硬塑料怎么粘起来?

有些胶可以，尤其是工业用的。但受力浸水等条件不同，用不同的胶，要google粘合剂，搜索胶水不行

以俺的经验这个基本上就粘不上了

俺也嚼的是, 但是就是想试试看.

昨天已经用502给粘起来了. 但是肯定脆不吃力.

现在正在想加固的法子.

btw: 谁知道那里有买热收缩的塑料管买(1 cm 直径的样子).

I do not know your application. I know some adhesives, especially for water sealing. not all by GOOGLE!

if i suggest bostik 7575 (it's for marine, i planed to use on my skies) or loctite 3211 (for water proof, i dont think it's for your application), you may not understand (I assume) or you do not know where to buy. If you are in Toronto, I can give you some of our samples to try.

some of them for high temperature, for sealant etc. some are expoxy based, some are not. some are instant cure, some need oven to cure. it's too complicated. So I suggest google. I know there are some adhesive are very strong, but it's only for industry usage.

You can also take it to homedepot or just buy a new one, it's easier.

回头晚上我把它竖起来, 照一张.

这个玩艺最要命的是粘结面只有 1毫米厚多一点点, 我角的没有胶能在这个小的创面上产生超过原来塑料本身的强度.


所以我想旁边放点加强筋做辅助, 目前我是这么想的:

1, 背面平滑面用牙膏皮,
2, 内侧牙齿部分用一根粗皮筋

然后用某种材料把它裹起来.

您看行不行?

No, I am not an expert. However, we do use some adhesives in our products, most of them are for sealing (to prevent water intrusion or leaking).

all my experience are based on my company's application or some research I did for my company. Just one of the suppliers, henkel, has more than 1000 adhesives. Most of them are for industries. For your particular requirement, it's depend on how badly you want it to be fixed or the cost to fix it. I dont think you REALLY REALLY need it to be fix and want to pay waterever cost to fix it. So, just bring it to homedepot and ask the salesman there, yes or no, that's it. If you go HIGHWAY, then you can ask your company's buyer to ask for some samples from these componies, Henkel, bostik etc.. Usually, it's free. But you need to do some research and "plot" an application for these companies so they will belive you and give you some samples for free.
