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?
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?
General electric wire wire is copper, copper. High temperature is not enough to ignite it lighter. Generally, the electricity is neutral and will not produce electricity. Friction with wood will not produce electricity or sparks, but the temperature will rise
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?
Under normal circumstances (to meet the safety conditions), because the current limiting circuit energy consumption is small, the connection is simple, therefore, priority is given to the current limiting method
Q:What's the metal wire fabric?Such as title
Because the implant metal wire fabric because of the overall color bright, if there is a light metal, can reflect the specific metallic luster. But note that not only the characteristics of metal wire fabric in metallic luster, and anti-static, with anti radiation, more conducive to regulate all aspects of the body
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?
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 is the difference between carbon fiber and wire heating?
Carbon fiber heat is not transmitted through the medium, but far infrared light radiation to the human body, the heat transfer directly to the human body tissues and organs
