Description
Technical field
The present invention relates to foamed glass and manufacture method thereof.The foamed glass that specifically is fit to bottle for cosmetics, cosmetic glass, Glass Containers purposes such as (glasswares), this beautiful appearance, foamed glass and manufacture method thereof that transparency is high.
Background technology
The foamed glass that microbubble is rich in glass inside is that everybody quite is familiar with, Japanese kokai publication hei 1-270539 communique for example, and the spy opens flat 2-14848 communique, and the spy opens on the flat 2-14849 communique all announcement.The purpose of these foamed glass all is in order to improve the value of glassy product, and will produce simple, convenient.Specifically be to add the reductibility frit to the frit surface of molten, reaction generates diameter at the left and right sides of 0.5～1.5mm bubble, after adding the reductibility frit, make the oxygen reaction in itself and the atmosphere, reaction times is used for adjusting reducing power, subsequently stirred glass about 0.5～5 minute, the bubble of generation is evenly distributed, and this promptly reduces the foamed glass production method.
In addition, the spy opens on the flat 6-144872 communique and has also showed other foamed glass.The purpose of this kind of foamed glass is in order to improve the outward appearance that the spy opens foamed glass shown in the flat 1-270539 communique.It is formed by three layers, and nexine and skin are not contain bubble, and proportion is at the glass more than 2.0, and the middle layer is to contain the foamed glass that diameter is 0.1～5mm bubble, and proportion is between 1.0～1.5, and the generation of bubble also is to use the reductibility frit.
Foamed glass shown in the Te Kaiping 1-270539 communique, what its reductibility frit used is the reductibility frit of only siliceous (Si), so the bubble diameter that generates is very big, the size of bubble is uneven again, we can say that such foamed glass does not have sight.The influence of oxidated iron when foamed glass is produced in addition, the variable au bleu of glass self lacks transparency.
Foamed glass shown in the Te Kaiping 2-14848 communique, what its reductibility frit used also is the reductibility frit of only siliceous (Si), so the bubble that generates is also very big, does not have sight.Simultaneously self coloring problem when preventing that foamed glass from producing has to add the cerium oxide of high price, so just brings a problem that cost is high.
Foamed glass shown in the Te Kaiping 2-14849 communique, what its reductibility frit used also is the reductibility frit of only siliceous (Si), so the bubble that generates is also very big,
Do not have sight.Meanwhile foamed glass has also added tinting material when producing, and make bubble not of uniform size seem dazzling more on the contrary, and desired color also is difficult to painted success.
More than the disclosed foamed glass production method of each patent gazette, all be after the reductibility frit is put into the frit surface of molten, promptly began to stir after 0.5～5 minute, but such method is difficult to control the diameter of bubble, the foamed glass of being produced is rough.
The foamed glass complex structure that Te Kaiping 6-144872 communique is showed, and need particular manufacturing craft, production efficiency is also extremely low.The reductibility frit also is to use the reductibility frit of only siliceous (Si) in addition, and the bubble of generation is excessive, lacks sight.
Summary of the invention
At the problems referred to above, the present invention has carried out inquiring into energetically and studying, and has createed new method.That is exactly not only to contain the reductibility material in the reductibility frit, more can add whipping agent, and when glass foamed, the diameter of bubble is control easily just like this, can prevent that the bubble size that generates is uneven with diameter control within the limits prescribed.
The objective of the invention is to provide that to have sight good to society, the foamed glass that transparency is good, and the high efficiency production method of this foamed glass is provided.
Foamed glass of the present invention is the foamed glass that frit and the reaction of reductibility frit generate.Wherein the feature of reductibility frit is not only to contain the reductibility material, and contains whipping agent.
The bubble that uses reductibility frit that this kind contains reductibility material and whipping agent to generate is little, and the mean diameter of bubble is in very little scope, and the uneven phenomenon of bubble size is obviously improved.Refraction of light is more even after the illumination, and the sight and the transparency of foamed glass are significantly increased.
The whipping agent that the present invention uses is a compound of selecting one or more in carbonate, supercarbonate, carbonic ether, and the whipping agent of Zu Chenging is comparatively ideal like this.
Contain this kind whipping agent in the reductibility frit, when being subjected to heat foamable, can also control the foaming of reductibility material.As foamed glass integral body, the diameter of bubble is control easily just like this, thereby can significantly improve the sight and the transparency of foamed glass.
The reductibility material that the present invention uses is a material of selecting one or more in silicon (Si), metallic aluminium (Al), metallic zinc (Zn), metallic tin (Sn), carbon (C), and the reductibility material of Zu Chenging is comparatively ideal like this.
These reductibility materials have special reductibility to frit, only need to add to generate the uniform bubble of diameter on a small quantity.
