What is chassis armor? The scientific name of the chassis armor is the chassis anti-collision rust-proof sound-insulating coating, which is a high-tech adhesive rubber asphalt coating developed by 3M for the vehicle chassis.
The role of chassis armor:
Reducing driving noise, blocking road noise, providing vehicles with a good rubber coating to prevent the impact of flying stones and gravel to provide good protection, avoid moisture, acid rain, salt erosion of vehicle chassis metal, sealing the body gap
Chassis armor application area:
In the car floor wheel arc, fenders, fenders lining the hood inner panel car under the hood fuel tank bumper rear inner trunk other parts of the possibility of corrosion
Why is the chassis of our car rusty?
The gravel on the road is easy to be splashed by the speeding vehicle, constantly hitting the chassis and hub of the vehicle, etc. The antirust paint and galvanized layer on the chassis will be destroyed soon after leaving the factory, and the metal on the chassis will be exposed. outer. Muddy roads after rain and snow also attach sludge to the car chassis.
The snow on winter roads and the corrosion of industrial salt cleaners that are widely used in China, the erosion of rain on weekdays, and the moisture and salt in the atmosphere, especially in coastal cities, warm and humid climate coupled with salty sea breeze As well as the impact of possible acid rain in industrial cities, these factors can erode the metal exposed on the chassis, causing the vehicle chassis to rust, deform and generate noise. In addition, the sludge adhered to the chassis of the car will gradually penetrate the protective layer on the chassis, exacerbating erosion and shedding of the original zinc plating layer and protective layer on the chassis, and corroding the chassis. Lead to premature aging of the chassis.
What is the effect of chassis armor on the car chassis?
1, to ensure traffic safety - damaged chassis may cause some parts of the chassis deformation, in particular, the upper and lower swing arm, the right and left direction of the lever is easily deformed, some minor touches will also cause the oil sump or gearbox oil pan, etc. A slight leak occurred. These deformations and leaks are not easily detected, but they will seriously affect traffic safety. The data shows that many traffic accidents are caused by chassis deformation. In order to ensure traffic safety, the state requires that the chassis be inspected every year during the annual inspection of the vehicle. Any vehicle with chassis corrosion must be repaired before it can be re-routed.
2, to ensure the value of car - the better the vehicle maintenance, the higher the value of nature. After a period of driving, vehicles that have undergone chassis rust treatment (especially with a formal company's quality guarantee) will certainly be able to use higher value whether they are using or preparing to change cars.
3, to improve driving comfort - Because the chassis rust-proof using a flexible material for sealing treatment, on the one hand greatly increase the smoothness of the vehicle when driving, on the other hand greatly reduces the wind and defects in the process of driving, Therefore, the owner's comfort during driving is greatly improved.
The new car has been subjected to chassis rust treatment at the factory. Why use 3M chassis armor?
Various types of vehicles will be chassis rust-proof when they are shipped from the factory, but the rust-proof construction techniques and materials of different types of chassis are different. Imported high-end vehicles tend to use advanced technologies and materials, and the processes and materials used in ordinary vehicles are often relatively simple. Many cars only spray a thin layer of car paint, and even some models only spray a part of the car, domestic cars are Almost no spray. Under normal climate and geography conditions, the original rust-prevention measures can still play a limited role in protecting the chassis, but if there are any exceptions, it will not be sufficient. For example, the chassis of the Jetta that has been cutting prices has not been processed, and the Vikings have sprayed 10 cm wide on both sides of the bottom of the car. After cleaning, the entire bottom surface is gone. The road conditions in the country are often poor. The chassis of the vehicle will be subjected to more gravel tests than when it is abroad. In addition, the domestic climate and environment are often rather harsh. The content of acid and alkali in the air is high, and it will cause metal exposed by gravel and impact. Severe corrosion.
What are the varieties of chassis armor and what are their characteristics?
3M chassis armor includes four kinds of products: 8820, 8964, 8949, 8864, etc. 1. Modified asphalt and flexible rubber resin material 8820 has strong elasticity, which can prevent splashing and impact of sandstone and prevent metal surface from being damaged and rusting. , is the main coating of chassis rust.
2, SBR (polystyrene) rubber material 8964 passes the following tests:
500 hours 5% salt water immersion test --------- Anti-corrosion performance 500 hours, 23 degrees Celsius water immersion test ---------- Water resistance 90 psi impact test --- ------- Impact resistance (Note: 1 lb/in2 = 703 kg/m2 = 0.703 g/mm2)
Adhesion test with surface of iron plate and primer material ----------Adhesion performance surface and acrylic resin paint, polyurethane resin paint can be spray paint test -------- spray paint performance 3, SBS rubber 8949 has strong adhesive properties and overall performance, suitable as a transition layer, in some cases the surface can be sprayed (in the air from the dry one hour after the paint).
4, 8861 general-purpose rubber material passes the following tests:
2 weeks water immersion test (23 degrees Celsius) -------- water resistance 2 weeks high temperature test (82 degrees Celsius) -------- high temperature performance 40th grade grinding test ------- ---- Anti-abrasive performance (Note: 1 lb/in2 = 703 kg/m2 = 0.703 g/mm2)
What are the advantages of chassis armor?
1. First of all, there has been a major breakthrough in the selection of spray materials, and the use of flexible rubber has replaced the original material base structure with oil, paint, PVC, etc. as the main substrate.
2. Secondly, based on the different physical and chemical properties of various materials, a multi-component composite product has been developed to enable such products to have high tightness, waterproof and rust resistance, acid and alkali resistance, heat and cold resistance, and elastic wear resistance. Non-toxic environmental protection and other excellent features fundamentally overcome the shortcomings of traditional materials in terms of protection strength, stability and other aspects.
3. In addition, improvements have been made at the same time in terms of construction technology: the use of multi-layer spray coating of various component materials has enabled the distribution of components with different properties such as rust-proofing, waterproofing and elastic wear resistance. At the level of their respective responsibilities, the rationality and durability of the protective structure are improved.
4, more secure and more reliable.
