Introduction to Hot Dip Galvanizing Agent Technology
I. Technical background
The commonly used galvanizing processes in the industry include hot-dip galvanizing, electro-galvanizing, mechanical galvanizing, and thermal spraying (plating), etc. Among them, hot-dip galvanizing accounts for about 95% of the total galvanization, and hot-dip galvanizing is used for zinc It accounts for 40% of zinc production worldwide, and about 30% of zinc production in China. Due to its mature technology and low cost, hot-dip galvanizing has become the most widely used anticorrosion technology for steel materials. The overall characteristics of the national batch hot-dip galvanizing industry are: a large number, wide distribution, and low industrial concentration; affected by the radius of bulk material transportation and logistics costs, generally provinces with industrial bases have hot-dip galvanizing (leaching) zinc companies Run in production. The market size of the batch hot-dip galvanizing industry is huge, and the products after hot-dip galvanizing can be applied to hardware workpieces, power iron bridges, communication iron bridges, railways, highway protection, street light poles, marine workpieces, construction steel structure workpieces, substation auxiliary facilities, etc. field. At present, the areas with a high concentration of batch hot-dip galvanizing plants in China are basically in the Yangtze River Delta Economic Belt, Tianjin-Jiangxi-Luhai-Bohai Bay Economic Belt, and the Pearl River Delta Economic Belt, and later in Sichuan, Hubei, Chongqing, and the Northeast of the Yangtze River. With the development of the Belt and Road Initiative, new batches of hot-dip galvanizing plants have also begun in Inner Mongolia, Qinghai, Gansu, and Xinjiang. It is initially estimated that the annual hot-dip galvanizing plant's processing capacity exceeds 100 million tons and the market output value reaches 100 billion yuan. The batch hot-dip galvanizing industry is relatively backward in overall process technology level, relatively low in automation level compared to the electrogalvanized market, uneven process control level, low overall industry level, and serious pollution. As the government's environmental protection policy tightens, environmental protection pressures increase. In the process of batch hot dip galvanizing, the annual consumption of traditional zinc-ammonium plating solution is about 500,000 tons. Although the process has the characteristics of low cost, high stability and good plating effect, in recent years, with the hot dip galvanization industry, With the implementation of clean production, the traditional zinc-ammonium plating aids generate a large amount of smoke during the production process, which has a negative impact on the environment. The water quality and air pollution caused by the ammonium chloride component in the plating aids to the surrounding environment cannot be ignored. The problem. This technology researches the ammonium-free plating aid and the ammonium-free plating aid process, and replaces the traditional zinc-ammonium plating aid with the ammonium-free plating aid to fundamentally realize the clean production of the hot dip plating industry.
1. Product Features
(1) The smog is small and does not leak.
Using this technology product, the product is an ammonium-free formula, which can reduce more than 70% of the smog in the galvanizing process, which can significantly improve the operating environment, reduce the emission of ammonium-containing exhaust gas, and there will be no missing plating in the production process.
(2) Does not burst the pot, the appearance quality of the product is high.
After processing with the product of this technology, the phenomenon of hot pot explosion does not occur when the galvanized parts are lowered into the pot, and the surface quality of the plated product is high, and the surface smoothness and gloss are improved compared with ordinary products.
(3) Save zinc ingots.
The use of this technology product can save an average of 3-5 kg of zinc ingot resources per ton of plated parts, which can significantly reduce the cost of the galvanizing process and has obvious economic value.
(4) Self-purification characteristics.
The products of this technology have self-purification characteristics, which can significantly prolong the service life of the plating solution, and the cleaning cycle of the plating solution can be at least doubled.
(1) Storage and transportation of plating aids: The plating aids are clear liquids, mainly water-solvent products, solutes are common chemical products, pH value is 3-4, flammable and explosive components are not included, and they can be transported by ordinary freight vehicles. General workshops should be stored away from light and protected from moisture.
(2) Application method of plating aid: If the original zinc-ammonium plating bath is changed to new products, one-third of the total amount needs to be replaced at one time, which can reflect the product effect; each 10-15 tons of product (in small pieces) Calculate), add 35 kg of this product, and replenish the rest; if you use this product in a new tank, after configuring according to the requirements, add 35 kg of this product every day, and replenish the remaining water for sustainable use.
(3) Operate the downstream process on site. If there are special requirements for the product, please inform the technical staff in time. Technical support can be dynamically deployed according to specific needs.
(4) If there are special fluctuations in the process or workpiece, please contact the technical staff in time to adjust the formula.
(1) If there is a little turbidity in the treatment solution, it can be used after stirring or shaking without affecting the use effect;
(2) When the material of the workpiece is different, the inconsistency of the color of the workpiece after the treatment liquid is normal;
(3) Human health matters: If the skin is contaminated with the treatment solution during use, rinse with water and dry it. When eating by mistake, rinse your mouth with water, drink milk or egg white, do not lavage your stomach, and do not induce vomiting;
(4) It is strictly forbidden to mix, transport and store with other inorganic substances, organic substances, oxidants and reducing agents;

Fourth, benefit accounting
The economic benefits are calculated by taking a single-pot small galvanizing enterprise (> 600 ° C high-temperature galvanizing pot) as an example, with a processing capacity of 300 tons / month and a zinc consumption of 70 kg / ton. Zinc ingot savings are calculated at 3 kg / ton, and 900 kg of zinc ingot resources can be saved per month. Zinc ingots at 24,000 yuan / ton can save costs of 21,600 yuan. According to the 35 kg / 10 ton addition amount, monthly needs Adding flux is about 1 ton, the price is 10,000 yuan / ton, and the monthly addition cost is 10,000 yuan / month. It is assumed that the addition cost of traditional flux is 0.5 million yuan / month (including the general cost of adding anti-explosion agent is greater than this amount) ), The added cost increases by 0.5 million yuan / month; then the comprehensive economic benefit is 2.16- (1-0.5) = 16.6 thousand yuan. In addition, the product has the characteristics of low smoke, no leakage plating, no pot explosion, high product appearance quality, and self-purification of the plating solution. The comprehensive advantages are particularly obvious. The larger the scale of the galvanizing production line, the greater the overall benefits. The application of new technologies can significantly alleviate the urgent industrial technology demand problems caused by the upgrading of environmental protection requirements of related enterprises, and can provide strong guarantees for reducing environmental pollution in production areas, improving the working environment of operating workers, increasing economic benefits of enterprises, and increasing local government taxes. . At present, this technology has been promoted and applied in more than 40 galvanized enterprises in Taigu County, Shanxi Province, and has produced significant economic and environmental benefits. Once the technology is applied in a large-scale industrialization in the industry, it will solve common technical problems in the industry and drive the industry. Technical progress has a strong impetus.
