Abstract
The invention discloses a low-expansion barbecue ceramic having an antibacterial function and a grill made of the ceramic and belongs to the technical field of preparation of inorganic material ceramic. The low-expansion ceramic of which the principal crystalline phase is a composite petalite/cordierite complex phase crystal structure is prepared from petalite, kaolin, soapstone and the like by adopting a common ceramic sintering method. The low-expansion ceramic with good thermal stability can be prepared without using expensive lithium-containing raw materials such as spodumene or lithium carbonate; infrared (sterilization) band radiance reaches far infrared (sterilization) band radiance, so that the product not only has a new health-care antibacterial function, but also has effective waste utilization and environment protection significance. The barbecue grill prepared from the ceramic has the following advantages that a ceramic barbecue plane has an antibacterial function, is low in expansion coefficient and also has a bacteria killing effect.
Description
Technical field
The invention belongs to inorganic materials ceramic technology preparation field, is the preparation method that a kind of low bulk barbecue with antibacterial is used pottery specifically.
Background technology
Barbecue is as people's a kind of popular leisure mode after work, more and more be subjected to people's favor, the kind of baking oven is also along with people's requirement increases and constantly increases, traditional baking oven generally is that iron or stainless steel are made, advantage is to conduct heat soon, but temperature was too high when shortcoming was roasted exactly, dangerous, when especially the one family has children and roasts, and cleaning also is suitable trouble, ceramic baking oven is also arranged in the market, disclose a kind of ceramic oven as CN201022643Y, the steely relatively baking oven of ceramic oven has better security.
Stupalith is divided into 3 classes according to the big I of the coefficient of expansion: high expansion class, middle expansion class, low bulk class.Stupalith is generally destroyed than being easier under thermal stresses, and thermal shock resistance is relatively poor, because thermal shock resistance depends primarily on the material coefficient of thermal expansion performance, so expansion ceramic material has excellent performance aspect resistance to sudden heating.At present, lithium low-expansion material commonly used is mainly based on expensive lithium raw materials that contains such as triphane or Quilonum Retards, triphane is expensive, and, exist because natural triphane is situation with the a-triphane, and change β type triphane during roasting to the 1000 ℃ left and right sides rapidly into, and follow 30% volumetric expansion, for avoiding causing deformation defect in the sintering procedure, before using, triphane must cause cost to increase through calcining.Baking oven has higher requirement to temperature in use, therefore, no matter from making the raw material pottery of ceramic baking oven, still from baking oven itself concerning the requirement of thermal characteristics, can utilize the low bulk barbecue will more and more be subjected to the welcome in market with the ceramic baking oven of making.
Infrared radiation ceramic refers to have at infrared band the inorganic materials of high emission frequency or feature transmitting frequency.As everyone knows, ir radiation not only can produce heat, and has the effect of sterilization, and people wish to obtain the food of safety and Health in the food that obtains delicious barbecue.
Far-infrared ceramic is a branch of new ceramics, is fired through scientific matching by multiple composition to form, and infrared light-wave that can radiation specific wavelength far away is widely used in fields such as energy-saving fuel, training rehabilitation, purifying air, body-care.The conventional ceramic that adopts kaolin such as silicon oxide, aluminum oxide to become to be grouped into traditional ceramics is different, far-infrared ceramic is to cooperate with different ratios respectively with kind of mineral compound surplus 20 and trace metal or specific natural crystal, form through 1200～1600 ℃ of high-temperature calcinations again, can give off the special ceramic material of specific wavelength far infrared rays.
Summary of the invention
Main purpose of the present invention is the deficiency at present technology, satisfies people to the various requirement of oven, provides a kind of and has the low bulk barbecue of antibacterial with ceramic.This present invention is raw material with petalite, kaolin, talcum etc.; adopt the conventional ceramic sintering method; generating principal crystalline phase is the low expansion ceramic of compound petalite/trichroite complex phase crystalline structure; do not use that triphane or Quilonum Retard etc. are expensive to contain the low expansion ceramic that the lithium raw material just can make Heat stability is good; the far infrared that infrared wave (sterilization) section radiant ratio reaches; not only make this product increase new health care antibacterial, and have effective utilization of waste material and environment protection meaning.
One of purpose of the present invention provides the ceramic prescription of low bulk barbecue that a kind of preparation has antibacterial, and this pottery is prepared from by following raw materials in part by weight:
Petalite 30-50%
Kaolin 20-45%
Talcum 1-5%
Quartzy 10-20%
Aluminum oxide 12-30%;
Petalite, Li[AlSi4O10], often contain impurity elements such as K, Na, Ca, Fe, originate in the pegmatite of hilllock, with symbiosis such as quartz, cleavelandite, lithionite, triphane, tourmalinite, polluxs, be the material that another kind that nature exists contains lithium.Crystal is column along (100), is block, tabular or needle-like output usually.It is complete to be polysynthetic twins, cleavage (001) according to (001), and (201) are medium, 114 ° in two groups of cleavage angles of cut, and fracture time conchoidal, property is crisp, hardness 6～6.5, relative density 2.3～2.5.White, colourless, grey or yellow, accidental pink or green, streak is colourless, is clear to translucently, and vitreous luster is pearliness on the cleavage surface.Mineral slowly heat the generation blue phosphorescent.At 1150 ℃ tangible heat absorption paddy is arranged on the differential thermal curve, at 1200 ℃ tangible exothermic peak is arranged.Petalite has extremely low thermal expansivity, compares with triphane, does not at high temperature have the variation of crystal formation, in pottery manufacturing field higher use value is arranged.
Kaolin is a kind of silicate minerals that contains aluminium, the ooze shape that is white in color, and the particle exquisiteness, shape is like flour.Its chemical ingredients quite stable is described as " omnipotent stone ".For manufacturing china and the main raw material of pottery, be rich in mineral substance such as silicon, zinc, magnesium, aluminium, chemical molecular skeleton symbol: Al
4(Si
4O
10) OH
6, except Al
2O
3Also contain SiO outward,
2
Talcum is a kind of common silicate minerals, generally is bulk, foliated lamellar, fibrous or radial, and color is white, canescence, and can be with shades of colour because containing other impurity.The purposes of talcum is a lot, as makes filler, agricultural chemicals absorption agent, leather coating, cosmetic and engraving materials of refractory materials, papermaking, rubber etc.Talcum is a kind of important ceramic raw material, and it is used for ceramic batch and glaze, introduces in the glaze as the chemical industry material, plays cooling, improves the effect of glaze surface roughness.
Another object of the present invention provides a kind of low bulk barbecue with antibacterial and uses ceramic panel, and this purpose is achieved by the following scheme:
