Medical Microporous Atomized Plate

Adapting to Different Atomization Media Characteristics

The characteristics of atomization media (such as water, aromatherapy oils, and cleaning fluids) vary significantly in different scenarios, requiring piezoelectric ceramic atomizers to exhibit strong compatibility. For pure water atomization in humidifier atomizers, customers demanded that the atomizer material be resistant to water corrosion. High-purity piezoelectric ceramic (purity ≥99.5%) and non-porous (porosity ≤0.1%) were used to prevent material degradation caused by long-term exposure to pure water (degradation rate ≤0.01%/year). Furthermore, the atomizer electrodes were nickel-plated (nickel layer thickness ≥5μm), achieving a water resistance rating of Class 9 (no signs of corrosion) according to the ISO 2812-4 standard, ensuring a service life of ≥5000 hours. In the aromatherapy essential oil atomization scenario linked to an aromatherapy diffuser sensor, the customer required the atomizer to be oil-resistant and anti-clogging. The surface was coated with (coating thickness 0.05-0.1μm), which ensured no swelling (swelling rate ≤ 0.5%) or dissolution (dissolution amount ≤ 0.001mg/cm²) upon contact with essential oils (such as lavender and lemon). Furthermore, the atomizer's atomization holes had a diameter of 0.1-0.2mm and smooth pore walls (roughness Ra ≤ 0.1μm) to prevent clogging caused by essential oil residue (clogging rate ≤ 0.05%/week). The regular cleaning reminder function of the aromatherapy diffuser sensor (e.g., every 10 hours of use) further reduced the risk of clogging. For the window cleaner atomizer, the customer required the atomizer to be resistant to acid and alkali corrosion and compatible with cleaning fluids with a pH range of 2-12 (such as acidic descaling agents and alkaline glass cleaners). This atomizer is made of lead zirconate titanate piezoelectric ceramic (PZT-4 model), which meets ASTM G31 Class 1 (non-corrosive) acid and alkali resistance standards. Furthermore, the atomizer seal is made of fluororubber (resistant to cleaning fluid corrosion, with an expansion rate of ≤2%) to prevent cleaning fluid from leaking into the atomizer (leakage rate ≤0.01%). This ensures that atomization performance remains unchanged (atomization volume deviation ≤±2%) even after long-term immersion in cleaning fluid (immersion time ≥100 hours).
