Which is the higher price of hot dip galvanizing or hot dip aluminum, and how much is the difference

Paint anti-corrosion (1) anti-corrosion principle: pure zinc powder is dissolved in solvents, additives and film-forming substances to form a zinc-rich primer, which is brushed on the workpiece to be pre-corroded, and solidified on the surface of the workpiece with the help of film-forming substances. On the one hand, it isolates the corrosive medium from soaking the steel and achieves the anti-corrosion effect, and on the other hand, the zinc-rich paint has a cathodic protection effect. (2) paint coating performance zinc-rich paint is an anodic coating, but because its film-forming substance is organic matter, with the extension of time, the environment is ever-changing, organic matter will eventually age, pulverization until failure, which will lead to the oxidation and shedding of zinc powder particles; On the other hand, because the surface of the matrix after pickling and passivation is smoother, the adhesion of zinc-rich paint decreases, and it is difficult to obtain the actual anti-corrosion effect.

Hot-dip galvanizing (1) anti-corrosion principleHot-dip galvanizing is the plating process of immersing the workpiece to be plated in the molten metal zinc tank, so as to form a pure galvanized layer on the surface and a zinc alloy coating on the sub-surface to achieve the protective effect of steel. (2) Hot-dip galvanized layer performance The hot-dip galvanized coating is relatively dense, which can effectively hinder the corrosion medium from immersing the human matrix and realize the cathodic protection of steel; The hot-dip galvanized coating is thinner, generally only 30-50um, and can reach 85um for some larger workpieces, even if the dipping time is extended, the thickness of the zinc layer does not increase much, and the coating is uneven at the same time, and the thickness is not easy to control; The coating adhesion is poor, slightly better than that of zinc-rich paint. In addition, the adhesion of hot-dip galvanized coating is directly affected by the quality of surface pretreatment of the workpiece. The anti-corrosion life of a single hot-dip galvanized coating is longer than that of zinc-rich paint, which is mainly determined by the thickness of its coating.

Arc spraying anti-corrosion (1) anti-corrosion principle: arc spraying is the use of special spraying equipment, so that the sprayed metal wire is melted under the action of low voltage and high current, and the compressed air is sprayed to the metal components of pre-sand throwing and rust to form an arc spray zinc and aluminum coating, and the anti-corrosion sealing coating is sprayed on it to form a long-term anti-corrosion composite coating. The metal spray coating acts as an anode to cathodic protect the steel components, and the thicker coating also prevents the corrosive medium from infiltrating the human matrix. (2) The coating characteristics have high adhesion, and its adhesion is incomparable with zinc-rich paint and hot-dip galvanizing.

In addition, according to the Japanese industrial standards for the arc spraying coating impact bending test, etc., the test results are not only fully in line with the standard, but also by the field engineering and technical personnel called "laminated steel plate", very suitable for the long-term anti-corrosion treatment of coal mine shaft steel structural parts that are often subject to impact and vibration; Long life, arc spray coating thickness determines the corrosion resistance life of the coating, generally more than 30-60 years.

Hello, I have inquired for you that hot-dip galvanizing is 1080 yuan a ton, and the thickness of hot-dip galvanizing is 50-90 microns, which is equivalent to 10-20kg t of zinc. According to the tonnage, zinc price * zinc consumption * is the basic hot-dip galvanizing, such as zinc price according to 6000 yuan, zinc consumption according to 15kg, then** = 6000 * yuan t, if my answer is helpful to you, please also give a like (in the lower left corner of the evaluation), look forward to your like, your efforts are very important to me, your support is also the driving force for my progress. If you feel that my Xie Changyuan answer is still satisfied with the collapse, you can click on my avatar for one-on-one consultation.

Finally, I wish you a bright and healthy body and a happy mood!

Hot-dip zinc is expensive. Hot-dip galvanizing, as an effective way of metal corrosion, has been widely used in metal structure facilities in various industries. Hot-dip galvanizing is to immerse the derusted steel components into about 600 high-temperature melted zinc liquid, so that the surface of the steel structure chain is attached to the zinc layer, and the thickness of the zinc layer shall not be less than 65 m for thin plates below 5mm, and not less than 86 m for thick plates.

So as to play the purpose of anti-corrosion.

Difference Between Hot-dip Galvanizing and Hot-dip Galvanizing:

1. The concept is different. Hot-dip galvanizing is an effective way of metal corrosion, which is mainly used in metal structure facilities in various industries.

2. The process of making wild chops is different. Galvanizing refers to the surface treatment technology of coating a layer of zinc on the surface of metal, alloy or other materials to play a role in aesthetics and rust prevention. Hot-dip galvanizing is to use zinc-tin solution to wrap up the hardware, which is about five times longer than the traditional galvanized anti-rust time, and the general outdoor construction is the way of hot-dip galvanizing, and the salt water test can be done for about 36 hours.

3. The technology used is different. Hot-dip galvanizing is to coat the surface of angle steel, channel steel and other metals with a zinc layer, which is used by Songzhichang to achieve the beauty of convenience and the rust prevention of metal. The zinc-tin solution used in the hot-dip galvanizing plant is used to protect the workpiece. <>

Summary. Extended information: Hot-dip galvanizing is the reaction of molten metal with iron matrix to produce an alloy layer, so that the matrix and the coating are combined.

Hot-dip galvanizing is to pickle the steel parts first, in order to remove the iron oxide on the surface of the steel parts, after pickling, through the ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then sent to the hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The principle of hot dipped galvanizing is simply to immerse the cleaned iron parts in a zinc bath through the wetting action of the plating agent, so that the steel reacts with molten zinc to form an alloyed film.

A good hot-dip galvanizing operation should be that each process is under strict control and fully exerts the function of the process. And if the operation of the previous process is not good, it will cause a chain of adverse reactions in the subsequent process, and greatly increase the operating cost or cause poor hot-dip galvanized products. If the pretreatment is poor, the molten zinc cannot react with the steel normally and completely to form the most perfect galvanized film tissue.

If the post-treatment is not good, it will destroy the appearance of the galvanized film and reduce the value of the product.

Dear, I am very honored to answer for you: hot-dip galvanized ** is about 4600 yuan. The ** of hot-dip ballast only galvanized is about 5,000 yuan.

The ** of galvanized pipes varies slightly according to different diameters. Hot-dip galvanized is about 5,500 yuan per hall of travel and careful tons. Cold plating (electroplating) is pretending to be a layman, and the plating is too thin and quickly corrodes.
