According to the August 15th report of the Japanese Response Automotive Professional Website, everyone should have seen the words “Car Coating†in the 4S shop or gas station. Coating can help the car withstand the erosion of wind and rain, prolong its service life, and facilitate the passing of annual examinations, and thus it is very popular in recent years. From the waxing era to the coating age In the past, when it comes to car maintenance, people first thought about waxing. Waxes are mainly vegetable oils. They have high water solubility and have the advantages of smoothing scratches and brightening the car. However, it is easy to get dirty and it is not resistant to high temperatures and rain. Car wash, sunshine and hot engine can cause wax to fall off on its own. With the passage of time, more advanced coatings have replaced waxing. Coating refers to coating a film on the surface of a car body with a resin or the like. The advancement of the coating is not to make the car sparkle, but to protect the car from being scratched and soiled. Nowadays, the maintenance that gives the car a short-lived shine and waterproof effect is called waxing, and the maintenance of a durable luster by a professional lotion is called a coating. Various situations of body injuries Bird droppings When acidic bird droppings fall on the coating, even if you do coating, the coating film will be saturated, acidified and corroded. 2. Rainwater When the moisture dripping on the body evaporates, the dirt in the rain or the bleach in the tap water will remain on the coating, forming a white circle stain. 3. Water droplets Drops of water that land on the vehicle body gather sunlight like a magnifying glass, causing damage to the painting. Type of coating There are many kinds of films, which can be roughly divided into grease films, resin films, and glass films. Lipid film The grease film refers to a film that is coated with oil to achieve a waterproof effect. Waxing is a grease film. This takes advantage of the oil's insoluble nature and is easy to maintain. However, its disadvantage is that it is easily washed away by rain, and its maintenance time is short. Resin film The resin film is a polymer compound coated with ion molecules that adheres to the body. That is, the silicon polymer, the fluorine polymer, and part of the glass film belong to the resin film. The advantages are cheap and simple construction. The disadvantage is that it is not easy to last. Glass film Glass-like film refers to the glass-cellulose mixed with other components for body coating. The difference between it and the crystal glass coating is that it incorporates other ingredients that are not as good as the crystal glass coating in all aspects. However, durability is better than grease film and resin film. Crystal glass coating Crystal glass coating is now the best coating, it uses the unique transparency of the glass to protect the body. The glass coating has the advantages of long duration, less adhesion of water droplets and dirt. However, it is difficult for non-professionals to plate the glass film, so the construction cost is expensive. About going to water The method for removing water from a vehicle body can be divided into two types, a water-proof type and a water-soluble type, from the point of view of the contact with the water droplets. waterproof type The waterproof type is characterized by decomposing water into small water droplets. Such materials contain a large amount of grease, which can erode the coating when the oil molecules are deteriorated, and also cause water drop problems. Water soluble This type of material removes dirt from the car body surface with a large amount of water. The disadvantage is that it is difficult to notice the coating effect. Now, do you have a certain understanding of the coating? Many businesses say coating, washing can be washed. However, some stains are not washable, so routine maintenance is still important. The type of coating is not good or bad. It is important to fully understand the characteristics of each film and choose the film that is suitable for the car. Recently, there is an increasing demand for advanced membranes in 4S stores. You can give your own car coating, you can also go to the 4S shop to enjoy a senior coating, I believe you must be greatly amazed at the advanced coating to bring brightening, brightening effect.
The basic Aluminium Die Casting process consists of injecting molten metal under high pressure into a steel mold called a die.
