Mining, manufacturing, processing, and selling of calcium carbonate and natural zeolite.

Nitto Funka Shouji Co., Ltd. has been engaged in the mining, manufacturing, processing, and sales of calcium carbonate (CaCO3) since its establishment. In Japan, which has limited resources, limestone is considered a unique resource, and Nitto Funka Shouji Co., Ltd. owns particularly valuable pure white crystalline limestone mines at each of its factory locations. The high quality and reserves of this limestone are the company's greatest pride and its most significant asset. Furthermore, a passionate team of research and technology has created the "superfine particle NS," which can be said to have established the "heavy calcium carbonate" industry in contrast to "light calcium carbonate." Following this, the company has developed various new products, including surface treatment products such as the "Nobelite NCC" series, granulated products like the "Carpet" series, and submicron "Nitrex" series products that rival colloidal calcium carbonate, consistently leading the industry as a top manufacturer and a comprehensive producer of calcium carbonate, boasting quality, technology, and quantity both domestically and internationally. 【Products Offered】 ○ Calcium Carbonate ○ Natural Zeolite For more details, please contact us or download the catalog.

Aluminum hydrous silicate minerals that contain water molecules as a main component in the form of crystalline water within their structure.

The name "zeolite" is derived from the Greek meaning "boiling stone" and is also referred to as "boiling stone" in another name. Zeolite is a hydrated aluminum silicate mineral that contains water molecules (H2O) as a main component in the form of crystal water within its structure. When heated suddenly, it bubbles and melts, appearing as if it is boiling, which is how it got its name. The crystal water in zeolite exists as water molecules within the three-dimensional network structure of zeolite, and is specifically called "zeolite water." Even when dehydrated by heating, the structure of zeolite is not destroyed, and the areas where crystal water was present remain as cavities, resulting in a sponge-like structure that has the property of strongly adsorbing gases and moisture again. 【Features】 ○ Even when dehydrated by heating, the structure of zeolite is not destroyed, and the areas where crystal water was present remain as cavities, which have the property of strongly adsorbing gases and moisture again. ○ The cation exchange capacity is not affected by the surrounding environment (such as pH) and has the property of sustaining that capacity for a long time. ○ It is an effective and beneficial material for purifying the earth, water, and air by adsorbing pollutants.

Are you making progress on measures for the "2024 Problem"? The management of drivers' working hours is becoming stricter, and in the logistics field, reducing "waiting time for loading" has become an urgent issue. To address this challenge, our company, Hotron, proposes the "Vehicle Detection Ultrasonic Sensor 'HM-UX2'," which instantly grasps the availability of loading bays. The 'HM-UX2' contributes to the resolution of waiting times by accurately understanding the availability status, reducing unnecessary waiting and queuing, and shortening waiting times, thereby alleviating the burden on drivers! By replacing the "eyes" of your loading bay management with this high-precision sensor, why not start taking measures against the "2024 Problem"? Take a look at the product features: "Can it accurately detect availability?" "Can we really use it in our company?" "I just want to know the cost, even if it's an estimate." If you have any questions or requests, please feel free to consult us first.
