Description

Technical Field

[0001] The utility model relates to a chlorinated paraffin density detection device, belonging to the field of chlorinated paraffin density detection equipment. Background Art

[0002] Chlorinated paraffin is an organic substance widely used in rubber, leather, cable and other fields. It is mainly divided into three products according to the different chlorine content. It has good flame retardant and insulating properties. The density of chlorinated paraffin is closely related to its performance. When testing the density of chlorinated paraffin, it is necessary to inject the chlorinated paraffin into a measuring cylinder, and then expel the bubbles in the chlorinated paraffin in the measuring cylinder by stirring or shaking, and then put the density meter into the chlorinated paraffin. The density meter cannot contact the side wall of the measuring cylinder, and read the value of the density meter.

[0003] In the prior art, ultrasonic waves are used to vibrate the chlorinated paraffin solution inside the container, and bubbles in the liquid float upward to the top surface of the solution due to the vibration, and the air inside the container is extracted by a vacuum pump to accelerate the dissipation of the bubbles. However, the vacuum pump needs to work for a period of time to ensure that the air inside the glass container is thin and reaches a defoaming state. The floating bubbles cannot be directly physically broken and defoamed, which reduces the efficiency of chlorinated paraffin density detection.

[0004] In summary, the utility model therefore provides a chlorinated paraffin density detection device to solve the above-mentioned problems. Utility Model Content
