如何含有声学密封剂毒素？
Acoustical sealant was applied to tu-tuff as the vapor barrier for our crawl space.
This was phase one before going to phase two which would be use the supply and return
air sources to ventilate the area. The sealant was only used to adhere the vb to the concrete foundation wall. The sealant is superior becomes it does not dry out; hence, it maintains a seal
for radon remediation as well as a vb.
但问题是，密封胶是有毒的并且没有治愈。安装人员实际上变得不生病，不得不在第一天戒烟。他回来完成工作，但不是很开心。此时，我正在等待他的回归使用最大强度鸭胶带来密封VB外围的基础。他开始了，但耗尽了磁带。
Meanwhile, five days later, the vapors are still very strong. The laundry area adjoins and my wife reports feeling a loopie if she remains too long.
我踩到了这一点，想我正在做正确的事。我想是“绿色”并不一定意味着安全。在这一点上，我认为我可能需要放弃理论上的应用，这些理论被称为您的爬行空间作为您的家庭，并绑架竞争理论，该理论要求将其视为您的阁楼与生活空间避免，并提供通风。
有什么建议？是否有经过验证的方法，该方法在其中一个爬行空间和另一个爬行空间和被动通风口处具有排气扇。缺点是爬行空间不会对极端温度和湿度开放。我们住在肯塔基州北部地区。
更乐观的......。几周后，密封剂停止缓和的东西？

威廉，
You raise several issues.
我不相信声学密封剂的烟雾有毒，尽管有些人可能对气味敏感。
2.有几种方法可以将空气与上面的生活空间中的空气分开，我将在下面描述。
3. You can use a high quality European tape (like Siga Wigluv, which is available from小星球车间），将聚乙烯密封到您的爬行空间壁上。
I urge you to read建立一个不经常的爬行空间。The article describes two ways that a sealed, conditioned crawl space can meet code requirements. The method that would make the most sense for your situation would be to install a small exhaust fan in the crawl space (to depressurize it) along with a floor register that allows conditioned air from the upstairs to enter the crawl space, replacing the air that is removed by the exhaust fan.
It's also possible to leave the crawl space unconditioned, and to avoid any connection between the crawl space and the house above. This approach requires a high degree of air sealing and attention to duct tightness. You also need to monitor the humidity level in the crawl space to be sure it stays under control. In some locations, this approach might not work.
Martin,
Thank you for the rapid response and suggestions for ventilation. I am totally on board with trying
减压爬行空间。如果我们可以保持最小的负压，如果我有术语正确，到外面，我认为我们将完成我们的目标。而不是建议的地板登记簿你会怎样涉及留下一个小区域，其中地下室接口爬行空间？目前，接触墙几乎到了楼上的楼梯顶部，我们有一个开放的楼梯（从一楼没有地下门）。实质上，爬行空间外墙上的排气扇有机会可靠地从楼上的空气中拉出空气。因此，我正在考虑使用Roxul或刚性反射箔绝缘的东西，以密封爬行空间，除了为大约一英尺六英寸的区域。听起来好吗？
As for an exhaust fan, do you have opinion as to whether or not it should be continuous vs intermittent? The only reason that I can think of for intermittent is that maybe a continuous mode iwould over tax how much air is available to be drawn in from outside. Another detail is how strong of an exhaust fan? Would 50cfm be too little? The area of the crawl space is about 700 sq ft. I'm currently looking at the Panasonic Whisper line of exhaust fans, normally used for a bathroom.
毒性的声学密封剂,盒状态s in rather strong language that the off gassing is very toxic. (Tremco is the brand.) And, the contractor looked and said that he didn't feel too well even when he came back the second day to do some additional taping. He's a pretty tough dude. I suppose that over an additional time period there might be a crust that forms but I think this stuff stays very gooey.
欧洲录像带是个好主意。也许是线的顶部......最大力量鸭胶带......工作一半，但可能没有您引用的粘附中的厚度。
I'll call tremco and see what they have to say.
威廉，
Q. "As for an exhaust fan, do you have opinion as to whether or not it should be continuous vs intermittent? ... Another detail is how strong of an exhaust fan? Would 50 cfm be too little? The area of the crawl space is about 700 sq ft."
A.可以在我敦促您阅读的文章中找到您的问题的答案：建立一个不经常的爬行空间。在该文章中，我写道：“代码列出了两个用于调节未辩护的爬网空间的选项;两种选项都需要安装与楼上的条件空间连接爬网空间的管道或转移格栅。选项1要求'连续操作的机械排气通风每50平方英尺的爬行空间地板区域的速率等于1 CFM。“
根据该公式，所需的通风率为14 CFM。
