Description
Technical field
The utility model relates to Physical Chemistry Experiment instrument field, in particular to a kind of combustion heat experiment material containing group attaches together
It sets.
Background technique
The heat released when Determination of Combustion Heat experiment, i.e. measurement 1mol pure material completely burned is College Physics chemistry
The important means of one of important content in experiment and scientific research and industry measurement, whole experiment process to experimental data and
The precision and accuracy requirement of measurement result are higher.
In teaching Process of experiment, the measurement to substance combustion heat is usually to use Oxygen Bomb Combustion calorimetry method, i.e.,
Test substance (predominantly benzoic acid or naphthalene etc.) is suppressed into sample in the form of sheets, is put into oxygen bomb crucible, then by the silk that ignites
Middle section spire is tightly attached to sample surfaces, and both ends are fixed on two electrodes, screws oxygen bomb lid, is with two electrode of universal meter inspection
No access；If access, then oxygen bomb is placed into Environmental Incubator formula Oxygen bomb inner cylinder by oxygen inflatable gas, measures sample
Heat caused by burning.It is often difficult although this method can be measured with the combustion heat of the organic matters such as para Toluic Acid, naphthalene
To meet the experimentation to the high request of experimental data and measurement result precision and accuracy, so that there are experiment success rates
Low, experimental period is long and the various problems such as measured data of experiment precision cannot be guaranteed.
In leading to a variety of causes that leads to the problem of of Determination of Combustion Heat experiment, the silk that ignites contacted with stainless steel crucible cause it is short
The case where road is one of the most common situation, and the common silk that causes to ignite is contacted with stainless steel crucible mainly includes following
Several: the first, common crucible is deeper stainless steel crucible, and the density of combustible substance such as benzoic acid, naphthalene is larger, pressure
Print after system is relatively thin, and the silk that needs to ignite is put into stainless steel crucible bottom just and can guarantee middle screw spool fever section and sample
Intimate surface contact, but the overhang that ignites at this time is easy to contact with stainless steel crucible, especially in oxygen bomb lid and oxygen bomb
During tightening, moving, fill deoxygenation gas, be placed in the sequence of operations such as bucket in calorimeter, the overhang that ignites is easy body
It is subjected to displacement and contacts with sidewall of crucible so as to cause short circuit；Second, during the experiment, in order to which a depending portion of igniting will be avoided
Divide without impinging on stainless steel crucible, is stretched, is bent commonly using auxiliary tool (such as tweezers), but due to stainless steel earthenware
Crucible is small, operating space limitation, it is easy to cause silk kink of igniting, so as to cause itself short circuit, or ignite a Local Damaged, lead
It causes it to blow in advance at impaired place and cannot ignite；The third, because the fixed silk that ignites on the electrode hardness and quality compared with
It is small, then would generally blow displacement because of the silk that will ignite that is filled with of high pressure oxygen when being oxygenated, and then encounter stainless steel crucible or
Electrode causes short circuit, and the current distributing by the silk that ignites can be caused after short circuit, and the silk that ignites does not have the electric current of short-circuiting percentage is bigger can fire
It burns, and the electric current of short-circuiting percentage becomes smaller to burn because of shunting.
