Recent Q&A
Question: Why Does the Water in My Dehumidifier Box Turn Yellow After Absorbing Moisture?
Answer: The yellowish color of the solution you observed is a typical characteristic of calcium chloride-based desiccants and does not indicate a quality issue. The light yellow appearance of the calcium chloride solution is primarily related to the following factors: natural mineral components, specific production processes, and its reaction with water.
Question: At what level of oil content in food is it appropriate to use triple-protection oxygen absorbers?
Answer: The core scenarios mandating the use of the triple-protection type are: 1. High-oil or high-moisture foods, and 2. Direct contact with food during application. Conventional high-efficiency oxygen absorbers may only be used when they are physically separated from the food (e.g., by internal packaging inserts) and it is confirmed that there is no risk of contact with oil or moisture.
Question: Is My Dehumidifier Bag Defective? Why Does the Collected Water “Freeze”?
Answer: When anhydrous or dihydrate calcium chloride in dehumidifier bags/boxes absorbs moisture, it first dissolves into a saturated solution that flows into the collection area. If the ambient temperature drops below the solution’s saturation point, the solution becomes supersaturated, causing calcium chloride hexahydrate crystals to form—visually resembling “ice.” Additionally, in low-humidity environments with insufficient moisture absorption, calcium chloride may directly crystallize as hexahydrate.
Question: What are the differences between your calcium chloride desiccants and SUPER DRY Desiccants?
Answer: SUPER DRY is an international company with foreign investment background and extensive industry experience, while CHUNWANG is a domestic enterprise listed on the New Third Board (Stock Code: 831880), possessing large-scale production facilities and a comprehensive quality control system. Both are leading and reputable manufacturers in the desiccant industry, with production capacity and quality stability validated by the market.
Question: What is the service life or shelf life of desiccants?
Answer: 1.Unused state (inventory storage): The quality assurance period for desiccants is typically one year. 2.In-use state (placed inside packaging): The actual effective protection duration (i.e., the time until moisture absorption saturation is reached) is not a fixed value but highly depends on the temperature and humidity of the usage environment, as well as the overall sealing performance of the packaging.
Question: How Should Used Desiccants Be Disposed Of?
Answer: Used desiccant is typically non-toxic and harmless, and in most cases, can be disposed of as general waste. Within the European Union, the disposal of desiccant waste must comply with relevant regulations, particularly EU Directive 91/689/EEC (on hazardous waste) and the implementation measures of its member states.
Question: What is your typical delivery time?
Answer: With 27 years of specialized manufacturing experience, we maintain robust production planning and supply chain systems to ensure reliable lead times. For standard products, we strive to deliver within 7–15 working days after order confirmation and receipt of deposit.
Question: How is the Quality of Your Desiccant Products Ensured?
Answer: As a desiccant manufacturer with 27 years of specialized expertise, we treat product quality as our top priority. To guarantee that every batch delivered to customers demonstrates excellent performance, safety, and reliability, we implement a strict quality assurance system throughout the entire process, supported by advanced testing equipment.
