Description:
PRIORITY DATA 
     This application is a continuation of U.S. patent application Ser. No. 12/867,039, filed on Jan. 18, 2011, which is a United States Nationalization of Patent Cooperation Treaty Application PCT/MX2009/000114, filed on Oct. 19, 2009, which claims priority to Mexico Patent Application MX/a/2009/002067, filed on Feb. 24, 2009, each of which are incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to a satin-matte finish glass on either one or both faces, either in whole or in part. The glass may be produced by the process of MX Patent 258791, which is incorporated herein by reference. The resulting satin-matte finish glass in some aspects may have a uniform finish perfectly homogeneous, a soft and smooth touch, with a pleasant aspect to the eye, and can have defined values of transmittance, absorbance, reflectance, and roughness as measured by a series of micrographs taken with an atomic force microscope to show the morphology, structure, and other physical characteristics of the glass. 
     BACKGROUND OF THE INVENTION 
     Nowadays there are different types of satin-matte finish glass, but none of these has the characteristics of the satin-nuanced glass by one or both faces, in whole or in part, produced by the process of MX patent 258,791. 
     For the production of satin-matte finish glass by the traditional method it is by placing a piece of glass on a special table to reveal only the top surface of the glass, being this the atmospheric face and putting in a peripheral edge of wax, put on it a paste or acid solution to achieve the satin-matte finish; acids are left to act for a while and then removed by a final wash to the piece of glass to remove acids, being treated only one piece by time, the resulting finished is not uniform in the treated face. 
     Through this procedure it is not possible to treat the stained face of the sheet of glass, because the residues attached to this side can not attack the standard solutions used. 
     The documents US2002139474, U.S. Pat. No. 6,071,314, US2003127189, U.S. Pat. No. 6,228,211, KR20040087386 (ABSTRACT) KR20030073230 (ABSTRACT) DE29917354U, ES2021250, U.S. Pat. No. 1,529,239, GB190628679, WO0190015, GB1276550, U.S. Pat. No. 4,086,074 and JP1102401 describe processes, compositions, and glasses, but all of these are different to the process and glass of the present invention. 
     The satiny glasses of the present invention have surprising properties that not found in other glasses. These properties are obtained by the manufacturing process of the present invention. These glasses are not satin or suggested in advance, so they are considered to be new and inventive. 
     SUMMARY OF THE INVENTION 
     In one aspect, the present invention provides a satin-matte finish glass that has a uniform finished perfectly homogeneous, a soft and smooth touch with a pleasant aspect to the eye. The finish of the glass products of the present invention may in some aspects be defined using values of transmittance, absorbance, reflectance, roughness and/or a series of micrographs taken with an atomic force microscope to see the morphology and structure of glass-satin, along with some of their physical characteristics. 
     In some aspects the glass product may have a finish with a roughness Ra of 1.04 to 4.07 and a roughness Rz of 6.7 to 23.2 and a (%) of transmittance, a (%) Absorbance and (%) Reflectance. 
     These satin-matte finish glass are useful in the glass industry and construction.

     Measurement Method B 
     The larger sample was termed large glass and the other sample small glass; the faces were called A and B. Five measurements were taken on each side, in each sample. 
     Measurements were made along each of the samples, considering that this measurement falls in the middle of the sample, as follows: 
     The values obtained in each of the measurements were:

     Reflectance and Transmittance 
     The measurements were made at normal incidence in the spectral range of 240-840 nm (UV Vis) with the team FilmTek T 3000. The equipment was calibrated using as a maximum reflectance of silicon wafer polishing and the maximum transmittance of the air. The area that measures the team is the point of a millimeter of diameter. 
     The Table 3 below shows the measured reflectance and transmittance (542 nm) of the sample of satin-matte finish glass

     EXAMPLES 
     Different satin-matte finish glasses are produced by one or both faces, in whole or in part, produced by the process described in MX Patent 258791, the resulting satin-matte finish glass, has a uniform perfectly homogeneous finish, a soft and smooth touch, with an appearance pleasing to the eye. 
     The chemical process for total satin-matte finish or partial, in one or both faces of float glass for the simultaneous production and continues for one or more parts and/or sheets by immersion in acid solution, comprising the following steps: 
     a) Receipt of the pieces and/or sheets of glass;
 
b) Load of the pieces and/or sheets of glass into containers;
 
c) Processing of the pieces and/or sheets of glass by immersion in the following stages:
 
i. Pre-treatment in a washing and cleaning solution.
 
ii. Immersion in an acid solution for satin-matte finish.
 
iii. Immersion in current water to rinse and then rinse by spraying with deionized water.
 
iv. Immersion in an acid solution to stop the reaction and ensure the satin-matte finished.

vii. Immersion in deionized water for washing and then by spraying with deionized water.
 
viii. Immersion (optional) that is reserved for any eventuality;
 
d) Drying of the pieces and sheets of glass;
 
e) Download of the pieces and/or sheets of satin-matte finish glass from the container to stowage racks for storage, transport and distribution.
 
