Definitions
- the present invention relates to a new chemical composition based on a suspension of hydroxyapatite nanoparticles (HA) in carboxymethyl-cellulose (CMC) in alcoholic solution (isopropylic alcohol), used for paper deacidification, by acidity anihilation from 4.5 to 7.2.
- HA hydroxyapatite nanoparticles
- CMC carboxymethyl-cellulose
- alcoholic solution isopropylic alcohol
- the paper degradation due to an excessive acidity (due to chemical or biological action), is reflected by the yellow tonalities appearance accompanied by an increased brittlement of the paper, which is transformed into a very fragile substance that is destroyed at the slightest touch.
- the acid hydrolysis of cellulose that occurs during aging represents about 95% of the paper damages, and is considered as the most significant cause of deterioration of cellulosic materials.
- Acid attack causes a random attack on hemi-acetal bonds between different constituents of cellulose molecules. This reaction will weaken the molecules, leading to the brittlement of cellulosic materials.
- HA hydroxyapatite
- CMC carboxymethyl-cellulose
- HA carboxymethyl-cellulose
- CMC carboxymethyl-cellulose
- HA hidroxyapatite
- HA has hydrogen atoms bound to oxygen atom.
- the functional groups that contain pairs of positive charged ions of calcium and clusters of six atoms of oxygen negative charge associated with phosphate crystal triplets, generating hexagonal crystals with a columnar shape with Ca: P 1.67.
- the ions Ca, P and hydroxyl groups, are located on the HA surface.
- the two components of the composition HA are interacting only by weak hydrogen bonds.
- the interaction between CMC with HA in this composition is visible in FTIR spectra through the widening of OH group bands (3500-3000 cm -1 ).
- the electrostatic binding of the two components will be favored, too, forasmuch due to acidic pH, Ca 2+ ions located on the surface of HA come into contact with the -COO 2- anions from the CMC surface.
- the electrostatic link between these two components is stabilizing and neutralizing the paper pH where it is sprayed (visible at 1460 cm -1 band of the FTIR spectrum, attributed to ionic pair -Ca 2+ COO 2- ).
- the atmospheric CO 2 has the ability to react with none of these two components, the risk of transformation of pH paper from the basic range to acidic one, is practically null.
- composition hidroxyapatite carboxymethyl cellulose prepared by us, has the following advantages:
- Example 1 Operations have been carried out by the treatment of a yellowed, lightened and brittled paper sample:
