Protection of Timber from Combustion and Burning Using Alkaline Aluminosilicate-Based Coatings

Abstract

The paper presents data on the protection of timber from combustion and burning using the protective coatings based on alkali aluminosilicates. The results of study suggested to formulate a mix design of the alkaline aluminosilicate bond, choose fillers and to determine rates of mass loss of timber at burning and degree to which the samples under study have been deteriorated. The coated samples of wood have a minimum rate of burning – 0.002-0.0024 kg/s·m2, which is 1.3-1.6 times less than the permissible value (0.0032 kg/s·m2) and 1.5-2.3 less than that of the analogue (a commercial product "Siofarb”). In combustibility and burning behavior, the formulated coatings can be classified as hardly combustible and non- burnable materials.

Development of fire resistant coating for the protection of electrical cables of fire in a closed space

“…Application of various polymers in the form of syn thetic resins and their aqueous dispersions as binders of fireresistant coatings allows them to significantly increase their water resistance and adhesion strength, to reduce the mass and thickness of the coatings. However, at the same time, the amount of toxic substances and smoke released during a fire increases, especially when epoxy resins are used in fireresistant coatings [4]. Application of aqueous disper sions of polymers [5] reduces the water resistance of the fireresistant coatings composition.…”

Fire Protection of Wooden Storage Containers for Explosive and Pyrotechnic Products

“…Geocements (TU U V.2.7-16403272.001-97, Ukraine) are a kind of alkali cements, which are environmentally friendly and characterized by high durability due to the synthesis of the structure of substances, analogues of natural zeolites and feldspathoidal. Geocements are fire-and heat-resistant, characterized by low elasticity, under the influence of the temperature factor emit in the environment only water vapour, but require application to the building structure of considerable thickness of the protective layer [6][7][8][9][10][11][12][13][14][15].…”

Improvement of method of determining fireproof properties of coating and wood treatment quality

“…1, зразок деревини при одно-разовому оброблені геоцементним покриттям [7][8][9][10] забезпечує лише ІІ групу вогнезахисту, а при двора-зовому обробленні -I групу вогнезахисту. Суттєвим недоліком такого методу є неможливість визначення якості оброблення на об'єктах будівництва.…”
