Description
Technical field
The present invention relates to a kind of nanometer antibiotic chopping block and method for making thereof, especially refer to that a kind of at least simultaneously formation in sheet chopping block body is subjected to tangent plane, this is had by tangent plane and suitably accounts for thickness, and be the macromolecular material base material, and evenly be mixed with particle diameter in the inside that is subjected to tangent plane and be time micron or littler and have antibiotic dynamopathic oxide powder, and make chopping block have better antibiotic and self-cleaning effect.
Background technology
Present most habitual chopping block, all design does not have antibiotic structure, or do not pass through antibiotic processing, because chopping block is the usefulness of cutting for Shi Wu Duo, residual swill is easy to multiply bacterium on chopping block, commonly use the chopping block that is not provided with antibiotic structure or antibacterial treatment, during use, the bacterium that is multiplied just can contaminated food, and health is caused serious harm.
In order to make chopping block have antibacterial functions, commonly use the minority chopping block at present and have antibiotic design, this commonly uses antibiotic design, be to form at chopping block body end face and the bottom surface one upper and lower antibiotic chopping block layer of fitting, this chopping block body is the plastic plate by the PP of homogenous material or PE plastic material institute extrusion molding, and has preset thickness, this upper and lower antibiotic chopping block, be to add an amount of antiseptic institute extrusion molding, and fit in the end face and the bottom surface of chopping block body at chopping block body extrusion molding in the lump by PP or PE plastics.Yet, this commonly uses antiseptic that chopping block is adopted not is function oxidate powder kernel structure for inferior micronization or nanometer, but chemical agent or other molecular structures are formed, therefore, its abrasion resistance, structural strength a little less than, and not by the antiseptic of inferior micronization or nanometer, its bag is mixed in the chopping block body, antibacterial efficacy also can't be brought into play, and its antibacterial effect is not good, thereby rarely has finding on the market at present.
Moreover, another kind of habitual structure and aforementioned habitual structure are roughly the same, different just both production method differences, its antiseptic does not adopt to have function and is the powder structure of time micronization or nanometer, but chemical agent or other molecular structures are formed, therefore, abrasion resistance, structural strength a little less than, and not by the antiseptic of inferior micronization or nanometer, its bag is mixed in the chopping block body, antibacterial efficacy also can't be brought into play, and its antibacterial effect is not good.
Summary of the invention
Main purpose of the present invention, be to provide a kind of abrasion resistance and hardness that promotes chopping block, and can effectively improve bacterium and multiply, and tool is antibiotic and the nanometer antibiotic chopping block of self-cleaning effect, it is at least simultaneously to form at sheet chopping block body to be subjected to tangent plane, principal character is to be subjected to tangent plane to have suitable thickness at this, and is the macromolecular material base material, and portion evenly is mixed with particle diameter and is time micron or littler and have an antibiotic dynamopathic oxide powder within it.
The invention has the beneficial effects as follows:
1. chopping block body of the present invention not only has antibacterial efficacy because of being mixed with the oxide powder of nanometer, and makes this its surface texture of body formed back of chopping block change, and has surface or the effect of structure upgrading, and the relative hardness of this chopping block and abrasion resistance are promoted.
2. chopping block body of the present invention is because of being mixed with the antibiotic function oxide powder of nanometer tool, make bacterium can't in chopping block be subjected to multiply on the tangent plane, so can improve the security in the use and promote dietetic hygiene.
The invention will be further described below in conjunction with the drawings and specific embodiments.
