摘要:
The present invention relates to a liquid-state temporary reinforcing material, a preparation method therefor and an application thereof. The liquid-state temporary reinforcing material comprises a reinforcing material and a crystallization inhibitor; the reinforcing material is selected from molecules of any two or more of menthol, menthone, menthol ester and menthol ether, and the content of the crystallization inhibitor is less than 50 ppm. For the liquid-state temporary reinforcing material of the present invention, the menthol and the derivatives of the liquid-state temporary reinforcing material are integrally mixed together to form the composite material for temporary reinforcing, the composite material being liquid and volatilization-controllable at room temperature. Thus, the temporary reinforcing requirements for extracting cultural relics at an archaeology excavation site may be met, and the material is convenient to use.

Stabilized alkaline composite nanoparticles containing at least a hydroxide or carbonate or organic compound of an alkaline earth metal, have an alkaline core consisting of calcium hydroxide, magnesium hydroxide, magnesium carbonate, calcium carbonate, magnesium bis(hexamethyldisilazide), calcium bis(hexamethyl-disilazide), calcium acetylacetonate hydrate, calcium 2,2,6,6,-tetramethyl-3,5-heptanedionate (Da(TMD) 2 or mixtures thereof and optionally a hydrophilic cellulose derivative and a stabilizing outer layer containing at least a stabilizer selected from the group: silylated hydrophobic polysaccharides, hydrophobic polysaccharides, poly(dimethylsiloxane) diglycidyl ether terminated and poly(dimethylsiloxane)aminopropyl terminated. A method and use of these particles for the simultaneous deacidification and strengthening preservation and protection of cellulose based artefacts are described.
摘要:
This invention relates to a new chemical composition comprising nanoparticles of hydroxyapatite, suspended in solution of carboxymethyl cellulose (50% : 50%) in isopropylic alcohol as solvent, this composition being used for paper deacidification purposes, by the anihilating the paper acidity from pH = 4.5 to alkaline range pH = 7.2.
摘要:
The invention relates to a conditioning agent and to a method for conditioning organic material, especially documents. Said conditioning agent consists substantially of moisture or moist CO2. According to the invention, a deacidification agent, preferably alkaline earth compounds, is added to the gels that are used for the deacidification of the documents to be treated, in order to improve this process.
摘要:
The invention concerns a method for treating paper, in particular a method for deacidifying and reinforcing paper, and for preventing acidfication of paper, and the applications of said method. The treatment method is characterised in that it comprises impregnation of the paper to be treated with a solution containing at least a compound comprising several amine functions and one or more alkoxysilyls or silanes in an organic solvent or a organic solvent/water mixture, and drying the paper. The invention is useful for preserving and restoring old documents of collections or archives, such as books, manuscripts, posters, plans, maps or the like, and for protecting documents against acidification.

摘要:
A paper alkaline conservation process is operated in a fluid container. A sheet of paper requiring treatment is placed within a flat gauze (1) bag whose sides are joined at the periphery (2) by sewing or heat welding. The gauze is made of plastic or rubber-coated plastic. The fluid container is a photographic paper processing machine with a series of rollers which transport the bag through the machine and fluid treatment to a drier.
摘要:
A preservation article for the preservation of an archival article which involves an alkaline buffer and an adsorbent. A method of preserving an archival article which involves providing a preservation article in proximity to an archival article, wherein the preservation article includes an alkaline buffer and an adsorbent. The preservation article may be coated on or incorporated into a container, a packaging material, a support for an archival article or the archival article itself.
