ITRI has successfully developed high performance lubricant to address the extreme demands for the operations under heavy-load and low speed conditions. The detrimental effect of tribological behavior can’t be overlooked due to its adverse increase to the maintenance and repairmen cost. ITRI is welcome any potential partners with mutual beneficial proposal either engaged in the distribution channel or manufacturing sector.

It’s reported that there are one third of energy loss due to useless friction, 80% damaged parts worn-out by wear and over half of the machine breakdown caused by inadequate lubrication. According to Professor Jost, the author of the Jost Report, an one-time investment on tribology study could have 20 times return per year by the cost reduction arising from solving the problems originated from friction, wear and bad lubrication. The additives in the lubricant can play the significant roles of friction reduction, anti-corrosion and heat dissipation, and hence increase the equipment life and mitigate the environmental pollution.

Contact information Features of the technology

The lubricant with small amount of nano-diamond additives manufactured by ITRI proprietary surface modification technology can meet the demand of ever increasing complication of nowadays machinery. Particularly in the heavier load and higher precision requirements, nano-diamond added lubricant can serve the purpose for low wear, low temperature and energy saving tribology effect. The following diagram illustrates the de-agglomeration of aggregated diamond into a single diamond crystalline particle.

  • The functional group modified surface can enhance the de-aggregation effect to keep nano-diamond dispersed persistently in the lubricant oils, and spontaneously adhere to the metallic surface to form a protection layer. With the diamond intrinsic properties of anti-friction, low friction coefficient and endurance to high load and high temperature, nano-diamond can effectively reduce the energy loss by mechanical friction, lower the wear rate and abrasion damage
  • This is a green lubricant without heavy metals and other anti-wear additives

Contact information Notes for using our products

  • During regular maintenance of oil change, adding our product to the lubricant oil by a ratio of 5%, e.g. by adding 200ml into 3~4 liter lubricant oil
  • Avoid messing up with water and impurities
  • Be cleaning the engine thoroughly to maximize the effect, i.e. to remove heavy carbon deposit, paint film, oil sludge, gelatinous layer, etc. before application
