Shading glue is the best, followed by 502.
The glass is broken. What kind of glue is better?
Glass is hard and brittle, and its surface is smooth, so it needs special adhesive for bonding. Mainly AE acrylate adhesive, the scientific name is AE room temperature curing transparent acrylate adhesive. Specifically, there are two kinds, AE-0 1 glue and AE-02 glue. The former is suitable for bonding plexiglass; The latter is suitable for bonding inorganic glass and tempered glass.
This is a colorless and transparent viscous liquid, which can be cured within 4 ~ 8 hours at room temperature, with strong adhesion and simple operation.
In addition, there is a kind of polyvinyl butyral adhesive, which has excellent adhesion to inorganic glass, colorless and transparent, moisture resistance, corrosion resistance, aging resistance and impact resistance. Very strong after bonding. Widely used in interior decoration.
What should I use to break the glass?
Try AB glue, 10 1. I tried, but I can't soak it in hot water. It will open after soaking. It is said that 502 works, but the effect is similar to 10 1. There is also food-grade silica gel (attached to the bottom of the health pot) that can stick to water-tight and heat-resistant water, but it will leave a big lump at the crack. Once I broke a glass and tried to stick it with a lot of glue. I hope it helps you.
What glue is used to bond the broken glass?
The first choice is that the two brothers are good at viscose, and secondly, if the surrounding environment is dry, 502 glue can also be used. The advantage of Gelia glue is that it is firm and stable, but the disadvantage is that it is troublesome and laborious, and the glue marks are obviously unsightly after bonding. The advantage of 502 glue is that one drop is enough, but the disadvantage is that it is afraid of water, and the glue will fail where there is water vapor.
What glue can be used to stick the broken glass ornaments firmly?
Shading glue
Shading glue (uv glue) is also called photosensitive glue and UV curing glue. Shadow-less adhesive is a kind of adhesive that can only be cured by ultraviolet radiation. It can be used as an adhesive and glue for paint, coating and ink. UV is the abbreviation of ultraviolet, that is, ultraviolet ultraviolet (UV) is invisible to the naked eye, which is a section of electromagnetic radiation other than visible light, and its wavelength is in the range of1/kloc-0 ~ 400 nm. The curing principle of shadowless adhesive is that the photoinitiator (or photosensitizer) in ultraviolet curing material absorbs ultraviolet light under the irradiation of ultraviolet light, generates active free radicals or cations, initiates monomer polymerization and cross-linking chemical reactions, and makes the adhesive change from liquid to solid in a few seconds.
General application software
Bonding of plastics to plastics, plastics to glass, plastics to metals and other materials. Mainly aimed at the self-adhesion and mutual adhesion of plastics in handicraft industry and furniture industry, such as the adhesion of tea table glass and steel frame, and the adhesion of glass fish tank, including PMMA acrylic, PC, ABS, PVC, PS and other thermoplastics.
Application mode
principle of operation
In the gluing process of shadowless glue, shadowless glue is also called ultraviolet glue, which can only be cured under the premise of ultraviolet radiation, that is, the photosensitizer in shadowless glue will combine with monomer under ultraviolet radiation, while theoretically shadowless glue will hardly cure without ultraviolet light source.
There are two sources of ultraviolet rays: natural sunlight and artificial light sources. The stronger the ultraviolet ray, the faster the curing speed. The general curing time is 10-60 seconds. For natural sunlight, the ultraviolet rays on sunny days will be stronger and the curing speed will be faster. But in the absence of strong sunlight, only artificial ultraviolet light sources can be used. There are many kinds of artificial ultraviolet light sources, and the power difference is also very huge. Low power can be as small as a few watts and high power can reach tens of thousands of watts.
The shadowless adhesive produced by different manufacturers or different models has different curing speed. The shadowless adhesive used for bonding can only be cured by light, so the shadowless adhesive used for bonding can only bond two transparent objects or one of them must be transparent, so that ultraviolet rays can penetrate and irradiate the adhesive.
operation instruction
1. One of the two objects to be bonded is transparent, and its surface is clean, dry and free of grease.
2. Apply UV shadowless glue on one side, close both sides, and illuminate with ultraviolet lamp or high-pressure mercury lamp with appropriate wavelength (generally 365 nm-400 nm) and energy to ensure that the light can really penetrate the bonding part.
3. It is suggested that the residual glue on the workpiece should be removed and re-illuminated when the initial positioning is carried out for about 6 seconds, until it is completely cured.
4. The curing time varies according to different preparation materials, adhesive layer thickness and ultraviolet intensity. Users are advised to buy an ultraviolet intensity tester and do a light intensity test before bonding to reduce the rejection rate.
5. The air temperature has a little influence on the activity of the adhesive, and the curing time should be appropriately extended when the air temperature is low.
6. During operation, do not forcibly squeeze the material to be bonded and rub it repeatedly. It is recommended to use a fixed tool.
7, plastic bonding, should consider the content of ultraviolet absorbent in plastic, too high content will seriously affect the ultraviolet transmittance, which also has a significant impact on the curing efficiency of glue, and even lead to the glue can not be cured.
8. Low viscosity products are recommended for large area bonding. If possible, it is best to buy vacuum equipment and stick it in a vacuum environment to remove bubbles and improve the yield.
Is there any way to break the glass?
There is no good way to stick to it. As the saying goes, second time around.
What can be stuck when the glass is broken?
You can go to the glass shop to buy special glass glue, or you can take the glass to the glass shop and let the master glue it for you.
