There are many different types of resins and glues, and when you mix them wrong, the bond between them will be weak, or sometimes the glue will damage the object you want to fix. Read on to learn how to choose the right glue for your project, then follow the steps below to get the two things you need to stick together forever. If you need to glue pieces of plastic pipes, you can immediately jump to this section, which contains instructions on choosing the right adhesive for plastic pipes.
Steps
Choose the type of glue
- Lego bricks made from “ABS” plastic are best glued with epoxy glue. Solvent adhesives for ABS plastic can also be used, but may deform the surface of the material.
- Imitation glass, cheap toys, CD cases and similar brittle plastic items are often made from “ppystyrene” so can be glued with some sort of glue. For best results you should use ppy glue or glue that is advertised for use with plastic.
- For hard plastics such as bottles, crates, crates and food containers, you should use a glue that is specifically advertised as being able to stick “ppyethylene” and “ppypropylene” plastics. Most common glues cannot stick these products, so you should not assume that glue labeled “for plastics” is okay to use, unless it is clearly stated as “ppyethylene” or “ppypropylene”.
- Visit This to That page for general advice on the type of glue to use to glue different materials. This advice is most useful for common plastics, especially ppystyrene.
- If you’re not sure if the glue you’ve chosen is correct, try using it to stick a piece of scrap material of the same material, or stick it to a hidden corner of the object to be glued on.
Sequence of gluing plastic
- Then avoid touching the object with your bare hands to reduce oil residue.
- See Choosing a Glue for the type of glue to use. You can skip this step if you are not using two-component glue.
- If using solvent glue ( not ppy glue), you should first clamp the two objects to be joined, then use the pump tube to sweep a line of glue along the edge between the two objects, then the glue will be sucked into the slot. gap between them. [7] X Source of Research If you are using solvent glue for plastic pipes, see the section Gluing plastic pipes.
- Many resin glues continue to “grow in strength” for days or even weeks after application. Avoid applying pressure or heat to two glued objects for at least 24 hours after gluing, even if the two objects appear to be firmly bonded.
Sticking plastic pipes
- PVC pipes are commonly used in homes, although they should not be used as distribution pipes or in applications exposed to high temperatures. This type of pipe is usually white or gray in color if used in electrical or industrial applications. The recycling symbol for this type of pipe is 6 or PVC .
- CPVC pipes are PVC pipes that have been treated to withstand high temperatures. It has the same recycling symbol as PVC (6 or PVC) but is usually light yellow or cream in color.
- ABS is an older and more flexible style of plastic pipe, usually black in color. This type of pipe is not suitable for carrying drinking water, and in some jurisdictions it is prohibited by law to be used as a water pipe. The recycling symbol of the hose is 9 , ABS or 7 (other) .
- PEX is the newest style of plastic pipe and comes in a variety of colors. PEX pipes are not recyclable, cannot be glued, and you must use a mechanical connection tool to attach the hose.
- ABS solvent glue is used to attach ABS pipes together. Solvent-adhesive PVC and CPVC are used to attach pipes made of the same resin.
- Intermediate solvent glue used to attach ABS pipes to PVC pipes. The striking green color of the glue makes it easy to identify.
- If you can’t find a specialized product, all-purpose solvent glue can also be used to join PVC, CPVC and ABS pipes together. First you should still distinguish the type of plastic pipe to rule out the possibility that it is a PEX pipe, which cannot be glued but can only be connected with a mechanical tool.
- Read the label on the glue to make sure the size of the tube you are using can be applied.
- To join a plastic pipe to a metal pipe, you may need to use a special glue that is used to combine the plastic with the metal, or you may need to connect it mechanically. Ask the staff at electrical and water stores and hardware stores for advice.
- Press the sandpaper to the shape of the tube face before sanding.
- If you don’t have sandpaper, use a file or tweezers to cut away any visible sharp edges.
Advice
- Silicone glue is useless against plastics unless it is used for cosmetic purposes only, it is not a solid bonding solution.
- If you accidentally drop acrylic glue on a plastic surface where it doesn’t need to be glued, you don’t need to wipe it off. The glue will evaporate on its own.
Warning
- Always apply in a well-ventilated place or wear a respirator.
