When 550ppm, the ratio R edox of ferrous ion quality and whole iron ion quality is 25~35%.
The each component effect in glass of the present invention is illustrated below：
SiO2It is the main body of the network structure of glass, chemical stability, thermal stability, the mechanical strength of glass can be improved
Deng.If content is less than 59.0%, the more difficult forming of glass, and has crystallization tendency, while chemistry-resistant characteristic can reduce.But
SiO2More infusibilized substance, content is more than 70.0%, glass melting temperature and clarifying temp can higher, and in viscosity
It rises, glass is made to be difficult to homogenize, discomfort shares floating process manufacture.Therefore, SiO of the invention2Content range is needed 59.0
~70.0%.
Al2O3The crystallization tendency that glass can be reduced, improves chemical stability, thermal stability, mechanical strength, the hardness of glass,
It is also the neccessary composition of raising glass modulus, but if Al2O3Glass viscosity can excessively be increased, crystallization is easy and is precipitated, it is difficult
To be shaped to glass plate with float glass process, overflow downdraw etc..Al in alumina silicate glass3+Tend to form aluminum-oxygen tetrahedron network
[AlO4], than Gui Yangsimianti [SiO4]Cyberspace is much greater, the cyberspace of bigger make ion exchange be more easy into
Row, therefore Al high in glass2O3Content can promote ion exchange, contribute to ion in lower temperature and under the shorter time
It swaps.Therefore, on the one hand, Al2O3Content is more than 23.0%, will increase the crystallization tendency of glass and increases high temperature viscosity,
Make glass be difficult to melt, in turn, so that the softening point temperature of glass is improved, increase the hot processing temperature of glass；On the other hand, Al2O3
When content is very few, it is unable to give full play the ion-exchange performance of glass.Therefore, Al in the present invention2O3Content range be 13~
23%, preferably 13~18%, more preferable 13.5~17.5%.
If SiO2And A12O3Total content SiO2+A12O3More than 83%, then glass viscosity at high temperature can increase, and make glass
Glass melting is difficult to carry out.Therefore, SiO of the invention2+A12O3Total content be up to 83%.If SiO2+A12O3Total content it is few
In 70%, then the resistance to fragility of glass can reduce.Therefore, SiO of the invention2+A12O3Total content be at least 73%.
Li2O is ion exchange ingredient, and can make the reduction of glass high temperature viscosity, improves meltbility, the mouldability of glass.
Li2Although O is maximum to improving the effect of glass compaction stress value in alkali metal oxide, containing 5% or more Na2O's
In glass, if Li2The content of O is more, then has the tendency that reducing compression stress value instead.In addition, if Li2The content of O is excessive,
Then glass is easy devitrification, and the coefficient of expansion becomes excessively high, and thermal shock resistance reduces.In addition, Li2The content of O is excessive, glass it is low
Warm viscosity reduces excessively, this easily causes stress mitigation, instead reduces the compression stress value of glass.Therefore, in the present invention
Li2O content is not essential, and content range is 0~4%.
Na2O is for forming surface compression stressor layers by ion exchange and the group for improving glass melting property
Point, in addition, Na2O is the neccessary composition for improving glass devitrification again.If Na2The content of O is less than 5%, then the meltbility drop of glass
It is low, and be difficult that required surface compression stressor layers are formed by ion exchange.In the present invention, Na2The content of O is at least 5%.
If Na2O content is excessive, then the coefficient of thermal expansion of glass is excessively high, and thermal shock resistance reduces, and strain point reduces, and chemically-resistant is not invaded
Erosion, weatherability also reduce.Therefore Na2The content of O is up to 15%.
K2O is for improving glass melting and for improving ion exchange ratio in chemical strengthening to obtain required surface
The component of compression stress and stress layer depth still improves the ingredient of devitrification resistance.It should be noted that as added in glass
K2O, then its lower range is 1% or more, and otherwise the ion exchange ratio of chemically enhancing glass improves ineffective.If K2O's contains
Amount is excessive, then coefficient of thermal expansion becomes excessively high, and thermal shock resistance reduces, and strain point reduces, therefore preferably 7% or less.Cause
This, in the present invention, K2The content of O is 1~7%, it is preferable that K2The content of O is 1.5~7%.
Li2O+Na2O+K2O is the ingredient of ion exchange in sillico aluminate glass, or reduces glass high temperature viscosity, carries
The ingredient of high glass melting and mouldability, Li2O+Na2O+K2When O is excessive, glass is easy devitrification.In addition, coefficient of thermal expansion carries
Exceed more, thermal shock resistance reduction, it is difficult to the matched coefficients of thermal expansion with periphery material.In addition, strain point reduces excessively, it is difficult to
Compression stress after raising chemical strengthening.On the other hand, Li2O+Na2O+K2When O is very few, the meltbility of ion-exchange performance or glass
It reduces.Therefore, Li2O+Na2O+K2The total amount of O is 8~25wt%, it is preferable that Li2O+Na2O+K2The total amount of O be 10~
20wt%.
