Definitions
- the invention relates to a textured substrate with high transparency and low scattering, especially for horticultural greenhouses.
- the invention will be more particularly described with regard to a transparent substrate for horticultural greenhouses, without being limited thereto, and applies to all applications requiring a high hemispheric transmission (TLH), a high light transmission (TL) and a weak Haze (H).
- TH high hemispheric transmission
- TL high light transmission
- H weak Haze
- smooth surface glazing is mainly used because of its very strong hemispheric light transmission.
- a smooth surface is a surface for which the surface irregularities are smaller than the wavelength of the radiation incident on the surface, so that the radiation is not deflected by these surface irregularities.
- the incident radiation is then specularly (or evenly) transmitted by the surface so that radiation incident on the glazing with a given angle of incidence is transmitted by the glazing with a transmission angle depending on the angle of incidence. impact.
- a specular transmission implies that an incident ray is transmitted as a single ray.
- a transmitted ray always includes a diffuse component, the latter being however negligible in the case of a so-called specular transmission.
- textured glasses for which the surface irregularities vary on a scale larger than the wavelength of the radiation incident on the surface.
- the incident radiation is then diffusely transmitted by these surfaces.
- the transmission by a glazing is said diffuse when radiation incident on the glazing with a given angle of incidence is transmitted by the glazing in a plurality of directions.
- This diffuse transmission has a positive impact on the horticultural production of the susceptible crops mentioned above.
- the diffusion effect avoids hot spots on the plants and allows better penetration of light in all areas of the greenhouse. In other words, it provides a more homogeneous lighting.
- the texture of such glasses is obtained by a rolling method, at least one of the metal cylinders having a textured surface that corresponds to the negative of the texture to be obtained on at least one face of the glass.
- the reasons for the texture are, for example, bumps or prisms such as cones or pyramids which can register at the base of the substrate in a circle.
- the patterns in relief are derived from holes / cavities / pits made, generally in the form of circles, formed on the surface and in the thickness of the substrate, and obtained by rolling rollers having raised shapes.
- the average slope (Pm) of the texture patterns was measured with a device marketed by STIL and referenced Micromesure 2 TM.
- the period (Rsm) and the height (Rz) of the patterns were measured according to the ISO 4287: 1997 standard with a Mitutoyo SJ-400 TM apparatus, this apparatus being equipped with a 1400 mm pencil and implementing Gaussian filters with cuts (or base length, cut-off in English) at 25 ⁇ and 8 mm (deletion periods less than 25 ⁇ and greater than 8 mm).
- the period Rsm of a profile (that is to say along a line segment) of a surface is defined by the relation: where Si is the distance between two zero crossings (center line) and amounts, where n + 1 is the number of zero crossings going up in the profile considered.
- This parameter Rsm is representative of the distance between peaks, that is to say the pitch of the texture parallel to the general plane of the substrate.
- the Rsm measurements are made over a distance of at least 40 mm. For any point on the textured surface, the Rsm around this point corresponds to the arithmetic mean of the Rsm for 10 star-shaped profiles starting from point considered. For the calculation of the Rsm around a point, values greater than or equal to 40 mm are removed.
- An average Rsm of a textured surface is also defined by calculating the arithmetic mean of the Rsm around a point, the points being chosen on a square grid with a pitch of 5 cm.
- the height Rz of a profile that is to say along a line segment, of a surface is the average of the five largest heights of the profile. Height is defined as the distance between the highest peak and the lowest valley over a sampling length of the profile.
- the parameter Rz is therefore representative of the average maximum height of the profile.
- T H EM hemispheric transmission
- T H EM hemispheric transmission
- the strong diffusion and homogeneous distribution of light that are sometimes also sought they correspond to the blur of the glazing which is determined by the value of Haze, says H.
- the Haze is the ratio between the diffuse transmission and the total transmission of the glazing .
- TLH and Haze are measured according to the methods detailed in "Processions in Horticultural Systems, Eds: S. Hemming and E. Heuvelink, Acta Hort.956, ISHS 2012".
- the patent application WO2016 / 170261 filed in the name of the Applicant, describes textured glasses developed with the objective of presenting very high Haze values, greater than 60%, with a limited loss of TLH. These glasses are intended to stand out from the glass brand Albarino-T TM, marketed by the Saint-Gobain Group, whose Haze is considered too low. Note that the Albarino-T TM brand glass is textured on its two opposite sides by hot rolling between two textured rolls. As specified in the examples, its faces respectively comprise texture patterns with a Pm of 2 ° and 1.5 °, the sum of the two average slopes being therefore equal to 3.5 °, for a Haze in transmission of a value from 20% to 1.5 °.
