Material Characteristics Analysis Of Ceramic Glazed Hair Straighteners And Curling Irons
Date:
In the hair styling tool market, ceramic glaze technology has become the mainstream coating solution for curler straightener 2 in 1. This surface treatment process solidifies ceramic materials onto a metal heating plate through high-temperature sintering, forming a smooth and uniform glaze layer.
Physical properties of ceramic glaze
The thickness of best flat iron curling iron ceramic glaze is typically between 50-100 micrometers, and its surface roughness Ra value can be controlled below 0.2 micrometers. This ultra-smooth characteristic significantly reduces the coefficient of friction when hair strands slide on the heating plate, minimizing mechanical damage to the hair cuticle. The glaze material itself possesses good thermal stability, with an operating temperature range covering 80℃ to 230℃ and a temperature distribution uniformity deviation of less than ±5℃.
The heat generated by the PTC or MCH heating element inside the heating plate of the mini hair curler and straightener is conducted to the ceramic layer through the metal substrate, and the thermal conductivity of the glaze is about 2-3 W/(m·K). This value is between that of metal and ordinary ceramic, allowing for rapid temperature rise in response to temperature control commands without causing hair damage due to localized overheating. The glaze layer also possesses chemical corrosion resistance; everyday hair care products, styling sprays, and other chemicals will not corrode the coating.
best curling iron and straightener in one Surface Coating Durability Performance
After repeated use, the adhesion and integrity of the ceramic glaze directly affect the styling effect. The high-quality curling iron comb glaze achieves a bonding strength of over 15MPa with the substrate, reaching a grade 0 adhesion level in the cross-cut adhesion test. Under long-term high-temperature operating environments, the glaze will not crack or peel, and its service life can exceed 3000 hours. The bekind apex 2 in 1 hair straightener surface hardness reaches Mohs 6-7, making it resistant to scratches during daily cleaning and storage.
