In the winter season, not only the road is easy to fog, car headlights (halogen, xenon, LED lights) are also easy to fog, especially in the cold and wet southwest, many owners will often encounter headlights fog.
Once the headlamp fog, the fog in the lampshade will affect the light transmission, and even make the direction of the headlamp beam offset, resulting in astigmatism, which affects the driving safety of the owners. So why are headlights foggy? In fact, there are two main reasons:
First, the temperature difference is too large
Most headlamps have a ventilated rubber tube on the back cover. This rubber tube is mainly used to discharge the heat generated by the headlamp, so as to maintain the normal temperature of the headlamp. But also because of the existence of this ventilation rubber tube, some water vapor will follow, attached to the lampshade to form a mist. Especially in the winter, the temperature difference is large, the air in the headlamp meets the cold lampshade will form a large number of water mist.
Second, water vapor infiltration leads to
If the tightness of the headlight is not good, it will also lead to the water vapor in the environment to infiltrate into the interior of the lamp body. Once the internal temperature of the headlight is lower than the critical saturation temperature of water vapor, there will be fog phenomenon of the headlight.
In short, no matter what causes the headlights to fog, we must pay special attention to. And in the headlights in the headlamp desiccant is a good method, it can always keep the headlights clean, not easy to fog, let your driving more at ease.
The common headlamp desiccant on the market is magnesium chloride desiccant, a lot of lights factory comes with this kind of drying bag, because it can greatly reduce the risk of headlamp fog.
And Huawin magnesium chloride desiccant is a desiccant specially tailored for headlamps, it uses magnesium chloride as raw material, its chemical properties are stable, absorption performance is balanced, whether in low humidity environment, or in high humidity environment, moisture absorption ability is very stable.
More importantly, this desiccant is powdery before moisture absorption, and gradually condensed into blocks after moisture absorption, and there is no liquid water seepage on the surface, even if the external force is compressed and deformed, it is not easy to leak.
In addition, the outer packaging is made of high breathable, tear resistant and high temperature resistant packaging materials such as DX paper, which can lock the water even more effectively. Besides, it does not deform or break for 24 hours under the environment of 130℃. It is suitable for all kinds of automobile headlights and other electronic products.
Use is also very simple, most car lights will set up a special storage desiccant area, just put the magnesium chloride desiccant in the corresponding position. At the same time, regular replacement treatment can ensure that the headlights are not easy to fog.
If your car headlights are easy to fog, hurry for your car to choose a suitable car headlights desiccant fog. And China win magnesium chloride desiccant is a good choice.
