Description

发热板用发热材料
技术领域
本发明涉及锅具技术领域，尤其涉及一种发热板用发热材料。
背景技术
在日常生活中，锅具是人们用来烹煮食物的必备用具。通过锅底的发热板对锅内的食物进行加热，从而将食物制熟。然而，现有的锅具中，发热板通常设置在锅底，因此加热时锅底的食物受热最多，温度最高，而靠近锅盖的食物受热相对较少，温度相对较低，无法保证锅内不同高度的食物的受热均匀性，如果需要使靠近锅盖的食物达到足够的温度，需要加大发热板的加热功率，这就造成能源的浪费。因此，有必要提供一种节能锅，以解决上述问题。
另外，现有的节能锅的发热板用发热材料，主要采用常规合金锻造，发热效率差，且锅内不同部位受热不均。
发明内容
本发明要解决的技术问题是提供一种节能锅，以解决现有的节能锅无法保证锅内不同高度的食物的受热均匀性的问题。同时，本发明还提供了一种发热板用发热材料及其制备方法，与此同时，本发明还提供了一种节能锅的发热板及其制造方法。
为解决上述技术问题，本发明采用的技术方案是：
一种节能锅，包括：外锅、设于所述外锅内部的内锅、设于所述外锅侧部的加热控制器以及设于所述外锅顶部的锅盖；所述外锅内部设有发热板；所述发热板包括位于底部的主发热板和设于所述主发热板上方的数个环状的辅发热板；所述主发热板和辅发热板均与所述加热控制器连接。
所述外锅和锅盖的材质为不锈钢。
发热板用发热材料，由以下重量份的原料制成：
15份氧化锌纤维、5份水玻璃、5份磷酸二氢铝、10份石墨粉、15份硼玻璃、15份糊精、10份粘土、20份5wt％的聚乙烯醇PVA水溶液、5份丹皮酚。
发热板用发热材料的制备方法，步骤如下：
①、将15份氧化锌纤维、5份水玻璃、5份5wt％的聚乙烯醇PVA水溶液加入到球磨机中，球磨5小时；
②、将5份磷酸二氢铝、10份石墨粉、5份5wt％的聚乙烯醇PVA水溶液加入到球磨机中，球磨5小时；
③、将15份硼玻璃、15份糊精、5份5wt％的聚乙烯醇PVA水溶液加入到球磨机中，球磨5小时；
④、将10份粘土、5份5wt％的聚乙烯醇PVA水溶液、5份丹皮酚加入到球磨机中，球磨10小时，得到发热板用发热材料。
节能锅的发热板，包括位于底部的主发热板和设于所述主发热板上方的数个环状的辅发热板；主发热板和辅发热板均采用发热板用发热材料制成。
节能锅的发热板的制造方法，步骤如下：
①模压成型：将发热板用发热材料依照主发热板和辅发热板的规格所需的物料称重后分别置入相应的模具中，将料摊均刮平，移入液压机中对模具进行40Mpa加压，保压时间3秒，卸模得到坯料；
②烘干：将坯料置于恒温炉中于150℃条件下烘干3小时；
③烧结：将烘干的坯料装入烧结炉中，以100℃/h的升温速率加热至1000℃，保持1小时，然后以200℃/h的降温速率降至常温，得到节能锅的主发热板和辅发热板。
本发明所具有的优点与效果是：
1)、本发明的一种节能锅，包括：外锅、设于所述外锅内部的内锅、设于所述外锅侧部的加热控制器以及设于所述外锅顶部的锅盖；所述外锅内部设有发热板；所述发热板包括位于底部的主发热板和设于所述主发热板上方的数个环状的辅发热板；所述主发热板和辅发热板均与所述加热控制器连接；加热时，可根据食物的高度，通过加热控制器控制主发热板和相应的辅发热板进行加热，从而保证锅内不同高度的食物的受热均匀性较好，节省能耗。
2)、发热板用发热材料及其制备方法，通过合理选择原料组分及配比，使制成的发热材料，具有良好的颗粒分散性，从而使最终制成的发热板的传热均匀性能得到较大程度的提升。
3)、节能锅的发热板及其制造方法，通过合理设计发热板的结构，并采用科学的制造方法，从而显著提升发热板及节能锅的节能性能。
