DRK227 Synthetic blood penetration tester for surgical mask

Technical ntsuas:

1. Cov qauv tsim kho cov cuab yeej tuaj yeem simulate lub xeev siv tiag tiag ntawm lub npog ntsej muag, muab tso rau hauv qhov chaw kuaj lub hom phiaj yam tsis tau rhuav tshem cov qauv, thiab faib cov ntshav hluavtaws hauv thaj tsam ntawm cov qauv.

2. Cov cuab yeej tshwj xeeb ruaj khov-siab txhaj tshuaj tuaj yeem tshem tawm qee qhov ntim ntawm cov ntshav hluavtaws hauv lub sijhawm tswj.

3. Nws muaj peev xwm simulate qhov kev txhaj tshuaj ceev sib xws rau cov ntshav siab nruab nrab ntawm tib neeg lub cev ntawm 10.6kpa, 16kPa thiab 21.3kpa.

4. Lub hom phiaj ruaj khov yog tsim los thaiv qhov siab-siab ntug ib feem ntawm cov kua dej txhaj tshuaj thiab tsuas yog tso cai rau cov dej ntws tsis tu ncua yuav tsum tau txau rau ntawm tus qauv, uas ua rau kom qhov tseeb thiab rov ua dua ntawm cov kua tshaj tawm ntawm cov qauv.
