WristbandWhat’s the use of it
One, hand strap
Anti-static wrist The electrostatic ring is a device that is worn on the wrist of the human body to discharge the accumulated electrostatic charge of the human body. It is divided into wired type and wireless type, with metal ring and elastic conductive wire mixed ring. This product belongs to one of the anti-static wrist strap buckle adjustment wired type, which can effectively protect the zero resistance parts from being disturbed by static electricity, and is used to discharge the static electricity of the human body. It consists of an anti-static elastic band, a movable snap button, a spring cord, a protective resistor and a collet. The inner layer of the elastic band is knitted with anti-static yarn, and the outer layer is knitted with ordinary yarn. The principle of the anti-static wired wrist strap is to conduct the static electricity of the human body to the ground through the wrist strap and the grounding wire. Use the wrist strap in contact with the skin and ensure that the ground wire is directly grounded for maximum effectiveness. Wearing this anti-static wrist strap, it can safely remove the static electricity generated in the human body within 0.1 seconds. The grounding wrist strap is the most basic and most commonly used anti-static equipment.
Hand strap function
1. It can be used as a high-static power source due to improper contact by personnel, resulting in instant introduction A large amount of static charge, when the ion neutralization is not completed, can effectively eliminate static electricity by providing ion neutralization (corona discharge effect) with the air water molecules outside the screw to achieve electrostatic discharge (static voltage balance). Final goal.
2. This screw can be used for potential zeroing function (just touch the screw to ground).
3. It can be used as a loop detection terminal.
Second, Sports Bands
Various charities and groups have interpreted wristbands to give a special meaning to the various colors of wristbands. You can express your attitude towards life with a wristband in a specific color, you can also use a different color to inspire your health and youth, and match it with different outfits to be the coolest person on the street.
The connotation of each color
Blue represents ‘high ambition’ – the pursuit of equality, tolerance and lofty ideals to make life more meaningful;
Green means ‘don’t make excuses’–eliminate differences, break down barriers, and everyone is responsible;
Pink means ‘unconstrained’-imagination, the world has always moved forward Motivation;
The orange color tells you to ‘come one-on-one’ – it is more courageous to challenge yourself than to challenge others;
Red advocates ‘high ambition’ – no matter how high one jumps , but also higher than the inner ambition;
Yellow declares that ‘dream is not too big’ – as long as there is a dream, everything can come true;
Purple proposes ‘there is danger, there must be organic ‘????Seize every opportunity, turn danger into danger, and the goal will not be far away from us;
Light green means ‘the brave are fearless’-full of confidence and fearlessness, this power is hidden in you and my heart. Eight colors, written with eight different positive attitudes, encourage everyone to ‘don’t underestimate yourself’ and discover your unlimited potential.
3. Metal straps
Metal wrist straps are mainly used in purification workshops. The service life depends on the life of the grounding terminal. Generally, the best anti-static products made in China are used. The metal wristband is bent 6,000 times, and imported 60,000 to 100,000 times. However, there are many problems with domestic wristbands. For example, elastic wristbands are fragile and the connection parts are not tight enough. Imported wristbands can be used for at least two years. The same is true for metal wristbands.
IV. Identification belt
s
Widely used in the medical industry, inpatients wear wristbands to facilitate doctors to check the patient’s identity, and some wristbands have A two-dimensional code recognized by mobile devices, one of the most basic applications of the two-dimensional code is to record the basic information of the patient (such as: name, age, blood type, ID number, emergency contact number, etc.), and also includes medical history, allergy history and other medical information. Help doctors to fully understand the patient’s situation. This application is especially suitable for emergency patients and the elderly. The doctor can quickly confirm the patient’s detailed information by scanning the QR code, complete the admission registration and perform first aid, which is not only efficient but also accurate. First aid buys precious time.
Some amusement parks, expositions, etc. in the form of pass tickets will also distribute wristbands with identification barcodes to visitors.
WristbandSelection Skills
1. The inner layer of the wrist part of a good anti-static wristband is made of silver wire. The more turns, the better the electrical conductivity;
2. The PU wire connected to the wrist strap is stronger than the PVC wire and has better resilience;
3. The internal material of the grounding wire is preferably copper wire;
4. The bending times of the grounding wire part and the connecting part of the wrist strap can be detected by the corresponding instrument. If there is no user of the detection instrument , it is recommended to obtain the corresponding third-party test report from the purchaser.
