fadeproof造句

• 90 % uv below 400nm could be shielded by the nano - sio2 sol . the time of the artificial aging of nano - sio2 - modified coatings prepared by the way of in - situ dispersion method was about twice as long as that of the nano - sio2 - modified coatings prepared by dispersing the nano - sio2 powder in the coating directly . on the other hand , the fadeproof time ( reaching the second level of color aberration ) of the nano - sio2 - modified coatings was 1 . 83 times as long as that of the national standard for the super coatings
  实验证明:纳米510 :溶胶具有很强的紫外散射屏蔽性能，对400nm以下的紫外光能屏蔽90 %以上;在位分散法纳米510 :改性涂料的耐人工老化粉化时间比直接分散法纳米510 :改性涂料提高了近1倍，耐变色时间(达到色差2级的时间)是国标优等品要求的1 . 83倍，较相应的未改性涂料提高了约25 % 。
• There was an increase in the fadeproof time of 25 percent over the common coatings . both the nano - tio2 - modified coatings prepared by the way of in - situ sythesising method and the nano - sio2 - modified coatings prepared by the way of in - situ dispersion were strong weatherability coatings , which could resist 18 years " weathering if we calculated the result with the standard which argued that 100h of the artificial aging process was equal
  通过原位生成法制备的纳米tio :改性涂料和在位分散法制备的纳米510 :改性涂料具有超强的耐候性能，以人工老化100h大约相当于室外曝晒一年计算，纳米改性的涂料在室外的使用寿命可超过18年。
