中文摘要 |
本實驗提出一種新穎氯化銀薄膜製作方式,利用鹽酸水溶液與硝酸銀固體反應析出沉澱,形成氯化銀薄膜Type I。在氯化銀薄膜Type I實驗過程中,利用10M、7M與4M三種不同濃度鹽酸水溶液進行反應,隨著反應時間增加,薄膜上表面由長條狀演變為片狀晶形,下表面棒狀結構的形成以及薄膜剖面結構因過冷度影響使晶形由等軸狀變為柱狀;藉由對照組:鹽酸固體與硝酸銀水溶液析出氯化銀薄膜Type II和硝酸銀固體與氯化鈉水溶液析出氯化銀薄膜Type III實驗得知,氯化銀薄膜接觸鹽酸水溶液之表面,會因為氫離子影響而形成片狀結構;而氯化銀薄膜接觸硝酸銀水溶液之表面,則會使氯化銀小晶粒堆積成棒狀結構。 應用上,氯化銀與空氣清淨機濾網做結合,將氯化銀沉積於不織布,並觀察在不同鹽酸濃度下,顆粒會隨濃度降低而變小。在10M與4M鹽酸濃度下,反應出氯化銀晶體則呈現六面體,在7M鹽酸濃度下,氯化銀顆粒為長條狀結構。 |
英文摘要 |
This study has proposed a novel method of silver chloride film Type I by mixing liquid hydrogen chloride and silver nitrate. The experiment was procedured with three kinds of Hydrogen Chloride solution concentration:10M, 4M, and 4M, and we discussed the effect of difference Hydrogen Chloride concentration of 10M, 7M, and 4M on the structure of the film. The top surface morphology of silver chloride crystal transformed from long strip to tabular shape with increasing reaction time. The bottom surface formed stick, and transformed from equiaxed to columnar by supercooling in structure of cross section with increasing reaction time. Compared with the experimental results which precipitated AgCl film Type II by mixing liquid silver nitrate and solid hydrogen chloride and AgCl film Type III by mixing liquid sodium chloride and solid silver nitrate:the morphology of surface of silver chloride which contacting hydrogen chloride formed tabular shape by effecting of hydrogen ion, and the morphology of surface of silver chloride which contacting liquid silver nitrate heaped stick by crystal of silver chloride. In the application, silver chloride was precipitated to unwoven cloth to combine with filter of air conditioner. We observed the particle size became smaller with lower concentration in of Hydrogen Chloride. The morphology of silver chloride crystal in 10M and 4M concentration of Hydrogen Chloride was hexahedron, and long strip crystal in 7M concentration of Hydrogen Chloride. |
