New graphene solid lubricants can be used to reduce friction and wear on steel surfaces

Researchers have created a new class of non-liquid lubricants that have been shown to significantly reduce friction and wear under extreme conditions. They can be used in many applications such as air compressors and missile systems. The new liquid-free composite is made from a slurry of graphene, zinc oxide and polyvinylidene fluoride. Graphene is an extremely thin carbon layer with many potential technical uses, including lubrication. According to Vilas Pol, associate professor of chemical engineering at Purdue University, USA, “It has excellent thermal conductivity, high strength and ultra-low friction. Chemical engineering graduate student Arthur Dysart said that the nano-scale zinc oxide developed by the R&D team. The particles cause the lubricant to adhere to the metal surface and the polymer binds the entire mixture together. Many machines require solid lubricants, such as air compressors, equipment used in the food industry, spacecraft, gears and chain mechanisms, in high temperature environments. Fasteners, missile systems, high-speed printers, hydraulic motors in winches, cranes and military vehicles, high-performance shredders and rigs. Farshid Sadeghi, a distinguished professor of mechanical engineering at Purdue University, said: "The root cause of mechanical failure is Friction and wear, so reducing these factors can improve the performance and service life of many mechanical systems. “Although liquid lubricant technology has advanced, it cannot be used in high temperature or low pressure situations, such as vacuum environments, so dry solid lubricants are a viable alternative to liquid lubricants in extreme operating environments.” The researchers tested the coating Stainless steel surface with new lubricant. Abdullah A. Alazemi, a graduate student in mechanical engineering, said: "We tested in the most demanding situations. The durability and resilience of this adhesive coating demonstrates the excellent potential as a dry lubricant for high load bearing machinery. "(Compile: China Superhard Materials Network)

Aluminium Sulphate are sweet white shiny crystals, granules or powder. It's stable in the air.but easily soluble in water, almost insoluble in ethanol, and the solution is acidic. Aluminum sulfate is a widely used flocculant in the purification of drinking water and Sewage Treatment equipment, as well as in the paper industry.

Aluminium Sulfate is a new, high-quality, high-efficiency iron salt inorganic polymer flocculant. The water purification effect of Aluminium Sulfate is perfect.The water treated by Aluminium Sulfate is free of harmful substances such as aluminum, chlorine and heavy metal ions, and no water phase transfer of iron ions, non-toxic, harmless, safe and reliable.

Aluminium Sulfate produced by JINHE Industry has obvious effect on purification of micro-pollution, algae-containing, low temperature and low turbidity raw water, especially for high turbidity raw water.And the dosage is small, the cost is low, and the processing cost can be saved by 20% -50%.

In the paper industry, it is used as a precipitant for rosin gum, wax emulsion and other rubber materials, as a flocculant in Water Treatment, and as an internal retention agent for foam fire extinguishers. It is also used as a raw material for the production of industrial aluminum sulfate alum and aluminum white. Raw materials for certain drugs, etc. Aluminium Sulfate can also be used in manufacturing artificial gems and high-grade ammonium alum. Aluminium Sulfate produced by Jinhe Industry can be used in water treatment flocculants too.
