Abstract
The invention discloses thermometer temperature sensing liquid containing gallium alloy. The temperature sensing liquid is prepared by mixing and heating 45-64.5 parts by weight of gallium, 20-32 parts by weight of indium; 9-15 parts by weight of tin; 9-15 parts by weight of zinc; 0.005-0.01 part by weight of germanium and 0.002-0.01 part by weight of copper. The temperature sensing liquid is non-toxic and non-volatile, thereby not causing harm to human health. The temperature sensing liquid can be used as a measuring medium of a glass thermometer for measuring human body temperature or animal body temperature.
Description
Technical field
The present invention relates to a kind of glass-stem thermometer with measuring media.Specifically, be the glass-stem thermometer temperature sensing liquid that is used to measure human body temperature or animal heat.
Background technology
At present, being used to measure the clinical thermometer of human body temperature or animal heat, mostly is glass-stem thermometer.This glass-stem thermometer is formed with the hollow glass rod with the temperature-sensitive head that this hollow glass clavate becomes one.Interior canned temperature sensing liquid---the mercury that has of temperature-sensitive head wherein.Because commercially available mercury does not reach production requirement, therefore need it is carried out purification processes.And in the purification processes process, can make unavoidably outside it is exposed to.Again because mercury is toxic substance and can volatilization under the temperature more than 17 ℃, so, no matter be in the production process of glass-stem thermometer, when still in its use, damaging, all can work the mischief to HUMAN HEALTH.For this reason, the someone has proposed a kind of thermometer temperature sensing liquid without mercury, in this temperature sensing liquid, owing to there is not mercury, has therefore avoided traditional more caused problems of mercury.In the applicant application and the patent of obtaining the authorization, put down in writing such technical scheme, wherein: gallium 45-64.5 part, indium 20-32 part, tin 9-15 part, zinc 9-15 part.Use through actual, find that its proportion of this metal alloy is lighter than mercury, use and in thermometer, can cause temperature to be difficult to restore, that is, after using, be difficult to the temperature of thermometer is reduced below the normal body temperature that returns back to the people again; This alloy can solidify and be lower than-5 ℃ being liquid more than-5 ℃ in addition,
Summary of the invention
The object of the present invention is to provide a kind of thermometer temperature sensing liquid that contains gallium alloy, this temperature sensing liquid, nontoxic and can not volatilize, can not work the mischief to HUMAN HEALTH.
Above-mentioned purpose of the present invention is realized by following technical solution:
The thermometer temperature sensing liquid that contains gallium alloy of the present invention is to make through mixing, heating with the raw material of following parts by weight;
Gallium 45-64.5; Indium 20-32; Tin 9-15; Zinc 9-15; Germanium 0.005-0.01; Copper 0.002-0.01; Wherein: the purity of gallium, indium, tin, zinc, copper and germanium is respectively greater than 99.99%, 99.99%, 99.5%, 99.5%, 99.5%.
During preparation, earlier described raw material is all put into the stainless steel vessel of sealing, and stainless steel vessel is vacuumized, under vacuum condition, described raw material is heated to 250-650 ℃, make described raw material fusing; Allow its naturally cooling then, promptly can be made into the thermometer temperature sensing liquid that contains gallium alloy of the present invention.
Adopt such scheme, have the following advantages:
Because the present invention adopts the gallium alloy of being made by gallium, indium, tin and zinc to substitute the temperature sensing liquid of traditional mercury as glass-stem thermometer, and gallium alloy is nontoxic, can not volatilize, therefore, no matter be in the production process of glass-stem thermometer, when still in its use, damaging, can not work the mischief to HUMAN HEALTH.Especially after in described temperature sensing liquid, having added germanium and copper, make the temperature application range of this temperature sensing liquid expand-15 ℃-1200 ℃ to from original-10 ℃-620 ℃, therefore can be applicable in all temps meter; Simultaneously, in original temperature sensing liquid, added germanium and copper after, make temperature sensing liquid of the present invention proportion can near or reach the proportion of mercury, in use, medical personnel or patient and family can restore the temperature sensing liquid in the thermometer easily, in order to use next time.
