Description
Обычно при изготовлении точного лить примен ютс разовые модели , которые в насто щее врем изготовл ютс из различных органических материалов. Используемые материалы дороги, а по физико-механичаоким и технологическим свойствам полностью не отвечают предъ вл емым требовани м.Typically, in the manufacture of precision casting, one-off models are used, which are currently manufactured from various organic materials. The materials used are expensive, and they do not fully meet the requirements for physicomechanical and technological properties.
Предлагаемый модельный состав не имеет указанных недостатков. Он примен етс в виде пасты, в состав которой входит 75-90% растворимых в воде солей (хлористых, азотистых и др.) и 10-25% легкоплавких органических материалов типа парафина, стеарина и других. Такой модельный состав дешевле, кроме того устран етс гигроскопичность и повышаютс его механические свойства.The proposed model composition does not have these disadvantages. It is used in the form of a paste, which contains 75-90% of water-soluble salts (chloride, nitrogenous, etc.) and 10-25% of low-melting organic materials such as paraffin, stearin, and others. Such a model composition is cheaper, moreover, hygroscopicity is eliminated and its mechanical properties are improved.
Перед приготовлением пасты указанные соли высушиваютс при температурах, примерно, 200-400°. Высушенна соль подвергаетс размалыванию и просеиванию. Суха 1;ол на пудра нагреваетс до 90- 120° и при тщательном ее перемешивании производитс добавка указанных органических материалов. Количество добавл емых органических материалов зависит от желаемой густоты пасты.Before cooking the paste, these salts are dried at temperatures of about 200-400 ° C. The dried salt is milled and screened. Dry 1; ol powder is heated to 90-120 ° and with thorough mixing it adds these organic materials. The amount of organic material added depends on the desired thickness of the paste.
Заполнение металлических форм можно производить прессованием или свободной заливкой. После отвердевани пасты модель удал етс обычным способом.Filling of metal molds can be done by pressing or free pouring. After the paste has hardened, the model is removed in the usual way.
Удаление моделей из форм осуществл етс в гор чей воде. При этом органическа часть модели расплавл етс и всплывает на поверхность вод ной ванны, а сол на часть модели раствор етс .The removal of models from molds is carried out in hot water. In this case, the organic part of the model melts and floats on the surface of the water bath, and the salt dissolves to a part of the model.

Модельный состав дл изготовлени выплавл емых моделей, отличающийс тем, что, с целью его удешевлени , устранени гигроскопичности и повышени механических свойств, он применен в виде пасты, в состав которой входит 75-90% растворимых в воде солей (хлористых, азотистых и др.) и 10-25% легкоплавких органических материалов типа парафина, стеарина и других.A model composition for the manufacture of melted models, characterized in that, in order to reduce its cost, eliminate hygroscopicity and improve mechanical properties, it is applied in the form of a paste, which contains 75-90% of water-soluble salts (chloride, nitrogenous, etc. ) and 10-25% of low-melting organic materials such as paraffin, stearin and others.