Foamed glass of the present invention, the mean diameter of the bubble that it contains should be controlled in 0.01～0.5mm scope, the little and even sight and the transparency that could improve foamed glass of bubble diameter.
To be controlled in 100: 01～100: 5 (calculating with weight %) scopes be comparatively ideal to the reactive ratio of frit and reductibility frit among the present invention.
The reactive ratio of frit and reductibility frit is controlled in this scope, just can make the bubble size of generation even, and the refraction of light also evenly causes like this, improves the sight and the transparency of foamed glass.
Can also add tinting material in the foamed glass of the present invention.
Add the color that tinting material can further improve foamed glass, improve the ornamental of foamed glass.When foamed glass of the present invention did not contain tinting material, sight and transparency were all good, and the adding tinting material is easier to obtain desired color.
Tinting material can be added in the frit, also can be added in the reductibility frit, all can obtain good additive effect.

Embodiment
Below be elaborated with regard to foamed glass of the present invention and manufacture method thereof.
[the 1st embodiment]
The 1st embodiment is meant that frit and reductibility frit react the foamed glass that generates bubble and form.Wherein not only contain the reductibility material in the reductibility frit, and contain whipping agent, both are used in combination to be heated and can produce bubble.The foam characteristics of whipping agent is that bubble is small, and can influence the foaming of reductibility material, and the diameter of bubble integral body can be controlled in the small range, prevents that the bubble diameter size from having big difference, thereby can significantly improve the sight and the transparency of foamed glass.
Below elaborate with regard to reaction raw materials and the reaction conditions of the 1st embodiment.
(1) frit
Frit be meant can with the reductibility frit generation reduction reaction that contains the reductibility material, generate the frit of bubble.
Such frit can be from SiO
2, Na
2O, K
2O, CaO, MgO, BaO, B
2O
3, Al
2O
3, LiO
2, CeO
2Deng several compositions of selection in the oxide compound.
Before adding the reductibility frit, the high temperature of using 1000～1500 ℃ heats frit, and it is aqueous that frit is fused into, so just can uniformity with the reduction reaction of reductibility frit.
(2) reductibility frit
Contain reductibility material and whipping agent in the reductibility frit that uses during the 1st embodiment,
The bubble that this kind reductibility frit generates, it is little that diameter differs, and mean diameter is more consistent, thereby can improve the sight and the transparency of foamed glass.
The reductibility material that contains in the reductibility frit can select then one or more material composition in silicon (Si), metallic aluminium (Al), metallic zinc (Zn), metallic tin (Sn), carbon (C).Wherein the reductibility of silicon (Si) is good especially, and a small amount of interpolation can even foaming, the first-selected object that is to use.
When the content of reductibility material, the gross weight of reductibility frit calculated with 100 weight %, it was comparatively ideal being controlled in 0.1～20 weight % scope.
Its reason is that the content of reductibility material is lower than 0.1 weight %, is difficult for foaming, no additive effect.And the content of reductibility material is when being higher than 20 weight %, and the bubble of generation is too big and be difficult to control.
Each side factors such as comprehensive foaminess and the control of bubble size, the content of reductibility material is controlled in 0.3～15 weight % scope even more ideally in the reductibility frit, and to be controlled in 0.5～10 weight % scope be optimal then (reductibility frit gross weight is calculated with 100 weight %).
The whipping agent that contains in the reductibility frit can select one or more compound to form in carbonate, supercarbonate, carbonic ether.Concrete carbonate, supercarbonate, carbonic ether have: lime carbonate (CaCO
3), yellow soda ash (Na
2CO
3), volatile salt ((NH
4)
2CO
3), salt of wormwood (K
2CO
3), lead carbonate (PbCO
3), zinc carbonate (ZnCO
3), Strontium carbonate powder (SrCO
3), iron carbonate (FeCO
3), copper carbonate (Cu
2CO
3), nickelous carbonate (NiCO
3), barium carbonate (BaCO
3), magnesiumcarbonate (MgCO
3), manganous carbonate (MnCO
3), Quilonum Retard (Li
2CO
3), sodium bicarbonate (NaHCO
3), saleratus (KHCO
3), carbonic acid methyl ester ((CH
3) (C
2H
5) CO
3), carbonic acid dimethyl ((CH
3)
2CO
3), carbonic acid diethyl ((C
2H
5)
2CO
3) etc., can therefrom select one or more compound to form.
Consider and be convenient to the control foaming, selecting decomposition temperature during selection is comparatively ideal at the compound more than 500 ℃.Select decomposition temperature then even more ideal at the compound more than 800 ℃.
