Description
Technical field
The present invention relates to a kind of preparation method of green non-poisonous glass fining agent, belong to fining agent preparing technical field.
Background technology
Glass releases substantial amounts of gas in melting process, because various mineral (such as feldspar) in frit,
Metal salt (such as barium carbonate), oxide (such as SiO2) the released reaction product of chemical reaction such as decompose, melt, they are
Inevitable outcome in Improving Glass Manufacturing Processes, while being to be free in the unnecessary reaction product outside glass structures again, is referred to as
Formation of gaseous inclusions, commonly referred to as " bubble ", the presence of these bubbles can all produce fatal shadow to final finished glass article
Ring.According to different glass compositions and production technology, the characteristics of bubble in glass has chemical diversity and polymorphic structure.According to
, there are dissolving bubble, chemical bond bubble in the generation source of bubble, it is seen that bubble, bath surface bubble, closed air bubbles etc.；According to
The chemical composition of bubble, there is CO2、O2、H2O、H2、SO2、N2Deng；According to the form of bubble, air pocket (diameter ＞ can be divided into
0.1mm), middle bubble (0.10~0.01mm of diameter), minute bubbles (diameter ＜ 0.01mm).It is well known that in Improving Glass Manufacturing Processes
In, the decomposition of silicate is that now glass is not yet formed at about 800~1000 DEG C, and all kinds of formation of gaseous inclusions of generation pass through each
The interface void of solid phase fully enters flue and discharged.As temperature is increased to 1200 DEG C~1300 DEG C, the various of glass are constituted
Material surface is initially formed the larger high viscosity liquid phase substance of layer of surface tension force, and all kinds of formation of gaseous inclusions now decomposited are just
It is possible to closing and forms bubble in the melt, these bubbles is possible to gram only when its partial pressure in the melt is sufficiently large
Take the resistance of bath surface and escape, temperature continues to be increased to 1300 DEG C~1600 DEG C, and frit all melts, semifluid shape
Glass melt wrap up substantial amounts of bubble, at this moment, the interfacial tension of vapor-liquid two phases is in a kind of relative balance state in glass,
There is no the bubble wrapped up in the interference of external force and destruction, vitreum just to remain in all the time in glass metal.Discharged by External force interference
The process of bubble is clarifying process in glass metal.
Fining agent can be divided into according to clarification mechanism by oxide fining agent, sulfate fining agent, halide fining agent
With the major class of compound clarifier four, conventional fining agent has white arsenic (arsenic trioxide), antimony oxide, nitrate, sulfate, fluorination
Thing, rare earth compound and complex composition etc., wherein white arsenic are the fabulous fining agents of clarifying effect, and glass industry is commonly called as " clarification
King ", the clarification of antimony oxide is similar to white arsenic, and clarifying effect is also preferable, but with safety in production and the requirement of environmental protection,
Arsenic, antimony class fining agent with severe toxicity have been prohibited from using, and white arsenic clarification is even above with preferable clarifying effect to develop
The fining agent of effect, people have carried out numerous studies to compound clarifier, also disclose that some have answering for preferable clarifying effect
Fining agent is closed, but because the chemical clarification that fining agent is carried out to glass is real by adding oxidant and multivalent oxide
It is existing, the contradiction between sulphur clarification and oxygen clarification is easily caused, causes SO in glass2、O2The disorder of solubility gradients, so that glass
There is microvesicle in plate face, causes the flaw of glass.
The content of the invention
The technical problems to be solved by the invention are：Pollution is also easy to produce under the high temperature conditions with fining agent for traditional glass
Property gas, cause severe operational environment, there is provided a kind of composite granule and electricity voluntarily to prepare the problem of pollution environment

Alcoholic solution, is then added dropwise boric acid solution, forms gel precipitate, after drying with powdered rice hulls mixed calcining, and black powder is made,
Again under nitrogen guard mode, composite granule of the reaction generation containing carborundum, boron carbide and silica, finally by composite powder
Body and calcium carbide ball milling mixing, produce green non-poisonous glass fining agent.During the present invention in glass using making, composite granule
In boron carbide and calcium carbide in calcium carbide made with glass during the oxygen and steam reaction that produce, generate carbon dioxide
Deng gas, coordinate the boron oxide of generation to volatilize at high temperature, minute bubbles is discharged rapidly after growing up, in later stage cooling procedure,
The calcium oxide of generation can absorb the carbon dioxide in bubble, reaches the effect of clarification, and calcium oxide can also effectively improve glass
Chemical stability and mechanical strength, the problem of efficiently solving during traditional glass fining agent use easily pollution environment.

Under, 30~50mL mass fractions are added dropwise into three-necked flask by dropping funel for 4~6% boric acid solutions, control 15~
Dripped off in 20min, treat completion of dropping, continue 45~60min of constant temperature stirring reaction；
(3) after above-mentioned stirring reaction terminates, by material filtering in above-mentioned three-necked flask, filter cake is collected, and filter cake is put
In baking oven, drying is placed in mortar to constant weight, then by dried filter cake under the conditions of temperature is 105~110 DEG C, grinding 10
~15min, obtains filter cake powder, standby；
(4) 200~300g rice husks are weighed, are placed in baking oven, are dried under the conditions of temperature is 105~110 DEG C to constant weight, then
Dried rice husk is poured into pulverizer, 120~180 mesh sieves are crossed after crushing, powdered rice hulls are obtained；
(5) it is 1 in mass ratio:1~1:3 pour into the standby filter cake powder of step (3) and above-mentioned gained powdered rice hulls in beaker,
After 20~30min of glass bar stirring mixing, material in beaker is transferred to Muffle furnace, forged under the conditions of temperature is 500~550 DEG C
45~90min is burnt, room temperature is cooled to the furnace, obtains black powder；
(6) above-mentioned gained black powder is transferred to retort, nitrogen is passed through into stove with 20~30mL/min speed, in nitrogen
Under gas shielded state, 1200~1300 DEG C, 2~4h of insulation reaction, furnace cooling are warming up to 10~20 DEG C/min rate programs
To room temperature, discharging obtains composite granule；
(7) count by weight, 60~80 parts of above-mentioned gained composite powders, 20~30 parts of electricity are sequentially added in ball mill
Stone, is 10 by ball material mass ratio:1~20:1 adds after zirconium oxide ball milling pearl, 24~36h of ball-milling treatment, crosses 325~500 mesh sieves,
Produce green non-poisonous glass fining agent.
The application process of the present invention：In the glass smelting high temperature period, green non-poisonous glass prepared by the present invention is clarified
Agent be added to glass smelting batch in, the amount of addition is found Glass Batch Quality 0.2~0.6%, and in temperature be 1300
180~200min of high temperature melting is carried out at~1600 DEG C, after end is founded, glass metal is obtained.After testing, present invention system is utilized
