Description
Изобретение относитс к способам ХОЛОДНОГО фосфатировани изделий из черных металлов с целью защиты их от коррозии. Известные способы такого рода, предусматривающие обработку изделий растворами фосфатов т желых металлов с концентрацией раствора до 100 , не обеспечивают достаточно высоких антикоррозионных свойств покрыти и требуют об зательной последующей промывки издели водой.The invention relates to methods for COLD Phosphating of ferrous products in order to protect them from corrosion. Known methods of this kind, involving the treatment of products with phosphate solutions of heavy metals with a solution concentration of up to 100, do not provide sufficiently high anticorrosive properties of the coating and require the subsequent subsequent washing of the product with water.
Дл улучшени защитных свойств покрыти и устранени необходимости промывки изделий после фосфатировани предлагаетс , согласно изобретению, использовать дл фосфатировани растворы фосфатов т желых металлов с концентрацией от 100 до 300 /л.In order to improve the protective properties of the coating and eliminate the need for washing products after phosphating, it is proposed, according to the invention, to use phosphate solutions of heavy metal phosphates with concentrations ranging from 100 to 300 / l.
При этом на изделии образуютс запд,итные пленки высокой прочности с хорошими антикоррозионными свойствами, и не требуетс промывка издели водой после фосфатпровани . Растворы могут наноситьс на обрабатываемую поверхность любым из известных способов, например, пульверизатором, кистью, тампоно.мIn this case, zapt, high-strength films with good anti-corrosion properties are formed on the product, and the product is not required to be washed with water after phosphate. Solutions can be applied to the surface to be treated using any of the known methods, for example, a spray gun, brush, tampon.m
и т. п. Возмол но погружение издели в раствор на 10-12 мин. Растворы ДЛЯ фосфатировани могут примеи тьс как в холодном, так и в нагретом до 50-80° состо нии. После нанесени фосфатирующего раствора производитс сушка изделий на воздухе или в сушильной камере . После сушки может производитьс грунтовка ИЛИ окраска изделий . Устранение необ.кодимости промывки изделий водой упрощает процесс фосфатировани и делает его пригодным ДЛЯ обработки крупногабаритных изделий, мостов, арок и других сооружений, которые в дальнейшем подвергаютс окраске.etc. It is possible to immerse the product in the solution for 10-12 minutes. Phosphating solutions can be used in both cold and heated to 50-80 ° C states. After applying the phosphating solution, the products are dried in air or in a drying chamber. After drying, a primer can be made OR the painting of the products. The elimination of the need for water washing of the products simplifies the process of phosphating and makes it suitable for processing large-sized products, bridges, arches and other structures, which are subsequently subjected to painting.
Предмет изобретени Subject invention
Способ ХОЛОДНОГО фосфатировани изделий из черных металлов, о тл н чаю т. и и с тем, что, с целью за1циты изделий от коррозии и исключени последующей операции промывки фосфатной пленки, примен ют растворы фосфатов т желых металлов концентрацией от 100 до 300 г1л.The method of COLD Phosphating of products from ferrous metals, for example, and so that, in order to protect products from corrosion and eliminate the subsequent operation of washing a phosphate film, heavy phosphate solutions with concentrations ranging from 100 to 300 grams are used.
