Problems solved by technology
[0006] The purpose of the present invention is to solve the problem that there are too many hard materials in the blanks for making hollow composite solar panels at present, resulting in long grinding time of the blanks, high energy consumption, poor plasticity, poor fluidity, easy cracks during sintering, and low yield. To overcome the defect of poor body strength, provide a ceramic solar panel blank that is mainly made of soft materials, easy to grind, good plasticity, good fluidity, high yield, and high strength

Embodiment 1
[0035] The weight percent of each raw material of present embodiment is as follows:
[0036] Feldspar: 14%;
[0037] Clay: 14%;
[0038] Black soil: 8%;
[0039] Elutriation soil: 45.8%;
[0040] Zhangqiu soil: 18%;
[0041] Water glass: 0.1%;
[0042] Alkali powder: 0.1%.
[0043] When the blank of the present embodiment is made, the steps are as follows:
[0044] 1) Put the weighed raw materials into a ball mill, add 25% water by weight, and grind for 20 hours;
[0045] 2) The remaining sieve is 0.15.
[0046] After testing, the fluidity of the blank prepared in this embodiment is 18 seconds, the plasticity is good, easy to form, no cracking, and the yield is high, reaching more than 95%.

Abstract
The invention specifically relates to a formula of ceramic solar panel blanks. The ceramic solar panel blanks are characterized by comprising the following raw materials by weight: 14-22% of feldspar, 14-22% of clay, 8-14% of black soil, 30-48% of elutriation soil, 14-22% of Zhangqiu soil, 0.1-0.5% of water glass, and 0.1-0.5% of alkali powder. The ceramic solar panel blanks have the following advantages: (1) as the blanks take soft materials as the principal materials (the soft materials comprise the clay, the black soil, the elutriation soil and the Zhangqiu soil), the operation time of a ball mill is short, the electricity and the time are saved, and the cost is lowered; (2) as the blanks take the soft materials as the principal materials, the mobility is better; (3) as the blanks take the soft materials as the principal materials, the formation is easy, the crack is not generated, and the yield is as high as above 95%; (4) as the blanks take the soft materials as the principal materials, the treatment for semi-finished products is easier as compared with similar products; (5) as the blanks take the soft materials as the principal materials, the firing range is wider, and the firing temperature is 1200 plus or minus 30 DEG C.
Description
technical field [0001] The invention specifically relates to a ceramic solar plate blank. Background technique [0002] Due to the dwindling oil resources, people's demand for solar energy, a clean energy source, is increasing, and the technology of solar collectors has also been greatly developed. At present, vacuum tube collectors and metal plate collectors are common in the market. ceramic solar panels (hollow composite solar panels), among which the vacuum tube solar heat collector has the defects of low vacuum tube strength, fragility, and short service life, and the vacuum tube solar heat collector only has the function of heating air or water, not It has the function of building exterior wall insulation. Although the metal plate solar collector solves the above-mentioned defects of the vacuum tube solar collector, its service life is still not long enough due to its material of copper and aluminum, high cost, poor thermal insulation performance, and the metal materia...
