常见问题解答
01. Product & Quality Assurance
你们的保温杯是什么材质的？它们符合食品级安全标准吗？
我们的保温杯内胆采用食品级304不锈钢（标准款）或316不锈钢（高端款），外壳采用食品级PP材料或食品接触级不锈钢。所有材料均通过了FDA（美国）、LFGB（德国）和SGS等国际权威食品级安全认证，无毒、无味、耐腐蚀，可直接接触饮料，安全有保障。
保温杯的保温时间和保冷时间分别是多少？测试条件是什么？
在标准测试条件下（室温25℃，无阳光直射）：普通保温杯可保温12小时（水温≥60℃），保冷24小时（水温≤10℃）；高端真空保温杯可保温长达24小时，保冷长达48小时。实际使用时间可能因环境温度、饮料初始温度、开盖频率等因素略有不同。

06. Technical & Manufacturing Details
Q: What is the difference between 304 and 316 stainless steel for your bottles?
While both are food-grade, 304 stainless steel is the industry standard for daily use due to its excellent durability and cost-effectiveness. 316 stainless steel contains molybdenum, providing superior resistance to chlorides and salt spray, making it the ideal choice for high-end medical-grade products or extreme outdoor environments.
Q: How do you handle "Sweat-Proof" and condensation issues?
All our vacuum-insulated products feature a sophisticated double-wall structure with a high-vacuum interlayer. This technology ensures the exterior remains bone-dry (Sweat-Proof), regardless of how cold the beverage inside is, protecting your hands and furniture.
