A TEST CHAMBER FOR EMISSION OF NANOPARTICLES FROM NANOPRODUCTS

摘要

PURPOSE: A test chamber for testing an emission amount of a nano product is provided to evaluate possibilities of emitting a nano material being exposed to users in an actual usage environment and utilize a testing result as basic information for designing a safe nano product. CONSTITUTION: A test chamber for testing an emission amount of a nano product comprises a nano product mounting unit, a clean air feeding unit(60), an air discharge port(70), a sampling unit(80), an emitting unit(91). The clean air feeding unit comprises a purge air supplying unit minimizing pollution caused by indoor particles generated when mounting a specimen of a nano product. A speed of an air jet can be changed by changing the diameter of a nozzle in an emission mode by the air jet. A continuous jet or pulse jets of various periods can be utilized by controller a rotation speed of a rotating chopper or an opening/closing period of a solenoid valve in the emission mode by the air jet.