     Stages of immersion in the following solutions: 
     i)—Pre-treatment stage using a washing and cleaning solution composed of 55% deionized water at least 10 microhms, 5% hydrofluoric acid 70%, ie 3.5% acid and 1.5% water and 39.5% sugar dextrose monohydrate, to eliminate all foreign substances to the glass;
 
ii)—Immersion in an acid solution for satin-matte finish that contains 3 to 8% hydrofluoric acid at 70%, equivalent to 2.1% to 5.6% of total hydrofluoric acid, 3 to 8% hydrochloric acid at 30%, equivalent 0.9% to 2.4% total hydrochloric acid, 10 to 30% formic acid 85%, equivalent to 8.5% to 25.5% of the total formic acid, 20 to 40% of deionized water at least 10 microhms, 20 to 50% of anhydrous ammonium bifluoride and 5 to 25% sugar dextrose monohydrate, the speed of immersion is 5.2 meters/minute and the immersion time is from 5 minutes to 30 minutes.
 
iii)—Immersion to rinse and remove the remains of the previous acid solution, which is done by immersion in current water and then spraying with deionized water.
 
iv)—Immersion to stop the chemical reaction on the glass and remove all traces of the acid solution that may exist that contains 3 to 5% hydrochloric acid at 30%, equivalent to 0.9% to 1.5% of the total acid, 3 to 5% hydrofluoric acid at 70%, equivalent to 2.1% to 3.5% of hydrofluoric acid and water from 95 to 97%, this solution should be between 0.5 and 1.0 milliequivalents per liter, a pH of 2.1 to 3.2, the time immersion varies from 30 seconds to 3 minutes depending on the number of sheets of glass.
 
v)—Immersion rinse and remove the acid solution above, which is done by immersion in current water and then spraying with deionized water;
 
vi) and vii)—Stages of immersion to wash and remove the remains of the acid solution, which is done by immersion in deionized water and then by spraying deionized water; and
 
viii)—Immersion in case of any eventuality or necessity can be water or acid solution.
 
     Drying of the pieces and/or sheets of glass is done in a drying chamber at a temperature of 30 to 60° C., or can also be done to the environment temperature, or through a washer/dryer vertically or horizontally, or through a tunnel furnace operated with natural gas, LP gas and/or electrical resistance, without affecting the quality of the glass.

     RESULTS AND CONCLUSIONS 
     Results for Clear Satin Glass 
     The clear satin glass by both faces reduces visible light transmittance for glass thicknesses of 2 mm, from 87% up to 77% for a thickness of 9.5 mm, the transmittance gradually reduced as the thickness increases. While if it is only one face, there is no significant reduction in transmittance, but higher in thicknesses of 6 mm, reaching similar values to 9.5 mm (76%) in case of satin of the stained face and 84% when it is only treated the atmospheric face. 
     However, for values of wavelengths in the infrared range (1100 nm), the transmittance is reduced steadily from a value of 80% for thickness of 2 mm of glass, up to 63% for thicknesses of 6 mm. Something similar occurs for the treatment of only one of the two faces, although the reduction in transmittance reaches the 53% for the thickness of 6 mm. 
     Results of Satin, for Different Type Glass 
     If applied satin to different kinds of glass, using 6 mm thick, as a reference, glossy glass displays transmittances of visible light ranging from 80% to clear satin glass up to 40% for gray satin glass. 
     Notably, the transmittance for infrared reduced even more for green satin glass (12%), from a value of 70% transmittance exhibited by the same satin glass in the case of visible light. Blue satin glass also exhibits significant variations in the transmittance, of 54% for visible light to 31% for infrared. 
     Similar trends are observed for satin glass of only one of the two faces. 
     Results of Roughness of Different Type of Glass 
     Roughness measurements were made on samples of glass, using a TR Surface Roughness Tester, brand Time. 
     From the photographs you can see a remarkably homogeneous roughness, so the resulting satin-matte finish glass is a uniform finish perfectly homogeneous, a soft and touch smooth with a pleasant aspect to the eye, which do not have, like other satin glasses. 
     Advantages 
     By the thermal characteristics and the obtained results of tests carried out by the glossy glass of this invention, one obtains a surprisingly satin glass with excellent capture sunlight for applications in photovoltaic cells and solar heaters, because we can apply different treatments for different types of filters for different wavelength ranges of the electromagnetic spectrum. And in the treatment of satin-matte finish on both faces of the glass sheet, get a glass with excellent properties for application as a thermal insulator, and not let infrared light but it let the visible and ultraviolet light. 
     Many applications for such glass exist in a variety of industries and areas, including the construction industry, at home, in decorations, in the glass industry, etc., in which need glasses satin-matte finish glasses with a perfectly uniform finished and a soft and touch smooth with an appearance pleasing to the eye and with defined values of transmittance, absorbance, reflectance and roughness, with no other satin glass, currently known.
