What is dry lubrication?

Dry film lubrication is to form a solid lubricating coating on the surface of the friction pair by means of physical deposition, chemical reaction or evaporation deposition, so that friction occurs between the lubricating coatings, so as to achieve friction reduction and wear resistance. Solid coatings include polytetrafluoroethylene (PTFE), DLC film, MoS2 coating and so on. The solid lubricating coating can be prepared on the surface of the friction pair of different materials (metal, paper, wood, rubber, plastic, glass, etc.) to form a uniform lubricating film, and at the same time play a role in waterproof, moisture-proof, corrosion-proof and cleaning.

What is PTFE coating?

In order to prevent the fasteners of mechanical equipment from corrosion and rust, many manufacturers choose some anti-corrosion coatings to deal with it. However, compared with conventional anti-corrosion materials, PTFE coatings can be applied in relatively harsh corrosive environments and have a type of anti-corrosion material that can achieve a longer protection period than conventional anti-corrosion coatings.

PTFE coating has excellent heat resistance and low temperature resistance. It can be used at -255℃~290℃, and can withstand high temperature to 300℃ in a short time. Generally, it can be used continuously between 240℃~260℃. The thermal stability, it can work at freezing temperature without embrittlement, and does not melt at high temperature.

PTFE coating can make fasteners have better anti-corrosion ability, avoid bolt rusting and delay the failure cycle, and make installation and disassembly easier. Excellent performance in harsh corrosive environments, so it is widely used in the surface anti-corrosion treatment of fasteners in petrochemical, nuclear power, electric power, natural gas and offshore oil platforms, and underwater equipment. After testing: In the ASTM B-177 salt spray test, the PTFE coating lasted for 2500 hours, and the red embroidery area was less than 15%, which achieved excellent results.

The insulation strength of the PTFE coating can reach 500-1200 volts per microinch (mil), thereby achieving the effect of inhibiting electrochemical corrosion. In addition, the PTFE coating has superior UV resistance and weather resistance, and can also prevent the corrosion of fasteners caused by hot soil layers and most chemicals.

PTFE coating has excellent lubrication performance, the friction coefficient can be as low as 0.05, and it can provide long-term lubrication for rotating workpieces under high pressure, and can reduce the installation torque to a certain extent, thus prolonging the service life of the workpiece.

The ptfe coating hardly adheres to all substances, and the thin film also shows good non-adhesion performance. Therefore, the workpieces treated with this coating are basically free of water and oil, even if there is a small amount of dirt, it is simple It can be removed by wiping, thus saving man-hours and improving work efficiency.

PTFE dry lubrication has the following characteristics:

(1) Clean, colorless, and oil-free, suitable for clean keyholes, plastic tracks, window and door tracks, zippers, tools, plastic chains, office equipment, toys, home appliances, auto parts, medicine, etc;

(2) High temperature resistance, no soft flow at high temperature, suitable for injection mold thimble, switch components, home appliances, electronic equipment, optical instruments, etc;

(3) Resistant to oil, water, and other chemical acid and alkali liquid corrosion, high adhesion, suitable for food and beverage, chemical equipment, paper industry, wood, textile and packaging industries;

(4) Lubrication in vacuum environment, such as laminator rails;

(5) Good lubrication performance, can provide long-lasting protection against friction and wear, extend the service life of parts and equipment, and improve their working efficiency.
