  • First, you might ask: “Why do you need to choose a heavy duty sewing machine?” Well, the answer is pretty simple. Heavy duty sewing machines are usually used in sewing thicker materials but can be successfully used for thinner ones, too.

  • Another advantage of heavy-duty bag making machines is their cost-effectiveness. By producing bags in-house, manufacturers can save on outsourcing costs and have better control over the quality and customization of their packaging. This can lead to increased profitability and competitiveness in the market, as companies can offer a wider range of packaging solutions to meet the diverse needs of their customers.

  • (4) Stop the use of more than two strands of galvanized iron wire around the operation method.

  • As we all know, even if it is the same kind of steel wire, because of the steel making process, wire drawing process and equipment are not the same, so the quality of steel wire production is not the same. Due to the different mechanical properties of steel wire itself, flattening process and equipment, the width and elongation of steel wire in the flattening process have different effects. Therefore, in the selection of wire diameter, the following three factors should be considered:

  • People who want to keep birds for the long term need to know how to choose the right cage and how to raise them scientifically. It’s all about the birds’ daily life and health. Only by knowing more about the various aspects of raising birds can they be raised healthy and lively, singing freely and suitable for viewing.

  • 5, according to the thickness of the wire diameter to adjust zinc dipping time
  • iron

  • After proper heat treatment or cold drawing hardening, high carbon steel wire has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is acceptable, but welding function and cold plastic deformation ability is poor.

  • Breeding cattle and sheep with barbed rope effect is better, because the advantages of barbed rope are more. So the thorn rope used to do animal husbandry effect is good?

  • Cyanogen bath has alkaline zincate bath, ammonium bath, sulfate bath and ammonia chloride bath. Cyanide galvanized solution plating ability is good, the coating lubrication, in production has been selected for a long time, steel mesh chromium plating: chromium plating layer has a high hardness, according to the bath composition and process conditions are different, the hardness can be changed in a large scale 400~1200HV.

  • After a long time of use, it will not rust after the corrosion layer on the surface of the hot-dip galvanized barbed wire has problems, because the material inside the stainless steel barbed wire is the same as the material on the surface.
  • Knife width: 6 (mm)
  • barbed

  • Greenhouse special electroplating process iron wire blackening solution:

  • Barbed wire welding is the reason for the occurrence of black spots is because the welding wire action to be timely in the melting time, development should be appropriate, no argon, long time burning, current, distance, tungsten needle blunt, molten pool temperature is high, is the root cause of blackening. Continuous burning, is about the active welding machine energy selection, machine welding will appear black spots.
  • Stainless steel barbed rope is often used in various engineering projects because of its good anticorrosion ability, but it is difficult to be accepted by ordinary families because of its high price. So what material of barbed rope has better anticorrosion ability?

  • 6, passivation to remove hydrogen parts should be passivation after the removal of hydrogen, passivation before the application of 1%H2SO4 or 1% hydrochloric acid activation 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.

  • With the improvement of people’s living standards now, many families are keeping some small pets, these small pets also need a stable nest, pet cage has become a more important choice of people, each pet habits and living habits will choose to adapt to the cage.

  • Heavy duty hexagonal mesh made of steel wire by special machinery woven into a hexagonal mesh net. This kind of mesh can be cut and assembled into fence mesh, mountain hanging mesh, vegetation three-dimensional mesh, composite, etc. Aliases: Gabion mesh, heavy hexagonal mesh, ecological mesh, wire mesh, etc.

  • The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion to the matrix. Galvanized wire can be zincate galvanized or chloride galvanized process, should use appropriate additives to obtain the low carbon steel wire standard requirements of the coating. When galvanized wire after light plating should be light treatment. Control the temperature of the bath of galvanized wire.
  • Materials of qualified quality should be kept marked for reference when used. In order to remove the surface film, surface inclusion and other defects on the surface of the large roll galvanized wire on the surface of the sedimentary layer to the local surface, it can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. The presence of small homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of too many solid particles can cause explosion.
