licone has the open vesicular structure , large specific surface. So it can absorb many substances as a good desiccant, adsorbent and catalyst carrier. Adsorption of the silicone is mainly the physical one that can be regenerated and good for repeated use. Let the silica gel soak in the cobalt dichloride solution then get it dried and activated , will become the allochroic silica gel. It will transfer from blue to red color when absorb water. Changes in color shows the degree of water absorption and whether need the regeneration treatment. The bracelet is generally used as ornaments or jewelry, now more and more people use the bracelet to do business promotional gifts, souvenirs, gifts and so on. Currently a kind of silica gel made silicone bracelet is especially popular on the market. A silicone bracelet : 1, soft and comfortable to wear. 2 a customized LOGO is used for printing, promotional gifts, business gifts, or gifts. 3, incorporation of negative ion powder in the silicone bracelet has been reached to care for the human body,like promote blood circulation, anti fatigue and other health and body balance effect. This kind of bracelet is also called energy bracelet. et as awareness or inspirational item. It is very popular among sports players. Let us see several kinds sports bracelet. Glow in dark silicone wristband is popular for night event. But it is also good for night walk or run. A glow in dark silicone wristband can glow green or blue after absorbing strong light energy. The glow will fade gradually in about 3h and will recover absorbing light again. A mosquito repellent silicone bracelet is very useful to protect ourselves from the mosquito outdoor. It is made from high quality silicone together with lemongrass, lavender, clove and other natural plant oils. And the natural plant oils is the reason why it is mosquito resisting. Usually sport player has bigger size of wrist than most of us. So we have to choose the right size. There are 6”(150mm) for toddler, 7”(180mm) for youth, 8”(202mm) for adult and extra large of 210mm, 250mm in circumference and 1/4”(6mm), 1/2”(12mm), 3/4”(19mm), 1”(25mm) in width. We make it all together 2mm thickness. UV silicone bracelet is a good choice for out door activities or sports like Climbing, rock climbing, cliff descent, kayaking, diving, sailing and so on. A UV silicone bracelet can transfer it’s color darker under sunshine when absorbing UV light. It transfer to purple or blue normally which indicating the strength of the UV index. Wearing it on the wrist is a good way to avoid long time staying under strong sunshine. nergy under the effect of phosphor which is very small amount added and green to human. The glow will fade gradually in about 3h depending on how much light it absorbs. It is the best one for night event. Such music show, night walk and so on. The logo can be same as regular debossed, embossed or printed on the glowing wristbands. After exposure to natural light, fluorescent light, and ultraviolet light, the phosphor can store the light energy, stop the light and release it slowly in the way of fluorescence, so the light can still be seen at night or in the dark, lasting for hours to more than ten hours. The luminescent powder can be automatically lit in the dark. The main component is rare earth, which belongs to inorgpromotion giftsanic materials. The luminous powder first absorbs a variety of light and heat, converted into light energy storage, and then automatically luminescence in the dark, by absorbing all kinds of visible light to realize luminescence. The product does not contain radioactive elements, and can be used indefinitely, especially for short wave visible light, sunlight and ultraviolet light (UV light) under 450 nanometers. Accept the ability. Here is the properties of the luminous powder. 1st short excitation time, long duration of luminous and afterglow, high brightness. 2ndvery stable physical and chemical properties, strong environmental adaptability, ordinary service life. 3rd safe and reliable, energy saving, green environmental protection.4th The particles are small, and the fineness and granularity are evenly distributed. In the actual life, people make use of the long time luminescence characteristics of night light powder to make a weak light source, and have special use in the military department. This material is applied to various kinds of switch signs on the aviation instrument, clocks, windows, machines, and the handle of the door, and can also be pressed into various symbols and parts together with a variety of transparent plastic materials. Supplies (such as power switches, sockets, fishing hooks, etc.). These light-emitting components are illuminated at night, at night or by accidental blackouts, and aftepromotion giftsr lightning, and it still continues to glow, allowing people to discern the direction of the surrounding and bring convenience to work and life. The ultra-fine particles of luminous materials can be added to textiles to make the colors more colorful. Children wearing luminous textiles can reduce traffic accidents.
