The effect of the types,dispersion methods,amount on urea-formaldehyde(UF)resin is compared and the results show that nano-SiO2 has no effect on curing time of UF resin,but nano-SiO2 can greatly improve the wettability of veneer surfaces by UF resin,and that ultrasonic method has better dispersion effect than other dispersion methods and suitable addition amount of nanometer material is 1.
采用了四种纳米材料,比较其种类、分散方法及用量对UF胶主要性能的影响。
The unique structure of nanometer SiO_2,its property,dispersing method and the instruments employed were discussed.
分析了纳米SiO2的特殊结构和性能,介绍了纳米SiO2的分散方法与分散仪器。
