Reasons for rusting of BLACK ANNEALED WIRE material
BLACK ANNEALED WIRE material manufacturers found that BLACK ANNEALED WIRE material rusted because there is no zinc layer, but like a kitchen knife, it will rust after it gets wet with water. If the kitchen knife is not used for a long time, it will corrode and become a pair of rust. If you accidentally get water, then the BLACK ANNEALED WIRE material will produce rust. Everyone knows that the rusted iron wire will not be delayed if there is only a little rust. If the rust is serious and serious, then its quality will be poor. If there is a problem, there will be many problems in the process of use.
In the production process of small-sized steel wire ropes, electro-galvanizing is mostly selected as the raw material coating processing method of rope-making steel wires. The advantage of electrogalvanizing is that the thickness of the steel wire coating is uniform and dense, and the mechanical properties of the steel wire before and after plating change little, and can also be adjusted according to requirements; Dezincification is easy to occur. Therefore, the quality control of the galvanized layer of galvanized steel wire is very important.
In the rainy season, it is necessary to pay attention to the air humidity of workshops, warehouses and printing departments. It is recommended to use a moisture meter to measure the paper value between 8 and 10. Generally, the moisture absorption of book paper is higher than that of powder paper, and the pH value is also higher. Note that there is rust on the BLACK ANNEALED WIRE material inside the bound book. Generally speaking, if BLACK ANNEALED WIRE material is stored in normal environment (except the oxidation chamber), the phenomenon of corrosion of BLACK ANNEALED WIRE material will not occur after two years of storage, but it should be noted that during the process of handling BLACK ANNEALED WIRE material Handle with care to avoid the unsmooth pulling of the coils due to the movement of the coils, which will affect the production.
