What is the liquid in the level ruler?
A horizontal ruler will have horizontal bubbles in which liquid flows, and the bubbles inside will also move when tilted left and right. The level ruler is used to measure the level, so what liquid is the water in the ruler?
In fact, the liquid in the level is not ordinary water, but a mixture of alcohol, glycerol, ethylene glycol, and water, which is made into a specific ratio and loaded into the level. The reason for using this liquid is because the level requires that the liquid will not freeze, has good fluidity, stability, and can emit fluorescence.
How to fill the liquid in the water level gauge
In the process of making a flat water level, how to put the liquid into the level and center the bubbles is the key to the measurement accuracy of the entire level. Next, we will introduce water to everyone
The liquid filling process of a ruler:
1. Place the body of the level ruler on the machine and dig out several holes, which will be filled with bubble containing level bubbles and used as handles.
2. Melt the plastic and inject it into an arc shaped small bottle, which serves as a level bubble. The injected small bottle is sealed at one end and has an opening at the other end.
3. The small bottles are delivered to the mechanical claws through a vibrating disc feeder. The mechanical claws grip each small bottle and rotate it with the opening facing upwards, injecting mixed liquid into each small bottle
Inject the same amount of liquid, leaving only the space required to form bubbles.
4. The mechanical claw covers the small bottle with a plastic cap, which is welded onto the small bottle using an ultrasonic welding machine to seal the liquid inside the small bottle.
5. The horizontal bubble with bubbles will be captured by a camera, and the computer will automatically detect the size and position of the bubbles to determine whether they are qualified. The small bottle will be rolled on the machine,
Heat transfer the two indicator lines onto the small bottle.
6. At this point, the small bottle needs to undergo another inspection. The small bottle that passes the inspection will enter the solid fusion system, which injects the molten plastic into the gap, forming a horizontal bubble bottom
Install the horizontal bubble with a base into the opening of the ruler body and fix it with glue.
3、 Is liquid level toxic
Non toxic.
The liquid in the level gauge is ethylene glycol, alcohol, water, and glycerol, all of which are non-toxic and harmful. Breaking the level gauge can cause the liquid to stick to the body without use
Worry, just rinse it off with clean water.
