You will definitely use this trick if you didn’t know it before. We will talk about how to very reliably glue plastic or plastic parts with ordinary second glue, using one small secret, which increases the strength of the connection of two parts by more than 10 times.
What's the trick?
So, the secret is that around the seam of the parts to be glued we will apply ordinary soda with superglue. The result is a very strong thickening around the seam.
The fact is that the cyanoacrylates that make up the glue interact with soda. They interact and are not just a filler. When these two components are mixed, an instant reaction occurs and the strongest composition is obtained, which can be used to glue not only plastics, but also metals. A kind of cold welding. Second glue by itself is not half as strong when used alone. It is not surprising that everything they did did not hold up well and fell apart. But with the use of this technology, this will no longer happen.
Will need
- Any super or second glue.
- Baking soda.
Gluing plastic
Let's get started.The bushing into which the screw is screwed has broken off. And, accordingly, I will now restore all this.
At the beginning everything is as usual. Lubricate the area with glue.
One and the other have details.
Let's connect them.
Now the soda comes into play. When the parts come into contact, excess glue is squeezed out; it needs to be sprinkled generously with soda.
After 5 seconds, the excess can be blown off.
Then pour superglue generously around the crack and immediately cover it with baking soda again.
We blow off the excess again.
We repeat the process again.
Sprinkle generously.
As a result, a strong bead has formed around the bushing, which will hold everything securely.
Although everything has hardened before your eyes, it is recommended to let it sit for about 24 hours before using the product.
Pros and cons of the method
Pros:
- Instant hardening. Even large drops freeze immediately.
- The end result is a very durable monolith.
- Glues almost any plastic.
- You can even seal holes and holes.
Minuses:
- Instant hardening can act as a negative factor due to the fact that the composition cannot be poured into the center of the parts to be glued.
- The reaction occurs with the release of heat, which in some cases can be negative.
- Unfortunately, such a composition can only be applied to the surface, but there are times when it is not possible to reach it.
I especially recommend that motorists take note of this recipe, since I myself have glued dashboards and filter glasses using this method more than once. Holds tight!
