Background technology
Chopping board is indispensable kitchen tools in the people's lives, and former chopping board is many based on wood, and its advantage is durable, shortcoming for heavy, not easy to clean, be not easy placement, slowly replaced by the plastics chopping board.The plastics chopping board that we use always is because of technological reason, and the chopping board plate body is heatproof not, and the chance thermal capacitance is yielding.As everyone knows, bacterium is the easiest conceals and moist, the competent place of moisture, and the speed of breeding in such place is exceedingly fast, for example: intestinal bacteria are under the suitable condition of growth three elements (temperature, moisture and nutrient), intestinal bacteria can reach 100,000,000 after 9 hours, promptly with the numeral breeding surprising like this up to 108 times.So the place of the kitchen survival and reproduction that to be bacterium best must be carried out necessary antibioticly, could guarantee our quality of life, healthy.Therefore by in sheet table trencher plate body, adding antimicrobial macromolecule material, make the table trencher plate body have germ resistance, reach antibiotic, sterilization effect has positive effect, mainly is by adopting the inorganic silver ion to reach antibacterial effect.At present, anti-biotic material mainly contains two (three kinds) series, and a kind of is plants antimicrobial, and a kind of is organic series, and a kind of is inorganic series.(see also following network address:
Http:// www.kjj.com.cn/zyk/show.asp? idx=13http: //www.sr-business.com/art Icle view.asp? bigtypeid=7﹠amp; Smalltypeid=46﹠amp; Id=51) organic system is shown many types, in general is the goods similar to agricultural chemicals, some in addition can bring out cancer.Mostly be unsettled material, evaporation and decomposition easily about temperature to 300 degree.Otherwise the anti-biotic material of inorganic series is made up of inorganic substance.Even if the temperature of ester moulding can not influence its function.The silver of inorganic serial anti-biotic material composition (Ag), copper (Cu) and inferior plumbous (Zn) etc. also have outstanding security.
The comparison of inorganic and organic anti-bacterial material effects:
The antibiotic mechanism of inorganic antibacterial material is contact-type, passive type, and the antibiotic mechanism of organic anti-bacterial material is dissolution type, and is active.
The antibiotic mould resistance of inorganic antibacterial material is that spectrum is antibiotic, lasting, water-fast, acid and alkali-resistance, wash resistant etc., and the antibiotic mould resistance of organic anti-bacterial material is unidirectional antibiotic, quick-acting, easily runs off in water, washs and fall effect etc.
The heat-resisting photostabilization of inorganic antibacterial material is heat-resisting greater than 800 degree, and illumination is aging not heat-resisting, and the heat-resisting photostabilization of organic anti-bacterial material is less than 300 degree, illumination ageing.
The resistance of inorganic antibacterial material is difficult for producing, and the bacterium of organic anti-bacterial material can develop immunity to drugs.
Inorganic antibacterial material is easy to change, and the organic anti-bacterial material is not easy to change.
Inorganic antibacterial material is harmless to the health, non-secondary pollution, and security is good, and organic anti-bacterial material breakdown product has certain toxic side effect even the carcinogenic poor stability of some monomer,
Inorganic antibacterial material must be made ultrafine powder and be evenly distributed in product surface, and is selective to carrier, and the organic anti-bacterial material easily disperses, mixing, filling, but clearly easily goes out crystal.
Therefore inorganic antibacterial material in use has superiority and security.
Macromolecular material is made different antimicrobial products, and available diverse ways adds anti-biotic material.Certainly, the net effect after the interpolation is also different, is example to produce the plastics antimicrobial prod, can adopt anti-biotic material, antibacterial matrices, antibiotic plastic to produce.Since directly use the method for anti-biotic material can influence plastics outward appearance, cause antimicrobial efficiency to reduce, and the tooling cost of using antibiotic plastic to produce is higher, and the plastics processing mode of more employing is to adopt the method for adding antibacterial matrices to produce antibacterial plastic product in the world at present.
