Il peut être incorporé au produit durant sa fabrication ou appliqué ultérieurement à sa surface. Intumescence (chimie) Liants Pentanedione Phosphates Polymères ignifuges Polyols Index. décimale : 667.9 Revêtements et enduits Résumé : Fire retardant intumescent coatings based on pentanediono complex of chromium, phosphates, amides, polyols, amino and acrylic binders have been developed for poly vinyl chloride insulated power cables. The fire performance of developed coatings has been assessed by employing international standard procedures. The cables coated with such coating showed significant improvement in circuit failure time in power cable. Developed coating was also found effective in reducing rate and amount of smoke in the event of fire. During exposure, the coating swelled to form spongy, cellular insulating foam which acts as an effective barrier against the conduction of heat to the surface and to the core of electric cable specimen.

Conductive coatings for plastics / Minal Mangesh Mayekar in PAINTINDIA, Vol. LXIII, N° 8 (08/2013)

[article]  inPAINTINDIA > Vol. LXIII, N° 8 (08/2013) . - p. 57-62 Titre : Conductive coatings for plastics Type de document : texte imprimé Auteurs : Minal Mangesh Mayekar, Auteur Année de publication : 2013 Article en page(s) : p. 57-62 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Conducteurs organiques Matières plastiques -- Revêtement:Matières plastiques -- Peinture Matières plastiques dans les automobiles Noir de carbone Pigments inorganiques Revêtement conducteur Revêtements poudre:Peinture poudre Index. décimale : 667.9 Revêtements et enduits Résumé : In automotive industries metal parts are replaced by plastic due to its light weight, flexibility of design and lower cost. To increase productivity and to reduce process time electrostatic painting is preferred by automotive manufacturers. Metal substrates can be easily painted by this technique. But electrostatic painting of plastic is difficult since plastics are usually insulators and therefore cannot be adequately grounded. If the coating is to be applied electrostatically a conductive primer is used to provide a path to the ground. Conductivity is generally achieved by using conductive pigments such as conductive carbon black, graphite fibrils, hydrolyzed antimony-tin oxide and metal powder. In some cases conductive polymers are used for this purpose.

Objective mottling control at the line with new and innovative testing technologies / Gabi Kigle-Böckle in PAINTINDIA, Vol. LXIII, N° 8 (08/2013)

[article]  inPAINTINDIA > Vol. LXIII, N° 8 (08/2013) . - p. 63-66 Titre : Objective mottling control at the line with new and innovative testing technologies Type de document : texte imprimé Auteurs : Gabi Kigle-Böckle, Auteur Année de publication : 2013 Article en page(s) : p. 63-66 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Automobiles -- Revêtements:Automobiles -- Peinture Mesure -- Instruments Qualité -- Contrôle Revêtements -- Défauts:Peinture -- Défauts Index. décimale : 667.9 Revêtements et enduits Résumé : Today's quality requirements for automotive finishes in regards to color and appearance are very high as it is proven that "the first impression" establishes lasting perceptual quality opinions extending beyond design and paint appearance. Therefore, the exterior finish of a cara body and its add-on parts should be perfectly matching color and appearance. CONCLUSION : In order to guarantee uniform color and appearance objective measurement tools are needed. The visual inspection of surface finish quality is highly dependent on lightning and viewing conditions which are not always ideal in production environment. A new innovative measurement technology realized in a portable instrument allows objective control of critical paint defects called mottling. Visual field studies were conducted to establish customer relevant limits.

Types of corrosive environment - Part 4 / P. K. Kamani in PAINTINDIA, Vol. LXIII, N° 8 (08/2013)

[article]  inPAINTINDIA > Vol. LXIII, N° 8 (08/2013) . - p. 80-85 Titre : Types of corrosive environment - Part 4 Type de document : texte imprimé Auteurs : P. K. Kamani, Auteur Année de publication : 2013 Article en page(s) : p. 80-85 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Corrosion Index. décimale : 667.9 Revêtements et enduits Résumé : THE discussion of corrosion is incomplete if a combination of material and environment is not taken together. The same material behaves differently in different environment i.e. the corrosivity of environment varies from hour to hour, place to place and season to season. On the other hand, the same environment behaves differently with different metals. In this part a discussion would be made on environment; the material would be discussed in latter part of the series. The environment consists of the entire surrounding in contact with the material. The environment is rich in water and oxygen, which causes corrosion to less resistant metals. The presence of other contaminants, stimulate the corrosion activity even with the noble metals. The primary factors to describe the environment are: (a) physical state-gas, liquid, or solid; (b) chemical composition-constituents and concentrations; and (c) temperature. Other factors can be important in specific cases e.g. relative velocity of a solution (flow or agitation), mechanical loads on the material etc. The nature and rate of atmospheric corrosion is more or less dependent on the composition and properties of the thin-film surface electrolyte. The temperature, time of wetness and the type of concentration of gaseous and particulate pollutants in the atmosphere largely affect the corrosion attack. Any atmospheric condition should be defined in terms of temperature, humidity and contaminants or its corrosivity quantified in relation to the materials of interest ( e.g. steel, zinc, aluminium, copper and their alloys ).

Corrosion in above ground storage tanks and its control / N. J. Paul in PAINTINDIA, Vol. LXIII, N° 8 (08/2013)

[article]  inPAINTINDIA > Vol. LXIII, N° 8 (08/2013) . - p. 86-90 Titre : Corrosion in above ground storage tanks and its control Type de document : texte imprimé Auteurs : N. J. Paul, Auteur ; Buddhadeb Duari, Auteur ; Abdul Jalil Khoory, Auteur Année de publication : 2013 Article en page(s) : p. 86-90 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Anticorrosion Corrosion Protection cathodique Réservoirs (récipients) -- revêtements protecteurs Index. décimale : 667.9 Revêtements et enduits Résumé : Potable water for the city of Abu Dhabi in the United Arab Emirates is obtained by desalination of sea water. There are several power and desalination stations distributed all over the country. The largest of them is located in Umm Al Nar which has a 90 MGPD output and the storage is made in above ground steel tanks coated inside and outside. Besides these there are several smaller tanks for storing fire water, distillate, fuel oil etc. for the boilers and turbines. The soif on which they are located is notable for its salinity and the sub soit water level is very close to grade. Most of the tanks have been made more than ten to fifteen years ago and therefore were not provided with cathodic protection for the external of tank bottom. The corrosion has therefore set in at the annular ring plate and propagating to the centre. The rehabiIitation of some of the tanks has been done at very great cost and the newer larger tanks are provided with cathodic protection of better design. This paper deals with some of these aspects.
