Description

Technical Field

[0001] The invention belongs to the technical field of automobile maintenance, and in particular relates to a glass scratch repairing method. Background Art

[0002] In daily use of vehicles, scratches are unavoidable on the glass of the vehicle body. Scratches not only affect the appearance of the vehicle, but some serious scratches (such as scratches in the driver's field of vision) will also affect driving safety. Therefore, for glass scratches in important parts of the car, it is necessary to achieve a better repair effect. The current repair methods for automobile glass scratches mainly have the following problems: the existing glass scratch repair techniques are mainly aimed at repairing scratches, that is, only focusing on glass scratches during the repair process, which will result in the scratched part of the automobile glass being inconsistent with other surrounding areas after the repair is completed. For example, there is a large difference in light transmittance between the scratched part of the glass and other surrounding areas, which makes the repaired glass appear glare and dizzy at the scratched part. The scratches are only repaired on the surface, but the visual effect of the automobile glass is not restored. Summary of the invention

[0003] The present invention aims to provide a glass scratch repair method, so that after the automobile glass scratch is repaired, not only the physical damage is eliminated, but also the visual effect can be restored to avoid the visual sense of glare and dizziness.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions: A glass scratch repair method is provided, comprising: Determine the location of the glass scratch, the area where the glass scratch is located is the glass repair area, wash away the large particles of sand and dust on the surface of the glass repair area with water, and then remove the oxide layer oil film on the surface of the glass repair area; Observe the depth of the glass scratches, plan a repair area in the glass to be repaired area, repair the repair area as a whole to eliminate the glass scratches, and grind and remove the scratches in order from low to high according to the shape and curvature of the repair area; Use a polishing machine and a polishing restoration disc, combined with a mirror restoration agent, to polish and restore the ground repair area.

[0005] Preferably, the method of eliminating the oil film of the oxide layer on the surface of the glass to be repaired area includes: taking an appropriate amount of oil film oxide layer removal paste and applying it to the glass to be repaired area with a wool disk to eliminate the oil film of the oxide layer on its surface, then spraying a degreasing cleaning agent on the glass to be repaired area, applying it with a wool disk, and then washing off the oil film oxide layer removal paste and degreasing cleaning agent remaining on the surface with water, and then scraping off the moisture on the surface of the glass to be repaired area without any residual watermarks.

[0006] Preferably, the specific method of using the wool disk to construct the glass area to be repaired is as follows: use the wool disk to construct back and forth in a horizontal sequence and make circles three to five times until the oxide layer oil film on the surface of the glass area to be repaired is eliminated.

[0007] Preferably, the sequential grinding from low to high to remove scratches includes: grinding the repair area twice, and during each grinding process, uniformly grinding back and forth horizontally. During the back and forth grinding process, after each horizontal grinding is completed, the next horizontal grinding should be ground along the edge of the previous grinding track.

[0008] Preferably, a coarse abrasive disc is used to remove scratches of two-thirds depth during the first grinding, and a medium abrasive disc is used to remove scratches of the remaining one-third depth during the second grinding. During the grinding process, use a strong flashlight to observe the depth of the scratches while grinding, and do not over-grind the glass surface to cause the glass thickness to become thinner.

[0009] Preferably, the coarse grinding sheet is a No. 360 coarse grinding sheet.

[0010] Preferably, the polishing and restoration of the repaired area after grinding includes: polishing the entire repaired area five to six times, during each polishing process, first apply an appropriate amount of mirror restoration agent on the glass surface, spray an appropriate amount of polishing aid, and slowly construct in a horizontal sequence.

If the effect is not good, continue polishing in the above method until the best effect is achieved.

[0011] Preferably, during each polishing process, the polishing machine should maintain a rotation speed of 1800 to 2200 rpm.

[0012] Preferably, the polishing recovery disc is composed of a medium-sized wool disc and a four-inch or three-inch tray and installed on the polishing machine.

