  • Sewing has been an integral part of human civilization, allowing us to create and repair clothing, fabrics, and various textile products. Among the myriad of sewing techniques, lock sewing stands out as a reliable method for providing strength and durability to seams. This article explores the significance of lock sewing, its applications, and why it remains a favorite among seamsters and tailors.


  • One of the main advantages of a walking foot cylinder arm sewing machine is its ability to sew through multiple layers of fabric with ease
    walking
    walking foot cylinder arm sewing machine. This makes it ideal for sewing projects such as upholstery, quilting, or other heavy-duty sewing tasks. The walking foot mechanism helps to ensure that all layers of fabric are sewn together evenly, creating a professional-looking finish.

  • Correction is the hot galvanized wire or cold galvanized wire secondary treatment, the surface after correction is smooth and shiny, and the tensile strength is stronger, so that it is not easy to break. Now it is usually used for screen industry will be changed, which can improve the quality. In addition, clothes rack, communication, high voltage line will be changed to prevent breakage.

  • One is to do a good job of galvanized wire packaging, avoid bump, to ensure the integrity of the zinc layer;
  • Arrived in other ways can’t end effect of the inclination of hook flower network structure in essence is void, water permeability, the natural effect of groundwater and filtering effect has a strong inclusive, suspended in the water content and silt accumulation in fill in crevices, applied to mountain protection, is conducive to the growth of natural plant, beautify the grass spraying to arrive late his curing effect, Gradually restoring the original ecological environment is a perfect connection between beautification and protection.

  • Good galvanized wire, plating thickness of 3- 4 mm, zinc adhesion should be less than 460 grams/m, that is, the average thickness of zinc layer is not less than 65 microns. When the thickness of plated parts is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer should not be less than 86 microns. Standard galvanized wire coating must be uniform, galvanized layer basically uniform with copper sulfate solution test etching five times no dew iron. For standard galvanized wire coating adhesion requirements, the zinc layer of plated parts should be firmly combined with the basic metal and have enough adhesion strength, after hammer test does not fall off, not convex.

  • After electric galvanizing hot galvanizing. Electroplated copper and other common applications of screen consumption. The weaving of the binding of the building steel wire mesh has the first braided after plating, plating after weaving and other methods, after the disposal of the wire mesh or wire mesh has good corrosion, oxidation resistance characteristics, can be used in the construction, petroleum, chemical, aquaculture, garden protection, food processing and other industries of reinforcement, protection and insulation.

  • In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting. In the debugging of zinc wire dipping distance, keep the original speed unchanged, according to the time of dipping zinc, the diameter of steel wire, and then estimate the dipping distance. By adjusting the zinc immersion distance, the zinc immersion time of steel wire of various specifications is shortened by 5s on average compared with that before debugging, so that the zinc consumption per ton of steel wire is reduced from 61kg to 59.4kg.

  • Cold wire drawing is mainly used in the production of hardened low carbon steel wire, with a diameter of 8 mm steel bar to play a fixed role in the development of the construction industry has played a role in promoting the development of the construction industry, widely used. The bonding and anchorage performance between cold wire drawing and concrete is good. When used in components, the phenomenon of cracking in the anchorage area of components and damage caused by steel wire slip is fundamentally eliminated, and the bearing capacity and anti-cracking capacity of the end of components are improved.

  • Therefore, when the zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms are diffused with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with the iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with the zinc and sinks into the bottom of the hot galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

  • ⑵ Can realize the welding of large plate, steel frame, plate – tube, rod – rod, tube – tube and other profiles.

  • The barbed wire factory will store the blade barbed wire inventory in the appropriate place, because it understands the product characteristics.

  • Generally speaking, it is necessary to install thorn rope in pasture, which is simpler and saves time and effort. It is better managed because it is full of spikes that keep livestock away from the barbed fence.

  • Large coil galvanized wire in the zinc immersion distance debugging, keep the original speed unchanged, according to t= KD to determine the zinc immersion time (1), where: t is the zinc immersion time is constant, take 4-7D is the diameter of steel wire mm, and then estimate the zinc immersion distance. By adjusting the zinc dip distance, the zinc dip time of steel wire of various specifications can be shortened by 5s on average. In this way, the zinc consumption per ton of steel wire decreases from 61kg to 59.4kg.

  • Post-plating (passivation, hot melting, sealing and dehydrogenation, etc.) for the purpose of enhancing protective properties, decoration and other special purposes. After galvanized, chromate passivation or other conversion treatment is generally required to form the corresponding type of conversion film, which is one of the key processes to ensure the quality of post-plating.

  • The common specifications of small hexagonal net in production are: the width is 1.22m, and the commonly used width is generally 1m. In terms of length, the small hexagonal net basically has no limitation. 1-100 meters can be produced. The production diameter of small hexagonal mesh is generally No. 27 wire to No. 18 wire, and the aperture size is 0.95cm-5.08cm.
