I glued the breakage with a superglue with salt. Turned out as durable as with baking soda

I propose to evaluate another way of affordable, inexpensive and durable gluing of various breakdowns, which suggested in the comments to the article Glued the breakage with baking soda super glue. I explain the secret of the gluing speed and strength of this adhesive mixture one of the readers. He wrote that the same effect of strong adhesion is achieved with the addition of edible salt to the seam.

I decided to check this method, I hear about it for the first time. Although I know about adding soda when gluing with superglue for more than 10 years.

I tried to glue a plastic ruler. There were no other breakdowns at hand. If you just glue it with super glue, then there is no certainty that it will not break again in this place. For convenience, I poured some table salt into a measuring cup. Although it is finely ground, it is larger than soda.

First I glued the halves of the ruler, waited for the glue to gain strength, then spilled the seam with superglue again and sprinkled it with salt. Surprisingly, almost as quickly as with baking soda, the salt quickly turned into a monolith. Cyanoacrylate (a superglue chemical) requires moisture to harden. And salt always contains it. It turns out that salt acts both as a filler of the glue mass (like crushed stone in concrete) and as a catalyst (accelerator) of the polymerization process.

I did the same with the second side of the ruler. Cutter's ruler for working with fabric. And an absolutely smooth surface is not important to her.

I tried to bend the ruler after the glue dries. Folds like new. I did not break it to test the strength. I just made sure that this salt and super glue seam is also strong.

If you haven't found baking soda at hand, but something needs to be glued securely, then the method of gluing with salt is also good. The adhesive material is durable. Readers wrote in the comments that lime, plaster, and plastic sawdust are also suitable as fillers for superglue. All this acts as fillers and gives great strength to superglue.

The disadvantage of the salt method is that the salt crystals are still large. Something large cage is normal, but a miniature one is not very good. It would not hurt to grind it into powder beforehand.
