Description
При ТОЧНОМ литье по вы-полн емым модел м примен ютс различные модельные составы. Известны модельные составы, в которые вход т такие составл ющие как парафин, буроугольный воск, канифоль и полиэтилен.In EXACT casting on full models, various model compositions are used. Model compositions are known in which such constituents as paraffin, lignite wax, rosin and polyethylene are included.
В предлагаемый модельный состав вход т эти же вещества, но он отличаетс от известных соотношением компонентов, при котором повыщаетс прочность и теплостойкость состава и уменьщаетс его линейна усадка.The proposed model composition includes the same substances, but it differs from the known ratio of components, which increases the strength and heat resistance of the composition and reduces its linear shrinkage.
В модельный состав вход т (в вес. %): парафин58The model composition includes (in wt.%): Paraffin58

полиэтилен2polyethylene2
Модельный состав приготовл етс в виде однородной массы и запрессовываетс в пресс-формы в пастообразном состо нии при температуре 49-53° любым из существующих способов.The model composition is prepared in the form of a homogeneous mass and is pressed into a mold in a paste-like state at a temperature of 49-53 ° by any of the existing methods.
Наличие в модельном составе полиэтилена в количестве до 2% придает модел м высокую теплостойкость и прочность и обеспечивает требуемое качество керамики формы. Повышенна теплостойкость и проч-. ность модельного состава делают его пригодным дл ,р.аботы как в обычных услови х, так и при повышенных температурах производственного помендени (до 35°).The presence in the model composition of polyethylene in the amount of up to 2% gives the models high heat resistance and strength and provides the required quality of the ceramic form. Increased heat resistance and dura-. The composition of the model composition makes it suitable for working both under normal conditions and at elevated production temperatures (up to 35 °).
Состав имеет следующие свойства: температура разм гчени 48-50°, прочность 34 кг/мм и линейна усадка 1,2%.The composition has the following properties: softening temperature 48-50 °, strength 34 kg / mm and linear shrinkage 1.2%.
Описанный состав может быть использован в качестве заменител парафино-стеариновых .модельных составов при производстве точного лить по выплавл емым модел м и рекомендуетс дл использовани в серийном и мелкосерийном производстве.The described composition can be used as a substitute for paraffin-stearic model compositions in the manufacture of precision casting on melted models and is recommended for use in serial and small-scale production.
