THE DEGRADATION MECHANISMS OF SOUND RECORDING
The lifespan of a plastic is largely determined at the manufacturing stage. Variables such as basic resin, the materials added to the basic resin to alter its properties, the lamination of materials with dissimilar properties, and the manufacturing process itself, all directly affect the lifespan of the plastic. Post-manufacture environmental factors such as storage conditions, temperature, humidity, and handling also contribute to the long-term stability of the plastics.
Plastics can be divided into two main classes, thermoplastic and thermosetting. Thermoplastics soften and flow when heated and are normally shaped by heat and pressure. They will soften and flow again when re-heated. Vinyl, used in the manufacturing of LP's, is a thermoplastic.
Acetate Discs
Prior to the advent of magnetic tape, instantaneous recordings were made chiefly on acetate discs. The chemical makeup of these discs, therefore, had to be a compromise between ease of engraving and the quality of the recording that resulted.
Since the 1930s, most blank acetate discs have been manufactured with a base, usually aluminum (although glass was used during the war years and cardboard for inexpensive home recordings), that was coated with nitrocellulose lacquer plasticized with castor oil. Because of the lacquer's inherent properties, acetate discs are the least stable type of sound recording.
Continuous Shrinkage of the lacquer coating due to the loss of the castor oil plasticizer is the primary destructive force. The gradual loss of plasticizer causes progressive embrittlement and the irreversible loss of sound information. Because the coating is bonded to a core which cannot shrink, internal stresses result, which in turn cause cracking and peeling of the coating.
Nitrocellulose acetate decomposes continuously and over time reacts with water vapour or oxygen to produce acids that act as a catalyst for several other chemical reactions. As with most chemical reactions, these reactions are accelerated with elevated temperature and humidity levels.
Vulcanite (early Berliner records) Vulcanite (hard rubber) was the first material used commercially by Berliner and provided the necessary basis for the exploitation of the flat disc.
In 1839 Hancock in England and Goodyear in the US independently discovered vulcanization. Vulcanization is the process of treating crude rubber with sulfur or sulfur compounds in varying proportions and at different temperatures. The result is an increase in the rubber's strength and elasticity, yielding either soft rubber or vulcanite. Vulcanite has been used to make combs, buttons, jewels, fountain pens, musical instruments, etc.
Vulcanite is stable in the dark and retains its appearance and properties very well. In response to light and/or heat the material loses sulfur then becomes brittle and loses its shine. Light induces oxidation of the rubber and forms oxides of sulfur and sulfuric acid in the presence of humidity. The acidity builds up to a level at which the degrading plastic is attacked and eventually decomposes1. The degradation can be demonstrated when playing an afflicted Berliner. The surface of the disc is shaved off by the pressure of the stylus against the groove wall.
Vulcanite also posed problems in the production of discs. The uneven shrinkage during cooling caused severe warping; entrapped gas would produce blisters; hard particles create loud pops and clicks; and the coarseness of the Vulcanite structure produced terrible background noise.
Shellac Discs
The first shellac discs date form the early 1900s. Shellac is a composite word--it's a combination of shell and lac. The word is a Hindus name of an insect that infests certain types of trees. The lac draws sap from these trees, processes it through its digestive system and secretes it so that it becomes an attached protective shell around its body. Thus the shell is generally smaller than a grain of rice. Harvest involved scraping off the encrusted shells from twigs and branches.
After WWII resins such as Vinsol, Valite, Vynil chloride acetate and other commercial resins replaced organic shellac as the main binder. These plastics are slightly more stable than organic type discs. It is often difficult to distinguish between shellac and shellac type discs by inspection. Determining the causes of shellac disc degradation is rather difficult because a very wide range of qualities of shellac and "fillers" have been used by manufacturers. Therefore one cannot expect consistent behavior of all stored shellac discs. The disc properties are as much a function of the filler as they are of the cementing agent. The fillers used run the gamut of natural cellulosic materials as well as of minerals.
