Effect Of Bamboo Anti-mold And Analysis Of Its Surface Wetting After Ultrasonic Treatments

This paper explored the influence of ultrasonic dip treatment method on the effect of bamboofungi, wetting property on surface and the microstructure through comparing the differentresults among ultrasonic dip treatment, mold inhibitor dip treatment and ultrasonic and moldinhibitor dip combined treatment. A new environmental friendly method will be needed forbamboo anti-mold.The results showed as followings,There were differences on the appearance times of mold, molding rates and the mold masslosses among ultrasonic dip treatment, mold inhibitor dip treatment and ultrasonic and moldinhibitor dip combined treatment.The concentration of the mold inhibitor and the ultrasonic power were proportion to theappearing of mold fungi. The group treated by the ultrasonic and the mold inhibitor had nofungi on their surface in the experimental four weeks.The molding rates of the group treated by the ultrasonic were higher than those of the grouptreated by lower concentrations of mold inhibitor and those of lower concentrations than highergroups. The combined treatment got the best effect of anti-mold.The stronger the ultrasonic power was, the smaller the mass loss rate was. The moss loss of thtcombined group was zero.Starch grains in the bamboo parenchyma cells largely disappeared after ultrasonic treatment.There was no obvious breakdown phenomenon in neither parenchyma nor prothenchyma cells.The pits of bamboo also had no obvious changes.When the glycerol, UF (modified by MDI), PF were wetting the surfaces of bamboo, the valuesK were different due to the properties of liquids and different treatments.
