You will need
- - capacity for melting plastic;
- - soldering iron or soldering station;
- - gas burner;
- - industrial dryer;
- - welding gun.
Before you start melting the plastic, try it out with a small piece. Not every type of plastic is susceptible to melting under normal conditions, so it is advisable to find out during the experience. A piece of material to grab with forceps or tweezers and hold it close to the open flame of a candle or gas burner. Heated plastic will either melt slowly or immediately begin to burn in the open air.
Making sure that plastic can be melted, chop the source material and place it in a metal container, for example, in a tin can. For the safety of the melting material, a container of shredded plastic insert in another bowl with large size. Fill it with water and put the whole construction on fire or stove, making a kind of water bath. This method is suitable for processing plastic with a low melting point.
To melt small pieces of plastic, use the heated tip of a soldering iron or a gas torch. If possible, use a soldering station with a built-in adjustment of heating temperature of the tip. Need to pick up the melting temperature on the basis of the experiment. Too high temperature may cause ignition of the material or make the plastic brittle.
For melting plastic with high strength use the welding gun or heat gun. The working procedure of welding gun is indicated in the technical documentation. Set includes filler materials for welding different types of plastic and plastic, for example, to fuse the seams of the connected products.
When processing plastic of high temperatures observe precaution. Preferably all procedures are done in the open air to avoid poisoning with burning products. Avoid contact of the melt on the exposed parts of the body and clothing to prevent burns and damage tissue.
Advice 2 : How to melt plastic
In case of breakage of any plastic parts a try yourself to fix it. However, not all succeed. Since the choice of connection method it is necessary to consider the rheological properties of plastics and their type: legkousvaivaemyh, trudnosmyvaemye or those that do not apply the method of fusion welding.
Many people try to melt the piece of plastic in the pan in a water bath and then pour and connect the seams. The surface may be deformed, and the seam is not reliable and not durable.
When you try to fuse plastic fragments soldering iron, be very careful as the melting point in this case is exceeded and the seam becomes brittle and fragile.
It is better to use a special electric gun that melts plastic. Along with the gun you need to buy plastic rods, with which comes the filling up of the seams.
You can use a professional or semi-professional dryer, continuously adjustable temperature and airflow. Additionally you need attachments for welding. It is necessary to clean both sides of the weld. Pick up the welding rods according to the composition similar to the material of the fragment. If possible, make a test weld to check the compatibility of materials, and for selecting the required heating temperature, the speed of the dryer and the force of indentation. Run the dryer for 10 minutes to stabilize the temperature of the hot air.
Fold the pieces of items and secure in position using special clamps-clothespins. Sharpen the end of the rod to facilitate the initial stage of welding. Tilt the rod at a 45° angle during welding, or use the speed welding nozzle. The use of the nozzle facilitates the welding process because it has a fixed position, as for bar and Hairdryer. In the work a little prodavlivaet rod. As a result, you should get a smooth seam, rising a little above the surface. After complete cooling it is necessary to Polish the seam and repaint, if necessary.
