Description
(54) РАЗДЕЛИТЕЛЬНОЕ ПОКРЫТИЕ ДЛЯ МОДЕЛЬНОЙ ОСНАСТКИ(54) DIVIDING COATING FOR MODELING EQUIPMENT
В качестве растворител в составе покрыти может использоватьс отработанное дизельное топливо ГОСТ 305-73.As a solvent in the coating composition, spent diesel fuel GOST 305-73 can be used.
Составы и свойства покрыти по изобретению приведены в табл. 1 и 2.The compositions and properties of the coating according to the invention are given in table. 1 and 2.

Смесь отработанного дизельного масла ГОСТ 21046-75 и отработанного дизельного топлива ГОСТ 305-73 обладает способностью образовывать на поверхности ос настки равномерную прочную пленку, котора позвол ет добитьс необходимого количества- съемов при обеспечении хорошего качества поверхности форм, и стержней.A mixture of spent diesel oil compliant with GOST 21046-75 and spent diesel fuel GOST 305-73 has the ability to form a uniform, durable film on the surface of the core that allows you to achieve the required amount of pickups while ensuring good surface quality of the molds and rods.
При уменьшении в составе покрыти отработанного дизельного масла, менее 20 вес. ч., уменьшаетс в зкость покрыти и на поверхности моделей получаетс тонкий слой, что приводит к прилипанию смеси к оснастке и ухудшению качества поверхности форм, возможны подрывы. При увеличении в составе покрыти отработанного дизельного масла, более 50 вес. ч., в зкость покрыти увеличиваетс , что приводит также к ухудшению качества поверхности форм.With a decrease in the composition of the coating of spent diesel oil, less than 20 wt. hours, the viscosity of the coating is reduced and a thin layer is obtained on the surface of the models, which leads to adhesion of the mixture to the rigging and deterioration of the quality of the surface of the molds, and possible explosions. With an increase in the composition of the coating of spent diesel oil, more than 50 weight. hours, the viscosity of the coating increases, which also leads to a deterioration in the surface quality of the molds.
Покрытие по изобретению не требует специального приготовлени и дешево, так как вл етс отходом. Наноситс покрытие на модельную оснастку любым из известных способов.The coating of the invention does not require special preparation and is cheap as it is a waste. The coating is applied to the tooling by any of the known methods.
Использование предлагаемого изобретени позвол ет устранить прилипаемость холодно-твердеюших смесей к металлической модельной оснастке и увеличить срок ,службы оснастки на 30%.The use of the invention allows to eliminate the adhesion of cold-hardening mixtures to metal model equipment and to increase the service life of the equipment by 30%.
