Test method for light stability of clear coatings 透明覆層光穩(wěn)定性試驗(yàn)方法
Application : lead stearate is the thermal stabilizer and lubricant for pvc with excellent thermal and light stability 用途:本品為聚氯乙稀熱穩(wěn)定劑,具有很好的潤滑性和較好的光、熱穩(wěn)定性。
This will avoid the trouble of hand operation and protect people ' s eyes by its special fuction of maintaining the light stability under fluctuate voltage 即可減少手動(dòng)調(diào)光的麻煩,又可以保護(hù)視力,同時(shí),它具有穩(wěn)光功能,當(dāng)電源電壓波動(dòng)時(shí),臺(tái)燈亮度保持不變。
Light stability of photo - ecology agricultural film was studied in this paper and has observed that the relation between yield of crops and luminescence intensity of photo - ecology agricultural film was positive correlation 研究了光生態(tài)膜的光穩(wěn)定性,觀察到作物的產(chǎn)量與光生態(tài)膜的發(fā)光強(qiáng)度呈正相關(guān)。
