Description
Vynález sa týká prostriedku na odlahčovanie detailných modelov v zubnej technike.BACKGROUND OF THE INVENTION The present invention relates to a device for lightening detailed models in dental technology.
Detailně modely v zubnej technike sa od1'ahčujú lakom na nechty, alebo nitrocelulózovým lakom. Nevýhoda tohoto postupu je, že uvedený lak po nanesení na detailný model tvrdne veími pomaly až niekoíko hodin.Detailed dental models are lightened with nail varnish or nitrocellulose varnish. The disadvantage of this procedure is that said varnish hardens very slowly for several hours after application to the detailed model.
Uvedené nevýhody odstraňuje riešenie podlá vynálezu, ktorý spočívá v tom, že ako odlahčovací prostriedok sa použije roztok acetylcelulózy o koncentrácii 0,5 až 3 g. 1_1 a stupni acetylácie 0,6 až 3 v dichlórmetáne, octane etylnatom, acetone, alebo v zmesi uvedených rozpúšťadiel, obsahujúci 0,05 až 0,2 g . I1 1,2,3,4,5,6-hexa-O-acetyl-D-glukopyranózy, alebo 1,2,3,4,6-penta-O-acetyl-D-glukopyranózy, alebo 2,3,4-tri-O-acetyl-l,6-anhydro-beta-D-glukopyranózy a 0,05 až 0,5 g . . I1 bronzového prášku o velkosti zrna 0,04 až 0,05 mm.The above-mentioned disadvantages are overcome by the solution according to the invention which consists in using a solution of acetylcellulose with a concentration of 0.5 to 3 g. 1 1 and the degree of acetylation of 0.6 to 3 of dichloromethane, ethyl acetate, acetone, or a solvent mixture thereof, containing from 0.05 to 0.2 grams. 1, 1,2,3,4,5,6-hexa-O-acetyl-D-glucopyranose, or 1,2,3,4,6-penta-O-acetyl-D-glucopyranose, or 2,3, 4-tri-O-acetyl-1,6-anhydro-beta-D-glucopyranose and 0.05 to 0.5 g. . I 1 bronze powder with a grain size of 0.04 to 0.05 mm.
Výhodou uvedeného odlahčovacieho prostriedku je, že nanesená vrstva velmi rýchlo, už v priebehu niekolkých minút, tvrdne, pričom vytvořený film acetylcelulózy je dostatečné tvrdý a pri modelácii sa nepoškodzuje. Vytvořený film acetylcelulózy s použitím horeuvedených acetylovaných derivátov glukózy, ako zmakčovadiel, je dostatočne pružný a nelúpe sa ani po dlhšej expozícii na vzduchu. Přednosti nového výrobku a jeho přípravy sú zřejmé z príkladov, ktoré sú vyčerpávajúce ale ilustrativně.The advantage of said deblocking agent is that the deposited layer hardens very quickly, in just a few minutes, the acetyl cellulose film formed being sufficiently hard and not damaged during modeling. The acetylcellulose film formed using the above-mentioned acetylated glucose derivatives as a plasticizer is sufficiently flexible and does not peel even after prolonged exposure to air. The advantages of the new product and its preparation are evident from the examples, which are exhaustive but illustrative.
Příklad 1Example 1
Acetylcelulóza — 0,5 g — o stupni substitúcie acetylovými skupinami 3 sa rozpustí za stálého miešania v dichlórmetáne — 100 milililtrov — pri teplote 20 °C a přidá sa 0,05 grantov 1,2,3,4,6-penta-O-acetyl-D-glukopyranózy a 0,5 g měděného prášku o velkosti zrna 0,0.5 mm. Uvedenu zmes dobré premiešame pretrepaním a natierame štetcom na povrch modelu. Rozpúšťadlo, dichlórmetán sa odpaří v priebehu 30 sekund, pričom vzniká pevný film odlahčovacieho' prostriedku o hrúbke 0,2 mm.Acetylcellulose - 0.5 g - with a degree of substitution by acetyl groups 3 is dissolved with stirring in dichloromethane - 100 milliliter - at 20 ° C and 0.05 grants of 1,2,3,4,6-penta-O- acetyl-D-glucopyranose and 0.5 g copper powder with a grain size of 0.05 mm. Mix the mixture well by shaking and brush it on the surface of the model. The solvent, dichloromethane was evaporated for 30 seconds to give a solid film of the deblocking agent 0.2 mm thick.

Rozpúšťadlo sa odpaří v priebehu 1 minuty, pričom vzniká pevný film odlahčovacieho prostriedku o hrúbke 0,17 mm.The solution according to Example 1, except that acetylcellulose with a degree of substitution of 0.6 is used at a concentration of 3 gl 1 and is dissolved in a mixture of 60 ml of dichloromethane and 40 ml of ethyl acetate and mixed thoroughly to add 0.2 g of 2.3. 4-tri-O-acetyl-l, 6-anhydro-.beta.-D-glucopyranose and 0.5 gl 1 copper powder of grain size of 0.01 mm. The solvent was evaporated in 1 minute to give a solid film of the deblocking agent 0.17 mm thick.
