Ceramic coated cup: 316L/304 stainless steel substrate+nano ceramic coating. Taking into account good insulation, lightweight, no cross flavor, and high cost-effectiveness, it is the preferred choice for daily tea, coffee, and juice; Shortcoming: The coating is afraid of being scratched by hard objects and cannot be cleaned with steel wire balls.
Identify the material
True ceramic coating: The coating is delicate and uniform, without particles or exposed substrate; Distinguish between full ceramic (without metal substrate, heavier) and ordinary stainless steel (with metallic smell, prone to tea stains). Prioritize 316L substrate for stronger acid and alkali resistance.
Required safety criteria
Food grade nano ceramic coating, in compliance with GB 4806 national standard; The inner wall is coated with pure white and free of impurities, without color painting or inferior spraying. It is resistant to high temperatures, does not peel off, and has no odor.
Structure and insulation
Double layer vacuum structure, with insulation performance consistent with ordinary stainless steel cups (6h ≥ 70 ℃); Food grade detachable silicone ring, inverted leak proof, easy to clean without dead corners.
Capacity recommendation
Universal commuting: 450 to 500ml; outdoor large capacity: 600 to 700ml; lightweight portable: 350ml.
Avoiding pitfalls and maintenance points
Avoiding pitfalls: low-priced rough coatings, peeling bubbles, and inferior 304 substrates. Maintenance: Do not use steel wire balls or hard brushes. Simply rinse with a soft cloth to avoid dry burning and direct sunlight.
