What to do if the all purpose adhesive sticks to the paint on the surface of the door

1. Wipe it with a paper towel dipped in some alcohol (it is best to use industrial alcohol, or make do with medical treatment), and then rub it a few times to be clean.

2. Use acetone. Same method as above. The amount is small and thorough, and the best thing is that it removes these residual gums very quickly and easily, which is better than sprinkling sperm.

Both of these are solvents and are the most effective of all methods.

3. Use nail polish remover. The usage is the same as alcohol acetone. The effect is also very good. Nail polish remover does not require quality, good or average, as long as it can wash off the nail polish.

4. Use hand cream. Tear off the printed product on the surface first, then squeeze some hand cream on it, and slowly rub it with your thumb, and rub it for a while to rub off all the sticky residues. Just slow down.

Hand cream is an oily substance, and its properties are incompatible with glue. This is the use of this property for glue removal.

These Articles 3 and 4 are introduced in a column of **TV 1. The material is easy to find and convenient, and it can remove residual glue.

5. Use banana water. It is an industrial agent used to remove paint, and it is also easy to buy (where paint is sold). The method is the same as alcohol acetone.

Hello! Rub it slowly with water [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The treatment method of gluing to the car paint is: 1. Wet the adhesive on the car paint with a hot towel; 2. Open the cleaning agent or adhesive remover and spray it onto the adhesive part; 3. Let stand for one minute; 4. Carefully wipe the glue on the paint with a sponge cloth until the adhesive is cleaned. Precautions for gluing to the car paint are aged:

1. It is necessary to clean up the glue on the paint in time after it is found; 2. After cleaning the body with detergent, rinse the detergent in time; 3. Do not use brute force to clean up or rashly use carburetor, gasoline, banana water substances to clean. Gluing to the pure car paint will affect the appearance of the vehicle, causing the paint to be corroded and fall off.

It can be scrubbed with a soft brush or rag dipped in turpentine or benzene, then brushed with soap, and finally wiped with water. If you can't wash it down, you can use a mixture of 1:1 turpentine and ether, wipe it with the mixture for 10 minutes, and then wipe it with gasoline to wash it clean.

How to dirt on the general smooth surface (application glass, aluminum alloy):

1. Use soap and a little ammonia and turpentine to mix liquid, you can remove a lot of dirt 2, use viscous transparent glue to repeatedly stick and tear, you can remove some of the surface 3, wipe it off with a little dilute sodium water, or use paint thinner 4, you can use a hair dryer to dry, and then gently scrape it 5, wipe it 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 wiping it.

Since 502 glue is a kind of resin glue, you can use acetone or banana water to drop on the glue stains, and you should use a brush to continuously brush them repeatedly, and then rinse them with water after the glue stains become soft and take off.

It can be wiped with a small amount of gasoline.

The main types of adhesives commonly used in structural applications in automobile manufacturing are as follows.

1) Structural adhesive The so-called automotive structural adhesive refers to the high bonding strength, which can withstand the force as a structural part, and its bonding strength, for ordinary steel plates, the shear strength can be 20MPa, and the peeling strength is above. This kind of glue is usually modified epoxy resin glue, such as FAW has used CJ-1 structural adhesive to bond the engine hood and the front and rear reinforcing beams, so as to glue instead of welding, reduce solder joints, solve the problem of pits in the solder joints on the surface of the middle cover, and improve the appearance quality of the car.

2) The so-called folding structure of the folding glue is to combine the inner and outer plates with bonding and folding methods, this structure, without spot welding, eliminates the spot welding pits, keeps the body smooth and beautiful, and also improves the anti-corrosion and anti-rust ability. Most of the hemming adhesives need to be heated and cured, and the adhesive strength is high.

3) Expansion damping glue Before the body is welded, the viscous paste damping glue is coated (paved) on the reinforcing beam or inner plate, and then combined welding. The shock-absorbing adhesive does not need to be set up with a separate heating and curing equipment, and it is usually possible to use the electrophoretic primer drying oven to heat cure. It not only increases the rigidity of the top cover, but also plays a role in shock absorption.

For example, the FAW CA6440 van door inner and outer panels and side walls are all made of CB-1 shock-absorbing film to solve the noise problem.

4) Spot welding glue automobile body is generally welded by steel plate, so the existence of baking joints is inevitable. The application of spot welding adhesive ensures the sealing quality, which is characterized by stable conductivity, good adhesion before curing, no contamination of phosphating solution and electrophoresis solution, and no organosilicon substances.

5) Anti-stone chip coating In the fast driving of the car, the bottom plate, wheel cover, skirt, etc. will be affected by the sand and gravel brought by the wheel, resulting in the coating peeling off, the steel plate rust to resist this impact and shock absorption, and the bottom of the large body should be coated with a layer of glue. Hit damping coatings. Now it is used as a material for anti-stone chip and thermal insulation damping coatings for automobiles.

6) Anti-vibration and heat insulation damping film The damping and heat insulation film laid on the bottom plate of the car and the bottom plate of the truck cab, the front wall and the wheel cover are also based on asphalt, with rubber powder and inorganic filler, which are spread on the bottom plate after the primer is dried by hot melt, self-adhesive or magnetic, and softened by heat when the middle coat or top coat is dried, and closely fit with the covered parts, which plays the role of vibration absorption, heat insulation and preventing noise transmission.

Glue is bonded between plastics.
