发帖数: 217 | 1 家在中西部，最近下大雨发现地下室两个没有装修的closet里面有水从水泥地基最上面
滴进来。请来的contractor说是雨水渗进砖墙导致的。正常情况下外面的砖墙在水泥地
基上面都有一层防水塑料膜，并且每隔1-2米左右就有一个小孔让渗进去或者从屋顶漏
进去的水流出来。但是房子正门那里砌了几个台阶，把应该往外面流的水挡住了，于是
渗进砖墙的雨水就往地下室流了（地下室的那两个closet正好在正门的两边）。他建议
用silane/siloxane把外墙处理一下，这样雨水就不会渗进来了。几个问题想请教一下
大家：
1：他说的原因大家同意吗？
2：地下室是装修的，是不是有砖墙的那一面任何地方都有可能有水进来？需不需要打
开dry wall看一下？
3：Contractor要价$1000左右，但是我们家房子只有正面是砖墙（或者贴砖），是不是
太贵了？
谢谢大家！ |

Happy New Year! 用PDMS作模板，UV+AIBN 聚合vinyl pyrrolidone，问题是PDMS模板
用了几次就不行了，和PVP粘在一起，即使用有机溶剂+加热也难以分开。现在强烈怀疑
PDMS里的dimethyl vinyl siloxanes也参与了UV聚合，请问如何预处理可以去除Vinyl
siloxane？或者如何预处理可以让聚合物从PDMS上顺利剥离？多谢了。 |

发帖数: 5044 | 4 Thank you for the reply. I will look into it. I am thinking about siloxane.
Do you know if any siloxane might fit my interest? |

发帖数: 2934 | 9 it would be safe if the temperature is not too high, The degradation temperature of siloxane polymer is higher than 400 C. so it would be very safe if you never exceed 400 F which is much lower than 400 C. Do you have kohls coupon? I need some. |

but it'll very expensive to dig out the whole basement and re-seal the whole
outside concrete foundation - much more than $1000. for $1000 i guess he
will only dig up a small segment. the question is whether it will fix your
problem if the leaking point is not where he digs out. |

所有的地方都是liquid老大，他们是把siloxane和base按不同比例混在一起得到PDMS的
。没人直接卖pdms |
