With government subsidies, tax incentives, and the introduction of preferential loans, the air-to-water heater (heat pump water heater) industry has seen significant support. These systems offer energy efficiency, safety, and comfort, which have gained increasing consumer acceptance. However, as these units become more widespread, various issues have emerged, particularly concerns about corrosion and scaling in hot water tanks. This issue is closely tied to the geographical characteristics of our region. In many parts of our country, including saline-alkali soils and coastal areas, the high chloride ion content in water leads to corrosion and even pipe perforations in copper components, ultimately causing equipment failure.
As a relatively new technology, air-to-water heaters still face challenges in terms of consumer education and post-sale service. This lack of awareness has led to consumer dissatisfaction and misconceptions. Addressing the corrosion problem requires a comprehensive approach. First, it's important to identify whether the water contains chloride or sulfur ions by checking for moss growth. Corrosion typically occurs at weld points; uneven welding under high temperatures can lead to oxidation, making these areas especially vulnerable. Applying a thin layer of gold or steel over the welds can help prevent corrosion.
When consumers encounter product issues, contacting the seller immediately is crucial to minimize potential losses. Manufacturers also have a responsibility to address common problems proactively by offering solutions and educating consumers about proper maintenance. Additionally, developing corrosion-resistant materials and improving manufacturing processes could significantly enhance the longevity and reliability of these systems. By addressing these concerns head-on, we can ensure that air-to-water heaters continue to provide long-term benefits to users while fostering trust in this innovative technology.
The media for the production of cosmetics include glycerin, Carbomer, hyaluronic acid, thickener, emulsion, cream and so on. They have special requirements for the structure, hygiene level and cleaning system of the lobe pump in the production process. Our rotor pump has obtained 3A, FDA and other certification, meets food grade requirements, and supports CIP system cleaning. Different different medium viscosity choose different rotation speed to meet the production process requirements of various cosmetics.
