What glue is used for the mobile phone shell and what glue is best for gluing the back cover of the

It's impossible to tell what material your phone case is made of, but here's a list of them:

1）abs。Can be bonded with 502. The judgment method of the material is whether the surface of the plastic part is sprayed with paint, if so, even if it is not ABS, it can be bonded with 502.

There are many kinds of instantaneous adhesives, and the bonding characteristics of 502 are fast, but brittle, I wonder if you have other types of instantaneous adhesives? It is recommended to choose an instantaneous adhesive with strong bonding, such as 20m, which is both fast and strong.

In addition, the bonding method of 502 is also crucial, squeezing 502 onto a glass plate, dipping 502 with a thin iron wire, and applying adhesive to the non-cosmetic surface of the fresh fracture. 502 has a very strong wetting ability, and it will enter very fine crevices, about 3-4 times is enough dose, and more is not good. If you have already applied 502 to the fracture and it has not been successfully glued, it is advisable to remove the 502 coating if you bond it again, but I can't confirm whether the old coating will stick without removing it.

After bonding, it should be allowed to dry for several hours, more than 4 hours is recommended. Although 502 has an instantaneous bonding capability, it does not mean that the final strength is instantaneously reached.

Security issues. Glasses should be worn when using the 502. Avoid children, lest they learn from the example, 502 is an extremely dangerous thing for children.

If 502 does not enter the eyes, do not rub the eyes, rinse the eyes immediately with plenty of water and seek medical attention. (I've seen one myself).

2) ABS+PC plastic alloy. Tetrachloroethane (MC glue) can be used, but this glue is generally not available, and I don't know if there is one in the chemical reagent room. In addition, I think 502 bonding can also be used.

I don't think that AB glue can be bonded, because (1) this glue is probably difficult to apply to the adhesive surface; (2) The bonding area is thick; (3) The appearance may be unacceptable.

Acrylic structural adhesive for mobile phone shell bonding, or you can try epoxy adhesive (ISITIC-420), as long as the bonding strength meets the requirements, and try to use some glue with low halogen formula design.

It is better to mix the hardening glue with epoxy resin. At present, the most used and most mainstream are moisture curing reactive polyurethane hot melt adhesive and epoxy resin two-liquid mixed hardening glue, but moisture curing reactive polyurethane hot melt adhesive is mainly for products with a small bonding area such as connecting frames, and epoxy resin two-liquid mixed hardening glue is mainly for products with a large bonding area such as needle back covers.

The use of epoxy resin two-liquid mixed hardening glue is:

Mix the A and B of the glue in a ratio of 1 to 1 and stir well; Apply the mixture evenly over the back cover; Attach the back cover to the phone and press gently.

At present, the material of the back cover of the mobile phone is mainly glass and plastic, supplemented by ceramic, and niche varieties of leather and carbon fiber. As an emerging back cover material, ceramic has an excellent appearance and feel, but it has limited a large number of applications due to high cost, low yield, fragility and other problems.

The PC+PMMA composite plate prepared by co-extrusion technology has the characteristics of excellent appearance and hardness, and is the best solution to replace glass at present, and has been widely used as the back cover, but the current production capacity is limited, the product is easy to deform, the yield is low, the investment risk is large, and there is little room for process improvement and cost reduction.

The internal stress and deformation caused by the process of plastic sheet have a great impact on the bonding of the back cover, and if the internal stress is large and the deformation is large, there are higher requirements for the anti-warping performance of the tape.

It's okay to use a gum remover. It will not damage the appearance of the back cover. **Available online. It's the kind of glass bottle. But it's better to buy a little bit and you're good to go. This thing is very volatile.

Hello, dear! I'm glad to answer your questions, I'm Xiao Lin'er! I've seen your question and I'm sorting out the answer, please don't worry, if there are a lot of people, you need to wait a while! Thank you for your understanding!! 

Hello for you to inquire, the most used and most mainstream is the use of PUR hot melt adhesive and epoxy AB glue, PUR hot melt adhesive is mainly for the bonding area is slightly smaller, epoxy AB glue is mainly for the bonding area of the back cover of the needle, Ouyatu PUR hot melt adhesive ** business.

