How to identify the accident used car?
1, see the body frame. Whether a car has passed a major accident mainly depends on whether the body frame has a sense of inconsistency, and whether the front hood switch gap is abnormal and awkward. Look at the uniform fit of headlights, taillights, fog lamps, and bodywork sheet metal parts.
2. Observe the engine compartment. In the event of a collision, the first damage is generally a cover, such as a hood, bumper, fender, etc., but if the collision is very strong, it will spread to various structural components in the engine compartment due to the impact. Larger forces make it easier for the fixtures at various connection points in the engine compartment to be displaced. Whether it has been repaired or replaced, it can be judged simply by observing the paint near the fixing screws.
3, observe the car beam. This is very necessary. Because of serious accidents, Yuanbaoliang and the beam will be seriously damaged. Even if it is repaired, there will be traces of welding or painting. Even if it is replaced after replacement, Yuanbaoliang will be more susceptible to dirt. Pollution.
4, observe the appearance of the body. The painting of the vehicle must go through a scraping procedure. The car purchaser can gently tap the car body. If it is the part where the paint has been sprayed, the sound will be more boring. Generally, the sound of the parts that have not been painted is very crisp. If it is a damage to the top of the car, the passing car is a car that has passed over. It is also necessary to lift the vehicle lifter up and check the vehicle chassis for visible signs of injury or repairs. Check the vehicle steering system and suspension system.
5, tires, rims, rear axle also need to pay attention to observation, to see if there is a replacement, these can reflect whether the accident and the severity of the accident. If the shock absorber and the rear axle are particularly new and different from the old and new parts, this situation is more serious than changing the leaves only because it involves the suspension system, and the stability, comfort and controllability will be affected. .
6. Observe the glass number. The code on the glass hides a lot of information, such as the date of manufacture, such as origin. In the end, the glass was originally shipped from the factory, or it was repaired and installed after delivery. This information can also be known from the glass code.
PVB is a multi-functional Polyvinyl Butyral Resin by a chemical reaction and synthesis.
With high transparency, good toughness, flexibility, low temperature to fight resistance, and resistance to ultraviolet radiation, water, oil, anti-aging. PVB has very strong adhesiion to many kinds of materials such as: glass, metal, plastic, wood, leather and other materials, also has pigment dispersion and the excellent solubility of the resin.
PVB has been very widely used in the automotive and architecture safety glass interlayer , paint, ink, resistors, batteries, circuit boards, hot melt adhesive, the modified agent in the processing of textile fiber, etc.