[0013] Preferably, the medium-sized wool disc is constructed using a wool sponge disc that is ten millimeters thick.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the glass scratch repair method is a repair technology that combines manual tools and repair techniques, and has four main processes: washing, observing, grinding, and polishing. The first step is to wash away the oil stains on the glass surface, the second step is to observe the depth of the glass scratches, the third step is to determine the construction plan and determine the repair area, the fourth step is to grind the repair area where the scratches are located to remove the scratches, and the fifth step is to polish and restore the glass surface. After determining the location of the glass scratch and removing the oil stain, plan the repair area, determine the repair area and the curvature of the area based on the repair area, and then use the concept of the repair area combined with the technique and construction data such as the area of ​​the repair area, the depth of the scratch, and the curvature of the area to eliminate the glass scratches. The concept of glass scratch repair is to eliminate scratches by doing area repair, not to eliminate scratches for the sake of eliminating scratches. This construction retains the shape and curvature of the original glass. Repair areas of different areas can use supporting tools of different sizes combined with construction techniques and construction data to achieve efficient elimination of glass scratches, while ensuring that the glass is flat and without dents. Therefore, after repairing car glass scratches, this glass scratch repair method not only eliminates the physical damage of the scratches, but also restores its visual effect to avoid glare and dizziness.

[0015] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings: Figure 1 The figure is a flow chart of an embodiment of a glass scratch repair method of the present invention.

[0016] Figure 2 This is a schematic diagram of planning the repair area in an embodiment of the glass scratch repair method of the present invention. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In one embodiment, a glass scratch repair method is provided. Figure 1 As shown, the glass scratch repair method comprises the following steps: Step S100: determine the location of the glass scratch, the area where the glass scratch is located is the glass repair area, wash away the large particles of sand and dust on the surface of the glass repair area with water, and then remove the oxide layer oil film on the surface of the glass repair area.

[0019] Step S200: Observe the depth of the glass scratches, plan a repair area in the glass to be repaired, repair the repair area as a whole to eliminate the glass scratches, and grind and remove the scratches in order from low to high according to the shape and curvature of the repair area.

[0020] Step S300: Use a polishing machine and a polishing restoration disk in combination with a mirror restoration agent to polish and restore the ground repair area.

[0021] Combination Figure 2 As shown, the glass area 2 to be repaired determined on the automobile glass 1 is larger than the repair area 3, so as to plan the repair area 3. The glass area 2 to be repaired only needs to be cleaned of oil stains, while the repair area 3 needs to be ground and polished after the oil stains are cleaned. The glass scratch 11 is within the repair area 3, and the repair area 3 is within the glass area 2 to be repaired.

[0022] This glass scratch repair method is used to repair scratches on automobile glass. The uniqueness of this method lies in that the repair area is planned according to the location of the glass scratches. The entire area occupied by the repair area is repaired as a whole, rather than repairing the glass scratches individually. This concept of taking the entire area as the repair object can eliminate the glass scratches while ensuring that the surface of the repaired glass is highly consistent with the original curvature and there is no depression on the surface, so that no glare or dizziness will be generated.

[0023] Optionally, in one embodiment of the glass scratch repair method, the aforementioned elimination of the oxide layer oil film on the surface of the glass to be repaired area includes: taking an appropriate amount of oil film oxide layer removal paste and using a wool disk to apply it to the glass to be repaired area to eliminate the oxide layer oil film on its surface, then spraying a degreasing cleaning agent on the glass to be repaired area, and then applying it with a wool disk, and then using water to rinse off the oil film oxide layer removal paste and degreasing cleaning agent remaining on the surface, and then scraping off the moisture on the surface of the glass to be repaired area to leave no residual watermarks.

[0024] In daily use of cars, pollution from automobile exhaust, various greasy drops, etc. in the environment will cause an oxide film to form on the glass surface over a long period of time. The oxide film removal paste combined with a wool disk can be used to remove the oxide film on the surface. The oxide film removal paste can be applied to the glass surface, and then wiped back and forth with a wool disk. The main purpose is to make the oxide film separate from the glass surface, and then wash off the wiped-off oxide film dirt by spraying a degreasing cleaning agent. The surface moisture is removed by scraping dry. There should be no residual watermarks, and you must not wipe it with a towel, otherwise the residual watermarks will cause uneven grinding during subsequent grinding to remove scratches, resulting in uneven glass.

