When the doors are disassembled and the interior panels are empty, can I remove styrofoam?

People who say cars know about styrofoam inside.

There shouldn't be many, but I'll barely count one. In the past, my family was in the building materials business, and I had to deal with styrofoam. He has also visited the manufacturer many times for technical training.

It's no exaggeration to say that if you want, I can fill you a bottle right now. Based on what I've learned about styrofoam, I don't think it's a good fit for use in cars.

What is styrofoam.

The full name of styrofoam is "polyurethane foam caulk", and the two materials are mixed and pressurized in a tin can, which is about the same size as the previous insecticide bottle. When using, press the switch, the mixed material is sprayed out under pressure, and after encountering air, it foams and expands, which can be filled in some parts, and can also be used as temporary bonding or molding.

The above pictures are examples of styrofoam used for caulking, sealing and modeling.

Because the expansion degree of styrofoam is very large, it can usually expand to dozens of times or even more than the original, and the structure of the expanded foam is similar to that of the sponge after curing, which can play a certain role in sealing and isolation, so it is often used for door and window installation in engineering, filling the gap between the door frame, the window frame and the wall, and it is very convenient to use.

But it's not a good idea to use in a car, mainly for several reasons:

1. Difficult to clean.

It is no exaggeration to say that nine out of ten salesmen of styrofoam manufacturers have some traces of styrofoam residue on their clothes or shoes. Because the salesman often has to give samples to customers, and the styrofoam is very sticky when it is just punched, and the clothes or shoes cannot be removed as long as they are stained. If a car interior or paint is stained with styrofoam, it is difficult to clean it completely even if you clean it immediately.

2. The degree of expansion is not easy to grasp.

The picture above shows the styrofoam applied during the installation of the window frame. You can see that a lot of it has swelled out, and this is because the styrofoam will continue to expand for a period of time after it is finished. Workers need to use a blade to cut off the excess.

Although there are now new products known as pre-foaming, that is, foaming in place immediately after punching, it will continue to expand more or less in the later stage. If you are unaware of this feature and use it to fill the door, it is estimated that the styrofoam may deform the top of your door trim panel.

3. Flame retardant.

Ordinary styrofoam ignites at one point, and the fire is still very large, but due to engineering needs, there are now flame retardant styrofoams. However, there are not many that can effectively flame retardant in line with the national standard, and some projects often buy unqualified products with flame retardant properties for large-scale purchase orders, not to mention that we personally go to buy it.

4. Aging resistance.

In the end, there will be a closed link in the use of styrofoam, that is, the use of sealant.

or other materials that enclose the styrofoam inside. Because the styrofoam only plays the role of volume filling, or a bit of low-cost to cover the ugliness, if the styrofoam is exposed to the air, then it will inevitably age within a few months under the moisture of the sun and rain, and it will be broken by hand.

Therefore, styrofoam is not very suitable for use in cars. Unless you have a grudge against the owner.

The car interior panel is empty, which is very normal, and the styrofoam can be beaten, but the styrofoam may cause abnormal noise of the vehicle or the body vibration is relatively large, and it is generally not recommended to beat the styrofoam.

In such a situation, you can use styrofoam, because after playing styrofoam, it is likely to make the sound insulation effect of the car better.

When the door is dismantled and the interior panel is opened, it is found that the inside is empty, in which case it is not allowed to be openedStyrofoamTarget.

In life, some drivers will find that the interior panel inside the door is empty in the process of repairing the vehicle. Therefore, in this case, the driver will want to make the door better insulated by filling it. So as to reduce the presence of noise in the process of driving.

1. Do not beat styrofoam.

If you open the interior panel of the door and find that it is empty, you cannot use the styrofoam. Because the smell of styrofoam will be relatively large, and even some pungent odors will appear. The main thing is that this flavor generally does not volatilize for a long time.

Therefore, after injecting styrofoam into the door, the driver and occupants will not have a better riding experience in the process of riding the vehicle. <>

Second, not all doors are empty.

In fact, some drivers will find that the inside of the door of their vehicle is empty, but this phenomenon does not mean that this is the case for all vehicles. Because for some vehicles, there may be certain differences in configuration. Therefore, when the interior panel is removed, the door will have a suitable padding inside.

And these fillers are not only more green and environmentally friendly, but also relatively good sound insulation. <>

3. My personal opinion.

I think for all the vehicles, the original configuration is the best. Because the design and function of the car before leaving the factory are relatively reasonable. Therefore, I think that after the driver buys the vehicle, he generally does not need to rectify the vehicle.

Because in the process of private rectification, it may meet the needs of the driver at the same time, so that other functions of the car will be affected to a certain extent. Therefore, I personally feel that the driver should adhere to the configuration and quality of the original vehicle. Only in this way will you have a more comfortable experience during driving.

It is not possible to beat the styrofoam, because the styrofoam Chinese style still has a certain impact on health, the overall smell is relatively large, and can not be completely dissipated, so it will affect the health of personnel in the long run.

