Lubricants on the base of calcium complex sulfonate with modified thickener structure Andrey Yasnovsky, Technical Director, TOTAL Lubrifiants Russia and CIS


Слайд 1

Requirements of the European market concerning the main types of lubricants Resistance to high temperatures Super high pressure Corrosion protection Water resistance Self-recovery Mechanical stability and resistance to shift Good pumpability (providing the pressure in the centralised lubricant feed system is no lower than 60 bar) Cost requirements: the average cost of lubricant with a Ca thickener does not exceed 10% - 25% of that of the most widespread Li thickener, even though it has higher operating attributes


Слайд 2

(R - SO3)2Ca + CaCO3 (amorphous phase) + promoting agent + polar solvent ? (R -SO3)2Ca + CaCO3 The process of slow homogenisation is very important for the future stable operation of the lubricant (TOTAL Ceran) Thickener: basis of the technology


Слайд 3

Thickener – base (standard) Calcium sulphonate (composite)


Слайд 4

Vaterite Calcite A poor barrier for water Possible forms of CaCO3 Unstable system The secret of the thickener – stable conditions of homogenisation, observance of the technology


Слайд 5

New technologies: the additive is a part of the thickener Ca Ca Ca Ca Ca Ca Ca Ca Ca Ca Ca Carbonate Organic chains Size: 50 - 120 нм Additives and admixtures


Слайд 6

Advantages of the composite thickener technology


Слайд 7

Qualitative improvement of indications


Слайд 8

TOTAL CERAN : Properties Advantages of the composite calcium thickener with modified additives. Anti-wear properties Anticorrosion properties Thermal stability Protective properties Extreme pressure Mechanical stability Service and storage life


Слайд 9

High-temperature attributes Dropping point CERAN – Wide temperature range of application


Слайд 10

High operational attributes – broad capabilities for use Ferrous and non-ferrous metallurgy Woodworking and paper production Application in marine units and mechanisms Heavy-duty bearings
