Core Function and Mechanism
Components such as columns and jacks of hydraulic supports operate under working conditions featuring reciprocating motion coupled with high-pressure loads. Metal friction pairs are prone to adhesive wear, abrasive wear and fatigue wear due to insufficient lubrication, resulting in seal failure or component scrappage.
The core function of lubricant additives is to form a protective film on metal surfaces via physical or chemical adsorption, eliminating direct metal-to-metal contact. Its specific mechanisms fall into two categories:
Additive molecules (such as fatty acids) attach to the metal surface through polar groups, forming a multi-layer molecular film. When the friction pair moves relative to each other, "molecular sliding" occurs between the film layers, significantly reducing the friction coefficient.
Chemical Reaction Coating (For High-Temperature/High-Load Operating Conditions)
When the load is too high or the local temperature rises, the physical film breaks. Additives (such as compounds containing phosphorus, sulfur, and chlorine) react chemically with the metal surface to form chemical films such as sulfides and phosphides. This film has a higher hardness than the metal substrate but is lower than the abrasive particles. It can effectively resist adhesive wear and abrasive scratches.
-Water Soluble Copper Corrosion Inhibitor KHC3042-
KHC3042 is a methyl benzotriazole derivative, soluble in water and ethylene glycol system, used as a metal deactivated agent. It can replace solid Benzotriazole and solid methyl benzotriazole, effectively protect yellow metal and prevent cobalt spillover. Its combination with the conventional carboxylate rust inhibitor can provide corrosion protection for a variety of metals.
All water based systems with PH>7: antifreeze (engine coolant), high water based hydraulic fluid (HFC), water/glycol hydraulic fluid (HFC), metal working fluid (emulsion and synthetic fluid), etc.
The recommended dosage is 0.1%-0.5%.
Easy to operate, suitable substitutes for benzotriazole and methyl benzotriazole.
