Definitions
- the present invention relates to hollow glass articles, such as bottles, flasks, or jars, having a high light transmission and a strong protection against damage due to radiation.
- ultraviolet (UV) radiation especially solar radiation
- UV radiation can interact with many liquids, sometimes degrading their quality. This is for example the case of certain liquid foods, among which some wines such as Champagne, or beer, whose color and taste can be altered.
- Glass hollow objects responding to this constraint are extremely common, but they generally have strong colorations, so a very low light transmission.
- wine or beer is often packaged in bottles of amber or green hue, these colors being obtained by the addition of dyes such as chromium oxide or sulphides of transition elements, such as sulphides of iron.
- dyes such as chromium oxide or sulphides of transition elements, such as sulphides of iron.
- These tinted containers however have the disadvantage of masking the color of the liquid they contain. In some cases, it may be desirable, mainly for aesthetic reasons, to be able to fully appreciate the coloring of the contents, and thus to have hollow glass objects having both a high light transmission and a neutral hue.
- WO2005 / 075368 discloses glass compositions capable of solving this problem. These compositions, which comprise vanadium oxide and manganese oxide, make it possible to obtain hollow glass objects having both low ultraviolet transmission (for wavelengths below 380 nm) and strong light transmission (in the wavelength range between 380 and 780 nm). However, it appeared that the protection conferred by these objects could in certain respects be insufficient in the long term, in particular for liquids such as white wines, still or effervescent, especially Champagne.
- the invention aims to increase the shelf life of these liquids, contained in glass containers, while allowing to visualize the appearance of said liquids.
- the subject of the invention is a hollow glass object having, for a thickness of 5 mm, an overall light transmission greater than or equal to 70%, said overall light transmission being calculated taking into consideration the illuminant C such as defined by the ISO / IEC 10526 standard and the CIE 1931 colorimetric reference observer as defined by ISO / CIE 10527, and a filtering capacity greater than or equal to 65%, especially 70%, said filtering power being defined as being equal to the value of 100% less the arithmetic average of the transmission between 330 and 450 nm.
- the object according to the invention is such that its chemical composition is of the soda-lime-silica type and comprises the following optical absorbing agents in a content varying within the weight limits defined below:
- the glass object according to the invention preferably has one or more of the following properties, always calculated for a thickness of 5 mm: a transmission for a wavelength of 440 nm less than or equal to 70%, preferably 65% including 60% and even 55% or 50%, or 45%, or 40% and even 35%.
- a transmission for a wavelength of 440 nm less than or equal to 70%, preferably 65% including 60% and even 55% or 50%, or 45%, or 40% and even 35%.
- an ultraviolet transmission calculated according to ISO 9050, less than or equal to 20%, preferably 15%, in particular 10% and even 5%.
- these optical properties are those of the single glass object, thus excluding any organic or mineral coating.
- the optical properties depend in known manner on the thickness of the glass. It's obvious that the glass object according to the invention does not necessarily have a thickness of 5 mm. On the other hand, it is important that the essential optical properties are respected for an equivalent thickness of 5 mm. In the case where the thickness of the object is not equal to 5 mm, it is easy to calculate these properties for an equivalent thickness of 5 mm from a measurement made on the object, taking into account its real thickness.
- compositions are expressed in percentages by weight, and the content of an oxide of a given metal corresponds to the total content of this metal oxide, without prejudging the actual degree of oxidation of the metal ion in question.
- preferred levels, minimum or maximum, are given it is understood that any range resulting from a combination of a minimum content and a maximum content is expressly part of the present description.
- the composition preferably comprises one or more of the following limitations, alone or in combination: preferably, the iron oxide content is greater than or equal to 0.02%, especially 0.03% and even 0.04%, or 0.05% or 0.06% and / or less than or equal to 0.14%, in particular 0.13% and even 0.12%, or even 0.11% or 0.10%.
- the content of titanium oxide is preferably greater than or equal to 0.6%, especially 0.7% and even 0.8% or 0.9%, or 1% and / or less than or equal to 2.5% including 2.4%, or even 2.3% and even 2.2% or 2.1%.
- the sulphide content is preferably greater than or equal to 0.0015%, especially 0.0020% and / or less than or equal to 0.0040%, or even 0.0035%.
- Redox defined by the ratio of the molar content of ferrous oxide (expressed as FeO) to the molar content of total iron (expressed as Fe2O3), which is an indicator of the redox state of the glass, is preferably greater or equal to 0.5, especially 0.55 and even 0.6.
- Redox is generally controlled with oxidizing agents such as sodium sulfate, and reducing agents such as coke, whose relative contents are adjusted to achieve the desired redox.
- the composition according to the invention preferably comprises no absorbing agent for a wavelength of between 300 and 1000 nm other than the iron and titanium oxides and the sulphide ions.
- composition according to the invention preferably does not contain agents chosen from the following agents: oxides of transition elements such as CoO, CuO, Cr 2 ⁇ 3, V 2 O 5 , MnO 2 , oxides rare earths such as CeO 2 , La 2 ⁇ 3, Er 2 ⁇ 3, or
- Nd 2 ⁇ 3 or else the elementary coloring agents such as Se, Ag, Cu.
- optical absorbing agents within the limits of the invention makes it possible to confer the desired properties and also to better adjust the optical and energetic properties of the glass.