The average shellac content in these "shellac" discs is approximately 15% shellac.
Also, record manufacturers would introduce scrap as filler into new mixtures. The manufacturers would recycle returned, unsold shellac discs. It was not uncommon for the scrap to included soft drink bottles litter, pieces of masonry or other unwanted material, all of which were ground up together and mixed in with the next batch of compound.4
Columbia discs (laminated disc)
In 1906 Columbia introduced the Marconi Velvet Tone developed by Giulemino Marconi. The manufacturing technique involved using a craft paper core cut to approximate record size. After the core was carefully flattened and dried, it was covered with a powdered shellac compound of a thin uniform thickness. The dust-coated core was put in an oven and the dust fused to the core. For two-sided records, the operation was repeated for the other side.5
The advantage of this construction was that the amount of surface material needed to carry the music grooves could be kept very small. This economy allowed the use the best plastic available at that time. Edison was to use this idea in 1912/13, in the manufacturing of his Diamond Disc.
In 1922 Columbia returned to the laminated record, this time with a coarser compound for the powder core that was bonded between two discs of craft paper.
In general shellac discs are relatively stable. The curing process of shellac during disc manufacturing generates a chemical reaction where certain simple molecules such as water or ammonia molecules are eliminated. Curing causes shellac to shrink, increasing its density and its brittleness. This condensation continues at a much slower rate after disc manufacturing. The speed at which condensation occurred is a function of storage temperature, storage humidity and completeness of cure. (The condensation reaction reduces the potential concentration of reacting elements. A semi-quantitative measure of the cure of shellac is its solubility in alcohol. Raw shellac is totally soluble in alcohol and completely cured shellac is insoluble, and the extent to which condensation has proceeded determines the degree of solubility of a shellac.6) Thus the condensation becomes the primary degenerative force. The internal reaction of the material and the rate at which the reaction occurs are related to storage temperature, storage humidity (moisture increases the condensation reaction rate) and completeness of the cured shellac.
Storage stability of these fillers vary widely. Organic materials in the aggregates are susceptible to fungus attack, while shellac itself is resistant to fungus attack.
In a proper storage environment, these discs suffer a slow, progressive embrittlement of the shellac. This embrittlement causes a fine powder to be shed from the disc after each playback. The behaviour of the other aggregate components is unpredictable, due to the wide combinations and variety of materials (and of material quality) that were used.
Edison Diamond disc
The Edison Diamond disc has the distinction of having been made of the first completely synthetic plastic, a material called phenol (phenol was also used in the manufacture of Bakelite).
The Edison diamond disc is a laminated disc made up of a thick core and a thin varnish layers covering each of its sides.
The Ό" core, which is also know as a powder blank, was manufactured by compressing the following ingredients in the following proportions:7 Wood flour
58%
Modified ethyl alcohol (AKA ethynol)
26%
Phenol formaldehyde (AKA Bakelite)
15%
Lampblack (the pigment)
1% The varnish, named Edison condensite varnish was
made-up of Modified ethyl alcohol
55%
Phenol formaldehyde (63% phenol + 37% formaldehyde)
38%
Other, including "Shino", used to promote a gloss finish
7%
The varnish would be applied to the blank by a brush as the blank rotated slowly. Four applications or coats were given each blank face with a drying period between. After the last coat the varnished blank would be placed in a steam-heated oven. This completed the drying and also effected a partial reaction of the varnish ingredients
Prior to pressing, the blanks would be heated before applying pressure to soften. After the pressure was applied the heat was left on to complete the curing or reaction of the varnish. Then the moulds were cooled and the pressure released.
Prolonged contact with moisture or severe changes in humidity may cause damage to the surface through moisture absorption. In general Phenol is very stable and presents no serious degradation problems, neither is it prone to attack by bacteria, fungi or insects although, occasionally, under humid conditions moulds may grow and cause some surface attack on a nutrient filler such as wood or cotton, or be supported by a nutrient contaminant on the surface.
