What should I do if the water glass and plastic fake flowers are not sticky?

What should I do if the water glass and plastic fake flowers are not sticky? PBT can not be bonded with epoxy resin, it is an inert surface like PP, the correct resin for grafting should be PA or CPP (polyamide, chlorinated polypropylene), PBT should be primed with silane coupling agent, then adhesion promotion layer, and finally glued to other workpieces you want to bond. Epoxy resins can only bond non-olefin plastics.

Before bonding, do a good job of surface grease removal, it is recommended to use generally not directly added to the epoxy resin component, adding to the epoxy resin component will shorten the storage period, the most common phenomenon is to add E51 epoxy resin to cause E51 epoxy resin to slowly become opaque, crystallized, agglomerate.

The landlord's title is also weird and funny, what should I do if it doesn't stick or not? Non-sticky of course not sticky, hehe. Solution within:

1. Roast it over a holding fire.

2. Brush the bottle with alcohol and stick it again, but quickly.

3. Soak it in banana water before sticking.

Too much humidity or heat can affect viscosity.

If you have plastic products, you can just put them in the microwave and heat them in other ways! For other metal products, use 502 glue!

First of all, the glass bottle should be cleaned, the oil and dust should be removed, and then the moisture should be removed (fire), and the self-adhesive should be heated and pressed after sticking.

502 will be corrosive Water glass is a liquid state of sodium silicate, which is mostly called water glass in the south and bubble alkali in the north. Sodium silicate is commonly known as water glass, and liquid sodium silicate is a colorless, slightly colored transparent or translucent viscous liquid. Solid sodium silicate is a colorless, slightly colored transparent or translucent glass block.

There are three forms: liquid, solid, and water quenching. Theoretically, such substances are called "colloids".

There are several kinds of materials that need to be sprayed primer, such as ABS can be sprayed directly, such as PP to spray special primer, I don't know what kind of plastic you use?

Depending on the reaction in your basin, generally if it is not very violent, the plastic basin should not be burned.

Caustic soda can only corrode aluminum basins, not plastic basins, for fear that the temperature inside is too high and the plastic basins will be burned.

It's not poisoning, it's a small amount of lime getting into the nose, and you'll be fine with a mask.

Good afternoon, PBT can not be bonded with epoxy resin, it is the same inert surface as PP, the correct resin for grafting should be PA or CPP (polyamide, chlorinated polypropylene), and the upper Hu sedan PBT should be primed with silane coupling agent, and then the adhesion promotion layer, and finally the other workpieces you want to bond. Epoxy resins can only bond non-olefin plastics. Do a good job of surface degreasing before bonding, and it is recommended to use CPP.

Let's try it first.

The same size, the one that is dense, the one that cools down quickly.

The glass bottle is dense, the heat transfer is fast, and of course the water in the glass bottle cools quickly. Plastic ones should be slow.

For example, if it is foam, it is slower because the foam density is too small.
