Galvanized barrel manufacturers specialize in the factors affecting the speed of galvanizing
(1) Pre-treatment is not thorough. There is an oxide film on the surface of the workpiece, which affects the normal deposition of zinc.
(2) Poor electrical conductivity. The current is consumed on the wire and the current distributed to the surface of the workpiece is too small.
(3) The workpiece has a high carbon content. High carbon steel, cast iron parts, etc. will reduce the precipitation potential of hydrogen, accelerate hydrogen evolution on the surface of the workpiece, and reduce current efficiency.
(4) The workpiece is tied too densely. When the galvanizing is partially shielded, the coating is too thin.
(5) The bath temperature is low. When the bath temperature is low, the current density of the distribution is correspondingly reduced, and the deposition speed of the plating layer is also inevitably lowered.
(6) The sodium hydroxide content in the plating solution is high. When the sodium hydroxide content is high, the current efficiency is correspondingly reduced.
(7) The additive content in the plating solution is low. Low additive content will affect the dispersing ability, and the coating will appear too thin.
(8) The estimated area of ​​the plated part is insufficient, and the current density delivered during plating is too small.
(9) The workpiece suspension method is improper, and the distance from the zinc anode is too large, and the position should be adjusted.
(10) The workpiece is over-etched. The hydrogen evolution potential is lowered, and hydrogen evolution at the surface of the workpiece accelerates the current efficiency, thereby affecting the deposition rate of zinc. An appropriate amount of corrosion inhibitor should be added to the pickling solution. The local scale is too thick to be removed by mechanical means, and more inspection is carried out during the pickling process.
(11) Anode passivation. The effective area is reduced, affecting the normal distribution of current.
(12) The sodium hydroxide content is low. If the sodium hydroxide content is low, the current density is not high and the anode is passivated.
Steel drum manufacturing experts teach you how to distinguish between galvanized barrels and iron drums
In real life, we all use iron drums as water-filling devices, but with the increasing use of galvanized barrels. The galvanized bucket slowly replaced the iron bucket, and the most consumers distinguish between galvanized barrels and iron drums. To understand the difference between the two products, we first need to know the main structure. The first is a galvanized bucket. In general, galvanized drums are available in two galvanizing processes, hot-dip galvanizing and cold-galvanizing. But no matter which process is made, the galvanized barrel has a galvanized layer on the surface. It protects the galvanized drum itself from external corrosion. This ensures a long service life. Iron drums are easily reacted directly with chemical elements in the air. This causes rust and other phenomena. The biggest difference between the two is that the galvanized bucket has a protective layer that can extend the service life in a limited manner, while the iron drum has a relatively short service life and is prone to rust.
Steel drum manufacturers specialize in the performance of their products
1. The steel barrel has excellent mechanical properties and high strength. Therefore, the steel drum container can be made into a thin-walled, high-pressure-resistant and difficult-to-break packaging container. This makes the safety of the packaged product reliable and easy to store, transport, handle and use.
2. The processing performance of steel drum is excellent, the processing technology is mature, and it can be continuously and automatedly produced. Steel drums have good ductility and strength, and can be rolled into sheets and foils of various thicknesses. The sheets can be stamped, rolled, drawn and welded to form packaging containers of different shapes and sizes.
3. Steel drum has excellent comprehensive protection performance. The water vapor transmission rate of steel is very low and completely opaque, which can effectively avoid the harmful effects of ultraviolet rays. Its gas barrier, moisture resistance, opacity and shelf life greatly exceed other types of plastics, paper and so on. Therefore, steel drums can maintain the quality of goods for a long time, which is especially important for food packaging.
4, the steel barrel has a special metallic luster, and is also easy to print and decorate, so that the appearance of the goods is luxurious and beautiful, and the appearance is marketable.
5. Steel drums are rich in resources, and energy consumption and cost are relatively low. Moreover, it has repeatable recyclability and is ideally green in terms of environmental protection.
Steel drum suppliers teach you about steel drum classification
According to the composition and use of the surface coating, there are mainly the following types of steel for steel drum packaging:
1. Cold-rolled low-carbon steel sheet: mainly used for manufacturing large and medium-sized transport packaging steel drums.
2. Hot-rolled low-carbon steel sheet: mainly used for manufacturing large and medium-sized transport packaging steel drums.
3. Galvanized steel sheet: Also known as white iron sheet, it is the most ideal material for barrel making. It is mainly used to manufacture various steel drums for industrial product packaging.
4, tin-plated steel sheet: also known as tinplate, is the main material for the manufacture of small steel drums, a large number of used in the can industry, can also be used to make other food and non-food small barrel containers.
5, chrome-plated steel plate: also known as Wuxi steel plate, is one of the main materials for the manufacture of small barrels, can partially replace the tinplate, mainly used in the manufacture of food packaging containers.
What are the fluctuation factors of the packaging barrel price?
According to market supply and demand, it is a normal market phenomenon that the price of packaging drums rises and falls. The main reasons affecting price fluctuations are as follows:
1. Product design and quality
If a good product has a good market, it must first have a novel design, and attract customers' attention to get the favor of customers. No matter which industry wants to have a fixed customer, in order to achieve such a realm, not only must pay attention to their own services, but also ensure that their products produce high quality products, high-quality products are the life of the enterprise.
2, the technical level of the enterprise
A company with advanced production technology can have high production efficiency and superior products. The efficiency is improved, the quality is guaranteed, so that the company can have a place in the fierce market competition, the enterprise can have its own brand, even if its product price is higher than other manufacturers in the same industry, as consumers will choose their own products.
3. The production cost of the manufacturer.
The production cost of an enterprise is one of the important factors affecting the price of an enterprise. Only the reasonable control of the cost of the enterprise can make the quantity and quality of the products produced by one enterprise higher than other enterprises.
4. Market demand situation
The market demand is large, and the price of the packaging barrel will be correspondingly improved. If everyone does not need such a product, its price will not increase.
Analysis of the performance characteristics of steel drum
Steel drums have evolved from the function of temporarily storing contents to today's industrial packaging, sales packaging, transportation and packaging, etc.; from production to circulation, consumption to form a consistent flow container, has become a means of long-term preservation of internal items, it can be said that steel drums for humans Work and life have brought about great changes and progress. Steel drums have the following performance characteristics:
