Each DreaM invents world’s first true non-combustible fiber reinforced plastic that cleared ISO-1182

Japanese company Each DreaM Company has successfully developed a non-combustible FRP, a long-standing problem in the industry, and has cleared the ISO 1182. They also have the non-combustible heat insulation created during the developing process, which is the only known heat insulation to have cleared the ISO1182 as well. This product is patent pending. This link leads to a simple video demonstrating the product quality: https://youtu.be/EIcD3XGqg2E In the video, the company doused an FRP box containing ice with kerosene and set it on fire. Not only is the box unburnt but the ice inside is still frozen as well. Strictly speaking, it is an FRC (Fiber Reinforced Ceramics) reinforced with basalt cloth. But since it has the same quality and nature as FRPs and could be used as such, they call this material next-generation FRP for convenience. This new material will withstand a 1,500 °C ( 2,732 °F) fire, has low heat conductivity, is poison gas free, and can be easily recycled. FRPs are applied in general vehicle interiors but this nextgeneration FRP not only is non-combustible but, its formaldehyde emission rate is 0.0 mg/L, meaning it is odour free. Apart from the pre-existing FRP, it is expected to be applied in houses and

wooden high-rise buildings. Also, as it can resist a 1,200 °C (2,192 °F) torch despite being 0.8 mm (0.031 inch) thin, it could replace aluminum, its melting point being 660 °C (1,220 °F) depending on its use. Added, they also have a fire proofing liquid that was developed alongside the next-generation FRP. They believe it could have greatly contributed on preventing the fire from spreading and engulfing the mountains in California last year. This liquid will not hinder trees from growing and is safe for animals as it can be rinsed off with water. On 2021, January 23, Saturday, he company demonstrated the quality of this non-combustible next-generation FRP. The event was held in Kihoku-cho, Mie Japan, in the factory premise of the charcoal craftsman; Mr. Tsumura Toshiharu. Mr. Tsumura's Binchotan charcoals are very popular for its high quality and are in high demand around the world. ◆

Think Black: The new black pigment by Colorobbia

Gruppo Colorobbia, this year celebrating one hundred years of history, produces in its modern manufacturing plants located all over the world, a large quantity and variety of pigments (for ceramics, sanitaryware, glass, metal, plastic, etc.) with its own know-how in all production processes. The range of pigments for ceramic use, as always, responds to the market demands and to its customers’ requests, offering multiple solutions for every need. It includes a wide range of items, which can be customized according to the technologies and the desired result. The family of pigments for ceramic use includes those employed for colouring gres porcellanato bodies, which today is considered one of the most interesting product segments thanks to the wide range of uses and proposals available. This series of pigments is used to obtain an infinite number of coloured bodies (black, orange, red, brown, blue, etc.) from soft to more intense tones. Depending on the layout of the customer's plant and the resources available within the wet and/or dry colouring process as well as the characteristics of the final tile, Gruppo Colorobbia offers the pigments of one of the following series: the 6 series for wet dispersion colouring, the 7 series for dry dispersion colouring and the 7x7 series for dry dispersion colouring for high mechanical resistance. A key aspect to highlight is the growing demand for this type of pigments for the mass colouring of large-format slabs, mainly intended for floors and walls. These formats are becoming more and more widespread and are included in proposals for not very conventional uses, outside of traditional ceramics, such as worktops, tables, walls and doors, ventilated façades, etc. To meet the specific needs of the production of large masscoloured slabs, Gruppo Colorobbia has recently introduced the 6 series black pigment PG 64125 in its catalog, which combines technical and colorimetric performance to obtain a wide spectrum of neutral tones in the range from grey to intense blacks of the mass-coloured support, without compromising degassing and dimensional stability, with a low pyroplastic deformation index during the firing temperature phase (1,180-1,220 °C) and keeping constant the water absorption range of the finished tile, regardless of thickness (from 6 to 30 mm). Taking into account the importance of the surface finish of large format slabs, it can also be said that this pigment allows to obtain a coloured substrate on which to develop 100% digital decoration proposals (Full Digital) directly on the support. For all these reasons, PG 64125 is the ideal solution for colouring the black mixtures used in the production of large format slabs. Gruppo Colorobbia, relying on international branches located in the main ceramic clusters in the world, offers a complete service of technical and graphic assistance, customer care, R&D and innovation for the development of projects, and guarantees the most complete transfer of its technical knowhow during the industrial process of its high value added products within its entire customer network. Colorobbia collaborates with leading plant and technology manufacturers and plays a proactive role in testing and implementing new solutions at an industrial level. Gruppo Colorobbia, faithful to its commitment to respect for the environment and to prevent the health and safety of its employees and customers, continues its policy of continuous improvement in terms of reducing emissions and waste, minimizing use of hazardous substances and always respecting the most recent laws and regulations on the classification of substances. ◆

Buehler: Castable (cold) mounting of porous samples for metallography

SimpliVac™, the new castable vacuum mounting system by Buehler – ITW Test & Measurement GmbH, allows impregnation of porous samples or structures more efficiently by means of an automatic cycle control system. The system generates a vacuum – reliably, rapidly and efficiently, and without the need for an external pump. Thus, pores and cracks will be filled completely with epoxy resin, resulting in optimized edge retention for metallographic examinations. The system is also ideal for mounting delicate samples where preimpregnation before sectioning and/or grinding ensures samples are well protected. The number of cycles, the vacuum level and the time under vacuum can be set according to your needs. To optimize the mounting process, multiple cycles can be run without user intervention between cycles. Due to these special features, SimpliVac ensures consistent uniformity, even at high throughput, and reduces the time required to complete the mounting process. The large chamber diameter allows simultaneous mounting of multiple small samples. Alternatively, SimpliVac can also accommodate samples with larger dimensions. Its compact and small footprint allows more space on the lab bench. The new vacuum impregnation system offers cold mounting solution of test samples to both quality control and/or research laboratories. Examples include electronics components, thermal spray coatings, additive manufactured components and other specialty aerospace surface treated test samples. Technicians or metallographers will appreciate the ability to optimize sample impregnation in a faster, more automated way. SimpliVac is easy to use. A video showing its simple operation is available at https://youtu.be/5bphC-lyUxY When it comes to hot compression mounting, the equivalent of the new SimpliVac is the SimpliMet™ 4000 by Buehler, for quick and reliable use. It is ideal for demanding industrial environments, both in terms of sample throughput and mounting quality. Buehler – ITW Test & Measurement GmbH, Esslingen/Germany has been a leading manufacturer of instruments, consumables and accessories for metallography and materials analysis since 1936, and also supplies a comprehensive range of hardness testers and hardness testing systems. A dense network of branch offices and dealers means our customers can rely on professional assistance and service around the world.
