低辐射（Low-E）镀膜玻璃膜层的热稳定性对可钢化产品质量影响很大,在Low-E镀膜玻璃的钢化工艺中,由于加热温度过高或加热时间过长,可能会造成一些缺陷,如弯曲,波形,脱膜,色差,麻点等。本文用马弗炉对相同膜系的可钢化单银low-E玻璃进行了不同加热温度、不同保温时间下的耐热实验;通过观察外观变化,测试颜色变化、色差,及其方块电阻、E值、透过率、雾度等随温度和保温时间的变化关系,研究了相同膜系结构的可钢低辐射镀膜玻璃的耐热性能;为产品膜系结构设计,质量风险评估提供参考。
Thermal stability of low-E glass has a great effect on the quality of tempered products.Owning to high temperature or long heating time,defects in low-E glass such as bending,wave-forming,stripping,color differences and pitting may be caused by tempering.Thermal experiments on temperable mono-silver coated low-E glasses were performed under different temperatures and heating times by using a muffle furnace.Variations of appearance,color,color differences,sheet resistance,E value,transmittance and haze with the heating temperature and heating time were observed and tested in order to reveal their relationship.Thermal stability of temperable low-E glass was studied which can offer references for film design and quality risk assessment.
