Abstract
Изобретение относитс к составам дл обработки торцов древесины и может быть использовано в деревообрабатывающей промышленности и строительстве. Цель изобретени - снижение растрескивани торцов и повышение адгезии к влажной древесине. В состав на основе жидкого стекла и минеральных наполнителей дополнительно вводитс аммоний тиосурьм нокислый и полиэтиленполиамин, при этом адгези к влажной древесине повышаетс в 1,3-1,5 раза, растрескивание торцов снижаетс на 20%, а влагоемкость повышаетс в 2 раза. 1 табл.The invention relates to compositions for processing the ends of wood and can be used in the woodworking industry and construction. The purpose of the invention is to reduce the cracking of the ends and to increase the adhesion to damp wood. The composition based on liquid glass and mineral fillers is additionally added with ammonium thio-sour and polyethylene polyamine, while the adhesion to damp wood increases 1.3-1.5 times, the cracking of the ends decreases by 20%, and the water-holding capacity increases 2 times. 1 tab.
Description
Изобретение относитс к составам дл обработки торцов древесины и может быть использовано в деревообрабатывающей промышленности и строительстве .The invention relates to compositions for processing the ends of wood and can be used in the woodworking industry and construction.
Цель изобретени - снижение растрескивани торцов и повышение адгезии к влажной древесине.The purpose of the invention is to reduce the cracking of the ends and to increase the adhesion to damp wood.
Введение полиэтиленполиамина пре- дотвр ащает коагул цию силиката натри при введении минерального наполнител . Увеличение содержани полиэтилен- полиамина более 0,8 мас.% ведет к снижению адгезии покрыти к влажной древесине, при содержании менее 0,05 мас.% уменьшаетс эффект стабилизации .The introduction of polyethylene polyamine predotravatsya coagulation of sodium silicate with the introduction of mineral filler. An increase in the polyethylene-polyamine content of more than 0.8 wt.% Leads to a decrease in the adhesion of the coating to moist wood, with a content of less than 0.05 wt.%, The stabilization effect decreases.
Снижение растрескивани торцов древесины и повышение атмосферостой- кости достигаетс введением аммони тиосурьм нокислого в сочетании с мелом и лигнином.A reduction in the cracking of the wood ends and an increase in weather resistance is achieved by the introduction of ammonium hydroxide in combination with chalk and lignin.
Приготовление состава. Силикат натри раствор ют в воде. Затем ввод т полиэтиленполиамин и тщательно перемешивают смесь. Затем ввод т мел, лигнин, минеральный наполнитель и аммоний тиосурьм нокислый. Добавкой воды довод т состав до необходимой консистенции. Состав на торцы древесины можно наносить кистью или с помощью распылител . Составы и основные показатели приведены в таблице.Preparation of the composition. Sodium silicate is dissolved in water. Then polyethylene polyamine is introduced and the mixture is thoroughly mixed. Chalk, lignin, mineral filler and ammonium hydrogen sulphate are then added. Add water to the required consistency. The composition on the ends of wood can be applied with a brush or using a spray gun. The compositions and main indicators are given in the table.
Защитные свойства покрыти оцениваютс по количеству деталей, отошедших в брак после сушки покрыти .The protective properties of the coating are evaluated by the number of parts left in the marriage after drying the coating.
Предложенный состав снижает растрескивание торцов на 20%, повышает адгезию покрыти к влажной древесине в 1,3-1,5 раза. Увеличивает влагостойкость в 2 раза. Экономический эффект от использовани предлагаемого состава составит 70,0 тыс.рубв год.The proposed composition reduces the end cracking by 20%, increases the adhesion of the coating to damp wood by 1.3-1.5 times. Increases moisture resistance by 2 times. The economic effect from the use of the proposed composition will be 70.0 thousand rubles a year.
