Special desiccant for car lights
Tepugo's special desiccant for car lights is specially designed to deal with the fogging phenomenon of car lights, and is innovatively developed in strict accordance with the use environment of the car lights. Car light desiccant must meet key technical requirements such as high moisture absorption rate, no moisture release, high temperature resistance, and can work normally in low temperature environments, dustproof and leakproof, long lasting action, environmental protection and safety. In this regard, Topco invested a lot of manpower and material resources and established a special research and development team. After three years, it overcame many technical difficulties and successfully developed a special desiccant for car lights. The three original technologies of solidification, dispersion and pore creation independently developed by the company have achieved a revolutionary leap in the field of car lamp desiccant technology and are the first of their kind in China.
Innovative technical advantages of special desiccant for car lights
☆ High moisture absorption rate, complete moisture absorption☆
The special desiccant for car lights has a moisture absorption rate of up to 180%, and its moisture absorption effect is more than 6-9 times that of ordinary desiccants such as silica gel (moisture absorption rate 28-30%) and montmorillonite (moisture absorption rate 22-26%). At the same time, the special desiccant for car lights is a predatory chemical hygroscopic. As long as there is moisture in the air, it can rob it. By formulating the appropriate dosage, the moisture in a specific space can be completely absorbed. The rapid moisture absorption speed can quickly reduce the humidity of the space environment to within the ideal humidity, creating an extremely dry environment. This feature is especially suitable for product performance protection and storage and transportation protection that have strict requirements on environmental humidity.
☆ High temperature resistance, high efficiency and long lasting☆
The special desiccant for car lights can withstand high temperature working environment of 110℃. At the same time, by adjusting the formula, two products, fast-absorbing and slow-absorbing, are made and used together. The function of the fast-absorbing formula is to first completely absorb the moist air that originally existed in the inner cavity of the lamp; the function of the slow-absorbing formula is to deal with the later use environment. Even with the intrusion of trace amounts of moisture, the long-lasting service life of 5 years can be achieved by adjusting the formula, thereby ensuring efficient and long-lasting moisture absorption.
☆ Cures after moisture absorption to prevent leakage☆
As moisture absorption progresses, the moisture absorbed by the desiccant for car lights solidifies with the desiccant to form a massive solid, completely solving the leakage problem.
☆Double guarantee of dustproof and waterproof packaging☆
The special desiccant for car lights is also packaged with a new generation of packaging material (Dute paper) independently developed by Tepuco. The technical characteristics of Dut paper are unidirectional and selective transmission, that is, only air is allowed to pass through and Water molecules cannot pass through.
☆ No moisture is released during the moisture absorption process☆
Ordinary silica gel and montmorillonite desiccants are physically hygroscopic and only temporarily store the adsorbed water in the micropores. When the ambient temperature is high (around 60°C) or the humidity is reduced (the ambient humidity is lower than its hygroscopic value) Moisture content), the absorbed moisture is released into the space environment again and again, and does not have a real moisture-proof effect on the product. Although calcium chloride desiccant is also chemically hygroscopic, calcium chloride becomes liquid after absorbing moisture and has a large water vapor pressure. When the humidity of the space environment is low, the liquid calcium chloride will release a large amount of moisture and return the water to the desiccant. Release into the air. The special desiccant for car lights is different. It is a predatory chemical hygroscopic. Part of the absorbed moisture is firmly locked in the form of crystal water, and the other part participates in the curing reaction and is converted into a solid substance. Once the moisture is absorbed, it will no longer be available. It will be released into the environment again. This process is an irreversible moisture absorption process to ensure a stable and dry environment.
☆ All-weather performance☆
The special desiccant for car lights has the ability to work all day long at high temperatures, high humidity, and low temperature and low humidity. It can still exert its hygroscopic effect under the temperature and humidity environment of -20℃~90℃, RH1~99%, and is suitable for any seasonal environment in any region around the world. . The physical adsorption desiccants represented by silica gel and montmorillonite, when the temperature is higher than 40℃, their moisture absorption capacity continues to decrease as the temperature rises, and when the temperature is below 5℃, they gradually lose their moisture absorption capacity, 0℃ The ability to absorb moisture is completely lost below. As moisture absorption progresses, the moisture absorbed by the desiccant for car lights solidifies with the desiccant to form a massive solid, completely solving the leakage problem.
☆Safety and environmentally friendly☆
The raw materials used in the special desiccant for car lights are non-toxic, harmless and odorless, and are synthesized from degradable natural minerals. They have been tested by the international authoritative organization SGS and are fully compliant with the EU RoHS and REACH standards and do not cause any pollution problems to the environment.
On May 16, 2024, the 5th Intelligent Car Lighting Innovation Technology and Supply Chain Forum organized by Chongqing Automobile Club and Aibang Smart Car Club will be held at Chongqing Jinling Hotel.
