Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Electroplating solution with solid particles or excessive foreign metal impurities, will lead to such problems. Solution: If the large roll galvanized wire to the above coating is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.
Through the maintenance of galvanized wire, it can not only greatly prolong its service life, but also improve its efficiency in the daily use process. Because the labeled electrode potential of zinc is -0.762v, which is negative than iron, zinc becomes the anode when the galvanic cell is formed after being corroded by the medium. It itself is dissolved to protect the steel matrix. The duration of the protection of galvanized wire layer has a great relationship with the thickness.
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.
In GENERAL, THE HARDNESS OF A METAL IS OFTEN CONSIDERED AS THE RESISTANCE OF a MATERIAL TO COMPRESSION PLASTIC deformation, scratches, wear, or cutting. In the adjustment of zinc dip distance of galvanized wire, keep the original speed unchanged, according to the time of zinc dip, wire diameter, and then estimate the zinc dip distance. By adjusting the zinc dipping distance, the zinc dipping time of various specifications of steel wire is shortened by 5s on average compared with that before debugging, so that the zinc consumption is reduced, the zinc consumption per ton of steel wire is reduced from the original 61kg to 59.4kg.
- Barbed rope often appears in another model: 14*14# barbed rope, 12*12# barbed rope, 12*14# barbed rope, among which the diameter of 14# wire is about 2.0 mm, the diameter of 12# wire is about 2.65 mm, there is a non-standard 2.25 mm is also commonly used line. According to this specification, a kilogram of 14*14# barbed rope is 12 meters, a kilogram of 12*14# barbed rope is 8 meters, and a kilogram of 12*12# barbed rope is about 5 meters.

First of all, the protective layer of zinc-iron alloy can prevent the steel wire from being corroded by oxidation. The zinc metal reacts with water and oxygen to form a dense zinc oxide layer, which forms a physical barrier to prevent oxygen and water from entering the inside of the steel wire, reducing the chance of corrosion. Compared with ordinary steel wire, hot-dip galvanized wire is more resistant to corrosion in humid, high humidity or corrosive environments such as acid and alkali, so it is more durable.

This characteristic makes it a staple in recipes for cakes, cookies, and bread.
The ability of sodium bicarbonate to neutralize acids makes it an excellent antacid for treating conditions like heartburn and indigestion. When swallowed, sodium bicarbonate reacts with excess stomach acid (HCl) to form sodium chloride (table salt), water, and carbon dioxide—providing symptomatic relief by raising the pH of gastric contents. This property has made sodium bicarbonate a staple in many households as a quick remedy for acid-related discomfort.
However, the consumption of maltodextrin raises certain health considerations. While it is generally classified as safe by health authorities such as the FDA, some individuals may experience adverse effects, particularly those with sensitivities to corn or specific dietary restrictions. Furthermore, because maltodextrin is derived from starch, it can cause rapid spikes in blood sugar levels, which may pose risks for individuals with diabetes or those monitoring their glycemic intake. This has prompted some nutritionists and consumers to approach maltodextrin with caution, especially in products consumed frequently or in large quantities.
Sodium carbonates (E500) play a vital role in modern food production, affecting everything from the basic texture of baked goods to the stability and flavor of emulsified sauces. As consumers become more aware of food additives and their functions, understanding the role of E500 becomes essential. Recognizing that these additives are not merely fillers or preservatives but pivotal components that enhance our everyday food experiences helps demystify the complexity of food manufacturing. With ongoing research and regulatory oversight, the food industry continues to utilize E500, ensuring that products remain safe, enjoyable, and consistent in quality.
