Description
Изобретение относитс к составу дл повышени электропроводности древесины перед отделкой электростатическим способом распылени , предназначенному дл использовани в мебельной, деревообрабатывающей и других отрасл х промышленности.The invention relates to a composition for increasing the electrical conductivity of wood before finishing with an electrostatic spray method, intended for use in the furniture, woodworking and other industries.
Известен состав дл повышени электропроводности , например грунтовка на основе поливинилацетатной эмульсии, в который ввод т ортофосфорную кислоту в количестве 5-6%. Недостатком известного способа вл етс то, что кислота, действу на древесину, измен ет ее цвет, ухудшает качество изделий, изготавливаемых под естественный цвет. При обработке известным составом окрашенных изделий кислота, взаимодейству с красител ми , измен ет тон окраски.A known composition for increasing electrical conductivity, for example, a primer based on polyvinyl acetate emulsion, in which orthophosphoric acid is introduced in an amount of 5-6%. The disadvantage of this method is that the acid, acting on wood, changes its color, impairs the quality of products manufactured under natural color. When processing a known composition of colored products, the acid, which interacts with dyes, changes the color tone.
С целью повышени качества отделки издели электролакированием в предлагаемый состав введен хлористый натрий (NaCl). Компоненты состава вз ты в следующем соотношении (в %):In order to improve the quality of the finish of the product by electroplating, sodium chloride (NaCl) was added to the proposed composition. The components of the formulation are taken in the following ratio (in%):
Поливинилацетатна эмульси Polyvinyl acetate emulsion
«СВ 99-101"CB 99-101
Уайт-спирит17-19White spirit17-19
Олифа «Оксоль 19-21Drying oil "Oksol 19-21
Предлагаемый способ повышает электропроводность древесины без изменени цвета и текстуры и долгое врем сохран ет стабильность поверхностей электропроводности нослеThe proposed method increases the electrical conductivity of the wood without changing the color and texture and for a long time maintains the stability of the electrical conductivity surfaces.
покрыти .cover
Хлористый натрий ввод т в грунтовочные или крас щие составы в виде водного раствора .Sodium chloride is introduced into the primer or coloring compositions in the form of an aqueous solution.
После нанесени на поверхность изделий изAfter applying to the surface products from
древесины предложенного состава производитс выдержка 25-30 мин при 20-22°С, а затем лакировка на электростатической установке . Удельное поверхностное сопротивление перед лакированием составл ет 10 ом. Стабильность поверхностной электропроводности предлагаемого состава объ сн етс гигроскопичностью хлористого натри , способного удерживать влагу или адсорбировать ее из воздуха, насыщенного вод ным наром в камере перед электрорасныл ющей кабиной.Wood of the proposed composition is aged for 25-30 minutes at 20-22 ° C, and then varnished in an electrostatic unit. The surface resistivity before varnishing is 10 ohms. The stability of the surface conductivity of the proposed composition is explained by the hygroscopicity of sodium chloride, which is able to retain moisture or adsorb it from air saturated with water nara in the chamber in front of the electric booth.
