Evaluation of coatings used for prolonging the durability of cross-laminated timber against weathering and wood decay fungiS Bobadilha, Gabrielly 01 May 2020 (has links)
The aim of this study was to assess the durability of commercially available coatings on cross- laminated timber (CLT) during natural and artificial weathering and against wood decay fungus. The CLT samples coated with twelve coatings were tested based on their moisture exclusion, water repellency, volumetric swelling and anti-swelling efficiency. Among all the tested coatings, only five (A, C, F, I and J) were able to promote water repellency and limiting dimensional changes. The top five coatings were then tested on CLT blocks exposed to natural (Starkville-MS and Madison-WI) and artificial weathering conditions and brown-rot fungi (G. trabeum). Variables such as visual ratings, water uptake, color and gloss change were determined during both weathering procedures. Damage caused by Gloeophyllum trabeum on uncoated and coated CLT was analyzed based on visual appearance and weight loss. For the coatings C and F, the visual rakings and color change results indicated high consistency during outdoor exposure. The artificial weathering showed that coating C and F were the most resistant to chalking, lightness, color and gloss change. In the soil block test, coating C obtained satisfactory performance against G. trabeum with weight loss of 1.33%. Coatings F and J did not offer any protection to water penetration, which eventually contributed to fungal development. For future, new coatings specifically designed for the protection of high percentages of end-grain in CLT panels should be a target of research and development.

Polymeric interactions in tablet coating filmsSakellariou, P. January 1984 (has links)
The objective of this work was the investigation of the polymeric interactions in tablet coating films in relation with effective film formulations. The polymeric interactions were studied by means of torsional braid analysis. For this purpose an existing torsional braid analyser was improved and successfully interfaced to a microprocessor for data acquisition and reduction. Discussion on the contribution of the substrate to the thermomechanical spectra of the TBA as well as factors associated with the optimisation of the technique are presented. The dynamic mechanical behaviour of EC, HPMC, HPMCP-HP50, HPMCP-HP55, HPC and CAP film formers was studied with particular attention to structure- Tg relationship. The plasticisation of two of the most common film formers, namely EC and HPMC, with a series of polyethylene glycols was investigated. It was shown that PEGs efficiently plasticise HPMC, whereas they exhibited limited interactions with EC. The relation of the plasticising efficiency to the size and concentration of the PEGs with respect to the optimisation of the tablet coating formulation is also discussed. The thermomechanical behaviour of blends of EC with water-/pH-dependent film formers was also studied with TBA, in conjunction with the requirements for controlled release coatings. All polyblends exhibited phase separation and the required domain morphology, which was shown capable of retaining small amounts of water-/pH-dependent components even after prolonged leaching. Moreover, the modification of the thermomechanical performance of 80/20 w/w EC/HPMC blends plasticised with PEG200 and PEG400 was investigated. These studies indicated diffusion of the plasticisers into both phases. Finally, the effects of blend composition and interactions in terms of efficient sustained release coatings are identified and discussed.
