We wear gloves and keep our hands warm when it is cold. In the cold winter, I believe that everyone has encountered such a problem: as long as the weather is cold, when you play mobile phones or play the tablet, you don't want to stick your hands out, otherwise your hands will be frozen cold and very uncomfortable. And if you put on the gloves, the screen will be completely unresponsive when you touch the screen, which is very distressing. The emergence of touch-screen gloves has largely solved this problem for us. So, what is the principle of touch screen gloves? What is the principle of touch screen gloves? The following is an introduction:       First of all, to know how touch-screen gloves work, you need to know how the touch screen works. The touch screens on mobile phones and tablets are basically capacitive screens, which work based on the induced current of the human body. The capacitive screen is a four-layer composite glass screen coated with a layer of chemically coated ITO on the innermost side of the screen and on the middle interlayer, with a thin layer of alumina glass as the protective layer on the outermost layer. And those ITO coatings are the important working faces of the entire capacitive screen. They draw four electrodes from the four corners of the screen to ensure a good working environment for the shielding layer.       When we touch the capacitive screen with our fingers, a coupling capacitor is formed between the finger and the ITO working surface due to the electric field in the human body. On the working surface, due to the high frequency signal, a small current will be absorbed by the finger on the working surface. The current flows from the four corners of the screen, respectively, and the current flowing through the four corners is proportional to the distance between the fingers and the four corners. The specific location where the finger touches. To put it bluntly, the finger touches the screen and generates an induced current that causes the capacitive screen to work. The principle of touch screen gloves       The reason why ordinary gloves can't make the screen work is that the ordinary gloves are made of thick insulating material, so that when the finger touches the screen, the distance between the finger and the ITO coating is too far apart to form a capacitor. Causes the screen to not work. In the case of touch-screen gloves, it uses conductive materials (such as metal-containing fabric fibers) in the fingers, so that an effective capacitance can be formed between the fingertips and the screen, so that the charge and current can be transmitted, and the screen is natural. It will work fine.       Through the above introduction, everyone knows what is the principle of touch screen gloves? Protect your hands in winter!
Caulking guns, also called caulk or cartridge guns, dispense a controlled flow of products such as caulk, sealants, and adhesives from a tube or cartridge.
A Manual Caulking Gun consists of a frame which holds the tube, a trigger, and a rod which moves forward when the trigger is depressed, dispensing the product.
Manual caulking guns have a thrust ratio; the higher the thrust ratio, the easier it is to dispense the caulk, sealant, or adhesive. Air-powered or pneumatic caulking guns also have a frame and a trigger, but are used with an air pressure regulator that pushes the product from the tube using air pressure instead of a rod.
