Key words: What is the good anticorrosion technology of steel radiator?
I. Materials
When comparing the appearance of steel radiators, besides the appearance and feel, painting and workmanship are several important points to judge the quality of radiators.
Feel, at least the appearance is spotless, neat and flat, and the radiator feels smooth and does not scratch;
Try to choose products sprayed with lead-free plastic powder when painting. This is because the temperature of the heating equipment is relatively high. Therefore, if the surface of the product is just ordinary spray painting, a chemical reaction will occur at high temperature, releasing formaldehyde. You must choose a radiator sprayed with environmentally friendly materials.
Second, the welding process
High-temperature furnace welding and manual welding are easier to understand. High-temperature furnace welding equipment melts the copper paste at a high temperature of 1083℃, and then evenly penetrates into the gap of the pipe wall, which is integrated with the radiator, so that the radiator is welded firmly, without virtual welding or missing welding, welding scar and beautiful appearance.
Weimei radiator is one of the earliest enterprises that use high-temperature furnace welding equipment in China, and has the first three-dimensional high-temperature furnace welding equipment in China. Manual welding is awkward, with obvious welding scar, ugly appearance, easy to come off welding and water leakage.
Third, the anti-corrosion process
Because the steel radiator itself does not have anti-corrosion function, it mainly depends on the anti-corrosion treatment done by the manufacturer. However, the anti-corrosion technology of manufacturers is uneven, and internal anti-corrosion is also the key point to distinguish big brands from small brands.
Every heating season, there are always several reports about the radiator leaking and bursting, which leads to "the water is full of golden mountains". Many reasons are because the radiator corrosion is not up to standard. The so-called internal corrosion protection of radiator is not as simple as painting a layer of paint and a color. Every working procedure should be operated according to the standard, so as to achieve the effect of "anti-corrosion". From the point of view of internal anti-corrosion filling, if the automatic vacuum filling technology is adopted, all the air in the radiator can be pumped away, and when there is no air in the radiator cavity, the preservative can be evenly applied to the weld inside the radiator to achieve the best effect in all directions. On the other hand, naturally filled preservatives are easy to generate bubbles in the radiator, which greatly reduces the anti-corrosion effect, which is similar to that without filling, and even makes the local corrosion of products more serious.
4. Material processing technology
In view of the problem that traditional steel radiators are easy to be oxidized and corroded, some enterprises have developed an upgraded product-anti-corrosion King Kong. Introduction of anti-corrosion king kong: anti-corrosion king kong 6030F is a patented product. It is a subversive steel radiator, with steel cost performance and corrosion resistance much higher than that of ordinary steel radiators.
Anti-corrosion King Kong 6030F radiator adopts special Mg-Al alloy installed at the bottom of steel radiator, and the active Mg-Al alloy reacts with ions in water first to avoid "under-scale corrosion" and "bottom metal corrosion". The consumption time of a magnesium-aluminum alloy is more than 15 years, which greatly prolongs the life of the radiator, does not need full water maintenance, and the warranty period is 15 years.
