Liquid silicone is a commonly used material widely used in various industries. However, sometimes the fluidity of liquid silicone is not ideal and practical methods need to be taken to increase its fluidity. Below, we will introduce some common methods and explain them with examples.
Firstly, the fluidity of liquid silicone can be increased by adjusting its viscosity. Viscosity is an important indicator of liquid fluidity, usually adjusted by changing the formula of liquid silicone. For example, adding a certain proportion of diluent during the preparation process can effectively reduce the viscosity of liquid silicone and improve its fluidity. Taking a certain home appliance company as an example, they used the method of adding diluents when producing liquid silicone earphone covers, successfully increasing the fluidity of silicone and improving production efficiency.
Secondly, the fluidity of liquid silicone can be increased by controlling its temperature. Temperature has a significant impact on the viscosity of liquid silicone gel. Generally, an increase in temperature leads to a decrease in the viscosity of liquid silicone gel, thereby increasing its fluidity. For example, a car parts manufacturing company found that the fluidity of liquid silicone was not ideal during the production process, so they took heating measures. By setting up appropriate heating equipment on the production line, the temperature of liquid silicone was raised, which successfully improved fluidity and enhanced product quality.
In addition, the fluidity of liquid silicone can be increased by adjusting its pH value. The pH value is a measure of the acidity and alkalinity of liquid silicone, and different pH values have a certain impact on the fluidity of silicone. Some chemical reagents can change the pH value of liquid silicone to a certain extent, thereby increasing its fluidity. Taking a certain medical device company as an example, they used the method of adjusting pH value when producing medical catheters made of liquid silicone. By adding a small amount of reagents such as acetic acid or sodium hydroxide to adjust the acidity and alkalinity of liquid silicone, the flowability of silicone was successfully improved, making the production of the catheter smoother.
In summary, there are many practical methods to increase the fluidity of liquid silicone, including adjusting viscosity, controlling temperature, and adjusting pH value. These methods have wide applications in different industries and fields. By selecting and applying these methods reasonably, the flowability of liquid silicone can be effectively improved, meeting various production needs, and promoting the development of the industry.
