Description
Technical field
The present invention relates to a kind of Gutta extraction device, specifically refer to spiral, annular two-stage series gutta-percha leaching device.
Background technology
Gutta-percha is present in folium cortex eucommiae, skin and fruit.Gutta-percha is identical with chemistry of natural rubber composition, but molecular structure is different, and gutta-percha is using trans-polyisoprene, and natural rubber is cis-polyisoprene.Due to gutta-percha molecule of the same race because vulcanization is different, not only can present rubbery state but also can present different plastics states, thus gutta-percha has very important using value, is a kind of emerging and functional material served many purposes.
Gutta-percha is soluble in the non-polar solvens such as benzinum, after adopting the non-polar solvens such as benzinum to extract, lower the temperature again to freeze to analyse gutta-percha crystal to be separated out and be separated, but the extraction of gutta-percha belongs to new industry, the proterties of bark of eucommia material is also comparatively unique, almost there is no the mature experience that can use for reference and technology, it is feasible for carrying out that hot dipping goes out with the benzinum of 60-90 DEG C of boiling range to gutta-percha, but the solubility of gutta-percha in benzinum is less, and be easy to be formed as nasal mucus shape affects the infiltration of solvent, material is tied as soft board, has been difficult to leaching operation; If take conventional grease leaching system, there is the series difficulty such as high, the difficult infiltration of little, the molten consumption of solid-liquid ratio, difficult precipitation, difficult evaporation, easily blocking, running is leached in the industrialization that realize gutta-percha, must design brand-new gutta-percha leaching device.
