还有一种是整体滾动注塑.
嗯也许 滚动注塑 可以有几个chamber

Make sense, 没想到是因为制造工艺的限制，我还以为是便于放鱼杆之类的。
但是这样的话，万一有个大洞就没救了。

不用大洞，水面以下针眼大的小洞都是致命的。

我也以为SOT不会有沉危险，学习了。

I was just thinking about this. Do you know if it was done before?

I once talked 司令 to go through this process for his SIT....I believe it didn't happen

不知道这个泡沫比重多少哈

Sergeantpepper @ Sun Apr 26, 2020 3:55 pm 写道: 密度跟K Factor , thermal conductivity, 有关, 一般雪柜,冷庫用的就差不多1lb/cu.ft.
这种把resin 和 polyol pre mix 的没见有参巧数据, 像上面造艇那种带structural strength 的會比較重...
我有种省錢想法, 就是把切成适度小块的白色 styrofoam 跟这PU foam 混和一起用

我觉得用airbag比泡沫会好一点，easy to undo or redo。

Sergeantpepper @ 26 Apr 2020 18:30 写道: air bags are not as reliable as solid closed cell foam blocks,
of course you may argue that the chance for all air bags to burst at the same time is very unlikely....
to stuff the air chambers with Pool Noodles is an alternative, they are made of closed cell PE Foam
why would one plan to undo these buoyant media anyways ? they are meant to be permanent

Sergeantpepper @ 26 Apr 2020 20:36 写道: foam-in-place PU will fill up all space and leave no room/passage for water, moisture etc

If Im in the trade I definitely will consider "foam-it-up" as an add-on/optional feature for SOT & SIT-IN kayaks
