determine the composition of the plastic, which is going to be repaired.This is extremely important, for each type of material scientists have developed a special glue.For example, polyethylene, you can just glue a special compound that changes the structure of the surface of the reca
lcitrant material and increases its ability to adhere to other items.And for others, you will need plastic epoxy resins, solvents or other mixture.
Note that the quality adhesive must not only provide good adhesion (adhesion) plastic surfaces, but also to resist violent shocks and sudden change in temperature and humidity.Consult with a competent manufacturer of building materials store!
Just stick to the manufacturer's instructions.Typically, the plastic parts to be bonded should carefully handle fine sandpaper and clean them from dust and other contaminants.For degreasing wipe material with a cotton swab moistened it in acetone.Instead, you can use a special cleaner for plastic masses.
prigonyat firmly glued parts to one another.For the quality of the fit is necessary to check the purity of the finger processing sanded surface to prevent bumps and irregularities.
Give leveled and cleaned plastic dry completely.Then apply glue to it with a small brush or spray.Following the example of experienced craftsmen, for narrow gaps can be filled with adhesive composition used a disposable syringe.
strengthen large cracks and chips in the leaky plastic can use fiberglass or reinforcement stitches priplavlennymi (glued) stripes of dense fabric.Thermoplastic (ie weight, are easy to heat treatment) can be pre-softened soldering iron or hair dryer building and apply a layer of fine metal filings.
very strongly press the plastic parts with a special holder (clamp) or press.Make sure that when this portion of the article is not broke!Usually it is recommended to keep the pressure of not less than one hour, although the duration of the process depends on the material and temperature conditions.So, when heated thermoplastics enough to withstand the product under pressure for half an hour (until it is cool, and the adhesive is cured).If you kleite plastics without heat treatment at room temperature, then it must lie at least half a day before reuse.
If you want to quickly and efficiently seal the plastic mass from the category of thermoplastics, try to do it without glue.Operate soldering or welding machine.You can make a strong seam, soldered into it a reinforcing material.
