Detailed Product Description: | Introduction: extreme pressure and anti-wear agents TH726 is the introduction of foreign advanced production technology, using thiadiazoles heterocyclic compounds and aromatic ester compounds as a synthesized oxadiazole derivatives containing ester groups thiophene, due to the product structure containing thiophene oxadiazol heterocyclic and ester conjugated effect, and therefore the product can be formed on the metal surface protective film has a double effect of a metal deactivator, antioxidant and extreme pressure and antiwear, suitable for use in the lubricating oil esters used as a metal deactivator anti-wear and extreme pressure additives. Lubricant extreme pressure and anti-wear agent more effective additive TH726 outstanding anti-wear extreme pressure performance and good antioxidant effect, and the compatibility with other additives, can be used for turbine oil, hydraulic oil, gear oil, engine oil a variety of oils in order to improve its anti-oxidation and anti-wear properties; grease extreme pressure additives. Friction performance mechanism: thiadiazole derivatives containing ester groups TH726 four-ball tester investigated their tribological properties as hydroxy lithium stearate grease extreme pressure and anti-wear agents, and XPS, SEM and EDS analysis frictional properties of the surface. The results show that, added to the ester group-containing thiadiazole derivatives hydroxy lithium stearate grease anti-wear, anti-friction and anti-sintering properties have been significantly improved. This is due to friction additives in the friction process chemical reaction, the reaction product is formed on the metal surface layer of the joint action of the adsorbed film having antifriction properties of the film, and the metal surface results. The extreme pressure and antiwear agent TH726 can be provided in the friction surface to form a protective film (adsorption or reaction of the film), to thereby prevent direct contact between the metals, as well as play a role in the antiwear and extreme pressure resistance. In many of the extreme pressure and antiwear agents, thiadiazole derivatives increasingly attentions thiadiazole derivatives are a class s, N heterocyclic compound, has a close and stable structure, the bearing capacity and good lubricating properties. Such additives without P and heavy metal elements, ashless additives, also has a metal antioxidant, metal passivation, and many other features. Basic lipid, in the initial stage of the frictional coefficient of friction with increasing time, increases may be due to increase of friction initial stage of the real contact area is caused by friction; the friction experiment 10min, the friction coefficient increases gradually gentle This is because the basic ester oil film so that the friction coefficient remains stable. Containing basis ester containing T321 and T351, the initial stage of the friction, the coefficient of friction with increasing time increasing friction test 10min after the adsorption film of the film and additives of the basic esters of the basis ester friction coefficient stable ; friction experiment 20min, the coefficient of friction of the two base ester were reduced, but may be due to the additive contained active element formed with the role of the heat friction surface chemical reaction film due. There are elements in the friction surface of a thickness of about (1 m), O and S, the friction generated on the surface is the adsorption film is formed with the metal surface with their interaction or reaction membrane. This film has a better anti-wear extreme pressure. From time results, the thiadiazole derivative of the ester group-containing basic ester PD to be larger than the T-containing basic ester PD value, with excellent extreme pressure and antiwear properties. Physical and chemical properties of indicators are as follows: the indicators data numerical parameter standard appearance of brown viscous liquid brown viscous liquid measured effective content ≥ 98% 98.2 HPLC viscosity mm2 / s 13.-15.5 14 GB / T 265 Flash point (open) ℃ ≥ 180 ℃ 186 ℃ GB/T1671 chroma Pt-Co) # ≤ 100 80 GB/T1664 copper in corrosion 100C, 3h) 1 Grade 1 GB / T 5096 Package and transportation 25KG / barrel, 200KG / barrel.
