Drivers who want to buy second-hand vehicles are worried that they will accidentally buy a soaking car. What is a soaking car? Why are people afraid of buying it? What is the risk of a bubble truck? This article talks to everyone about what a bubble truck is and what are its hazards.
Soaking water vehicles are cars that have been flooded. This time due to being flooded for too long, the equipment inside will usually be subject to a certain degree of damage, even if it is repaired and maintained, there are still many invisible disasters. Such vehicles are on the road and their safety index is often very low, with a high risk index.
Where are the dangers of opening a bubble truck? First, because vehicles are flooded, the vehicle's electronic equipment is usually inflexible, and electronic systems such as GPS satellite navigation are subject to interference. The metal parts of these electronic systems rust, resulting in poor circuit contact. This will interfere with the use of vehicle electronics.
Then the damage of the water tanker is the engine. When the engine is turned on after soaking, the sidebar will deform, the air in the system cannot be fully compressed, and the vehicle lacks the driving power. Or the phenomenon of air leakage in the piston ring, these are factors that interfere with the normal progress of the car.
Finally, due to the soaking of the soaking car for a long time, the bacteria inside there are many harmful substances, which usually interfere with the use of vehicle parts. For example, a four-wheel bearing will have an effect on this part. When the oil quality of the seal changes, there will be no lubrication. What are the consequences of this? The vehicle will have abnormal sounds and it will even break. All these have hindered the use of the car and there are still great hidden dangers.
There are all kinds of hidden dangers in swill trucks, and its harm should not be underestimated. Owners do not choose such vehicles for economic reasons. Not only are vehicles easily damaged, they are also extremely prone to accidents. When buying a vehicle, be sure to pay more attention to prevent the purchase of this type of water-repellent car.

The plasticization of automobiles is a major development trend of the international automobile manufacturing industry today. The current automotive market demand has shifted to lighter sports utility vehicles, minivans and other light vehicles, which will promote the development of lighter automotive materials. The light vehicle market has a very large demand for resins such as nylon, polypropylene, polyurethane and other engineering plastics, accounting for more than 30% of the total resin market demand; the demand for polyvinyl butyral accounts for about its total demand 85% of the total.
Plastic requirements
Excellent weather resistance, ensuring that it will not change color or aging and cracking after long-term use (including heat-resistant oxygen aging and light aging);
Good chemical resistance to resist the erosion of oil and daily chemicals;
Easy formability, sufficient fluidity for injection-grade materials, to ensure the formation of complex parts, and improve production efficiency;
Economical requires materials with high cost performance.
Material requirements for exterior parts
Weather resistance: weather-resistant materials should be used for parts that are not painted or electroplated, such as AES, ASA (AAS), PC/PBT (PET), etc.;
Heat resistance: Due to the low ambient temperature, the standard heat resistance level can meet the requirements;
Low temperature resistance: the material is required to have a certain low temperature resistance to prevent the components from cracking in the low temperature environment in winter;
Chemical resistance: to prevent the erosion of oil and acid rain;
Scratch resistance: The material is required to have a certain surface hardness and a low coefficient of friction to prevent scratches.
Material requirements for interior parts
Heat resistance: Due to long-term sunlight in summer, the temperature in the cabin is relatively high, and the interior materials are required to have high heat resistance;
Aging resistance: including thermal oxidative aging and light aging, to prevent aging, discoloration and deterioration of components;
Odor: For the health of drivers and passengers, materials should ensure low volatility and low odor;
Matte: To ensure driving safety, use matte materials or matte textures;
Scratch resistance: the material is required to have a certain surface hardness and a low coefficient of friction to prevent scratching and fluffing
