Did you break the thing from plastic? Do not despair! After all, it is subject to repair, whether it is children's toys, or building material, the bumper of your car. If necessary, you can always put plastic. Of course, the former type of the thing will not have no longer, but does not lose its functionality. The main thing is to choose the right glue.
1
To glue plastic, you first need to deal with the composition of the material itself. On many plastic things on the reverse side there is a special cipher that is applied during production. From this labeling and it is necessary to proceed when choosing an adhesive substance. There are types of plastics that are not refundable, for example: Teflon, modern polyurethanes.

So, you figured out, with what kind of plastic is dealing with. Now is the time to purchase materials in order to glue it. As a rule, with such a work, use:
Glue "moment" ("second", "minute");
Weicon substance;
UHU;
Strong or Power Plast;
Quick-drying AKFIX;
Sintex;
Bakelite varnish, BF-2, BF-4 and others.
Glue be sure to purchase in a proven place, use only high-quality products. Pay attention to the shelf life of goods when purchasing, the final result depends on it.

If you work with cool curing glue, then you should know that it adversely affects the surface of the plastic. This is especially true of those materials that are operated in a wet environment and elevated temperatures. Therefore, to achieve the maximum result, it is better to use the heating of the adhesive substance. In this case, polyurethane, epoxy compositions (for example, BF and BS) are gaining relevance.

When working with thermosetting polymers, thermal processing is required. For such materials, a rubber-based adhesive can be used or furan and cyanocrylate substances. It is very profitable to apply a piece of the same material to work with thermoplastic, heated to a viscous substance. In this case, the product is carefully "melted" in a short time. You can also choose the blending option with a brass cabinet. Apply glue with a thin layer, let dry at least an hour, then repeat the procedure. After that, squeeze the product with clamps and put in the oven at least 1 hour at a temperature of 80-100 degrees (depending on the type of glue).
If you can not figure out than glue, use universal glue in the work, which is suitable for all types of connections. Of course, while the quality of work is lost, but you can lead the product in the former look.

Before proceeding with the work, treat the surface of the product. It is important that it was dry and clean. Degrease the surface with sandpaper. It should not be overdoing with the material load. Next, apply glue, with the most customizing the edges of the cracked plastic. In the paper, use a medical syringe or thin brush, you can also do this using a special sprayer or select the "Detail Immersion Method". In order for the product to be glued to qualitatively in a short time, practice exposure under pressure. It is advisable not to touch the material until complete drying and the formation of the solid layer of glue.
Remember that plastic is very toxic. If for some reason you have decided to throw away the unnecessary product, then the best way to recycle is recycled. To upload or process it on its own strictly prohibited. It can harm you and the environment.