- Textured lenses such as those described in WO2016 / 170261 have the disadvantage of having a lower hemispheric light transmission compared to the same non-textured glass, which opposes the desired primary function of a high light transmission glass for the horticultural production. Note that a gain or loss of 1% of TLH is already very sensitive.
- the present invention meets this need, and concerns in at least one particular embodiment a transparent substrate comprising a texture in relief on at least one of its two main faces, such that
- the average slope P m in degree of this textured face is less than 2 °
- each of the faces having a respective average slope (Pml, Pm2), the sum of the two average slopes of the respective faces is less than 3 °, preferably less than 2.5 °.
- the slope at a point on the surface of a sheet designates the angle formed between the tangent plane at this point and the general plane of the substrate.
- the measurement of the slope at a point is made from the measurement of the variation of height in the vicinity of this point and with respect to the general plane of the substrate.
- the average slope Pm of the surface is determined from the measurement of slopes at points distributed over a surface in a square mesh of period 20 ⁇ .
- a substrate according to the invention has a very important TLH hemispherical transmission, and thus approaches that of a floated glass with smooth surfaces, while maintaining a textured surface.
- This hemispherical transmission TLH increases at the same time that the Haze decreases, and vice versa.
- the invention is based on a new and inventive concept of setting an upper limit value of average slope Pm to ensure a satisfactory haze, because minimal.
- a slope value of less than 2 ° makes it possible to obtain a surface whose Haze is less than 10% at 1.5 °, which is considered satisfactory.
- Such a surface has fine and discrete texturing with tight patterns.
- the substrate is characterized in that:
- the average slope Pm in degree of this textured face is less than 1.8 °, preferably less than 1.7 °, still more preferably less than 1.6 °, still more preferably less than 1 , 5 °, still more preferably less than 1.4 °, still more preferably less than 1.3 °.
- each of the faces having a respective average slope (Pml, Pm2), the sum of the two average slopes of the respective faces is less than 2.3 °, preferably less than 2.1 °, still preferably less than 1.9 °, still more preferably less than 1.7 °, still more preferably less than 1.5 °, still more preferably less than 1.3 °.
- the upper Haze limit value to be obtained is preferably set at 5% at 1.5 °, and preferably at decreasing Haze values.
- the refractive index of the material comprising the texture is between 1.4 and 1.65 at a wavelength of 587 nm.
- the material comprising the texture is made of mineral glass, and preferably comprises iron oxide in a total weight content (expressed as Fe 2 O 3 ) of at most 0.030%, especially from plus 0.020%, or even 0.015%, and is preferably of silico-sodocalcic type with the following mass composition:
- the present characteristics relate to glasses of the extra-clear type, and more particularly to the Diamant TM and Albarino TM canopy dies, marketed by Saint-Gobain.
- These glass substrates have the advantage of having a light transmission greater than 90.5%, still more preferably greater than 90.8%, still more preferably greater than 91.0%, still more preferably greater than 91.2%, even more preferentially greater than 91.4%. They are thus distinguished from so-called "clear" glasses whose light transmission is generally less than 90%. Throughout the text, the light transmission is measured in% according to standard NF EN410- 2011 (illuminant D65, 2 ° Observer) with a Lambda950 TM spectrometer from Perkin Elmer.
- the texture of said at least one substrate comprises patterns whose period is such that the average Rsm is less than 5 mm, preferably less than 2 mm, more preferably less than 900 ⁇ , still preferably less than 850. ⁇ , still preferably less than 800 ⁇ , still preferably less than 750 ⁇ , still preferably less than 700 ⁇ , still preferably less than 650 ⁇ , still more preferably less than 600 ⁇ , more preferably less than 550 ⁇ .
- the surface of a substrate may comprise deformations in the form of corrugations having a very important period, of the order of ten millimeters. During roughness measurements, these corrugations are suppressed via the implementation of Gaussian filters with cutoff above a given value of period (in this case, 8 mm). These undulations are generally masked at the sight of an observer by the texturing of the surface considered.
- the substrate is characterized in that:
- the average slope Pm in degree of this textured face is greater than 0.3 °, preferably greater than 0.4 °, preferentially greater than 0.5 °, still more preferably greater than 0, 7 °, still more preferably greater than 0.9 °, still more preferably greater than 1.0 °, still more preferably greater than 1.1 °.
- each of the faces having a respective average slope (Pml, Pm2), the sum of the two average slopes of the respective faces is greater than 0.6 °, preferably greater than 0.8 °, still preferably greater than 1.0 °, still more preferably greater than 1.1 °.
- the substrate comprises an antireflection coating on one or both main faces, preferably reported against said at least one textured face.
