Description
Technical field
The present invention relates to glass production manufacturing technology fields more particularly to a kind of single-sheet fire-resistant glass and preparation method thereof.
Background technique
Flame resistant glass type is more currently on the market, and product quality is irregular, according to China's national standard " peace for building
Full glass flame resistant glass " (GB16763.1-2001) definition and classification, flame resistant glass is divided into single-sheet fire-resistant glass and compound anti-
Flint glass.Single-sheet fire-resistant glass is made of single-glass, and meets the special glass of associated refractory class requirement.Composite fire-proof glass
Glass is combined by 2 layers or 2 layers or more glass or is combined by 1 layer of glass and organic material, and meets associated refractory grade
It is required that special glass.In recent years, most domestic producer starts to lay particular emphasis on the production of single-sheet fire-resistant glass (wherein mainly with caesium
Based on potassium class flame resistant glass), not big breakthrough in terms of the production of composite fireproof glass, market still with grouting-type flame resistant glass and
Based on the composite fireproof glass of part.Composite fireproof glass is more complicated compared with single-sheet fire-resistant glass manufacturing process, in use also more
It is also easy to produce defect, the caesium potassium flame resistant glass in single-sheet fire-resistant glass is to carry out ion exchange to glass by high-temperature molten metal salt
After carry out it is physical toughened processing obtain, the manufacturing cycle is also longer and since it is using normal silicate glass, subsequent
There are certain self-destructions during use.Monolithic borosilicate flame resistant glass is a kind of by changing glass ingredient, glass being effectively reduced
The coefficient of expansion of glass itself effectively improves glass itself softening point temperature, effectively improves the capacity of heat transmission of glass itself, to reach
It is the development trend of the following flame resistant glass to the completely new flame resistant glass of fire prevention purpose.
Traditional glass batch be all by various raw materials through screening, weigh, mix, in the form of bulk powder
Enter kiln, there are many disadvantages for this mode: powdery bulk cargo easily disperses, blocks regenerative chamber, corrodes kiln body；Bulk density is low, feeds intake
It is mingled with a certain amount of air in the process, thermal coefficient is low, and flame is low to the heating efficiency of batch, glass melting, settling time
It is longer, particularly with boracic raw material, the volatilization of boron is also easy to produce when heated, document report boron in glass melting process volatilizees
Occur mainly in front of 1000 DEG C, glass will finally be made to generate the uneven defects of structures such as split-phase, peeling, thus should make rapidly its into
Enter glass structure network and is fixed against.It is a kind of method that boron volatilization is effectively reduced that closely knit material, which is made, in batch, and can
Accelerate being melted for glass.
Since the preparation process of composite fireproof glass is more complex, manufacturing cycle is longer, and deposits in the use process in later period
In certain defect, and the caesium potassium class flame resistant glass in single-sheet fire-resistant glass is that normal silicate glass is exchanged by chemical ion
Carry out again afterwards it is physical toughened be made, preparation process is comparatively laborious, and there are certain self-destruction, borosilicates in the use process in later period
The volatilization of flame resistant glass powdery batch boron during fusing is serious, and especially before 1200 DEG C, this will cause raw material
Added cost, glass properties decline.
For this purpose, designing a kind of single-sheet fire-resistant glass and preparation method thereof, problem above is solved.
