  Engineers from the SSAB steel-making company have unveiled the world’s first piece of steel cast without burning any coal or fossil fuel. Instead, they used hydrogen to power the process. Metalworking and coal burning have been entwined for as long as humanity has been using metals. Coal is a very good source of energy, providing the heat necessary to refine and process most metals. But it is also a source of carbon, a critical chemical in the production of steel, and the compound that allows us to turn metal ores (usually oxides) into actual metals (by leaching out the oxygen). For most of our history, this wasn’t that much of an issue. Coal smoke is definitely not healthy for you or anyone living near the smeltery or ye olde blacksmith, but overall production of metals was limited in scope — so the environment could absorb and process its emissions. Today, however, the sheer scale at which we produce metals means that this process has a real impact on the health of th...

  A worker is still unaccounted for after a large fire and several explosions on 27 August severely damaged buildings at Leeson Polyurethanes plant in Leamington Spa, UK. As of 2 September, emergency services had not been able to access the site to investigate the cause or search for the missing man, as it is still unsafe. Local residents were temporarily evacuated but returned to their homes the following day once the fire was under control. Air monitoring suggested there was a minimal hazard, although residents were warned that soot and debris could be irritants. Cleanup of soot and debris in the surrounding area by the local authorities is ongoing.  Source: chemistry world

  Hexagon Agility, a Hexagon Composites company, signed an agreement in June 2021 with Xpress Natural Gas LLC (XNG), a full-service provider of compressed and renewable natural gas in the United States, to deliver its Mobile Pipeline® modules for the clean natural gas transportation.  Under this contract, Hexagon Agility received its second XNG order, worth an estimated $ 2.8 million.  The modules are expected to be delivered in the fourth quarter of 2021. “The TITAN 53s has allowed us to make clean natural gas accessible and affordable for our customers, keeping businesses running and homes warm during the cold winter months.  Hexagon's products have proven to be of high quality - safe, reliable, and high performing, ”said Jeffrey Ciampa, XNG's chief operating officer.  " The TITAN® 53 modules offer the highest capacity in North America and will serve multiple projects to communities and industries that do not have access to natural gas or lack sufficient pipel...

Hanwha Cimarron LLC will build a new $130 million production facility in Alabama to produce large-scale tanks for hydrogen transport, filling stations, and support expansion into tanks for UAM, drones, launch vehicle rockets, defense, rail, cargo ships, transportation and more. Hanwha Cimarron currently manufactures large tanks for compressed hydrogen gas as well as tanks for cryogenic fuels used in space launch vehicles. This acquisition is part of Hanwha Solutions’ efforts to accelerate its expansion into the green-hydrogen industry. The company reports that Hanwha Cimarron provides the technology to manufacture tanks for hydrogen tube trailers, ultra-high-pressure tanks for hydrogen filling stations and tanks for aerospace applications, as well as for hydrogen-powered vehicles. “Including the acquisition costs, we plan to invest at least $100 million in Cimarron Composites by 2025 to establish a strong foundation from which to develop our global hydrogen tank business,” said...

  Scientists are working on   carbon fibres   made from   biomaterials   instead of fossil fuels in an attempt to create a version that does not generate   carbon   emissions. Bio-based carbon fibres could be used to build lightweight electric cars with greater battery range, according to senior scientist Dr Erik Frank. In architecture,  concrete  could be reinforced with carbon fibres instead of  steel , allowing ultra-thin structures to be built. "It's a wonder material because it is very strong and yet light compared to metal," said Frank, who is head of carbon fibre development and new materials at the  German Institutes of Textile and Fiber Research  in Denkendorf, southern Germany. However, "the carbon footprint of carbon fibres is usually very bad," he added. "The raw materials [for regular carbon fibre] come from petroleum but we're trying to move away from this," he explained. "Bio-based carbon fibres are in much highe...

  LYOCELL FIBER : A well-known Chinese manufacturer is offering Lyocell fiber since 2010 and has increased its production capacity up to 30,000 tpa in recent years. Features of lyocell Fiber: Lyocell fiber has good characteristics of dry strength, wet strength, and high wet modulus which possesses the softness of cotton,lustre of silk, smooth of hemp. It has good hygroscopicity, fine drape, strong abrasion resistance, and good spinnability which is easy to be dyed. Interested buyers/textile companies are looking out to buy lyocell fiber, please reach out at rosaram211@gmail.com to have TDS and other technical information.

  📢Time to Get Technical...📢 Let's learn more about filament winding! Filament winding consists of winding continuous rovings of fiber onto a rotating mandrel in predetermined patterns. This method of manufacturing provides the greatest control over fiber placement and uniformity of structure. The mandrel configuration corresponds to the internal surface of the component to be produced. Material compaction is accomplished owing to the component of the tensile stress normal to the mandrel surface. Material layers are formed with each wind offset with respect to the previous one across the width. Also, the winds are placed on the mandrel in a state of static balance (they keep it in place without sliding.) The winding pattern is formed by periodically repeated winding cycles, with subsequent cycles offset relative to one another across the winding-tape width. The mandrel is then covered with winds uniformly along the maximum component diameter, excluding gaps and filament overlaps....
