Description

除霜除雾ITO玻璃基板的制备方法
技术领域
本发明涉及真空阴极磁控溅射镀膜领域,特别是涉及一种除霜除雾ITO玻璃基板的制备方法。
背景技术
当玻璃制品在遇到较大的温湿度变化时,就容易产生雾面,不仅为使用者带来不便,而且对于电器中的玻璃制品,若其表面结雾会严重影响电器的电气性能,例如常用家电冰箱,如果冰箱用的玻璃出现结雾,会影响冰箱内的水果食物等的新鲜,更严重的会造成食物的腐坏,对人体健康造成威胁;其次,霜是热的不良导体,覆盖在蒸发器表面,成为蒸发器与箱内食物之间的隔热层,影响蒸发器与箱内食物之间的热交换,使箱内温度降不下来,降低冰箱的制冷性能,增加耗电量,甚至使压缩机长时间运行而发热、烧坏。另外,霜中存有各种食品的气味,长时间不除霜,会使冰箱发出异味。一般情况下,霜层达5毫米厚时,就应除去。
目前通常使用两种方法自动地除去电器玻璃上的雾水,第一种是热风除霜除雾,具体而言就是在电器靠近玻璃的地方开设出风孔,在展示台下方安装风扇,利用出风孔中的风带动热气流动,加热玻璃,从而消除霜和雾气;但是这种方法的局限在于不能保证整块玻璃都能被加热,一般不能消除玻璃的上半部分的雾气。第二种是电热丝加热除霜除雾,即在双层玻璃之间嵌入电阻丝,这种方法的除霜除雾效果好,但是夹在双层玻璃内的电阻丝会留下黑色的丝线,影响可见性。
因此亟需提供一种新型的冰箱用除霜除雾玻璃的制备方法来解决上述问题。
发明内容
本发明所要解决的技术问题是提供一种冰箱用除霜除雾ITO玻璃基板的制备方法,能够达到较好地除霜除雾效果。
为解决上述技术问题,本发明采用的一个技术方案是:提供一种除霜除雾ITO玻璃基板的制备方法,包括以下步骤:
(1)准备玻璃基材,并对其进行切割、清洗;
(2)采用磁控溅射镀膜方式在所述玻璃基材的表面镀入导电膜,其中导电膜包括SiO2及其上的ITO膜;
(3)在所述导电膜膜面四周丝印两条导电银浆,并固化;
(4)在所述导电膜玻璃的两端分别印上金属电极;
(5)再在导电银浆层的表面附着一层玻璃板。
在本发明一个较佳实施例中,所述除霜除雾ITO玻璃基板的可视透过率大于等于玻璃基材透过率的83%,所述除霜除雾ITO玻璃基板镀上导电膜后不影响玻璃的可视透过率,其可视透过率由SiO2的膜厚决定。
由本发明所述制备方法制得的ITO玻璃基板根据客户所需的功率要求,不同的电器表面所需玻璃面积不同,因而其产生的功率也不同,下面为已知电阻、玻璃面积等条件下所述除雾除霜ITO玻璃基板所需功率的具体计算方法。
计算过程运用的公式如下:
Q=P*t=cm*Δt;m=ρ*hs
其中,Q为热量;t为冰箱运行的时间;c为导电银浆比热容;△t为温度变化量;
m为导电银浆的质量,可通过导电银浆的密度和体积算出。
本发明的有益效果是:
(1)通过在导电膜玻璃与玻璃板之间设置导电银浆,其与外界密封,保证该导电银浆层干燥、不出现雾气;当ITO导电膜通电后,导电银浆产生的热量可加热玻璃板,进而消除玻璃板和导电膜玻璃表面的雾气;
(2)导电膜玻璃的面积可以覆盖整块玻璃板,因而可以消除整块玻璃板表面的雾气,不会留下除霜除雾的死角,视觉效果好;
(3)ITO导电膜本身无毒,安全卫生,用于某些电器例如冰箱时不会影响食品的品质;
(4)导电银浆相较于ITO成本低,与ITO薄膜间有极好的附着性,且具有导电性使之发热,对电器玻璃的除霜除雾有很好的控制效果。
附图说明
图1是本发明所述除霜除雾ITO玻璃基板一较佳实施例的正视图;
图2是本发明所述除霜除雾ITO玻璃基板另一较佳实施例的正视图;
图3是所述除霜除雾ITO玻璃基板的侧视图;

功率: P = U 2 R ,
方块电阻: R = ρ L S , R = ρ V S 2 = ρL 2 V .
当P=30W时,
