中文摘要 | 本研究係利用奧迪實驗 (Oddy test),針對博物館或美術館在收藏或展示時經常使用的板類材料進行測試,試驗材料為5種市售常用之木質板料,包含有合板、OSB板、纖維板、木心板及粒片板,每種板料分別選擇兩個不同廠牌之製品,以評估常用之木質板料對文物潛藏的危害性,提供國內博物館或美術館在收藏或展示時,選擇材料之參考。 木質材料會逸散揮發有機氣體 (Volatile Organic Compounds) 、半揮發性有機氣體 (Semi-VOCs),而這些揮發性的氣體可能對各類文物造成不同程度的傷害。以Oddy test作為評估文物劣化相關性的測試,具有易辨識(由目測即可判斷腐蝕狀況)、迅速(實驗流程共28天)、簡易、不用特殊設備、不需專業人才等優點,適合應用於一般文物典藏單位作為保存材料選擇之參考。 實驗結果顯示,所有選用之試材對於試驗用之銅片及鉛片,皆有腐蝕之現象產生。故合板、OSB板、纖維版、木心板及粒片板等人造木板,由於內含有機酸等侵蝕性物質,皆不建議作為博物館典藏或展示用材的選擇。在銀、銅、鉛片上各發現不同種類、程度的鏽蝕,銀片的鏽蝕顏色為淡褐色,鏽蝕物可能為氯化物造成之腐蝕,表面生成氯化銀。銅片的鏽蝕為黑色,鏽蝕可能種類為氧化銅、鹼式氯化銅。鉛片的鏽蝕為白色及棕色變色,鏽蝕物可能為碳酸鹽薄層,而有機酸之醋酸、鞣酸、單寧酸會加速其腐蝕反應。 依據各試樣的腐蝕情況發現,大陸產合板對金屬片之腐蝕現象似乎較為輕微,但經檢視發現,其合板品質不佳,膠合層有明顯欠膠狀況,這可能是造成腐蝕狀況較不明顯的原因。此外大陸產合板之蕊材可能採用針葉樹材,致使金屬片上有樹脂附著現象產生。 以下為各金屬試片受不同板料腐蝕程度之比較: Ag:A2>B2>B1>E2>C1=C2=D1=D2 =E1>A1=Blank Cu:B1>A2>E1>E2>C2>C1>D2>A1>B2>D1>Blank Pb:C2>C1>A2>A1>B1>B2>D2>E1>D1>E2>Blank |
英文摘要 | The Oddy test was used to evaluate shelf materials commonly used in museums or art galleries for storing or displaying objects. The tested materials were five commonly used board materials: plywood, OSB board, fiberboard, wooden center board and strand granular piece board. Two brand names of each type of board were chosen and the potential danger to antiques and objects from board materials was evaluated. The results of this study can be used as a reference in choosing materials for the purpose of storage or exhibition in museums and art galleries. Wooden materials emit volatile organic compounds (VOCs) and semi-VOCs. These can cause differing degrees of harm to objects. The Oddy test is a measure of object deterioration. It includes easily distinguishable features (corrosion that can be judged with the naked eye), rapid results (the experimental process takes a total of 28 days) and simple methods without the need for special equipment or professional personnel. The results showed that all of the tested materials cause corrosion to copper or lead. Therefore, man-made plywood, OSB board, fiberboard, wooden center board and strand board are not recommended for storage or exhibition purposes. We found corrosion of different types and degrees for silver and copper. Corroded silver was light brown in color, thus the corrosion could possibly be caused by chloride, forming silver chloride on the surface. The corroded copper was black, most likely due to oxidation. Corroded lead was white and a modified brown, possibly caused by a thin layer of carbonate salt. Organic acids such as acetic acid, tannin and tannic acid accelerate the corrosive reaction. The following is a comparison of metal corrosion levels caused by different board materials: Ag: A2>B2>B1>E2>C1=C2=D1=D2 =E1>A1=Blank Cu: B1>A2>E1>E2>C2>C1>D2>A1>B2>D1>Blank Pb: C2>C1>A2>A1>B1>B2>D2>E1>D1>E2>Blank |