No. Such glue will have a strong odor and may affect the health of personnel if used for a long time.

When most car doors are opened, the back of the interior panel is empty, but the foam rubber cannot be used. There are also substances in the foam rubber that affect the health of the Chinese style, and the overall smell is large and cannot be completely dissipated, so it will affect people's health for a long time. The back of the door trim panel is usually empty, no problem.

The use of soundproofing materials does not affect the soundproofing of the car. If you want to improve the sound insulation quality of your car, you can use other methods. If you are not satisfied with the sound insulation of your car, you can thicken the sound insulation cotton in the interior panel to improve the overall sound insulation effect.

Engine insulation cotton can also be added to the engine room, which can improve the texture of sound insulation in the chassis and other places while reducing the engine sound. Officially known as "polyurethane foam filler", the foam rubber is mixed with two materials and pressurized to fill into a tin can, the same size as the previous pesticide bottle. When in use, press the switch, the mixed material is sprayed out under pressure, and when it foams and expands in the air, it can fill part of the part and be used as pre-bonding or modeling.

The expansion of foam rubber is very large, usually more than ten times of expansion, the expanded foam body is similar to the sponge structure after curing, and plays a certain sealing and isolation role, and is often used in the installation of doors and windows in the project, filling the gaps between the door frame, window frame and wall, and it is very convenient to use I think that for all vehicles, the factory layout is the best. Because the car is designed and functionally reasonable before it leaves the factory. Therefore, I think that after the driver buys the vehicle, there is generally no need to rectify the vehicle.

Because in the process of unauthorized modification, while meeting the needs of the driver, it may have a certain impact on other functions of the car. Therefore, I personally believe that drivers should protect the configuration and quality of factory vehicles. In this way, in the process of driving, you will have a more comfortable experience, in fact, it varies from person to person, after all, we all know that styrofoam Chinese style also has a certain impact on health substances, the overall smell is relatively large, and can not be completely dissipated, so it will affect the health of personnel in the long run.

After most doors are removed, the back of the interior panel is empty and the foam glue cannot be removed, because the Chinese foam glue also contains certain substances that affect health. The overall smell is large and cannot be completely dissipated, which will affect people's health for a long time. The use of soundproofing materials such as soundproofing cotton will not affect the soundproofing effect of the car.

If you are not satisfied with the sound insulation of your car, you can thicken the sound insulation cotton on the interior panel to improve the overall sound insulation effect. Engine soundproofing cotton is added to the engine compartment to reduce the sound of the engine. It can also be used to improve the sound insulation texture of the chassis and other parts.

Although Styrofoam has sound insulation, it is in poor health. The car is very well sealed and the doors are very airtight.

Acoustic noise cancellation can also be used, which is also a type of active noise cancellation. Many high-end luxury sedans have active noise cancellation, especially during highway driving, strong tire noise and engine noise can affect the overall driving experience, and noise can be reduced through noise reduction. In the industrial sector, products that need to be filled and sealed have protective and adhesive properties.

Styrofoam can accomplish these tasks and get the most out of its performance. The foam material expands from the jar and comes into contact with air. When it encounters moisture, it solidifies and forms a foam.

After curing, it can play the role of filling, bonding and sealing, and polystyrene foam can also play a role in heat insulation and sound absorption, which is very suitable for some special fields. The principle of Styrofoam is very simple. Once it is easy to use, it can take full advantage of its superior performance.

The product has good environmental protection and energy-saving performance, and it is worth using. In order to exert its powerful functions, we should choose trustworthy brand merchants. Provide integrated adhesive application solutions.

It can be used in new energy, military industry, medical treatment, aviation, shipbuilding, electronics, automobiles, instruments, power supply, high-speed railway and other industries.

Yes, at this time, foam glue can be used, which can block the gaps and can also play a role in reinforcement.

This should not be done, as this will lead to very poor air quality and will seriously affect your health.

No, because this behavior does not achieve sound insulation and has a negative effect on the body, so it is wrong.

If it's for sound insulation, it's okay, but I personally recommend not hitting it, because that thing is useless, but if the sound insulation of the car is really poor, it's okay to try it.

It is not allowed to blow styrofoam, because styrofoam has the property of expansion, and it is difficult to clean after drying, and it may support these corners until deformed due to thermal expansion and cold contraction, so it is not allowed.

No. If you use styrofoam by yourself, it will affect the performance of the door, so it is not recommended to use styrofoam.

The inside of the car interior panel can not be styrofoam, because although the styrofoam can play some role in sound insulation, it will affect the heat dissipation of the car, and there are certain safety hazards in daily driving.

Styrofoam can be beaten. However, I recommend that this operation be carried out by a professional car repair shop. Otherwise, if you damage your car, you will lose more than you gain.

No. Because after the styrofoam is applied, the safety of the car door is not guaranteed. Therefore, styrofoam should not be beaten.
