Embodiment 1

[0012] Embodiment 1: the solar cell encapsulating glass of production presses following method and step, a, select raw material: select quartz sand, soda ash, calcite, salt of wormwood, alumina, Glauber's salt, magnesia and cullet to make raw material; And to soda ash, Potassium carbonate, aluminum oxide, Glauber's salt, and magnesium oxide are tested for their iron content. The iron content in each raw material can only be used within the range of 0-0.0001% of its weight; the selected cullet should be colorless;

[0013] b. Processing of selected raw materials: Wash the selected quartz sand raw materials with an acidic solution made of sulfuric acid and water to remove the iron in them. The washed quartz sand should be tested. When the iron content in the quartz sand is 0-25ppm, it can be used; the broken glass should be cleaned;

[0014] c. According to the produced glass components, calculate the weight of various raw materials required, and weigh various raw materials that...

Embodiment 2

[0020] Embodiment 2: the production method in the present embodiment and step are identical with embodiment 1, but in step b, be to add the acidic liquid that water is made with nitric acid to wash the quartz sand raw material that selects, remove the irony in it;

[0021] In step c, when weighing and mixing raw materials, use stainless steel containers to hold them, and use stainless steel tools to mix and transport; when raw materials are added to the kiln for melting, the temperature of the hot spot in the kiln is 1540-1555 °C, and the temperature of the cooling part is 1165- 1190°C, the fluctuation range of the glass liquid level in the furnace is 0-0.5mm;

[0022] The temperature at the outlet of the molten glass in the kiln is 1090-1120°C. Other steps and requirements are the same as in Example 1.

[0023] The height H of the kiln ridge in the present embodiment is 720mm, and other structures are the same as in Embodiment 1.

Embodiment 3

[0024] Embodiment 3 The production method and steps in this embodiment are the same as those in Embodiment 1, but in step b, the acid solution made by adding water with hydrochloric acid is used to wash the selected quartz sand raw material to remove iron in it;

[0025] In step c, when weighing and mixing raw materials, use stainless steel or aluminum containers to hold them, and use stainless steel or aluminum tools to mix and transport; The temperature is 1170-1240°C, and the fluctuation range of the glass liquid level in the kiln is 0-0.6mm;

[0026] The temperature at the outlet of the molten glass in the kiln is 1105-1120°C. For the convenience of storage and product transportation, the annealed glass products should also be cut, packaged or boxed.

[0027] Other steps and technical requirements are identical with embodiment 1.

[0028] The height H of the kiln ridge in the present embodiment is 740mm, and other structures are the same as in Embodiment 1.