- This antireflection effect can be obtained by the deposition of a layer or of several layers forming a stack, for example by deposition sol-gel liquid or any other suitable technique known.
- the antireflection effect is chosen to be effective at wavelengths 400-700 nm.
- An antireflection coating (antireflection layer or antireflection layer stack) generally has a thickness in the range of 10 to 500 nm.
- the antireflection layer is such that it matches the texture of the glass without modifying it.
- the texture is obtained by rolling the constituent material of the substrate between two rollers, a first roll having a smooth surface and a second roll having a textured surface, or both rolls having a textured surface.
- the rolling is hot, especially in a temperature range of 800 to 1300 ° C.
- the textured glass of the invention has characteristics extremely close to a float glass which is the one usually used. for horticultural greenhouses because of a very high TLH.
- the laminating manufacturing method allows the use of specific glass compositions improving the optical properties of light transmission (high TL value), even though these compositions with high light transmission can not be used in the float process because they are incompatible. with the tin bath used in the float process.
- the substrate is made of a totally monolithic material.
- the texture may be made of a first material attached to a substrate of a second material.
- the texture is made in a first relatively thin material comprising the texture and associated with a second material giving rigidity to the entire substrate. It is appropriate for this first material to be present in a minimum thickness enabling the relief patterns to be produced.
- the difference in the refractive indices of these two materials does not exceed 0.2 and more preferably does not exceed 0.1. In this case, it is a combination of several materials when the texture is made by embossing a sol-gel layer deposited on a transparent substrate, in particular glass.
- the substrate may also comprise more than two materials.
- the distribution of the texture extends over the entire surface of the substrate.
- the invention also relates to a horticultural greenhouse equipped with such a substrate.
- the invention also relates to a method of manufacturing such a substrate by rolling between two rollers, either between a smooth surface roller and a patterned textured roll, or between two patterned textured rolls, in particular the textured roll or rolls having printing patterns having an upper average slope, preferably greater than 1 °, to the average slope of the associated units obtained on the substrate.
- the texture of the substrate obtained by rolling is a function of the shape of the patterns of the printing surface of the roll and their roughness, as well as parameters related to the method such as the height of the roll, the pressure exerted by the roll, the speed of scrolling of the material to be rolled.
- the textured roll or rolls have in particular printing patterns having a higher average slope, preferably greater than 1 °. at the average slope of the associated units obtained on the substrate.
- the invention therefore proposes a production of horticultural glass textured by a laminating process with a specific texturing, replacing float glass usually used in this horticultural glass market.
- the rolling method is economical and the glass with the texturizing characteristics of the invention advantageously has properties equivalent to float glass.
- the patterned textured roll or rolls are obtained by electroerosion.
- EDM electrical discharge machining
- this machining method is suitable for the texturing of the rollers that other known machining techniques using a laser or a wheel, that the skilled person could have been encouraged to implement .
- FIG. 1 represents a schematic sectional view of a first example of textured substrate according to the invention comprising a single textured surface obtained by rolling;
- Figure 2 is a photograph in top view of the example of Figure 1;
- FIG. 3 is a schematic sectional view of a second example of textured substrate according to the invention, comprising its two opposite textured faces.
- the textured substrates 1 and 3 illustrated in the respective figures 1 and 3, in section according to their edge, are two respective embodiments of the invention, the first example of substrate having only one textured main face, while the second example presents its two opposite main faces textured.
- the textured substrates of the invention are such that:
- the average slope P m in degree of this textured face is less than 2 °, and when the substrate is textured on its two faces, each of the faces having a respective average slope Pml, Pm2, the sum of the two average slopes of the respective faces is less than 3 °, preferably less than 2.5 °.
- the patterns of a textured face are distributed over the entire surface of the substrate.
- the textured substrate 1 (Example 1) is made of a silicosodocalcic mineral glass having a thickness of between 3 and 5 mm, obtained by hot rolling between two rollers whose upper roll was smooth surface, while the lower roll was surface-coated. textured printing.
- Substrate 1 has its first planar face 10 and its opposite second face 11 textured.
- the raised patterns of the textured face 11 correspond to the negative patterns of the textured surface (printing patterns) of the roll.
- the patterns of the textured face of Example 1 shown diagrammatically in FIG. 1 and illustrated in FIG. 2 are formed of a multiplicity of alternation of bumps and holes obtained using a roll comprising patterns / shapes in protrusion, here with circular base.
- the roughness of the textured surface of the printing roll for Example 1 has the following characteristics on a profile of a given length, the measurements having been made according to ISO 4287: 1997:
- the substrate 1 obtained in this example 1 has a relief texture such that the average slope Pm is 1 °.
