Description
Изобретение относитс к лакокрасочной промышленности, в частности к составам дл удалени старых лакокрасочных покрытий без применени механических средств очистки.The invention relates to the paint industry, in particular to compositions for removing old paint coatings without the use of mechanical cleaning agents.
Срок службы лакокрасочных покрытий в среднем составл ет -3 года, срок службы изделий в основном значительно больше. Поэтому возникает необходимость их перекраски . Удаление старых лакокрасочных покрытий механическими методами очень трудоемкий процесс.The service life of paint coatings is on average -3 years, the service life of products is basically much longer. Therefore, it is necessary to repaint them. Removal of old paintwork by mechanical methods is a very laborious process.
Известные составы дл сн ти старых лакокрасочных покрытий дел тс на две большие группы: кислотно-щелочные и на основе органических растворителей.The known compositions for removing old paint coatings are divided into two large groups: acid-base and based on organic solvents.
При примене)1ии смывок на основе кислот и щелочей требуетс специальна аппаратура, подогрев, они вызывают коррозию как аппаратуры , так и металлической нодложкн, с которой удал етс покрытие. Таким способом можно удал ть покрыти с деталей небольших размеров. Вредные испарени кислот и щелочей создают т желые рабочие услови .When using acid and alkali based washes, special equipment is required; heating is necessary; they cause corrosion of both the equipment and the metal floor that the coating is removed from. In this way, coatings can be removed from small parts. Harmful evaporation of acids and alkalis create difficult working conditions.
Смывки на основе органических растворителей используютс более широко, но в их состав, хот и в небольших количествах, также вход т органические кислоты или щелочи, вызывающие коррозионное разрушение металлической подложки.Organic solvent based washes are used more widely, but their composition, although in small quantities, also includes organic acids or alkalis, which cause corrosion of the metal substrate.
