Description
Известна смесь дл изготовлени литейных стержней, содержаща наполнитель, фенолъную смолу, сульфигнонсииртовую барду, отвердитель , например гидравлическое в жущее .A known mixture for the manufacture of casting cores, containing a filler, a phenolic resin, a sulfonic nitrate bard, a hardener, for example a hydraulic binder.
Цель изобретени - ускорить процесс отверждени при нормальной температуре и повысить проч ность стержней и форм.The purpose of the invention is to accelerate the curing process at normal temperature and increase the strength of the rods and shapes.
Дл этого в состав смеси введены эфиры целлюлозы в количестве 0,2-4,0 вес. %. При этом в качестве эфиров целлюлозы ввод т либо .нитроцеллюлозу, либо ацетилцеллюлозу .For this purpose, cellulose ethers are introduced into the mixture in an amount of 0.2-4.0 weight. % At the same time, either nitrocellulose or cellulose acetate is introduced as cellulose ethers.
Стержни выдерживают в оснастке 3- 5 мин. Дальнейшее отверждеи-ие происхо дит на воздухе. Максимальна прочность достигаетс за 4-6 час. Прочность при раот н ении к этому времени равна 9-12 кг/с.и и сохран етс в течение 24-48 час.The rods are kept in a snap for 3-5 minutes. Further cure occurs in air. Maximum strength is reached in 4-6 hours. The strength when working by this time is 9–12 kg / s. And lasts for 24–48 hours.
