  • 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.

  • 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 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

  • Analysis and Evaluation Method of Grease

    The physical and chemical properties of grease mainly refer to the appearance and consistency of the grease, the corrosion of metals and the compatibility with synthetic rubber. Testing the appearance of grease can make a preliminary distinction between various types of grease and preliminary judgement of the quality of grease

  • How to choose high temperature grease?

    How to choose high temperature grease? High temperature resistant grease is an ester synthetic oil thickened by an organic thickener that is excellent in low temperature performance. This low temperature grease is mainly designed for the lubrication of precision equipment that requires low movement and running torque at low temperatures, providing good rust and corrosion protection. Applicable temperature range:

  • High temperature grease products are mainly used in the following areas

    Introduction of high temperature grease High temperature grease generally belongs to synthetic grease. It contains high concentration of polytetrafluoroethylene lubricating particles. It has high temperature and pressure resistance and is suitable for high temperature and heavy load equipment. Bearings in chemically corrosive environments and components requiring lifetime lubrication have good chemical inertness, durability, and low volatility. Applicable temperature range

  • Separation of grease

    Separation of grease is like grease. The role of grease is mainly to lubricate, protect and seal. Most greases are used for lubrication and are called antifriction greases. Anti-friction grease is mainly used to reduce mechanical friction and prevent mechanical wear. At the same time, it also plays a protective role against metal corrosion and a seal against dust. Some greases are mainly used to prevent metal from rusting or decaying

  • What are the reasons for the grease's water resistance?

    What are the reasons for the grease's water resistance? Grease, thick, oily, 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. Water resistance of grease depends on the type of thickener and base oil.

  • Analysis of grease loss solutions and three major causes

    Analyze the solution of grease loss and the three major causes of grease, 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. There are three main reasons for the loss of lubricating grease: chemical reasons, physical factors and impurities.
