In the technology of gluing solid wood, various adhesives are used, which, in addition to ensuring the strength of the gluing, must also be characterized by a number of rheological and colloidal-chemical properties, namely: have acceptable viscosity, low contact angles, have good spreading and enveloping ability, penetrate deep into the wood , providing reliable cohesive-adhesive contact and much more. Today, adhesives based on PVA dispersions and urea formaldehydes are used, the properties of which have been sufficiently studied and tested in practice. An alternative to organic-based adhesives is mineral adhesives, in particular aluminosilicate adhesives, which are non-flammable and have high mechanical strength. Object of research: rheokinetic patterns and processes of formation of colloidal-chemical structures of aluminosilicate adhesives modified with compounds of the ANO3 and ANO3×nH2O type. Investigated problem: Considering that aluminosilicate adhesives are multiphase reactive suspensions, the viscosity of which changes over time and affects their viability, the issue of viscosity stabilization due to the introduction of electrolyte salts into their composition is relevant, and will also contribute to improving the wettability and spreading of the adhesive during applying them to substrates and gluing samples from various types of wood. Main scientific results: The effect of the concentrations of compounds of the ANO3 and ANO3×nH2O type on the rheokinetic and chemical-colloidal properties of the aluminosilicate adhesive has been established, which will make it possible to use aluminosilicate adhesives in practice for gluing wood of various species, as well as to work out possible technological methods of their application, taking into account the obtained data on the viscosity, wetting and spreadability of the modified adhesive on the surface of the wood substrate. Area of practical use of the research results: woodworking enterprises for the production of glued solid wood products. Innovative technological product: aluminosilicate adhesives modified with ANO3 and ANO3×nH2O nitrate additives for gluing wood of various species. Scope of application of an innovative technological product: the application of these approaches will make it possible to obtain glued materials from wood from different species with improved technological and physical and mechanical properties of the glue seam and, accordingly, to increase the quality and reliability of products.

Проведеними дослiдженнями отримано можливiсть виготовлення теплоiзоляцiйних матерiалiв з сухостiйної деревини сосни для облаштування примiщень. Сировиною для їхнього виробництва є деревнi волокна, якi формують у плоскi плити. Встановлено механiзми процесу теплоiзоляцiї при передаваннi енергiї через матерiал, що дає можливiсть впливати на цей процес. Доведено, що процеси теплоiзоляцiї полягають у зниженнi пористостi матерiалу. Так, зi зменшенням об'ємної маси матерiалу, теплопровiднiсть зменшується, i навпаки. Проведено моделювання процесу передавання тепла при спучуваннi вогнезахисного покриття, визначено залежностi теплофiзичних коефiцiєнтiв вiд температури. За отриманими залежностями розраховано коефiцiєнт теплопровiдностi для виробiв з сухостiйної деревини сосни, який сягає 0,132 Вт/(м•K). У разi оброблення виробiв з деревини клейовою композицiєю зменшується до 0,121 Вт/(м•K), а при створеннi теплоiзолювальних плит iз деревної шерстi знижується до 0,079 Вт/(м•K) вiдповiдно. Особливостi гальмування процесу передавання тепла до матерiалу, що виготовлений з деревної шерстi i клеєного в'яжучого, пов'язано з утворенням пор. Це пояснюється тим, що в не великих порах вiдсутнiй рух повiтря, що супроводжується перенесенням тепла. Теплопровiднiсть однорiдного матерiалу залежить вiд об'ємної маси. Так, зi зменшенням об'ємної маси матерiалу до 183 кг/м 3 теплопровiднiсть зменшується в 1,67 рази, i навпаки при застосуваннi дошки теплопровiднiсть знижується лише в 1,1 рази. Це дозволяє стверджувати про вiдповiднiсть виявленого реальному механiзму теплоiзолювання i виявлених умов формування властивостей матерiалу на основi деревної шерстi i неорганiчного та органо-мiнерального в'яжучого та практичну привабливiсть запропонованих технологiчних рiшень, а саме застосування низькоякiсної деревини. Останнi, зокрема, стосуються визначення кiлькостi складової в'яжучого. Таким чином, є пiдстави стверджувати про можливiсть спрямованого регулювання процесiв формування деревинних теплоiзоляцiйних матерiалiв шляхом використання деревної шерстi i неорганiчного та органо-мiнерального в'яжучого, якi здатнi утворювати на поверхнi матерiалу вогнезахисну плiвку Ключовi слова: теплоiзоляцiйнi матерiали, деревна шерсть, теплопровiднiсть, теплоємнiсть, неорганiчне i органо-мiнеральне в'яжуче

“…The coating initially has the maximum value of flame-retardant efficiency with the same dynamics of its reduction; accordingly, it would have a lifetime that is much longer due to the reserve of the actual value of the efficiency parameter [1,2]. Given the different character of change in the flame retardant properties due to the conditions and operation duration, the ratio of coatings' service life might prove to be unpredictable, since wood can adsorb moisture from air, which could lead to loss of adhesion by the coating, as well as and its shedding [3,4]. In practice, it should be justified that a flame-retardant coating that provides for a certain…”