- the texture is such that the period according to the average Rsm is 0.53 mm and the height Rz is 5.6 ⁇ .
- the substrate 2 of the invention (example 2) is made of a silicosodocalcic mineral glass obtained by hot rolling between two rollers with a textured printing surface, the substrate having its two opposite faces 20 and 21 textured.
- the rollers used for Example 2 each have the same textured printing surface and whose roughness is that defined in the roll of Example 1.
- the substrate 2 obtained has a texture in relief such that the average slope Pml of the first surface (surface obtained by the lower roller) is 1 ° and the average slope Pm2 of the second surface (surface obtained by the upper roller) is 1 °, the sum of the average slopes being 2 (Pml + Pm2).
- the loss of TLH is equal to the difference in TLH between that of the measured substrate and a reference flat glass TLH.
- the flat float glass taken as reference is the so-called DIAMANT TM glass sold by Saint Gobain which has a high TLH of 84% and a Haze of 0.
- Example 3 which is a comparative example is a commercial glass, Albarino-T TM.
- This glass of Example 3 has its two opposite textured faces via a roll of the same roughness with laminating process parameters leading to a substrate respectively having a first average slope Pml of 2 °, and a second average slope Pm2 of 1, 5 °, which generates the sum of its average slopes equal to 3.5 °.
- Example 4 which is a comparative example is a substrate having a single textured face, the texture of which is that corresponding to that obtained for one of the faces of the Albarino-T TM glass of Comparative Example 3.
- This substrate has a mean slope equal to 2 °.
- Example 5 which is a comparative example is a substrate of which one of the textured faces was obtained by the textured surface printing roll of Examples 1 and 2, and whose opposite textured face was obtained by an identical roll. to that providing one of the textured surfaces of the Albarino-T TM glass of Example 3.
- the substrate of Example 5 has a first average slope Pml of 1 °, and a second average slope Pm2 of 2 °, generating the sum of average slopes equal to 3 °. Table 1
- Example 1 of the invention with a mean slope of less than 2 °, in particular equal to 1 °, is entirely suitable for obtaining the desired result, a high TLH with a loss of TLH of less than 1%. (especially 0.3%), and a Haze of 5%, less than 10%.
- Example 2 of the invention with a sum of average slopes less than 3 °, in this case equal to 2 °, meets the desired results with a loss of TLH of 0.5% (therefore less than 1% ) and a Haze of 8% (thus less than 10%).
- Comparative Example 3 shows that with average slopes on each textured face of 2 ° and 1.5 ° respectively giving a sum of average slopes which is not less than 3 °, the result is not reached, the Haze of the substrate being too significant because of 19%.
- Comparative Example 4 with a single textured face which has an average slope of 2 ° certainly has a loss of TLH of less than 1% but already has a significant diffusion greater than 10%. This substrate is not suitable.
- Comparative Example 5 shows that with two textured faces of average slopes, however weak 1 ° and 2 ° respectively, but whose sum is not less than 3 °, the result is not reached.
- the loss of TLH is certainly 0.8% but the Haze is too significant with 14% (thus greater than 10%).
- Table 2 gives an estimate of the Haze value in 1.5 ° transmission of an extra-clear Albarino matrix comprising a single textured surface, as a function of its average slope Pm. This estimate is based firstly on an approximation made of the definition of the slope as a function of the roughness parameters, according to the following equation:
- the parameter Rz corresponds to the maximum height of the profile over an evaluation length I
- the parameter Rsm corresponds to an average period of the profile over an evaluation length I.
- an approximation can be made of Rz as being equal to the average height over the evaluation length.
- the estimate of the Haze value is further based on a second hypothesis made of the distribution of slopes having, when considered as a whole, the average value of desired slope Pm (target value).
- target value the average value of desired slope Pm (target value).
- the measured sample having the average slope closest to this target value is first selected from among existing sample measurements.
- a coefficient of expansion is then applied to the slope distribution function of this sample to simulate a new slope distribution with the average slope target value.
- Table 3 gives an estimate of the Haze value in 1.5 ° transmission of an extra clear Albarino matrix comprising two opposite textured surfaces, as a function of the sum of the average slopes (Pml, Pm2) of each of these faces. . This estimate is based on the assumptions that led to the results presented in Table 2.
- the invention provides transparent substrates which have relief patterns such that the average slope provides a High TLH and a very low Haze, approaching the properties of a float glass, while being aesthetic, the patterns being discrete in size and distributed over the entire surface so as to generate a homogeneous surface appearance.
- the invention also relates to a horticultural greenhouse equipped with at least one substrate such as those described above.
