Embodiment 1
[0027] A preparation method of an antibacterial and mildew-proof stainless steel coating containing silver, zinc and cerium, the steps are as follows:
[0028] 1. Add a sufficient amount of sodium dihydrogen phosphate aqueous solution to the zinc oxychloride aqueous solution to react to obtain a nano-sized zinc phosphate carrier, add a surfactant to control the particle size, and the added surfactant is PEG (polyethylene glycol) , the above-mentioned surfactants can also prevent the agglomeration between colloidal particles during the carrier precipitation process.
[0029] 2. Put the nano-zinc phosphate carrier into the ultrafiltration membrane system for filtration. The operating temperature of the ultrafiltration membrane system is 10°C, the operating pressure is controlled at 3 bar, and its operating time is controlled at 8 hours.
[0030] 3. Add pure water to dissolve the sol precipitation of the nano-zinc phosphate carrier, and then add an aqueous solution of antibacter...
Embodiment 2
[0037] A preparation method of an antibacterial and mildew-proof stainless steel coating containing silver, zinc and cerium, the preparation steps are as follows:
[0038] 1. Add a sufficient amount of sodium dihydrogen phosphate aqueous solution to the zinc oxychloride aqueous solution to react to obtain a nano-scale zinc phosphate carrier, add a surfactant to control the particle size of the surfactant, and the added surfactant is CMC (hydroxymethyl cellulose ), the above-mentioned surfactants can also prevent the agglomeration between colloidal particles in the carrier precipitation process.
[0039] 2. Put the nano-zinc phosphate carrier into the ultrafiltration membrane system for filtration. The ultrafiltration membrane screening process is driven by the pressure difference on both sides of the membrane, and the ultrafiltration membrane is used as the filter medium. The micropores only allow water and small molecular substances to pass through to become the permeate, wh...
