Description
Изобретение относитс к составам дл удалени полимерных покрытий, в частности покрытий на основе эпоксидных и полиуретановых клеев и компаундов.The invention relates to compositions for removing polymeric coatings, in particular coatings based on epoxy and polyurethane adhesives and compounds.
Цель изобретени - повышение эффективности удалени покрытий на основе эпоксидных и полиуретановых клеев и компаундов .The purpose of the invention is to increase the removal efficiency of coatings based on epoxy and polyurethane adhesives and compounds.
В таблице представлены примеры, иллюстрирующие изобретение.The table shows examples illustrating the invention.
Смесь диметилформамида, ксилола, диоксана представл ет собой азеотропную смесь, кип щую npnt 102°C. Реакци растворени полиуретановых компаундов идет при нагревании до 80-85°С. Реакци деполимеризации клеевой пленки начинаетс после 20-30-минутного воздействи температуры .A mixture of dimethylformamide, xylene, dioxane is an azeotropic mixture boiling with npnt 102 ° C. The dissolution reaction of polyurethane compounds takes place when heated to 80-85 ° C. The depolymerization of the adhesive film starts after a 20-30 minute exposure to temperature.
Работа по расклейке узлов и деталей проводитс в химическом боксе с выт жкой, скорость выт жки 1 м/с. Операционный работник пр мого контакта со смесью не имеет. Открытого испарени смеси не допускаетс .The work of putting up knots and parts is carried out in a chemical box with a draw; the speed of drawing is 1 m / s. The operating officer has no direct contact with the mixture. Open evaporation of the mixture is not allowed.
По истечении ориентировочною времени расклейки 6-8 ч (до полного растворени полиуретанового компаунда или эпоксидного ) смесь сливаетс в сборник отходов ПВЖ дл утилизации Расклеенные детали промывают изопропиловым спиртом который также сливаетс в сборник отходов ЛВЖAfter an estimated decoupling time of 6-8 hours (until the polyurethane compound or epoxy compound is completely dissolved), the mixture is discharged into the waste collection container for recycling. The glued parts are washed with isopropyl alcohol, which is also discharged into the waste collection mixture
