frothpak/touch n'foam闭孔喷雾泡沫

lornec10|发布能源效率和耐用性

Hello,

We have rim joists to insulate and I’m hoping to do it myself.

FrothPak has a frothpak insulation and a frothpak sealant. They both list rim joists as an option. Does it matter which one I use? I think the sealant is only for penetrations and junctions but the insulation can do double duty.

另外,关于Frothpak与Touch N'Foam有什么建议吗?

同时,环境空气温度上的任何评论required and how much wiggle room there is?

    我知道2个组成部分Frothpak是挑剔的。坦克本身必须在施用期间温暖。如果不是,则“ A”储罐和“ B”储罐的相对排放速率可能会改变并产生不良的混合。我看到了很多装有一个空的坦克的套件,而另一个坦克中仍然有大量的材料。这些摇摆不定的空间。您必须非常遵守他们的申请准则,以获得令人满意的结果。

      Thanks, John. Any knowledge of the "sealant" vs insulation for Rim Joists?

        我不熟悉他们的“密封剂”产品。

    我不确定Frothpak密封胶是什么,但是我不久前买了一个隔热套件 - 然后在我使用它之前就害怕自己(在俄亥俄州附近,想要在Frothpak套件上有很多交易?:P)

    仔细阅读说明和MSD。正确的事情很棘手,在建议的应用条件下,我不会假设摇摆不定的空间。确保您有一个带有适当过滤器的真实交易呼吸器(例如,半面或全脸,而不是防尘口罩),良好的手套,理想情况下是全身西服和良好的通风。其中一个基本上是MDI的水罐,正如Wikipedia所说,“通常是常见异氰酸酯的危险,但不是良性的。”关于二异氰酸酯的一件讨厌的小事是,它们是使剂的敏感性 - 有时暴露(甚至是皮肤暴露)会大大提高您对未来暴露和/或基本上引起哮喘的敏感性。哦,吹剂是R-134A,其全球变暖潜力约为1400。

    我记得从应用程序说明中记得,您基本上还需要在开始后立即准备好Gogogo。如果您停止喷涂超过几秒钟,则需要更改枪支上的尖端,因为它会在尖端中设置。您需要确保混合物恰到好处,否则它无法正确治疗(理论上是自动喷洒合适的混合物 - 但这可能取决于应用温度正确!)

    绝对可以安全地做。我已经需要所有PPE,并且有一个值得信赖的朋友,他也拥有所有必要的PPE和尊重安全的朋友。但是,最后,我决定为什么当还有其他方法可以完成我需要做的事情时,会弄乱如此多的风险。不过,我不是要告诉您不要使用它 - 只是不要以与一罐伟大的东西相同的方式看一个2部分的喷雾泡沫套件(顺便说一下,这也是diisocyates-in-a-a- 可以使用良好的通风,它的规模不完全相同,并且不使用高GWP吹式剂)。

    编辑:显然,他们最近将泡沫绝缘材料的配方更改为无GWP / HFC无吹风剂。Glad Dow做出了这一更改!如果您决定使用此版本,请寻找新版本。不过,我对安全的其余问题仍然存在。

      Thanks for the reinforcement of a full body tyvek suit! No skin exposed! I don't like messing with things I can't pronounce.

    在开始工作之前,至少几个小时让两个坦克保持温暖。在工作中,我将它们放在变压器的顶部过夜。我把它们放在带有太空加热器的浴室里,门也关门了。理想情况下,您希望它们温暖,但不要热,但通常意味着在80-85F范围内。重要的是要将它们保持在该温度几个小时,以便内部的材料完全变暖。坦克会在使用时冷却。在使用过程中,坦克在使用过程中不会太冷,或者您开始​​遇到没有所有材料的问题,或者在极端情况下混合的问题非常重要。

    您需要为应用程序提供额外的喷枪提示。在小费堵塞之前,您几乎没有在喷雾之间喷洒的时间很少。您必须快速工作。我建议在开始之前准备好所有准备就绪的东西,然后计划在开始之前要做的事情,然后在开始时,去做,去完全完成。没有停止,没有休息,只有喷洒,直到完成,只要清楚地移动到另一个位置,尽可能快地移动到另一个位置。开始时也可以拖动坦克,因为它们启动时并不轻巧。

    I recommend some protective equipment. A respirator (a real one with filters, not just a mask) is a good idea, but be sure to use the correct filters for the materials you'll be working with. A full tyvek suit is also a good idea, and you need eye protection.

