During the second leak detection of a 600 MW unit project of a domestic power group, we found that the original customer was using a domestic brand of phosphor, which was packed in plastic bags with pigment written on it. We knew where the problem was. After confirmation, the brand of phosphor did not enter the dust collector, and there was a lot of loss. In addition, penetrating phosphor was found in each corner of the air purification chamber, so we need to check The leak failed.

Therefore, we suggest that customers must choose professional manufacturers to avoid causing more losses!

VKH®检漏荧光粉与市场上替代荧光粉的主要区别

                    VKH-11                            国产替代荧光粉                  危害

粒径 1—20um正态分布            平均粒径８um 0.2---60微米       大量粉未到达布袋即直接沉降灰斗。

                                                                                                   部份穿透，增加投粉量造成成本增加, 堵塞滤料

耐温 350℃分解后成粉末          110℃软化  110--190℃变为液态

                                               195℃化学分解出液体                    对清灰产生严重影响，造成滤料堵塞

主要成份为有机物Ｃaco3无毒               甲醛超标，重金属残留      对人体健康造成伤害，环境污染

发光机理  本身不发光，            原子衰变易衰竭自身发光来显色，有辐射        影响人体健康，检漏效果变差

通过光源激发，不衰竭
