The results show that: the tensile strength, flexural strength and flexural modulus increase by about 10.4%, 62.1% and 122.3% respectively when the mass fraction of the aluminum powder increases from 0 to 50%, while elongation at break and impact strength decrease by about 65.0 and 74.4% respectively; the tensile strength, elongation at break and impact strength all increase with decreasing the particle sizes of the aluminum powders.b Nylon-12 coated metal powders for the indirect SLS process were prepared by the dissolution precipitation process. The coated powders have only 1.0 wt% nylon-12, and their SLS green parts have sufficient strength for features as small as 1.0 mm to be built and post-processed and high dimensional accuracy. The green parts were subjected to the post processing processes including binder decomposition and infiltration of epoxy resin, and then the metal/polymer composite parts with relatively high strength and accuracy were formed.At present, micron-scale inorganic fillers have been widely used to reinforce nylon SLS parts.

将该法制备的尼龙12覆膜金属粉末用于以下两个方面：a使用铝粉增强尼龙12的SLS成形件，通过溶剂沉淀法制备尼龙12覆膜铝复合粉末，研究了铝粉含量及粒径对SLS成形件性能的影响，结果表明：铝粉分散均匀，并与基体有良好的界面粘接；当铝粉含量从0增加到50wt％时，成形件的拉伸强度、弯曲强度、弯曲模量分别提高10.4％、62.1％和122.3％，冲击强度和断裂伸长率下降65.0％和74.4％，耐热性及尺寸精度也得到提高；断裂伸长率、冲击强度及拉伸强度均随着铝粉粒径的减小而增大。b使用溶剂沉淀法制备了间接法SLS用尼龙12覆膜金属粉末，该覆膜粉末中聚合物粘接剂的含量仅为1.0 wt％，其SLS初始形坯具有较高的精度以及足够满足后处理要求的强度，最小精细结构的尺寸达1.0 mm。

Power plant smoke stack in the process, as a result of changes in working conditions, flue gas temperature between 40 ~ 150 ℃, the incident state will exceed 180 ℃, or even higher, and therefore requested the anti-corrosion material has excellent heat resistance.

电厂烟囱在排烟过程中，由于工况变化，烟气温度在40~150℃之间，事故状态下将超过180℃，甚至更高，因此要求防腐材料具有优良的耐热性。

The concrete steps are: the lactic acid and small-molecule dicarboxylic acid react under the condition with the presence of the catalyst to directly polymerize the carboxyl-terminated lactic acid prepolymer; then the aliphatic polycarbonate diol and the catalyst are added; with the presence of the N2, the reaction is kept for 1 to 10 hours at the temperature of 150 to 200 Celsius system to get the poly lactic acid and polycarbonate copolymer of the low molecular weight; then the reaction is done in the twin-screw extruder at the temperature of 150 to 190 Celsius system to screw out the extension chain; finally the polylactic copolymer of the high molecular weight, toughness and heat resistance is made.

具体步骤是：乳酸和小分子二元酸在催化剂条件下反应直接缩聚合成羧基封端的乳酸预聚物，然后加入脂肪族的聚碳酸酯二元醇和催化剂，在N 2 气氛下，抽真空，在150～200℃温度下，反应1～10小时，得到低分子量聚乳酸/聚碳酸酯共聚物，然后在双螺杆挤出机中在140～190℃下，进行反应挤出扩链，最终得到高分子量的、韧性与耐热性较好的聚乳酸共聚物。
