Description
Дл улучшени податливости и выбиваемости формовочных смесей на основе жидкого стекла известно введение комбинированной добавки, содержащей, кроме силиката натри , органические соединени , состо щие из нескольких гидроксильных грунп, например глюкозы, патоки, глицерина и т. д.To improve the flexibility and knock-out of liquid glass-based molding sands, the introduction of a combination additive containing, in addition to sodium silicate, organic compounds consisting of several hydroxyl primers, such as glucose, syrup, glycerin, etc., is known.
Особенность описываемого св зующего заключаетс в том, что в жидкое стекло ввод т до 35% двойного соединени Сахаров с хлористым натрием, предварительно обработанного едким натром до рН 7-9. Это облегчает выбивку смеси из отливок.The specific feature of the described binder is that up to 35% of the double compound of sugars with sodium chloride, previously treated with caustic soda to a pH of 7-9, is introduced into the liquid glass. This makes it easier to knock out a mixture of castings.
Жидкое стекло предварительно подогревают дл повышени стабильности свойств св зующего при продолжительном хранении его.Liquid glass is pre-heated to increase the stability of the properties of the binder with long-term storage.