[0025] Optionally, in one embodiment of the glass scratch repair method, the specific method of using the wool disk to work on the glass to be repaired is as follows: use the wool disk to work back and forth in a horizontal sequence and use a circular construction technique three to five times until the oxide layer oil film on the surface of the glass to be repaired is eliminated.

[0026] By using the horizontal back-and-forth construction method and the circular construction method, each area of ​​the glass to be repaired can be effectively wiped to avoid missing any areas, making the removal of the oxide layer oil film more thorough.

[0027] Optionally, in one embodiment of the glass scratch repair method, the aforementioned sequential grinding from low to high to remove scratches includes: performing two grinding operations on the repair area, and during each grinding operation, uniformly grinding back and forth horizontally, and during the back and forth grinding operation, after each horizontal grinding is completed, the next horizontal grinding should be performed along the edge of the previous grinding track.

[0028] By covering the edge of the previous grinding track during the horizontal back-and-forth grinding construction, this edge finishing construction concept with the starting point as the end point can ensure that the grinding area is not missed, and ensure the smoothness of the surface of the glass repair area, without any unevenness, and without causing dizziness and glare lines.

[0029] Optionally, use a coarse grinding wheel to remove two-thirds of the scratch depth during the first grinding, and use a medium grinding wheel to remove the remaining one-third of the scratch depth during the second grinding. During the grinding process, use a strong flashlight to observe the depth of the scratches while grinding. Do not over-grind the glass surface to cause the glass thickness to become thinner. The coarse grinding wheel used is a No. 360 coarse grinding wheel.

[0030] This grinding process of coarse grinding followed by fine grinding is faster in the first two-thirds of the scratch depth, and is finer in the last one-third of the scratch depth, resulting in better surface flatness.

[0031] Optionally, the aforementioned polishing and restoration of the repaired area after grinding includes: polishing the entire repaired area five to six times, during each polishing process, first apply an appropriate amount of mirror restoration agent on the glass surface, spray an appropriate amount of polishing aid, and slowly construct in a horizontal sequence. During the horizontal back and forth polishing process, after each horizontal polishing is completed, the next horizontal polishing is polished along the edge of the previous polishing track to ensure that the edge and middle brightness of each polishing track are the same, and repeat this method five to six times. If the effect is not good, continue polishing in the above method until the best effect is achieved.

[0032] During the polishing process, the rear polishing track is pressed against the side of the front polishing track. This way, the construction can ensure that no polishing is missed, ensuring the flatness of the glass and not causing dizziness and glare.

[0033] Optionally, during each polishing process, the polishing machine should maintain a speed of 1800 to 2200 rpm. Polishing at this speed ensures that the grinding force is good enough and the grinding density is high, which shortens the polishing time and makes the polished glass surface delicate.

[0034] Optionally, use a medium wool disc and a four-inch or three-inch tray to form a polishing restoration disc and install it on the polishing machine. The medium wool disc uses a 10mm thick wool sponge disc for construction. The 10mm wool soft disc fits the glass surface very well during the polishing process. Other appropriate sizes of wool discs can also be used according to the area of ​​the repair area and personal circumstances.

[0035] Based on the above embodiments, it can be seen that the glass scratch repair method is a repair technology that combines manual tools and repair techniques. There are four main processes: washing, observing, grinding, and polishing. The first step is to wash off the oil on the glass surface. The second step is to observe the depth of the glass scratches. The third step is to determine the construction plan and determine the repair area. The fourth step is to grind the repair area where the scratches are located to remove the scratches. The fifth step is to polish and restore the glass surface. After determining the location of the glass scratches and removing the oil, the repair area is planned, and the repair area and the curvature of the area are determined according to the repair area. Then, the glass scratches are eliminated by combining the concept of the repair area with the technique and the area of ​​the repair area, the depth of the scratches, the curvature of the area, and other construction data. The concept of glass scratch repair is to eliminate scratches by repairing the area, not to eliminate scratches for the sake of eliminating scratches. In this way, the construction retains the shape and curvature of the original glass. Repair areas of different areas can use supporting tools of different sizes combined with construction techniques and construction data to achieve efficient elimination of glass scratches. While eliminating glass scratches, it is necessary to ensure that the glass is flat without depression, dizziness, or glare.
