Fire resistance of wood impregnated with soluble alkaline silicates
(Hindawi Publishing Corporation, 2007-12-02)
The aim of this paper is to determine the fire performance of wood panels (Araucaria angustifolia) impregnated with soluble alkaline silicates. Commercial silicates based on sodium and potassium with 2.5/1.0 and 3.0/1.0 ...
Fire retardant impregnants for woods based on alkaline silicates
(Elsevier, 2008-12-02)
The aim of this paper was to determine the fire performance of wood panels (Araucaria angustifolia) impregnated in a pressure vessel with post-cured alkaline silicates (water glasses). Several commercial silicates based ...
Zinc borates as flame-retardant pigments in chlorine-containing coatings
(Elsevier Science Sa, 2001-06)
This paper discusses the influence of zinc borates with molecular formulas of 2ZnO·3B2O3·3.5H2O and 2ZnO·3B2O3·7.5H2O used for substituting antimony trioxide on the performance of chlorinated alkyd, flame-retardant coatings. ...
Hybrid intumescent coatings for wood protection against fire action
(American Chemical Society, 2011-11)
Hybrid intumescent coatings for wood protection against fire were developed. Several resins were chosen as film-forming materials. Similar active and complementary pigments were used. To improve the efficiency, coatings ...
Siloxanes synthesized “in situ” by sol–gel process for fire control in wood of Araucaria angustifolia
(Elsevier, 2013-10)
Panels of Araucaria angustifolia were chemically modified with alkoxysilanes, hydrolyzed and condensed “in situ” by the sol–gel process. Alkoxysilanes selected were aminopropyl methyldiethoxysilane (A), aminopropyl ...
Nano lithium silicates as flame-retardant impregnants for Pinus radiata
(Sage Publications Ltd, 2011-09)
Aqueous solutions of nano lithium silicates with 5.5/1.0 and 7.5/1.0 silica/alkali molar ratios were used to impregnate Pinus radiata. To obtain these impregnants, a solution of 3.5/1.0 SiO2/Li2O molar ratio was used; this ...
Influência do microclima nas trocas gasosas e na produção de estacas em jardim clonal de eucalyptus spp. e corymbia spp.
(Universidade Estadual Paulista (Unesp), 2019-06-12)
Os avanços no setor florestal foram impulsionados, especialmente, pelos plantios com espécies do gênero Eucalyptus, tornando os viveiros florestais a base deste processo produtivo. Com o aumento da demanda por madeira se ...
Descripción cadavérica de la técnica de reconstrucción del ligamento interóseo talo calcáneo subtalar por artroscopia
(Universidad Nacional de ColombiaBogotá - Medicina - Especialidad en Ortopedia y TraumatologíaDepartamento de CirugíaFacultad de MedicinaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022-02-02)
INTRODUCCION: La inestabilidad de la articulación subtalar (IAS) es una entidad que en muchos casos es subdiagnosticada, sin embargo, es una condición común que ocurre aproximadamente en un cuarto de los casos de inestabilidad ...
Efectos dinámicos en la emisión óptica de sistemas cavidad-qubit en el régimen de acoplamiento ultrafuerte
(Bogotá - Ciencias - Maestría en Ciencias - FísicaDepartamento de FísicaUniversidad Nacional de Colombia - Sede Bogotá, 2020)
Recent experimental developments achieved in cavity-qubit systems in circuit quantum electrodynamics, open the door to enhance quantum properties for the implementation of new emerging quantum architectures. Among these ...
On the use of random sets in geotechnical engineering
(Universidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - GeotecniaDepartamento de Ingeniería Civil y AgrícolaFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2021-10)
Geotechnics is subject to two major types of uncertainty: aleatory and epistemic. Aleatory uncertainty refers to the inherent variability of materials and their external agents, while epistemic uncertainty refers to the ...
