Due to the different conditions and requirements of the environment and occasions used, Dongsheng Oil Seal tells you that the rubber oil seal used in the oil seal has different media, this also determines the environment and occasions for the use and application of oil seals developed and produced. in the industry, it is common to develop and produce several rubber oil seals for oil seals, rubber is made of Ding Qing rubber oil seal, acrylic and fluorine rubber oil seal. The oil seal materials that can be selected outside the rubber category include silicone rubber oil seal material, polyurethane, hydrogen Ding Qing rubber material and PTFE rubber oil seal material (Oil Seal lip part)Wait.Let's mainly look at the performance of the oil seal made of Ding Qing rubber?What environment and occasions are the main applications of such oil seals?
First, what are the performance features of the oil seal made of Ding Qing rubber?
The oil seal made of this rubber material has excellent oil resistance (Such as mineral oil, animal and vegetable oil, liquid fuel, etc).It has good wear resistance, good heat resistance, good aging resistance, good physical and mechanical properties and good chemical stability, among which the heat resistance is better than that of natural rubber oil seal, styrene-butadiene rubber and neoprene, use and operate in environments and occasions up to 120 degrees Celsius.
Two, what are the shortcomings of the oil seal made of Ding Qing rubber?
The disadvantage of the oil seal produced by Ding Qing rubber is that the cold resistance performance is poor (Glass transition temperature is-55 degrees Celsius)Poor odor resistance and electrical insulation can not withstand the corrosion of acidic liquid/gas phase media at high temperature.
Third, the oil seal made of Ding Qing rubber is used in what industry?
Due to the large number of oil seals, the quality of oil seals has exceeded that of similar oil seals abroad.Due to its own features and price advantages, the industry has a large application field of oil seal material. This type of oil seal is widely used in aerospace devices, liquid petroleum gas pipelines, Transformers, cylinder heads, etc, especially in the field of hydraulic and pneumatic transmission industry.
