The antifouling, antimicrobial, elution behavior, skin irritant, and cytotoxicity properties of water-soluble phosphate glass on stainless steel were evaluated. Water-soluble phosphate glass samples with 35% Cu (mol/mol) were prepared by altering the network modifier (Na2O, K2O) and network former (P2O5, B2O3) compositions. The materials were melted at temperatures within the range of 850-950 °C. The melt was then quenched and ground into fine particles using a twin roll mill. The resulting water-soluble glasses were prepared as glass frit (size < 100 μm) using a sieve. The amorphous phase was determined by X-ray diffraction and differential thermal analysis. Water-soluble glasses with a reduced Cu ion elution rate of 1.2 ppm per week were formed because the chemical resistances of the formulated glasses improved as the P2O5 content decreased and the B2O3 content increased. To test its antifouling properties, the glass frit was mixed with paint and coated onto a STS316L sheet. The surface roughness was increased markedly from 1.4 to 19.2 nm, increasing the specific surface area for antimicrobial activity. It was demonstrated that the proposed method was able to form noncytotoxic, nonirritant, water-soluble glasses with 99.9% antimicrobial activity against Staphylococcus aureus. These results suggest that water-soluble phosphate glass on STS316L sheets could be useful in filtration plants.

水溶性磷酸盐玻璃粉对过滤厂的防污作用。

评价了水溶性磷酸盐玻璃在不锈钢上的防污，抗菌，洗脱行为，皮肤刺激性和细胞毒性。通过更改网络改性剂（Na2O，K2O）和网络形成剂（P2O5，B2O3）的组成，可以制备具有35％Cu（mol / mol）的水溶性磷酸盐玻璃样品。所述材料在850-950℃的温度范围内熔融。然后将熔体淬火并使用双辊磨机研磨成细颗粒。使用筛子将所得的水溶性玻璃制成玻璃料（尺寸＜100μm）。通过X射线衍射和差热分析确定非晶相。水溶性玻璃，Cu离子洗脱速率降低为1。每周形成2 ppm，因为随着P2O5含量的减少和B2O3含量的增加，配制玻璃的耐化学性提高。为了测试其防污性能，将玻璃料与涂料混合并涂在STS316L板上。表面粗糙度从1.4 nm显着增加到19.2 nm，增加了抗菌活性的比表面积。结果表明，所提出的方法能够形成对金黄色葡萄球菌具有99.9％抗菌活性的无细胞毒性，无刺激性的水溶性玻璃。这些结果表明，STS316L板上的水溶性磷酸盐玻璃可用于过滤厂。表面粗糙度从1.4 nm显着增加到19.2 nm，增加了抗菌活性的比表面积。结果表明，所提出的方法能够形成对金黄色葡萄球菌具有99.9％抗菌活性的无细胞毒性，无刺激性的水溶性玻璃。这些结果表明，STS316L板上的水溶性磷酸盐玻璃可用于过滤厂。表面粗糙度从1.4 nm显着增加到19.2 nm，增加了抗菌活性的比表面积。结果表明，所提出的方法能够形成对金黄色葡萄球菌具有99.9％抗菌活性的无细胞毒性，无刺激性的水溶性玻璃。这些结果表明，STS316L板上的水溶性磷酸盐玻璃可用于过滤厂。
