The developing direction of glass thermometer industry is that mercury-free glass thermometer replacement has hydrargyrum glass thermometer.Global vitreous body
Every year at 200,000,000 about, production value (having hydrargyrum), more than 1,000,000,000 RMB, is essentially all raw in China to temperature meter market capacity
Produce.If can not produce a mercury-free glass thermometer in industry, glass thermometer industry also will disappear therewith.
Gallio liquid alloy is a kind of neogen, tasteless, non-combustible, non-explosive, not spontaneous combustion and do not have combustion-supporting property, in water
And it is all soluble in organic solvent.Its fusing point can as little as -30 DEG C even lower, about 2300 DEG C of boiling points.Gallio liquid alloy
Have extensive liquidus temperature interval, steam pressure is very low.Therefore, the gallio liquid alloy replacement for mercury conduct of environmental protection is used
The temperature sensing liquid of glass thermometer produces glass thermometer, has highly important environmental protection and commercial value.
Gallio liquid alloy substitutes hydrargyrum as the temperature sensing liquid of glass thermometer it is impossible to set using existing mercury clinical thermometer
Standby production, still has some technical barriers to need to capture.Wherein, because gallio liquid alloy is oxidizable, and in gallio liquid alloy
Containing micro gas；In addition, gallio liquid alloy can corrode most metal or alloy at high temperature, adopt in industry
Stainless steel crucible, titanium alloy crucible all can pollute to gallio liquid alloy；A variety of above, all can be to mercury-free glass thermometer
Quality impact.

In the crucible placing described gallio liquid alloy with for the heater to the heating of described gallio liquid alloy, described vacuum tank
Agitator for being stirred to described gallio liquid alloy is provided with body.
Described agitator is magneto magnetic fluid agitator.
Described magneto magnetic fluid agitator includes magneto, magnet fluid sealing and the spiral being located in vacuum tank
Stirring paddle, magneto, by means of magnet fluid sealing, stirs described gallium using magnetics principle non_contact drive propeller
Base liquid alloy carries out degasification.
