Directory of companies by products - Plastic Greases

Greases Greases lubricants are the consistency of paste

consisting of base oil and thickener to improve certain properties of the additives. Significant additions include: ◊ oxidation and corrosion inhibitors ◊ adhesion additives ◊ High-pressure additives ◊ additives to protect against wear ◊ solid lubricating components (graphite

MoS2

PTFE) The right combination of base oil

thickener and additives determines the properties of grease. Greases based on calcium soaps Their application covers a temperature range from approx. -40 ° C to 60 ° C with very good water resistance . If these greases heated above 60 ° C to soften without cooling after restore their texture. For many years used for general lubrication of chassis cars ( except for wheel bearings )

today is already in decline. Greases based on sodium soaps They are suitable for application temperatures up to approx. 100 ° C. In the past

quite often used for lubricating the "hot" bearings were now replaced in these applications greases based on lithium soaps . They are not water resistant . They have a fibrous structure and

therefore

are intended primarily for the lubrication of gears. In short heating above the point melting and cooled to restore its initial structure. Greases based on lithium soaps Calcium complex greases On the basis of their good compatibility with water

likes to use the "wet" applications. At higher temperatures and longer storage tend to be hardening

through mostly used for deleting a loss of permanent domazávaním . The maximum application temperature is 130 ° C short term 140 ° C. Aluminum complex greases Very well proven in high temperature applications around 150 ° C

even when using heat- stable base oils can also handle short-term peak temperature 200-220 ° C. In combination with a solid lubricating components

such as MoS2 or graphite

are often used in rotary furnaces and transmissions in other temperature -bearing lubrication applications

often in metallurgical industry . Because of their very good resistance to water are used in lubrication engineering and water shipping .
