Amplificari instaurabo senem paper- [N-methylol acrylamide XCVIII%]
Charta, ut pelagus carrier chartam culturalis reliquias, est thesaurus humanae civilization, hæreditque et recording historia, culturae et spiritualis civilization de Seres gentem.In recent years, due to disrepair, natural aging, moth-eaten mildew, a large number of paper has appeared serious acidification, aging, yellowing brittle and even comminuted phenomenon.The protection and restoration of paper cultural relics with paper as the carrier has been paid attention to, but the restoration of paper from the root is less, it is difficult to really extend its service life.Existing conservation and restoration work mainly Focuses in Diacidification processus, et relative pauci studiis in supplementum. In existentium supplementum reparatione modi potest causa damnum ad chartam structuram, aut mutare in macroscopic morphologia de chartam, aut accelerate senescit in chartam, et confidunt in manual, potest non esse massa supplementum.
According to the aging mechanism of paper and the main factors affecting the strength of paper, combined with the current situation of aging paper and the requirements for the restoration of paper cultural relics,Ultrasonic atomization method is used to transport the atomized micron grade reinforcing agent to the inside of the paper at a very low speed, to ensure that the paper slowly and fully absorb the reinforcing agent, as far as possible to avoid the deformation of the paper, and can be propter massa supplementi repair.n-hydroxymethylacrylamide sicut chartam enhancer est monomer cum bonam aquam solubility et eget reactivity.through incrucem-vinculumINDIGNON-methylol acrylamide Et chartam fibra et sui auto-crosslinking polymerization products replete spatium inter chartam fibris, amplio vinculum vires inter chartam fibris, et realize confirmare instauratione chartam.
NMAwas used in the strengthening repair of electrostatic copy paper by ultrasonic atomization method, and the influence of atomization absorption, enhancer concentration, atomization rate and drying temperature on the strengthening effect of electrostatic copy paper was explored.And the changes of macroscopic morphology, microscopic surface structure, surface element content and internal chemical groups of the paper before and after reinforcement.
Macroscopic morphologia de charta non mutare significantly post auctus restitutio, quae verificatur quodNMAcould successfully realize the enhanced restoration of paper without causing secondary damage, so it can be used for the enhanced restoration of precious ancient books such as aging paper.After artificial aging, the physical properties of N-hydroxymethyl acrylamide enhanced paper are better than those of untreated paper, especially the tensile index and tearing index have more stable performance;The analysis of infrared spectrum shows that In proprietate iuga hydrogenii vinculum sunt stabilis in senescentis processus of roboravit repairet charta. Praeter NMA protegit vinculum inter charta fibris ad quaedam quatenus.
