Shanghai Daoqin Plastics Co., Ltd.

 (1) lightfast (候) property and color agent use amount has lightfast (候) property color agent use amount increase has increase color agent use amount increase make surface 层 颜 material amount increase, in to 同样程 degree light lower, its lightfast property need color agent use amount small good. material concentrated degree increase to value 时, its lightfast property reinforcement to 极限.
  (2) lightfast (候) property and light time has lightfast (候) property for light time property strong/high. large more 数商 衰迟 is 直线, 一经暴晒. 就持续不断 改变. generally 面言: plastics color product weather resistant 澳2000h rear to 3缓 above, can outer use.
  (3) lightfast (候) property and add titanium powder has generally add titanium powder rear, material lightfast (候) property has degree decline, add more decline more.
  (4) lightfast (候) property and resin has in light lower has polymer color 泽变化 add 剧, from effect/influence products color 变化, add outer light stabilizer is can 行, decrease/reduce products color methods.
   polymer mono chemical property 质, polymerization methods and use antioxidant and light stabilizer same, material in product types plastics in lightfast (候) property can upper in 差异.
  (5) lightfast (候) property technology indicators and use full resistant (候) experiment/testing need very long however 客户不愿意 and other this long time, therefore research development in 实验室 in using/adopting light and accelerated parts lower lightfast (候) property methods. accelerated experiment/testing 基础都 is need use plant/unit separation different gas conditions, and also need to types experiment/testing principle between related property.
  一方面 is due to demand is can to full meet/satisfy; 另一方面 lightfast (候) property technology indicators in and between 会存偏差. however color and time non is 直线关系, has color is in 暴晒开 时候, 经 一段时候以 rear color 改变就停止. has 时候却恰恰 versus 反, 一开始暴晒不见何 改变, is 经 一 time rear color 改变才开始.
