产品用途：琉璃铸造石膏粉

铸粉专门为琉璃工艺品的失蜡铸造工艺而设计

产品特点

1.铸粉采用高纯度的精选原材料配制而成。                                                                                                                   
2.铸粉易搅拌混合，所成浆液流动性极好空气不易侵入和形成气泡。                                                                               
3.所得铸件表面光洁，尺寸精准。                                                                                                                                       
4.铸粉所成模型能耐850-1000°C高温，可待琉璃完全熔融后浇注。                                                                                   
5.铸粉所成模型经受琉璃在温度升降过程中膨胀收缩的性能极佳。                                                                                     
6.铸粉所成模型与琉璃铸件极易分离，且不会对铸件产生损伤。                                                                                     
7.包装大小为，25kg小包包装。

操作说明

1.精确称取AX-558铸粉和量取净水，粉/水=100/33-36                                                                                                               

2.机器搅拌2分钟                                                                                                                                                            

3.抽真空1.0分钟，祛除气泡，适当地震动有利于清除气泡                                                                                                  

4.浆液注入钢铃至高出蜡模10毫米，再次抽真空1.5分钟

石膏模干燥周期说明

    将石膏模静置至少3小时，之后升温进行失蜡2-4小时，注意失蜡时间不要过长，否则将对石膏模产生损伤,将经失蜡处理装有琉璃碎片的石膏模置于炉中，以每小时50°C的速度升温至850°C，并保温大概30小时（视石膏模大小而定），之后以每小时8°C的速度降至室温。
