随 经济 飞 speed development, 人们生 active water 平 不断 improve/increase, for/regarding 自身舒适, and safety active ring 境也愈发 heavy 视. 而我们 day active need use to material product upper 往往会存 in a large amount of fine 菌, 霉菌甚至病毒, 时刻威胁我们 身体健康, therefore tool has 杀菌, property can antimicrobial material 备受关注, antimicrobial plastics ､ antimicrobial fiber, antimicrobial 陶瓷､ antimicrobial metal material and other, widely used in home appliances, building materials, decoration material, textile product, clothing/apparel, tool, 卫生洁 tool and other field/area.

antimicrobial plastics core formed separation is antimicrobial agent, will a small amount of antimicrobial agent add polymer/macromolecule material in made formed antimicrobial resistant polymer/macromolecule, its versus products tool has 卫生自洁 function, decrease/reduce use polymer/macromolecule products 而发生 交叉污染.

antimicrobial agent in plastics in dispersion property and and plastics versus property is made antimicrobial plastics key/critical. antimicrobial plastics production process complex, not only need meet/satisfy plastics 本身应该 tool property can, meanwhile tool antimicrobial function, commonly used antimicrobial plastics made methods has 直接添 add method, antimicrobial masterbatch method, surface combined method, lamination method and rear processing method and other.

1, 直接添 add mixing/compounding method

直接添 add mixing/compounding method is will antimicrobial agent add to plastics raw materials in, through material 理手段 make antimicrobial agent other material separation mixed combined rear, 直接进行 molding processing, made to versus antimicrobial plastics products.

直接添 add method as simple, antimicrobial agent add amount can control, disadvantages is antimicrobial agent in antimicrobial products in distribution although uniform, antimicrobial agent in plastics in dispersion property material, antimicrobial agent versus property and processing process made, antimicrobial agent is 以一定 团 poly distribution in plastics in, dispersion property can 差, therefore versus for antimicrobial property can relatively 差.

2, antimicrobial agent masterbatch method

is 避免直接添 add method made antimicrobial products in macro uniform, micro dispersion property issues, can will antimicrobial agent and resin or and resin has good versus property resin through di screw extrusion machine extrusion made formed antimicrobial masterbatch, generally antimicrobial masterbatch in antimicrobial agent concentrated degree is antimicrobial products in antimicrobial concentrated degree 25倍 or 50倍, antimicrobial significantly.

图 antimicrobial masterbatch  图 sheet/slice large 科技

due to in made masterbatch process in antimicrobial agent and resin di screw and combined, again through molding process dispersion, masterbatch antimicrobial agent in antimicrobial products in dispersion property relatively 直接添 add method need good more, but also use antimicrobial masterbatch pellets 状, in molding as in powder 尘飞扬, decrease/reduce formed process 污染, use process need for antimicrobial agent surface treatment, optimization antimicrobial plastics products production process.

therefore, antimicrobial agent masterbatch rear made antimicrobial products formed is currently antimicrobial products most main/primary production methods.

3, surface bonding method

surface bonding method is will antimicrobial agent in products molding mold surface, injection molding antimicrobial agent in products surface formed antimicrobial products, has use add antimicrobial agent film or plastics thin sheet/slice 先安置 in molding mold inner, injection molding will film or thin sheet/slice in products surface formed antimicrobial products.
this type of methods can reduce antimicrobial agent use amount, is application scope relatively narrow, can in has mold plastics product in use.

4, lamination method

lamination method is will antimicrobial agent and plastics made formed antimicrobial thin sheet/slice, will thin sheet/slice combined in need plastics products surface, in lamination equipment inner hot pressure formed antimicrobial products, its advantages in can selection antimicrobial 部位, improves antimicrobial has 效面积.

5, rear processing method

rear processing method is in plastics products made formed rear in plastics parts surface 进行处理, make its tool antimicrobial property can. currently using/adopting methods has surface method and true 空溅射 surface method, will antimicrobial agent 附 于 plastics product surface, processing equipment cost relatively high, 不利于规模化 application.
