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
The present invention is specifically related to a kind of formula of ceramic solar plate blank material.
Background technology
Due to the minimizing day by day of petroleum resources, people increase day by day to the demand of this clean energy of sun power, the technology of solar heat-collection plate has also obtained great development, common are in the market vacuum tube type heat collector, metal plate type heat collector, ceramic solar plate (hollow composite solar plate), there is the defect that valve tube intensity is low, frangible, work-ing life is short in vacuum tube type solar energy collecting plate wherein, and vacuum tube type solar energy collecting plate only has the function that adds warm air or water, do not there is the function of skin insulation.Although metal plate type solar energy collector has solved the above-mentioned defect of vacuum tube type solar energy, but because its material adopts copper, aluminum, cost is high, heat-insulating property is poor and metallic substance is easily corroded, still fall short of work-ing life, and the passage of its copper pipe is thin, the tortuous design of passage is affected greatly by incrustation scale.Ceramic solar plate adopts a kind of composite blank (material-mud), forms by sintering after mould once shaped, and corrosion-resistant, long service life, cost are low, and its inner heat exchanger channels is wide, is straight channel, and its circulation resistance is little, affected by incrustation scale little.Therefore hollow composite solar plate has been subject to consumers in general's welcome.The proportion that at present the hard material such as blank andesine accounts for is larger, and such hard material is main to have following defect at blank:
1) in the process of lapping of blank, need the longer time of consumption blank could be ground to the fineness of processing requirement, milling time is long, and power consumption is large;
2) plastics of blank are poor, poor fluidity;
3) hard material is too much, and the requirement for temperature in the time of sintering is stricter, and sintering temperature general control is at 1200 ℃ ± 20 ℃, and in sintering process, crackle too much easily appears in hard material, and yield rate is low, and the intensity of the plate body after sintering is also poor.
Summary of the invention
The object of the invention is to solve in the blank of current making hollow composite solar plate hard material too much, cause that blank milling time is long, energy consumption is large, plasticity is poor, easily occur crackle when poor fluidity, sintering, yield rate is low, the defect of sintering rear plate body intensity difference, provide a kind of take soft material as main, easy grinding, plasticity are good, the formula of good fluidity, yield rate is high, intensity is high ceramic solar plate blank material.
The present invention is achieved by the following technical solution:
Be a kind of formula of ceramic solar plate blank material, it is characterized in that comprising the raw material of following weight percent:
Feldspar: 14%～22%;
Clay: 14%～22%;
Black earth: 8%～14%;
Eluriate soil: 30%～48%;
Zhangqiu soil: 14%～22%;
Water glass: 0.1%～0.5%;
Ground caustic: 0.1%～0.5%.
As a preferred version of the present invention: the raw material that it is characterized in that comprising following weight percent:
Feldspar: 16.3%;
Clay: 16.3%;
Black earth: 10.4%;
Eluriate soil: 40%;
Zhangqiu soil: 16.4%;
Water glass: 0.3%;
Ground caustic: 0.3%.
In the present invention, the effect of water glass and ground caustic is the mobility that increases blank.
When blank of the present invention is made, step is as follows:
1) load weighted each raw material is put into ball mill, add the water of weight percent 25%～35%, grind 20 hours;
2) tail over 0.1～0.2.
Tool of the present invention has the following advantages:
1) blank is take soft material as main (soft material comprises clay, black earth, elutriation soil, Zhangqiu soil), and ball mill is short runtime, when economize on electricity, joint, reduces costs;
2) blank is take soft material as main, and mobility is relatively good;
3) blank is take soft material as main, and good shaping, does not ftracture, and yield rate is high, reaches more than 95%;
4) blank is take soft material as main, and work in-process are processed and processed well than like product;
5) blank is take soft material as main, and firing range is larger, and firing temperature is 1200 ℃ ± 30 ℃.
