By mixing Balchip MK and Toughlite RG for mortar spraying, the crack occurrence rate in mortar structures is further reduced!

The mortar reinforcement fiber mixed spraying proposed by K.F. involves mixing polypropylene fibers for mortar reinforcement, "Balchip MK," with crack suppression polypropylene short fibers, Toughlight RG, and spraying them to further reduce the crack occurrence rate in mortar structures, thereby enhancing durability and reducing lifecycle costs. By performing mixed spraying of reinforcement fibers on slopes and other areas, a more permanent weed prevention effect can be expected. 【Why is the crack occurrence rate reduced?】 Reinforcement fibers have various characteristics depending on their type, each with its own advantages and disadvantages. "Balchip MK" has a long fiber length and a rough texture, allowing the mortar to cling to each fiber, making it difficult to pull out and providing crack prevention effects (cross-linking effect). Additionally, as the bending toughness increases, it is possible to omit the wire mesh and reduce the spraying thickness. However, because each fiber is long and thick, the adhesion area within the mortar becomes smaller.

For suppressing shrinkage cracks in sprayed mortar! Safe material made of polypropylene! Crack-suppressing short fibers that can be mixed with a mixer.

Crack suppression polypropylene short fibers, Toughlight, are processed in bundles, making them less likely to scatter and less likely to pierce the skin. Furthermore, since polypropylene is the material used, no toxic gases are generated during combustion, making it a highly safe crack suppression short fiber. 【Incorporation Effects】 ● Reduces scattering and collapse during spraying ● Reduces shrinkage cracks caused by temperature changes and drying during the curing period 【Excellent Workability】 ● Easily mixed with a conventional mixer ● Generates few fiber balls and has high degradability ● The flow value remains unchanged with the incorporation of Toughlight, maintaining fluidity ● During spraying operations, fibers do not pierce like needles due to rebound There are many other features as well!

NETIS Registration Number: CG-070010-A "Kuratec" is a vinyl fiber for reinforcing mortar on slopes. By adding "Kuratec," it is possible to cut the lathing work process depending on site conditions, which can shorten construction time and achieve cost reductions. Additionally, it has good adhesion to cement, making it less prone to cracking, and if cracks do occur, it suppresses their growth. Furthermore, the quality of the mortar improves, allowing for a reduction in the thickness of the spray application. For more details, please contact us or download the catalog to view.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

Seven Corporation has begun research and development related to rust prevention, aiming to expand the functionality of the natural multifunctional aqueous solution "SEA'S 7." This research is being promoted as a collaborative study with the Industrial Technology Research Institute. In recent years, the manufacturing industry has been seeking technologies that balance environmental impact reduction and improved work safety, making rust prevention measures after cleaning a critical issue. This research includes corrosion evaluation using metal test pieces, measurement of weight changes, and durability tests in a circulating water environment, advancing the understanding of rust prevention mechanisms and performance evaluation. In the future, we aim to develop a next-generation SEA'S 7 that incorporates rust prevention functionality in addition to cleaning, disinfection, and deodorization, contributing to the efficiency of manufacturing processes and the reduction of environmental impact.

We are pleased to announce the launch of the "Vertical Aluminum Step Type F." The "Vertical Aluminum Step Type F" is a new type of aluminum ladder specifically designed for excavation sites, based on the existing "Vertical Aluminum Step."

This time, we will explain the differences in roles between the "accounting system" and the "document management system," which are surprisingly not well known, as well as points that are often overlooked in legal compliance. ■ The difference between accounting systems and document management systems is their "scope of coverage." - Accounting System = Management of "money (numbers)" - Document Management System = Management of "evidence (documents)" ■ Documents that are often overlooked in accounting systems The accounting system primarily focuses on "accounting processes." - "Estimates" where no money movement occurs - "Delivery notes" and "purchase orders," which are intermediate points in transactions ⇒ There are cases where these are not saved or managed in the accounting system. This could be considered a deficiency under the Electronic Bookkeeping Act. ■ Supplementing the missing parts with an "independent system" While there are high-function ERP (Enterprise Resource Planning) systems that can manage everything from estimates to invoicing seamlessly, the reality is that the cost can be a significant barrier to implementation. Therefore, there is also the option of managing documents with an independent document management system like paperlogic. Paperlogic is currently offering a free trial. Please feel free to contact us.
