Description
(1) technical field
The present invention relates to glass field of new materials, in particular to a kind of to be suitble to artificial molding big container glass and its preparation side
Method.
(2) background technique
Glass bottle and jar is most common a kind of daily necessities, can be used as the packing container of food, beverage and many products, using ten
Divide extensive.Round, oval, rectangular and special-shaped bottle etc. can be divided by face shaping；Bottle and big can be divided by bottleneck size
Mouth bottle, the former refers to bottleneck diameter and the biggish glass container of body diameter difference, its usual internal diameter of the bottleneck is less than 30mm, is used to
The product of fluid is contained, and the latter refers to bottleneck diameter and the lesser glass container of body diameter difference, is mainly used to contain half
The product of fluid and solid.In the production technology of container glass, blowing is broadly divided into according to mechanical-moulded mode and pressure blows two
Kind method.
In recent years, with the increasingly raising of people's living standard, the type of glass bottle and jar also gradually increases.Wherein, fruit
The demand of ferment, dinner party beer device and various beverage container to large glass Bottle & Can is also increasing, this kind of large glass Bottle & Can
Volume tend to exceed 15 liters.But this kind of large glass Bottle & Can is in process of production, mainly in molding link, at present
It also cannot achieve continuous mechanization blowing or pressure blow molding, the reason is that: traditional machine when the volume of glass bottle and jar is excessive
Tool molding mode (such as: blowing and pressure are blown) not can guarantee the uniformity of its wall thickness.It is well known that the wall thickness of glass bottle and jar directly closes
It is the ability of the pressure into its mechanical strength and receiving, when the gage distortion of bottle wall, so that bottle wall has weak link, to influence
Shock resistance and internal pressure resistance performance.Compared with mechanical-moulded, artificial the advantages of forming is can to undergo in forming process repeatedly
Blowing operation is easier to the wall thickness and its uniformity of control Bottle & Can.It is well known that the artificial molding time is far more than machine
The tool molding time, this puts forward new requirements to the formula of glass, it may be assumed that and " the material property " of glass metal wants long enough, in other words,
1000Pa.s is generally not to be exceeded in the viscosity change of glass metal in forming temperature scope, in turn, in the viscosity of 1000Pa.s
The forming temperature scope of glass should be big as far as possible in difference.This is closely related with unique moulding process of large scale container glass product,
Since " drop " of glass metal is heavier (generally more than 5 kilograms), in artificial formative stage, the glass metal surface temperature that is contacted with mold
Degree decline is very fast, and the temperature decline inside glass metal is slower, for artificial molding angle, inside glass metal and surface
In the temperature difference range, viscosity change do not answer it is excessive, otherwise surface " hardening " excessive velocities and can not form.Therefore, it designs while full
The glass formula that sufficient physicochemical property and technique require is the key that current artificial molding big container glass.Up to the present, also
Have no the report of this kind of big container glass formula and its technique.
(3) summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of raw material to be easy to get, production cost is low it is suitable manually at
Big container glass of type and preparation method thereof.
The present invention is achieved through the following technical solutions:
One kind being suitble to artificial molding big container glass, it is characterized in that, it is prepared by effective material of following parts by weight:
SiO2 73-78.23 part, Al2O3 1.50-3.36 parts, Na213.28-16.00 parts of O, K20-1.55 parts of O, MgO 1.99-2.66
Part, 0.92-6.00 parts of CaO.
The above-mentioned preferred weight proportion of effective material are as follows:
SiO2 78-78.23 part, Al2O33.00-3.36 parts, Na213.28-14.00 parts of O, K21.50-1.55 parts of O, MgO
2.50-2.66 parts, 0.92-1.00 parts of CaO.
Effective material SiO2Source be quartz sand, Al2O3Source be aluminium hydroxide, Na2The source of O is carbonic acid
Sodium, K2The source of O be potassium carbonate, the source of MgO be magnesia, CaO source be calcium carbonate.
The above-mentioned preparation method for being suitble to artificial molding big container glass, includes the following steps:
(1) accurately weigh the raw material weight of each effective material and be uniformly mixed, batch is made, by batch be placed in kiln in
It melts and is homogenized under 1813-1843K；
(2) glass melt obtained by step (1) temperature after material path flow to work department is down to 1416-1497K；
(3) choose glass metal by blowing bar, and blow out vesicle；
(4) step (3) are repeated several times, wait blow glass metal that bar dips it is enough when, disposably blow advised to finished product greatly in a mold
Lattice；
(5) glassware that step (4) obtains is put into annealing kiln, furnace cooling after annealing at 777-807K.
More excellent technical solution of the invention are as follows:
In step (1), melting temperature of the batch in kiln is 1833-1843K.
In step (2), the temperature of work department is 1468-1497K, and the viscosity of glass metal is 102Pa·s。
In step (3), glass metal is chosen by drying, and blow out the vesicle that wall thickness is 5 ± 0.5mm.
In step (5), glassware is put into annealing kiln, furnace cooling after the 0.5h that anneals at 801-807K.
Big container glass material according to the present invention, glass metal have longer material, forming temperature scope (corresponding glass
The viscosity of glass liquid: 102-105Pas) up to 300K or more, can be avoided because artificial shaping dope speed is slow may occur at
Glass metal surface " hardening " phenomenon during type；Meanwhile glass metal is longer " material property ", is also beneficial to avoid because in glass metal
The generation of " physics striped " caused by the temperature difference on portion and surface.
The present invention has the characteristics that at low cost, raw material are easy to get, together there is no using the expensive or virose raw material of tool
When product have good physical property, vickers microhardness be greater than 500Kg/mm2, it is adapted for artificial molding big Bottle & Can glass
Glass material.
