As a professional nebulizer manufacturers in Shenzhen, we know that durability is the core indicator to measure the quality of humidifier nebulizer, medical nebulizer nebulizer, hydration meter nebulizer and other products. For the characteristics of different application scenarios, it is necessary to comprehensively evaluate from the material selection, process control, performance testing and other dimensions to ensure that the product maintains a stable atomization effect in long-term use.
Material corrosion resistance is the basic guarantee of durability
The core material of nebulizer tablets directly determines its anti-aging and corrosion resistance. Medical nebulizer nebulizer need to contact the liquid, we use medical grade 316L stainless steel substrate, with nano-ceramic coating, 72 hours of salt spray test without rust corrosion, can withstand the chemical erosion of common liquid; humidifier nebulizer long-term contact with the water, the choice of scale-resistant titanium alloy material, through the 1,000 hours of hard water nebulization test, the surface scaling rate reduced by 60%; hydration meter nebulizer due to the compact size, the use of high-strength piezoelectric ceramic chip, the surface scaling rate is reduced by 60%; hydration instrument nebulizer. Adopt high strength piezoelectric ceramic chip, impact resistance up to 1.5 meters drop without breakage, to meet the use of portable equipment needs.
Precision technology determines long-term stability
The process control in the production process directly affects the durability of the atomizer. We process the micro-pores of the nebulizer through laser engraving technology, and the aperture error is controlled at ±0.01mm to ensure that the nebulizer channel is smooth for a long time; the nebulizer for medical nebulizer adopts vacuum welding process, which enhances the bonding strength of the electrode and the substrate by 40%, and has been tested by 50,000 times of cold and hot shock (-20℃ to 80℃) without desoldering; the lead connector of the nebulizer of the humidifier is gold-plated with a life of more than 10,000 times, and the contact resistance is always stable at 5mΩ. The contact resistance is always stabilized within 5mΩ.
Full-scene simulation test to verify the actual durability
For the intensity of use in different application scenarios, we have designed a differentiated durability test program.
Nebulizer tablets for medical nebulizers: Simulate the continuous working mode of hospitals and conduct uninterrupted nebulization tests for 1000 hours, with the decay rate of nebulization volume ≤5% and the vibration frequency deviation controlled within ±1kHz.
Humidifier nebulizer tablets: simulating the long-term use of home scenarios, starting and stopping 10 times every 24 hours, after a cumulative total of 5,000 hours of operation, the nebulization efficiency to maintain more than 90% of the initial value;
hydrator nebulizer tablets: for the frequent use of portable equipment, 30,000 start-stop cycle test, piezoelectric element without fatigue damage, to ensure that the needs of daily use of high-frequency.
In addition, all nebulizers have passed the IP67 waterproof test, and their performance will not be affected after being immersed in 1 meter of water for 24 hours. We provide global customers with durability test reports and support customized test solutions according to application scenarios to ensure the long-term stable operation of humidifiers, medical nebulizers, hydration meters and other equipment from the source.
