Mould and fire resistance of Phyllostachys edulis and Pinus massoniana treated with a nano antibiotic agent,TiO_2 doped-Ag

This study focused on mould and fire resistance of Phyllostachys edulis and Pinus massoniana treated with a nano antibiotic agent,TiO2 doped-Ag,at different concentrations(10,50,100,200 g·kg-1).Results showed that agent loading improved as the concentration of the nano antibiotic agent increased.Treatments were positive for mould resistance with initial mildew for treated bamboo appearing about 3 weeks later than the untreated and for treated Pinus massoniana about 4 weeks later than the untreated.In fire resistance,treated Phyllostachys edulis was about the same as untreated except for time to ignition(TTI) of treated Phyllostchys edulis which was 3-4 s longer.Also,treated Pinus massoniana was about the same as the untreated in effective heat of combustion(EHC),mass loss rate(MLR),and total smoke release(TSR),but heat release rate(HRR) and total heat release(THR) of the treated Pinus massoniana were lower than the untreated.
