Method for treating at least one three-dimensional green body
The invention relates to a method for treating at least one three-dimensional green body (GB), the at least one three-dimensional green body (GB) comprising an inorganic powder (IP) and a binder (B), the binder (B) comprising at least one polyoxymethylene (POM) as component (b1). In the method, 0.01% to 5.0% by weight, based on the total weight of the at least one three-dimensional green body (GB), of anhydrous oxalic acid is provided, in the presence of an inert gas at lt; at least one three-dimensional green body (GB) is treated with the anhydrous oxalic acid at a temperature (T1) of 140 DEG C. The invention further relates to a three-dimensional palm body (BB) produced by this method and to a three-dimensional sintered body (SB) produced from this three-dimensional palm body (BB). The invention further relates to a device in which the method is carried out.
本发明涉及一种用于处理至少一种三维生坯体(GB)的方法，其中该至少一种三维生坯体(GB)包含无机粉末(IP)和粘合剂(B)，该粘合剂(B)包含至少一种聚甲醛(POM)作为组分(b1)。在该方法中，提供基于至少一种三维生坯体(GB)的总重量按重量计0.01％至5.0％的无水草酸，在惰性气体的存在下在<140℃的温度(T1)下用该无水草酸处理至少一种三维生坯体(GB)。本发明进一步涉及一种通过该方法制备的三维棕坯体(BB)，并且涉及一种由该三维棕坯体(BB)制备的三维烧结体(SB)。此外，本发明涉及一种装置，在该装置中进行该方法。
