How does a plastic dehumidifier dryer solve the problem of anti-corrosion
We all know that in the plastic production industry, plastic dehumidification dryers are indispensable. In various industries, dehumidification dryers have gradually replaced traditional hot air dryers. When choosing a dehumidification dryer process, identify the drying performance of the material. Vital meaning. Materials can be divided into hygroscopic and non-hygroscopic. So let's take a look at how the dehumidification dryer solves the problem of corrosion prevention?
The so-called corrosion is actually the oxidation of metals, which is most susceptible to humidity. When the humidity in the air reaches a certain level, a very thin, invisible moisture film (ie water film) is usually formed on the metal surface. When this water film reaches a thickness of 20-30 molecules, it becomes an electrolyte film required for electrochemical corrosion. In many parts of the world, the average relative humidity can reach 75%. Using a desiccant dryer, it is easy to reduce the relative humidity to 35-50%. Under this condition, the steel will not have corrosion problems, thus greatly reducing equipment maintenance and repair costs.
In daily life, high relative humidity will cause many problems. From the storage of raw materials to the production, packaging, transportation and storage of products, all processes are affected by relative humidity. Therefore, in order to improve product quality, humidity control is necessary. Small changes in relative humidity can produce mold. Mold growth is also often caused by other humidity-related issues such as condensation and icing. Different relative humidity products will have different types of mold. But when the relative humidity reaches 70%, the mold will grow exponentially.
Mold exists in a wide range, almost in all items, even in extreme dry conditions, it will exist for a long time, and the incubation period can sometimes reach decades or even hundreds of years. Moisture can directly affect the electrical performance between electronic components, changing the original characteristics of the circuit until it is damaged. In the national air defense system, 20% of electronic product damage is mainly caused by high humidity in the air.
When the environmental humidity is high, the resistance of the insulating material of the electronic product will decrease, which will cause a short circuit of the product, and cause the product to malfunction and damage. And if the relative humidity can drop to 45%, the possibility of product damage will be greatly reduced. Compared with 80% relative humidity, damage can be reduced by half. Humid air is sometimes a conductor. Some high-power electronic equipment, such as radar or communication equipment, may produce electric sparks or even catch fire when encountering an overly humid environment. Humidity can also cause the air in the radar system's waveguide to ionize, causing malfunctions. Therefore, it is necessary to control the humidity of the air inside the radar.
