In the high temperature and high humidity environment, it
is not conducive to the storage of parts and military units, and the damage
caused by moisture, mold and metal oxidation is occurring at any time, and
often wait until the time of discovery, the machines may have failure, which is
not only time-consuming and expensive for subsequent repair and maintenance,
but also seriously affects the working efficiency and product quality. (The
harm of damp to military products: non-metallic products will mainly occur
mildew and moisture, metal products will have corrosion and other corrosion
phenomenon), today let‘s know more about the damages to 
military equipment
caused by dampness.
Effects of Moisture on “Military Products”
At present, the military ammunition depot is mainly ground
storage, after entering the summer, the storage environment will be greatly
changed, high temperature and high humidity environment is not conducive to the
safe storage of ammunition. Can cause the following hazards:
1.Metal is the element that forms the components of the
munition
The effect of humidity on them is mainly to promote its
rust. The greater the humidity in the warehouse, the more serious the
electrochemical rust. The corrosion of ammunition will not only shorten its
storage life, when the corrosion is heavy, the shell will cause the difficulty
of retarding the shell during the shooting; the warhead will affect the
shooting accuracy; the fuze parts will affect the normal operation of the fuze,
resulting in inaccurate effect, and even promote the insurance to lead to serious
accidents.
2.Effect of humidity on Gunpowder
When the humidity is too high, it will absorb moisture and
increase the moisture content of gunpowder. It will appear that it is not easy
to ignite, the burning rate drops and the combustion in the chamber is not
complete. At the same time, it will accelerate the hydrolysis, accelerate the
deterioration, and greatly shorten the storage life. When the humidity is too
small, the moisture in the gunpowder will be reduced by evaporation, and the
burning speed of the gunpowder will be accelerated, and the chamber pressure
and initial speed of the firing will rise, which will affect the shooting
accuracy and easily produce far bombs.
In addition to mainly metal and gunpowder, ammunition
contains wood, paper, cloth, plastic parts, protective coatings and sealed
mannequins, which are affected by humidity and also deteriorate, directly or
indirectly altering the properties of the ammunition, affecting its use and
long-term storage.
3.Effects of Moisture on “Laboratory Products”
Test paper, PH measuring machine, sample, test drug, powder
material, temperature and humidity measuring instrument, electronic measuring
instrument, metal material… and other instruments, the relative person should
do a good job of moisture-proof, dust-proof measures. In particular, some
long-term instruments (such as water quality tester, ion tester, electronic
titrator, etc.), because the temperature after the start-up can allow the
humidity attached to the surface of the parts to evaporate, and these
infrequent operating instruments, moisture can easily damage the internal parts
of the instrument to produce mildew, oxidation, rust, poor signal transmission
and other failure or damage. In addition, the adhesion of dust will also affect
the heat dissipation of the equipment, let it run too high temperature and
cause the danger of short circuit, so the equipment need to be stored in a wet,
warm, low dust environment, and have a stable and correct supply of power, so
that even if it is not turned on. Thus, the dry environment in which the
components and instruments of the Institute of Military Industrialization Units
are located is an essential external condition.
