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.

Second-hand car，Old Motor Vehicle
Second-hand vehicles refer to motor vehicles that are registered with the public security and traffic management agencies, have been in service before reaching the scrapping standards stipulated by the state or within their economic and practical life, and can still be used.   Second-hand car, translated into English as “Second Hand Vehicle” or Used Car, means “second-hand car” or “used car”, and is called “old motor vehicle” in China . “Middle-hand cars” is what Japan calls them, but Taiwan, China, also calls them “second-hand cars.” North America is the most developed market for second-hand cars. Because ordinary people may not necessarily be able to buy “second-hand” cars when they buy used cars, and most of them are cars and family jeeps, so in North America they are commonly called “second-hand cars”. Used cars”.   The government work report proposes to extend the preferential...