Glue is an intermediate connecting two materials, mostly appearing as an aqueous agent, belonging to the fine chemical category, with a wide variety, mainly classified by adhesive, physical form, hardening method and adherent material.

You can put some glue around the back cover of the phone in turn, but fix him a little

What is the size of your bonding area?

Dear, hello, I'm happy to serve you, there is a problem of how to get the viscose off the phone case, you can remove it in this way, you can choose 1You can use alcohol, spray it on the phone case, wait for the alcohol reaction to be completed, and wipe it with a towel2You can also use wind oil essence to apply it to the mobile phone shell, wait for the wind oil essence reaction to be completed, and then wipe it with a rag 3

Summary. Dear, I'm glad to answer for you: how to remove the adhesive from the phone case?

Answer: Use an eraser to wipe the place with glue on the phone case repeatedly, and then use soft toilet paper to wipe it 2 Pour a little white vinegar on the rag and wipe the phone case, which can effectively remove the residual glue 3 Use a hot towel to heat the area with glue, and you can also remove the residual glue. 1. Use a hair dryer to set a heat stop, heat the sticker position, then scrape off the post, and then clean it with alcohol.

2. Stick 502 glue on a small area, as long as you soak it in hot water, if a large area is stained with 502 glue, coated with acetone, and wait for about 5 10 minutes to remove. 3. Add 502 to the original place to melt the original 502, and then quickly wash it off with water. 4. With insulating oil, pour the insulating oil in the transformer on the table, and the 502 glue will quickly become soft and can be rubbed off quickly.

5. Use banana water to drop on the glue stains, and at the same time use an old toothbrush to continuously stir and brush, until the glue stains become soft and take off, then rinse with water, brush repeatedly, and brush until it is clean. 6.

Glue the plastic material of the back cover of the mobile phone with YH-818.

<> the adhesive on the phone case can be removed with nail polish remover, and the hair dryer can be turned on until the hot air is blown.

Then blow on the adhesive, wait for the adhesive to soften, apply nail remover to the adhesive, wait for about 5 minutes, and then wipe it clean with a rag.

The specific steps are as follows:

1. First power on the hair dryer, and then turn the hair dryer on to hot air.

2. Aim the hair dryer at the adhesive on the top of the phone case to blow the air.

3. After the adhesive is softened, apply nail polish remover to the adhesive.

4. After applying nail polish remover, wait for about 5 minutes, and finally wipe it clean with a rag.

The scheme is as follows:

1. Find a basin and put some hot water from the water heater in it.

2. Put the phone case in hot water, soak for 10 seconds, and take it out.

3. Put the phone case upside down on the table, it will be a little hot.

4. Use a brush or fingernail to slowly pick off the residue of the ring little by little, you need to be patient, and the force is not too great.

5. The effect may not be satisfactory at one time, and the steps need to be repeated many times until it is completely cleared.

6. Finally, dry the phone case, and it's done.

If it is soft silicone, soak it in water, and then scrape it with a dime coin, and the general dirt will be scraped off. If you encounter a stubborn point, it's okay to use a little force, because the edge of the coin is obtuse, so you are not afraid of scratching, but don't scratch it hard.

If it's hard plastic, it's soaked in water, just brush it with a small toothbrush.

There are other options:

1. Use soap and a little ammonia and turpentine to remove a lot of dirt and make the glass surface more shiny.

2. Use transparent adhesive with good viscosity to repeatedly stick and tear, and you can remove some of the surface.

3. Wipe it off with a little sodium water, or use paint thinner.

4. You can use a hair dryer to dry, and then gently scrape it.

5. Wipe with a cotton swab dipped in nail polish remover.

6. Wipe the wind oil essence.

7. Use a special detergent or sneaker detergent to wipe it.

8. Use the 4B eraser for drawing to be very soft, and you can erase it with the Korean eraser.

9. If the traces that have been left for a long time have hardened, you can use a hot towel to soften it before trying.
