摘要： The invention relates to a method for manufacturing a glass tube with a coated inner surface by drawing a glass melt (5) to a bag (8) of softened glass and hot forming to a glass tube (9). During the process a substance is introduced into the bag (8) of softened glass. According to the invention the substance is introduced as an aerosol and the inner surface is coated by means of the substance during the hot forming. The method permits economical internal coating with a continuous glass drawing method. The use of aggressive chemical substances for internal coating can be dispensed with according to the invention. As a result, for example, internally coated glass tubes with improved hydrolytic resistance can be manufactured. The invention also relates to a suitable apparatus for manufacturing internally coated glass tubes and the use of glass tubes manufactured by this means for further processing to a hollow, internally coated formed glass body, for example, as primary packaging in the pharmaceuticals field.
摘要翻译：本发明涉及一种通过将玻璃熔体（5）拉伸到软化玻璃袋（8）并热成型为玻璃管（9）而制造具有涂覆内表面的玻璃管的方法。在该过程中，将物质引入软化玻璃的袋（8）中。根据本发明，物质作为气溶胶引入，并且在热成型期间通过物质涂覆内表面。该方法允许经由连续的玻璃拉伸法进行经济的内部涂覆。根据本发明可以省去使用侵蚀性化学物质进行内部涂覆。结果，例如，可以制造具有改善的耐水解性的内部涂覆的玻璃管。本发明还涉及用于制造内部涂覆的玻璃管的合适装置以及使用这种装置制造的玻璃管，用于进一步加工成中空的内部涂覆的成形玻璃体，例如作为药物领域中的初级包装。
