Cum Clave analysis N.03 preview.
After 12 weeks of full-scale trials a new wear lining material, developed by First Graphene and its partner new Gen Group for use in the mining and quarrying industries, is demonstrating how graphene is transforming the properties of conventional rubber products, according to the companies.
The PureGRAPH® graphene enhanced rubber is known as Armour-GRAPH™ and liners made from this material are being tested in buckewheel excavator reclaimer buckets at a major iron ore mine in Australia, where they are being used alongside standard wear lining materials to demonstrate the advantages of graphene additives. The graphene is an additive used in thermoset PU rubber to improve the performance of the bucket liner used in the reclaimer buckets. The reclaimer buckets are one major application for PureGRAPH® in mining equipment wear linings.
Results after 12 weeks of intensive testing are impressive, as Craig McGuckin, Managing Director of First Graphene, explains: “This is a particularly aggressive environment, where sacrificial wear liners in mining buckets, hoppers and chutes have to be replaced at frequent intervals; this leads to unwanted downtime and significantly increases operating costs…..
The addition of graphene to elastomers can have a dramatic impact on their mechanical and physical properties. This can include, for example, an improvement of up to 500% in abrasion resistance, an increase in tensile strength by 40% and tear strength by around 50%. These enhancements can be achieved with just a 1% blend of graphene, by volume, to the rubber compound…
Stablecoin : Tether
Tether has been the first stablecoin that was born with the idea to be stable enough to save its purchasing power in the crypto world against a FIAT currency. In its simplest of forms, Tether, is a cryptocurrency with a fixed price measured by a fiat currency, in the first case, the U.S. Dollar. Today we find also Tether pegged with other FIAT currency like Chinese yuan (CNH). It’s symbol on the exchanges is USDT and it has a capitalization of around 4 Billion EUR.
Overall considerations on the currency is that without stability, a seller will be skeptical of trading goods and services for fear of losing value due to price volatility—one of the reasons why cryptocurrencies haven’t been widely adopted yet. All the other cryptocurrencies are not reliable for making day-to-day transfers due to high volatility in price.
Tether coins in circulation are backed by an equivalent amount of traditional fiat currencies, like the dollar, which are held in a designated bank account. It operates on the Omni protocol as a token issued on the blockchain. At the early life of Tether every Omni transaction was recorded in the Bitcoin blockchain, while nowadays Ether blockchain is the one used with the standard ERC-20…
