Abstract
Метод за получаване на плоскости от дървесини частици чрез поликондензацията на аминосоли, които свързват водопроницаеми целулозни частици в присъствие на известен катализатор, характеризиращ се с това, че към смесите се прибавя като катализатор на поликондензацията и концентриран воден разтвор от смес на органичните компоненти формалдехид и карбамид или несмолоподобен продукт от кондензацията на формалдехид и карбамид и неорганичен компонент натриев или калиев хлорид, като органичните и неорганичните компоненти са в съотношение от 0,2 до 1,3 тегл.ч. органични компоненти към 1,0 тегл. Ч. Неорганичен компонент и катализаторът се прибавя към аминокмолата в количество от 1 до 30% тегл. Отнесени към количеството твърда смола, заедно с обичайните количества амониев хлорид. Патентните претенции са формулирани в 3 точкиA method for producing wood particle boards by the polycondensation of amino salts that bind water-permeable cellulose particles in the presence of a known catalyst, characterized in that a concentrated aqueous solution of a mixture of the organic components formaldehyde and urea is added to the mixtures as a polycondensation catalyst or a non-resin-like product of the condensation of formaldehyde and urea and an inorganic component of sodium or potassium chloride, the organic and inorganic components being in a ratio of 0.2 to 1.3 wt. organic components to 1.0 wt. C. The inorganic component and the catalyst are added to the aminocomolate in an amount of 1 to 30% by weight. Referred to the amount of solid resin, together with the usual amounts of ammonium chloride. The patent claims are formulated in 3 points
