Q:What's the difference between stainless steel wire and steel wire?
The stainless steel spring wire is usually hard, and it is cold drawn with larger wire diameter difference. Stainless steel bright wire is usually medium hard, it is normal cold drawing and cold drawing. Light drawing of stainless steel is usually in soft medium, which is cold drawing with smaller line diameter difference. The stainless steel wire is usually soft, which is annealed by hydrogen pipe after drawing, and the product has a roof shape after annealing.
Q:What are the basic characteristics of wire resistance strain gages?
Resistors (Resistor) are commonly referred to as resistors in everyday life. It is a current limiting element. After the resistance is connected to the circuit, the resistance value of the resistor is fixed, usually two pins, which can limit the current size of the branch through it.
Q:Will you please remove any of the wires? The edge of the body, which is made of wire or what? Is it copper or iron?
Residential electrical wiring generally uses only one layer of plastic insulated copper core wire, which is usually worn in plastic pipes or steel tubes, concealed in the wall, in order to avoid mechanical damage. Conductor part of the conductor in the structure of solid and twisted two kinds, and its components are pure metal, alloy, coating and enameled wire. (referring to the Baidu encyclopedia wire structure) metals cannot ignite, and copper has a melting point of more than 1000 degrees! No electricity, no electricity, of course. Does not rub with wood to produce electricity or sparks.
Q:What method can be used to detect residual impurities and metal particles on the wire surface?
Remove the metal surface oxide, refers to the removal of the metal itself has been oxidized surface, such as: rust, skin and other materials that originally belong to the material itself.
Q:Are two wires of the same material but different in thickness and length? Are their young's modulus of elasticity the same?
According to Hooke's law, in the elastic limit of an object, the stress is proportional to the strain, and the coefficient of proportionality is called the young's modulus (Y). Express as a formula:Y= (F - L) / (S - L)Y is numerically equal to the stress produced by unit strain. Its units are the same as those of the force. Young's modulus is the property of a material, independent of force and shape of an object.Young's modulus (Young's, modulus) is a noun in mechanics of materials. When the elastic material is subjected to the positive stress, it will produce a positive strain, defined as the ratio of the forward stress to the positive strain. The formula is denoted as E = sigma / epsilonAmong them, E represents Young's modulus, sigma represents positive stress, and epsilon represents positive strain.Young's modulus is large, indicating that in compression or tensile material, the deformation of the material is small.
Q:Why is the current limiting circuit used to measure the resistance of wire by voltammetry?
Because the resistance of wire is very small, almost zero. According to the current, equal to the voltage divided by the resistor, it is known that the resistance is almost an hour and the current is close to infinity. This will burn out the power supply, so the current limiting method must be used
Q:What's the metal wire fabric?Such as title
Metal wire fabric not only has metal luster, and wear to trim visible, noble, gorgeous, and the fabric has the function of conductive shielding, which is widely used in scientific research, military and medical industries such as electronics, high-tech, high added value.Currently do men and women's windbreaker, jacket, jacket and jacket.
Q:How can you make the fabric with silk fabric wrinkle free after washing?
Used in clothes last rinse, after use without water; (i.e. when the clothes have used laundry detergent and rinse clean, to the water softener is dissolved, and then soak the clothes can no longer need cleaning and water
Q:What silk is fine as hair, soft as wool, strong as steel?
Steel wire can be processed to fine hair, of course, such as steel wire, but it can not be soft as wool (of course, very thin strands of steel are also very soft).
Q:What is the difference between carbon fiber and wire heating?
The biggest characteristic of carbon fiber heating is that the electromagnetic radiation is very small. It is smaller than the electromagnetic shielding of the wire, and is harmless to the human body
