发帖数: 3544 | 2 You may not need to remove the inhibitor in acrylic acid. It only has 100-
200 ppm. De-hibit resin contains amine and I don't know if it works on
acrylic acid. It's not fun to run acrylic acid through column any way. |

distillation through a column packed with copper gauze to inhibit
polymerisation. (This treatment also removes inhibitors such as methylene
blue that may be present.) Azeotropic distillation of the water with *

Counterfeit Apple Stores Popping Up In China

one of the stores recently, staffed with blue-shirted employees who believe

发帖数: 2753 | 46 now I am confused. how? There are male acrylates and female acrylates? But
if you are right, then i know why I failed my last polymerization reaction.
They were all male acrylates. Of course when I put them together there was
no reaction.
把arylate分男女就好理解了。

1. 用Onyx Collection, 连工带料7000刀
2. 用tile, 连工带料5500刀
3 用Acrylic / Fiberglass,连工带料3500刀
说是要干4-5天。以上报价都含换shower door.
大家觉得这些报价靠谱吗？
我们现在的是tile,年头长了有水锈。有人装过Onyx 和Acrylic / Fiberglass吗？感觉
怎么样？ |
