说明:TH561l是在T561的升级替代产品,活性硫含量可达到33%以上,金属减活剂TH561L以巯基噻二唑,长分子链烷硫醇等为原料在大分子主链中引入SN等具有抗磨活性的杂原子,经复杂氧化偶联反应制得的黄褐色透明液体。该产品具有极好的极压抗磨性、抗氧性、抗腐性及降低金属活性的能力。比传统的噻二唑衍生物 T561抗氧化性能优良,改性噻二唑衍生物TH561具有较好的溶性,能在铜表面形成完整的保护膜,对铜材具有较好的缓蚀作用.广泛应用于汽车发动机油,齿轮油及金属切削液中做金属减活剂,在润滑油中,作极压抗磨剂,能显著抑制润滑油在使用过程中产生的硫化物的腐蚀性,是*的抗氧化剂,用于抗磨液压油、低温液压油、汽轮机油和汽油机油中作轴承防腐剂、抗磨剂及金属减活剂
用于乳化液中作极压剂、细菌和氧化抑制剂,用于内燃机油中作抗氧剂。其特点是低剂量、高性能,在油品中使用与有色金属表面作用形成保护膜,极为有效地防止添加剂中活性硫和氧化作用产生的酸性物质对金属引起的腐蚀。同时,也抑制了金属及金属离子对油品的催化氧化作用,使其丧失活性质点。

Lubricant additive TH561(Thiadiazole Derivatives)

CHEMICAL NAME: 2,5-bis(n-octyldithio)-1,3,4-thiadiazole dioctyl disulfide

CAS NO: 13539-13-4

Molecular Formula: C18H34N2S5

SPECIFICATION:

Transparent liquid,It provides the lubricant with preferable antiwear, anti-oxidation, anti-corrosion and metal deactivation.

1. DESCRIPTION
The product is a transparent liquid, prepared from 2,5-dimercaptothiodiazole and thioalcohol. It provides the lubricant with preferable antiwear, anti-oxidation, anti-corrosion and metal deactivation performance.

2. APPLICATIONS:It is used primarily for anti-wear hydraulic oil, low-temperature hydraulic oil, turbine oil and gasoline engine oil, serves as anti-corrosion agent, antiwear agent and metal deactivator; used as extreme pressure agent, bacteria and oxidation inhibitor in emulsion; and antioxidant in internal combustion engine oil.The dosage is from 0.3% to 0.4%.

3. CHARACTERISTICS                                                                     Excellent performance of anti-oxidation and copper corrosion inhibition In hydraulic oil, it can significantly reduce the copper corrosion from ZDDP and settle hydrolytic stability.In internal combustion engine oil, it can improve the anti-oxidation ability of paraffinic oil.

4. STORAGE: Store in dry, clean and ventilating warehouses. Please refer to SH/T0164, for transportation, storage and oil blending. Keep the temperature not higher than 60°C. For long-term storage the suggested temperature is lower than 50°C. The dry, clean  and ventilating warehouse is recommended.

USAGE:lubricant additive;lubricant antioxidant additive;antifriction oil additive; lubricant extreme antiwear additive.
