The Study Of Nanometer And Microencapsulate Phase Change Functional Air Filter Materials

The air pollution is strong harmful for the people's health .Improvingindoor air quality ,one effective way is filter air .Traditional air filtersonly capture dust ,but there are no effect on VOCs,smoke ,bacteria ,virus .Wepay attention to research the mutifountional air filters to eliminate the airpollution to improving indoor air quality.This research integrates photocatalysis technology and microencapsulatephase change materials technology into air filters.Nano-phase changefunctional air filters is developed by us.Finished process ,antibacterialeffect , regulating temperature , resistance and air filtration isresearched.The antibacterial of nano-phase change functional air filters isresearched under AATCC100 standard conducted .The result indicate thatnano-phase change functional air filters are most antibacterial effect amongof the mutifountional air filters .The regulating temperature of multi-functional air filters is tested by Intelligent Hand Tester.The structure of multifunctional air filters are observed by SEM. Thispaper discusses the feasibility of testing the pressure drop of air filtersusing air permeability tester.The resistance of air filter istested,analysising the reasons of increasing resistance of air filtersThe ANSI/AHAM AC-1-1988 standard is introduced. Testing the air efficiencyof multifunctional air filter conducted the standard . Compared withtraditional air filters, multifunctional air filets are higher efficiency .
