" The Mystery of Card Swinging"
Let me discuss the next point today!
"What is PP+EPDM?" "
Let's first look at what it is.
Basic formula: 30 parts of PP, 70 parts of oil-extended EPDM (naphthenic oil, etc.), appropriate amount of dipropylbenzene peroxide (DCP), appropriate amount of superfine talcum powder, and appropriate amount of other additives.
Naphthenic oil? So there is oil in the rice system? Of course, the main reason for this is that PP+EPDM sometimes leaks out of the oil rack when it is heated. It feels oily and slippery to the touch. In fact, many vehicles have already used this material to make parts. The system has advantages, high elasticity, no sticky roll, fatigue resistance, wear resistance and medium resistance, high tear strength, excellent ozone resistance and weather resistance, and can be degraded.
PP+EPDM rubber is an inert surface material. If you use double-sided adhesive tape directly, you will encounter the above-mentioned problems; therefore, it must be specially treated to achieve high-strength bonding.
<<What do you think? >>
The PP+EPDM material system is more difficult to bond, and requires surface treatment and selection of special adhesives.
It is necessary to use solvents and degreasers to destroy the surface of the material, remove plasticizers or surface stains, so as to increase the bonding performance.
Press firmly for 10 seconds to remove the air between the double-sided tapes and make sure they touch each other.
<<In fact, many agents have tried to dump the license plate crisis? >>
The Japanese car dealership has a Japanese license plate on the left side because of the structural design of the car itself, and the Japanese license plate uses gongs, so I don’t want to discuss it here.
European cars, I have been in the left for many years and have witnessed many accidents of dealers and dealers. Let me tell you a few representative ones:
Audi - Drift card, let me explain, because it is another design problem, the position of the card, it has two wire caps protruding left 4mm, if you increase the height, the sticker will definitely fall, but I taught at that time The agent handles it, and now there is no such problem at home. Now, the top card seems to be unreliable, and some parts have a lot of models, and the agent solves it with wires. In fact, it can be posted, but it takes some work.
Mazda - head-shaking brand, some of the cars supplied to Hong Kong are European versions, and its head-mounted frame is PP+EPDM, and the family is good, the Hong Kong agent adds two pull caps, which can be used for silk.
Benz - A lot of cars were very sharp before, A and E, and I used sunscreen and five-line double-sided tape to throw them away. After that, the agent turned left and came home. There are only outer frames on both sides. The intake is very stable, but it is too big Old and blame the left.
Alfa - The head is really extremely curved. The agent used a hot air gun to blow and bend each head before installing it, but the hair was only spent in the sun. It was exposed to high temperature, and then it was fixed with gongs.
Porsche - They are all PP+EPDM, but the agent knew about this problem early on, and specially added a piece of pig iron (the left aluminum alloy sheet was changed to the left), and used a wire to fix a license plate and then pasted the license plate. It will be one step higher and left the car body, which will cause the head sensor of the Macan to ring. It is necessary to go back to Li to dismantle the aluminum sheet, after surface treatment, and directly install it on the license plate frame.
BMW - Everyone sees that the top brand has granules, which are gongs, and they are all evolved from the past.
VW - It’s so cool, the former agent used full-foot adhesive stickers, and the car’s design is to install the license plate. The individual digits are directly pasted on the painted surface. The disadvantage is that it is very difficult to remove the stains. If you don’t use my non-marking adhesive stickers, you will die. next hand.
Land Rover - As a proxy, the master is so violent that he will use sandpaper to save the surface of the left card holder first, and it will work!
A certain brand - PP+EPDM, PP+EPDM, PP+EPDM, I have said it three times, it is a problem, must be wiped with solvent before installing the brand, and then press hard to install! ! Having too many cars and not having time is no excuse. Too many cars will cause more dissatisfaction with the number of license plates dumped! !
Summary: I really appreciate the above agents who have improved, and I will applaud and award the License Plate Improvement Award. In fact, if you install it properly, you will really get to the bottom of it, and you can solve problems. If you don’t check yourself all the time, it’s not your own problem, it’s just a matter of understanding words and people, and it will never solve the problem.
