Car makeover and make four changes in car body paint surface maintenance

1. Seal "glaze"

Why does the editor want to put quotation marks on the word "glaze" of "sealing glaze"? Actually, glazing is just a way of saying that there is a way to protect the lacquer surface, and "glaze" actually refers to the process of firing ceramics. At a high temperature of nearly 2000 degrees, this kind of protective film with a glamorous appearance and strong texture will be formed, but in the process of sealing the glaze, all the maintenance experts can't achieve this effect with their best efforts.

In fact, car glazing is just a concept of publicity and hype. Because waxing has many functions and effects, some smart paint maintenance companies have developed the concept of "sealing glaze". Daily waxing may only cost one hundred and eighty dollars. The price of the sealing glaze is often around 1,000 yuan, and the main difference between the two is the length of the effective time.

In fact, the glazing master in the maintenance shop does not know what the "glaze" is. I don't believe it. The next time I go to the shop, a car owner who loves can entertain the glazing master.

The principle of sealing glaze is not complicated: the sealing glaze is a polymer glaze that is shocked into the pores of the paint surface by the physical action of the machine to form a strong mesh protective layer, which is closely attached to the paint surface, just like Wear invisible protective clothing to the car, so as to achieve the purpose of protecting the paint.

The function of the sealing glaze is better understood: in the daily use of the car, it is easy to attach dirt, and the car that has just been washed will be grayed out again soon after the car is washed out. , Especially in cities with poor air or areas with poor environmental cleanliness. The glaze has the characteristics of non-stickiness and no adhesion of impurities, so that the paint surface can be kept clean for a long time even in harsh and polluted environments, and it can effectively resist the influence of temperature on the car paint, and the hardness of the paint surface is also It has been comprehensively upgraded and has the functions of anti-acid, anti-alkali, anti-fading, anti-oxidation, anti-static, high fidelity and so on. After the new car is bought, the glaze is removed, which can keep the car paint bright and glorious. The old car can be used to seal the glaze to restore the oxidation and fading of the car paint, which has a refurbishing effect. Most of the prototypes at the auto show have been glazed, so they look crystal clear and radiant.

And the sealing glaze is suitable for any car paint, so that the old paint has a facelift effect

Speaking of the frequency of car glazing, there is a direct relationship between the use rate of the car, the air environment, and the number of car washes. Normal car seals are finished and maintained for a second time in about a year. In terms of the weather in Hangzhou, the sealing interval is about 3 to 4 months.

Second, waxing

Waxing is the most basic means of car paint surface maintenance. The concept of wax has evolved from simple waxing and glazing to today's protective glazing. It has become a necessity for contemporary car beauty care. Two issues should be noted before waxing: one is wax selection and the other is operation.

The wax selection should be carried out according to the needs of car paint protection. Try to choose carefully according to the different effects of car wax combined with the characteristics of car paint, so that the effect will be more obvious. The waxing operation is generally carried out after the car body is washed. The current car wax is mostly liquid wax. Before use, shake the product evenly, wipe it with a small amount of wet cloth or sponge on the surface of the car paint, and after a little dry, Then dry it repeatedly with a soft cleaning cloth; there are also some solid waxes, the operation method is basically the same, the more advanced wax is more time-saving and labor-saving when opening the wax. The waxing operation should be in a cool place. In addition, after grinding and polishing, a car must be coated with protective glazing wax, which can double the gloss of the car paint. And has a long-term protection.

The choice of car wax is also very definite. Many driver owners have a one-sided understanding of waxing, either frequent waxing or simply do not beat; some drivers believe that the more expensive the wax, the better, specially selected imported car wax . In fact, these practices are inappropriate.

So, how to wax the car? First of all, there is a lot of choice in the choice of car wax. At present, there are many types of car wax on the market, ranging from solid to liquid, high-end and mid-range, and domestically produced. And import options. Because the performance of various car waxes is different and their effects are different, you must be careful when choosing them. Improper selection can not only protect the car body, but also change the color of the car paint. Under normal circumstances, comprehensive consideration should be given to factors such as the role of car wax, the age of the car, the color of the car paint, and the driving environment. For high-end cars, high-end car wax can be used; for new cars, it is best to use color wax to protect the luster and color of the car body; it is appropriate to use anti-UV car wax in summer; when the driving environment is poor, it is more appropriate to use resin wax with outstanding protection ; For ordinary vehicles, use ordinary pearl or metallic paint series car wax. Of course, when choosing the car wax, you must also consider the color of the car paint. Generally, the dark car paint uses black, red, and green series of car wax, and the light car paint uses silver, white, and pearl series car wax.

