Abstract
The present invention provides a method for making large-size photothermic converting elements of vanadium-titanium black ceramics by using extracted vanadium tailings as a main raw material. A large-size hollow plate of vanadium-titanium black ceramics is made of extracted vanadium tailings and ordinary ceramic raw materials by a rolling method, a damp-dry pressing method, an extruding method and a slurry injection method; one surface of the hollow plate is covered with a heat-insulation material to form an infrared plate of the vanadium-titanium black ceramics, and then the other surface of the hollow plate is in sealing connection with a glass plate and is pumped into a vacuum to form a vacuum solar plate of the vanadium-titanium black ceramics. The infrared plate of the vanadium-titanium black ceramics and the vacuum solar plate of the vanadium-titanium black ceramics are totally named photothermic converting elements of the vanadium-titanium black ceramics.
Description
(1) technical field
The present invention relates to the manufacture method of photo-thermal conversion elements, specifically about the manufacture method of vanadium-titanium black ceramic large size photo-thermal conversion elements, saying so in more detail, sunlight absorbs, the manufacture method of the vanadium-titanium black ceramic large size photo-thermal conversion elements of ir radiation about being used for.
(2) background technology
It is the method that one of raw material is produced various black ceramic goods with the tailings in vanadium extraction that Chinese patent CN85102464 has narrated, and the present invention is to the improvement of aforesaid method and development.
With the vanadium titano-magnetite is that raw material is produced vanadium slag, leaches vanadic salts from vanadium slag, and remaining residue is called tailings in vanadium extraction.Tailings in vanadium extraction is mixed with common ceramic raw material, and when tailings in vanadium extraction content during greater than 30% (weight), the black ceramic goods of manufacturing are called the vanadium-titanium black ceramic goods, and this stupalith is called vanadium-titanium black ceramic.The compound of Fe, Mn, Ti, Cr, V accounts for more than 15% of gross weight in the vanadium-titanium black ceramic, and SiO in the conventional ceramic
2, Al
2O
3Account for gross weight more than 90%, both processing performances and material property all have than big difference.Can launch infrared-ray when vanadium-titanium black ceramic is heated, have higher infrared emittance, vanadium-titanium black ceramic can a large amount of energy that absorb in the sunlight during by solar radiation, have higher sunlight absorption rate, and vanadium-titanium black ceramic is good optical-thermal conversion material.
The vanadium-titanium black ceramic integral black, the intensity height, physicochemical property is good, and former vanadium-titanium black ceramic is used to produce the decorative panel for building of solid surface grinding in a large number, is used for decorating building.Black display is sedate, serious in the building decoration, and the vanadium-titanium black ceramic decorative sheet utilizes pure this characteristic of vanadium-titanium black ceramic black exactly, and its photo-thermal conversion characteristic does not obtain abundant development and utilization.
(3) summary of the invention
The objective of the invention is photo-thermal conversion performance for abundant development and utilization vanadium-titanium black ceramic.
The present invention is achieved in that tailings in vanadium extraction is mixed with common ceramic raw material, tailings in vanadium extraction content is no less than 30% (weight), be generally 40～60%, said mixture is called the vanadium-titanium black ceramic raw material, in this mixture, evenly sneak into filamentary material to increase biscuit intensity, after conventional ceramic process is handled, with roll forming or half-dried transfer moulding method, be shaped to 3～10 millimeters of thickness, shadow area is not less than 0.2 square metre, be generally 0.2～5 square metre vanadium-titanium black ceramic biscuit plate, biscuit plate drying, be sintered into the vanadium-titanium black ceramic flat board with 1050-1200 ℃ temperature, two vanadium-titanium black ceramics are dull and stereotyped parallel separated by a distance, two ends are provided with access way mouth and end plate, all around and be lower than the bond material sealing-in of vanadium-titanium black ceramic between each junction surface such as middle liner plate with tackiness agent or firing temperature, through solidifying or being fired into vanadium-titanium black ceramic large size hollow sheeting, will the glass plate more bigger be placed on the heat-resisting die and heat than hollow sheeting size, pressurization makes sheet glass recessed with mould, hollow sheeting is placed on the sheet glass through preheating, attemperation, pressure makes sheet glass and hollow sheeting sealing-in, also can adopt the sheet glass elder generation moulding way of sealing-in again, the cavity that forms between sheet glass and hollow sheeting is vacuumized and seals, at hollow sheeting back side lining lagging material and form one, such composition board is called vanadium-titanium black ceramic vacuum solar plate, with the glass surface of solar panel to the sun, extract the medium that temperature raises in the hollow sheeting and promptly obtained energy, above-mentioned vanadium-titanium black ceramic hollow sheeting is cover glass layer and well heater is set in hollow sheeting or feeds hot-fluid in hollow sheeting not, infrared-ray will be outwards launched on the hollow sheeting surface, and this moment, the hollow plate body was known as the vanadium-titanium black ceramic infrared panel.
Vanadium-titanium black ceramic vacuum solar plate and vanadium-titanium black ceramic infrared panel are referred to as vanadium-titanium black ceramic large size photo-thermal conversion element.
For increasing biscuit and product strength, in raw material, add various inorganic, organic fibrous materials, macrofiber and staple fibre are as ceramic fiber, glass fibre, carbon fiber, nylon fiber, flaxen fiber etc.
Two vanadium-titanium black ceramics are hardened be combined into hollow sheeting and can adopt multiple ways such as machinery, organic materials gluing, inorganic materials sintering, can adopt ambient cure, heat reactive resin, can adopt ceramic mud bar, ceramic mud combination, drying, be sintered to one, but also can adopt spontaneous coagulation material such as high-strength cement class material in air, and the material that combines with sizing agent of cement etc.
The vanadium-titanium black ceramic hollow sheeting can adopt two dull and stereotyped bonded modes to constitute, and also can adopt vacuum pugging, the way moulding of major diameter forcing machine extruding cellular plate and the way of gypsum mold injection forming to make.
Vanadium-titanium black ceramic has higher intensity, and additional glass plate and lagging material can further improve its rigidity, and vanadium-titanium black ceramic vacuum solar plate can be used as roof and wall covering, collects sun power simultaneously.
(4) description of drawings
Describe characteristics of the present invention in detail below in conjunction with accompanying drawing:
Fig. 1 is with the dull and stereotyped vanadium-titanium black ceramic large size hollow sheeting that combines with bond material with lead-in, end plate, access way mouth of two vanadium-titanium black ceramics.Bond material is normal temperature or the organic materials that is heating and curing, also can be the inorganic materials that sintering temperature is lower than vanadium-titanium black ceramic.When the fluid of comparatively high temps passed through hollow sheeting, the vanadium-titanium black ceramic plate gave off infrared-ray.Do not install in the hollow sheeting of porthole and end plate and can penetrate heating unit, heating makes the vanadium-titanium black ceramic plate give off infrared-ray.Infrared-ray can be used for human body infrared physiotherapy and heating object.
The vanadium-titanium black ceramic large size hollow sheeting that Fig. 2 makes with the method that extrudes porous plate through vacuum pugging, go up and with the sheet glass sealing-in, formed cavity vacuumizes, lining lagging material and form one below, become vanadium-titanium black ceramic vacuum solar plate, when solar radiation, the fluid in the hollow sheeting is heated.