- These properties result indeed from a complex interaction between the various agents whose behavior is further linked to the glass matrix used and their oxidation state. This is particularly the case for the compositions according to the invention, which contain at least two elements existing under several valences.
- silico-soda-lime is used here in the broad sense and concerns any glass composition consisting of a glass matrix which comprises the following constituents (in percentage by weight): SiO 2 64 - 75%
- the soda-lime glass composition may comprise, in addition to unavoidable impurities contained in particular in the raw materials, a small proportion (up to 1%) of others. constituents, for example agents assisting with the melting or refining of glass (SO3, Cl, Sb 2 ⁇ 3, As 2 Os) or from a possible addition of recycled cullet in the batch.
- the silica is generally kept within narrow limits for the following reasons. Above 75%, the viscosity of the glass and its ability to devitrify greatly increase which makes it more difficult to melt and pour on the molten tin bath. Below 64%, the hydrolytic strength of the glass decreases rapidly and the transmission in the visible also decreases.
- Alumina Al 2 O 3 plays a particularly important role in the hydrolytic resistance of glass.
- the alumina content is preferably greater than or equal to 1%.
- the alkaline oxides Na 2 O and K 2 O facilitate melting of the glass and allow its viscosity to be adjusted at high temperatures to keep it close to that of a standard glass.
- K 2 O can be used up to 5% because beyond this arises the problem of the high cost of the composition.
- the increase in the percentage of K 2 O can be done, for the most part, only to the detriment of Na 2 O, which contributes to increasing the viscosity.
- the sum of the contents of Na 2 O and K 2 O, expressed in weight percentages, is preferably equal to or greater than 10% and advantageously less than 20%. If the sum of these contents is greater than 20% or if the Na 2 O content is greater than 18%, the hydrolytic resistance is greatly reduced.
- the glasses according to the invention are preferably free of lithium oxide Li 2 O because of its high cost.
- the alkaline earth oxides make it possible to adapt the viscosity of the glass to the conditions of preparation.
- MgO may be used up to about 10% and its removal may be offset, at least in part, by an increase in Na2O and / or SiO2 content.
- the MgO content is less than 5% and particularly advantageously less than 2% which has the effect of increasing the absorption capacity in the infrared without affecting the transmission in the visible.
- Low levels of MgO also make it possible to reduce the number of raw materials required for melting the glass.
- BaO has a much lower influence than CaO and MgO on the viscosity of glass and the increase in its content is mainly to the detriment of alkaline oxides, MgO and especially CaO. Any increase in BaO helps to increase the viscosity of the glass at low temperatures.
- the glasses according to the invention are free of BaO and also of strontium oxide (SrO), these elements having a high cost.
- the glass composition according to the invention is capable of being melted under the conditions of production of glass intended for forming hollow bodies by pressing, blowing or molding techniques.
- the melting generally takes place in flame furnaces, possibly provided with electrodes for heating the glass in the mass by passing the electric current between the two electrodes.
- the addition of the optical absorbing oxides can be carried out in the furnace (this is called “pool coloration”) or in the channels carrying the glass between the furnace and the forming plants (this is called “feeder coloration”).
- the coloring feeder requires a particular installation of addition and mixing but on the other hand offers flexibility and responsiveness particularly appreciated when the production of a wide range of colors and / or special optical properties is required.
- the optical absorbing agents are incorporated in glass frits or agglomerates, which are added to a clear glass to form after homogenization the glasses according to the invention. Different frits may be used for each added oxide, but it may be advantageous in some cases to have a single frit comprising all useful optical absorbers.
- the levels of optical absorbing oxides in the frits or agglomerates employed be between 5 and 30%, so as not to exceed melting rates of frit in the molten glass greater than 10%, especially 5%, and advantageously 2%. Beyond that, it becomes indeed difficult to properly homogenize the molten glass while retaining strong runs compatible with a low overall economic cost of the process.
- the invention therefore also relates to a method for manufacturing a glass having a composition according to the invention, comprising a step of melting a part of the vitrifiable mixture, a step of transporting the molten glass to the forming device during which oxide is added to said molten glass by means of sintered glass or agglomerates, at least a portion of the optical absorbing agents being provided to the composition during this step, and a step of forming said glass to obtain an object hollow.
- all of the optical absorbing agents, except iron, are provided to the composition during the step of transporting the molten glass to the forming device.
- the subject of the invention is also a method for manufacturing a glass having a composition according to the invention, comprising a step of melting the vitrifiable mixture in a melting furnace, said vitrifiable mixture providing all the oxides included in said composition, and a forming step.
- any method for obtaining a hollow glass object is usable.
- the object according to the invention is preferably a bottle, in particular likely to contain or containing beer or white wine, quiet or effervescent, especially Champagne.
- the values of the following optical properties calculated under a glass thickness of 5 mm are given from experimental spectra: the overall light transmission (TL C ), calculated between 380 and 780 mm.
- the filtering power (denoted by PF), defined as being equal to the value of 100% minus the arithmetic average of the transmission between 330 and
- T 440 the transmission for a wavelength 440 nm
- Table 1 Also shown in Table 1 are the weight levels of optical absorbing agents.
- compositions appearing in Table 1 are made from the following glass matrix, the contents of which are expressed in percentages by weight, this being corrected at the silica level to adapt to the total content of added coloring agents.
