  • The main performance characteristics of polyurea-based grease

    The main performance characteristics of polyurea-based greases 1. The main performance characteristics of polyurea-based greases Polyurea greases are a new type of grease made from urea-based compounds thickened base oils and have the following properties. 1. Excellent high temperature resistance, its dropping point can reach above 270 ~ 300 ℃, polyurea-based grease is more suitable for high temperature lubrication. 2. Polyurea-based grease with excellent antioxidant properties

  • Small grease package meets filling requirements

    The small grease package meets the requirements of filling. (1) The barrel of the small grease package should not be collected too much toward the center, otherwise it will be unfavorable for sealing the box. (2) The vertical teeth of the cover are sufficiently protruding to prevent screwing. The capper slips when unscrewing. Small grease packaging needs to meet the needs of storage and transportation. Because of the harsh storage and transportation conditions of grease,

  • What fillers are used in grease

    What are the filler greases, thick grease-like semi-solids. It is used in the friction part of the machine for lubrication and sealing. It is also used on metal surfaces to fill voids and prevent rust. It is mainly composed of mineral oil (or synthetic lubricating oil) and thickener. The main purpose of adding grease to the filler is to improve the lubricity of the grease and enhance the sealing and protection of the grease.

  • Reasonable selection of grease

    Reasonable selection of grease is very important. Grease is a thick, grease-like semi-solid. It is used in the friction part of the machine for lubrication and sealing. It is also used on metal surfaces to fill voids and prevent rust. It is mainly composed of mineral oil (or synthetic lubricating oil) and thickener. 1. The operating temperature of the grease should be at least 20-30 degrees below its dropping point. When the operating temperature is high, it should be selected.

  • Three main factors that lead to high temperature grease loss

    Three main factors that lead to high temperature grease loss High temperature grease generally belongs to synthetic grease and contains high concentration of polytetrafluoroethylene lubricating particles. It has high temperature and pressure resistance and is suitable for high temperature and heavy load equipment. This fluorine high temperature grease is specially used Bearings in high temperature, high load, chemically corrosive environments and components requiring lifetime lubrication, with good chemical inertness, durability and low volatility

  • Explanation of mass changes in grease storage

    1. Quality changes in grease storage After long-term storage, the grease has the following quality changes: 1) changes in color; 2) mixed with mechanical impurities such as lime sand, dust; 3) mixed with water or absorbed water: 4) long-term storage After the lubricating oil is precipitated, it becomes a hard mass, oil and soap separation occurs, acid substances are generated, and corrosion is unqualified. 2. Lubrication caused during storage

  • What are the precautions for storage of grease?

    1. What are the precautions for storage of grease? 1. The package should be well sealed to avoid the intrusion of moisture, dust and oxidative deterioration of grease. 2. When handling and loading and unloading grease, it should be handled as lightly as possible. It is recommended to stand upright to avoid heavy fall and do not roll along the edge of the barrel. 3. Grease should be stored indoors as much as possible to avoid sunlight and rain, no indoor storage for the time being

  • What fillers are used in grease

    What fillers are used in grease? The main reason for adding fillers is to improve the lubricity of the grease, enhance the sealability and protection of the grease, increase the strength of the grease, reduce the amount of grease thrown from the friction parts, and improve lubrication. Grease stability and reduced coefficient of friction. Before using grease fillers, they are usually dispersed, classified, purified, and activated. Used as lubrication

  • Purchase instructions for high temperature grease

    1. The operating temperature of high temperature grease should be at least 20 to 30 degrees below its dropping point. When the operating temperature is high, a grease with good oxidation resistance, small evaporation loss and high dropping point should be selected. When the operating temperature is low, a low start-up should be selected. Moment, similar low viscosity fats, such as greases based on synthetic oils. 2. The selected high-temperature grease should be compatible with the speed of use of the friction pair being lubricated.
