Dissolution of plastics is generally carried out for bonding of multiple parts, made of one type of plastics. These include plastics based on polyvinyl chloride, polystyrene, etc.
Use solvents. During processing the bonding surfaces with a solvent is a natural softening when gluing small enough pressure. In addition to solvents, for this purpose you can use the solutions of bonding polymers.
Before connection, prepare the surface of the plastic, for which it was degrease and treat fine sandpaper.
Apply glue so that the softening occurred along the entire working surface to a depth to provide a solid joint. Apply the adhesive with a syringe, brush, spray or dip.
Press the bonding parts and fix them. The pressure on the surface of the show until then, until a solid adhesive layer.
Recently created a lot of new solvents is not less effective than dichloromethane, but, unlike him, is absolutely safe. By the way, this glue can be made at home by mixing plastic shavings with a solvent. To do this, pour into a metal or glass jar plastic chips, shavings or pieces of ABS plastic, mix with solvent WD-40, approximately 2 cm above the level of the plastic. Mix all and cover the mixture for a day, and then again stir it. If the glue is thick, add solvent.
You can also prepare adhesive based on methylene chloride. This will require only 4 hours. You should know that certain plastics corresponding solvent. For example, for celluloid is acetone, polystyrene – benzene, and organic glass – chloroform.
When working with dichloroethane caution as it is very toxic. There should be good ventilation.
Advice 2: How to make plastic
Plastics in the home can be easy and fun to implement, using whatever tools were on hand. And due to the fact that one of the necessary materials to make plastic – Styrofoam – you also help the environment with their experiences as secondary use of non-degradable materials.
You will need
- - acetone
- - glass container with lid
- - Styrofoam
Remove the lid from the glass container and pour in a small amount of acetone (approximately 1.25 cm from the bottom). If need be, add more later.
Break the Styrofoam into small pieces and throw them in a container of acetone. Material in contact with the liquid will begin to dissolve. If you need to get more plastic – just add a little acetone, and then crumble more styrofome.
Wait about 5 minutes to allow the excess acetone to evaporate. If you want to give the plastic some form, wait an extra minute – by this time, the plastic will be easy to succumb to the moulding. Plastic ready, you can sculpt.
Advice 3: Than to dissolve the glue
Removing glue stains is quite a daunting task and the quality of the composition and is difficult to clean from surfaces on which it is intended to be held firmly. To get rid of the glue by dissolving the stains, using various physical and chemical solvents. But which one is most effective?
The universal solvent of natural origin is water, which can be used to remove stains from carpentry, vegetable, stationery and PVA glue. To do this, quickly wipe a fresh stain with a rag and rinse soiled area (clothing, upholstery or other surface) until complete disappearance of the glue residue.
If the adhesive spot has long been hopelessly dead – remove it with water is not possible.
Well established in the dissolving glue of vegetable and baby oil, any of which must abundantly lubricate the stain, leave it for a while, and then re-RUB the oil into the glue. He will begin to lose their adhesive properties and are mixed with the "solvent", as some glues prepared oil-based. After treatment stains leftovers are removed, and the surface is rinsed with water.
Can dissolve the glue and plain vinegar. You need to apply it liberally to the stain and wait 20 minutes. The glue will begin to dissolve, and its remnants can easily be removed with a cloth. An effective solvent is the paste of baking soda, cooked in a simple recipe - tablespoon of baking soda with one teaspoon water. This mass should be applied to the stain, wait until it dissolves and rinse with warm water. A similar effect is known for, and vaseline, fat which breaks down the molecules of the adhesive.
A perfect solvent is alcohol, which breaks down and dissolves many of the glued joints. After applying the alcohol to the old glue stain after a few minutes it will begin to soften. After that glue residue is easily removed with water and rags. Similarly, the action has acetone, which is necessary to moisten a cotton swab and place it on the stain. After a few minutes the glue will dissolve and it will be possible to scrub an old toothbrush.
The acetone must be carefully use on some synthetic materials, as it can damage them.
Well dissolve the adhesive substances such as gasoline, turpentine, mineral spirits, paint solvent or ammonia. Use them as well as acetone, but to facilitate the removal of the glue before applying the solvent can be softened with the included hair dryer. After that it will dissolve much faster and more, and at the end of the spot, you can gently scrape off the convenient assistant the subject.