CaO can make Gui Yangsimianti [SiO4]It is formed by network structure relaxation, fracture, although glass can be improved in height
The lower melting property of temperature makes glass be easy to be molded, and still, the introducing of CaO can the seriously ion-exchange performance of obstruction glass and shadow
Its chemical strengthening performance is rung, thus, it can at most contain 0.1%, preferably not introduced additionally as active ingredient.
MgO is glass network modifier oxides, when the content of MgO is not more than 7.0%, contributes to the high temperature for reducing glass
Viscosity and the meltbility for improving glass improve uniformity, increase hydrolytic resistance.MgO can also make glass tend towards stability, and improve glass
Durability, prevent glass from generating crystallization, inhibit the movement of alkali metal ion in glass, it is also the same have improve glass springform
The function of amount.But if content of MgO is excessive, such as > 7%, then the density of glass is got higher with coefficient of thermal expansion, and glass is lost
Saturating tendency, therefore its content range is 1.0~7.0%, preferably 2.5~6.5%, most preferably 3.0~6.0%.
ZrO2The ion-exchange performance that alumina silicate glass can be significantly improved, the surface compression to increase glass are answered
Power, while the strain point of glass can be improved.But if ZrO2Content is excessive, it is possible to so that glass density is become excessively high, resistance to mistake
Permeability reduces.In addition ZrO2It is likely to remain in glass and is used as particle rubble, reduce the crush resistance of glass.It should be noted that
Want to improve ion-exchange performance, ZrO2Content be at least 0.2% or more.Therefore, ZrO of the invention2Content range is 0.2
~2wt%, it is preferable that ZrO2Content is 0.5~1.5%.
B2O3The high temperature viscosity and density of glass can be reduced, while improving the devitrification resistance of glass.But if B2O3
Too high levels can be such that the water resistance of glass reduces.When manufacturing plate glass, in the melting of glass, clarification and forming process,
B2O3It is volatile, to which the homogenieity and flatness of glass plate can be influenced.In addition, the boron oxide in glass can form fine and close boron
Oxygen Si Mianti [BO4]Network keeps stressor layers thinning, and the compression for reducing glass is answered to limit the migration of ion in glass
Force value.Therefore, B2O3Content be 0~4.5%, it is preferable that do not contain B2O3。
The sillico aluminate glass Fe of the present invention2O3Content is 150ppm~550ppm, if iron oxide content total in glass
Less than 150ppm, the heat transfer efficiency of glass metal can be reduced, heat conductivility of glass during following process is influenced, significantly increases
Add production cost.If total iron oxide content is higher than 550ppm, the transmitance of glass can be influenced, influences it as glass cover-plate
Quality when use and beauty.
In addition, total iron Fe in sillico aluminate glass2O3Simultaneously with FeO and Fe2O3Form exists, and divalent state iron is in wavelength
Nearby there is 1000nm stronger absorption peak, three valence state iron to have absorption peak, and the absorption of divalent state iron near wavelength 380nm
Coefficient is usually 7 times or more of three valence state iron, therefore improves the divalent state iron of glass, is more conducive to the heat transfer of glass and is heated.
In addition, the present invention also needs to utilize Fe2O3O is decomposed to give off under high temperature2To eliminate the bubble in glass, (iron oxide pyrolytic is anti-
It answers：Fe2O3→FeO+O2↑)。
Therefore, in the present invention, when total iron is (with Fe2O3Indicate) be 150ppm~300ppm when, ferrous ion quality with
The ratio R edox of whole iron ion quality is 35~45%；If Redox is less than 35%, ferrous ion content is too low, unfavorable
In the heat conduction of glass metal, if being higher than 45%, Fe2O3Content is relatively low, the O of decomposition2Amount is few, and the bubble in glass is eliminated tired
It is difficult；When total iron is (with Fe2O3Indicate) when being 300ppm~550ppm, the ratio of ferrous ion quality and whole iron ion quality
Redox is 25~35%, since total iron is (with Fe2O3Indicating) for content with respect to improving, Redox can be reduced to 25-35%.
The sillico aluminate glass of the present invention, component includes the Fe of 150ppm~550ppm2O3, and Fe2O3For 150ppm
When~300ppm, the ratio R edox of ferrous ion quality and whole iron ion quality is 35~45%；Fe2O3For 300ppm~
When 550ppm, the ratio R edox of ferrous ion quality and whole iron ion quality is 25~35%, is ensureing that glass is good in this way
While the transmitance got well, the heat transfer efficiency of glass metal in kiln can be improved, the clarification of glass metal is made to become simple.