Comprehensively it seems lime carbonate (CaCO
3), barium carbonate (BaCO
3) use with silicon reductibility combinations of materials such as (Si), the size of bubble, uniformity coefficient all can be controlled well, are the ideal whipping agents.
The gross weight of reductibility frit is calculated with 100 weight %, and it is comparatively ideal that the content of whipping agent is controlled in 0.1～30 weight % scope.
Its reason is that the content of whipping agent is lower than 0.1 weight %, and whipping agent is difficult to control the foaminess of reductibility material, and the content of whipping agent can make bubble become too big when being higher than 30 weight % on the contrary, is difficult to control.
Each side combined factors such as control from foaminess and bubble size, the content of whipping agent is controlled in 0.5～25 weight % scope desirablely more in the reductibility frit, and to be controlled in 1.0～20 weight % scopes be optimal then (reductibility frit gross weight is calculated with 100 weight %).
During the content of the whipping agent that constitutes by carbonate etc. in decision, also should be taken into account the content of reductibility material.Concrete method is: when the content of reductibility material was 100 weight unit, the content of whipping agent can be controlled in 1～1000 weight unit scope.Its reason is the content of whipping agent when being lower than 1 weight unit, is difficult to control the foaminess of reductibility material.And the content of whipping agent is when being higher than 1000 weight unit, and bubble becomes too big conversely, and foaming is difficult to control.
Except reductibility material and whipping agent, can also add some glass ingredients in the reductibility frit,, pulverize again after the cooling, be crushed to mean diameter in 0.5～20mm scope these raw material fusions.
The glass composition can use the raw material identical with above-mentioned frit, also can use the fusing point raw material lower than above-mentioned frit.For example use the frit of 500 ℃ of fusing point less thaies, it is convenient that low-melting frit mixes with reductibility material and whipping agent, put in the frit of molten as the reductibility frit after, also easy with the fusion of frit.
Certainly, not necessarily leave no choice but add the glass composition, fuse again, cool off, pulverize.Also can mix reductibility material, whipping agent, glass ingredient three, add some tackiness agents again and make little round bead shape, this method also is good.Reductibility frit of the present invention also comprises the reductibility frit of this shape.
(3) reaction conditions
1. reaction is compared
Reaction between frit and the reductibility frit is than there is no particular restriction.In general, in the frit of per 100 weight unit, it is comparatively ideal that the addition of reductibility frit is controlled in 0.3～7 weight unit scope.Its reason is that the reaction ratio of reductibility frit is lower than 0.3 weight unit blow weak.And the reaction of reductibility frit ratio is when being higher than 7 weight unit, and bubble becomes too big conversely, and foaming is difficult to control.
In general, in the frit of per 100 weight unit, the addition of reductibility frit is controlled in 0.5～6 weight unit scope desirable more, and 1～5 weight unit scope that is controlled at then is ideal.
2. temperature of reaction
The temperature of reaction of frit and reductibility frit, it is comparatively ideal being controlled in 1000～1500 ℃ of scopes.Its reason is that temperature of reaction is lower than 1000 ℃ of blow weaks, and when temperature of reaction was higher than 1500 ℃, it is too big that bubble becomes, and foaming is difficult to control.
In general, the temperature of reaction of frit and reductibility frit is controlled in 1100～1400 ℃ of scopes desirable more, and it then is optimal being controlled in 1150～1350 ℃ of scopes.
Temperature of reaction is consistent with the melting temperature (Tm) of frit.
3. react style
There is no particular restriction for the reaction style of frit and reductibility frit.Can be the successive reaction style, also can be to be interrupted the reaction style, can also be both composite reaction styles.The successive reaction style makes the frit of molten continue to flow out, and the reductibility frit drops into continuously, and constantly reaction generates foamed glass.Be interrupted the reaction style, add a certain amount of reductibility frit in the frit of molten in crucible, reaction generates foamed glass.
No matter be continous way or discontinuous, all to react while stirring.Just do like this and the mean diameter of bubble can be controlled in the specialized range, the distribution of bubble also relatively evenly.
The foamed glass that reaction generates can be made different shape according to purposes, as vial, sheet glass, Glass Containers or the like.
4. bubble
Bubble in the foamed glass, there is no particular restriction for its mean diameter.In general be controlled in 0.01～2mm scope better.From improving ornamental angle, can further be controlled in 0.01～0.5 scope (not containing 0.5mm).Its reason be the mean diameter of bubble less than 0.01mm, the difficulty that is shaped, and skewness.And the mean diameter of bubble is during greater than 0.5mm, and the sight of foamed glass and surface smoothing all will be affected.
In general, the bubble in the foamed glass, its mean diameter is controlled in 0.1～0.4mm scope desirable more, and being controlled at then is optimal in 0.2～0.3mm scope.
