Abstract
The utility model relates to a ceramic cutter with a multilayered structure. A blade is sintered by at least two layers of appressed ceramic materials, wherein two adjacent layers adopt the ceramic materials with different toughness. Compared with the prior art, the ceramic cutter is technically characterized in that the firing shrinkage rate, the density and the material are different among a plurality of the materials, the performance advantages of various materials are complementary with each other; and the tensile stress or the pressure stress is produced on the surface of the cutter so that the ceramic cutter is uneasy to produce fracture and has large hardness and high toughness. Moreover, in production, a ceramic sizing agent is subjected to flow casting by utilizing a flow casting method to manufacture a soft ceramic plate which is not fired and has smooth surface; a plurality of layers of the ceramic plates are pressed in a warming and pressurizing mode; and the pressed ceramic plate has good interface bonding degree.
Description
Technical field
The utility model relates to life and industrial knife, relates in particular to sintex.
Background technology
Because ceramic material has high strength as aluminium oxide ceramics, silicon nitride ceramics, zirconia ceramics etc., and high rigidity is wear-resisting, high temperature resistant, and is corrosion-resistant grade for excellent properties, so the cutter of being made by ceramic material has had application very widely in recent years.Because the cutter made of zirconia ceramics has outward appearance such as jade, the non-corrosive variable color, characteristics that react with food not, ceramic table knife also is applied to modern kitchen gradually.Present ceramic table knife is mainly made by the dry-pressing formed method of ceramic powders, and this method can only be made the single-layer ceramic cutter.Because it is low that ceramic material itself has tensile strength, the characteristics that fragility is big, embrittlement often takes place in such cutter in practice easily.In addition,, therefore in forming process, need to increase thickness, increase the polishing surplus, improved production cost because the tool surface that dry pressing is made is coarse.
The utility model content
The utility model is big in order to overcome existing sintex fragility, needs the too much defective of polishing in process, and a kind of sandwich construction sintex is provided, and improves the toughness of sintex, and makes the fineness of tool surface better, processes more convenient.
Above-mentioned purpose is realized by following technical scheme:
A kind of sandwich construction sintex is characterized in that, blade is to be formed by two-layer at least ceramic material sintering of combining closely.Wherein, adjacent two layers adopts the different ceramic material of toughness.
The sintex that the utility model provides is than the characteristics of prior art: owing to percent of firing shrinkage, density or material difference between the multilayer material, make the advantage of multiple material be able to complementation, surface at cutter produces tensile stress or compression, make that Stupalox of the present utility model is difficult for producing embrittlement, hardness is big, toughness is high.In addition, can utilize The tape casting curtain coating ceramic size during production, make the soft potsherd of unfired, make the multi-layer ceramic chip pressing by the pressing mode of heating, through the potsherd of compacting, interface junction is right good, smooth surface.

Description of reference numerals: 1. blade, 11. ground floor ceramic materials, 12. second layer ceramic materials, 13. the 3rd layers of ceramic material.
The specific embodiment
Embodiment one
Please in conjunction with consulting Fig. 1 and Fig. 2, embodiment one provides a kind of double-layer structure sintex, what its blade 1 was close to is formed by ground floor ceramic material 11 and second layer ceramic material 12 sintering, the different ceramic material of this two-layer employing toughness, can in aluminium oxide ceramics, silicon nitride ceramics, zirconia ceramics, select, also can in existing other ceramic material, select.
Embodiment two
Please in conjunction with consulting Fig. 3 and Fig. 4, embodiment two provides a kind of three-decker sintex, its blade 1 is formed by the ground floor ceramic material of being close to 11, second layer ceramic material 12 and the 3rd layer of ceramic material 13 sintering, these three layers are adopted the different ceramic material of toughness, can in aluminium oxide ceramics, silicon nitride ceramics, zirconia ceramics, select equally, also can in existing other ceramic material, select, also can in the same ceramic material of different-grain diameter, select.According to different demands, can adopt hardness height, ceramic material that toughness is low on the cutter both sides, adopt the high ceramic material of toughness in the centre; Perhaps the high ceramic material of toughness is adopted on the cutter both sides, adopts the high ceramic material of hardness in the centre, and the advantage of storeroom is able to complementation like this, produces the cutter that the hardness height is not easy embrittlement again.
Introduce the preparation method of blade 1 below: the different ceramic size of (1), composition becomes the ceramic film of unfired with the The tape casting curtain coating; (2), with ceramic film by the pressing mode lamination pressing of heating; (3), will put into kiln through the ceramic body of pressing and forming and be fired into the sintex blank; (4), the ceramic material that bakes is carried out Surface Machining, polishes, puts the first edge on a knife or a pair of scissors, make the cutting sintex.
The utility model has adopted the structure of multilayer, because percent of firing shrinkage, density or material difference between the multilayer material, make the performance advantage of multiple material be able to complementation, surface at cutter produces tensile stress or compression, make and do not sacrificing under the big intrinsic property situation of sintex hardness, promote the toughness of cutter, be difficult for producing embrittlement.In addition, during production, because green bodies used therein is made by The tape casting, institute's one-tenth cutter blank smooth surface can not carried out the secondary polishing, has saved production cost of products; By the potsherd that the pressing mode of heating is got up the pressing of multi-layer ceramics base sheet lamination, interface junction is right good.
The utility model can be daily life with ceramic table knife, paring knife, also can be the industrial ceramic cutter Sheet, or ceramic dagger, sabre etc. Made product has high temperature resistantly, anticorrosive, and hardness is strong The time overcome like product poor toughness, frangible shortcoming.
