Description
A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Components – capacitors, resistors or active devices – are generally soldered on the PCB.
Description
Power cords are detachable means of supplying electricity from a main power source to electrical equipment or appliances. Power cords consist of a flexible cord with electrical plugs at each end, one male and one female. The female plug connects to the appliance or electrical equipment. The male plug connects the electrical receptacle, electrical outlet or power supply.
Description
Industrial Plugs and Sockets are used for power connection in industrial applications. Industrial plugs and sockets are used for power connection in industrial applications or other situations rated at higher voltages and currents than household plugs and sockets. They are generally used in polyphase systems, with high currents, or when protection from environmental hazards is required. Industrial outlets may have weatherproof covers, waterproofing sleeves, or may be interlocked with a switch to prevent accidental disconnection of an energized plug.
Description
Zinc oxide, with its unique physical and chemical properties, such as high chemical stability, high electrochemical coupling coefficient, broad range of radiation absorption and high photostability, is a multifunctional material. With the excellent properties, zinc oxide plays an important role in a very wide range of applications varying from tires to ceramics, from pharmaceuticals to agriculture, and from paints to chemicals. Zinc oxide can be classified into three types according to the production technique: indirect process, direct process and wet chemical process. Indirect process also called French process, and direct process also called America process.
Description
 This mixture is then chopped up and heated to break it down further into strands of cellulose called pulp or slurry. It is then strained through screens which remove any glue or plastic that may still be in the mixture. Finally it is cleaned, de-inked, bleached, mixed with water and then it can be made into new recycled paper.
