Abstract
Description
производными лантаноида. В аппарат помещают древесину, ввод т водный раствор препарата и создают давление при помощи азота. В конце обработки образцы извлекают и высушивают на воздухе.derivatives of lanthanide. Wood is placed in the apparatus, an aqueous solution of the preparation is introduced and pressurized with nitrogen. At the end of processing, the samples are removed and dried in air.
Дл определени св занного с древесиной лантаноида обработанную древесину промывают проточной водой в течение 12ч, затем высушивают и определ ют количество золы после сжигани образца и прокаливани остатка при 1000°С. Процент золы перед обработкой вычитаетс из процента золы обработанного дерева и, таким образом определ етс количество лантаноида, посто нно св занного с деревом.To determine the wood-bound lanthanide, the treated wood is washed with running water for 12 hours, then dried, and the amount of ash after burning the sample and calcining the residue at 1000 ° C is determined. The percentage of ash before treatment is subtracted from the percentage of ash of the treated wood, and thus the amount of lanthanide permanently bound to the tree is determined.
Исследование разрушени древесины, обработанной производными лантаноидов, показывает, что эффект заметный уже тогда, когда количество золы, обусловленной лантаноидами , составл ет 0,25%A study of the destruction of wood treated with lanthanide derivatives shows that the effect is noticeable even when the amount of ash caused by lanthanides is 0.25%
Исследование показывает также, что образец аффективно защищен от разложени и разрушени под действием микроорганизмов , грибов и насекомых.The study also shows that the sample is affectively protected from decomposition and destruction by the action of microorganisms, fungi and insects.
Результаты испытаний приведены в табл. 1. Все обработки, если нет иных указаний , проводились при комнатной температуре . В опытах 1 - 18 исходна сосна давала 0,08% золы, в других опытах - 0,12 % золы.The test results are shown in Table. 1. All treatments, unless otherwise indicated, were performed at room temperature. In experiments 1–18, the initial pine gave 0.08% ash, in other experiments 0.12% ash.
Результаты испытаний показывают, что чем выше давление, тем больше производных лантаноида образуют посто нные св зи по сравнению с обработкой при атмосферном давлении. Кроме того, при выдержке после обработки процент золы увеличиваетс , что указывает, на продолжение процесса образовани сеток.The test results show that the higher the pressure, the more the lanthanide derivatives form a permanent bond compared to the treatment at atmospheric pressure. In addition, upon exposure after treatment, the percentage of ash increases, indicating that the process of forming the grids continues.
Результаты испытаний приведены в табл.2.The test results are shown in table 2.
П р и м е р 2. Обрабатывают южную желтую сосну производными лантаноидов путам погружени , распылени или нанесени кистью составов, содержащих водный раствор производного лантаноида. Обработанное дерево высушивают и подвергают старению в течение нескольких суток. Дл определени содержани св занных лантаоидов образцы промывают в проточной вое , как описано в примере 1, затем образцы жигают. Результаты испытаний приведены табл.1.EXAMPLE 2. Southern yellow pine is processed with lanthanide derivatives to immersing, spraying or brushing compositions containing an aqueous solution of the lanthanide derivative. Treated wood is dried and aged for several days. To determine the content of the bound lantaoids, the samples are washed in a flow-through manner as described in Example 1, then the samples are burned. The test results are shown in table.1.
Примерз. Стандартные образцы, неFroze Standard samples, not
подвергавшиес предварительной обработке , помещают в двухгорловой реактор, в коором имеетс капельна воронка, в нем находитс 2%-ный водный раствор нитратаsubjected to pretreatment, placed in a two-necked reactor, in which there is a dropping funnel, it contains a 2% aqueous solution of nitrate
цери . В реакторе создают пониженное авление (около 2 мм рт.ст.), которое подерживают в течение 10ч. Реактор заполн ют раствором нитрата цери , и образцы остаютс погруженными в раствор в течение 4 ч. После удалени воды и просушивани на воздухе в течение 10 ч образец промывают в течение 12 ч и затем сжигают. Количество золы в необработанном образце составл ло 0,07% в обработанном образцеceri. In the reactor, create a reduced avavil (about 2 mm Hg), which is maintained for 10 hours. The reactor is filled with a solution of cerium nitrate, and the samples remain immersed in the solution for 4 hours. After removing water and drying in air for 10 hours, the sample is washed for 12 hours and then burned. The amount of ash in the untreated sample was 0.07% in the treated sample.
после промывани - 1,33%.after washing, 1.33%.
