[0085] Specifically, the first embodiment of the brown glass of the present invention, the main raw material formula of the brown glass is as follows in parts by mass:

[0086] Quartz sand 150~250

[0087] Soda ash 35~60

[0088] Calcite 40~70

[0089] Glauber's salt 1.5~5

[0090] Iron red 0.1~2

[0091] Toner 0.5~3

[0092] Copper oxide 0.3 ~2.

[0093] Preferably, in the first embodiment of the brown glass of the present invention, its main raw material formula in parts by mass is as follows:

[0094] Quartz sand 160~200

[0095] Soda ash 40~55

[0096] Calcite 50~60

[0097] Glauber's salt 2~4

[0098] Iron red 0.1~1

[0099] Toner 0.5~2

[0100] Copper oxide 0.5 ~0.8.

[0101] Introduce copper oxide into the brown glass formula raw material, and use Cu in different states in the glass: Cu 0 Make the glass red, Cu + Make the glass red, Cu 2+ Makes glass appear azure. The brown glass of bottles and jars is reducing glass. After adding CuO to the formula raw ...

[0131] Preferably, in the third embodiment of the brown glass of the present invention, its main raw material formula in parts by mass is as follows:

[0132] Quartz sand 160~200

[0133] Soda ash 40~55

[0134] Calcite 50~60

[0135] Glauber's salt 4.5~6

[0136] Iron red 0.1~1

[0137] Toner 0.5~2

[0138] Copper oxide 0.4~0.6.

[0139] Introducing copper oxide and increasing the amount of Glauber's salt in the brown glass formula raw materials can significantly increase the red ratio of the brown glass and improve product quality.

[0140] It should be noted that the main raw material formula of the brown glass is 1000 parts by mass of various raw material dosages of molten glass.

[0141] The raw material of the brown glass also includes cullet, wherein cullet accounts for 65-85%, that is, cullet accounts for 650-850 parts.

[0142] Preferably, the cullet accounts for 75%.

[0143] Below with specific embodiment I to IV the raw material formula of brown glass of the ...

Abstract

The present invention discloses a brown glass, wherein the main raw material of the brown glass comprises 0.03-0.2% of copper oxide, or 0.3-0.8% of mirabilite, or 0.02-0.15% of copper oxide and 0.25-0.75% of mirabilite. The invention further discloses a preparation method for the brown glass. The preparation method comprises: weighing the materials according to the formula; adding the materials to a melting kiln, and melting at a temperature of 1500-1650 DEG C to prepare molten glass; carrying out a molding treatment on the molten glass; and carrying out an annealing treatment on the molten glass to obtain the brown glass. According to the present invention, copper oxide is introduced to the formula raw materials, or the amount of mirabilite is increased, or copper oxide is introduced and the amount of mirabilite is increased so as to achieve the purpose of increase of the red rate of the brown glass, and improve product color and quality.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to brown glass and a preparation method thereof. Background technique [0002] Brown glass is a kind of glass with anti-ultraviolet function. It is used in food packaging and has a good fresh-keeping effect. However, with the strengthening of competition in the glass industry, the cost pressure of various glass manufacturers is increasing. In order to control costs well, various enterprises Both increased the use of cullet. And cullet is a kind of social garbage. In addition to our current national conditions, the separation of garbage is relatively poor. Brown cullet is often mixed with many other variegated cullets. Therefore, when the proportion of cullet used for production increases, more variegated ion groups will be introduced into the glass, which seriously affects the color of the brown glass, that is, the red ratio of the brown glass, and also affects the UV protection ...
