  • Steel mesh manual binding line of the joint simple sliding, steel and concrete strength is weak, simple crack. The welded joint can accept not only pressure but also shear force. Longitudinal and transverse steel bars form a network structure, which plays a bonding anchorage effect. The number of solder joints per unit area is added when the diameter of the wire mesh is small and closely spaced. More conducive to strengthening the crack resistance of concrete, can reduce more than 75 percent of the attack of steel mesh cracks is a new, energy-efficient steel mesh structure, used in beams and columns, floors, roofs, walls, concrete pavement, bridge deck paving and other industrial and civil buildings.

  • In the process of composite plating, it is necessary to stir the plating solution to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. In the process of production, the acid activation solution can remove the corrosion products and oxide film on the surface of low carbon steel wire without excessive corrosion on the matrix. Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire.

  • The main factors causing metal rust: relative humidity of the atmosphere at the same temperature, the percentage of water vapor content and water vapor saturation content in the atmosphere, known as relative humidity. Under certain relative humidity, the corrosion rate of metal antirust oil is very small, but higher than the relative humidity, the corrosion rate increases suddenly. This relative humidity is called the critical humidity. When the humidity in the atmosphere is higher than the critical humidity, the metal surface will appear water film or water droplets, if the atmosphere contains harmful impurities, dissolved in the water film, water droplets, electrolytes and aggravate corrosion.
