solvent welding การใช้

• The " gluing " together of plastic ( polycarbonate, polystyrene or ABS ) models is also a solvent welding process.
• Unlike metal welding, solvent welding is relatively easy to perform ( although care is needed to make reliable joints ).
• Polyolefin surfaces are not effectively joined together by solvent welding because they have excellent chemical resistance and are unaffected by common solvents.
• Solvent welding is usually used with a sleeve-type joint to connect pipe and fittings made of the same ( or compatible ) material.
• A common use for solvent welding is for joining PVC or ABS ( acrylonitrile butadiene styrene ) pipes during plumbing, or for welding styrene and polystyrene plastics in the construction of models.
• Solvent welding is especially effective on plastics like PVC which burn at or below their glass transition, but may be ineffective on plastics like Teflon or polyethylene that are resistant to chemical decomposition.
• Pipe normally has thicker walls and may be threaded or welded, while tubing is thinner-walled and requires special joining techniques such as brazing, compression fitting, crimping, or for plastics, solvent welding.
