嵌缝石膏配方，各路大神来提提意见！！

[marcogod]

脱硫石膏50%，7#石英砂50%，HPMC 2KG，淀粉醚0.6，缓凝剂0.8， 不用重钙是怕会有收缩性，欢迎大神拍砖！！

 

[Gypsum Plaster]

For joint filler, you should think about the below things:
1. water retention
2. setting time
3. the adhesion with the paper tape
4. sagging problems and workability

如楼上所言，还是要特别注意其施工性和应用用途
嵌缝石膏没有必要放这么多的纤维素，还有就是用脱硫石膏并不一定合适啊
