Problems solved by technology

[0003] But mercury is a poisonous substance. When the thermometer is broken, the mercury in it will flow outside and generate mercury vapor, which will cause serious damage to the body through breathing. Therefore, a thermometer that replaces the temperature-sensitive solution has appeared, but this kind The high linear expansion coefficient of the thermometer may cause the body of the thermometer to burst. At the same time, the high linear expansion coefficient will also increase the original length of the thermometer, which is inconvenient to use and difficult to install.

Abstract

The invention discloses a thermometer and a preparation method of the thermometer. The thermometer is composed of, by weight, 100 parts to 120 parts of gallium, 55 parts to 70 parts of indium, 18 parts to 24 parts of tin and 5 pars to 8 parts of zinc. The method includes the following steps that first, 100 parts of gallium and 55 parts of indium are taken and purified, and the purity is made to be larger than 99%; second, the gallium and the indium purified in the first step are mixed with 18 parts of tin and 5 parts of zinc, and a mixture is stirred; third, the mixed solution is heated at the temperature of 600 DEG C, and the heating time lasts for three hours; fourth, the mixed solution in the third step is cooled, and after the temperature of the solution is lowered to below 100 DEG C, a temperature sensing solution can be obtained; according to the thermometer and the preparation method of the thermometer, due to the temperature sensing solution, it is avoided that the interior of the thermometer bursts, and meanwhile the length of the thermometer will not be changed so that the thermometer can be convenient to use and place.

Description

technical field [0001] The invention relates to a thermometer and a preparation method thereof. Background technique [0002] In current medical thermometers, the temperature-sensitive solution contained in the temperature-sensitive bubble is mercury. [0003] But mercury is a poisonous substance. When the thermometer is broken, the mercury in it will flow outside and generate mercury vapor, which will cause serious damage to the body through breathing. Therefore, a thermometer that replaces the temperature-sensitive solution has appeared, but this kind The high linear expansion coefficient of the thermometer may cause the body of the thermometer to burst. At the same time, an excessively high linear expansion coefficient will also increase the original length of the thermometer, which is inconvenient to use and difficult to install. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a thermometer that is easy to u...
