Abstract

PURPOSE:To prevent the staining of a glass product when held by hand and to impact moderate gloss to the surface, by dipping the glass product in a corrosive solution containing hydrogen fluoride, etc. to give a matte surface thereto, dipping the resultant glass product in a corrosive and glazing solution to glaze the surface. CONSTITUTION:A glass product is dipped in a corrosive solution consisting of hydrogen fluoride, ammonium fluoride, distilled water and glassy fine powder for a suitable time, and washed with water to matte the surface thereof. The resultant glass product is then dipped in a corrosive glazing solution consisting of hydrogen fluoride, sulfuric acid and nitric acid for a suitable time and washed with water to corrode fin unevennesses on the roughened surface formed by the matting, smooth somewhat the surface and develop elegant image by impartment of a moderate gloss thereto. Since the unevennesses on the surface are small, the following advantage is produced; Dirt from hands, sweat, etc. will not readily enter recessed parts, and the glass product is not easily stained.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a method for surface treatment of glass products, in which the surface of the glass product is matted, the matted portion is slightly polished, The present invention relates to a surface processing method for glass products, which forms the glass products in such a way that when the glass products are held by hand, they are resistant to smudges and fingerprints, and give off an elegant image with appropriate gloss.

``Technical disadvantages of the invention■ and its problems'' Traditionally, glass products with a matte coating on the surface have an elegant appearance and have been very well received by consumers. be.

However, when this glass product was held in the hand, it became very ugly with fingerprint-like spots, and it was also easy to get dirt from the hands, which was very noticeable.

[Objective of the Invention 1] Therefore, in view of the above-mentioned points, the present invention aims to prevent hand stains, fingerprints, etc. from being deposited on the surface of a product treated with Gloss 811, and to create an elegant image with an appropriate level of gloss. It was created with the purpose of doing so.

[Summary of the Invention 1 In order to achieve the above object, the present invention involves soaking a glass product in a corrosive solution consisting of hydrogen fluoride, ammonium fluoride, distilled water, and glass-based fine powder for an appropriate period of time, washing it with water, and then washing it with water. , soaked in a corrosive polishing solution made of hydrogen fluoride, sulfuric acid, and nitric acid for an appropriate amount of time,
Furthermore, it is necessary to wash it with water again.

[Embodiments of the Invention] The present invention will be described in detail below with reference to the drawings.

That is, as shown in the figure, first, the glass product undergoes a so-called frosting process to make the surface glossy.

This Frost 110■ process uses 30 to 60% hydrogen fluoride,
Glassware is immersed for 30 minutes and 60 seconds in a floss solution, which is an etchant made of 30-60% ammonium fluoride, 5-10% distilled water, and 5-10% glass-based fine powder. be.

Glass products that have undergone this frosting process are washed twice and then dried.

Next, the dried glass products undergo a polishing process.

This polished culm contains 40 to 70 χ hydrogen fluoride and 2 sulfuric acid.
This is done by immersing the dried glassware for 30-60 seconds in an etching polish solution made of 5-60% nitric acid and 5-10x nitric acid.

In other words, this process corrodes the minute irregularities on the surface that have become rough due to the frosting process, making them slightly smoother. 1. Glass products that have gone through this polishing process are then washed twice with water. It is something that is completed over time.

In this case, before performing the frosting step,
Glass products should be cleansed with acid or water beforehand, as there should be no dirt on the surface.
! The portions that will not be processed are appropriately masked.

Incidentally, among the above-mentioned processed culms, the same results can be obtained even if the drying after the washing step after 70 strokes and about 11 times is omitted.

[Effects of the Invention] Since the present invention is configured as described above, it is difficult for hand marks and fingerprints to stick to the surface of glass products that have been subjected to a matte finish.
In addition to the traditional matte elegance, it also has a moderate luster, creating an elegant image.

That is, the surface of the glass product becomes rough by immersing the glass product in an etchant made of hydrogen fluoride, ammonium fluoride, distilled water, and glass-based fine powder for a suitable period of time.

After washing the corrosive solution off the surface of the glass product with water, the glass product is immersed in a corrosive polishing solution made of hydrogen fluoride, sulfuric acid, and nitric acid for an appropriate amount of time, and finally washed with water again to remove the corrosive polish. Once the liquid is washed off, the corrosive polishing liquid can be used to easily etch away minute irregularities of 1-+ on the rough surface of the glass product, making it slightly smoother. As a result, the surface appears more glossy than the surface matted by the corrosive solution, creating an elegant image with a more appropriate level of gloss than a completely matted surface.

This is because the corrosive liquid makes the unevenness smaller than on the matte surface, making it difficult for dirt, sweat, etc. to get into the recessed areas, and making it harder for dirt and fingerprints to stick to the surface.

Furthermore, if letters, designs, etc. are printed with gold or silver ink on a surface that has been corroded only by the polishing liquid, the printed letters, designs, etc. will simply be in a matte state. However, since the surface polished with the corrosive polishing liquid has small irregularities, the printed matter has a shiny gold or silver color, and very beautiful letters, designs, etc. can be formed.

As explained above, according to the present invention, it is possible to prevent hand marks, fingerprints, etc. from forming on the surface of a glass product that has been subjected to a matte finish,
What's more, it can create an elegant image with just the right amount of gloss, and when letters, designs, etc. are printed on the surface with gold or silver ink, the luster of the gold or silver ink will not be lost. It creates an image of being extremely elegant and has a moderate luster, and has excellent effects such as stimulating the consumer's desire to purchase.
