Energy Saving in the Field: How to Use Warmers to Keep Warm Without Additional Resources
The first primitive means of heating were not like today's. Hot stones were wrapped in special bags and used to ensure comfortable outdoor recreation. The use of new technologies made it possible to find out what a chemical heating pad is. Tourist products help to maintain and preserve comfort for a long time without using another heat source.
Modern heating devices:
- do not harm health;
- effective;
- easy to use;
- reliable.
A lightweight and disposable chemical heating pad, which is presented on the website showerpack.com.ua, is suitable for hiking, fishing, winter sports and hunting. It is easy to select products, taking into account the main characteristics:
- activation type;
- safety - no harmful components in the composition;
- maintained temperature;
- impact on the environment - harmless disposal;
- weight and size;
- warm-up time depends on the size and type of the product.
The company's managers are ready to help you choose the best product. There are several options for contacting them, listed on the official website of the Shower Pack store.
Chemical heating pad: what is it?
Heat maintenance patches include chemical reagents placed in special bags. After entering the air, the contents are activated and generate heat. Products differ in characteristics and how the chemical heating pad looks. Manufacturers, when developing portable heaters, take into account the thermal insulation and heat exchange of certain parts of the body. Therefore, devices are produced with various temperature data indicated on the packaging.
Advantages of disposable heating devices:
- the best value for money;
- easy start;
- no need for additional energy sources;
- portability - light weight and compactness are perfect for conquering mountain peaks.
The salt self-heating patch contains chemical reagents - sodium or calcium chloride. The operating time is 8-10 hours.
All outdoor enthusiasts who are familiar with a convenient disposable chemical heating pad know that this device is easy to dispose of. And its activation time takes up to 10 minutes. Reusable products have a renewable function. They are easy to use several times. They are economical and environmentally friendly.
How do chemical heating pads work?
The heating agent starts working after squeezing or shaking. The reagents mix, causing the interaction of air, salt and water. And the iron grains begin to give off heat. The processes inside the product are activated without the use of an external energy source, such as a battery or electricity. It is easy for everyone to understand how to heat up a chemical heating pad.
The patches contain natural components:
- activated carbon as a catalyst and heat accumulator;
- vermiculite as a clay mineral;
- salt catalyst;
- purified water to speed up the chemical reaction;
- iron powder, which reacts with oxygen and releases heat to the outer shell.
The substances inside the chemical heating pad are mixed in certain proportions and packed in soft fleece. As soon as the integrity of the material is broken, air gets inside and chemical oxidation begins, generating thermal energy. The volume of incoming oxygen is limited by dense fleece.
How to restore a chemical heating pad?
The description of reusable salt products indicates how to restore a chemical heating pad. The product has a saturated saline solution that releases heat when crystallized. It heats up instantly and maintains comfort for a long time.
After the initial use of the salt patch, it should be placed in a cloth bag and lowered into boiling water for 5-20 minutes. This is the time for the substance to transition from a crystalline state to a liquid, which will allow it to be reused.
Understanding how a chemical heating pad works will protect you from unpleasant consequences. It is important to remember the warnings:
- do not fold the product when the contents are in the form of crystals - will cause the package to rupture;
- before boiling, warm the heating pad to room temperature with a towel;
- avoid contact with sharp objects when removing the patch from the water.
If the patch does not fit completely into a container with boiling water, it is worth dissolving one side and then the other. It is very important to understand how a chemical heating pad works. It can crystallize on its own if it is strongly cooled or punctured. If snowflakes form after activation, this will not affect the quality of the heating padroarer.
