Abstract
1. СПОСОБ ОБРАБОТКИ ДРЕВЕСНЫХ МАТЕРИАЛОВ, включающий накалывание древесных материалов и раздельную пропитку водорастворимыми силикатами и защитными сол ми металлов, отличающийс тем, что, с целью повыщени качества обработки, пропитку древесных материалов защитными сол ми осуществл ют перед обработкой водорастворимыми силикатами , причем перед обработкой силикатами материалы пропитывают раствором едкого натра. 2. Способ, по п. 1, отличающийс тем, что раствор едкого натра .используют концентрацией 1,5-3,0%.1. METHOD OF PROCESSING WOOD MATERIAL comprising impaling timber and separate impregnations of water-soluble silicates and the protective metal salts, characterized in that, with a view to the Enhance quality processing, impregnating woody materials protective salts is carried out before the treatment with water-soluble silicates, the silicates before treatment materials are impregnated with caustic soda solution. 2. A method according to claim 1, characterized in that the caustic soda solution is used in a concentration of 1.5-3.0%.

Изобретение относитс к деревообрабатывающей промышленности, в частности к способам защитной обработки древесины и древесных материалов.The invention relates to the woodworking industry, in particular to methods for the protective treatment of wood and wood materials.
Известен способ защитной обработки древесины , состо щий из пропитки силиката-ми и сол ми металлов 1.There is a known method for the protective treatment of wood, which consists of the impregnation of silicates and metal salts 1.
Известен также способ обработки древесных материалов, включающий раздельную пропитку древесных материалов водорастворимыми силикатами и защитными сол ми металлов 2.A method of treating wood materials is also known, including the separate impregnation of wood materials with water soluble silicates and protective salts of metals 2.
Недостатком этих способов вл етс низкое качество обработки.The disadvantage of these methods is low quality processing.
Цель изобретени - повыщение качества обработки.The purpose of the invention is to increase the quality of processing.
Указанна цель достигаетс тем, что пропитку древесных материалов защитными сол ми осуществл ют перед обработкой водорастворимыми силикатами, причем перед обработкой силикатами материалы пропитывают раствором едкого натра, весины, состо щий из пропитки силикатаThis goal is achieved by the fact that the impregnation of wood materials with protective salts is carried out before the treatment with water-soluble silicates, and before the treatment with silicates the materials are impregnated with a solution of sodium hydroxide, which consists of the impregnation of silicate
Раствор едкого натра используют концентрацией 1,5-3,0 7, .A solution of caustic soda is used at a concentration of 1.5-3.0 7,.
Пример осуществлени способа.An example of the method.
Провод т защитную обработку сосновых образцов пр моугольного сечени , размеры которых равны 150x150x500 мм, приProtective treatment of pine samples of rectangular cross section, the dimensions of which are equal to 150x150x500 mm, is carried out,
этом дл получени контрольных данных провод т параллельное испытание таких же образцов беззащитной обработки.To obtain control data, a parallel test of the same samples of defenseless processing is carried out.
Согласно известному способу пропитывают образцы в растворе силиката натри 3 чAccording to a known method, the samples are impregnated in a solution of sodium silicate for 3 hours.
затем сущат до 8-10 % влажности и пропитывают 3 ч в растворе хромированного хлорида цинка. Образцы подсущивают 3- 4 сут. Согласно предлагаемому способу вначале образцы пропитывают раствором хромированного хлорида цинка концентрацией 1,5-3,0% , а затем после сушки выполн ют пропитку водным раствором едкого натра концентрацией 1,5-3,0% и пропитку водным раствором силиката натри концентрацией 1,5-3,0%, при этом образцы пропитывают в три цикла. На первом цикле накалывание провод т на гл.убину 75 мм при щаге накалывани 50 мм, на втором цикле - на 50 мм при щаге 25 мм - на третьем цикле - на 25 мм при щаге 12,5 мм, а промежуточную и окончательную сушки провод т до влажности 8-10% .then it is up to 8-10% moisture and impregnated for 3 hours in a solution of chromium-plated zinc chloride. Samples are injected for 3-4 days. According to the proposed method, the samples are first impregnated with a solution of chromed zinc chloride with a concentration of 1.5-3.0%, and then after drying, they are impregnated with an aqueous solution of caustic soda with a concentration of 1.5-3.0% and impregnated with an aqueous solution of sodium silicate with a concentration of 1.5 -3.0%, while the samples are impregnated in three cycles. In the first cycle, the prickling is carried out on the 75 mm thick head with a 50 mm pitting needle, in the second cycle - by 50 mm with a 25 mm pitch - in the third cycle - by 25 mm with a 12.5 mm pitch, and the intermediate and final drying wire t to a moisture content of 8-10%.
Результаты сравнительных испытаний приведены в таблице.The results of the comparative tests are shown in the table.
Предлагаемый способ обработки древесных материалов обеспечивает снижение водопоглощени , разбухани , а также повышение био- и огнестойкости материалов.The proposed method of processing wood materials reduces the water absorption, swelling, as well as increasing the bio-and fire resistance of materials.
