Principle and steps of silicone oil emulsion
The principle of silicone oil emulsion is based on emulsification technology, which combines silicone oil with appropriate emulsifiers to dissolve in water and form an emulsion. The following are the principle steps of silicone oil emulsion:
1. Emulsifier selection: Choosing the appropriate emulsifier is a key step. Common emulsifiers include surfactants, surfactants, or colloidal substances, which have hydrophilic and hydrophobic moieties that can reduce surface tension between liquids and promote the emulsification process.
2. Preparation of emulsion: Mix silicone oil and emulsifier in a certain proportion, and emulsify them by mechanical stirring or ultrasonic treatment, so that the silicone oil is finely dispersed in the aqueous phase to form an emulsion.
3. Stable emulsion: The function of emulsifiers is to reduce the surface tension between liquids, avoiding droplet aggregation and separation. During the emulsification process, it is necessary to control the concentration and emulsification time of the emulsifier in order to obtain a stable emulsion liquid.
4. Application of emulsion: Stable silicone oil emulsion can be directly applied to fields that require lubrication, anti adhesion, anti-corrosion and other functions. According to specific needs, different emulsion formulas and concentrations can be selected.
