摘 要
本試驗研究的對象是松香-明礬酸性上膠紙,針對其耐久性不佳,提出預
防和補強的措施。經嘗試鹼溶液、壓締、裱貼等三種脫酸方法後,以紙張
加速劣化後之物理性質評估脫酸的效果。
試驗結果顯示:鹼性紙較酸性紙有緩和老化之效果;但在墨色的表現上,
若調整類似酸性紙之上膠度,則AKD上膠紙可以替代酸性紙之用途。但無
添加碳酸鈣之AKD上膠紙,其老化速度類似於酸性紙。
酸性紙和膠彩畫紙經飽和氫氧化鈣、0.1%氫氧化鈉、0.1%氫氧化鋇之鹼溶
液處理後都有緩和老化之功效,但以0.1%氫氧化鈉處理之紙力略有減退;
而膠彩畫紙若沒有經過脫酸處理,即使在無濕氣的劣化條件下,其物理性
質衰退相當快。
從三種鹼液處理過之紙試樣發現,除了氫氧化鋇外都會嚴重影響顏色和畫
面的表現,特別是氫氧化鈣,肉眼即可清楚發現殘留在膠彩畫作上,但對
顏料之影響則無。
酸性紙經鹼性紙的壓締處理可提升pH 值,壓締條件在高濕高壓下可縮短
壓締的時間,達到弱鹼性,以壓締處理5 、10 、15天後之老化性質與壓
締時間成正比。處理過的酸性紙經老化400 小時後,需要再壓締以維持其
穩定。
酸性紙裱貼鹼性紙後,以含碳酸鈣之裱褙紙裱貼者,有明顯的提昇pH 值
,故有緩和老化之效益;而無碳酸鈣貼者略遜,且老化至後期有如未處理
之酸性紙的衰退。

Summary
It is well known that acidic papers are easily deteriorated due
to acid hydrolysis of carbohydrates.
The purpose of this study is intended to prevent the aging of
rosin-alum sized paper from deteriorating.
Three kinds of the deacidification of paper such as immersing ,
press , mounting were carried out in the study.
The physical properties of accelerated aging of papers to
determine effect of the deacidification were evaluated.
The experimental results were summarized as follows:
1. Acidic paper shows poor permanence than that of alkaline
paper. In case of the similar sizing for both of acidic and AKD
sized paper,it is likely that in good quality of ink-color
paper on surface. Moreover , without the addition of CaCO3 in
AKD sized paper , which might have poor permanence as the
acidic paper does.
2.By immersing in saturated Ca(OH)2 solution , 0.1%NaOH ,
0.1%Ba(OH)2 solutions , paper deterioration can be reduced ,
but showed slight decrease in paper strength at 0.1%NaOH-
treatment aged
paper .Without the deacidification of gel-color paper , the
physical properties will fall off rapidly even in moisture free
condition .
3.Three kinds of immersing solution except Ba(OH)2 solution , the color
and appearance of gel-color specimen after immersing in Ca(OH)2 and
NaOH solution are remarkably affected . The painting surface were also
destroyed by Ca(OH)2,but this treatment did not deteriorate the pigments.
However , the treatments is not interfere with pigment.
2. Using pressure treatment provide pH value of change acidic
paper , high stress and humid condition would reduce pressure
time to achieve paper with weak alkalinity . Aging properties
of 5 , 10, 15 days for pressure samples direct interrelation to
pressure time . After aging 400 hrs for treated paper must
pressure again to moderate decomposition .
3. Acidic paper mounted by alkaline paper would moderate the aging of
paper , and can achieve paper higher pH value .However , mounted by
neutral paper without CaCO3 would be somewhat inferior . Paper quality
with hold aging of is similar to untreated paper .
