Description

Изобретение относитс к медицине, а именно к стоматологии.The invention relates to medicine, namely to dentistry.
Известен состав дл изготовлени учебных моделей зубных р дов, содержащий кварцевый песок 1.A known composition for the manufacture of educational models of dental series, containing quartz sand 1.
Однако известный состав не обладает высокой твердостью.However, the known composition does not have high hardness.
Цель изобретени - повышение твердости состава.The purpose of the invention is to increase the hardness of the composition.
Цель достигаетс тем, что состав дл изготовлени учебных моделей зубных, р дов , содержащий кварцевый песок, дополнительно содержит карбамид при следующем соотношении компонентов, мае. /о:The goal is achieved by the fact that the composition for the manufacture of training models of dental, rows, containing quartz sand, additionally contains urea in the following ratio of components, May. /about:
Карбамид45-50Urea 45-50
Кварцевый песок50-55Quartz sand 50-55
Дл изготовлени моделей используетс карбамид (техническа мочевина) в смеси с кварцевым песком в соотношении 1:1 - 1:1,2 по весу. Модели получают путем их отливки в формы из эластической пластмассы.For the manufacture of models, urea (technical urea) is used in a mixture with quartz sand in a ratio of 1: 1 to 1: 1.2 by weight. Models are produced by casting them into elastic plastic molds.
Отливку производ т следующим образом .The casting is performed as follows.
В емкость засыпают карбамид, добавл ют соответствующее количество кварцевого песка, после чего нагревают до плавлени и заливают в форму. После отвердевани карбамида модель по своей твердостиCarbamide is poured into the tank, the appropriate amount of quartz sand is added, and then heated to melt and poured into the mold. After hardening the carbamide model in its hardness
схожа с твердыми ткан ми естественных зубов. Твердость модели можено регулировать путем изменени соотнощений карбамида и кварцевого песка. Эластическую форму можно использовать многократно.similar to hard, natural teeth. The hardness of the model can be adjusted by changing the ratios of urea and quartz sand. Elastic form can be used repeatedly.
Пример 1. Берут металлическую посуду емкостью 0,5-1,0 л. В нее засыпают 0,2 кг карбамида и 0,2 кг кварцевого песка. Посуду став т на плиту дл распавлени карбамида (температура плавлени 136°С). Затем подбирают нужную дл отливки стандартную форму модели из эластической пластмассы и заливают в нее расплавленную смесь. При остывании смесь затвердевает , и модель извлекают из формы.Example 1. Take metal dishes with a capacity of 0.5-1.0 liters. 0.2 kg of urea and 0.2 kg of quartz sand are poured into it. The dishes are placed on the stove to dissolve the urea (melting point 136 ° C). Then, the standard shape of the model made from elastic plastic is selected for casting and molten mixture is poured into it. When cooled, the mixture hardens and the model is removed from the mold.
Пример 2. Способ приготовлени аналогичен примеру 1, соотношение карбамида и песка берут 1:1,2.Example 2. The method of preparation is similar to Example 1, the ratio of urea and sand is taken to be 1: 1.2.
Предлагаемый состав дл изготовлени учебных моделей зубных р дов обеспечивает возможность формировани в зубах 0 полостей с четкими границами, получение моделей различной твердости, а также возможность многократной переплавки использованных моделей (безотходна технологи ).The proposed composition for the manufacture of educational models of dental series allows the formation of 0 cavities in the teeth with clear boundaries, obtaining models of different hardness, as well as the possibility of repeated melting of the used models (waste-free technology).
При изготовлении учебных моделей из известных материалов в среднем за 8 ч можно изготовить 10 моделей, а из смеси карбамида с кварцевым песком-50 моделей.In the manufacture of training models from known materials, on average, 8 hours, you can make 10 models, and from a mixture of urea with quartz sand, 50 models.