      谢谢,比尔!给坦克有足够的时间温暖是有道理的。我会在温暖的空间里给他们足够的时间。您听起来好像我还应该准备在施用过程中保持坦克保持温暖。也许我找到了加热的毯子之类的东西。我要借用太空加热器,并将地下室保留给涂抹器的建议。新英格兰现在很冷,因此,我整个夏天都忽略了更好的隔热材料。

      I will GO GO GO. Good tip on dragging the tanks and their weight.

      我都有ppe。这些东西听起来不愉快。

      Do you have suggestions on the froth pak sealant vs the insulation? I have a question out to the manufacturer but the local store has only sealant.

      Thanks.

        A blanket on the tanks is counterproductive. The tanks get cold during use from expelling the material inside. It’s similar to how a can of canned air gets cold when you use it, or how a propane tank gets cold while running your grill. The tanks essentially suck heat from the air around them, and a blanket will reduce that.

        绝缘与密封剂可能是命名的变化。我会与制造商核对。

        The material isn’t super hazardous, but it’s extra super sticky and you don’t want it to get on anything it should, such as your skin. Imagine a high powered squirt gun filled with super glue. That’s essentially what you need to defend yourself from.

        顺便说一句,值得与喷雾泡沫承包商进行检查。您可能会发现承包商不比套件贵得多,尤其是如果您可以灵活地安排您的项目,以便承包商可以在更大的工作之间挤压您。

        One last thing: you get the best results when the surface you’re spraying against is above 50F. If the surface is too cold, you can have problems.

      增加比尔的出色建议:

      A 300 BF kit weighs about 120 lbs. Unless you can do the whole job without moving the tanks you need to figure out how to move them. I used a 4-wheel cart, like a kids red wagon but bigger. This was also the perfect height for standing on to get into the corners of the rim joists.

      I found it helped a lot to hold a rehearsal before spraying -- walk through the whole job with the nozzle in your hand. This helps you plan a route where you can spray continuously. One of the things I learned in rehearsal was my wagon needed to be backed into the corners .

      可能发生的最糟糕的事情之一是,其中一个坦克倒塌了。您只会得到推进剂,您的混合物将会关闭,很难再次正确。将坦克绑在货车上。

    > We have rim joists to insulate and I’m hoping to do it myself.

    Why?

    我也想过自己也想做这件事,但幸运的是多次说话。

    这些套件真的不是那么便宜。当您考虑学习曲线,准备/站点保护,PPE和您的时间时,您会发现在卡车上使用适当的喷涂钻机租用经验丰富的喷雾泡沫安装程序是有意义的。

      Yeah, my experience is that the cost per board foot is less with the guy on the truck. The DIY kits only make sense when you have too small of an area to make it worth the guy's while.

    我一直在使用Frothpak绝缘套件。该版本有较大的版本(650),并且是闭孔泡沫。不知道为什么他们出售两个不同的版本。Frothpak的喷嘴非常好。我会推荐它们,即使它们的成本更高,我也会推荐它们。如果组件不正确混合,您的手上可能会弄得一团糟,浪费了材料。

    I'd also highly recommend heating the tanks in hot water especially if they have the hoses attached. When using a space heater, one of the hoses melted and started leaking on me.

  6. bob7||#13

    Personally, I've used a heating pad in a cooler to keep the tanks warm. You can put the tanks in hours before you want to start, set the pad to medium or low (it depends on the heating pad, of course). Then just move the cooler around....

  7. plumb_bob||#14

    All good advice. I just decided to not use a DYI froth pack!

    Why not cut 2" foam board to press fit then go back with canned foam to seal? More work but safer and less consideration for temps and stuff.