Vinyl Discs
Thus far, vinyl has proven to be the most stable of the materials that have been used in the manufacture of sound recordings.8 However, although stable, its life is not indefinite. Pickett and Lemcoe, in Preservation and Storage of Sound Recordings, states that "failure by chemical degradation of a vinyl disc in ordinary library environments should not occur in less than a century".
Vinyl discs are made of polyvinyl chloride (PVC) and a small percentage (usually less than 25 percent) of "fillers", stabilizer, pigment, anti-static substances, etc. Internal plasticization, through a copolymerizing of vinyl acetate with vinyl chloride, is needed to achieve the required properties for the desired application.
Polyvinyl chloride degrades chemically when exposed to ultraviolet light or to heat. Phonograph discs are exposed to high temperatures during moulding and pressing. Unless stopped, this heat would be a catalyst for ongoing dehydrochlorination, which is the release of hydrochloric acid (HCl) from the PVC as a result of thermo-degradation. Stabilization is therefore achieved by adding a chemical to the resin during manufacture. This does not prevent the degradation but controls it, mainly by consuming the free HCl. Sufficient effective stabilizer remains in a plastic phonograph disc to protect it for several decades after pressing.

Cleaning
Since dust is usually held in place by electrostatic attraction, dry wiping on its own does not work effectively. The added friction created by the duster will cause the dust to jump back to the charged surface.
Distilled water is used for cleaning records and CDs for many reasons. Its precise chemical makeup is known, it will not leave any residue behind, is safe to use, and is inexpensive. Water disperses static charges and counteracts the increase in conductivity from the pick-up of salt deposits from finger prints. However, water alone cannot dissolve grease, thus surfactants are used as additives to enable water to be a grease solvent. Surfactants break grease surface bonds and allow water to penetrate grease solids, causing swelling and then random dispersion.
General
The Canadian Conservation Institute (CCI) recommends the use of nonionic, ethelyne oxide condensates surfactants to clean sound recordings. The CCI does not foresee long-term problems associated with the use of nonionic surfactants such as Tergitol. Tergitol 15-S-3 is an oil soluble surfactant and 15-S-9 is a water soluble surfactant. Combined they remove a wide range of dirt and greases and can safely be used on sound recordings. Use 0.25 part of Tergitol 15-S-3 and 0.25 parts of Tergitol 15-S-9 per 100 parts of distilled water. (These products are available in small quantities from TALAS (Division of Technical Library Service Inc) 213 West 35th Street, New York, N.Y. (212) 465-8722.) The recording must then be rinsed thoroughly with distilled water to eliminate any trace of detergent residue.
Keep an airgun handy to blow off light surface dust.
Grooved discs
Grooved discs are best cleaned using a record cleaning machine such as the Keith Monks, VPI, Nitty Gritty using 0.25 part of Tergitol 15-S-3 and 0.25 parts of Tergitol 15-S-9 per 100 parts of distilled water. These machines allow for an even dispersion of fluid and can then vacuum the liquid leaving a clean, dry surface. The discs must then be rinsed thoroughly with distilled water and vacuumed dry to eliminate any trace of detergent residue. Records should be cleaned before each playback. Clean Vulcanite discs showing signs of acid build up using 0.25 part of Tergitol 15-S-3 and 0.25 parts of Tergitol 15-S-9 per 100 parts of distilled water and rinse thoroughly.
Clean acetate discs showing signs of palmitic acid deposits (white greasy substance on acetate disc surface) as if cleaning LPs, except add 1 part ammonia per 100 to the Tergitol cleaning solution. Do not use ammonia on shellac based discs.
Tapes
Vacuum reel-to-reel tape pack if dusty. Use a vacuum which has a hose, and keep the motor away from the tape in order to reduce the risk of magnetizing the tapes.
