实验结果:60支液晶屏完好,侧光观察比向光观察洁净度高。实验结论:清洗至8分钟(20℃)时效果较好,清洗实验结果与HEP-2相似但沸点低,挥发较严重。综述:对比CFC-113的清洗效果,HEP-2、HFC-245fa的清洗效果与之相近,但HFC-245fa明显挥发性严重,而Vertre SMT因挥发量太大,以至在室
Experimental results: 60 LCD screen intact, side light observation to the light observation of high cleanliness. Experimental conclusion: Cleaning to 8 minutes (20 ℃) when the effect is better, cleaning experiments and HEP-2 similar but with low boiling point, the more volatile. Summary: Compared with the cleaning effect of CFC-113, the cleaning effect of HEP-2 and HFC-245fa is similar to that of HFC-245fa, but the HFC-245fa is obviously volatile, whereas the Vertre SMT has too much volatile content,
