Description

石墨锅具的表面处理工艺和石墨锅具 技术领域
本发明涉及家用电器及喷涂技术领域，具体而言，涉及一种石墨锅具的表面处理工艺和一种石墨锅具。
背景技术
目前，石墨作为一种健康环保材料，同时具有良好的导热及导磁特性，是一种优秀的煮食器皿材料。其中，石墨是由碳原子组成的，而生命的基本单元氨基酸、核苷酸也是以碳元素做骨架变化而来的，可以说，没有碳就没有生命，因此，石墨虽然看上去黑黑的，却是生命世界里最纯净的材料，对人体具有很好的改善和保健作用：(1)石墨制品经过加热后能释放远红外线，而远红外线能够增强机体功能，使人体充满生机和活力，并有效预防各种疾病，如：令水分子活化，提高身体含氧量，使人头脑灵活，精神振奋；增强新陈代谢，调整神经液机体；有效预防糖尿病、高血脂、肥胖症、痛风等由于新陈代谢紊乱引起的疾病；改善血液循环，特别是微循环系统；可有效预防因微循环系统紊乱引起的高血压、心血管疾病、肿瘤、关节炎、四肢冰冷麻痹等疾病；美白养颜，消炎、消肿功能；提高人体免疫功能，调节血液的酸碱平衡、淡化烟酒，强化肝脏功能等功效。(2)石墨制品具有很好的吸附性，具体地，碳的空隙结构使碳具有很好的吸附性，故碳常被用作吸附材料，用于吸附水分、气味、有毒物质等，实验表明，前几天烤肉用过的石墨烤盘看上去非常干净，但放到电磁炉上加热，会看到上次烤肉时吸附的油脂和有害物质会慢慢渗出，但是，只要用干净的餐纸擦拭干净即可继续使用。(3)石墨制品具有很好的导热性，传热快，受热均匀，节约燃料，所以，用石墨制成的烤盘，锅等加热快，而且烧制的食物受热均匀，从里往外熟，加热时间短，不仅味道纯正，而且能锁住食物本来的养分，实验表明，用石墨烤盘烤肉时，刚 开始电磁炉打到大火，仅20秒-30秒就能预热，开始烤制食物时只要打在小火上即可，有利用节约能源。(4)石墨制品具有化学稳定性和抗侵蚀能力，由于石墨在常温下具有很好的化学稳定性，不受任何强酸，强碱及有机溶剂的侵蚀，因此，石墨制品即使长期使用损耗也很少，只要擦拭干净还如新的一样，且石墨制品环保健康，无放射性污染，耐高温。(5)碳要在2000-3300度高温的环境下经过至少十几个昼夜的石墨化过程才能成为石墨，因此，石墨中的有毒有害物质早已释放殆尽，至少在2000度以内是稳定的。
但是，作为器皿材料往往至少需要耐刮及不粘的特性，因此需要在石墨材质表面进行不粘涂层的喷涂，而采用不粘涂层的喷涂之前，石墨材质表面必须进行喷砂才具有良好的附着力。然而由于石墨硬度比较低，目前喷砂工艺导致石墨材质表面非常粗糙，砂面效果不尽如人意，影响用户的使用体验。
因此，如何改善喷砂工艺，解决现有喷砂工艺中由于石墨硬度较低导致石墨材质表面粗糙的问题，使得石墨表面获得良好的砂面效果，同时确保不粘涂层具有良好的附着力，提升用户的使用体验，成为亟待解决的技术问题。
