Backsheets : from conception to finished products / Michelle Ostiguy in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 19, N° 4 (04/2012)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 19, N° 4 (04/2012) . - p. 22-25 Titre : Backsheets : from conception to finished products : Films and adhesives can play a critical role in the general construction and performance of solar modules Type de document : texte imprimé Auteurs : Michelle Ostiguy, Auteur Année de publication : 2012 Article en page(s) : p. 22-25 Langues : Américain (ame) Catégories : Certification Colles:Adhésifs Couches minces Couches minces multicouches Essais (technologie) Fluoropolymères Photopiles Revêtements multicouches Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Mention solar panels or solar arrays to the average citizen, and thoughts of long, sunny days and moderate to high temperatures might enter their mind. Perhaps some might even envision a semi-tropical locale with gentle breezes wafting by. Most (if not all) solar panel installers wish that type of location was the reality. In truth, however, while sunlight is the prime factor in placing solar panels in order to maximize their usefulness as energy receptors, solar installation sites are not always warm and comfortable. In many instances, solar installations are positioned in harsh climates and difficult locations. Because of this, all the non-solar-cell components have to be tested and found able to withstand conditions ranging from deep frosts to extreme heat, as well as high winds, ice, snow, sleet, rain, and any other type of potentially damaging moisture—even debris impingement. The various elements that make up the finished module must prove to be consistently able to perform, whether in an industrial array or for consumer use.

Recycling pressure-sensitive products in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 19, N° 4 (04/2012)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 19, N° 4 (04/2012) . - p. 28-36 Titre : Recycling pressure-sensitive products : One approach for reducing the impact of PSAs on recycling operations is to redesign label systems to inhibit fragmentation of adhesive films Type de document : texte imprimé Année de publication : 2012 Article en page(s) : p. 28-36 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Adhésifs -- Recyclage Adhésifs sensibles à la pression Adhésifs thermofusibles Labels Index. décimale : 668.3 Adhésifs et produits semblables Résumé : The efficient control of contaminants such as metals, plastics, inks and adhesives during the processing of recovered paper products determines the profitability of recycling mills. In fact, it is arguably the most important technical obstacle in expanding the use of recycled paper.1-4 An especially challenging category of contaminants to manage is pressure-sensitive adhesive (PSA). PSAs are soft elastomer-based materials that are highly viscous and sticky to the touch. In recovered paper, they are usually found as part of pressure-sensitive (PS) label systems, consisting of facestock coated with a 0.7-1.0 mil layer of PSA. During the initial stages of the paper recycling process, the bonds between fibers are broken using water and mechanical energy. This operation, known as repulping, also fragments adhesive films. Much of the removal of these fragments in the recycling process occurs at the pressure screens and is governed mainly by the size and shape of the residual adhesive. The PSA that is not removed by screening is introduced into the remaining fiber recovery operations and the papermaking process, where it can significantly diminish production efficiency and product quality. A widely acknowledged approach to reduce the negative impact of PSA on paper recycling is to design adhesives for enhanced removal early in the recycling process. Given the high efficiency of particle removal demonstrated by screening operations, the most promising PSAs are those designed to generate larger residual particles. Our recent research efforts have focused on developing guidelines for producing these types of PS products. This article includes the rationale for our test methods to gauge screening removal efficiencies, the identification of properties controlling the fragmentation of both hot-melt and water-based PSAs, and a discussion of the role additives and laminate design play in determining the fragmentation behavior of adhesive films.
