River sand is a non-metallic ore produced by repeated collision and friction of natural stone under the force of water for a long time in its natural state . Its composition is relatively complex, the surface has a certain smoothness, and it is a non-metallic ore with high impurity content . River sand has smooth particles, is relatively clean, and comes from a wide range of sources; river sand has no taste, while sea sand has a salty taste. type River sand is currently divided into: river sand 4-8 mesh, river sand 8-16 mesh, river sand 10-20 mesh, river sand 20-40 mesh, river sand 40-70 mesh, river sand 70-100 mesh. contribute River sand has made outstanding contributions to the construction industry. But sea sand is the opposite. Sea sand is often mixed with shells and salt. Most sea sand contains excessive chloride ions , which will corrode the steel bars in reinforced concrete , eventually leading to the destruction of the building structure and shorten...

Automotive Lubricants，Lubrication, anti-friction and cooling between automotive metal parts

Automotive lubricants are divided into mineral lubricants, synthetic lubricants , semi-synthetic lubricants and other categories. Lubricating oil is prepared from hydrocarbons refined from natural gas and crude oil . There is no clear definition of synthetic oil in the world . Generally, lubricating oil containing PAO is called synthetic oil . Usage performance High-grade lubricants are all synthetic lubricants. Synthetic oil has the following advantages (but the price is higher) 1. Hydrogenated base oil removes impurities that affect the quality of lubricating oil and has stable performance. 2. Improve power, reduce noise, and save fuel than conventional lubricating oil. 3. The fluidity of the oil is twice that of traditional lubricating oil, making low-temperature startup faster. 4. Excellent oxidation resistance and thermal stability , suitable for use under high temperatures and harsh conditions. 5. Excellent anti-wear properties and anti-friction agent formul...

Industrial lubricants

Industrial lubricants have a wide range of applications, and there are many types of base oils, such as: pure mineral oil, PAO polyɑolefin synthetic oil, polyether synthetic oil, alkylbenzene oil, biodegradable lipid oil, when they become certain When making industrial lubricants, they cannot be mixed with each other. For example, after polyether synthetic oil is mixed with other industrial oils, its performance will be significantly reduced. Industrial lubricants have different additives in different applications . Hydraulic oil used outdoors must be suitable for local temperature changes, and hydraulic oil used in indoor closed environments cannot be used. In addition, the usage conditions of heavy-duty gear oil and molding oil are also different. Heavy-duty gear oil contains extreme pressure additives to ensure that it can be used in harsh environments. Molding oil is usually pure mineral oil without additives. composition Lubricating oil generally consists of ...

Tire，Ring-shaped elastic rubber rolling products assembled on vehicles or machinery

Tires are ring-shaped elastic rubber products that roll on the ground and are assembled on various vehicles or machinery . Usually installed on a metal rim, it can support the body, buffer external impacts, achieve contact with the road and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subject to various deformations, loads, forces, and high and low temperature effects when driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, high wear resistance and flex resistance, as well as low rolling resistance and heat generation are also required. Tire development history The birth and development of automobiles is a great achievement of the world’s scientific and technological progress and an important footprint of human progress. It has brought mankind from the era of horse-drawn carriages to an era of automobile industry. In ...
