Q:What's the difference between stainless steel wire and steel wire?
General zinc coating of the cold rolled plate on the basis of annealing, in the plating and stainless steel annealing, it is estimated that the material will change, so the plating is more bad, in theory, more likely to rust
Q:What are the basic characteristics of wire resistance strain gages?
The resistance value of the components size and temperature, material, length and cross-sectional area, the measure of the size of the resistance is affected by temperature is the temperature coefficient of resistance value, which is defined as the percentage change in temperature rise every 1 degrees. The main physical characteristic of resistance is that the electric energy is heat, and it is also a component of energy dissipation. Resistance usually acts as a divider and shunt in a circuit. For signals, AC and DC signals can be passed through resistors.
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?
Therefore, the removal of metal surface impurities and removal of metal surface oxides, the two are different.
Q:Are two wires of the same material but different in thickness and length? Are their young's modulus of elasticity the same?
identicalThe young's modulus depends only on the physical properties of the material itself, irrespective of the thickness or length of the material.Young's modulus characterizing the physical resistance of solid materials to deformation, and the physical quantities characterizing the properties of the material. The young's modulus reflects the rigidity of the material, and the greater the young's modulus, the less deformation it is prone to.I hope I can help you.
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:What silk is fine as hair, soft as wool, strong as steel?
Characteristics of molybdenum wire:Ultra high tensile strength;It has high surface finish, good stability and high cutting accuracy;Elongation rate is small, tight silk is small;The winding rate is large, the wire diameter is uniform, it is difficult to break the wire, and the service life is long;Increase the high frequency power and improve the rough machining efficiency;The accurate measurement, vacuum packaging, prevent oxidation mildew, can be stored for a long time.Remember, the smallest one is only half a millimeter. It's very, very thin. One second you can cut down 1 trees. Of course, it depends on whether the equipment supports it!
Q:What fabric is the wire made of? What are the advantages and disadvantages?...
Metal wire fabric is the most popular natural memory folds and antistatic functional fabric defects: fine metal fiber, easy to disconnect, do not scrub, not dry after washing and drying. Do not rub the fabric, with a long time shielding value will decline, washing and folding is very easy to destroy its effect. Washing should take into account its heat resistance, so it can not use too high water temperature, can not use bleach containing detergent or washing powder for washing, so as not to cause fading.
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
