纸质文物的耐久性不仅与组成材料有关,还受其外部环境的影响。酸性使纤维素发生降解,纸张发黄变脆,最终导致纸质文物自毁现象的发生。适宜的温湿度条件不仅能避免纸质文物的弯曲变形,还能有效防止虫害和霉菌的滋生,空气净化系统能在很大程度上减少污染物对文物的危害。 Durability of paper artifacts not only related to the composition of materials, but also by the external environment. Acidic degradation of cellulose, paper yellowing brittle, eventually leading to the occurrence of paper artifacts destructive. Appropriate conditions of temperature and humidity can not only avoid the bending deformation of paper artifacts, but also effectively prevent the breeding of pests and molds. Air purification system can greatly reduce the harm of pollutants to cultural relics.
