" The Mystery of Throwing Cards"
Today I will discuss some solutions, some solutions, some solutions, some solutions!
"What is PP+EPDM?" 》
Let's first take a look at its ingredients.
Basic formula: 30 parts of PP, 70 parts of oil-filled EPDM (naphthenic oil, etc.), appropriate amount of dipropylbenzene peroxide (DCP), appropriate amount of ultra-fine talc, and appropriate amounts of other additives.
Naphthenic oil? Does it contain oil? Of course, this is the main reason. Yes, PP+EPDM sometimes produces oil when exposed to heat. It feels oily and slippery to the touch. In fact, many vehicles have already used this material to make parts. This is because It has the advantages of high elasticity, no roll stickiness, fatigue resistance, abrasion resistance and media resistance, high tear strength and excellent ozone resistance and weather resistance, and it can be degraded.
PP+EPDM rubber is an inert surface material. Direct use of double-sided adhesive tape will encounter the problems mentioned above; therefore, it must undergo special treatment to achieve a high-strength bonding effect.
<<So what do you think? >>
The PP+EPDM material system will be more difficult to bond and requires surface treatment and the selection of special adhesives.
It is necessary to use solvents and degreasers to destroy the surface of the material and remove plasticizer or surface stains to increase the adhesion performance.
Press firmly for 10 seconds to remove the air between the double-sided tape and ensure contact with each other.
<<In fact, many agents have tried to avoid the license plate crisis? >>
Because the Japanese car dealer's own structural design of the car is to install the Japanese license plate on the left side, and the Japanese license plate is made of wire, this is not the subject of this discussion.
When it comes to European cars, I have been a dealer for more than ten years and have witnessed many accidents involving agents dumping license plates. Let me talk about a few representative ones:
Audi - The tail plate, please explain, because it is a design problem. The position of mounting the plate, it has two wire caps protruding 4mm on the left. If you don’t increase the height of the tape, it will definitely fall, but I taught you back then. If you use an agent to handle it, you won't have this problem at all. As for the home, the top brand seems to have no shelf, some parts have different models, and the home agent uses gongs and wires to solve the problem. In fact, it can be pasted, but it will take some time.
Mazda - a pull-top brand. Some of the cars supplied to Hong Kong are European versions. Their head-mounted frame is made of PP+EPDM. And the dealer in Hong Kong added two pull-tops to allow for threading.
Benz - In the past, there were many cars with very sharp heads, A, E, etc. They could be removed with all-purpose glue and five-element double-sided tape. Then the agent turned left and found that this car only has two outer frames. The intake is very stable, but it is too big. Old and strange Zuo Bu Shao.
Alfa - The heads are extremely curved. The agent used a hot air gun to bend each one before installing it, but the heads were all exposed to the sun and were damaged by the high temperature. They were all fixed with wires afterwards.
Porsche - They are all made of PP+EPDM, but the agent knew about this problem early on, so they specially added a left piece of cast iron (in some cases, they changed it to a left aluminum alloy piece), used a gong wire to hang a license plate frame on it, and then affixed the license plate, but the system just It was not easy to see if it was left one level higher than the body, causing the Macan's head sensor to squeak. I had to go back to Paris to dismantle a piece of aluminum, surface-treat it, and install it directly on the license plate holder.
BMW - The first brand of rubber you see is Luosi, which evolved from the previous ones.
VW - This is great. The former agent used enough adhesive tape to install the license plate directly on the painted surface. The disadvantage is that it is very difficult to remove the stains. If we don’t use our traceless adhesive tape, it will really kill me. Next move.
Land Rover - The agent is very violent and can use sandpaper to save the surface of the left card holder and paste it first, and it works!
A certain T brand - PP+EPDM, PP+EPDM, PP+EPDM, I have said it three times, this is a problem, it 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. Having too many cars will increase the number of license plates and cause more dissatisfaction! !
Summary: I really appreciate the agents who have made improvements above. I will give them the License Plate Progress Award with some applause. In fact, if the installation is proper and the system is really looking for the root cause, the problem can be solved. If you don't examine yourself all the time, whether it's your problem or not, and it's just a problem of knowing how to talk to others, the problem will never be solved.