[the 2nd embodiment]
The 2nd embodiment is meant that frit and the reaction of reductibility frit generate the manufacture method of foamed glass.It comprises three operations: the fusion operation of frit, the input operation of reductibility frit, bubble are regulated operation.
Such with reductibility frit reaction generation bubble glass, not only use the reductibility material, and use whipping agent.Thereby the bubble diameter that generates is little, and control is convenient, and the bubble diameter size is even, and sight and transparency are all good, the production efficiency height.
Following with reference to Fig. 1, specify with regard to the manufacture method of the 2nd embodiment.Wherein frit and reductibility frit etc. have been described in the 1st embodiment, have here just omitted.
(1) the fusion operation of frit
The fusion operation of frit is exactly SiO
2, Na
2Frits such as O heating fusion makes it become the operation of glass solution.This fusion operation is carried out at calciner 10 places of Fig. 1.Concrete method is that calciner 10 tops have dog-house 13, and frit 16 drops into from dog-house 13, heater via 14 heating, and the reductibility frit that fuses into uniform glass metal 18, the second operations adds in this glass metal 18.
Also have, the front illustrated that the melting temperature (Tm) of glass metal 18 (frit 16) can be regulated with well heater 14, and being controlled in 1000～1500 scopes is ideal.
(2) the input operation of reductibility frit
The input operation of reductibility frit is exactly the reductibility frit of being made up of lime carbonate, silicon, low melting glass 36, puts into molten, is in this example in the glass metal 19 of flow state to go.This drops into operation and carries out at supply channel 22 places of Fig. 1.Concrete method is that the top of supply channel 22 has measuring apparatus 32, and reductibility frit 36 is dropped into from dog-house 34, enters when stressing in the measuring apparatus 32, regulates the addition of reductibility frit 36.The addition of reductibility frit 36 is described in the 1st embodiment, and the frit 16 of promptly per 100 weight unit adds the reductibility frit 36 of 0.3～7 weight unit.
The addition of reductibility frit 36 is to calculate according to the amount of frit 16.In the example that the 2nd embodiment is lifted, the addition of reductibility frit 36 is that the flow according to solution shape frit calculates.Flow specifically is controlled at 1～20cm
3Better, flow control is in this scope in the/minute scope, and the reaction of reductibility frit 36 and frit 16 (glass metal 19) just can be really, carry out fully, and the foamed glass integral production is also good.
Reductibility frit 36 after the metering falls from blanking port 30, arrives the surface 17 of glass metal 19 through inclined-plane thrust-augmenting nozzle 23.Reductibility frit 36 is along with glass metal 19 prints the diffluence of A direction to arrow, and the heat self of heat absorbing glass liquid 19 begins fusion simultaneously.The reductibility frit 36 initial positions that arrive are D lines, that is to say that near the D line, reductibility frit 36 is also keeping original diameter, are after this fused gradually, and diameter is also just more and more littler.
In the example that the 2nd embodiment is lifted, vibrating device 24 also is equipped with in the below of inclined-plane thrust-augmenting nozzle 23.Reductibility frit 36 is vibrated by inclined-plane thrust-augmenting nozzle 23 time, and dispersion is just more even like this, and foaming is also just more even, and the control of bubble mean diameter also just is more prone to.
(3) bubble is regulated operation
It is exactly that stir on the limit that bubble is regulated operation, and the operation of the mean diameter of bubble is regulated on the limit.Bubble is regulated operation and is carried out with agitator 38.Reductibility frit 36 is along with glass metal 19 goes to arrow seal A direction, and both react (foaming and reduction) simultaneously, and when arriving agitator 38, reaction also is not very even.But by the stirring of agitator 38, reaction just can be carried out fully, and the mean diameter of bubble is controlled, and it is even that the size of bubble just becomes.By the stirring of agitator 38, it is comparatively ideal being controlled at the mean diameter of bubble in 0.01～0.5mm (not containing 0.5mm) scope.
After reductibility frit input, regulate operation to bubble and begin, the middle time that needs at least more than 10 minutes, it is desirable to 15～60 minutes more.Its reason is to be lower than 10 minutes the elapsed time, and the mean diameter of bubble is still very big sometimes.And elapsed time when surpassing 60 minutes, reductibility frit 36 and glass metal 19 (frit 16) overreact, after this when bubble is regulated operation, the adjusting of the mean diameter of the bubble difficulty that will become.
(4) molding procedure
After stirring by agitator 38, the glass metal 19 (being referred to as gob sometimes) that contains bubble flows out along arrow seal B direction, enters molding procedure (not showing among Fig. 1).By using mould, foamed glass can be made needed different shape in molding procedure.
