The application of touch screens is becoming more and more widespread. How much do we know about touch screens? Differentiating touch screens from technical principles can be divided into five basic categories: vector pressure sensing technology touch screens, resistive technology touch screens, capacitive technology touch screens, infrared technology touch screens, and surface acoustic wave technology touch screens. Among them, the vector pressure sensing technology touch screen has withdrawn from history; the infrared technology touch screen is cheap, but its frame is fragile, prone to light interference, and distortion in the case of curved surfaces; the capacitive technology touch screen has a reasonable design concept, but its image distortion problem is difficult to obtain Fundamental solution; resistive technology touch screen is accurate in positioning, but its price is quite high, and it is afraid of being scratched easily; surface acoustic wave touch screen solves various de...

Inlay is a special term for the RFID industry. It refers to a pre-laminated product made of multiple layers of PVC or other materials containing chips and coils. Different types of RFID tags can be made through different forms of packaging. rfid Inlay can be understood as a semi-finished product that is not encapsulated by the RFID tag. Inlay is divided into Dry Inlay and WetInlay.Dry Inlay does not contain adhesive, and the structure is antenna + chip + chip packaging; Wet Inlay contains adhesive and can be directly attached to the object, and the structure is antenna + chip + chip packaging + surface paper + bottom paper.

Water treatment equipment will take care of harmful substances for you Selenium is one of the essential elements of the human body, but selenium compounds are toxic to humans and animals, ( water treatment equipment ) has obvious accumulation in the body, which can cause acute and chronic poisoning. In addition to geological factors, selenium in water mainly comes from industrial wastewater pollution. Excessive intake of selenium by humans and animals can cause selenium poisoning. The clinical manifestations of human endemic selenium poisoning are loss of appetite, weakness of limbs, itchy scalp cancer, mangy skin, patchy teeth, hair and nail loss, etc. The selenium poisoning of livestock is manifested as loss of appetite, hair loss, hoof removal, jaundice, anemia, etc. After eating high-selenium plants, it can be fatal in a short time. Endemic selenium poisoning is mostly due to the high selenium content in the soil, resulting in excessive selenium accumulation in local food crops, ve...

Water treatment equipment test method (1) Test substance. The test substance should be dissolved or suspended in a suitable medium. It is recommended that water be the first choice, followed by vegetable oil (such as corn oil), and again consider using other mediums (such as carboxymethyl cellulose, gelatin, starch, etc.). For non-aqueous media, its toxicological characteristics should be understood, and whether its toxicity should be determined before the test. The maximum volume of the liquid for oral administration depends on the size of the experimental animal. The liquid dose given to rodents is generally 1~2ml/100g. By adjusting the concentration of the test substance solution, the oral dose of each dose group was consistent. (2) Experimental animals and breeding environment. Healthy adult mice or rats are preferred, and other sensitive animals can also be used. The small pickup weighs 18~22g, and the rat body~220go animal should be built in the laboratory animal room environmen...

Usually when we talk about touch screen, we will talk about two kinds of it, one is resistive touch screen, the other one is capacitive touch screen. Before figuring out what a touch screen display is, let's first understand the basic principles of touch screen display product operation. Simply put, display products are to solve the relationship between electricity and optics. After strict design and manufacturing, the product is controlled by the embedded integrated chip to control the current operation, and the positive and negative electrodes are connected. The precision components inside the product are drilled. Then, light is generated and then the screen appears. And how is the touch function implemented? The answer is the same: the two conductive layers contact each other, the current at the contact point changes, and the corresponding function is executed.To control the change of the display screen through the touch principle, this is the basic principle of the operation o...

Electric door opener Electric door opener s are also called automatic door opener releases, electric releases, etc. It is a mechanism that realizes the automatic closing of the door leaf through electric control. Electric door openers are different from hydraulic fire door openers. They combine the functions of an electromagnetic release and non-positioning door openers into one. There are solenoid valves and strong springs inside. The springs are compressed when the door is pushed and locked by the solenoid valves to keep the door normally open. When power is supplied, the solenoid valve is released and closed by the rebound impact of the spring, without buffer function. It was first applied to normally open fire doors. Later, due to the fire department's belief that power transmission and closing doors did not comply with fire protection regulations, they were not promoted and applied in the fire door market. Hydraulic automatic door openers are still used in the fire door marke...
