Description
Technical field
The present invention relates to very white rolled glass production field, particularly relate to a kind of solar energy ultra-white method for glass preparation and goods thereof..
Background technology
Along with the development of photovoltaic electric technology, need to use the high ultra-clear glasses of transmittance as substrate material.Most people thinks that the total iron content of ultra-clear glasses mainly in glass reaches below 200ppm and just can be referred to as ultra-clear glasses, but the raw material of glass production and production process cause wherein must containing a certain amount of iron and sulphur, and the combination of sulphur and iron can make glass from the yellow-green colour occurring during viewed edge not wishing to obtain due to the formation of iron sulfide (being often referred to iron sulphide or many iron sulphide) in glass.
CN200810241740.9 discloses a kind of ultra-white float glass, comprise Base Glass Portion and colorant potion, tinting material consist of ferric oxide, cobalt oxide, Neodymium trioxide, manganese oxide and lanthanum trioxide, the glass edge made is light blue, but final glass whiteness and transmittance are still not high.
Very white rolled glass, refer to the ultra-white photovoltaic glass with a kind of surface that rolling process is produced with floral designs, its pattern structure formula is extruded by two rollers by special grain roller and obtains in melten glass liquid drawing process, this decorative pattern process reduces reflectivity and the specific absorption of light to a certain extent, improves glass transmission rate.
The important means that effectively can increase glass transmission rate reduces the iron level in glass, but it is more difficult on the one hand iron level to be reduced to lower value, and iron level can cause glass to be difficult to clarification after reducing on the other hand.
One of glass quality aspect important factor is exactly the bubble contained in glass, glass is by after being mixed by the raw materials such as silica sand, soda ash, Wingdale, at high temperature melt, glass after high temperature melting is a kind of full-bodied liquid, wherein include a large amount of bubbles, when not using any finings, in bubble, the content of carbonic acid gas, nitrogen is maximum, and they can not be melted in melten glass liquid, if break release after single dependence bubble rises to metal level, that consumes a large amount of time by needing, and does not meet the requirement of suitability for industrialized production.
In the past, in order to reduce the bubble in glass, utilize arsenic to be incorporated in glass batch as a kind of finings, but arsenic at high temperature partly can volatilize and causes environmental pollution, and arsenic is as a kind of highly toxic substance, is difficult to manage.
CN200710054549.9 provides a kind of solar energy very white rolled glass components, based on ordinary flat ultra-clear glasses composition, add the oxides lanthanum of rare earth element, oxidation bait and cerium oxide, but should from final glassy product, its section whiteness and glass transmission rate all have much room for improvement.
