With the intensity of the electrostatic field changed, the freezing curve, the thawing curve and the number of the microbe are evaluated.

通过加电场以及改变电场强度大小，研究其冻结曲线和解冻曲线的变化；微生物指标的变化。

E. g. by ISO 834 curve thawing, fireproof performance reach 3h, general coating thickness need about 20 ~ 30 mm, Due to the coating thicker, requiring multiple coating, construction difficulties.

如按iso 834曲线升温，耐火性能达到3h，一般涂料涂层厚度约需20 ~ 30 mm；由于涂层较厚，需要多次喷涂，施工困难。