3. Coating

The definition of automobile coating is analyzed from a professional perspective. In order to be different from the sealing glaze, the real automobile coating should be inorganic coating, that is, crystal glass coating that will never oxidize. Only inorganic coating is the coating layer that covers the surface of the car, and will not be oxidized and disappeared by external factors such as ultraviolet rays and acid rain. Under normal use of the vehicle, the paint is protected for a single time for about 1 year, so it can be called a car coating. .

The coating has 9 major functions:

A car coating can prevent oxidation and aging of paint surface,

B can greatly improve the clarity of the varnish on the surface of the car paint. It is that the car paint has just been glorified.

C corrosion resistance. The hard non-organic (glass crystal) film layer itself will not oxidize, while also preventing external acid rain, flying insects, bird droppings, etc. from corroding the car paint. The dense glass crystal film has super corrosion resistance

D high temperature resistance. The glass crystal itself has the characteristics of high temperature resistance, which can effectively reflect the sunlight and effectively reflect the external heat radiation to prevent the high temperature from damaging the car paint.

E Anti-scratch. The hard non-organic (glass crystal) film layer can increase the hardness of the car body surface to 7H, which is much higher than the hardness of the car wax or glaze 2H-4H, which can better protect the car paint from the damage of sand.

F is easy to clean. The ion-ion coating has super self-cleaning property and water repellency, and it is not easy to adhere to dust and dirt. When cleaning, only clean water can be used to achieve the cleaning effect.

G ultra-long lasting and strong toughness and extensibility, usually protect the surface brightness of the car paint, forming a mirror effect for more than 2 years, far exceeding waxing and sealing.

H-Ultra-Environmental uses water-contained and environmentally friendly materials. It does not oxidize itself and will not cause secondary pollution to car paint. Traditional waxing and glazing projects will easily cause secondary pollution to car paint.

I super water repellent. The surface of the hard non-organic (glass crystal) film layer after fluorine treatment has super water repellency, so that when the water falls on the car body, it shrinks into water droplets and effectively prevents the formation of scale.

Summary: If waxing is the first-generation car paint care product, then the sealing glaze can be said to be the second generation, and the car paint coating is the third-generation paint care technology, that is, the car paint surface is coated with a layer of hardness High, flexible and anti-oxidation protective film. The reporter heard another voice in a beauty shop, "In fact, my sealing glaze is a kind of ytterbium plating. In the same way, a layer of paint is applied on the surface of the car paint." Auto beauty technician introduced, although in these names There is a distinction, but the principle is still the same, only the materials used and the effects achieved are different.

Alternative means: electroplating

Electroplating (English name: Electroplating), the principle is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis, which is to use electrolysis to attach a layer of metal film to the surface of metal or other materials The process of this can prevent corrosion, improve wear resistance, electrical conductivity, light reflectivity and enhance aesthetics. Nowadays, car owners are mainly young people. After 70s, 80s and even 90s, their main personality, different styles, or gorgeous colors. In the avant-garde new car culture, there are you and my creative passion colliding. Blending classic fashion, highlighting individual style, pursuing ultimate performance,

Electroplated paint cars are actually a process that uses electroplated coatings to replace metallic paint or magnetic paint. The scientific name is vacuum plating, which belongs to physical plating and is environmentally friendly. First put the exterior parts of the car to be painted in the vacuum plating furnace as a target, and then evaporate the metal into a gas state to bombard the target. The thickness of the coating is on the nanometer level. The coating can be precious metals or other colored metals. It can also be chromium. Then add UV light-curing coating and dry it with UV or the like. Various colors can be adjusted by adding fine color in UV paint. High cost, used in high-end cars or concept cars.