Clean tape surfaces using a product such as 3M "Tape Cleaning Fabric" (610-1-150). This soft fabric product will pick-up loose debris commonly found on tape surfaces after being dislodged by the fabric fibers.
CDs
An air gun should be used to blow off any light surface dust.
If fingerprints or other stains must be removed, 0.25 part of Tergitol 15-S-3 and 0.25 parts of Tergitol 15-S-9 per 100 parts of distilled water can be utilized safely. Carefully blot the area of the disc needing washing with a soft cloth (preferably a soft cotton that has been washed several times) imbued with a concentration of Tergitol and distilled water. Rinse well using a second cloth soaked in distilled water. Blot dry using a soft cotton cloth. Use an airgun to blow off any lint left over.
Avoid rubbing in any direction.

ΤΟ ΠΛΥΣΙΜΟ ΤΩΝ ΔΙΣΚΩΝ ΤΟΥΣ ΔΙΑΤΗΡΕΙ ΣΕ ΚΑΛΗ ΚΑΤΑΣΤΑΣΗ ΚΑΙ ΦΡΟΝΤΙΖΕΙ ΤΗ ΒΕΛΟΝΑ ΜΑΣ.ΩΣΤΟΣΟ ΚΑΛΟ ΕΙΝΑΙ ΝΑ ΧΡΗΣΙΜΟΠΟΙΟΥΜΕ ΞΗΡΑ ΚΑΘΑΡΙΣΤΙΚΑ ΓΙΑ ΤΗ ΒΕΛΟΝΑ ΜΑΣ.

Καμιά φορά υπάρχουν βρωμιές που ξεκολλάνε μόνο με υγρό βουρτσάκι. Το θέμα είναι να βάζουμε πολύ λίγο γιατί από προηγούμενες βελόνες έχω την εμπειρία της σκλήρυνσης της ανάρτησης από αυτά τα υγρά. Πρέπει να νοτίζεται μόνο η ακίδα.

Βασιζεται στον συνδιασμο ισοπροπυλικη αλκοολη και πανακι απο μικροινες. Ενα παλιο πικαπ χρησιμοποιειται σαν πλατω. Ο δισκος καθαριζεται πρωτα με το βουρτσακι απο ινες ανθρακα για να φυγουν οι σκονες. Στη συνεχεια βρεχουμε ολη την επιφανεια του δισκου με ενα μειγμα ισοπροπυλικης αλκοολης και αποσταγμενου νερου 3/1 και με μια πολυ μικρη ποσοτητα /μια σταγονα υγρο για καθαρισμα πιατων. Ο συγγραφεας ισχυριζεται πως ετσι ολες οι ακαθαρσιες φευγουν απο τα αυλακια του δισκου και βρισκονται στο υγρο. Με ενα πανακι μικροινων ντυλιγμενο π.χ. σε ενα κομματι ξυλο τριβουμε τωρα την επιφανεια του δισκου. Με το ενα χερι γυριζουμετον δισκο πιανοντας τον βεβαια στην ακρη, με το αλλο κραταμε το αυστοσχεδιο βουρτσακι κανοντας κινησεις μπρος/πισω. Στη συνεχεια με ενα δευτερο στεγνο πανακι μικροινων ντυλιγμενο σαν ενα κυλινδρο παιρνουμε ο,τι περισεψε. Το πικαπ ειναι απαραιτητο, αλλα σιγουρα μπορει να κατασκευαστει οτιδιποτε αλλο παρομοιο πλατω. Ελπιζω να εγινα κατανοητος, τα ελληνικα μου ειναι μετα απο 27 ετη στη Γερμανια παναθλια.

Μια χαρά είναι τα Ελληνικά σου.
Καλως ήρθες στην παρέα.
Αυτό που με προβληματίζει με τη μέθοδο αυτή είναι η ποιότητα του πανιού. Έχω 4-5 πανάκια με μικροϊνες, όλα τους διαφορετικά!
