The Effect of ZDDP and MoDTC Additives on the Friction Performance of DLC Coatings and Steel Cam Followers in Engine Oil – The Unique Role and Effect of MODTC Additives
Conduct friction tests using a pin plate test bench to simulate the sliding conditions of the cam follower. In the case of SAE5W-30 engine oil, the friction coefficient of steel pins sliding on steel discs increases from 0.11 to 0.12, while the friction coefficient of steel pins sliding on diamond-like carbon (DLC) coated discs decreases…
New phosphorus-free builder – modified sodium disilicate (MDS)
Detergents are widely used daily chemical products. According to relevant data, my country’s annual output of laundry detergents has reached 4 million tons, 90% of which are phosphorus-containing laundry detergents that use sodium tripolyphosphate (STPP) as a builder. Laundry powder is the main source of phosphorus pollution in rivers and lakes. Controlling or switching to…
