At insignificant damages of product from plastic it is possible to try it to stick. In work with this material as the most important factor of success there will be right choice of the gluing structure. Usually on plastic reverse the producer specifies its marking. Surely study characteristics of this material, otherwise the result of repair will disappoint you. Pasting of plastic is the real science therefore do not scorn opinion of experienced experts and attentively study glue application instructions.
It is required to you
- - glue for plastic;
- - acetone or cleaner for plastic;
- - bathing tampon;
- - abrasive paper No. 1000;
- - brush, spray or syringe;
- - soldering iron or construction hair dryer;
- - armature (if necessary);
- - clamp or press.
Instruction
1. Find out composition of plastic which you are going to repair. It is extremely important as scientists have developed special glue for each type of this material. For example, you will be able to stick together polyethylene only special structure which changes surface structure of this rebellious material and increases its ability to be linked to other part. And epoxy resins, solvents or other mixes will be necessary for you for other plastics.
2. Consider that quality glue has to not only provide good coupling (adhesion) of plastic surfaces, but also resist strong mechanical influence and sharp change of temperature and humidity. Consult with the competent seller of shop of construction materials!
3. Precisely adhere to the instruction of the producer. Usually plastic parts before pasting are recommended to be processed carefully fine-grained abrasive paper and to clean them from dust and other pollution. For degreasing wipe material with cotton tampon, having moistened it in acetone. Instead it is possible to use special cleaner for plastic masses.
4. Densely drive adherend parts to one another. For quality of adjustment it is necessary to check finger purity of processing of zashkurenny surface not to allow hillocks and roughnesses.
5. Let's the leveled and purified plastic dry completely. After that apply on it glue by means of small brush or the spray. By example of skilled masters, for narrow slots it is possible to use the disposable syringe filled with the gluing structure.
6. It is possible to strengthen big breaks and chips on leaky plastic by means of fiber glass, or reinforcing of seams the priplavlenny (pasted) strips of dense cloth. Thermoplastic (that is the weight which is easily giving in to thermal treatment) can be softened previously the soldering iron or the construction hair dryer and to apply on it layer of small metal shavings.
7. Very strongly press plastic parts by means of the special holder (clamp) or press. Watch that at the same time parts of product have not dispersed! This pressure is normal it is recommended to continue not less than an hour though duration of process depends on specific material and temperature conditions. So, when heating thermoplastics it is enough to sustain product under press within half an hour (so far it not to be cooled, and glue will not harden). If you glue plastic without heat treatment at the room temperature, then she has to lie down not less than a half of days before further use.
