There are two main types of driers, each serving different purposes and industries. The first is the dishwasher drier, specifically designed for the final rinsing stage of a dishwasher. It works by reducing the surface tension between the dishes and water, allowing them to dry quickly without leaving behind any unsightly water spots or streaks. This product is safe for all types of tableware and will not damage materials or the dishwasher itself. It comes with a fully automatic dispenser that ensures the rinse solution maintains a concentration of 0.01% to 0.1%, typically used with water temperatures ranging from 80°C to 90°C. Different dishwashers may require varying concentrations, so it's important to follow the manufacturer’s guidelines. The drier also improves wettability, speeds up drying time, and helps keep your dishes clearer and brighter. Additionally, it contains a defoamer that eliminates foam and helps remove food residues more effectively, making it an essential part of your dishwashing routine. The second type is the industrial drier, commonly used in the coating industry to speed up the drying process of paint films through oxidation and polymerization. Traditional driers like cobalt, manganese, lead, zinc, and calcium-based organic acid soaps have been widely used, but they often come with high costs or potential toxicity. In recent years, rare earth driers have emerged as a safer alternative, though they can only partially replace cheaper cobalt-based driers. The coatings industry has long been looking for a new, non-toxic drier that can completely replace cobalt, as this would improve both safety and efficiency. Industrial driers are usually solvent-based, which allows them to evaporate quickly, making them ideal for large-scale applications. The key difference between the two lies in their toxicity levels. Dishwasher driers must be non-toxic since they come into direct contact with food and tableware, while industrial driers are generally solvent-based and designed for use in controlled environments where safety precautions are already in place. Understanding these differences helps you choose the right drier for your specific needs, whether it's for home use or industrial application. Ni-Cd Battery Emergency Exit Sign
These emergency exit signs usually equipped with recharged a 3.6V Ni-cd battery inside the hosing. It has up to 500 times backup powered. The battery is protected by a low voltage cut-off circuit. Also, the emergency escape signs specialized to use the fire-resistant housing at the engineering level. Upon failure of the normal utility power, an internal transfer switch provides emergency time for at least 90 minutes. The charger initiates powered back the battery in 24 hours. The exit sign is suitable for wall or ceiling mounting. Plus, there is an indicator light and a test button on the unit so that you can periodically check that it is functioning properly.
