Time: April 24, 2026 (Friday) 13:00 - 16:30 ◆ Venue: Hiroshima Convention Hall
