Development and Performance Evaluation of Ballpoint Pen Cartridge Grease
With the continuous increase in ballpoint pen production capacity,China has become a globally recognized pen manufacturing powerhouse.Under the strong support of relevant government departments and related policies,the technical barriers hindering the independent development of China's ballpoint pen industry,such as ballpoint pen ink and component processing technology,have been gradually broken down.However,at the present stage,domestic research on pen cartridge grease is still in its infancy,and mid-to-high-end pen cartridge grease products still mainly rely on imports from abroad.Therefore,a high-performance pen cartridge grease product was developed using inorganic thickeners and silicone oil-based base oils as raw materials,with the addition of a certain amount of modifiers to enhance its stability.Compared with a certain high-end pen cartridge grease product from abroad,it has better high and low temperature properties,anti-volatility,viscosity-temperature characteristics,and storage stability.Through pen-loading test,its performance was comprehensively evaluated.The developed pen cartridge grease shows good performance in terms of high and low temperature stability,impact resistance,and writing responsiveness,which can fully meet the usage requirements of ballpoint pens.(Charts8 Tables6 References12)
