Description
Дл Придании водостойкости издели м из бсЬковых вещестБ их обрабатывают формальдегидом путем погружении в раствор формалииа или -лрибаики в формуемую -массу веществ, выдел ющих при разложении; формальдегид .In order to impart water resistance to articles of bcc substances, they are treated with formaldehyde by immersing them in a solution of formalia or lribaik in a formable mass of substances evolving during decomposition; formaldehyde.
Однако задубка в водных формальдегидных растворах вызывает короблеиие и дает до отходов; задубка путем добЯВКИ формальдегндкых соединений в белковую массу преждевременно Иачинае-т дубить последнюю , вследствие чего дальнейша обработка материала весьма затруднител1 на .However, the process of watering in aqueous formaldehyde solutions causes contort and gives up to waste; by adding the formaldegnd compounds to the protein mass prematurely, tanning them to tan the latter, as a result of which further processing of the material is very difficult.
Добавка п массу замедлителей дублени дл продотвращоии преждевix мeннoгo де11стви формальдегида не дала удовлетворительных результатов .The addition of a mass of tanning inhibitors to prevent premature mining of formaldehyde did not give satisfactory results.
С целью избежани указанных неблагопри тных влений предлагаетс способ, согласно которому устран етс }(еобходимость дублени в растворах или при обработке белковой массьг.In order to avoid the aforementioned adverse events, a method is proposed according to which is eliminated} (the necessity of tanning in solutions or during processing of protein mass.
Способ заключаетс в том, что дуб щее вещество нанос т на поверхность рондельки- или какой-либо другой заготовки; белкового пластика непосредственно перед прессо;ванием или тиснением. Дуб н;ее вещество подсыпают в прессформу или же обсыпают или обмазывают пластик перед закладыванием его в п Х ссформьг, Этеш достигаетс сокращение длительности процесса дублени .The method consists in that the oak substance is applied to the surface of a randelka or some other preform; protein plastic immediately before pressing or embossing. Oak n; its substance is poured into the mold, or sprinkled or coated with plastic before laying it in the form of the mold, Ettesh shortening the tanning process is achieved.
