Scale crystal invasion
When calcium-containing tap water (hardness > 150mg/L) is repeatedly heated and formed, β-CaCO₃ crystals will form on the bottom plate support at a rate of 3μm/month. Our factory confirmed that a 0.1mm thick scale layer caused a 68% drop in thermal conductivity, resulting in a 12-second delay in steam output. Even more dangerous is that these rhombohedrons scratch the coating, with corrosion lightning reaching a depth of 25μm.
Level 3 Deep Cleaning Technique
▶ Physical peeling layer (for mild scaling)
After the bottom plate cools down to 50℃, wipe it with ultra-fine aluminum oxide abrasive paste (Mohs hardness 7.5) in a circular motion. Focus on cleaning the 3mm area around the steam jet hole - the scale here accounts for 82% of the total. The titanium alloy scraper provided by our factory has been tested and verified 4000 times, and the scraping force is controlled within 0.6N to avoid damaging the nano-plating.
▶ Chemical dissolution layer (against stubborn crystals)
Soak cotton pads in citric acid solution (concentration 8%±0.5%) and apply to the base plate. The acid needs to react on the surface at 60℃ for 15 minutes, at which time the scale dissolution rate reaches its peak. It is strictly forbidden to use acetic acid! Its strong permeability will corrode the coating joints. Although the corrosion resistance of our patented honeycomb coating structure is increased by 5 times, it is still difficult to resist long-term acid corrosion.
▶ Energy regeneration layer (repairing microscopic damage)
After cleaning, turn on the power to the medium temperature (about 110℃), and apply it evenly with a Teflon repair stick at a speed of 2cm/s. The molten repair agent will fill the scratches ≤20μm, restore the surface energy to 72mN/m (standard value for new plates), and increase the uniformity of steam diffusion to 93%.
Military-grade protection system
Prevention is better than cure: The magnetized water purification module innovatively developed by our factory changes the crystallization path of calcium ions through a 3000 Gauss magnetic field, so that 90% of the scale forms suspended particles and is ejected with steam. After 2000 hours of testing, the wear rate of the bottom plate coating using this technology is only 1/7 of that of conventional models.
Deadly operation restricted area
× Do not poke the steam spray hole with a needle - 99% of the blockage is actually due to internal valve body failure. Violent unblocking will cause the aperture to deform ±0.2mm and the steam scattering angle to be out of control
× Do not wipe the high-temperature base with a wet cloth - when the temperature difference exceeds 80℃, the quenching effect will induce micro cracks in the coating, shortening the thermal fatigue life by 60%
× Refuse to polish with steel balls - a single wipe will cause scratches up to 15μm deep, exceeding 1/3 of the total thickness of the coating
Every maintenance is a redemption of thermal energy efficiency. When you see the steam gushing evenly again, it is actually a microscopic victory for trillions of water molecules to regain free passage. Remember: a clean base is the soul of the iron.
