What are the characteristics of the application of dimethyl silicone oil?
Dimethyl silicone oil is a kind of hydrophobic organosilicon material. Due to its unique properties, it is widely used in our lives. What are the characteristics of dimethyl silicone oil as an antifoaming agent and a lubricant?
-
As an antifoaming agent: Because dimethyl silicone oil has a low surface tension and is insoluble in water, animal and vegetable oils, and high-boiling-point mineral oils, it has good chemical stability and is non-toxic. As an antifoaming agent, it has been widely used in industries such as petroleum, chemical engineering, medical treatment, pharmacy, food processing, textile, printing and dyeing, and papermaking. Only 10 - 100 PPM of silicone oil needs to be added to have a good antifoaming effect.
-
As a release agent: Due to the non-adhesiveness of dimethyl silicone oil to rubber, plastics, metals, etc., it is also used as a release agent for the molding and processing of various rubber and plastic products and in precision casting. Using it as a release agent not only makes demolding convenient but also makes the surface of the products clean, smooth, and with clear textures.
-
As a lubricant: Dimethyl silicone oil is suitable for being used as a lubricant for rubber, plastic bearings, and gears. It can also be used as a lubricant for the rolling friction between steel and steel at high temperatures or when steel rubs against other metals. However, since the lubricating performance of methyl silicone oil is not particularly good at room temperature, generally speaking, it is not recommended as a lubricant between metals at room temperature.
-
As an additive: Dimethyl silicone oil can be used as an additive for many materials. For example, it can be used as a brightening agent for paints. Adding a small amount of silicone oil to paints can prevent the paint from blistering and wrinkling and improve the brightness of the paint film. Adding a small amount of silicone oil to inks can improve the printing quality. Adding a small amount of silicone oil to polishing oils (such as car polish) can increase the brightness, protect the paint film, and have an excellent waterproof effect.
Dimethyl silicone oil is widely used in our lives and has brought a lot of convenience to our lives. At present, there are already hundreds of derivatives of dimethyl silicone oil. This is not the end. In the future, there will be more derivatives of dimethyl silicone oil, and its applications will be even more extensive.
