At breakage of any plastic parts many try to repair them independently. However not at all it turns out. As when choosing way of connection it is necessary to consider rheological properties of plastic and their type: easily welded, hardly welded or to what we will not apply way of fusion welding at all.
Instruction
1. Many try to melt plastic piece in pan on water bath and then to fill in and connect seams. At the same time the surface can be deformed, and the seam will be not reliable and short-lived.
2. In attempt to alloy plastic fragments the soldering iron, be very attentive as melting temperature in this case will be exceeded and the seam will be brittle and fragile.
3. It is better to use special electric gun which melts plastic. Together with gun it is necessary to buy also plastic bars by means of which there is zaplavleniye of seams.
4. It is possible to use the professional or semi-professional hair dryer, with continuous adjustment of temperature and air flow. In addition you will need nozzles for welding. For this purpose it is necessary to smooth out both parties of weld. Pick up welding rods for structure - fragment similar to material. Whenever possible make welding test for check of compatibility of materials and also for selection of necessary heating temperature, motion speed of the hair dryer and force of cave-in. Warm up the hair dryer within 10 minutes that temperature of hot air stabilized.
5. Put fragments of part and fix in the necessary situation with the help of special clamps clothespegs. Sharpen the end of bar to facilitate initial stage of welding. Incline bar at an angle 45 ° during welding, or use nozzle for fast welding. Use of nozzle facilitates welding process as it has the fixed provisions, both for bar, and for the hair dryer. In work press down bar a little. As a result at you the flush joint which is a little towering over surface has to turn out. After full cooling it is necessary to grind seam and to paint if it is necessary.
