Weapon sweating
In cold weather, when we take the weapon from the outside into the warm room, the "sweat" will appear on the weapon for a while. Where does this "sweat" come from? Did you bring it in outside? no This is caused by the temperature difference between indoor and outdoor and the moisture in the air.
We know that in the clear and windless night or early morning, there are drops of water condensed on the plants and leaves. This is because the ground object absorbs a lot of heat under the sunshine during the day. At night, the surface of the ground object emits heat, and the water vapor in the air condenses into drops of water on the surface of the ground object. Similarly, when a low-temperature weapon is suddenly taken into a warm room, the weapon surface absorbs heat, the moisture in the air contacts the cold weapon, and the weapon suddenly cools down, and the moisture will condense into "sweat" on the weapon surface. This phenomenon also occurs in summer when the temperature difference between inside and outside is large.
In case of "sweating" of weapons, wipe off the "sweat" in time. Premature, "sweat" did not end; Too late, "sweat" may seep into the weapon and rust the weapon. It's best to wipe the weapon as soon as the "sweat" comes out after 10 or 20 minutes.
