【摘要】：玻璃因其強度高,光學性能優(yōu)良,不易老化,外表光滑等優(yōu)點,廣泛應用于人們的日常生活中,有令人矚目的發(fā)展前景。但由于玻璃表面較高的反射率,往往對人體造成傷害,也就是人們常說的“光污染”。本論文通過化學蒙砂法對玻璃表面進行蒙砂處理,在調(diào)節(jié)透光率的基礎上,增加玻璃的粗糙度,降低反射率,從而達到防止光污染的目的。本論文對蒙砂玻璃的研制是以鈉鈣玻璃為研究對象,以氫氟酸腐蝕玻璃為反應機理,在傳統(tǒng)玻璃蒙砂技術的基礎上,開發(fā)出環(huán)保型蒙砂技術。實驗分別從三部分內(nèi)容進行展開,第一步是以復配玻璃清洗液為前提,玻璃表面的清潔程度直接影響蒙砂效果,將氫氧化鈉、十二烷基苯磺酸鈉、甜菜堿、硬脂酸鈉、磷酸、乙醇、水按不同的比例混合,對玻璃進行清洗,用掃描電鏡觀察玻璃表面形貌,從而確定清洗液的最佳配比,并進行單因素實驗,分別對溫度、時間進行優(yōu)化選擇,確定了最佳工藝條件;第二步探索設計蒙砂液的配方,通過單因素實驗與正交試驗優(yōu)化實驗配比,進而確定最佳工藝條件,并進一步對蒙砂效果進行表征與評估,確定優(yōu)化產(chǎn)品;第三步玻璃蒙砂技術主要應用在環(huán)保型蒙砂技術的開發(fā)及電子顯示屏研究的基礎上,對影響蒙砂效果的因素作出分析,并在后期進行手機屏幕的應用實驗,對蒙砂后的應用效果作出了評估。實驗的研究結(jié)果具體如下:(1)通過研究玻璃清洗液配方與清洗后表面形貌的關系以及工藝條件的影響,確定了清洗液最佳配方為(質(zhì)量比):氫氧化鈉:十二烷基苯磺酸鈉:甜菜堿:硬脂酸鈉:磷酸:乙醇:水=6:1.5:0.5:0.8:3.0:2.5:95,最佳工藝條件為:在50℃的溫度下,清洗10min。(2)設計正交試驗及單因素實驗對蒙砂液的配方進行優(yōu)化,確定最佳配比(質(zhì)量比)為氟化鈉:鹽酸:硫酸銨:硫酸鋇:淀粉:水=21:12:2:1:1.5:300,以蒙砂液的最佳配比為基礎,通過單因素實驗,得出最佳工藝條件:在溫度為30℃水浴下加熱,蒙砂3min。(3)在最佳配比及工藝條件下進行蒙砂操作,并對玻璃蒙砂效果進行SEM、EDX、UV及粗糙度的表征,結(jié)果表明:玻璃的透光率降低到85%,粗糙度提升至0.35~0.40um之間,蒙砂后玻璃表面結(jié)晶均勻、光滑度及透光性較蒙砂前有了明顯的改善。(4)進行了蒙砂技術在手機面板上的應用實驗,對蒙砂的應用效果進行了AFM、粗糙度、透光性的檢測分析,結(jié)果表明:蒙砂后手機面板的表面形貌、透光性及光滑度較之前要好。在強光照射下,手機面板的成像能力及清晰度明顯提高,有效地減少了靜疲勞,降低了光對人體的輻射。
[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，
