What are the differences between dyed film and metal film?

1 Answers

The differences between dyed film and metal film are as follows: 1. Touch: Dyed film uses ordinary polyester film as the base material. Due to its loose internal structure, it is easy to dye, has low strength, lacks elasticity and toughness, and has no texture. It is prone to wrinkling and fails to meet the basic safety and anti-theft requirements of automotive films. In contrast, metal film uses optical-grade polyester film, mostly in neutral colors, and feels thick, smooth, and dense in structure with high strength, thus offering high safety and excellent anti-theft performance. 2. Odor: Dyed film typically uses inferior adhesive containing large amounts of benzene and formaldehyde molecules, which volatilize under sunlight and produce a strong, pungent odor. Inferior films often use dyeing processes and contain many chemical pigments. Under sunlight, these pigments can chemically decompose, potentially releasing toxic chemicals that severely pollute the air inside the car and affect the health of drivers and passengers. Metal film uses PSA adhesive, which is not only colorless but also has a very faint odor, and its cost is several times higher than that of inferior films.

How to Fix a Black Screen in the Reversing Camera?

The phenomenon of a black screen in the reversing camera is most likely due to poor line contact. It is necessary to promptly check the wiring and the connection points of the vehicle's installation to see if there are any loose connections. Relevant explanations are as follows: 1. If there are loose connections, it will naturally lead to intermittent functionality of the reversing camera, or even a complete black screen. In this case, simply reconnect the loose parts properly. It could also be due to aging of the video power cable. Try replacing it with a new one. If the black screen issue is resolved, it confirms that the problem was indeed with the video power cable. 2. If after checking the above two scenarios the reversing camera still shows a black screen, it is likely due to prolonged use of the reversing camera, resulting in poor chip photosensitivity. This not only causes a lot of snowflake-like interference but also leads to a black screen. It could also be due to defects in the vehicle's circuit design.

Will a repainted new car qualify for triple compensation?

If you discover that a newly purchased car has been repainted and it has been verified, generally, minor repainting does not qualify for triple compensation. Triple compensation is only applicable in cases of severe accidents or particularly serious fraudulent behavior by the dealer. Methods to determine if a car is new include: 1. Check the manufacturing date: The vehicle's manufacturing date should match the date on the certificate of conformity, which is usually difficult to alter. If the manufacturing date exceeds 15 days, it is considered an old car. 2. Inspect the brake discs: Most modern small passenger vehicles use disc brakes (at least for the front brakes), making the brake discs a reliable indicator. Typically, after driving more than 200 kilometers, the brake pads will leave noticeable marks on the brake discs. There is usually a 1-2 mm gap between the brake pads and the outer edge of the brake discs. After a certain distance of driving, a noticeable "ledge" (very low in new cars) will form on the outer edge of the brake discs.

Does the car head sweeping the line in the S-curve during Subject 2 exam result in point deduction?

During the Subject 2 exam, sweeping the line with the car head in the S-curve does not result in point deduction, as long as the wheels do not press the line. Below are the relevant details about the S-curve exam: 1. Regulations: Original regulations: If any wheel presses the edge line, 20 points are deducted; crossing the line results in 100 points deducted. New regulations: If the wheels press the road edge line, it is a failure; stopping midway results in a failure; driving without shifting to second gear or above deducts 5 points. It can be seen that pressing the road edge line deducts 20 points and directly results in a failure. 2. Operation techniques: (1) Before entering the left curve, drive the vehicle close to the right side and keep the front corner of the car pressing the right line. (2) When preparing to switch to the right curve, straighten the direction and use the right front corner of the car to press the left line until the car safely exits the curve, then straighten the direction. (3) During the exam, pay attention to the new regulations; stopping midway is not allowed, otherwise the exam will be judged as a failure.

What is the reason for the rear air conditioning not blowing air in Wuling Hongguang S3?

The reason for the rear air conditioning not blowing air in Wuling Hongguang S3 is the damage to the rear air conditioning panel. Here are the relevant details: 1. Exterior: The I-shaped front grille gives the Hongguang S3 a spirited look, and the inclusion of LED daytime running lights reduces its 'utility vehicle' feel, making it appear less austere. The rear is designed to be more squared-off to maximize cargo capacity, which helps balance its dual purposes of passenger transport and cargo hauling. 2. Interior: The interior design of the Wuling Hongguang S3 is significantly better than that of typical microvans. It features a dual-tone brown and black color scheme, and the dashboard is equipped with a floating touchscreen, creating a sense of premium quality. Most importantly, Wuling has invested considerably in the materials used for the Hongguang S3, with soft leather wrapping on the dashboard and door panels, providing a comfortable tactile experience.

What Type of Engine Oil is Best for Toyota Vios?

It is recommended to use engine oil with a viscosity of 5W-30 for the Toyota Vios, with an approximate consumption of 4 liters. Currently, the mainstream engine oil brands include Mobil, Castrol, Shell, and Dusso Lubricants. Below are some methods to distinguish between good and bad engine oil: 1. Check the packaging appearance. Genuine oil has a one-time-use cap, with a sealing tin foil at the notch, which bears the manufacturer's special mark. If these features are absent, it might be counterfeit oil. To prevent counterfeiting, genuine oil has special marks on inconspicuous areas such as the label sticker, bottom of the can, inside of the can lid, and handle. If counterfeiters customize packaging for fake oil, a simple comparison between genuine and fake packaging can reveal the difference. 2. Observe the oil quality. Genuine oil is light in color, transparent, free of impurities, suspended particles, or sediment, and flows well when shaken. Counterfeit oil may be darker in color, contain impurities or sediment, have a strong or irritating odor, flow poorly when shaken, or exhibit a stringy texture when touched.

How to Deal with the Brake Light Staying On Constantly?

Brake lights are generally installed at the rear of the vehicle. The brake light staying on constantly may be due to a damaged bulb, a short circuit in the wiring, or a faulty brake switch. Damaged Bulb: Brake lights are used most frequently in a car, and the lifespan of the bulb is short. When the brake light does not turn on, the brake light bulb should generally be replaced. Short Circuit in Wiring: The tail lights of a car share a common ground wire. If the ground wire is broken or disconnected, the brake light will not illuminate, so do not forget to check the ground wire. Faulty Brake Switch: If the brake light switch is defective, all brake lights will not turn on. In this case, it is necessary to inspect the switch, and if it is damaged, the brake switch should be replaced. Brake lights are usually installed at the rear of the vehicle, with the main body color being red, serving to alert vehicles behind. Brake lights are categorized by material into gas brake lights and LED brake lights. Gas brake lights have mature technology, with the outer shell made of glass, while LED brake lights use LED materials, which are radiation-free, pollution-free, and have a long service life.
