acid-free paper (<paper by composition or origin>, paper (fiber product), ... Materials (hierarchy name)) |
|
Note: Paper that contains no free acids, thus providing greater permanence and durability; the term does not necessarily imply that the paper is alkaline-buffered. Acid-free paper is typically produced from cotton linters, rags, esparto grass, or chemical wood pulp which minimizes the potential for acid and/or lignin in the pulp. Acid-free paper may also contain a buffering material to maintain a pH in the neutral to slightly alkaline range. This helps scavenge any acidic materials formed by bleaching residues, sizes, degradation products, or air pollutants.

Additional Notes: |
|
| Chinese (traditional) ..... 為不含游離酸的紙張，保存時間更長久，且更耐用；該詞條不見得是指經過鹼性中和的紙。去酸紙的原料通常為棉短絨、碎布、北非茅草，或化學木漿，以減少紙漿酸化和/或產生木質素的可能。去酸紙也可能含有中和物質，將酸鹼度維持在中和偏鹼的範圍內，有助於清除任何因為漂白殘留、漿料、降解產物或空氣污染物所產生之酸性物質。 |
