 摘要
以硝酸银和碘化钾为原料配置碘化银，并在搅拌的情况下与大白浆充分混合，制备纳米级的碘化银大白浆溶液。取大肠杆菌作为试验菌种，进行传代培养，获得大量活体菌样。制备多个牛肉膏蛋白胨普通培养基，取不同浓度的纳米碘化银大白浆溶液分别涂抹与多个培养基上并将大肠杆菌均匀涂布于这些培养基中。制备出空白，只涂大白，只涂菌，涂菌与不同浓度碘化银大白浆溶液的多个试验观察培养基。结果发现，随着碘化银大白浆溶液浓度的增加有很好的抗菌性，效果接近于100%。

Silver iodide for the interior walls of the antimicrobial coatings
With silver nitrate and potassium iodide for the allocation of raw materials silver and mixing in the case of pulp and revealed the full hybrid, the preparation of nano-silver revealed slurry solution. As a test for E. coli bacteria, Chuan culture, access to a large number of live bacteria-like. Preparation of a number of beef extract peptone ordinary medium, for different concentrations of nano-silver iodide solution were applied revealed pulp with a number of medium and E. coli in these uniform coating medium. Preparation of a blank, revealed only Tu, Tu only bacteria, coated with different concentrations of silver iodide solution pulp revealed a number of experimental medium. The results showed that, with silver iodide solution revealed the increasing concentration of pulp a very good antimicrobial effects close to 100%.

Keywords: Silver iodide, Interior paint, Antibacterial agents.
