What is a vacuum flask glass refill&thermos flask

Vacuum flask is made up of the bladder, the shell and the additional parts.

1. Vacuum flask by both inside and outside the glass bottle.

Bottle in connection between the two as a body, two into a vacuum bottle wall clearance in order to weaken the heat convection, the glass bottle wall surface bright silver plating film reflection infrared thermal radiation. Bottle in high temperature, content of heat energy is not outward radiation; Outside the bottle when in low temperature, heat radiation from the bottle, vacuum flask and effectively control the conduction, convection and radiation heat transfer.

There is have three processes that cause heat transfer .

Conduction

Radiation -Another side effect of atomic motion is vibration, and vibration leads to the unexpected phenomenon of infrared radiation.

Convection - Convection is a property of liquids and gases. It occurs because when a liquid or gas gets hot, it tends to rise above the rest of the body of liquid or gas .

2. Shell

The shell has a certain strength, in order to protect the tank and increase the decorative effect. Shell is made of tin sheet steel, brass, aluminum alloy, stainless steel and plastic, etc.

3. Additional parts

According to the water with different parts. Ordinary thermos to portable shell and handle, pour bottles of water, need to be equipped with cork, such as a cork, soft rubber expansion plug, ball cavity water control plastic plug, screw thread out of the cistern gyration plastic plug, etc.

It is made with two layers of glass bottles, while vacuum bottle, cut off from the air to heat transfer; Second, bottle wall coated with mercury, like a mirror reflects light, can put the heat radiation reflected back to the bottle; cover bottle cork, prevents the heat from the bottle slipped out, if used to hold water, also became a thermos.

How to test insulation quality of the vacuum flask?

• Check the inside (that is, the suction mouth) is intact, if there is a break between layers is damaged inside the vacuum, lost heat preservation ability.

• Look inside presence of blowout trace.

• See if bottle is round. If you don't round bottle, bottle stopper can't seal, will reduce the heat preservation ability.

•Fill it with boiling water and cap it.

•Measure its temperature with a thermometer every hour or two and see what the temperature graph looks like
