【摘要】：玻璃因其强度高,光学性能优良,不易老化,外表光滑等优点,广泛应用于人们的日常生活中,有令人瞩目的发展前景。但由于玻璃表面较高的反射率,往往对人体造成伤害,也就是人们常说的“光污染”。本论文通过化学蒙砂法对玻璃表面进行蒙砂处理,在调节透光率的基础上,增加玻璃的粗糙度,降低反射率,从而达到防止光污染的目的。本论文对蒙砂玻璃的研制是以钠钙玻璃为研究对象,以氢氟酸腐蚀玻璃为反应机理,在传统玻璃蒙砂技术的基础上,开发出环保型蒙砂技术。实验分别从三部分内容进行展开,第一步是以复配玻璃清洗液为前提,玻璃表面的清洁程度直接影响蒙砂效果,将氢氧化钠、十二烷基苯磺酸钠、甜菜碱、硬脂酸钠、磷酸、乙醇、水按不同的比例混合,对玻璃进行清洗,用扫描电镜观察玻璃表面形貌,从而确定清洗液的最佳配比,并进行单因素实验,分别对温度、时间进行优化选择,确定了最佳工艺条件;第二步探索设计蒙砂液的配方,通过单因素实验与正交试验优化实验配比,进而确定最佳工艺条件,并进一步对蒙砂效果进行表征与评估,确定优化产品;第三步玻璃蒙砂技术主要应用在环保型蒙砂技术的开发及电子显示屏研究的基础上,对影响蒙砂效果的因素作出分析,并在后期进行手机屏幕的应用实验,对蒙砂后的应用效果作出了评估。实验的研究结果具体如下:(1)通过研究玻璃清洗液配方与清洗后表面形貌的关系以及工艺条件的影响,确定了清洗液最佳配方为(质量比):氢氧化钠:十二烷基苯磺酸钠:甜菜碱:硬脂酸钠:磷酸:乙醇:水=6:1.5:0.5:0.8:3.0:2.5:95,最佳工艺条件为:在50℃的温度下,清洗10min。(2)设计正交试验及单因素实验对蒙砂液的配方进行优化,确定最佳配比(质量比)为氟化钠:盐酸:硫酸铵:硫酸钡:淀粉:水=21:12:2:1:1.5:300,以蒙砂液的最佳配比为基础,通过单因素实验,得出最佳工艺条件:在温度为30℃水浴下加热,蒙砂3min。(3)在最佳配比及工艺条件下进行蒙砂操作,并对玻璃蒙砂效果进行SEM、EDX、UV及粗糙度的表征,结果表明:玻璃的透光率降低到85%,粗糙度提升至0.35~0.40um之间,蒙砂后玻璃表面结晶均匀、光滑度及透光性较蒙砂前有了明显的改善。(4)进行了蒙砂技术在手机面板上的应用实验,对蒙砂的应用效果进行了AFM、粗糙度、透光性的检测分析,结果表明:蒙砂后手机面板的表面形貌、透光性及光滑度较之前要好。在强光照射下,手机面板的成像能力及清晰度明显提高,有效地减少了静疲劳,降低了光对人体的辐射。
[Abstract]:Glass is widely used in people's daily life because of its high strength, excellent optical properties, hard aging, smooth appearance and so on. However, because of the high reflectivity of glass surface, it often causes harm to human body, which is often referred to as "light pollution". In this paper, the surface of glass is sanded by chemical masking method. On the basis of adjusting the transmittance, the roughness of glass is increased and the reflectivity is reduced, so as to prevent light pollution. In this paper, the preparation of montmorillonite glass is to take sodium calcium glass as research object and hydrofluoric acid corroded glass as reaction mechanism, on the basis of traditional glass-coated technology, the environment-friendly coated sand technology has been developed. The experiment was carried out from three parts respectively. The first step was to take the compound glass cleaning liquid as the premise. The cleaning degree of the glass surface directly affected the sand effect. Sodium hydroxide, sodium dodecylbenzene sulfonate, betaine, sodium stearate, phosphoric acid, sodium hydroxide, sodium dodecyl benzene sulfonate, sodium betaine, sodium stearate, phosphoric acid, The glass was cleaned by ethanol and water in different proportion. The surface morphology of the glass was observed by scanning electron microscope, and the optimum proportion of the cleaning liquid was determined. The single factor experiment was carried out, and the temperature and time were optimized, respectively. The optimum technological conditions were determined. The second step is to explore and design the formula of Mongolian sand liquid, optimize the ratio of single factor experiment and orthogonal experiment, and then determine the best technological conditions, and further characterize and evaluate the effect of the sand cover, and determine the optimized product. The third step is mainly used in the development of environmentally friendly sand masking technology and the research of electronic display screen. The factors that affect the effect of coated sand are analyzed, and the application experiment of mobile phone screen is carried out in the later stage. The application effect of Mongolian sand was evaluated. The results of the experiment are as follows: (1) the relationship between the formula of glass cleaning liquid and the surface morphology after cleaning and the influence of process conditions are studied. The optimum formula of cleaning solution was determined as follows: sodium hydroxide: sodium dodecylbenzene sulfonate: betaine: sodium stearate: phosphoric acid: ethanol: water = 6: 1.5: 0.5: 0.8: 3.0: 2.5: 95, The optimum technological conditions are as follows: cleaning at 50 鈩，
