Abstract
The invention relates to a Nd2O3-containing glass flux, which is prepared from the following raw materials by weight: 2-2.5 parts of cerium nitrate, a proper amount of distilled water, 2-3 parts of Nd2O3, 6-7 parts of magnesium hydroxide, 2-3 parts of sodium bicarbonate, 40-45 parts of bismuth oxide, 4-5 parts of boron oxide, 1.5-2 parts of silica sol, and a proper amount of ammonia water. According to the present invention, the flux is suitable for float glass production and has an excellent fluxing effect, and the melting temperature is effectively reduced with the flux compared with the single use of sodium oxide so as to save the energy source; Nd2O3 and magnesium hydroxide are used so as to provide a clarifying effect and enhance the strength and the ultraviolet ray filtration performance of the glass; and with the process, the nano-scale cerium oxide is wrapped on the particle surface so as to rapidly and completely eliminate the gas seeds.
Description
Technical field
The present invention relates to glass manufacturing area, particularly relate to a kind of containing Nd

Background technology
Float glass is a kind of method that sheet glass is produced, in the production of float glass, there is a very important link to be put into continuously in the middle of melting furnaces by batch charger by admixtion to melt, formed even, pure, transparent through heat and meet forming requirements, the process of continuous in glass, single liquid phase, be one of main phase in glass manufacturing process, found speed and the reasonableness of founding and the Yield and quality of glass, qualification rate, production cost, fuel consumption and tank furnace life-span etc. are had a significant impact.The melting process of glass comprises 5 stages, i.e. the formation of the formation of silicate, glass, the clarification of glass, the homogenizing of glass and cooling.
In order to improve the quality of float glass, its temperature of fusion is improved constantly, and the temperature of current float glass smelting kiln flame space, up to 1580 DEG C, is generally Na for the composition of fluxing
2o, generally has soda ash to introduce, Na
2o has wide material sources, lower-cost feature as float glass fusing assistant, but it is limited to there is fluxing capabilities, and sodium ion easily migrates to glass surface, and glass can be made to produce the phenomenon of " mouldy ".
Also fluorite is usually adopted to introduce fluorochemical as fusing assistant in prior art.When using fluorite, in kiln, glass melting process is a pyroreaction, uses the glass metal containing fluorine element can cause Eroded to kiln pool wall, reduces the work-ing life of kiln and the security of production.And a large amount of fluorochemicals produced in process of production in air, cause topsoil with fume emission.
Therefore need to improve fusing assistant, to improve the performance of glass, save energy, extend the work-ing life of melting furnaces, protection of the environment.
Summary of the invention
The object of the present invention is to provide a kind of containing Nd
