Description
Technical field
The utility model belongs to technical field of alloy material, is related to a kind of antibacterial titanium alloy composite board, especially a kind of
It can be applied to the antibacterial titanium alloy composite board of cookware manufacture.
Background technology
Using cookware as the kitchen tools of representative in use, need to contact with food for a long time, and in the process of heating
In, it needs for heat to be transmitted to internal food well.Therefore, for a long time, being used to prepare the plank of this kind of product all needs
Have：1) good foodsafety, 2) good corrosion resistance, 3) thermal conductivity is good, and 4) non-corrosive is beautiful.
The surfaces externally and internally of kitchen tools due to the use of function difference require also differ, wherein inner surface is contacted with food, because
This wishes there is extraordinary corrosion resisting property, and does not contain the element being hazardous to the human body in material preferably.Outer surface needs
The heat of heat source is quickly and uniformly transmitted to internal layer, achievees the effect that rapid and uniform heating and energy saving.
The material for being presently used for cookware preparation is mainly aluminium, iron, steel, stainless steel and its composite board and pure titanium.Aluminium and
Aluminium alloy for cookware manufacture, heat conduction is fast, but can dissolve out aluminium element in use, into human body after enrichment will produce pair
Effect, such as cause the diseases such as senile dementia.Iron and ordinary steel corrosion resisting property are poor, get rusty easily, and also easily cause iron or oxygen
Change iron excess intake, harm is generated to liver.The corrosion resisting property of stainless steel is good, non-corrosive, beautiful, but containing big in stainless steel
The nickel element and chromium of amount will produce metal allergy after taking in human body, or even cause canceration.Pure titanium has been widely used in
In the manufacture of human body implantation instrument, biomaterial the safest is had been considered to, is free of heavy metal nickel and chromium, even long
Phase use will not the harmful elements such as Aluminum, nickel and chromium, be applied in cookware manufacture, but the thermal conductivity ratio of pure titanium
Poor, heating is slow and uneven.
Existing another question is exactly to be easy to grow thin in the environment of relative humidity to cookware in use
Bacterium goes mouldy, and causes disease.The problem of in order to eliminate bacteria breed, in having there is technology to prepare antimicrobial coating for cookware, but
It is that antibiotic property can slowly be eliminated with falling off for coating in use.
How to develop it is a not only there is Thermal conductivity, but also bacteria breed can be prevented, and the kitchen tools without heavy metal
Plank just becomes the important problem of kitchen tools development continual exploitation.
Utility model content
