Abstract
Većina dokumenata iz 19. i 20. st. pisana je na kiselom papiru jer se tada u proizvodnji papira počinje koristiti drvenjača. Stoga je propadanje papira uzrokovano kiselinama čest problem s kojim se susreću konzervatori i restauratori odgovorni za očuvanje papirne građe. Papir se uglavnom sastoji od celuloze, hemiceluloze i lignina, ali i dodataka kao što su ljepila, punila i bojila koja mogu pridonijeti njegovoj kiselosti. U radu je opisana struktura celuloze te način na koji kiseline utječu na njezinu degradaciju što rezultira kraćim vlaknima. Kiselost i propadanje papira uzrokovano je brojnim faktorima kao što su kisela hidroliza, oksidacija, utjecaj svjetlosti i temperature, onečišćeni zrak te djelovanje bioloških organizama. Kiseli papir vremenom žuti, postaje krhak te mu je smanjena fleksibilnost. Mjerenjem pH vrijednosti može se saznati kolika je kiselost ili lužnatost papirnog nosioca. To je jedna od najčešćih analiza korištenih u konzervaciji i restauraciji papira i njome se dobiva uvid u stanje predmeta. Kako bi se usporilo propadanje dokumenata iz 19. i 20.st. pisanih na kiselom papiru provodi se masovna neutralizacija. Istraživanja su pokazala učinkovitost ove metode te je ona pridonijela produljenju trajnosti papira.
Abstract (english)
Most of documents from the 19th and the 20th centuries were written on the acidic paper, since it was during that period that pulp started to be used in the papermaking process. This is why paper deterioration due to acidity is a common problem for conservators in the care of paper materials. Paper is mainly composed of cellulose, hemicellulose and lignin, but it also contains other additives such as glue, fillers and pigments which can further contribute to its acidity. This paper describes the chemical structure of cellulose and the way acids influence its degradation which results in shorter fibers. Paper acidity and deterioration is caused by numerous factors such as acid hydrolysis, oxidation, exposure to light and temperature, air pollution and the presence of microorganisms. Over time, acidic paper becomes more brittle and yellow and loses its flexibility. By estimating the pH of paper it is possible to determine its acidity or alkalinity. It is one of the most frequently used analyses in the conservation and restoration of paper which gives insight into the overall condition of an object. In order to retard the decay of documents of the 19th and 20th centuries written on acidic paper, the materials were treated by the mass deacidification processes. The research confirmed the effectiveness of this method and it has proved to have a great role in extending the durability of paper.
