Types of temperature sensitive patch labels
Reversible type: The temperature component changes color but returns to its original color after cooling. It can be reused continuously.
Irreversible type: The temperature component changes color but does not return to its original color after cooling. It cannot be reused.
Temperature-sensitive patches come in various styles, such as square with a circular interior, square with a square interior, etc. The sizes range from large ones that are 10cm x 10cm and can be identified with the naked eye from 10 to 20 meters away, to small ones that are 5mm x 5mm specifically for use on tiny electronic components. Due to their diverse types, wide applications, and low cost, they can meet the needs of most users.
Usage of temperature sensitive patch labels
When it is necessary to monitor the temperatures of multiple heat-generating points and issue warnings when the temperature reaches a predetermined value, but staff cannot continuously monitor them, several challenges arise: the heat sources may be located outdoors, in constant motion, or in dirty and damp environments; they may be high-voltage and inaccessible unless the power is cut off; they may be very small, densely arranged in confined spaces, and obstructed by barriers; they may be items that cannot withstand high temperatures, requiring prevention of degradation during transport; or traditional temperature measurement equipment may be unable to measure or have significant measurement errors due to weather conditions.
The forehead temperature patch is also a type of temperature-sensitive patch. By attaching it to the user's forehead and observing the color change on the patch after a few seconds, one can determine the user's body temperature and whether they have a fever.
Due to its lightweight, convenient, portable, and reusable nature, the forehead temperature patch has been widely used by many public agencies, government departments, and school institutions since 2010 as an effective measure to prevent the spread of new influenza pandemics and to encourage the public to take charge of their own health management.
Color changing temperature sensitive patch
The color-changing temperature-sensitive patch is a high-tech product based on the principle of thermally sensitive materials, which can change color with changes in ambient temperature, thereby intuitively displaying the temperature status. Its main characteristics include intuitiveness, diversity, convenience, and safety. In the medical field, color-changing temperature-sensitive patches are often used as fever-reducing patches to help monitor changes in patients' body temperature, particularly suitable for the process of physical cooling in children. At the same time, in the industrial field, they are also widely used to monitor the temperatures of electrical equipment and mechanical devices, preventing damage or safety accidents caused by overheating.
When using color-changing temperature-sensitive patches, it is necessary to ensure that the application site is smooth, clean, and dry to guarantee a good adhesion effect. Additionally, attention should be paid to the product's expiration date, and the usage methods and precautions in the product manual should be followed to ensure safe use.
Temperature sensitive color changing medical antipyretic patch
The temperature-sensitive color-changing medical cooling patch is a hydrogel patch made from polymer materials, water, natural plant extracts, etc. It has good biocompatibility and is characterized by a cool and comfortable sensation, rapid cooling, and safe use. It is the preferred product for physical cooling in children. To use, remove the protective film and apply the gel side directly to the area needing cooling. Gently press it to adhere flatly to the skin. Users can move freely while wearing it, and it can be reapplied repeatedly without affecting daily life, making it convenient and safe.
The temperature-sensitive color-changing medical cooling patch consists of a non-woven backing layer, a polymer gel layer, and a release liner. The polymer gel layer contains menthol, parabens, water, polymer substances, glycerin, etc. This product utilizes the large amount of water and volatile components contained in the polymer gel for diffusion, transferring to the skin and taking away heat through water evaporation, thereby achieving the therapeutic purpose of fever reduction and cooling.
Color changing principle of temperature sensitive color changing stickers
Temperature-sensitive color-changing stickers are a type of office supply material made using thermochromic technology. These stickers come in equal-sized square or circular shapes, and their color changes depending on the surface temperature of the object they are attached to. Temperature-sensitive color-changing stickers have a wide range of applications in daily life, such as monitoring bathroom temperature, controlling indoor temperature, and adjusting hot water bottle temperature.
The color-changing principle of temperature-sensitive color-changing stickers relies on the thermochromic properties of thermally sensitive materials. Thermally sensitive materials are materials that can respond significantly to temperature changes. When the temperature rises or falls, the color of the thermally sensitive material changes. The thermally sensitive materials used in temperature-sensitive color-changing stickers exhibit thermochromic properties within a certain temperature range, meaning that the color change only occurs when the surface temperature of the material falls within this range.
