++Carry out the soak at room temperature activation treatment in any one ion or the two or more ion solution and make plasthetics with long-acting sterilizing function.
For the ease of industrial production and application, further improving of the manufacture method of long effect sterilizing plastic cement is that activator solution concentration generally is controlled at: Ag
+Be 0.001～0.5M; Cu
++Be 0.05～2M; Zn
++Be 0.05～4M; NH
+
4Be 0.05～2M; Ni
++Be 0.05～2M.Can be used alone solution when carrying out activation treatment and also can use two kinds of mixed solutions of making more than the solution, activation treatment is carried out under the band temperature, and soak time is 2-10 hour.
For making the dispersing uniformity of antimicrobial component in plastic cement, to guarantee the reliable of anti-microbial property, employed silicate is chilled to normal temperature after oven dry when pulverizing, and preferably is made into particle diameter and is to mix with plastic cement behind 0.074～0.043 millimeter the meal to make plasthetics again.
Long effect sterilizing plastic cement manufacture method flow process provided by the invention is short, and equipment is few, and is easy and simple to handle, control easily, and activator level is few, can reduce process cost greatly, helps industrial production and uses also and can reduce production costs, and the performance of goods and quality are easy to guarantee.The anti-microbial property of goods is by actual measurement, and 8～24 hours killing rates of intestinal bacteria 8099 strains are 100%, and 8～24 hours killing rates of streptococcus aureus 6538 strains are 100%., to human body toxicological harmless effect human body skin is had no stimulation through the toxicological experiment proof, add composition quality, the performance of plastic cement are not had any detrimentally affect.
